Obsessive-compulsive disorder (OCD) affects approximately one in a hundred young people, and often makes it difficult to lead happy and productive lives. Structured as a flexible 14-session programme, this workbook is intended to be used in conjunction with the clinical manual for this title, OCD - Tools to Help Young People Fight Back. It sets out an evidence-based treatment for young people with OCD using Cognitive Behavioural Therapy and Exposure and Response Prevention techniques. Designed to be employed in a clinical setting, it uses simple diagrams and illustrations to explain ways to cope with OCD thoughts and behaviours, and provides activities for use both within sessions and at home. The fun and engaging way in which the exercises are designed will encourage the patient to fully involve themselves in the recovery process and overcome their OCD. An essential resource for clinicians treating young people affected by OCD, this workbook brings together the patient, the therapist and the patient's family to fight OCD as a team.
