Trichotillomania (TTM) is a complex disorder that is difficult to treat, and few effective therapeutic options exist. This client workbook helps the client through the 10-session, therapist-guided, Acceptance and Commitment Therapy (ACT) Enhanced Behavior Therapy for Trichotillomania (AEBT-T). AEBT-T is designed to help people with trichotillomania reduce their pulling, think differently about the internal experiences that trigger their pulling, and learn to live a more valued life. The approach blends traditional behavior therapy approaches of habit reversal training and stimulus control techniques with a more contemporary ACT-based approach. This ACT-based approach teaches clients to behave flexibly and in concert with their values whenever they face the uncomfortable thoughts, feelings, urges, and cravings that often trigger the pulling. Since its original publication in 2008, the intervention has been shown to be highly effective, and can also be successfully applied to older children and adolescents, which is covered in this new edition. Fully updated to reflect new research and organized in an easy-to-use session-by-session format with accompanying therapy support forms and materials, AEBT-T has proven efficacy and will be a valuable resource and powerful tool for clients who want to learn to manage their TTM and reduce pulling.
