How to Write a Critical Review of a Journal Article (Step-by-Step)

To write a critical review of a journal article, you summarise the article briefly, then evaluate its strengths and weaknesses: the research question, methods, results, interpretation and contribution to the field, using evidence and recognised appraisal criteria. Finish with an overall judgement of how reliable and useful the article is. This guide explains how to write a critical review of a journal article step by step, with a reading strategy, a structure and example sentences.

What is the purpose of a critical review?

A critical review (also called an article critique or critical appraisal) tests whether you can judge research, not just describe it. Your marker wants to see that you can:

• Identify what the authors set out to do and whether they achieved it.
• Judge whether the methods were appropriate and rigorous.
• Decide whether the conclusions are supported by the data.
• Place the article in the context of wider literature.
• Explain what the findings mean for practice, policy or future research.

"Critical" does not mean negative. A good critique recognises genuine strengths as clearly as it identifies weaknesses. If you want a refresher on evaluative thinking in general, see critical analysis in assignments.

A three-pass reading strategy

Reading a research article once, front to back, is rarely enough. Use three passes instead.

1. First pass (10 to 15 minutes): get the big picture. Read the title, abstract, introduction headings, figures and conclusion. Note the research question, the design and the main finding.
2. Second pass (45 to 60 minutes): understand the detail. Read the whole article carefully. Highlight the aims, sample, methods, key results and limitations the authors admit. Look up unfamiliar terms and statistical tests.
3. Third pass (30 to 60 minutes): critique. Work through the article section by section with an appraisal checklist. Ask what is missing, what is assumed and what alternative explanations exist. Write notes under "strengths" and "weaknesses" as you go.

By the end of pass three, you should be able to state your overall judgement in one sentence before you start writing.

Questions to ask in each section

Use this table as your critique checklist. It works for most empirical articles in any discipline.

Critical appraisal tools

Using a recognised appraisal tool makes your critique systematic and gives your judgements authority.

CASP checklists for health and nursing

The Critical Appraisal Skills Programme (CASP) publishes free checklists for different study designs, including randomised controlled trials, systematic reviews, cohort studies, case control studies and qualitative studies. Each checklist asks questions under three broad areas:

• Validity: are the results of the study valid?
• Results: what are the results?
• Applicability: will the results help locally or in practice?

Choose the checklist that matches the study design. Using the RCT checklist on a qualitative study is a common mistake that markers notice. Other widely used tools in health include the JBI critical appraisal checklists. If your module names a specific tool, use that one.

General criteria for other subjects

Outside health, you can apply general criteria such as:

• Credibility: author expertise, journal quality, peer review.
• Rigour: suitability of design, sampling and analysis.
• Validity and reliability (quantitative) or trustworthiness (qualitative): would the findings hold up?
• Relevance: does the study still matter, and does it apply to your context?
• Contribution: what does it add to the field?

If you are unsure about design differences, our guide to quantitative vs qualitative research explains how quality is judged in each.

Journal article review structure

A typical journal article review structure for a 1,500 word critique looks like this. Adjust the percentages for your word count and follow any structure your brief specifies.

Notice that the summary is short. The biggest mistake in an article critique is spending half the word count describing the paper.

Article critique example sentences

Evaluative language shows your judgement. Here are article critique example sentences you can adapt:

Identifying strengths

• "A key strength of the study is its use of a validated measurement tool, which increases confidence in the reliability of the findings."
• "The authors justify their sampling strategy clearly, linking it to the research question."

Identifying weaknesses

• "The relatively small, single-site sample limits the extent to which the findings can be generalised."
• "Although the authors acknowledge response bias, they do not explain how it was addressed."

Weighing evidence

• "While the results are statistically significant, the effect size is small, which raises questions about practical significance."
• "These findings are consistent with [Author, Year], but contrast with [Author, Year], possibly because of differences in setting."

Overall judgement

• "Overall, the study makes a useful contribution, although its conclusions should be treated with caution until replicated in a larger sample."

Always back each judgement with evidence from the article or other literature. An unsupported "this study is weak" earns few marks.

How to write a critical review of a journal article, step by step

1. Check the brief: required structure, appraisal tool, word count and referencing style.
2. Read the article three times using the strategy above.
3. Complete an appraisal checklist and note page numbers as evidence.
4. Find two to five related studies to compare against.
5. Decide your overall judgement before drafting.
6. Write the summary briefly, then the critical evaluation in detail.
7. Link to practice or future research in your wider context section.
8. Proofread and check references, including the full reference for the article itself.

Common mistakes to avoid

• Describing the article instead of evaluating it.
• Being only negative, or only positive.
• Criticising things the study never aimed to do.
• Using the wrong appraisal checklist for the study design.
• Making claims about statistics without understanding them.
• Ignoring the limitations the authors already acknowledged (engage with them instead).
• Forgetting to compare the article with other research.

Frequently asked questions

What is the difference between a summary and a critical review?

A summary describes what the article says: its aim, methods and findings. A critical review goes further by evaluating how well the study was done, whether its conclusions are justified and how useful it is. A short summary is only one part of a critical review.

What is a CASP checklist?

CASP checklists are free critical appraisal tools from the Critical Appraisal Skills Programme. There are separate checklists for different study designs, such as RCTs, qualitative studies and systematic reviews, and each guides you through questions on validity, results and applicability.

Should I use "I" in a critical review?

It depends on your module. Many health and social science courses accept limited first person ("I would argue"), while others prefer impersonal phrasing ("this review argues"). Check your brief or ask your tutor.

How many other sources should I use in an article critique?

There is no fixed rule, but most critiques use a handful of related studies and methods texts to support their judgements. Check your brief, because some critiques are expected to focus almost entirely on the single article.

How long should a critical review of a journal article be?

Most are between 1,000 and 2,500 words. Whatever the length, aim to spend at least half of your word count on critical evaluation rather than summary.
