How to Write the Purpose of the Study for a Psychology Dissertation

How to write the Purpose of the Study for a psychology dissertation. The Purpose of the Study section in a psychology dissertation explains the main goal of your research. It tells the reader what psychological issue you are studying, who is being studied, and what your research aims to explore, examine, or understand.

A strong purpose statement in Chapter 1 helps connect your problem statement, research questions, and methodology into a focused and organized study. In psychology, it should clearly identify the psychological phenomenon being investigated and explain the overall objective of the research.

What Is the Purpose of the Study in a Psychology Dissertation?

The Purpose of the Study is a brief section that:

• Explains the main goal of the research

• Identifies the psychological topic being studied

• Specifies the population or setting

• Indicates the research methodology when appropriate

It answers the question: "What is this psychology study trying to accomplish?”

Why Is the Purpose Statement Important?

The purpose statement is important because it:

• Provides direction for the dissertation

• Clarifies the goals of the research

• Connects the problem statement to the methodology

• Helps readers understand the study’s focus

• Guides the development of research questions and hypotheses

Without a clear purpose statement, the dissertation may seem unfocused or incomplete.

Where Does the Purpose of the Study Go?

In most psychology dissertations, the Purpose of the Study appears in Chapter 1 after:

1. Background of the Problem

2. Problem Statement

It usually comes before:

• Research questions

• Hypotheses

• Significance of the study

Step 1: Identify the Research Method

Most psychology purpose statements begin by identifying the research design.

Examples:

• “The purpose of this qualitative study…”

• “The purpose of this quantitative study…”

• “The purpose of this mixed methods study…”

This immediately tells the reader how the research will be conducted.

Step 2: State the Psychological Topic

Clearly identify the psychological issue, behavior, or mental process being studied.

Examples:

• Anxiety

• Depression

• Stress

• Self-esteem

• Social media use

• Coping behaviors

• Cognitive performance

Be specific and focused.

Step 3: Identify the Population Being Studied

Specify who the participants are.

Examples:

• Undergraduate students

• Adolescents

• Adults with anxiety disorders

• Healthcare workers

• Postgraduate psychology students

This helps define the scope of your study.

Step 4: Explain the Goal of the Research

Use action verbs to explain what your study aims to do.

Common verbs include:

• Explore

• Examine

• Investigate

• Compare

• Determine

• Evaluate

• Understand

Example:

“The purpose of this study is to examine the relationship between academic stress and sleep quality among university students.”

Step 5: Keep the Purpose Statement Clear and Concise

A purpose statement is usually one short paragraph. Avoid excessive detail or lengthy explanations.

A strong psychology purpose statement should:

• Be specific

• Be easy to understand

• Align with the problem statement

• Match the research methodology

A focused and specific statement strengthens the dissertation.

Purpose Statement vs Problem Statement in Psychology

These sections are related but serve different purposes.

Problem Statement	Purpose Statement
Explains the psychological issue or gap	Explains the goal of the study
Identifies what is missing in research	Describes what the study will do
Focuses on the problem	Focuses on the research objective

Both sections work together to create a clear research direction.
