The Clinician’s Manual and its accompanying workbook, I Believe in Me, Not OCB! combine cognitive behavioral therapy and applied behavior analysis to treat obsessive-compulsive behavior (OCB) in children and youth with autism. The manual serves as a practical guide for therapists, beginning with chapters that explain the theoretical underpinnings of OCBs, adaptations for autism, and guidance on clinical and functional behavioral assessment that are key to administering the nine treatment sessions that follow. The workbook builds on this with hands-on exercises, and a vital worksheet where children specify coping techniques, exposure steps, and reinforcers given at home. Together, this powerful bundle provides comprehensive strategies for understanding and addressing obsessive-compulsive behaviors through evidence-based approaches. It will provide valuable insights, practical techniques, and supportive frameworks to foster independence and self-confidence in those you support.
