This will be a 5-session version of a group CBT protocol with 4-6 patients and 2 therapists per group emphasizing repeated exposure practices. Session 1 involves an introduction and orientation to the CBT model. Sessions 2-5 emphasize repeated exposure tasks, which consist of role-play activities to confront fearful situations in a group setting while disputing cognitive distortions (coupled with the fading of safety behaviors). At the conclusion of each exposure session, patients will be encouraged to continue to apply home-practice strategies (such as giving speeches in front of a mirror). Continued practice of the interventions will be considered part of treatment, and patients will be asked to refrain from alternative treatment for four weeks following completion of the last treatment session.
