Group Treatment for Trichotillomania: Cognitive-Behavioral Therapy Versus Supportive Therapy

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).
