Trichotillomania
Conditions
Brief summary
Objective: Trichotillomania is a psychiatric condition characterized by chronic pulling and plucking of one's own hair. Cognitive behavioral therapy shows promise as a treatment. However, there have been no randomized, controlled studies of the efficacy of group cognitive-behavioral therapy. Methods: We evaluated 44 subjects, whom met the criteria for a diagnosis of trichotillomania. Subjects were randomized to receive 22 sessions of either group cognitive-behavioral therapy or group supportive therapy (control).
