Writing a critical review - Questions to ask:
- Was the sample size big enough to allow findings to generalise to other populations?
- Did attrition affect the results?
- Were the inclusion criteria too wide or narrow?
- Were there flaws in the research design?
- Quantitative research: were participants randomly assigned to groups in a double blinded fashion? Was there a control group?
- Qualitative research: Were interview guides piloted? Were measures taken to enhance the credibility of data analyses? Do the researchers declare any personal biases that may have influenced their interpretation of results?
- Is the source credible? Is it a peer-reviewed journal or unknown website?
- When was the article published? Is it recent?
- Does the study explain the results (or simply just describe)?
- Has the author(s) considered how the results apply to wider populations or practice settings?
- Has the study addressed a ‘gap’ in the literature?
- Are the conclusions final or preliminary? What further research is required?
- Overall how good do you think the article is?
