Treatment Development Study of the COMB Model of Trichotillomania

Brief Summary

      This pilot study is being conducted in order to help make the case for later, more systematic
      research on the effectiveness of the Comprehensive Behavioral (COMB) model of treating
      trichotillomania (compulsive hair pulling). The goals are to standardize COMB treatment
      techniques in the form of a clear written manual for therapists; determine whether therapists
      can use these guidelines in a consistent manner in making treatment decisions; develop and
      test the reliability of measures of how well therapists are conducting the treatment; and
      collect preliminary data on the acceptability of the treatment to patients.
