Abstract
Objective: To introduce clinicians to the methodology and critical appraisal of randomized controlled trials (RCTs) in psychiatry.
Method: The methodology of RCTs in psychiatry is discussed. Using a systematic approach to critical appraisal, a published RCT of treatments for severe depression is examined and evaluated.
Results and Conclusions: The RCT appraised illustrates certain problematic areas in the methodology of trials in psychiatry. A detailed knowledge of methodology and critique of RCTs is essential in determining whether reported results will influence clinicians’ practice.
