Significance of the Study

Definition:

Significance of the study in research refers to the potential importance, relevance, or impact of the research findings. It outlines how the research contributes to the existing body of knowledge, what gaps it fills, or what new understanding it brings to a particular field of study.

In general, the significance of a study can be assessed based on several factors, including:

• Originality : The extent to which the study advances existing knowledge or introduces new ideas and perspectives.
• Practical relevance: The potential implications of the study for real-world situations, such as improving policy or practice.
• Theoretical contribution: The extent to which the study provides new insights or perspectives on theoretical concepts or frameworks.
• Methodological rigor : The extent to which the study employs appropriate and robust methods and techniques to generate reliable and valid data.
• Social or cultural impact : The potential impact of the study on society, culture, or public perception of a particular issue.

Types of Significance of the Study

The significance of the Study can be divided into the following types:

Theoretical Significance

Theoretical significance refers to the contribution that a study makes to the existing body of theories in a specific field. This could be by confirming, refuting, or adding nuance to a currently accepted theory, or by proposing an entirely new theory.

Practical Significance

Practical significance refers to the direct applicability and usefulness of the research findings in real-world contexts. Studies with practical significance often address real-life problems and offer potential solutions or strategies. For example, a study in the field of public health might identify a new intervention that significantly reduces the spread of a certain disease.

Significance for Future Research

This pertains to the potential of a study to inspire further research. A study might open up new areas of investigation, provide new research methodologies, or propose new hypotheses that need to be tested.

How to Write Significance of the Study

Here’s a guide to writing an effective “Significance of the Study” section in research paper, thesis, or dissertation:

• Background : Begin by giving some context about your study. This could include a brief introduction to your subject area, the current state of research in the field, and the specific problem or question your study addresses.
• Identify the Gap : Demonstrate that there’s a gap in the existing literature or knowledge that needs to be filled, which is where your study comes in. The gap could be a lack of research on a particular topic, differing results in existing studies, or a new problem that has arisen and hasn’t yet been studied.
• State the Purpose of Your Study : Clearly state the main objective of your research. You may want to state the purpose as a solution to the problem or gap you’ve previously identified.
• Contributes to the existing body of knowledge.
• Addresses a significant research gap.
• Offers a new or better solution to a problem.
• Impacts policy or practice.
• Leads to improvements in a particular field or sector.
• Identify Beneficiaries : Identify who will benefit from your study. This could include other researchers, practitioners in your field, policy-makers, communities, businesses, or others. Explain how your findings could be used and by whom.
• Future Implications : Discuss the implications of your study for future research. This could involve questions that are left open, new questions that have been raised, or potential future methodologies suggested by your study.

Significance of the Study in Research Paper

The Significance of the Study in a research paper refers to the importance or relevance of the research topic being investigated. It answers the question “Why is this research important?” and highlights the potential contributions and impacts of the study.

The significance of the study can be presented in the introduction or background section of a research paper. It typically includes the following components:

• Importance of the research problem: This describes why the research problem is worth investigating and how it relates to existing knowledge and theories.
• Potential benefits and implications: This explains the potential contributions and impacts of the research on theory, practice, policy, or society.
• Originality and novelty: This highlights how the research adds new insights, approaches, or methods to the existing body of knowledge.
• Scope and limitations: This outlines the boundaries and constraints of the research and clarifies what the study will and will not address.

Suppose a researcher is conducting a study on the “Effects of social media use on the mental health of adolescents”.

The significance of the study may be:

“The present study is significant because it addresses a pressing public health issue of the negative impact of social media use on adolescent mental health. Given the widespread use of social media among this age group, understanding the effects of social media on mental health is critical for developing effective prevention and intervention strategies. This study will contribute to the existing literature by examining the moderating factors that may affect the relationship between social media use and mental health outcomes. It will also shed light on the potential benefits and risks of social media use for adolescents and inform the development of evidence-based guidelines for promoting healthy social media use among this population. The limitations of this study include the use of self-reported measures and the cross-sectional design, which precludes causal inference.”

Significance of the Study In Thesis

The significance of the study in a thesis refers to the importance or relevance of the research topic and the potential impact of the study on the field of study or society as a whole. It explains why the research is worth doing and what contribution it will make to existing knowledge.

For example, the significance of a thesis on “Artificial Intelligence in Healthcare” could be:

• With the increasing availability of healthcare data and the development of advanced machine learning algorithms, AI has the potential to revolutionize the healthcare industry by improving diagnosis, treatment, and patient outcomes. Therefore, this thesis can contribute to the understanding of how AI can be applied in healthcare and how it can benefit patients and healthcare providers.
• AI in healthcare also raises ethical and social issues, such as privacy concerns, bias in algorithms, and the impact on healthcare jobs. By exploring these issues in the thesis, it can provide insights into the potential risks and benefits of AI in healthcare and inform policy decisions.
• Finally, the thesis can also advance the field of computer science by developing new AI algorithms or techniques that can be applied to healthcare data, which can have broader applications in other industries or fields of research.

Significance of the Study in Research Proposal

The significance of a study in a research proposal refers to the importance or relevance of the research question, problem, or objective that the study aims to address. It explains why the research is valuable, relevant, and important to the academic or scientific community, policymakers, or society at large. A strong statement of significance can help to persuade the reviewers or funders of the research proposal that the study is worth funding and conducting.

Here is an example of a significance statement in a research proposal:

Title : The Effects of Gamification on Learning Programming: A Comparative Study

Significance Statement:

This proposed study aims to investigate the effects of gamification on learning programming. With the increasing demand for computer science professionals, programming has become a fundamental skill in the computer field. However, learning programming can be challenging, and students may struggle with motivation and engagement. Gamification has emerged as a promising approach to improve students’ engagement and motivation in learning, but its effects on programming education are not yet fully understood. This study is significant because it can provide valuable insights into the potential benefits of gamification in programming education and inform the development of effective teaching strategies to enhance students’ learning outcomes and interest in programming.

Examples of Significance of the Study

Here are some examples of the significance of a study that indicates how you can write this into your research paper according to your research topic:

Research on an Improved Water Filtration System : This study has the potential to impact millions of people living in water-scarce regions or those with limited access to clean water. A more efficient and affordable water filtration system can reduce water-borne diseases and improve the overall health of communities, enabling them to lead healthier, more productive lives.

Study on the Impact of Remote Work on Employee Productivity : Given the shift towards remote work due to recent events such as the COVID-19 pandemic, this study is of considerable significance. Findings could help organizations better structure their remote work policies and offer insights on how to maximize employee productivity, wellbeing, and job satisfaction.

Investigation into the Use of Solar Power in Developing Countries : With the world increasingly moving towards renewable energy, this study could provide important data on the feasibility and benefits of implementing solar power solutions in developing countries. This could potentially stimulate economic growth, reduce reliance on non-renewable resources, and contribute to global efforts to combat climate change.

Research on New Learning Strategies in Special Education : This study has the potential to greatly impact the field of special education. By understanding the effectiveness of new learning strategies, educators can improve their curriculum to provide better support for students with learning disabilities, fostering their academic growth and social development.

Examination of Mental Health Support in the Workplace : This study could highlight the impact of mental health initiatives on employee wellbeing and productivity. It could influence organizational policies across industries, promoting the implementation of mental health programs in the workplace, ultimately leading to healthier work environments.

Evaluation of a New Cancer Treatment Method : The significance of this study could be lifesaving. The research could lead to the development of more effective cancer treatments, increasing the survival rate and quality of life for patients worldwide.

When to Write Significance of the Study

The Significance of the Study section is an integral part of a research proposal or a thesis. This section is typically written after the introduction and the literature review. In the research process, the structure typically follows this order:

• Title – The name of your research.
• Abstract – A brief summary of the entire research.
• Introduction – A presentation of the problem your research aims to solve.
• Literature Review – A review of existing research on the topic to establish what is already known and where gaps exist.
• Significance of the Study – An explanation of why the research matters and its potential impact.

In the Significance of the Study section, you will discuss why your study is important, who it benefits, and how it adds to existing knowledge or practice in your field. This section is your opportunity to convince readers, and potentially funders or supervisors, that your research is valuable and worth undertaking.

Advantages of Significance of the Study

The Significance of the Study section in a research paper has multiple advantages:

• Establishes Relevance: This section helps to articulate the importance of your research to your field of study, as well as the wider society, by explicitly stating its relevance. This makes it easier for other researchers, funders, and policymakers to understand why your work is necessary and worth supporting.
• Guides the Research: Writing the significance can help you refine your research questions and objectives. This happens as you critically think about why your research is important and how it contributes to your field.
• Attracts Funding: If you are seeking funding or support for your research, having a well-written significance of the study section can be key. It helps to convince potential funders of the value of your work.
• Opens up Further Research: By stating the significance of the study, you’re also indicating what further research could be carried out in the future, based on your work. This helps to pave the way for future studies and demonstrates that your research is a valuable addition to the field.
• Provides Practical Applications: The significance of the study section often outlines how the research can be applied in real-world situations. This can be particularly important in applied sciences, where the practical implications of research are crucial.
• Enhances Understanding: This section can help readers understand how your study fits into the broader context of your field, adding value to the existing literature and contributing new knowledge or insights.

Limitations of Significance of the Study

The Significance of the Study section plays an essential role in any research. However, it is not without potential limitations. Here are some that you should be aware of:

• Subjectivity: The importance and implications of a study can be subjective and may vary from person to person. What one researcher considers significant might be seen as less critical by others. The assessment of significance often depends on personal judgement, biases, and perspectives.
• Predictability of Impact: While you can outline the potential implications of your research in the Significance of the Study section, the actual impact can be unpredictable. Research doesn’t always yield the expected results or have the predicted impact on the field or society.
• Difficulty in Measuring: The significance of a study is often qualitative and can be challenging to measure or quantify. You can explain how you think your research will contribute to your field or society, but measuring these outcomes can be complex.
• Possibility of Overstatement: Researchers may feel pressured to amplify the potential significance of their study to attract funding or interest. This can lead to overstating the potential benefits or implications, which can harm the credibility of the study if these results are not achieved.
• Overshadowing of Limitations: Sometimes, the significance of the study may overshadow the limitations of the research. It is important to balance the potential significance with a thorough discussion of the study’s limitations.
• Dependence on Successful Implementation: The significance of the study relies on the successful implementation of the research. If the research process has flaws or unexpected issues arise, the anticipated significance might not be realized.

What is the Significance of a Study? Examples and Guide

If you’re reading this post you’re probably wondering: what is the significance of a study?

No matter where you’re at with a piece of research, it is a good idea to think about the potential significance of your work. And sometimes you’ll have to explicitly write a statement of significance in your papers, it addition to it forming part of your thesis.

In this post I’ll cover what the significance of a study is, how to measure it, how to describe it with examples and add in some of my own experiences having now worked in research for over nine years.

If you’re reading this because you’re writing up your first paper, welcome! You may also like my how-to guide for all aspects of writing your first research paper .

Looking for guidance on writing the statement of significance for a paper or thesis? Click here to skip straight to that section.

What is the Significance of a Study?

For research papers, theses or dissertations it’s common to explicitly write a section describing the significance of the study. We’ll come onto what to include in that section in just a moment.

However the significance of a study can actually refer to several different things.

Working our way from the most technical to the broadest, depending on the context, the significance of a study may refer to:

• Within your study: Statistical significance. Can we trust the findings?
• Wider research field: Research significance. How does your study progress the field?
• Commercial / economic significance: Could there be business opportunities for your findings?
• Societal significance: What impact could your study have on the wider society.
• And probably other domain-specific significance!

We’ll shortly cover each of them in turn, including how they’re measured and some examples for each type of study significance.

But first, let’s touch on why you should consider the significance of your research at an early stage.

Why Care About the Significance of a Study?

No matter what is motivating you to carry out your research, it is sensible to think about the potential significance of your work. In the broadest sense this asks, how does the study contribute to the world?

After all, for many people research is only worth doing if it will result in some expected significance. For the vast majority of us our studies won’t be significant enough to reach the evening news, but most studies will help to enhance knowledge in a particular field and when research has at least some significance it makes for a far more fulfilling longterm pursuit.

Furthermore, a lot of us are carrying out research funded by the public. It therefore makes sense to keep an eye on what benefits the work could bring to the wider community.

Often in research you’ll come to a crossroads where you must decide which path of research to pursue. Thinking about the potential benefits of a strand of research can be useful for deciding how to spend your time, money and resources.

It’s worth noting though, that not all research activities have to work towards obvious significance. This is especially true while you’re a PhD student, where you’re figuring out what you enjoy and may simply be looking for an opportunity to learn a new skill.

However, if you’re trying to decide between two potential projects, it can be useful to weigh up the potential significance of each.

Let’s now dive into the different types of significance, starting with research significance.

Research Significance

What is the research significance of a study.

Unless someone specifies which type of significance they’re referring to, it is fair to assume that they want to know about the research significance of your study.

Research significance describes how your work has contributed to the field, how it could inform future studies and progress research.

Where should I write about my study’s significance in my thesis?

Typically you should write about your study’s significance in the Introduction and Conclusions sections of your thesis.

It’s important to mention it in the Introduction so that the relevance of your work and the potential impact and benefits it could have on the field are immediately apparent. Explaining why your work matters will help to engage readers (and examiners!) early on.

It’s also a good idea to detail the study’s significance in your Conclusions section. This adds weight to your findings and helps explain what your study contributes to the field.

On occasion you may also choose to include a brief description in your Abstract.

What is expected when submitting an article to a journal

It is common for journals to request a statement of significance, although this can sometimes be called other things such as:

• Impact statement
• Significance statement
• Advances in knowledge section

Here is one such example of what is expected:

Impact Statement:  An Impact Statement is required for all submissions.  Your impact statement will be evaluated by the Editor-in-Chief, Global Editors, and appropriate Associate Editor. For your manuscript to receive full review, the editors must be convinced that it is an important advance in for the field. The Impact Statement is not a restating of the abstract. It should address the following: Why is the work submitted important to the field? How does the work submitted advance the field? What new information does this work impart to the field? How does this new information impact the field? Experimental Biology and Medicine journal, author guidelines

Typically the impact statement will be shorter than the Abstract, around 150 words.

Defining the study’s significance is helpful not just for the impact statement (if the journal asks for one) but also for building a more compelling argument throughout your submission. For instance, usually you’ll start the Discussion section of a paper by highlighting the research significance of your work. You’ll also include a short description in your Abstract too.

How to describe the research significance of a study, with examples

Whether you’re writing a thesis or a journal article, the approach to writing about the significance of a study are broadly the same.

I’d therefore suggest using the questions above as a starting point to base your statements on.

• Why is the work submitted important to the field?
• How does the work submitted advance the field?
• What new information does this work impart to the field?
• How does this new information impact the field?

Answer those questions and you’ll have a much clearer idea of the research significance of your work.

When describing it, try to clearly state what is novel about your study’s contribution to the literature. Then go on to discuss what impact it could have on progressing the field along with recommendations for future work.

Potential sentence starters

If you’re not sure where to start, why not set a 10 minute timer and have a go at trying to finish a few of the following sentences. Not sure on what to put? Have a chat to your supervisor or lab mates and they may be able to suggest some ideas.

• This study is important to the field because…
• These findings advance the field by…
• Our results highlight the importance of…
• Our discoveries impact the field by…

Now you’ve had a go let’s have a look at some real life examples.

Statement of significance examples

A statement of significance / impact:

Impact Statement This review highlights the historical development of the concept of “ideal protein” that began in the 1950s and 1980s for poultry and swine diets, respectively, and the major conceptual deficiencies of the long-standing concept of “ideal protein” in animal nutrition based on recent advances in amino acid (AA) metabolism and functions. Nutritionists should move beyond the “ideal protein” concept to consider optimum ratios and amounts of all proteinogenic AAs in animal foods and, in the case of carnivores, also taurine. This will help formulate effective low-protein diets for livestock, poultry, and fish, while sustaining global animal production. Because they are not only species of agricultural importance, but also useful models to study the biology and diseases of humans as well as companion (e.g. dogs and cats), zoo, and extinct animals in the world, our work applies to a more general readership than the nutritionists and producers of farm animals. Wu G, Li P. The “ideal protein” concept is not ideal in animal nutrition.  Experimental Biology and Medicine . 2022;247(13):1191-1201. doi: 10.1177/15353702221082658

And the same type of section but this time called “Advances in knowledge”:

Advances in knowledge: According to the MY-RADs criteria, size measurements of focal lesions in MRI are now of relevance for response assessment in patients with monoclonal plasma cell disorders. Size changes of 1 or 2 mm are frequently observed due to uncertainty of the measurement only, while the actual focal lesion has not undergone any biological change. Size changes of at least 6 mm or more in  T 1  weighted or  T 2  weighted short tau inversion recovery sequences occur in only 5% or less of cases when the focal lesion has not undergone any biological change. Wennmann M, Grözinger M, Weru V, et al. Test-retest, inter- and intra-rater reproducibility of size measurements of focal bone marrow lesions in MRI in patients with multiple myeloma [published online ahead of print, 2023 Apr 12].  Br J Radiol . 2023;20220745. doi: 10.1259/bjr.20220745

Other examples of research significance

Moving beyond the formal statement of significance, here is how you can describe research significance more broadly within your paper.

Describing research impact in an Abstract of a paper:

Three-dimensional visualisation and quantification of the chondrocyte population within articular cartilage can be achieved across a field of view of several millimetres using laboratory-based micro-CT. The ability to map chondrocytes in 3D opens possibilities for research in fields from skeletal development through to medical device design and treatment of cartilage degeneration. Conclusions section of the abstract in my first paper .

In the Discussion section of a paper:

We report for the utility of a standard laboratory micro-CT scanner to visualise and quantify features of the chondrocyte population within intact articular cartilage in 3D. This study represents a complimentary addition to the growing body of evidence supporting the non-destructive imaging of the constituents of articular cartilage. This offers researchers the opportunity to image chondrocyte distributions in 3D without specialised synchrotron equipment, enabling investigations such as chondrocyte morphology across grades of cartilage damage, 3D strain mapping techniques such as digital volume correlation to evaluate mechanical properties  in situ , and models for 3D finite element analysis  in silico  simulations. This enables an objective quantification of chondrocyte distribution and morphology in three dimensions allowing greater insight for investigations into studies of cartilage development, degeneration and repair. One such application of our method, is as a means to provide a 3D pattern in the cartilage which, when combined with digital volume correlation, could determine 3D strain gradient measurements enabling potential treatment and repair of cartilage degeneration. Moreover, the method proposed here will allow evaluation of cartilage implanted with tissue engineered scaffolds designed to promote chondral repair, providing valuable insight into the induced regenerative process. The Discussion section of the paper is laced with references to research significance.

How is longer term research significance measured?

Looking beyond writing impact statements within papers, sometimes you’ll want to quantify the long term research significance of your work. For instance when applying for jobs.

The most obvious measure of a study’s long term research significance is the number of citations it receives from future publications. The thinking is that a study which receives more citations will have had more research impact, and therefore significance , than a study which received less citations. Citations can give a broad indication of how useful the work is to other researchers but citations aren’t really a good measure of significance.

Bear in mind that us researchers can be lazy folks and sometimes are simply looking to cite the first paper which backs up one of our claims. You can find studies which receive a lot of citations simply for packaging up the obvious in a form which can be easily found and referenced, for instance by having a catchy or optimised title.

Likewise, research activity varies wildly between fields. Therefore a certain study may have had a big impact on a particular field but receive a modest number of citations, simply because not many other researchers are working in the field.

Nevertheless, citations are a standard measure of significance and for better or worse it remains impressive for someone to be the first author of a publication receiving lots of citations.

Other measures for the research significance of a study include:

• Accolades: best paper awards at conferences, thesis awards, “most downloaded” titles for articles, press coverage.
• How much follow-on research the study creates. For instance, part of my PhD involved a novel material initially developed by another PhD student in the lab. That PhD student’s research had unlocked lots of potential new studies and now lots of people in the group were using the same material and developing it for different applications. The initial study may not receive a high number of citations yet long term it generated a lot of research activity.

That covers research significance, but you’ll often want to consider other types of significance for your study and we’ll cover those next.

Statistical Significance

What is the statistical significance of a study.

Often as part of a study you’ll carry out statistical tests and then state the statistical significance of your findings: think p-values eg <0.05. It is useful to describe the outcome of these tests within your report or paper, to give a measure of statistical significance.

Effectively you are trying to show whether the performance of your innovation is actually better than a control or baseline and not just chance. Statistical significance deserves a whole other post so I won’t go into a huge amount of depth here.

Things that make publication in  The BMJ  impossible or unlikely Internal validity/robustness of the study • It had insufficient statistical power, making interpretation difficult; • Lack of statistical power; The British Medical Journal’s guide for authors

Calculating statistical significance isn’t always necessary (or valid) for a study, such as if you have a very small number of samples, but it is a very common requirement for scientific articles.

Writing a journal article? Check the journal’s guide for authors to see what they expect. Generally if you have approximately five or more samples or replicates it makes sense to start thinking about statistical tests. Speak to your supervisor and lab mates for advice, and look at other published articles in your field.

How is statistical significance measured?

Statistical significance is quantified using p-values . Depending on your study design you’ll choose different statistical tests to compute the p-value.

A p-value of 0.05 is a common threshold value. The 0.05 means that there is a 1/20 chance that the difference in performance you’re reporting is just down to random chance.

• p-values above 0.05 mean that the result isn’t statistically significant enough to be trusted: it is too likely that the effect you’re showing is just luck.
• p-values less than or equal to 0.05 mean that the result is statistically significant. In other words: unlikely to just be chance, which is usually considered a good outcome.

Low p-values (eg p = 0.001) mean that it is highly unlikely to be random chance (1/1000 in the case of p = 0.001), therefore more statistically significant.

It is important to clarify that, although low p-values mean that your findings are statistically significant, it doesn’t automatically mean that the result is scientifically important. More on that in the next section on research significance.

How to describe the statistical significance of your study, with examples

In the first paper from my PhD I ran some statistical tests to see if different staining techniques (basically dyes) increased how well you could see cells in cow tissue using micro-CT scanning (a 3D imaging technique).

In your methods section you should mention the statistical tests you conducted and then in the results you will have statements such as:

Between mediums for the two scan protocols C/N [contrast to noise ratio] was greater for EtOH than the PBS in both scanning methods (both  p  < 0.0001) with mean differences of 1.243 (95% CI [confidence interval] 0.709 to 1.778) for absorption contrast and 6.231 (95% CI 5.772 to 6.690) for propagation contrast. … Two repeat propagation scans were taken of samples from the PTA-stained groups. No difference in mean C/N was found with either medium: PBS had a mean difference of 0.058 ( p  = 0.852, 95% CI -0.560 to 0.676), EtOH had a mean difference of 1.183 ( p  = 0.112, 95% CI 0.281 to 2.648). From the Results section of my first paper, available here . Square brackets added for this post to aid clarity.

From this text the reader can infer from the first paragraph that there was a statistically significant difference in using EtOH compared to PBS (really small p-value of <0.0001). However, from the second paragraph, the difference between two repeat scans was statistically insignificant for both PBS (p = 0.852) and EtOH (p = 0.112).

By conducting these statistical tests you have then earned your right to make bold statements, such as these from the discussion section:

Propagation phase-contrast increases the contrast of individual chondrocytes [cartilage cells] compared to using absorption contrast. From the Discussion section from the same paper.

Without statistical tests you have no evidence that your results are not just down to random chance.

Beyond describing the statistical significance of a study in the main body text of your work, you can also show it in your figures.

In figures such as bar charts you’ll often see asterisks to represent statistical significance, and “n.s.” to show differences between groups which are not statistically significant. Here is one such figure, with some subplots, from the same paper:

In this example an asterisk (*) between two bars represents p < 0.05. Two asterisks (**) represents p < 0.001 and three asterisks (***) represents p < 0.0001. This should always be stated in the caption of your figure since the values that each asterisk refers to can vary.

Now that we know if a study is showing statistically and research significance, let’s zoom out a little and consider the potential for commercial significance.

Commercial and Industrial Significance

What are commercial and industrial significance.

Moving beyond significance in relation to academia, your research may also have commercial or economic significance.

Simply put:

• Commercial significance: could the research be commercialised as a product or service? Perhaps the underlying technology described in your study could be licensed to a company or you could even start your own business using it.
• Industrial significance: more widely than just providing a product which could be sold, does your research provide insights which may affect a whole industry? Such as: revealing insights or issues with current practices, performance gains you don’t want to commercialise (e.g. solar power efficiency), providing suggested frameworks or improvements which could be employed industry-wide.

I’ve grouped these two together because there can certainly be overlap. For instance, perhaps your new technology could be commercialised whilst providing wider improvements for the whole industry.

Commercial and industrial significance are not relevant to most studies, so only write about it if you and your supervisor can think of reasonable routes to your work having an impact in these ways.

How are commercial and industrial significance measured?

Unlike statistical and research significances, the measures of commercial and industrial significance can be much more broad.

Here are some potential measures of significance:

Commercial significance:

• How much value does your technology bring to potential customers or users?
• How big is the potential market and how much revenue could the product potentially generate?
• Is the intellectual property protectable? i.e. patentable, or if not could the novelty be protected with trade secrets: if so publish your method with caution!
• If commercialised, could the product bring employment to a geographical area?

Industrial significance:

What impact could it have on the industry? For instance if you’re revealing an issue with something, such as unintended negative consequences of a drug , what does that mean for the industry and the public? This could be:

• Reduced overhead costs
• Better safety
• Faster production methods
• Improved scaleability

How to describe the commercial and industrial significance of a study, with examples

Commercial significance.

If your technology could be commercially viable, and you’ve got an interest in commercialising it yourself, it is likely that you and your university may not want to immediately publish the study in a journal.

You’ll probably want to consider routes to exploiting the technology and your university may have a “technology transfer” team to help researchers navigate the various options.

However, if instead of publishing a paper you’re submitting a thesis or dissertation then it can be useful to highlight the commercial significance of your work. In this instance you could include statements of commercial significance such as:

The measurement technology described in this study provides state of the art performance and could enable the development of low cost devices for aerospace applications. An example of commercial significance I invented for this post

Industrial significance

First, think about the industrial sectors who could benefit from the developments described in your study.

For example if you’re working to improve battery efficiency it is easy to think of how it could lead to performance gains for certain industries, like personal electronics or electric vehicles. In these instances you can describe the industrial significance relatively easily, based off your findings.

For example:

By utilising abundant materials in the described battery fabrication process we provide a framework for battery manufacturers to reduce dependence on rare earth components. Again, an invented example

For other technologies there may well be industrial applications but they are less immediately obvious and applicable. In these scenarios the best you can do is to simply reframe your research significance statement in terms of potential commercial applications in a broad way.

As a reminder: not all studies should address industrial significance, so don’t try to invent applications just for the sake of it!

Societal Significance

What is the societal significance of a study.

The most broad category of significance is the societal impact which could stem from it.

If you’re working in an applied field it may be quite easy to see a route for your research to impact society. For others, the route to societal significance may be less immediate or clear.

Studies can help with big issues facing society such as:

• Medical applications : vaccines, surgical implants, drugs, improving patient safety. For instance this medical device and drug combination I worked on which has a very direct route to societal significance.
• Political significance : Your research may provide insights which could contribute towards potential changes in policy or better understanding of issues facing society.
• Public health : for instance COVID-19 transmission and related decisions.
• Climate change : mitigation such as more efficient solar panels and lower cost battery solutions, and studying required adaptation efforts and technologies. Also, better understanding around related societal issues, for instance this study on the effects of temperature on hate speech.

How is societal significance measured?

Societal significance at a high level can be quantified by the size of its potential societal effect. Just like a lab risk assessment, you can think of it in terms of probability (or how many people it could help) and impact magnitude.

Societal impact = How many people it could help x the magnitude of the impact

Think about how widely applicable the findings are: for instance does it affect only certain people? Then think about the potential size of the impact: what kind of difference could it make to those people?

Between these two metrics you can get a pretty good overview of the potential societal significance of your research study.

How to describe the societal significance of a study, with examples

Quite often the broad societal significance of your study is what you’re setting the scene for in your Introduction. In addition to describing the existing literature, it is common to for the study’s motivation to touch on its wider impact for society.

For those of us working in healthcare research it is usually pretty easy to see a path towards societal significance.

Our CLOUT model has state-of-the-art performance in mortality prediction, surpassing other competitive NN models and a logistic regression model … Our results show that the risk factors identified by the CLOUT model agree with physicians’ assessment, suggesting that CLOUT could be used in real-world clinicalsettings. Our results strongly support that CLOUT may be a useful tool to generate clinical prediction models, especially among hospitalized and critically ill patient populations.

In other domains the societal significance may either take longer or be more indirect, meaning that it can be more difficult to describe the societal impact.

Even so, here are some examples I’ve found from studies in non-healthcare domains:

We examined food waste as an initial investigation and test of this methodology, and there is clear potential for the examination of not only other policy texts related to food waste (e.g., liability protection, tax incentives, etc.; Broad Leib et al., 2020) but related to sustainable fishing (Worm et al., 2006) and energy use (Hawken, 2017). These other areas are of obvious relevance to climate change… AI-Based Text Analysis for Evaluating Food Waste Policies

What is the Significance of the Study?

• By DiscoverPhDs
• August 25, 2020

• what the significance of the study means,
• why it’s important to include in your research work,
• where you would include it in your paper, thesis or dissertation,
• how you write one
• and finally an example of a well written section about the significance of the study.

What does Significance of the Study mean?

The significance of the study is a written statement that explains why your research was needed. It’s a justification of the importance of your work and impact it has on your research field, it’s contribution to new knowledge and how others will benefit from it.

Why is the Significance of the Study important?

The significance of the study, also known as the rationale of the study, is important to convey to the reader why the research work was important. This may be an academic reviewer assessing your manuscript under peer-review, an examiner reading your PhD thesis, a funder reading your grant application or another research group reading your published journal paper. Your academic writing should make clear to the reader what the significance of the research that you performed was, the contribution you made and the benefits of it.

How do you write the Significance of the Study?

When writing this section, first think about where the gaps in knowledge are in your research field. What are the areas that are poorly understood with little or no previously published literature? Or what topics have others previously published on that still require further work. This is often referred to as the problem statement.

The introduction section within the significance of the study should include you writing the problem statement and explaining to the reader where the gap in literature is.

Then think about the significance of your research and thesis study from two perspectives: (1) what is the general contribution of your research on your field and (2) what specific contribution have you made to the knowledge and who does this benefit the most.

For example, the gap in knowledge may be that the benefits of dumbbell exercises for patients recovering from a broken arm are not fully understood. You may have performed a study investigating the impact of dumbbell training in patients with fractures versus those that did not perform dumbbell exercises and shown there to be a benefit in their use. The broad significance of the study would be the improvement in the understanding of effective physiotherapy methods. Your specific contribution has been to show a significant improvement in the rate of recovery in patients with broken arms when performing certain dumbbell exercise routines.

This statement should be no more than 500 words in length when written for a thesis. Within a research paper, the statement should be shorter and around 200 words at most.

Significance of the Study: An example

Building on the above hypothetical academic study, the following is an example of a full statement of the significance of the study for you to consider when writing your own. Keep in mind though that there’s no single way of writing the perfect significance statement and it may well depend on the subject area and the study content.

Here’s another example to help demonstrate how a significance of the study can also be applied to non-technical fields:

The significance of this research lies in its potential to inform clinical practices and patient counseling. By understanding the psychological outcomes associated with non-surgical facial aesthetics, practitioners can better guide their patients in making informed decisions about their treatment plans. Additionally, this study contributes to the body of academic knowledge by providing empirical evidence on the effects of these cosmetic procedures, which have been largely anecdotal up to this point.

The statement of the significance of the study is used by students and researchers in academic writing to convey the importance of the research performed; this section is written at the end of the introduction and should describe the specific contribution made and who it benefits.

Related: How to Make Conceptual Framework (with Examples and Templates)

Why Should I Include the Significance of the Study?

The purpose of the Significance of the Study is to give you space to explain to your readers how exactly your research will be contributing to the literature of the field you are studying 1 . It’s where you explain why your research is worth conducting and its significance to the community, the people, and various institutions.

How To Write Significance of the Study: 5 Steps

Below are the steps and guidelines for writing your research’s Significance of the Study.

1. Use Your Research Problem as a Starting Point

Your problem statement can provide clues to your research study’s outcome and who will benefit from it 2 .

Ask yourself, “How will the answers to my research problem be beneficial?”. In this manner, you will know how valuable it is to conduct your study. 

Let’s say your research problem is “What is the level of effectiveness of the lemongrass (Cymbopogon citratus) in lowering the blood glucose level of Swiss mice (Mus musculus)?”

Discovering a positive correlation between the use of lemongrass and lower blood glucose level may lead to the following results:

• Increased public understanding of the plant’s medical properties;
• Higher appreciation of the importance of lemongrass  by the community;
• Adoption of lemongrass tea as a cheap, readily available, and natural remedy to lower their blood glucose level.

Once you’ve zeroed in on the general benefits of your study, it’s time to break it down into specific beneficiaries.

2. State How Your Research Will Contribute to the Existing Literature in the Field

Think of the things that were not explored by previous studies. Then, write how your research tackles those unexplored areas. Through this, you can convince your readers that you are studying something new and adding value to the field.

3. Explain How Your Research Will Benefit Society

In this part, tell how your research will impact society. Think of how the results of your study will change something in your community. 

For example, in the study about using lemongrass tea to lower blood glucose levels, you may indicate that through your research, the community will realize the significance of lemongrass and other herbal plants. As a result, the community will be encouraged to promote the cultivation and use of medicinal plants.

4. Mention the Specific Persons or Institutions Who Will Benefit From Your Study

Using the same example above, you may indicate that this research’s results will benefit those seeking an alternative supplement to prevent high blood glucose levels.

5. Indicate How Your Study May Help Future Studies in the Field

You must also specifically indicate how your research will be part of the literature of your field and how it will benefit future researchers. In our example above, you may indicate that through the data and analysis your research will provide, future researchers may explore other capabilities of herbal plants in preventing different diseases.

Tips and Warnings

• Think ahead . By visualizing your study in its complete form, it will be easier for you to connect the dots and identify the beneficiaries of your research.
• Write concisely. Make it straightforward, clear, and easy to understand so that the readers will appreciate the benefits of your research. Avoid making it too long and wordy.
• Go from general to specific . Like an inverted pyramid, you start from above by discussing the general contribution of your study and become more specific as you go along. For instance, if your research is about the effect of remote learning setup on the mental health of college students of a specific university , you may start by discussing the benefits of the research to society, to the educational institution, to the learning facilitators, and finally, to the students.
• Seek help . For example, you may ask your research adviser for insights on how your research may contribute to the existing literature. If you ask the right questions, your research adviser can point you in the right direction.
• Revise, revise, revise. Be ready to apply necessary changes to your research on the fly. Unexpected things require adaptability, whether it’s the respondents or variables involved in your study. There’s always room for improvement, so never assume your work is done until you have reached the finish line.

How To Write a Significance Statement for Your Research

A significance statement is an essential part of a research paper. It explains the importance and relevance of the study to the academic community and the world at large. To write a compelling significance statement, identify the research problem, explain why it is significant, provide evidence of its importance, and highlight its potential impact on future research, policy, or practice. A well-crafted significance statement should effectively communicate the value of the research to readers and help them understand why it matters.

Updated on May 4, 2023

A significance statement is a clearly stated, non-technical paragraph that explains why your research matters. It’s central in making the public aware of and gaining support for your research.

Write it in jargon-free language that a reader from any field can understand. Well-crafted, easily readable significance statements can improve your chances for citation and impact and make it easier for readers outside your field to find and understand your work.

Read on for more details on what a significance statement is, how it can enhance the impact of your research, and, of course, how to write one.

What is a significance statement in research?

A significance statement answers the question: How will your research advance scientific knowledge and impact society at large (as well as specific populations)? 

You might also see it called a “Significance of the study” statement. Some professional organizations in the STEM sciences and social sciences now recommended that journals in their disciplines make such statements a standard feature of each published article. Funding agencies also consider “significance” a key criterion for their awards.

Read some examples of significance statements from the Proceedings of the National Academy of Sciences (PNAS) here .

Depending upon the specific journal or funding agency’s requirements, your statement may be around 100 words and answer these questions:

1. What’s the purpose of this research?

2. What are its key findings?

3. Why do they matter?

4. Who benefits from the research results?

Readers will want to know: “What is interesting or important about this research?” Keep asking yourself that question.

Where to place the significance statement in your manuscript

Most journals ask you to place the significance statement before or after the abstract, so check with each journal’s guide. 

This article is focused on the formal significance statement, even though you’ll naturally highlight your project’s significance elsewhere in your manuscript. (In the introduction, you’ll set out your research aims, and in the conclusion, you’ll explain the potential applications of your research and recommend areas for future research. You’re building an overall case for the value of your work.)

Developing the significance statement

The main steps in planning and developing your statement are to assess the gaps to which your study contributes, and then define your work’s implications and impact.

Identify what gaps your study fills and what it contributes

Your literature review was a big part of how you planned your study. To develop your research aims and objectives, you identified gaps or unanswered questions in the preceding research and designed your study to address them.

Go back to that lit review and look at those gaps again. Review your research proposal to refresh your memory. Ask:

• How have my research findings advanced knowledge or provided notable new insights?
• How has my research helped to prove (or disprove) a hypothesis or answer a research question?
• Why are those results important?

Consider your study’s potential impact at two levels: 

• What contribution does my research make to my field?
• How does it specifically contribute to knowledge; that is, who will benefit the most from it?

Define the implications and potential impact

As you make notes, keep the reasons in mind for why you are writing this statement. Whom will it impact, and why?

The first audience for your significance statement will be journal reviewers when you submit your article for publishing. Many journals require one for manuscript submissions. Study the author’s guide of your desired journal to see its criteria ( here’s an example ). Peer reviewers who can clearly understand the value of your research will be more likely to recommend publication. 

Second, when you apply for funding, your significance statement will help justify why your research deserves a grant from a funding agency . The U.S. National Institutes of Health (NIH), for example, wants to see that a project will “exert a sustained, powerful influence on the research field(s) involved.” Clear, simple language is always valuable because not all reviewers will be specialists in your field.

Third, this concise statement about your study’s importance can affect how potential readers engage with your work. Science journalists and interested readers can promote and spread your work, enhancing your reputation and influence. Help them understand your work.

You’re now ready to express the importance of your research clearly and concisely. Time to start writing.

How to write a significance statement: Key elements 

When drafting your statement, focus on both the content and writing style.

• In terms of content, emphasize the importance, timeliness, and relevance of your research results. 
• Write the statement in plain, clear language rather than scientific or technical jargon. Your audience will include not just your fellow scientists but also non-specialists like journalists, funding reviewers, and members of the public. 

Follow the process we outline below to build a solid, well-crafted, and informative statement. 

Get started

Some suggested opening lines to help you get started might be:

• The implications of this study are… 
• Building upon previous contributions, our study moves the field forward because…
• Our study furthers previous understanding about…

Alternatively, you may start with a statement about the phenomenon you’re studying, leading to the problem statement.

Include these components

Next, draft some sentences that include the following elements. A good example, which we’ll use here, is a significance statement by Rogers et al. (2022) published in the Journal of Climate .

1. Briefly situate your research study in its larger context . Start by introducing the topic, leading to a problem statement. Here’s an example:

‘Heatwaves pose a major threat to human health, ecosystems, and human systems.”

2. State the research problem.

“Simultaneous heatwaves affecting multiple regions can exacerbate such threats. For example, multiple food-producing regions simultaneously undergoing heat-related crop damage could drive global food shortages.”

3. Tell what your study does to address it.

“We assess recent changes in the occurrence of simultaneous large heatwaves.”

4. Provide brief but powerful evidence to support the claims your statement is making , Use quantifiable terms rather than vague ones (e.g., instead of “This phenomenon is happening now more than ever,” see below how Rogers et al. (2022) explained it). This evidence intensifies and illustrates the problem more vividly:

“Such simultaneous heatwaves are 7 times more likely now than 40 years ago. They are also hotter and affect a larger area. Their increasing occurrence is mainly driven by warming baseline temperatures due to global heating, but changes in weather patterns contribute to disproportionate increases over parts of Europe, the eastern United States, and Asia.

5. Relate your study’s impact to the broader context , starting with its general significance to society—then, when possible, move to the particular as you name specific applications of your research findings. (Our example lacks this second level of application.) 

“Better understanding the drivers of weather pattern changes is therefore important for understanding future concurrent heatwave characteristics and their impacts.”

Refine your English

Don’t understate or overstate your findings – just make clear what your study contributes. When you have all the elements in place, review your draft to simplify and polish your language. Even better, get an expert AJE edit . Be sure to use “plain” language rather than academic jargon.

• Avoid acronyms, scientific jargon, and technical terms 
• Use active verbs in your sentence structure rather than passive voice (e.g., instead of “It was found that...”, use “We found...”)
• Make sentence structures short, easy to understand – readable
• Try to address only one idea in each sentence and keep sentences within 25 words (15 words is even better)
• Eliminate nonessential words and phrases (“fluff” and wordiness)

Enhance your significance statement’s impact

Always take time to review your draft multiple times. Make sure that you:

• Keep your language focused
• Provide evidence to support your claims
• Relate the significance to the broader research context in your field

After revising your significance statement, request feedback from a reading mentor about how to make it even clearer. If you’re not a native English speaker, seek help from a native-English-speaking colleague or use an editing service like AJE to make sure your work is at a native level.

Understanding the significance of your study

Your readers may have much less interest than you do in the specific details of your research methods and measures. Many readers will scan your article to learn how your findings might apply to them and their own research. 

Different types of significance

Your findings may have different types of significance, relevant to different populations or fields of study for different reasons. You can emphasize your work’s statistical, clinical, or practical significance. Editors or reviewers in the social sciences might also evaluate your work’s social or political significance.

Statistical significance means that the results are unlikely to have occurred randomly. Instead, it implies a true cause-and-effect relationship.

Clinical significance means that your findings are applicable for treating patients and improving quality of life.

Practical significance is when your research outcomes are meaningful to society at large, in the “real world.” Practical significance is usually measured by the study’s  effect size . Similarly, evaluators may attribute social or political significance to research that addresses “real and immediate” social problems.

How to Discuss the Significance of Your Research

• 6-minute read
• 10th April 2023

Introduction

Research papers can be a real headache for college students . As a student, your research needs to be credible enough to support your thesis statement. You must also ensure you’ve discussed the literature review, findings, and results.

However, it’s also important to discuss the significance of your research . Your potential audience will care deeply about this. It will also help you conduct your research. By knowing the impact of your research, you’ll understand what important questions to answer.

If you’d like to know more about the impact of your research, read on! We’ll talk about why it’s important and how to discuss it in your paper.

What Is the Significance of Research?

This is the potential impact of your research on the field of study. It includes contributions from new knowledge from the research and those who would benefit from it. You should present this before conducting research, so you need to be aware of current issues associated with the thesis before discussing the significance of the research.

Why Does the Significance of Research Matter?

Potential readers need to know why your research is worth pursuing. Discussing the significance of research answers the following questions:

●  Why should people read your research paper ?

●  How will your research contribute to the current knowledge related to your topic?

●  What potential impact will it have on the community and professionals in the field?

Not including the significance of research in your paper would be like a knight trying to fight a dragon without weapons.

Where Do I Discuss the Significance of Research in My Paper?

As previously mentioned, the significance of research comes before you conduct it. Therefore, you should discuss the significance of your research in the Introduction section. Your reader should know the problem statement and hypothesis beforehand.

Steps to Discussing the Significance of Your Research

Discussing the significance of research might seem like a loaded question, so we’ve outlined some steps to help you tackle it.

Step 1: The Research Problem

The problem statement can reveal clues about the outcome of your research. Your research should provide answers to the problem, which is beneficial to all those concerned. For example, imagine the problem statement is, “To what extent do elementary and high school teachers believe cyberbullying affects student performance?”

Learning teachers’ opinions on the effects of cyberbullying on student performance could result in the following:

●  Increased public awareness of cyberbullying in elementary and high schools

●  Teachers’ perceptions of cyberbullying negatively affecting student performance

●  Whether cyberbullying is more prevalent in elementary or high schools

The research problem will steer your research in the right direction, so it’s best to start with the problem statement.

Step 2: Existing Literature in the Field

Think about current information on your topic, and then find out what information is missing. Are there any areas that haven’t been explored? Your research should add new information to the literature, so be sure to state this in your discussion. You’ll need to know the current literature on your topic anyway, as this is part of your literature review section .

Step 3: Your Research’s Impact on Society

Inform your readers about the impact on society your research could have on it. For example, in the study about teachers’ opinions on cyberbullying, you could mention that your research will educate the community about teachers’ perceptions of cyberbullying as it affects student performance. As a result, the community will know how many teachers believe cyberbullying affects student performance.

You can also mention specific individuals and institutions that would benefit from your study. In the example of cyberbullying, you might indicate that school principals and superintendents would benefit from your research.

Step 4: Future Studies in the Field

Next, discuss how the significance of your research will benefit future studies, which is especially helpful for future researchers in your field. In the example of cyberbullying affecting student performance, your research could provide further opportunities to assess teacher perceptions of cyberbullying and its effects on students from larger populations. This prepares future researchers for data collection and analysis.

Discussing the significance of your research may sound daunting when you haven’t conducted it yet. However, an audience might not read your paper if they don’t know the significance of the research. By focusing on the problem statement and the research benefits to society and future studies, you can convince your audience of the value of your research.

Remember that everything you write doesn’t have to be set in stone. You can go back and tweak the significance of your research after conducting it. At first, you might only include general contributions of your study, but as you research, your contributions will become more specific.

You should have a solid understanding of your topic in general, its associated problems, and the literature review before tackling the significance of your research. However, you’re not trying to prove your thesis statement at this point. The significance of research just convinces the audience that your study is worth reading.

Finally, we always recommend seeking help from your research advisor whenever you’re struggling with ideas. For a more visual idea of how to discuss the significance of your research, we suggest checking out this video .

1. Do I need to do my research before discussing its significance?

No, you’re discussing the significance of your research before you conduct it. However, you should be knowledgeable about your topic and the related literature.

2. Is the significance of research the same as its implications?

No, the research implications are potential questions from your study that justify further exploration, which comes after conducting the research.

 3. Discussing the significance of research seems overwhelming. Where should I start?

We recommend the problem statement as a starting point, which reveals clues to the potential outcome of your research.

4. How can I get feedback on my discussion of the significance of my research?

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

How To Write A Dissertation Introduction

A Simple Explainer With Examples + Free Template

By: Derek Jansen (MBA) | Reviewed By Dr Eunice Rautenbach (D. Tech) | March 2020

If you’re reading this, you’re probably at the daunting early phases of writing up the introduction chapter of your dissertation or thesis. It can be intimidating, I know. 

In this post, we’ll look at the 7 essential ingredients of a strong dissertation or thesis introduction chapter, as well as the essential things you need to keep in mind as you craft each section. We’ll also share some useful tips to help you optimize your approach.

Overview: Writing An Introduction Chapter

• The purpose and function of the intro chapter
• Craft an enticing and engaging opening section
• Provide a background and context to the study
• Clearly define the research problem
• State your research aims, objectives and questions
• Explain the significance of your study
• Identify the limitations of your research
• Outline the structure of your dissertation or thesis

A quick sidenote:

You’ll notice that I’ve used the words dissertation and thesis interchangeably. While these terms reflect different levels of research – for example, Masters vs PhD-level research – the introduction chapter generally contains the same 7 essential ingredients regardless of level. So, in this post, dissertation introduction equals thesis introduction.

Start with why.

To craft a high-quality dissertation or thesis introduction chapter, you need to understand exactly what this chapter needs to achieve. In other words, what’s its purpose ? As the name suggests, the introduction chapter needs to introduce the reader to your research so that they understand what you’re trying to figure out, or what problem you’re trying to solve. More specifically, you need to answer four important questions in your introduction chapter.

These questions are:

• What will you be researching? (in other words, your research topic)
• Why is that worthwhile? (in other words, your justification)
• What will the scope of your research be? (in other words, what will you cover and what won’t you cover)
• What will the limitations of your research be? (in other words, what will the potential shortcomings of your research be?)

Simply put, your dissertation’s introduction chapter needs to provide an overview of your planned research , as well as a clear rationale for it. In other words, this chapter has to explain the “what” and the “why” of your research – what’s it all about and why’s that important.

Simple enough, right?

Well, the trick is finding the appropriate depth of information. As the researcher, you’ll be extremely close to your topic and this makes it easy to get caught up in the minor details. While these intricate details might be interesting, you need to write your introduction chapter on more of a “need-to-know” type basis, or it will end up way too lengthy and dense. You need to balance painting a clear picture with keeping things concise. Don’t worry though – you’ll be able to explore all the intricate details in later chapters.

Now that you understand what you need to achieve from your introduction chapter, we can get into the details. While the exact requirements for this chapter can vary from university to university, there are seven core components that most universities will require. We call these the seven essential ingredients . 

The 7 Essential Ingredients

• The opening section – where you’ll introduce the reader to your research in high-level terms
• The background to the study – where you’ll explain the context of your project
• The research problem – where you’ll explain the “gap” that exists in the current research
• The research aims , objectives and questions – where you’ll clearly state what your research will aim to achieve
• The significance (or justification) – where you’ll explain why your research is worth doing and the value it will provide to the world
• The limitations – where you’ll acknowledge the potential limitations of your project and approach
• The structure – where you’ll briefly outline the structure of your dissertation or thesis to help orient the reader

By incorporating these seven essential ingredients into your introduction chapter, you’ll comprehensively cover both the “ what ” and the “ why ” I mentioned earlier – in other words, you’ll achieve the purpose of the chapter.

Side note – you can also use these 7 ingredients in this order as the structure for your chapter to ensure a smooth, logical flow. This isn’t essential, but, generally speaking, it helps create an engaging narrative that’s easy for your reader to understand. If you’d like, you can also download our free introduction chapter template here.

Alright – let’s look at each of the ingredients now.

#1 – The Opening Section

The very first essential ingredient for your dissertation introduction is, well, an introduction or opening section. Just like every other chapter, your introduction chapter needs to start by providing a brief overview of what you’ll be covering in the chapter.

This section needs to engage the reader with clear, concise language that can be easily understood and digested. If the reader (your marker!) has to struggle through it, they’ll lose interest, which will make it harder for you to earn marks. Just because you’re writing an academic paper doesn’t mean you can ignore the basic principles of engaging writing used by marketers, bloggers, and journalists. At the end of the day, you’re all trying to sell an idea – yours is just a research idea.

So, what goes into this opening section?

Well, while there’s no set formula, it’s a good idea to include the following four foundational sentences in your opening section:

1 – A sentence or two introducing the overall field of your research.

For example:

“Organisational skills development involves identifying current or potential skills gaps within a business and developing programs to resolve these gaps. Management research, including X, Y and Z, has clearly established that organisational skills development is an essential contributor to business growth.”

2 – A sentence introducing your specific research problem.

“However, there are conflicting views and an overall lack of research regarding how best to manage skills development initiatives in highly dynamic environments where subject knowledge is rapidly and continuously evolving – for example, in the website development industry.”

3 – A sentence stating your research aims and objectives.

“This research aims to identify and evaluate skills development approaches and strategies for highly dynamic industries in which subject knowledge is continuously evolving.”.

4 – A sentence outlining the layout of the chapter.

“This chapter will provide an introduction to the study by first discussing the background and context, followed by the research problem, the research aims, objectives and questions, the significance and finally, the limitations.”

As I mentioned, this opening section of your introduction chapter shouldn’t be lengthy . Typically, these four sentences should fit neatly into one or two paragraphs, max. What you’re aiming for here is a clear, concise introduction to your research – not a detailed account.

PS – If some of this terminology sounds unfamiliar, don’t stress – I’ll explain each of the concepts later in this post.

#2 – Background to the study

Now that you’ve provided a high-level overview of your dissertation or thesis, it’s time to go a little deeper and lay a foundation for your research topic. This foundation is what the second ingredient is all about – the background to your study.

So, what is the background section all about?

Well, this section of your introduction chapter should provide a broad overview of the topic area that you’ll be researching, as well as the current contextual factors . This could include, for example, a brief history of the topic, recent developments in the area, key pieces of research in the area and so on. In other words, in this section, you need to provide the relevant background information to give the reader a decent foundational understanding of your research area.

Let’s look at an example to make this a little more concrete.

If we stick with the skills development topic I mentioned earlier, the background to the study section would start by providing an overview of the skills development area and outline the key existing research. Then, it would go on to discuss how the modern-day context has created a new challenge for traditional skills development strategies and approaches. Specifically, that in many industries, technical knowledge is constantly and rapidly evolving, and traditional education providers struggle to keep up with the pace of new technologies.

Importantly, you need to write this section with the assumption that the reader is not an expert in your topic area. So, if there are industry-specific jargon and complex terminology, you should briefly explain that here , so that the reader can understand the rest of your document.

Don’t make assumptions about the reader’s knowledge – in most cases, your markers will not be able to ask you questions if they don’t understand something. So, always err on the safe side and explain anything that’s not common knowledge.

#3 – The research problem

Now that you’ve given your reader an overview of your research area, it’s time to get specific about the research problem that you’ll address in your dissertation or thesis. While the background section would have alluded to a potential research problem (or even multiple research problems), the purpose of this section is to narrow the focus and highlight the specific research problem you’ll focus on.

But, what exactly is a research problem, you ask?

Well, a research problem can be any issue or question for which there isn’t already a well-established and agreed-upon answer in the existing research. In other words, a research problem exists when there’s a need to answer a question (or set of questions), but there’s a gap in the existing literature , or the existing research is conflicting and/or inconsistent.

So, to present your research problem, you need to make it clear what exactly is missing in the current literature and why this is a problem . It’s usually a good idea to structure this discussion into three sections – specifically:

• What’s already well-established in the literature (in other words, the current state of research)
• What’s missing in the literature (in other words, the literature gap)
• Why this is a problem (in other words, why it’s important to fill this gap)

Let’s look at an example of this structure using the skills development topic.

Organisational skills development is critically important for employee satisfaction and company performance (reference). Numerous studies have investigated strategies and approaches to manage skills development programs within organisations (reference).

(this paragraph explains what’s already well-established in the literature)

However, these studies have traditionally focused on relatively slow-paced industries where key skills and knowledge do not change particularly often. This body of theory presents a problem for industries that face a rapidly changing skills landscape – for example, the website development industry – where new platforms, languages and best practices emerge on an extremely frequent basis.

(this paragraph explains what’s missing from the literature)

As a result, the existing research is inadequate for industries in which essential knowledge and skills are constantly and rapidly evolving, as it assumes a slow pace of knowledge development. Industries in such environments, therefore, find themselves ill-equipped in terms of skills development strategies and approaches.

(this paragraph explains why the research gap is problematic)

As you can see in this example, in a few lines, we’ve explained (1) the current state of research, (2) the literature gap and (3) why that gap is problematic. By doing this, the research problem is made crystal clear, which lays the foundation for the next ingredient.

#4 – The research aims, objectives and questions

Now that you’ve clearly identified your research problem, it’s time to identify your research aims and objectives , as well as your research questions . In other words, it’s time to explain what you’re going to do about the research problem.

So, what do you need to do here?

Well, the starting point is to clearly state your research aim (or aims) . The research aim is the main goal or the overarching purpose of your dissertation or thesis. In other words, it’s a high-level statement of what you’re aiming to achieve.

Let’s look at an example, sticking with the skills development topic:

“Given the lack of research regarding organisational skills development in fast-moving industries, this study will aim to identify and evaluate the skills development approaches utilised by web development companies in the UK”.

As you can see in this example, the research aim is clearly outlined, as well as the specific context in which the research will be undertaken (in other words, web development companies in the UK).

Next up is the research objective (or objectives) . While the research aims cover the high-level “what”, the research objectives are a bit more practically oriented, looking at specific things you’ll be doing to achieve those research aims.

Let’s take a look at an example of some research objectives (ROs) to fit the research aim.

• RO1 – To identify common skills development strategies and approaches utilised by web development companies in the UK.
• RO2 – To evaluate the effectiveness of these strategies and approaches.
• RO3 – To compare and contrast these strategies and approaches in terms of their strengths and weaknesses.

As you can see from this example, these objectives describe the actions you’ll take and the specific things you’ll investigate in order to achieve your research aims. They break down the research aims into more specific, actionable objectives.

The final step is to state your research questions . Your research questions bring the aims and objectives another level “down to earth”. These are the specific questions that your dissertation or theses will seek to answer. They’re not fluffy, ambiguous or conceptual – they’re very specific and you’ll need to directly answer them in your conclusions chapter .

The research questions typically relate directly to the research objectives and sometimes can look a bit obvious, but they are still extremely important. Let’s take a look at an example of the research questions (RQs) that would flow from the research objectives I mentioned earlier.

• RQ1 – What skills development strategies and approaches are currently being used by web development companies in the UK?
• RQ2 – How effective are each of these strategies and approaches?
• RQ3 – What are the strengths and weaknesses of each of these strategies and approaches?

As you can see, the research questions mimic the research objectives , but they are presented in question format. These questions will act as the driving force throughout your dissertation or thesis – from the literature review to the methodology and onward – so they’re really important.

A final note about this section – it’s really important to be clear about the scope of your study (more technically, the delimitations ). In other words, what you WILL cover and what you WON’T cover. If your research aims, objectives and questions are too broad, you’ll risk losing focus or investigating a problem that is too big to solve within a single dissertation.

Simply put, you need to establish clear boundaries in your research. You can do this, for example, by limiting it to a specific industry, country or time period. That way, you’ll ringfence your research, which will allow you to investigate your topic deeply and thoroughly – which is what earns marks!

#5 – Significance

Now that you’ve made it clear what you’ll be researching, it’s time to make a strong argument regarding your study’s importance and significance . In other words, now that you’ve covered the what, it’s time to cover the why – enter essential ingredient number 5 – significance.

Of course, by this stage, you’ve already briefly alluded to the importance of your study in your background and research problem sections, but you haven’t explicitly stated how your research findings will benefit the world . So, now’s your chance to clearly state how your study will benefit either industry , academia , or – ideally – both . In other words, you need to explain how your research will make a difference and what implications it will have .

Let’s take a look at an example.

“This study will contribute to the body of knowledge on skills development by incorporating skills development strategies and approaches for industries in which knowledge and skills are rapidly and constantly changing. This will help address the current shortage of research in this area and provide real-world value to organisations operating in such dynamic environments.”

As you can see in this example, the paragraph clearly explains how the research will help fill a gap in the literature and also provide practical real-world value to organisations.

This section doesn’t need to be particularly lengthy, but it does need to be convincing . You need to “sell” the value of your research here so that the reader understands why it’s worth committing an entire dissertation or thesis to it. This section needs to be the salesman of your research. So, spend some time thinking about the ways in which your research will make a unique contribution to the world and how the knowledge you create could benefit both academia and industry – and then “sell it” in this section.

#6 – The limitations

Now that you’ve “sold” your research to the reader and hopefully got them excited about what’s coming up in the rest of your dissertation, it’s time to briefly discuss the potential limitations of your research.

But you’re probably thinking, hold up – what limitations? My research is well thought out and carefully designed – why would there be limitations?

Well, no piece of research is perfect . This is especially true for a dissertation or thesis – which typically has a very low or zero budget, tight time constraints and limited researcher experience. Generally, your dissertation will be the first or second formal research project you’ve ever undertaken, so it’s unlikely to win any research awards…

Simply put, your research will invariably have limitations. Don’t stress yourself out though – this is completely acceptable (and expected). Even “professional” research has limitations – as I said, no piece of research is perfect. The key is to recognise the limitations upfront and be completely transparent about them, so that future researchers are aware of them and can improve the study’s design to minimise the limitations and strengthen the findings.

Generally, you’ll want to consider at least the following four common limitations. These are:

• Your scope – for example, perhaps your focus is very narrow and doesn’t consider how certain variables interact with each other.
• Your research methodology – for example, a qualitative methodology could be criticised for being overly subjective, or a quantitative methodology could be criticised for oversimplifying the situation (learn more about methodologies here ).
• Your resources – for example, a lack of time, money, equipment and your own research experience.
• The generalisability of your findings – for example, the findings from the study of a specific industry or country can’t necessarily be generalised to other industries or countries.

Don’t be shy here. There’s no use trying to hide the limitations or weaknesses of your research. In fact, the more critical you can be of your study, the better. The markers want to see that you are aware of the limitations as this demonstrates your understanding of research design – so be brutal.

#7 – The structural outline

Now that you’ve clearly communicated what your research is going to be about, why it’s important and what the limitations of your research will be, the final ingredient is the structural outline.The purpose of this section is simply to provide your reader with a roadmap of what to expect in terms of the structure of your dissertation or thesis.

In this section, you’ll need to provide a brief summary of each chapter’s purpose and contents (including the introduction chapter). A sentence or two explaining what you’ll do in each chapter is generally enough to orient the reader. You don’t want to get too detailed here – it’s purely an outline, not a summary of your research.

Let’s look at an example:

In Chapter One, the context of the study has been introduced. The research objectives and questions have been identified, and the value of such research argued. The limitations of the study have also been discussed.

In Chapter Two, the existing literature will be reviewed and a foundation of theory will be laid out to identify key skills development approaches and strategies within the context of fast-moving industries, especially technology-intensive industries.

In Chapter Three, the methodological choices will be explored. Specifically, the adoption of a qualitative, inductive research approach will be justified, and the broader research design will be discussed, including the limitations thereof.

So, as you can see from the example, this section is simply an outline of the chapter structure, allocating a short paragraph to each chapter. Done correctly, the outline will help your reader understand what to expect and reassure them that you’ll address the multiple facets of the study.

Keep calm and carry on.

Hopefully you feel a bit more prepared for this challenge of crafting your dissertation or thesis introduction chapter now. Take a deep breath and remember that Rome wasn’t built in a day – conquer one ingredient at a time and you’ll be firmly on the path to success.

Let’s quickly recap – the 7 ingredients are:

• The opening section – where you give a brief, high-level overview of what your research will be about.
• The study background – where you introduce the reader to key theory, concepts and terminology, as well as the context of your study.
• The research problem – where you explain what the problem with the current research is. In other words, the research gap.
• The research aims , objectives and questions – where you clearly state what your dissertation will investigate.
• The significance – where you explain what value your research will provide to the world.

Significance of the Study Samples | Writing Tips

When you write a thesis , there is a section there that is allocated for the significance of the study. This article will provide different  significance of the study examples and will discuss tips on how to write this part.

Tips in Writing the Significance of the Study

Here are the tips that may be helpful when writing the significance of the study. These tips will tell you the basic components expected to be seen in the significance of the study content.

1. Refer to the Problem Statement

In writing the significance of the study, always refer to the statement of the problem. This way, you can clearly define the contribution of your study. To simplify, your research should answer this question, “What are the benefits or advantages of the study based on the statement of the problem?”

Start by explaining the problem that your study aimed to solve. For example, if you conducted a research study on obesity rates among elementary school students, you would start by explaining that obesity is a major health concern in the Philippines and discuss why it is important to find ways to address this issue.

2. Write it from General to Particular

Determine the specific contribution of your thesis study to society as well as to the individual. Write it deductively, starting from general to specific. Start your significance of the study broadly then narrow it out to a specific group or person. This is done by looking into the general contribution of your study, such as its importance to society as a whole, then moving towards its contribution to individuals like yourself as a researcher.

Discuss how your study fills a gap in the literature. If you conducted an experiment on the effects of a certain type of food on children, for example, you might start by explaining that no research has been done on this topic before. This section would also include a discussion about why your study is important.

Your problem statement might help you determine the unique contribution of your research. This can be accomplished by ensuring that the aim of the problem and the study’s objectives are identical. For instance, if your research question is “Is there a significant relationship between the use of Facebook Messenger and the performance of students in English spelling? “, you could write as one of the contributions of your study: “The study will identify common errors in spelling and grammar by Messenger users and recommend its appropriate use in a way that can improve performance in spelling.”

Here are some examples to help you draft your own introduction:

Title: Number of Clinical Internship Hours: A Determinant of Student’s Effectiveness and Skill  Acquisition in the Hospital Area for Velez College Students

Significance of the study.

The results of the study will be of great benefit to the following:

College of Nursing Dean . Data given will provide the dean with information on how the number of duty hours in a week affects the student’s academic and RLE performance. The results will enable the dean to improve the scheduling of RLE and different academic subjects. Data gathered will help the dean initiate collaboration among faculty and chairpersons to help plan the advancement of nursing education in relation to the new curriculum.

Clinical Instructors . The results of the study will help the clinical instructors evaluate the quality of care rendered by the nursing students, academic performance, attitude and skills acquired in relation to the number of hours given in a week. Results would also develop the clinical instructor’s teaching-learning and evaluating strategies in enhancing knowledge, skills and attitude to the students in the time frame given.

Students . This study will provide information regarding which time arrangement is effective: 8-hr of clinical internship from the 5-hr clinical internship with additional academic classes. This study will evaluate the academic performance, the student nurse’s attitude and approach, the skills learned in the clinical area, and the quality of care rendered in the given time frame. Data gathered will also help the students improve both academic and clinical performance.

Velez College . This study will improve the school in the development of nursing education. This study will foster new ways of enhancing knowledge, skills, and attitude, thus preparing globally-competitive nurses in the future. This study will also help in the advancement of school management, clinical leadership, and the teaching-evaluation approach.

Title: The Effectiveness of Isuzu’s Blue Power Technology in Fuel Efficiency of Diesel Engines

The generalization of this study would be a great contribution to the vast knowledge in relation to the brand awareness of Isuzu’s Blue Power Euro 4 Technology. Furthermore, the results of this investigation could be highly significant and beneficial for the following:

Current Customers

They refer to consumers that have already bought products from Isuzu. They are considered to be the main beneficiaries of the business. The findings of this study would provide them with adequate information about the product, most especially for those clients that have already bought units with the Blue Power Euro 4 Technology but have no idea of its benefits and advantages.

Potential Customer

They are the consumers that have not yet purchased this brand. This study aims to give them insights and overviews of the product and would help them choose the right variant to purchase.

They are the main beneficiaries of this study, which may help them to improve their marketing strategies. It would provide substantial data to the business that they could make use of in boosting their sales. Moreover, developing brand awareness will cater to more demands and loyalty in the future.

For they also play a vital role in the business and as consumers. This research would give them the idea that such private vehicles exist, which helps them to conserve energy rather than exploit it. Hence, giving back to the community and making it a better place to live.

Proponents of the Study

This refers to the students conducting the study. They will find self-fulfillment and gain knowledge and skills in this study. This study will help and inspire more researchers to be more innovative and creative in their future endeavors.

Future Researchers

This study will serve as a reference for researchers on the subject of research in the field of marketing. This will serve as a guide to further developing the research with the connection to the variables used.

The significance of a study is a key component of a strong scientific paper. By following these tips, you can create a clear and concise explanation of the importance of your work. I hope that these tips and samples will help you create a perfect Significance of the Study for your thesis. Apply these tips to prevent your mind from wandering aimlessly as you draft the significance of the study. It will allow you to focus on the next section of your thesis, helping you finish it on time. Good luck!

How to write the significance of the study in a thesis?

The introduction chapter of the thesis contains the section “significance of the study”. As the name clearly indicates, its primary purpose is to explain the primary contributions of the thesis. Thesis significance is essential in the introduction because it indicates the relevance of the work, potential outcomes and the major beneficiaries of the study. Ideally, a thesis significance should portray the following elements:

• General contribution of the study.
• Specific contribution and application of study.
• Grounds on which the study is based.
• Explain with logical reasons the benefits of the study.

The significance of the study is a way through which the researcher conveys to the reviewer how the thesis is unique. It could be for the reviewer of the thesis, peer review by an academician, publication on various platforms, or to apply for a research grant. A clear statement of the thesis significance and its contribution gives the reader information about the research purpose too.

Write an impactful and effective thesis with significance

For an impactful significance of the study section, try to answer the following questions:

• What are the implications of my study?
• Why is it important to carry out this research?
• How does my study influence the policymaking process?
• How is my study related to existing knowledge on the subject?
• What benefits does my study have for others in the concerned subject area or the public?
• What new perspectives does my study add to the concerned subject?
• How can better theoretical models be built by using my study?
• How would my study contribute to bridging the gaps in existing available research?
• How will my study change the existing way of life?

Ideally, the length of the significance of the study section should range between 200-500 words.

• Step 1: Identify the gaps in existing research. The gaps should be relatable and realistic or quantifiable. Explain these gaps in the form of a problem statement.
• Step 2: Explain how the thesis research will benefit. For instance, will it explain a topic or element on which barely any information is available?
• Step 3: Explain how the research will benefit the industry. For instance, if the thesis is concerned with an investigation of the manufacturing industry, what are the key takeaways for the industry that will help them improve their performance?
• Step 4: Explain how the investigation will benefit the government. For instance, will the government be able to implement the suggested model or framework? Will it influence the economy, public policy, or general public behaviour in any way?

How to maintain a good flow in the significance of the study section

The researcher can use the following methods to make the thesis significance of the study section impactful.

• The problem statement section acts as the foundation of the thesis significance of the study section. It should therefore be very strong and concise.
• Avoid writing vague statements. Rather the statements should be put in a very simple way.
• The flow of writing should be from general to particular i.e. covering the general contribution of study (the broad area) and then moving to the specific contribution (narrowing down).
• Avoid repetition of facts or statements.
• Avoid deviation from the subject/ area of study.
• Logical reasons should be added to justify the need for research.

Example of thesis significance of the study

Examining the need of adopting smart education in secondary education in India.

The thesis significance of the study section can be written as follows.

With the rapid growth in information and technology, the need for moving toward an IT-based education system is intensifying. In India, the limited use of smart technologies usage prevents students from improving their learning experience. Despite the growing number of studies on this problem, not much attention has been devoted to understanding the connection between smart education and educational development in India. This study focuses on bridging this gap in the existing literature by examining the contribution of smart education toward a superior learning experience for secondary school students.

This linkage of the IT sector with education would not only improve the education gaining experience of students but broadly would lead to the social development of the country. The prospect of increasing the accessibility of education along with creating a better learning experience would enable an improvement in the living standard. Further, the improvement in the learning experience of students would enable them to enhance their creativity level, have better interaction with teachers, and even gain better practical knowledge of aspects. This would help students strengthen their conceptual foundation. Thus, smart technology plays an undeniable role in socio-economic development and the life of students. This study will be significant in identifying all these aspects and help the government and secondary schools in upgrading their current policies of education and teaching for the socio-economic development of the country.

The significance of a study is its importance . It refers to the contribution(s) to and impact of the study on a research field. The significance also signals who benefits from the research findings and how.

Purpose of writing the significance of a study

A study’s significance should spark the interest of the reader. Researchers will be able to appreciate your work better when they understand the relevance and its (potential) impact. Peer reviewers also assess the significance of the work, which will influence the decision made (acceptance/rejection) on the manuscript. 

Sections in which the significance of the study is written

Introduction.

In the Introduction of your paper, the significance appears where you talk about the potential importance and impact of the study. It should flow naturally from the problem , aims and objectives, and rationale .

The significance is described in more detail in the concluding paragraph(s) of the Discussion or the dedicated Conclusions section. Here, you put the findings into perspective and outline the contributions of the findings in terms of implications and applications.

The significance may or may not appear in the abstract . When it does, it is written in the concluding lines of the abstract.

Significance vs. other introductory elements of your paper

In the Introduction…

• The problem statement outlines the concern that needs to be addressed.
• The research aim describes the purpose of the study.
• The objectives indicate how that aim will be achieved.
• The rationale explains why you are performing the study.
• The significance tells the reader how the findings affect the topic/broad field. In other words, the significance is about how much the findings matter.

How to write the significance of the study

A good significance statement may be written in different ways. The approach to writing it also depends on the study area. In the arts and humanities , the significance statement might be longer and more descriptive. In applied sciences , it might be more direct.

a. Suggested sequence for writing the significance statement

• Think of the gaps your study is setting out to address.
• Look at your research from general and specific angles in terms of its (potential) contribution .
• Once you have these points ready, start writing them, connecting them to your study as a whole.

b. Some ways to begin your statement(s) of significance

Here are some opening lines to build on:

• The particular significance of this study lies in the… 
• We argue that this study moves the field forward because…
• This study makes some important contributions to…
• Our findings deepen the current understanding about…

c. Don’ts of writing a significance statement

• Don’t make it too long .
• Don’t repeat any information that has been presented in other sections.
• Don’t overstate or exaggerat e the importance; it should match your actual findings.

Example of significance of a study

Note the significance statements highlighted in the following fictional study.

Significance in the Introduction

The effects of Miyawaki forests on local biodiversity in urban housing complexes remain poorly understood. No formal studies on negative impacts on insect activity, populations or diversity have been undertaken thus far. In this study, we compared the effects that Miyawaki forests in urban dwellings have on local pollinator activity. The findings of this study will help improve the design of this afforestation technique in a way that balances local fauna, particularly pollinators, which are highly sensitive to microclimatic changes.

Significance in the Conclusion

[…] The findings provide valuable insights for guiding and informing Miyawaki afforestation in urban dwellings. We demonstrate that urban planning and landscaping policies need to consider potential declines.

A study’s significance usually appears at the end of the Introduction and in the Conclusion to describe the importance of the research findings. A strong and clear significance statement will pique the interest of readers, as well as that of relevant stakeholders.

How to Write the Rationale of the Study in Research (Examples)

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

Table of Contents:

How to write a rationale for a research paper , how do you justify the need for a research study.

• Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

• Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
• Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

• A summary of conclusions from your review of the relevant literature
• What is currently unknown (gaps in knowledge)
• Inconclusive or contested results  from previous studies on the same or similar topic
• The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

• Did earlier studies try but failed to measure/identify a specific phenomenon?
• Was earlier research based on incorrect conceptualizations of variables?
• Were earlier studies based on questionable operationalizations of key concepts?
• Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

• Have recent changes in the studied problem made previous studies irrelevant?
• Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

• Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

Two important issues constrain the neighborhood effects literature. First, most prior research examining neighborhood effects on aggression and self-reported violence uses a point in time (i.e., cross-sectional) estimate of neighborhood disadvantage even though the duration of exposure to neighborhood disadvantage varies between families. Second, neighborhood effects may be understated due to over-controlling for family socioeconomic conditions. Both limitations suggest that prior research may be underestimating neighborhood effects, which impacts research on the invariance thesis and explanation of ethnoracial differences.

The sample is drawn from the restricted use Future of Families and Child Well-being study. Data to measure youth’s exposure to neighborhood disadvantage is drawn from birth through age 9, with dependent variables measured at age 15. We estimate marginal structural models (MSM) with inverse probability of treatment weights (IPTW.

The results support hypotheses, indicating that the duration weighted measure of neighborhood disadvantage is more strongly associated with aggression and self-reported violence than the point in time, and that it accounts for a larger share of the ethnoracial differences.

Conclusions

The findings provide a clear image of the consequences of long-term exposure to neighborhood disadvantage for aggression and violence. They suggest that criminologists addressing neighborhood effects should attempt, when feasible, to document and model the duration of exposure to neighborhood disadvantage. They are also consistent with and add to a growing literature addressing MSM modeling with IPTW weights.

Introduction

The literature documenting neighborhood effects on aggression and self-reported violence is constrained by at least two issues. First, prior studies likely understate the magnitude of neighborhood effects because they employ a point in time estimate of neighborhood disadvantage. As such, those studies do not capture cumulative, longer-term consequences of exposure to neighborhood disadvantage. Analytically, this means that adolescents experiencing short-term exposure to neighborhood disadvantage are treated as conceptually equivalent to those who have been exposed across a larger segment of their lives, particularly during childhood. Previous research finds that neighborhood effects on health, sex risk, educational, and life course outcomes are more pronounced when neighborhood effects are weighted to reflect the duration of the exposure (Kravitz-Wirtz 2016a , b ; Wodtke 2013 ; Wodtke et al. 2011 ). However, prior research has not addressed criminological outcomes such as self-reported violence or focused more specifically on aggression. Second, neighborhood effects research has characteristically controlled for family socioeconomic characteristics, especially family structure and income, for instance (see Baumer and South  2001 ; Brewster 1994 ; Browning et al. 2004 ; Cleveland and Gilson 2004 ; Kim 2010 ; Santelli et al. 2000 ). Wodtke et al. ( 2011 ) illustrate that these conventional regression models overcontrol for family SES and introduce collider–stratification bias (Elwert and Winship 2014 ; Greenland 2003 ). Wodtke et al. ( 2011 ) advocate utilizing marginal structural modeling (MSM) with inverse probability of treatment weights (IPTW), which corrects for the tendency to underestimate neighborhood effects.

Utilizing MSM with IPTW is also important when addressing ethnoracial differences in violent behavior. Shaw and McKay ( 1942 ) were among the first to document racial and ethnic differences in delinquency and to argue that they are a function of disadvantaged neighborhood conditions. Sampson and Wilson ( 1995 ) extend this logic and propose the racial invariance thesis, which hypothesizes that racial/ethnic disparities in violence reflect relative group-specific exposure to neighborhood structures, particularly concentrated disadvantage. Research addressing ethnoracial differences is built up on “point in time” (i.e., cross-sectional) measures of concentrated disadvantage, even though this approach makes the dubious assumption that each group’s length of exposure to disadvantage is roughly equivalent. This is a critical limitation. As Sharkey and Elwert ( 2011 ) document, many African American youth reside in disadvantaged neighborhoods their entire life. Sometimes this pattern is inter-generational within families, and both are likely true to an extent for other groups of color including multiracial and Hispanic families. This suggests that the developing literature on duration weighted modeling may have substantial relevance for understanding ethnoracial differences in aggression and violence.

In this paper, we contribute to the literature on violence by utilizing MSM and IPTW methods to inform a comparison between duration weighted and point in time estimates of concentrated neighborhood disadvantage. Drawing data from the Future of Families and Child Well-being study, which provides a national sample of adolescents who have been followed since birth, we test the hypothesis that duration weighted disadvantage exerts a stronger effect on primary caregiver’s reports of aggressive behavior and youth’s self-reported violence than the point in time estimate, and that it explains a greater percent of ethnoracial differences in those outcomes. We find support for both hypotheses. The findings carve a clearer image of the consequences of longer-term exposure to neighborhood disadvantage for aggressive and violent behaviors, and the explanation of ethnoracial differences. In the next sections, we review foundational literature examining neighborhood, duration weighted measurement, ethnoracial differences, and provide additional background on MSMs and IPTW.

Neighborhood Effects and Ethnoracial Disparities

The literature documenting neighborhood effects emerged in earnest in the mid-1980's (see Simcha-Fagan and Schwartz 1986 ) and early 1990’s, and “has become something of a cottage industry in the social sciences” (Sampson et al. 2002 : p 444). Although important methodological issues remain, researchers have focused inquiry on whether neighborhoods matter, rather than on the question of how they matter (Sharkey 2014 ). In particular, researchers have in general neglected the conceptual difference between episodic and long-term residence in disadvantaged neighborhoods (Sharkey and Elwert 2011 ).

The majority of research on ethnoracial disparities in violent behavior is framed within the social disorganization tradition. For instance, Shaw and McKay ( 1942 ) argue that high rates of delinquency among ethnoracial groups relative to Whites is a product of segregation and economic inequality (Sampson and Wilson 1995 ; Sampson et al. 2018 ; Wilson 1987 , 1996 , 2009 ), and is reflected by racialized economic disadvantage (Krivo et al. 2009 ; Peterson and Krivo 2010 ). As Graham ( 2018 : 450–1) eloquently summarizes with respect to Black and White youth:

“The typical Black adolescent in America lives in a very different type of neighborhood, attends a very different type of school, and is embedded in a very different type of social network, than her White counterpart. Almost a half century after the civil rights era, these differences remain poignant ... Minority children tend to grow up in different social environments than their White counterparts. This observation, while self-evident, is nevertheless important and, perhaps, too infrequently made.”

In addition, cultural adaptation and legal cynicism reinforce the use of aggression and violence as a means of conflict resolution in impoverished neighborhoods, which further places youth at risk (Anderson 1999 ; Heimer 1997 ; Stewart et al. 2006 ; Stewart and Simons 2006 ).

Our hypothesis is that the differences in social worlds experienced by White, Black, Multiracial, and Latinx youth are directly relevant for understanding ethnoracial differences in aggression and violence. Official (UCR) and self-reported data point to race differences, but the magnitude varies by source. Compared with non-Hispanic White adolescents, it is well documented that Black youth are over-represented in arrests for serious index crimes, particularly violent crimes (Hawkins et al. 2000 ), while Asian youth are under-represented. UCR data do not include the ethnicity of arrestees, thus they are less useful for investigating Hispanic involvement. Ethnoracial differences are less pronounced in self-report surveys for a variety of reasons, but Black-White difference is nevertheless evident, particularly in violence and more serious offenses (Morenoff 2005 ). Self-report studies also reveal that Hispanics are over-represented in violence relative to Whites (McNulty and Bellair 2003b ). Adolescents of Asian descent are under-represented relative to Whites (McNulty and Bellair 2003b ).

Findings from recent contextual studies indicate that ethnoracial disparities in violence are reduced once concentrated disadvantage is held constant (Bellair and McNulty 2005 ; Lauritsen and White 2001 ; McNulty and Bellair 2003a , b ; Sampson et al. 2005 ), which is consistent with the racial invariance thesis (Sampson et al. 2018 ). This has created ambiguity in the literature because concentrated disadvantage does not fully explain ethnoracial disparities in violence in many studies, which some argue contradicts the invariance thesis (Unnever 2018 ). This has led to calls for a distinct theory to address the unique causes of crime in poor, African American neighborhoods, and we presume other communities of color, such as a high incidence of police contact and experiences of discrimination (Unnever et al. 2016 ). Yet, this may be a false dichotomy, because point in time measurement of neighborhood disadvantage may not fully capture historic or more contemporary discrimination that is rooted in neighborhood structures (Sampson et al. 2018 ). Indeed, most studies employ point-in-time (i.e., cross-sectional) indicators of disadvantage, which may underestimate neighborhood effects relative to duration weighted measurement (see Carlson et al. 2022 ).

Duration Weighted Neighborhood Disadvantage and Ethnoracial Disparities

Ambiguous findings pertaining to the role of neighborhoods in producing ethnoracial disparities in violence do not account for the length of one’s life spent residing in disadvantaged neighborhoods. Most importantly, we hypothesize that the failure to account for cumulative exposure to neighborhood disadvantage throughout childhood and adolescence may lead to underestimation of neighborhood effects. Some research assesses the critical distinction between point-in-time or cross-sectional measurement of neighborhood disadvantage and duration weighted or cumulative exposure to neighborhood disadvantage. One study suggests that point in time measurement is a reasonable proxy for duration weighted measurement (Kunz et al. 2003 ). Most studies (Kravitz-Wirtz 2016a , b ; Wodtke 2013 ), however, document significant variation in youth exposure to neighborhood disadvantage over time (e.g., Timberlake 2007 ; Quillian 2003 ), and report that incorporating variation in exposure significantly improves prediction and explanation of self-rated health, smoking initiation, sex risk behavior, health inequalities, high school graduation, reading and math test scores, and adolescent parenting (Carlson et al. 2022 ; Hicks et al. 2018 ; Jackson and Mare 2007 ; Quillian 2003 ; Timberlake 2007 ; Wodtke et al. 2011 ). Although the aforementioned studies indicate support for duration weighted measurement of neighborhood disadvantage, there is very limited research that includes criminological outcomes. In particular, there are no studies to our knowledge focusing specifically on youth aggression and self-reported violence.

Disadvantaged neighborhoods have fewer institutional resources, such as quality schools, recreational activities, child care, medical facilities, and employment opportunities (Leventhal and Brooks-Gunn 2000 ). The dearth of institutional resources is likely to undermine children and adolescent’s social bonds to prosocial institutions such as school (Hirschi 1969 ). Adolescents residing in disadvantaged neighborhoods often experience distinctive cultural milieus and role models (Akers 1998 ), and may observe economic marginality among residents that leads them to conclude that their own future opportunities are limited (Bellair and Roscigno 2000 ). Economic deprivation, blighted institutional resources, and limited educational or employment opportunities may weaken the constraints and opportunity costs that impede risky behavior (Borowsky et al. 2009 ; Edin and Kefalas 2005 ).

The distinction between point-in-time exposure and cumulative exposure is critical because the neighborhood mechanisms that produce delinquent behavior may be more fundamental when experienced over a longer duration. As Sharkey ( 2014 : p 567) poignantly describes:

“It is natural to think that the residential environment surrounding children will have a greater influence on their lives if they are in the same environment over years or decades. Only recently, however, has the dimension of time entered into the empirical literature on neighborhood effects.”

Sharkey ( 2014 ) further points out that in the context of Wilson ( 1987 ) and Massey and Denton’s ( 1993 ) literature defining work, duration of exposure to disadvantaged residential environments is a critical dimension, yet that component is rarely addressed in most research. Due in part to discriminatory housing practices and residential segregation, African American, Multiracial, and Hispanic youth are more likely than Whites (and Asians) to experience generational exposure to concentrated neighborhood disadvantage (Lichter et al. 2016 ; Sharkey 2013 ; Timberlake 2007 ). Because a duration-weighted neighborhood disadvantage index captures adolescents that may have spent their entire lives exposed to the extremes of concentrated disadvantage, it is likely to yield better explanation of ethnoracial disparities.

An additional limitation of previous research is that time-varying factors, like family structure and socioeconomic status (SES), are treated as control variables that are unique relative to the neighborhood effect. However, time-varying confounders are in part outcomes of living in a disadvantaged residential context, and could bias estimates of neighborhood effects downward. This may introduce collider-stratification bias (Elwert and Winship 2014 ; Greenland 2003 ) due to joint associations with unobserved confounders that are themselves related to youth violence, and prior treatment to neighborhood disadvantage and violence (Elwert and Winship 2014 ; Greenland 2003 ; Wodtke et al. 2011 ). Time-varying factors may also mediate the association between neighborhood disadvantage and youth violence. Although including time-varying controls in regression models may produce downwardly biased estimates of neighborhood effects, excluding these variables may result in overestimation of neighborhood effects. Indeed, factors like family structure and SES also affect the length of youths’ exposure to neighborhood disadvantage (for a review, see Carlson et al. 2014 ).

Data and Methods

We address these issues with data drawn from the Future of Families and Child Well-Being Study (FFCWS). FFCWS is a longitudinal cohort study of 4,898 children born between 1998 and 2000 in 20 large U.S. cities, with an oversample of nonmarital births. Interviews in the hospital with mothers and fathers (or primary caregivers) at the child’s birth comprise the baseline, Wave 1 data. Follow ups are conducted when children reach age 1 (Wave 2), 3 (Wave 3), 5 (Wave 4), 9 (Wave 5), and 15 (Wave 6). Phone interviews with parents are conducted when the children are ages 1 (Wave 2), 3 (Wave 3), and 5 (Wave 4), and in-home assessments of children’s home environments are also conducted at ages 3 (Wave 3), 5 (Wave 4), 9 (Wave 5), and 15 (Wave 6). US census tract data are matched to the FFCWS at each wave because they have been used extensively to estimate neighborhood-level effects in prior research (Coulton et al. 2001 ; Krieger et al. 2003 ). Indicators of neighborhood disadvantage are drawn from the 2000 US Census through Wave 5, and the 2010 US Census and the 2015 American Community Survey 5-year averages are used at Wave 6.

The analysis is restricted to youth with complete data through Wave 6 because that is the year we measure the dependent variables. The sample is further delimited to youth who were identified by their parents as multiracial, non-Hispanic Black, non-Hispanic White, non-Hispanic Asian, or Hispanic. The very small number of youth (i.e., 40) who did not fit those categories are dropped due to limited statistical power. Of the original 4,898 children whose mothers participated in the baseline interview, 3,404 completed the Wave 6 interview when the youth were 15 years old. Missing information on parents’ income and work hours contributed the most to attrition across waves. Of the 3,404 youth who participated in the Wave 6 interview, 3,360 cases had complete information on parent/guardian reports of youths’ aggressive behavior and 3,381 had complete information on youths’ self-report of violent behavior. Missing information for independent and control variables at each wave was replaced using multiple imputation with chained imputations in Stata 15. We used Von Hippel ( 2020 ) program “how_many_imputations” in Stata to estimate the number of imputations needed for efficient estimation of standard errors. The program provides a recommended number of imputations such that standard errors for estimates do not change significantly with additional imputations. The results indicated that 10 imputed data sets were likely sufficient. As we describe in more detail below, missing data is addressed in part by employing a censoring weight that upweights cases with a greater likelihood of attrition.

Two dependent variables are analyzed in this study. The p rimary caregiver report of youth aggressio n is a summary scale of primary caregivers’ responses to 11 items from the child behavior checklist (CBCL). The items reflect whether the child is aggressive in different contexts. The items were completed by the primary caregiver when the youth were fifteen years old. Examples of items include whether the child argues a lot, is cruel to or bullies other children, destroys things, and gets into fights with and/or physically attacks other children. Response options for each item include: 0 = not true; 1 = sometimes true; 2 = always true. The scale reflects the mean level of involvement across each item.

The second dependent variable is y outh’s self-report of violent behavio r at age 15. Four items are included: getting into a serious physical fight, hurting someone badly enough to need medical care, using or threatening to use a weapon, and taking part in a group fight. Response categories range from never, 1 or 2 times, 3 or 4 times, or 5 or more times (coded 0 to 3, respectively). Self-reported violence is measured as the mean involvement across those items.

Ethnoracial identity is represented by a set of dummy variables. The variables distinguish multiracial, non-Hispanic Black, Hispanic, non-Hispanic Asian youth from non-Hispanic White youth. White youth comprise the reference category.

Neighborhood disadvantage is a composite index of seven indicators at the census-tract level, including (1) percentage of residents over age 16 who are unemployed, (2) percentage of households below the federal poverty threshold, (3) percentage of female-headed households with minor children, (4) percentage of adults over age 25 without a high school degree, (5) percentage of properties that are vacant, (6) percentage of residents who are non-White, and (7) median household income (reverse coded). Not all studies include percent non-White in the calculation of concentrated disadvantage. It is included here to capture the effect of historic discrimination, which Sampson ( 2012 ) argues is rooted in contemporary neighborhood structure. Principal component analysis identified a single common factor among the indicators and a composite score for each. Footnote 1 Each indicator of disadvantage is then standardized (i.e., represented as z scores) using the national census-tract average and standard deviation and then combined.

We then divided census tracts into quintiles based on the national distribution of the composite neighborhood disadvantage measures to create an ordinal measure of neighborhood disadvantage at age 9 that ranged from 1 = least disadvantaged to 5 = most disadvantaged. By creating an ordinal measure of neighborhood disadvantage we can more parsimoniously predict treatment and construct probability of treatment weights. The use of a continuous measure of disadvantage would likely necessitate the estimation of thousands of models for each disadvantage score. To construct duration of exposure to neighborhood disadvantage through age 9 , we took the average of neighborhood disadvantage across the five waves up to and including wave 5 (age 9).

To explain ethnoracial disparities in youth aggression and violence, and to demonstrate the utility of measuring duration-weighted exposure to disadvantage, models alternately and collectively include a measure of neighborhood disadvantage at age 9 (Wave 5) and duration-weighted exposure to neighborhood disadvantage . Because duration-weighted exposure is an average composite of exposures to neighborhood disadvantage, direct comparisons of effect magnitude can be made between proximal exposure to disadvantage at age 9 and long-term exposure as indicated by the duration-weighted measure. The means of the neighborhood disadvantage measures are statistically indistinguishable, yet readers should exercise some caution when comparing coefficients because small differences in the distributions could complicate the comparison. Although measuring neighborhood disadvantage up to age 9 establishes temporal ordering with respect to the outcomes, it may result in underestimation of neighborhood effects. However, a supplemental model (not shown) that substituted a measure of neighborhood disadvantage (i.e., point in time) at age 15 (Wave 6) did not produce substantively different results.

Control Variables

We control for a set of time-invariant and time-varying confounders in our models. Time-invariant baseline controls include youth female (1 = female), mother’s age at youth's birth (in years), mother U.S. born (1 = yes), youth born outside of marriage (1 = yes), and mother’s education (1 = less than high school, 2 = high school or equivalent, 3 = some college or technical degree, 4 = college or advanced degree). Five time-varying socioeconomic confounders were assessed at each wave and are included in the estimation of the marginal structural and IPTW models. Family structure is assessed with dummy variables distinguishing two-parent biological family (reference), single mother living with relatives or alone, mother–stepfather family, and other family arrangements. Two-parent biological families were defined as a child living with both biological parents, either cohabiting or married. We controlled for household income measured in dollars to assess time-varying aspects of family socioeconomic status (SES). Parent work hours is a continuous measure indicating the number of hours the parent worked; participants not in the labor force were coded 0. Father’s work hours are used in limited cases when the child resides with the father only, and mother’s work hours are used in all other cases. Last, residential mobility (1 = yes) between waves is included to capture whether respondents moved in between waves.

Analytic Strategy

Marginal structural models (MSM) (Fewell et al. 2004 ) are used to assess the role of exposure to neighborhood disadvantage in explaining youths’ aggressive and violent behavior, including ethnoracial differences. We choose MSM for our analyses because MSM produces more valid estimates in situations when an explanatory time-varying variable – in this instance exposure to neighborhood disadvantage – may be reciprocally related to time-varying confounders – like family SES. MSM creates a pseudo-population where time-varying explanatory variables and time-varying confounders are unassociated with each other (Do et al. 2013 ). The models are run in two stages. In the first stage, we construct an inverse probability of treatment weight (IPTW) for youths’ probability of exposure to their actual neighborhood disadvantage quintile at Wave k . This probability is calculated based on time-varying and time-invariant predictors of exposure to neighborhood disadvantage. In Stage 2, the IPTW is used to adjust regression estimates predicting aggression and violence.

To construct the IPTW, we used data from the first five waves of the FFCWS among youth in our analytic sample. The IPTW is presented in Eq.  1 .

f{*} is the conditional probability density function, A ( k ) is the time-varying treatment at Wave k , A ( k – 1) is previous treatment history up to wave ( k – 1), and \(\underline{L}(k)\) represents the history of time-dependent confounders. Estimation of the IPTW includes information on youths’ neighborhood quintile at baseline and at Wave ( k – 1), time-invariant baseline covariates, and information on time-varying covariates at Wave k , Wave ( k – 1), and baseline.

We calculate a stabilized IPTW to reduce variability and non-normality in the estimate. Stabilized weights have smaller variance, a mean of around 1, and are approximately normally distributed (Robins et al. 2000 ). Using notation from Fewell et al. ( 2004 ), we calculate the stabilized IPTW as follows:

The numerator is a constrained version of the predicted probability of treatment (i.e., exposure to actual neighborhood disadvantage quintile) that includes neighborhood treatment at Wave k, Wave ( k – 1), and baseline measures of covariates only L (0). It can be interpreted as the subject’s probability of experiencing their treatment history up to Wave k given baseline values of controls (Do et al. 2013 ). The denominator is the probability of treatment at Wave k given time-varying covariates and baseline controls.

To partially account for the possibility of nonrandom sample attrition, we multiply the stabilized IPTW at each wave of observation by a censoring weight which estimates the inverse probability of dropping out of the study at any particular wave as predicted by time-invariant and time-varying variables. Table 1 displays summary statistics for the stabilized IPTW and censoring weight.

We conduct our analysis in two steps. First, we establish the utility of the MSM by comparing estimates of the association of exposure to neighborhood disadvantage with caregivers’ reports of youth aggression and youths’ self-reported violence across three models – 1) unadjusted bivariate generalized linear model (GLM) regression (gamma distribution); 2) multivariate GLM regression (gamma) with time-invariant and time-varying controls, and 3) IPTW adjusted multivariate gamma GLM regression (gamma) with time-invariant controls. Analyses of aggressive and violent behaviors are conducted using GLM (gamma) given the continuous, positively skewed distribution of scores for aggressive and violent behavior and a high variance relative to the scale mean. Given that we assess the dependent variables at only one point in time (age 15), values for time-varying variables and the IPTW are calculated as the average value of these variables across waves. To establish temporal order, all time-varying variables, including neighborhood disadvantage and all confounders, as well as the IPTW are assessed only through Wave 5 (age 9).

In the second step we use GLM regression (gamma) and the KHB decomposition method (Breen et al. 2013 ) to examine how exposure to neighborhood disadvantage mediates the association of ethnoracial identity with aggressive and violent behaviors. As described in the measures section, two measures of neighborhood disadvantage in our models – a point-in-time estimate of neighborhood disadvantage at age 9 and a duration-weighted measure of exposure to neighborhood disadvantage through age 9. We include both measures to compare their association with aggression and self-reported violence. Both variables are measured on the same scale, with similar means and standard errors that are statistically indistinguishable ( p  > 0.05). Thus, the coefficients are directly comparable, but with caution. In the first regression model, we examine the association of ethnoracial identity with youths’ aggressive/violent behaviors. In Models 2 through 4, we add the two measures of neighborhood disadvantage separately and then jointly. In Model 5, we include background confounders of the association between neighborhood disadvantage and the outcomes.

Descriptive Statistics

Table 2 presents descriptive statistics for the full sample in the first column and the ethnoracial subgroups in columns 2–6. Non-Hispanic Black children (47%) comprise the largest share of the sample, followed by Hispanics (20%), non-Hispanic Whites (17%), and those who identify as multiracial (15%). Non-Hispanic Asian youths are under-represented in the FFCWS with only 40 children in the sample. Consistent with the literature on violence, primary caregiver reports of aggression and the youths’ self-reported violent behavior are relatively rare within the sample. The scale mean of 0.27 on the primary caregiver report of aggression indicates that about 27% of youth behaved aggressively. Among youth, the mean score for violent behavior (0.16) indicates that only 16% of the youth engaged in any of the violent behaviors, on average. There is significant variation in aggression and violent self-reports among ethnoracial subgroups. Youth who identify as multiracial and non-Hispanic Black evidence a significantly higher score on primary caregivers’ reports of aggressive behavior compared to non-Hispanic White children. Hispanic and Asian youth are statistically similar to non-Hispanic Whites. Regarding youths’ self-reports of violent behavior, multiracial, Black, and Hispanic youth report engaging in more violence than non-Hispanic White youth. Asian youth are statistically similar to non-Hispanic Whites.

On average, youths in the sample reside in contexts that are neither extremely disadvantaged nor advantaged, experiencing levels between those polar extremes (i.e., 3.102 out of 5). The neighborhood disadvantage means also vary based on the duration weighted or point in time (i.e., age 9). Non-Hispanic White and Asian youth are at the lowest risk of longer-term exposure to neighborhood disadvantage, and evidence lower levels of neighborhood disadvantage at age 9, compared to multiracial, Black, and Hispanic youth. Duration weighted exposure is especially pronounced for non-Hispanic Blacks and Hispanics.

Youths’ biological sex is roughly evenly split with females comprising about 49% of the sample, and there are slightly more males than females in each ethnoracial group except Asian. Non-Hispanic White and Asian children are significantly less likely to have been born to younger mothers, or to have been born outside of marriage, compared to the other ethnoracial groups. Most mothers were born in the U.S. The exception is Hispanic mothers, 40% of whom are foreign born. Roughly 76% of the sample is born outside of marriage, reflecting the sampling design of the FFCWS. Educational attainment among the mothers is somewhat constrained, with just under a third of mothers attaining less than high school and roughly the same proportion finishing high school. About 25% have attained some college with about 1 in 10 completing a college or graduate degree. Non-Hispanic White and Asian mothers are most likely to be college graduates. At the other extreme, multiracial (29%), Black (32%), and especially the mothers of Hispanic children (50%) are significantly more likely than White mothers (13%) to have less than a high school degree.

Over half of the families in the data are led by single mothers, just under one third are two-parent biological, and 15% are mother-stepfather, with a small fraction of other family types. Among the ethnoracial subgroups, non-Hispanic White and Asian children are significantly more likely to live in two biological parent families, whereas multiracial (59%), Black (63%), and Hispanic children (49%) are significantly more likely to be in single parent households compared to their White and Asian counterparts.

The typical household earns just over $41,000, and mothers work about 25 h per week on average. There is marked variation among the subgroups, with Asian and White households earning over twice the income relative to non-Hispanic Black and Hispanic, with multi-racial households earning somewhat, but not substantially higher wages relative to non-Hispanic Black and Hispanic households. Parent’s work hours do not vary markedly across subgroups, although Hispanic mothers work the fewest number of hours. Multiracial and non-Hispanic Black youth are most likely to have moved between waves, followed by Hispanics, non-Hispanic Whites and Asians.

Multivariate Models

Table 3 illustrates the consequences of failing to properly account for reciprocity in the relationships of time-varying confounders with neighborhood disadvantage. In a bivariate GLM (gamma) model, the duration weighted measure of neighborhood disadvantage exerts a positive and significant effect on aggressive behavior, but the effect dissipates and is not significant in the multivariate GLM (gamma) regression when time-invariant and time-varying variables are included as statistical controls. This indicates that when the IPTW weight is not utilized, the effect of duration weighted disadvantage is underestimated. However, once the stabilized IPTW is incorporated into the model, the duration weighted effect is positive and significant, indicating the importance of the length of time exposed to disadvantage and its role in shaping aggressive behavior by age 15. A similar pattern is observed when the lens is shifted towards youth’s self-reported violence, although the effect of duration weighted exposure to neighborhood disadvantage remains significant without invoking the stabilized IPTW.

Primary Caregiver Reports of Youth Aggression

Table 4 regresses primary caregiver reports of aggression (age 15) on ethnoracial group and neighborhood disadvantage. Model 1 highlights the baseline levels of aggressive behavior by ethnoracial identity. It indicates that Black children exhibit significantly more aggressive behavior compared to their non-Hispanic White counterparts. Multiracial, Hispanic, and Asian youth evidence statistically similar levels of involvement relative to non-Hispanic Whites.

Model 2 incorporates duration-weighted exposure to neighborhood disadvantage, which has the expected positive, significant effect on adolescent aggression. Importantly, Model 2 indicates that the disparity in aggressive behavior between White and Black adolescents is reduced to non-significance, reflecting the relatively longer-term exposure of the latter to neighborhood disadvantage compared to White children (see Table  2 ). The Hispanic-White disparity is suppressed in Model 1, as Model 2 reveals significantly lower levels of aggression among Hispanic youth (relative to White) when duration weighted exposure is controlled. In Model 3, we incorporate the point-in-time measure of neighborhood disadvantage, which exerts a significant, positive effect on aggressive behavior. It is also noteworthy that the point-in-time measure does not fully explain the heightened aggression among Black adolescents relative to White adolescents.

In Model 4, the duration weighted disadvantage measure is contrasted directly with the point in time measure. The results reveal that the duration weighted measure retains significance, while the point in time measure is zero. Variance inflation factor (VIF) estimates using OLS regression reveal little evidence of multicollinearity between these measures of disadvantage (VIF = 3.4). This indicates that the duration weighted measure, which reflects longer term exposure to disadvantaged contexts, has greater explanatory power than the point in time estimate and that point in time estimates are not proxies for measures of duration of exposure to disadvantage. Note as well that the difference in coefficients between the duration-weighted and point-in-time measures in Model 4 are statistically different ( p  < 0.01), lending additional evidence that duration weighted exposure better captures the realities of the consequences of longer term exposure to neighborhood disadvantage relative to cross-sectional measures.

Model 5 includes the remaining time-invariant control variables along with duration weighted exposure to neighborhood disadvantage. The latter retains a significant, positive effect and the Black effect remains zero. We note, however, consistent with recent research, that Hispanic youth evidence a lower risk of aggressive behavior than White youth, an effect that is suppressed by duration-weighted exposure to neighborhood disadvantage. Control variables have expected effects on aggression, but do not explain away the effect of duration weighted disadvantage on aggressive behavior. Females are less involved than males. Greater maternal educational attainment also exerts a constraint. In contrast, youth born outside of marriage, to younger mothers, and to U.S. born mothers are more likely to engage in aggressive behavior at age 15. Overall, the findings indicate support for the hypothesis that longer-term exposure to concentrated disadvantage is more consequential for Black and Hispanic youth (relative to White) than is point in time exposure.

Youth Self-reports of Violent Behavior

Table 5 presents GLM (Gamma) regressions of youth self-reports of violent behavior on ethnoracial identity and neighborhood disadvantage. Model 1 shows that Multiracial, Black, and Hispanic adolescents evidence significantly more involvement in violence compared to non-Hispanic white youth. Asian youth are statistically similar to their white counterparts. Model 2 incorporates duration weighted exposure to neighborhood disadvantage, which has a significant effect ( p  < 0.001) on adolescent self-reported violence. The Hispanic-White disparity in violence involvement is reduced in magnitude and to non-significance, whereas the Multiracial and Black coefficients have been reduced substantially but remain significant.

Model 3 in Table  5 incorporates point-in-time neighborhood disadvantage at age 9, which has a significant, positive effect on violent behavior. Ethnoracial disparities in violent behavior compared to Whites remain significant. Compared to Model 1 the Multiracial, Black, and Hispanic coefficients are reduced but not to the extent evidenced in Model 2, which included duration weighted exposure to neighborhood disadvantage. In Model 4, the duration weighted disadvantage measure is contrasted directly with the point in time measure. The latter is zero and not significant, whereas duration weighted exposure retains a significant positive effect on violence. This indicates that prolonged exposure to neighborhood disadvantage has greater explanatory power. Importantly, the effect of duration-weighted exposure is significantly larger than the point-in-time coefficient in Table  5 , Model 4 ( p  < 0.001), which again suggests that duration-weighted exposure better captures the consequences of longer term exposure to neighborhood disadvantage relative to point-in-time measures.

Model 5 includes the time-invariant control variables along with duration weighted exposure to neighborhood disadvantage. The Hispanic-White disparity in violence remains zero, whereas the magnitude of the coefficients for Multiracial and Black youth have been reduced substantially (compared to Model 1), although they remain significant. Control variables have significant effects in theoretically expected directions that mirror the findings in Table  4 .

KHB Decomposition

Table 6 presents the results from the KHB decomposition analyses. The KHB method decomposes the total effect of a variable into direct and indirect effects (Karlson et al. 2012 ), including both discrete and continuous variables, providing a test of mediation. The KHB method was not designed specifically to decompose effects for GLM models and so estimates should be interpreted with some caution. The decomposition compares the coefficients of the ethnoracial variables between models that alternately include the duration weighted measure of disadvantage (Model 5 of Tables 4 and 5 are used as input). The difference between the coefficient of the ethnoracial variables in the two models reveals the portion of the total effect that is mediated by duration-weighted exposure to neighborhood disadvantage.

With respect to caregiver reports of aggression, findings indicate that about 70% of the total Multiracial-White difference, 87% of the total Black-White difference, and about 217% Footnote 2 of the Hispanic-White difference in aggression is explained by duration-weighted exposure to neighborhood disadvantage. With respect to youth self-reports of violence, about 45% of the total Multiracial-White difference, 52% of the Black-White difference, and about 80% of the Hispanic-White difference is attributable to long-term exposure to neighborhood disadvantage. The results highlight the consequences of prolonged exposure to neighborhood disadvantage for aggression and violence outcomes, especially during childhood.

Discussion and Conclusion

This study addresses a series of issues that are critical for the neighborhood effect literature as it pertains to studies of aggression and self-reported violence. First, and perhaps most importantly, the results support a growing body of literature documenting the importance of duration of exposure to neighborhood disadvantage (Kravitz-Wirtz 2016a , b ; Wodtke 2013 ; Wodtke et al. 2011 ). Most studies do not differentiate between individuals or families that are intermittently exposed to socioeconomically disadvantaged neighborhoods from those that experience a longer duration of exposure, and some studies have suggested that there is no need to make this distinction (Kunz et al. 2003 ). Our findings support the hypothesis that duration weighted measurement of disadvantage exerts a larger effect on adolescent aggressive and violent behavior than the cross-sectional (i.e., point in time) estimate. When both measures are included in the same model, only the duration weighted measure retains significance.

The distinction intersects directly with multilevel racial invariance research, particularly studies that address ethnoracial differences in aggression and violence (e.g., McNulty and Bellair, 2003b ). Shaw and McKay ( 1942 ) argued that the neighborhood contexts experienced by poor Blacks, in particular, are qualitatively distinct from those of predominantly White neighborhoods. This logic is the basis of the racial invariance thesis, wherein ethnoracial differences in delinquency, particularly violence, are the result of group-specific exposure to neighborhood structures, particularly concentrated disadvantage (Sampson and Wilson 1995 ). We find, as have others, that Black and Hispanic families are more likely to be exposed to disadvantage and experience greater socioeconomic inequality relative to White families. Findings reveal that prolonged exposure to neighborhood disadvantage explains the Black-White disparity in aggression and that Hispanics are at a significantly lower risk of aggressive behavior relative to Whites (Table  4 ). Regarding youth self-reported violence, duration weighted exposure explains the Hispanic-White disparity in violence, and substantially mediates Multiracial and Black effects (Tables 5 and 6 ). The analysis indicates that duration weighted exposure to neighborhood disadvantage explains a larger share of the association with aggression and violence than does the point in time measure. We conclude that point in time estimation is not a proxy for duration weighted exposure despite the fact that those measures are typically correlated.

We suggest that analyses of neighborhood effects should be wary of this distinction in future research. It will also be important to replicate these findings and to go beyond with analysis of delinquency scales that tap into serious misbehavior that is likely to draw official attention from schools and the criminal justice system, including more serious forms of violence for which ethnoracial disparities are especially pronounced. In addition, multilevel models addressing neighborhood effects on individual-level disparities in violence are needed to revisit the racial invariance thesis using duration weighted exposure measures. Our results provide additional evidence that longer term exposure to concentrated neighborhood disadvantage is quite detrimental to families and children, and that it is directly associated with aggression and violence.

Beyond the issue of the importance of duration weighted disadvantage, the results for the primary caregiver reports of aggression indicate that conventional regression models often overcontrol for individual-level socioeconomic characteristics (e.g., family SES), leading researchers to underestimate neighborhood effects (Elwert and Winship 2014 ; Greenland 2003 ). As Wodtke et al. ( 2011 ) advocate, we use marginal structural modeling (MSM) with inverse probability of treatment weights (IPTW) to correct for the tendency to underestimate neighborhood effects.

We recognize the difficulty of addressing these issues in prior research. Cross-sectional datasets lack the detailed migration information needed to correctly characterize the duration of exposure to neighborhood disadvantage, but longitudinal data sets offer the opportunity to document these exposures. The issue can be rectified by geocoding previous addresses retrospectively. Yet, even with that information, it is unlikely that most longitudinal data sets contain the residential addresses of previous generations and thus cannot fully address the generational issues raised by Sharkey and Elwert ( 2011 ). The results presented here do not include generational data, but even without it, we are still able to pick up and document strong duration weighted effects on youth aggression and violent behavior.

The analysis has limitations, in particular the gaps between waves in the FFCWS prevent us from forming a more accurate estimate of long-term exposure to neighborhood disadvantage. For example, wave 1 and wave 2 are conducted at birth and at age 1, but subsequent follow-ups do not occur until age 3 and then again at age 5. The final wave we utilize for the disadvantage measures takes place when children are 9 years old. Although respondents are asked whether they changed residences between the follow-ups, there is no available residential geocode from which tract-level census data could be merged for the intervening years. This could be improved in future research with data sets that have annual geocoded residential information. Beyond the issue of measuring youth’s exposure to disadvantage is the issue of measuring parent’s residential patterns. This latter point addresses intergenerational patterns of exposure, which are likely to vary significantly between and importantly within ethnoracial groups.

Overall, we think that the findings open up new possibilities to investigate neighborhood effects in criminology. There are several subareas in which neighborhood effects are prominent, including the delinquency, gang, recidivism, and conflict literatures, among others. Neighborhoods clearly matter, but so does measurement. In closing, we second Sharkey’s ( 2013 ; 2014 ) insight that researcher’s should refocus attention away from asking whether neighborhoods matter for families and youth outcomes, and towards investigation of how they matter, especially duration of exposure.

Factor loadings for Neighborhood Disadvantage: proportion no high school degree .399; proportion in poverty = .450; proportion unemployed = .384; proportion of properties that are vacant .123; proportion of female-headed households .432; proportion of residents who are non-white .368; median household income .392.

Duration weighted exposure to neighborhood disadvantage explains more than 100% of the total Hispanic-White difference since lower levels of aggression among Hispanic youth relative to White youth is suppressed via exclusion of disadvantage from models.

Study to Determine the Clinical Significance of Intravascular OCT-NIRAF

• Study Details
• Tabular View
• No Results Posted

Patients undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF at baseline and with CCTA 12 months apart to demonstrate that:

• NIRAF coronary artery signal level (patient, artery, lesion basis) is correlated with the severity of coronary artery disease.
• NIRAF coronary artery signal level is a predictor of plaque progression on a per patient, per artery, or per lesion basis.

This study will provide preliminary data on the clinical value of intracoronary OCT-NIRAF imaging in patients undergoing invasive coronary angiography in the cardiac catheterization laboratory. This is a single site, prospective feasibility study where 40 study subjects undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will undergo intravascular imaging, including standard-of-care IVUS and then OCT-NIRAF pullback imaging conducted during an iodinated contrast flush. Patients will be consented prior to catheterization. Patient characteristics such as age, sex, BMI, and current medication regimen will be recorded. Standard of care blood chemistry will be reviewed and lab values from the subject's electronic medical records will be input into the study's Case Report Form when available. A complete medical history and data regarding prescribed cardiac medications also be transcribed from the EMR into the CRF.

Coronary Angiography will be performed. For patients for whom coronary angiography provides a clinical indication for intravascular imaging or PCI without any exclusion criteria, 40 study subjects will undergo intravascular imaging, including standard-of-care IVUS and then research study OCT-NIRAF pullback imaging, conducted during an iodinated contrast flush.

Intravascular imaging of the PCI target artery will be done prior to PCI unless the interventional cardiologist determines that intervention is required to deliver the imaging catheters. The other major coronary arteries may also be imaged by IVUS and OCT-NIRAF based on clinical assessment of the appropriateness of imaging by the interventional cardiologist.

In addition, patients will obtain a baseline coronary CTA at MGH, using standard clinical protocols in the MGH Department of Radiology.

Follow up imaging: After 12 months (+/- 28 days), patients will undergo a follow-up study coronary CTA, to assess for plaque progression compared to the baseline coronary CTA.

Follow up by phone: Patients will undergo standard-of-care cardiology follow-up and telephone clinical follow-up by study staff at 1 month (+/- 7 days), 6 months (+/- 28 days), and 1 year (+/- 28 days). After completion of the CCTA and final telephone 12-month follow-up, patients will be released from the study.

Inclusion Criteria:

• Patients with stable CAD or acute coronary syndromes undergoing invasive coronary angiography in the MGH cardiac catheterization laboratory
• Patient is eligible for PCI
• Patients must be over the age of 18
• Patient must be able to give informed consent
• Women with childbearing potential must have a negative pregnancy test within seven days prior to the procedure

Exclusion Criteria:

CLINICAL EXCLUSION CRITERIA:

Novel study quantifies immense economic costs of mental illness in the u.s..

(Illustration by Michael S. Helfenbein)

Mental illness costs the U.S. economy $282 billion annually, which is equivalent to the average economic recession, according to a new study co-authored by Yale economist Aleh Tsyvinski .

The first-of-its-kind study integrates psychiatric scholarship with economic modeling to better understand the macroeconomic effects of mental illness in the United States.

The study was prepared as a working paper of the National Bureau of Research, a private nonprofit U.S. organization that includes researchers from leading U.S. universities, economics professional organizations, and the business and labor communities.

The $282 billion estimate — which amounts to about 1.7% of the country’s aggregate consumption — is about 30% larger than previous approximations of mental illness’s overall cost in epidemiological studies.

While those earlier studies focused on income loss relating to mental illness and the costs of mental health treatment, the new study also accounted for a host of additional adverse economic outcomes associated with mental illness, including the fact that people with mental illness consume less, invest less in a house, stocks and other risky assets, and may choose less-demanding jobs, Tsyvinski said.

“ In this paper, we develop the first integrated model of macroeconomics and mental health building on classic and modern psychiatric theories,” said Tsyvinski, the Arthur M. Okun Professor of Economics in Yale’s Faculty of Arts and Sciences and professor of global affairs in the Yale Jackson School of Global Affairs. “We show that mental illness alters people’s consumption, savings, portfolio choices, as well as the country’s labor supply, generating enormous annual costs to our economy.”

Nationwide, more than 20% of adults live with mental illness and about 5.5% experience serious mental illness, according to the U.S. Substance Abuse and Mental Health Services Administration. 

For the study, Tsyvinski and co-authors Boaz Abramson, of Columbia Business School, and Job Boerma, of the University of Wisconsin-Madison, analyzed the potential effects of policies aimed at improving treatment of mental illness. They found that expanding the availability of mental health services — by eliminating the shortage of mental health professionals, among other means — would reduce mental illness by 3.1% and bring societal benefits equivalent to 1.1% of aggregate consumption.

Providing mental health services to everyone between the ages of 16 and 25 experiencing mental illness would reap societal benefits equal to 1.7% of aggregate consumption, according to the study.

At the same time, their analysis found that lowering the out-of-pocket cost of mental health services does not substantially reduce the share of people with mental illness and provides only minor economic gains. The researchers suggest that the monetary costs of mental health services are relatively low, meaning that reducing costs does not lead to greater uptake in treatment nor does it significantly reduce instances of mental illness.

The researchers model mental illness as a state of negative thinking and a state of rumination — the uncontrollable and repetitive preoccupation with negative thoughts — that is reinforced through behavior. In that model, they say, individuals experiencing mental illness are pessimistic about their future productivity, risky investments, and the evolution of their mental health. They also lose time while ruminating. As a result, they work, consume, and invest less while also foregoing treatment, which reinforces their mental illness. 

The study typifies the cross-disciplinary approach to economic questions of major policy and societal importance that is a hallmark of the scholarship produced by Yale’s Department of Economics over more than 50 years — including Yale economist William Nordhaus’s pioneering work combining economic modeling with climate science to predict the costs of climate change.

“ Economics and psychiatry have developed over 50 years, but they don’t speak to each other very much,” he said. “Here, we’ve put them in conversation in a way that enlightens both and provides us a stronger sense of the societal costs of mental illness as well as what can be gained through policies that seek to expand and improve mental health care.”
