What the introduction (Chapter 1) of a doctoral thesis or dissertation must do, the standard sections it contains, how to write a strong opening and problem statement, and the most common mistakes.
Why the introduction matters
The introduction is the reader’s map of your whole study. In a few pages, it must convince your committee that there is a real problem, that your study addresses a specific gap in knowledge or practice, and that your approach is sound and significant. Readers often form their judgment of a dissertation in its first chapter, so a clear introduction builds confidence in everything that follows (Booth et al., 2016).
The “funnel” approach
Strong introductions move from broad to narrow, like a funnel:
- The broad context: why this topic matters to your field and society.
- What is known: a brief summary of key research. The full review comes in Chapter 2.
- The gap: what is not yet known, understood or done.
- Your study: how your purpose and research questions address that gap.
Swales and Feak (2012) describe this pattern as “creating a research space”: establish the territory, establish a niche, then occupy the niche.
Typical sections of a dissertation introduction
Section names vary by university and by research or practice doctorate, so always follow your program’s template. Most introductions include:
| Section | What it does |
|---|---|
| Background | Explains the context and history of the topic, with current evidence |
| Problem statement | States clearly and specifically what the problem is, who it affects and what evidence shows it exists |
| Purpose of the study | One or two sentences stating what the study will do and how (design, population, setting) |
| Research questions / hypotheses (or PICOT for practice projects) | The specific questions the study will answer |
| Theoretical or conceptual framework | The theory or model that guides the study |
| Nature of the study | A brief overview of the methodology and design |
| Definitions | Key terms as used in your study |
| Assumptions, scope, delimitations and limitations | What you take as true, the boundaries you set, and known weaknesses |
| Significance | Contributions to theory, practice and positive social change |
| Summary and transition | Recaps the chapter and introduces Chapter 2 |
Writing a strong opening
Begin with the problem, not with a sweeping generalization. Compare:
| Weak opening | Strong opening |
|---|---|
| “Since the beginning of time, people have struggled with health.” | “Hospital falls injure an estimated 700,000 to 1,000,000 patients in the United States each year, yet many fall-prevention programs fail to sustain improvement beyond the first year.” |
| “Leadership is very important in organizations today.” | “Nurse manager turnover in U.S. hospitals has risen since 2020, and units with new managers report higher staff turnover and lower patient satisfaction.” |
A strong opening is specific, evidence-based and leads directly to the problem your study will address.
Writing the problem and purpose statements
- Problem statement: name the problem, provide evidence that it exists (with recent citations), and identify the gap. For example: “Although X is known, little is known about Y among Z.”
- Purpose statement: use a clear formula. “The purpose of this [qualitative/quantitative/QI] study is to [explore/examine/evaluate] [phenomenon/variables] among [population] in [setting].”
- Alignment: your problem, purpose, research questions and methodology must match. If the problem is about experiences, the purpose and questions should be qualitative.
Tip: Many doctoral writers draft the introduction first but finalize it last. Your study will evolve, so revise Chapter 1 after the other chapters are done so that it accurately introduces what you actually did.
Common mistakes to avoid
- Writing a mini literature review instead of an introduction.
- A vague problem (“there are many problems with…”) with no supporting evidence.
- Research questions that do not match the purpose or methodology.
- Overstating significance (“this study will solve…”).
- Using outdated sources. Most programs expect sources from the last 5 years for the problem statement.
- Undefined acronyms and jargon.
Conclusion
A good introduction tells the committee what the problem is, why it matters, what is missing, and how your study will fill that gap, in clear, aligned and well-supported writing. Once your introduction is in place, make sure your whole document follows the required format. Next in this series: Formatting your dissertation.
