Brief summary

This project will primarily examine whether a group psychological treatment for clinical perfectionism is better than being on an eight-week waitlist in a) reducing individuals' levels of clinical perfectionism, b) reducing their symptoms of anxiety, depression, and/or eating concerns and c) improving their quality of life. It is predicted that the group treatment will lead to greater reductions in clinical perfectionism, greater reductions in psychological symptoms, and greater increases in quality of life compared to the waitlist control condition. Additionally this project will examine whether group psychological treatment for clinical perfectionism produces treatment-related change in each individual and whether this is clinically significant.

Interventions

Intervention: Group cognitive behavioural therapy for clinical perfectionism. In this intervention participants receive 8 x 2-hour sessions of group therapy over 8 weeks, where they learn strategies to reduce their clinical perfectionism. The strategies are derived from the book Overcoming Perfectionism: A Self-help Guide Using Cognitive Behavioural Techniques (Shafran, Egan & Wade, 2010).
