Critical Appraisal

Critical appraisal is the process of carefully and systematically examining research to judge its trustworthiness, and its value and relevance in a particular context. Amanda Burls, What is Critical Appraisal?, Feb 2009

This page includes some useful resources to get you started with critical appraisal, or further reading if you have already attended training in the Warner Library.

Training:

“An Introduction to Critical Appraisal” will help you understand how to critically appraise a randomised Controlled Trial (RCT). Using the CASP Checklist the course covers samples and sample size, randomisation, bias, statistics, significance (P Values and Confidence Intervals) and relevance.

Training can also be arranged for departments,  teams or journal clubs. The research paper used for the appraisal can then be chosen to match the teams speciality.

Contact the Warner Library to arrange a date.
