The Evidence

Many scientific studies of the cognitive behavioural treatment for perfectionism have been conducted. Together they provide strong research evidence that the treatment is effective at improving perfectionism. The treatment also improves anxiety, depression, and disordered eating. The research shows that the treatment is effective when people have the help of a therapist but also if they use the self-help book either alone or with support. It is effective when delivered in schools or in groups, and for all different ages.
