What is a Research Gap: Types, Examples & How to Identify

What a research gap is, its types, examples, and how to identify one to make your study unique and impactful.

What is a Research Gap?

Research gap is a question or a problem that has not been answered by any of the existing studies or research within your field. Sometimes, a research gap exists when there is a concept or new idea that hasn’t been studied at all. Sometimes you’ll find a research gap if all the existing research is outdated and in need of new/updated research. Perhaps a specific population has not been well studied (perhaps there are plenty of studies on teenagers and video games, but not enough studies on toddlers and video games, for example). These are just a few examples, but any research gap you find is an area where more studies and more research need to be conducted. 

What is a Research Gap Example?

Research gap signifies an unexplored terrain within existing knowledge, spotlighting an area lacking comprehensive investigation. Imagine, in medical research, a void in understanding the long-term effects of a newly developed treatment. This gap identification demands inquiry to bridge the chasm between current understanding and untapped insights. It’s akin to a puzzle with a missing piece, urging scholars to unravel hidden complexities. Such gaps drive scholarly exploration, fostering innovation and a deeper grasp of intricate subjects. Identifying and addressing these literature gaps in research pave the way for scientific advancement, enhancing our comprehension of the world around us.

How to Identify Research Gap?

Given the vast amount of research available, identifying research gaps may feel overwhelming. I can’t read every paper on public health, and neither can you. So, how do we find a research gap?

Different disciplines use various techniques, but we can simplify the process into a few key steps:

  • Define your main research question or issue.
  • Identify key terms related to your topic.
  • Review existing literature using these key terms.
  • Examine the references cited in key publications.
  • Pinpoint issues the literature hasn’t addressed regarding your core question.

Last step is often the hardest – spotting what an article doesn’t say. I keep notes on biases or inconsistencies and track authors’ suggestions for future research, as these often highlight existing gaps.

Different Types of Research Gaps

Identifying research gaps is an essential step in conducting research, as it helps researchers to refine their research questions and to focus their research efforts on areas where there is a need for more knowledge or understanding.

1. Knowledge gaps

These are gaps in knowledge or understanding of a subject, where more research is needed to fill the gaps. For example, there may be a lack of understanding of the mechanisms behind a particular disease or how a specific technology works.

2. Conceptual gaps

These are gaps in the conceptual framework or theoretical understanding of a subject. For example, there may be a need for more research to understand the relationship between two concepts or to refine a theoretical framework.

3. Methodological gaps

These are gaps in the methods used to study a particular subject. For example, there may be a need for more research to develop new research methods or to refine existing methods to address specific research questions.

4. Data gaps

These are gaps in the data available on a particular subject. For example, there may be a need for more research to collect data on a specific population or to develop new measures to collect data on a particular construct.

5. Practical gaps

These are gaps in the application of research findings to practical situations. For example, there may be a need for more research to understand how to implement evidence-based practices in real-world settings or to identify barriers to implementing such practices.

Examples of Research Gap

Limited understanding of the underlying mechanisms of a disease:

Despite significant research on a particular disease, there may be a lack of understanding of the underlying mechanisms of the disease. For example, although much research has been done on Alzheimer’s disease, the exact mechanisms that lead to the disease are not yet fully understood.

Inconsistencies in the findings of previous research:

When previous research on a particular topic has inconsistent findings, there may be a need for further research to clarify or resolve these inconsistencies. For example, previous research on the effectiveness of a particular treatment for a medical condition may have produced inconsistent findings, indicating a need for further research to determine the true effectiveness of the treatment.

Limited Research on Emerging Technologies:

As new technologies emerge, there may be limited research on their applications, benefits, and potential drawbacks. For example, with the increasing use of artificial intelligence in various industries, there is a need for further research on the ethical, legal, and social implications of AI.

2. Letters of Recommendation: References from employers, mentors, or supervisors can vouch for your activities during the study gap.

3. Resume/CV: Highlight your achievements, work experiences, or projects undertaken during the study gap period.

4. Medical Certificate and Doctor’s Report: If a medical condition was a factor in your study gap, submitting a medical certificate and a report from your doctor can substantiate your claim.

5. Employment or Internship Verification: If you were employed or undertook internships, include experience certificates, a letter from your employer detailing your role during the study break, or even salary records to confirm your involvement.

6. Proof of Volunteer or Social Work: For instances where you were engaged in volunteer or social work, having participation documentation can underline your commitment.

7. Certificates from Courses: If you completed any certificate programs or took part-time classes during your gap, presenting the corresponding diplomas or certificates can validate your productive use of that time.
