The treatment of Body Dysmorphic Disorder (BDD) has received little empirical attention despite evidence that BDD is a debilitating mental health problem. This open case series provides data on a new cognitive-behavioral treatment for BDD. Participants diagnosed with BDD were treated in small groups that met for 12 weekly 90-minute sessions. Patients improved significantly over the course of treatment, with reductions in both BDD and depression symptoms. This finding adds to a nascent literature documenting the potential efficacy of short-term cognitive-behavior therapy for patients suffering from BDD.
