Key takeaways
- Move from the broad topic to your specific research problem, aims and questions.
- Every section of the introduction should point to the research gap you fill.
- Write a first draft early, then revise the introduction last.
- Close Chapter 1 with a brief outline of the remaining chapters.
What Is a Dissertation Introduction Chapter?
The dissertation introduction chapter, often called Chapter 1, sets up your entire research project. It introduces the topic, explains the problem, states your aims and questions, and gives the reader a map of what follows.
- Its purpose: a dissertation introduction persuades the reader that your topic matters and that your study is needed.
- Its scope: it previews the study without reporting results or reviewing every source.
- Its length: a common guideline is about 10% of your total word count, though your program may set its own limits.
- Its tone: confident and academic, written for an informed reader who is not yet an expert in your topic.
What the introduction must do for the reader
Examiners read the dissertation introduction to decide what kind of study they are about to assess. Every researcher needs this chapter to answer four questions quickly.
- What it is about: name the topic and the context in the first paragraphs.
- Why it matters: show the problem and the gap in current knowledge.
- What you will do: state the aim, objectives and research questions.
- How it is organized: give a short outline of the chapters.
Thesis introduction vs research paper introduction
A thesis introduction is longer and more detailed than the introduction to a journal article or research paper. The logic is the same, but each part gets its own subheadings.
- Research paper: background, gap and aim in a few paragraphs, with no chapter outline.
- Master’s or PhD thesis or dissertation: a full chapter with separate sections for background, problem statement, purpose, questions, significance and scope.
- Program differences: some universities use the terms dissertation or thesis differently, so follow your graduate school’s template.
How a PhD dissertation introduction differs
A PhD dissertation introduction does the same job as a master’s intro, but examiners expect more depth. The thesis introduction chapter must show that your work makes an original contribution.
- A stronger claim to originality: a doctoral dissertation introduction states clearly what new knowledge the study adds, not only what gap it addresses.
- A fuller theoretical position: PhD introductions usually preview the theoretical framework and the main argument of the whole thesis.
- More context on methods: a brief overview of the research design helps readers follow a long, complex project.
- A longer outline: with more chapters, the outline often describes each one in two or three sentences.
Dissertation Introduction Structure and Format
Before you write the introduction, it helps to see where Chapter 1 sits in the whole dissertation. The flowchart below shows the standard five-chapter structure used by most empirical theses.
- 1. IntroductionTopic, problem, aims
- 2. Literature reviewWhat is known
- 3. MethodologyHow you studied it
- 4. ResultsWhat you found
- 5. DiscussionWhat it means
The sections of a dissertation introduction chapter
Most programs expect a dissertation introduction to include the sections below, in roughly this order. Use them as subheadings unless your guideline says otherwise; our guide to dissertation chapters and structure covers the full document.
| Section | What it does | Typical length |
|---|---|---|
| Background of the study | Context and evidence for the topic | 2–4 paragraphs |
| Problem statement | The specific problem and research gap | 1–3 paragraphs |
| Purpose, aim and objectives | What the study sets out to do | 1–2 paragraphs |
| Research questions or hypotheses | The exact questions you will answer | 2–4 questions |
| Theoretical framework (brief) | The theory that guides the study | 1–2 paragraphs |
| Significance of the study | Who benefits and how | 1–2 paragraphs |
| Scope, delimitations and definitions | The boundaries and key terms | 1–2 paragraphs plus a list |
| Outline of the dissertation | A map of the remaining chapters | 1 paragraph |
The narrative logic of the introduction
The sections of a dissertation introduction are not a checklist to fill in; they form one narrative argument. Each section should lead naturally into the next.
- Broad to narrow: start with the wide context, then narrow to your specific gap, like an inverted triangle.
- Problem drives everything: the aim answers the problem, and the research questions break the aim into parts.
- Consistent terms: use the same key words for your variables and population in every section.
How to Write a Dissertation Introduction: A 7-Step Guide
These 7 steps give you practical guidance on how to write a dissertation introduction from your first notes to a polished chapter. Most students draft it early and finish it last.
- Start writing a rough draft early. Draft Chapter 1 when you write your proposal, so your aims and questions are clear before data collection. Treat this draft as a working document you will rewrite.
- Introduce the topic and context. Open with a sentence that shows why the topic matters now, supported by recent evidence. Avoid sweeping claims such as “since the beginning of time”.
- Write the background of the study. Summarize what is already known and what has changed, citing key sources from your literature review.
- State the problem and the gap. Explain the specific problem and what current research has not yet answered, then justify why your study is needed.
- Set out your aim, objectives and research questions. Write one overarching aim, a few measurable objectives and focused research questions that follow from the gap.
- Explain significance, scope and key terms. Show who benefits from the study, set its boundaries and define the main concepts.
- Finish with a chapter outline, then revise. Write a brief paragraph that previews each chapter, and revise the whole introduction once your results and discussion are complete.
When to write the introduction
Timing matters as much as content. The best approach is to write the dissertation introduction twice: once early as a plan, and once at the end as a polished chapter.
- Proposal stage: a short draft fixes your topic, problem, aims and research questions.
- During data collection: keep notes on any change to scope, sample or questions, so Chapter 1 stays accurate.
- After the discussion and conclusion: rewrite the dissertation introduction so it matches what you actually found and argued.
What to Include in a Thesis or Dissertation Introduction: Weak vs Strong Examples
Each dissertation introduction example below uses the same research project, a study of remote work flexibility and employee retention in small technology firms. Seeing one study through every section shows how the parts connect.
Opening sentence and background
The background gives context and evidence. For a deeper guide, see how to write the background of the study.
Opening and background
Weak
“Work has always been important to people, and the world of work keeps changing.”
Generic: it could open any dissertation and says nothing about the topic.
Strong
“Since 2020, many small technology firms have adopted flexible remote work policies, yet these firms also report persistent difficulty retaining skilled staff.”
Specific, current and sets up a tension the study will explore.
Problem statement and research gap
The problem statement narrows the background to one specific issue. Our problem statement guide explains the structure in depth.
Problem and gap
Weak
“There is not much research on remote work.”
Inaccurate and vague; it does not name the specific gap.
Strong
“Studies of remote work and retention have focused mainly on large corporations, leaving little evidence on whether flexibility helps small and midsize technology firms keep employees.”
Names what is known, what is missing and which population is affected.
Aim, objectives and research questions
The aim states what you want to achieve; objectives and questions break it into steps. See our guide to writing a research question for more detail.
Aim and research question
Weak
“The aim is to look at remote work.” “Is remote work good?”
No population, no outcome and a yes-or-no question.
Strong
Aim: “To examine how remote work flexibility influences employee retention in small and midsize technology firms.” Question: “How does the degree of remote work flexibility relate to employees’ intention to stay?”
Clear variables, population and an open, answerable question.
Significance and scope
Significance explains who benefits; scope sets the study’s boundaries. Our guides on significance of the study and scope and delimitations show each section in full.
Significance
Weak
“This study is very important and will help many people.”
Empty praise; no audience or benefit is named.
Strong
“The findings may help small firm managers design remote work policies that reduce turnover, and they extend retention research to a sector it has largely overlooked.”
Names practical and academic benefits and who receives them.
A brief outline of the chapters
The final part of the dissertation introduction tells readers what each chapter contributes.
Chapter outline
Weak
“Chapter 2 is the literature review. Chapter 3 is the methodology. Chapter 4 is the results.”
Lists titles but tells the reader nothing about content.
Strong
“Chapter 2 reviews research on flexibility and turnover; Chapter 3 explains the survey design; Chapter 4 reports the regression results; Chapter 5 discusses implications for managers and future research.”
Previews what each chapter contributes to the argument.

Full dissertation introduction example (shortened)
Background. Since 2020, many small technology firms have adopted flexible remote work policies. At the same time, these firms continue to report difficulty retaining skilled employees, and replacing staff is costly for organizations with small teams.
Problem statement. Research on flexibility and retention has focused mainly on large corporations. Whether flexibility helps smaller firms keep employees remains unclear, leaving managers with little evidence to guide policy.
Purpose and research questions. The purpose of this quantitative study is to examine how remote work flexibility relates to employee retention in small and midsize technology firms. Two research questions guide the study, focusing on intention to stay and on the role of perceived autonomy.
Significance and scope. The findings may inform remote work policies in smaller firms. The study is limited to full-time employees in U.S. firms with fewer than 500 staff.
Outline. Chapter 2 reviews the literature, Chapter 3 explains the methodology, Chapter 4 presents the results and Chapter 5 discusses the implications. A full example study on remote work flexibility and employee retention shows the complete version.
What changes in a qualitative introduction
In a qualitative study, the purpose statement uses open verbs such as “explore” or “understand”, and research questions ask “how” or “what” rather than predicting relationships. Hypotheses are usually left out.
The background and problem sections often emphasize lived experience, and the significance section may stress understanding a group whose voices are missing from existing research.

Common Mistakes and Essential Advice for Your Introduction
Most weak dissertation introduction chapters fail for the same few reasons. Use this brief checklist before you send the chapter to your supervisor.
Common mistakes to avoid
- Starting too broadly: opening sentences about “society” or “the modern world” waste the reader’s attention.
- No clear gap: if you cannot name what is missing in existing research, you cannot justify the study.
- Too much literature: the introduction previews key sources; the detailed review belongs in Chapter 2.
- Reporting results: do not reveal findings in Chapter 1.
- Mismatched parts: aims, objectives and research questions that use different terms confuse examiners.
Essential tips for a strong PhD or master’s introduction
- Write for the examiner: assume an intelligent reader who needs the argument laid out clearly.
- Use evidence early: support claims in the background with recent, credible sources from journals and official reports.
- Keep sentences focused: one main idea per sentence makes complex arguments easier to follow.
- Revise last: once the discussion and conclusion are done, check that your dissertation introduction promises exactly what the dissertation delivers.

Dissertation Introduction FAQs
How long should a dissertation introduction be?
A common guideline is that the dissertation introduction takes up about 10% of the total word count. For a 15,000-word master’s dissertation, that is roughly 1,500 words; for a PhD thesis of 80,000 words, it may be 5,000 to 8,000 words. These figures are rules of thumb, not fixed requirements.
Your university handbook or supervisor may set different limits, and some fields expect shorter introductions. Focus on covering every required section clearly rather than reaching a target word count, and cut anything that belongs in the literature review.
What should be included in a dissertation introduction?
Most dissertation introductions include the background of the study, the problem statement, the purpose or aim, objectives, research questions or hypotheses, the significance of the study, the scope and delimitations, definitions of key terms and an outline of the chapters.
Some programs also ask for a brief theoretical framework and an overview of the methodology. The exact list varies by university, so check your template first. Whatever the list, every section should connect to the same research gap, so the chapter reads as one argument rather than a set of separate parts.
Should I write the introduction first or last?
Write a first draft early and the final version last. A draft written during your proposal stage helps you clarify your aims, research questions and scope before you collect data. However, your study will change as you work, so the introduction must be revised once your results and discussion are complete.
Revising last ensures that Chapter 1 promises exactly what the dissertation delivers. Many students find that their final introduction is much shorter and sharper than their first draft, because they finally know which parts of the background matter most.
What is the difference between the introduction and the literature review?
The introduction gives a short, focused overview of the context and the gap, using only the key sources needed to justify the study. The literature review, usually Chapter 2, examines the research in depth: it compares studies, evaluates methods and builds a detailed case for your research questions.
A useful test is length and depth. If you find yourself discussing several studies in detail in Chapter 1, move that material to the literature review and leave a brief summary in the introduction, with a sentence pointing readers to the full review.
How do I start a dissertation introduction?
Start with a sentence that places your topic in a specific, current context and shows why it matters. Good openings use a recent trend, a striking piece of evidence from a credible source or a clear tension in the field. Avoid generic openings about history or society, which add words without adding meaning.
After the opening, move quickly to the background and the problem, so the reader understands within the first page what your study is about. Strong first paragraphs make examiners confident about the quality of the rest of the dissertation.
