How to Write a Problem Statement: A Complete UK Guide

Learning how to write a problem statement is an essential skill for UK university students. A problem statement defines the specific issue your research will address and explains why it matters. It is the hinge between background and aim — a clear problem statement justifies the entire study. This complete UK guide explains what a problem statement is, what it must contain, how to write one, and how it differs from a research question and a rationale.

What Is a Problem Statement?

A problem statement is a concise description of the specific problem or gap your research addresses. It tells the reader what is wrong or missing, why it matters, and sets up the need for your study.

What It Must Contain

✓  The context — the broader area.
✓  The specific problem or gap.
✓  Evidence that it matters.
✓  The consequences of leaving it unaddressed.
✓  A bridge to your aim.

How to Write One

Move from the general to the specific: start with the wider context, narrow to the exact problem, support it with evidence, and explain the impact. Keep it focused — a problem statement is usually a paragraph or two, not pages.

Problem Statement vs Research Question vs Rationale

The problem statement defines the issue; the research question asks what you will investigate about it; the rationale argues why the study is worth doing. They are linked but distinct. See our rationale guide.

Grounding It in Evidence

A convincing problem statement is evidenced, not asserted. Use the literature, data or a practice context to show the problem is real and significant — this is what makes examiners accept that your study is needed.

Common Mistakes and Tips

✓  Too broad or vague.
✓  No evidence the problem matters.
✓  Confusing it with the aim.
✓  No link to the research questions. Tip: narrow to a specific, evidenced problem and bridge to your aim.

Why the Problem Statement Is the Foundation of Your Dissertation

The problem statement is not merely a required section to complete — it is the intellectual foundation of your entire dissertation. A clear, well-evidenced and precisely framed problem statement enables everything that follows: it justifies your research questions, informs your literature review, shapes your methodology and gives your conclusions their significance.

Many UK dissertation students underestimate the importance of getting the problem statement right. A weak problem statement — one that is too vague, too broad, poorly evidenced or based on a claimed problem that the literature does not support — creates difficulties throughout the dissertation. Supervisors frequently identify a confused or underdeveloped problem statement as the root cause of structural weaknesses in later chapters.

Conversely, a strong problem statement makes the rest of the dissertation easier to write and clearer in structure. When you know precisely what problem you are addressing, why it matters, who it affects and what is currently missing in the literature, you have a clear mandate that guides every subsequent decision — what to include in the literature review, which methodology to use, and how to discuss your findings.

The Problem Statement in Different Types of UK Dissertation

The nature and position of the problem statement varies somewhat across different types of UK university dissertation, and understanding these variations helps you write one that fits your specific context.

In a social science dissertation, the problem statement typically appears in the introduction chapter and establishes a specific gap, contradiction or under-explored area in the existing research literature. It draws on empirical evidence (statistics, reported trends, policy reports) to establish the real-world significance of the problem, and on the academic literature to establish why existing research has not adequately addressed it.

In a business or management dissertation, the problem statement may be more practically oriented, identifying a specific organisational or industry challenge that the research will address. Many business dissertation problem statements draw on industry reports, company case studies or managerial challenges as well as academic literature to establish the problem’s significance.

In a health sciences dissertation, the problem statement typically establishes a gap in clinical evidence, a health inequality, an under-researched patient population or an inadequately evaluated intervention. It draws heavily on epidemiological data, NHS reports and systematic review literature.

In a humanities dissertation, the problem statement is often framed as a critical or interpretive gap — an aspect of a text, period or cultural phenomenon that existing scholarship has overlooked, misread or left unresolved. The “problem” is intellectual rather than practical but is no less real: it identifies where the scholarly conversation has failed to produce adequate understanding.

Problem Statement vs Research Question vs Rationale: Key Distinctions

Students sometimes conflate the problem statement with related concepts such as the research question and the rationale. Understanding these distinctions helps you write each more clearly and ensures your introduction chapter hangs together coherently.

The problem statement identifies what is wrong, absent or insufficiently understood about the current state of knowledge or practice. It establishes the necessity of the research. It is the “why this research is needed” section.

The research questions specify what your study will investigate in order to address the problem. They translate the problem into specific, answerable questions. Where the problem statement is broad and contextual, research questions are focused and direct. The research questions should follow logically from the problem statement — if the problem is X, your research questions ask how, why or to what extent X occurs, and what can be done about it.

The rationale explains the significance of the research — why it is worth doing, who will benefit from the findings, and what contribution it will make. Where the problem statement establishes what is missing, the rationale argues that filling the gap is worthwhile. Many dissertations combine the problem statement and rationale within the same introduction section.

Structuring and Writing a Strong Problem Statement

A strong problem statement typically follows a progression from the broad to the specific: from the general context and significance of the subject area, through the current state of knowledge or practice, to the specific gap, problem or inadequacy that the research will address. A useful mnemonic for this structure is the “inverted triangle”: start broad, narrow progressively, arrive at the specific problem.

The following components are typically included in a strong dissertation problem statement:

The broader context — What is the general subject area and why does it matter? This contextualises the problem within a wider landscape. Keep it brief — two or three sentences are usually sufficient.

The specific issue — What specific phenomenon, situation, challenge or knowledge gap is the focus of this research? Be precise. A specific issue is one that can be stated in a single sentence.

Evidence of the problem — Cite evidence that the problem is real, significant and not already resolved. This might include statistics, published findings, policy documents, news reporting on persistent issues, or statements by authoritative bodies. The quality of this evidence directly affects the credibility of the problem statement.

The consequences of the problem — Why does the problem matter? Who is affected and how? What are the practical or intellectual costs of leaving it unaddressed? This establishes urgency and significance.

The gap in current responses — Why is existing research, policy or practice insufficient to address the problem? This is where you establish that your research is genuinely needed rather than redundant. Draw on your preliminary literature review to identify specific limitations in existing work.

Frequently Asked Questions

What is a problem statement?
A concise description of the specific problem or gap your research will address and why it matters.

What should a problem statement include?
Context, the specific problem, evidence it matters, its consequences, and a bridge to your aim.

How long is a problem statement?
Usually a paragraph or two — focused, not lengthy.

How is it different from a research question?
The problem statement defines the issue; the research question asks what you will investigate about it.

How is it different from a rationale?
A rationale argues why the study is worth doing; the problem statement defines the problem itself.

Where does a problem statement go?
Usually early in the introduction, after the background.

Should a problem statement use evidence?
Yes — ground it in the literature or data to show the problem is real.

What is the most common mistake?
Being too broad or failing to show why the problem matters.

How long should a problem statement be in a UK dissertation?
A problem statement in a UK dissertation is typically one to three paragraphs within the introduction chapter, usually ranging from 150 to 400 words. Postgraduate dissertations may have more extended problem statements, particularly when the literature gap requires more detailed contextualisation. It should be concise and focused rather than exhaustive.

Can I write my problem statement before I have done my literature review?
You can write a preliminary problem statement based on your initial reading and the rationale for your research, but it should be revised and refined once your literature review is complete. The literature review often reveals the precise nature of the gap more clearly than initial reading suggests, and a good problem statement should reflect this precision.

Does a problem statement need references and citations?
Yes — the evidence used to establish that the problem is real should be cited from credible academic or authoritative sources. Statistics used to describe the scale of the problem, findings cited to establish what is currently known, and references to existing research limitations should all be cited appropriately.

What makes a problem statement too vague or too broad?
A problem statement is too vague if it could apply to thousands of different studies (“Mental health is a significant issue in the UK”). It is too broad if no single dissertation could realistically address it (“This research will examine all factors affecting educational attainment in UK schools”). A strong problem statement is specific, focused and clearly points towards a particular type of investigation with a manageable scope.

What is the difference between a problem statement and a purpose statement?
A problem statement identifies and describes the problem to be investigated — it is backward-looking in the sense that it explains why a gap or issue exists. A purpose statement describes what the research intends to do — it is forward-looking. Typical phrasing: “The purpose of this study is to…” Many UK dissertations include both, with the purpose statement appearing immediately after the problem statement in the introduction.
