Quick answer
A dissertation introduction (Chapter 1) normally includes background, problem statement, purpose, research questions, theoretical framework, nature of the study, definitions, assumptions and limitations, and significance. Write it last or revise it last so it matches your final methods and findings.

Key takeaways
- The introduction chapter sets the foundation for your entire dissertation
- Your problem statement should identify a specific, evidence-supported gap
- Purpose statements should clearly state the study type, focus, and population
- Research questions must be answerable through your chosen methodology
- The theoretical framework provides the intellectual lens for your study
- Address significance at multiple levels: scholarly, practical, and social
The Role of Your Introduction Chapter
Your dissertation's introduction chapter is the gateway to your entire research project. It sets the stage, establishes context, and convinces readers that your study addresses a significant problem worth investigating. A strong introduction creates momentum that carries through the rest of your dissertation.
The introduction typically runs 15-30 pages for a doctoral dissertation and includes several critical components: background of the problem, statement of the problem, purpose of the study, research questions or hypotheses, significance of the study, theoretical or conceptual framework, definition of key terms, assumptions and limitations, and a chapter overview.
Crafting Your Problem Statement and Purpose
The problem statement is the heart of your introduction. It identifies a specific gap in knowledge, practice, or theory that your research addresses. A strong problem statement answers: What is the problem? Who does it affect? What evidence demonstrates this is a real problem? What happens if it's not addressed?
Your purpose statement then explains what your study will do about this problem. It should be concise, typically one or two sentences: 'The purpose of this [quantitative/qualitative/mixed methods] study was to [examine/explore/investigate] [specific focus] among [population] at [location].'
Research questions flow directly from the purpose statement. Each question should be answerable through your chosen methodology, specific enough to guide your study, and significant enough to warrant investigation. Most dissertations have 2-5 research questions.
Theoretical Framework and Significance
Your theoretical or conceptual framework is the lens through which you examine your research problem. It provides the intellectual structure for your study, guiding your research questions, methodology, and interpretation of findings.
A theoretical framework draws on established theories to explain and predict the phenomena you're studying. A conceptual framework is a researcher-developed model that synthesizes relevant concepts, theories, and empirical findings into a visual or narrative representation of how variables relate.
The significance section argues for why your study matters. Address significance on multiple levels: contribution to scholarly knowledge (filling the gap identified in your problem statement), practical implications (how practitioners, policymakers, or organizations benefit), and potential for social change (broader impact on communities or society).
