This book is a comprehensive evidence-based guide for clinicians and trainees on the assessment and treatment of youth with obsessive-compulsive and related disorders (OCRDs).

OCRDs typically begin in childhood or adolescence and can be highly prevalent and impairing, though there has been minimal clinical guidance on treatment of such disorders in youth. This go-to handbook on OCRDs in childhood has an international range of expert contributors providing evidence-based guidance on assessment and treatments of these conditions including adapting treatment for very young children, digital mental health interventions, and family-based, parent-based, and intensive treatment formats. Chapters also review other field areas such as clinical presentation, causal and maintaining factors, and features and transdiagnostic psychological dimensions of ORCDs. The concluding chapters discuss future directions for the field and emphasize the need for diversity, dissemination, and implementation in childhood OCRD research.

This book is essential for clinicians specializing in OCD and related disorders in children and adolescents. It is also applicable to clinicians, trainees, and students across a wide range of mental health disciplines.
