Targeting perfectionism in anorexia nervosa using a group-based cognitive behavioural approach: a pilot study.

Objective: This study aimed to explore whether a six session cognitive behavioural group intervention targeting perfectionism is efficacious in reducing perfectionism in adults with anorexia nervosa in an inpatient setting.

Method: Adults with anorexia nervosa received a group perfectionism intervention in an inpatient setting. Self-report and patient satisfaction questionnaires were completed at the beginning of the first session and end of the last session.

Results: Significant changes of moderate effect size were observed for overall perfectionism, concern over mistakes and personal standards dimensions of perfectionism following participation in the group. These changes were found to be independent of change in body mass index.

Conclusions: A group cognitive behavioural approach appears to be efficacious in reducing perfectionism in adults with anorexia nervosa.
