The Yale-Brown Obsessive Compulsive Scale Modified for Body Dysmorphic Disorder (BDD-YBOCS) is a 12-item, semi-structured, rater-administered measure that assesses body dysmorphic disorder severity during the past week. Scores for each item range from 0 (no symptoms) to 4 (extreme symptoms); the total score ranges from 0 to 48, with higher scores reflecting more severe symptoms.
Safety and Efficacy of Psilocybin for Body Dysmorphic Disorder
Brief Summary
In this pilot study 12 adult outpatients with body dysmorphic disorder that has not responded to at least one adequate trial of a serotonin reuptake inhibitor will be treated openly with a single oral dose of psilocybin. Followup visits to monitor safety and clinical outcome will be conducted over a 3 month period.

Location
In this pilot study, up to 12 adult outpatients with body dysmorphic disorder that has not responded to at least one adequate trial of a serotonin reuptake inhibitor will be treated openly with a single oral dose of psilocybin. Procedures will follow those previously established in depression studies of psilocybin. Patients will receive intensive preparation and support from two therapists, including 8-9 hours accompanying the patient on the day of medication administration in the Biological Studies Unit of New York State Psychiatric Institute. Followup visits to monitor safety and clinical outcome will be conducted at day 1, week1, and months 1,2, and 3 post-administration. Resting state function magnetic resonance imaging will be conducted prior to and one day after psilocybin administration to assess the effect of medication on brain circuits.
