The efficacy of randomised controlled trials of cognitive behaviour therapy for perfectionism: a systematic review and meta-analysis.

Perfectionism is a transdiagnostic process across anxiety, depression, and eating disorders. The aim of this systematic review was to examine the efficacy of self-help and face to face CBT for perfectionism in reducing perfectionism and anxiety, depression, and eating disorders. A total of 15 randomised controlled trials of CBT for perfectionism were identified ( = 912 participants; mean pooled age = 23 years) which met inclusion criteria.
