What is a Literature Review?

A literature review section of the research paper analyzes and evaluates the existing knowledge and theories on a specific topic. The sources include research papers, books, journals, scholarly articles, and legit reports that a researcher analyzes to conduct his research.

Moreover, a literature review focuses on the previous studies and their limitations. The writer also discusses the research question and its relevance to the study to support his claim. 

Writing a literature review is of great importance. Whether drafting it for your research paper, thesis, or dissertation, a literature review is essential. The following are the reasons why a literature review should be written:

  • Presents the writer’s understanding, and knowledge of the topic
  • A literature review develops a theoretical framework for your research. 
  • It also paves the way for the research methodologies for the writer. 
  • Studies the gaps and limitations in the previous studies to contribute to the field
  • Resolve conflicts among the previous studies. 

Why Do We Write a Literature Review? 

A literature review serves several important purposes in research. 

It helps researchers to:

  • Identify gaps in the existing research
  • Establish the need for their own research
  • Provide context for the research
  • Inform the research design
  • Generate research hypotheses

By reviewing the existing literature on a topic, researchers can determine what has already been studied and what questions remain unanswered. 

This allows them to design research that addresses important gaps in the literature and makes a meaningful contribution to the field.

How to Write a Literature Review in Research? 

Like every other formal piece of writing, a literature review requires a proper process and structure to be effective.

If you are drafting this document for the first time, follow these steps on how to write a literature review:

1. Choose Relevant Literature Sources

For knowing how to star a literature review, it is essential to have a clear and definite topic. Once you have a focused research question, finding a literary source will be more comfortable.It is important to keep in mind that the sources you choose should be relevant to the topic.

Whereas, if writing a separate assignment, the review should have a central focused question. This question is answered in the literature review without collecting the original data by reviewing existing publications.

Look for credible sources such as review articles, journals, and books that perfectly complement your topic. Moreover, gather related keywords and fundamental concepts for your research subject. 

2. Analyze and Evaluate the Sources

Reading every source thoroughly is impossible. Instead, professionals suggest analyzing and evaluating sources that relate best to your topic. To analyze the chosen sources, determine the following factors and elements.

  • The major problem or question discussed.
  • The key concepts
  • How are those key points defined?
  • Key theories and methods
  • Did the research use an innovative approach or a defined framework?
  • Results of the study
  • How does the work relate to other literature in the field?
  • The contribution of work in the understanding of your topic.
  • The strengths and weaknesses of the research.

To ensure which source is adding to your research, search how many times it has been used in other works. If it is popularly used, it means it is influential in the field. 

Moreover, keep in mind that you only consider the latest literature for science-related research. At the same time, old historical perspectives can also be studied for humanities. 

3. Take Frequent Notes

While reviewing and evaluating sources, take frequent notes. These notes will later be incorporated into your review. 

To avoid plagiarism and cheating, keep track of all the sources along with the citations. These notes will be helpful in creating the annotated bibliography as well.

Keep in mind the formatting style required to structure your paper and follow it in your literature review.

4. Identify the Connections Between the Sources

Before you organize the data for your literature review, it is important to determine the relationship between the sources. Identify the following elements to study the connection:

  • Identify the trends in theories, methods, and results and how certain approaches changed over time.
  • Determine the themes of the literature.
  • The conflicts and contradictions between the sources.
  • Do theories or studies influence change the direction of the field?
  • What are the gaps, limitations, and weaknesses of the literature?

5. Develop a Literature Review Outline

The information for your literature review can organize in multiple ways. Choose a strategy to outline your document according to the length and the other requirements. 

  • Chronological - This is the simplest structure through which the writer develops the topic over time. Instead of summarizing the sources in order, analyze the patterns and key debates that shaped the field.
  • Methodological - If the gathered sources use different research methods and are from different fields, compare the results. Include the following analysis:
    • Findings obtained from the qualitative and quantitative research
    • How is the topic analyzed? Through a theoretical or empirical approach?
    • Arrange the literature in different sections such as historical, cultural, and social.
  • Thematic - If there are multiple themes in the sources, you can organize your literature review into subsections.
  • Theoretical - The literature review also discusses various theories, models, key concepts, and definitions. It can be used to create a framework for your research studies.

6. Draft the Literature Review

A literature review is a piece of formal writing that needs to be structured in order to be effective. This literature review structure is divided into three major sections:

  1. Introduction
  2. Body Paragraphs
  3. Conclusion

Once you have decided on the outline, start writing your literature review. The first section to draft is the introduction. Present the following information in this part:

  • Purpose of the literature review
  • Literature gaps and limitations
  • Background information of the topic
  • Scope of the literature and your research objectives
  • Hypothesized results

After briefly presenting the introduction section, provide a detailed body section. The body is the main part of your review, so keep it informative and direct. Add the following elements in this section:

  • Overview of the main points of the sources
  • Interpret sources and their findings
  • Present strengths and weaknesses 

The above information in the literature review should lead the audience to a conclusion. To conclude your literature review, summarize the key findings and present the importance of the results obtained.

After completing the conclusion paragraphs, proofread and make edits if required. Make sure that your document is free from all errors and mistakes.

Literature Review Format 

When writing a literature review, it's important to follow a structured format to ensure that your review is comprehensive, focused, and organized. 

A typical literature review format includes the following sections:

Introduction

  • The introduction provides an overview of the topic, the purpose of the review, and the scope of the review.
  •  It should also include a  clear research question or objective that guides the review.

Methodology

  • The methodology section describes the search strategy and criteria used to identify the relevant studies. 
  • This section should also describe the inclusion and exclusion criteria used to select studies for the review.

Results

  • The results section summarizes the findings of the selected studies. This section can be organized by themes, research questions, or types of studies. 
  • It should provide a synthesis of the main findings of the studies and identify areas of agreement and disagreement among the studies.

Discussion

  • The discussion section provides an interpretation of the results and their implications for the research question or objective. 
  • This section should also identify the limitations of the review and suggest areas for future research.

Conclusion

  • The conclusion section summarizes the main findings of the review and their implications for the research question or objective. 
  • It should also highlight the contributions of the review to the existing literature and suggest future research directions.

Types of Literature Review 

The literature review has two main types.

1. Research literature review

This contains research that has been done before. It looks at experiments that have been published and reports on what they found. It gives an overview of; 

  • Who are the key writers?
  • The methods and methodologies that have proved useful
  • The prevailing theories and hypotheses
  • What has been said?
  • The questions being asked

Here is an example of a research literature review:

Title: The effects of mindfulness meditation on stress and anxiety levels in college students: a systematic review of the literature

Introduction:

Mindfulness meditation has gained popularity as a tool for reducing stress and anxiety in various populations, including college students. In this systematic review, we aim to synthesize the existing literature on the effects of mindfulness meditation on stress and anxiety levels in college students.

Methods:

We searched three electronic databases (PubMed, PsycINFO, and Cochrane Library) for studies that investigated the effects of mindfulness meditation on stress and anxiety in college students. Studies that met the inclusion criteria were reviewed and synthesized using a narrative approach.

Results:

We identified 10 studies that met our inclusion criteria. The studies varied in terms of sample size, intervention duration, and type of mindfulness meditation used. Overall, the studies provided moderate to strong evidence that mindfulness meditation is effective in reducing stress and anxiety levels in college students. However, some studies reported mixed results, suggesting that mindfulness meditation may not be effective for all college students.

Conclusion:

The findings of this systematic review support the use of mindfulness meditation as a tool for reducing stress and anxiety levels in college students. However, further research is needed to determine the optimal type and duration of mindfulness meditation interventions for this population. Additionally, studies that examine the long-term effects of mindfulness meditation on stress and anxiety levels in college students are warranted.

2. Systematic or evidence-based literature review 

These reviews are used to find the best way to help people. The reviews look at all the different ways to help people and then decide on the best way.

It involves:

  • A standardized and transparent process
  • Critical appraisal of the selected studies for their quality and relevance
  • Synthesizing the findings across studies using appropriate statistical methods 

Here's an example of a systematic or evidence-based literature review:

Title: The effectiveness of cognitive-behavioral therapy for depression in older adults: a systematic review and meta-analysis

Introduction:

Depression is a significant mental health problem among older adults, and cognitive-behavioral therapy (CBT) is a commonly used treatment for this population. In this systematic review and meta-analysis, we aim to synthesize the existing evidence on the effectiveness of CBT for depression in older adults.

Methods:

We conducted a comprehensive search of four electronic databases (PubMed, PsycINFO, Cochrane Library, and Web of Science) for studies that investigated the effectiveness of CBT for depression in older adults. Studies that met our inclusion criteria were evaluated for quality and synthesized using a random-effects meta-analysis.

Results:

We identified 16 studies that met our inclusion criteria and provided data on the effectiveness of CBT for depression in older adults. The studies varied in terms of sample size, intervention duration, and type of CBT used. The meta-analysis revealed a significant overall effect size for CBT on depression outcomes in older adults, with a standardized mean difference of -0.50 (95% confidence interval: -0.68 to -0.32, p < 0.001). The effect size was robust to sensitivity analyses and publication bias.

Conclusion:

The findings of this systematic review and meta-analysis suggest that CBT is an effective treatment for depression in older adults. The effect size is comparable to that found in previous meta-analyses of CBT for depression in adults of all ages. However, further research is needed to determine the optimal type and duration of CBT interventions for this population, as well as the mechanisms underlying the effectiveness of CBT for depression in older adults.

Benefits of Literature Reviews
