How to Perform a Review of Related Literature for Chapter 2 of a Psychology Doctoral Dissertation

How to perform a Review of Related Literature for Chapter 2 of a psychology doctoral dissertation. The Review of Related Literature (RRL) in Chapter 2 of a psychology doctoral dissertation is a critical, structured analysis of existing psychological research. It goes beyond summarizing studies and instead evaluates, compares, and synthesizes findings to build a strong scientific foundation for your research problem.

In psychology, this process is especially important because it connects your study to established theories of behavior, cognition, emotion, and mental processes.

A strong literature review helps you justify your research questions, identify gaps in psychological knowledge, and position your study within the broader field.

What Is the Literature Review in a Psychology Dissertation?

The literature review is a scholarly examination of existing research related to your psychological topic.

It:

• Summarizes key psychological studies

• Evaluates research methods and findings

• Identifies patterns in human behavior research

• Highlights contradictions or gaps in the literature

• Connects findings to psychological theories

In simple terms, it answers: “What do we already know about this psychological phenomenon, and what still needs to be studied?”

Why Is the Literature Review Important in Psychology?

A strong Chapter 2 literature review allows you to:

• Demonstrate understanding of psychological research

• Ground your study in established theories

• Identify gaps in mental health or behavioral research

• Justify your research design and methodology

• Strengthen the validity of your study

Without a strong literature review, your dissertation lacks scientific context and credibility.

Step-by-Step: How to Perform a Literature Review in Psychology

Step 1: Clearly Define Your Psychological Research Focus

Start by identifying:

• Your psychological phenomenon (e.g., anxiety, motivation, trauma)

• Target population (e.g., students, adults, patients)

• Key variables (e.g., stress, coping, cognition)

• Research purpose

A clearly defined topic helps narrow your search and improve relevance.

Step 2: Search for Peer-Reviewed Psychological Research

Use trusted academic databases such as:

• PsycINFO

• PubMed

• Google Scholar

• JSTOR

• APA PsycNet

Focus on:

• Peer-reviewed journal articles

• Empirical studies

• Meta-analyses and systematic reviews

• Foundational psychological theories

Avoid non-academic or opinion-based sources.

Step 3: Select High-Quality Psychological Studies

Choose studies that are:

• Recent (typically within 5–10 years, unless foundational)

• Methodologically sound

• Directly related to your psychological variables

• Published in reputable journals

Also include key classic theories (e.g., Beck’s Cognitive Theory, Bandura’s Social Learning Theory).

Step 4: Organize Literature Into Psychological Themes

Instead of summarizing one study at a time, group research into themes.

Common psychology literature themes include:

• Psychological theories (e.g., CBT, attachment theory)

• Cognitive processes (e.g., memory, attention, perception)

• Emotional regulation and mental health

• Behavioral outcomes and coping strategies

• Population-specific findings (e.g., students, patients)

Thematic organization improves clarity and academic structure.

Step 5: Critically Analyze Psychological Research (Not Just Summarize)

A strong psychology literature review is critical and analytical.

Instead of writing:

“Smith (2021) found that anxiety affects performance.”

You should write:

“Smith (2021) found that anxiety negatively affects academic performance; however, the study relied on self-reported measures, which may introduce bias in psychological assessment.”

You should:

• Compare studies

• Evaluate methodologies

• Identify limitations

• Highlight inconsistencies

Step 6: Identify Gaps in Psychological Literature

A key purpose of Chapter 2 is identifying what is missing in the research.

Common gaps in psychology include:

• Understudied populations (e.g., doctoral students, minority groups)

• Limited longitudinal research

• Overreliance on self-report data

• Inconsistent findings across studies

• Lack of research in specific contexts

Example:

“Although extensive research exists on anxiety in undergraduate students, limited studies have examined anxiety among doctoral learners in online environments.”

Step 7: Connect Literature to Psychological Theory

Psychology dissertations must be grounded in theory.

Explain how:

• Theoretical frameworks explain behavior

• Prior studies support or challenge theory

• Theory guides interpretation of findings

Examples of psychological theories:

• Cognitive Behavioral Theory (CBT)

• Social Learning Theory

• Self-Determination Theory

• Attachment Theory

Example:

“Cognitive Behavioral Theory provides a framework for understanding how negative thought patterns contribute to anxiety and stress responses observed in prior studies.”

Step 8: Synthesize Psychological Research

Synthesis means combining findings across studies.

Instead of listing research, show:

• Patterns in psychological behavior

• Agreements between studies

• Contradictions in findings

• Evolution of research over time

Example:

“Overall, research suggests that cognitive distortions, environmental stressors, and emotional regulation difficulties contribute to anxiety; however, findings differ regarding the role of online learning environments.”

Step 9: End the Chapter 2 Literature Review Effectively

Conclude by:

• Summarizing key psychological findings

• Highlighting research gaps

• Transitioning to methodology (Chapter 3)

Example:

“The literature indicates a need for further research on anxiety among doctoral students in online learning environments. Chapter 3 presents the methodology used to address this gap.”

Structure of a Psychology Literature Review (Chapter 2)

A strong structure typically includes:

1. Introduction to Chapter 2

2. Theoretical framework

3. Thematic psychological literature review

4. Critical analysis and synthesis

5. Identification of research gaps

6. Summary and transition to Chapter 3

Common Mistakes in Psychology Literature Reviews

Avoid these common errors:

• Summarizing studies without analysis

• Ignoring psychological theory

• Using outdated or weak sources

• Failing to synthesize findings

• Not identifying research gaps

• Writing disconnected sections

A psychology literature review must be analytical and theory-driven.

Tips for a Strong Psychology Literature Review

• Focus on psychological constructs and theories

• Use peer-reviewed empirical studies

• Organize research into clear themes

• Critically evaluate methods and findings

• Identify gaps in psychological knowledge

• Maintain strong theoretical alignment
