This fully revised and updated second edition includes new techniques from ‘third’ wave CBT, Acceptance Commitment Therapy (ACT) and Dialectical Behaviour Therapy (DBT).This enriches the material and brings the concepts up to date.Another key addition to this new edition is the inclusion of strategies for young people who engage in suicidal behaviour.The manual is evidence based and focuses on a flexible and formulation driven model to direct treatment in around 15 sessions for young people and six sessions for parents and caregivers.It provides a clear structure for each session and an easy-to-follow outline on how the therapist should deliver each session.The content of each session is supported by handouts and worksheets which can be used within sessions or as homework between sessions. Enhanced with online resources, the workbook will be useful for all professionals working with young people who self-harm across a wide range of settings from schools, primary care and voluntary sector, to community mental health services and inpatient units.
