This book presents an innovative relational and community based therapeutic model to ensure children's essential attachment needs are catered for in intensive mental health care. The text combines an overview of theory relating to attachment and trauma before laying out a model for working with children and adolescents in an attachment-informed way. The approach applies to a diverse range of settings - from in-patient psychiatric settings, through to schools-based programs, and provides the reader with the knowledge and guidance they need to introduce the approach in their own service. It also addresses the complexities of working with specific clinical populations, including children with ADHD, ASD, RAD and psychosis. Accessible for entry level clinical caretakers, yet sophisticated enough for clinical supervisors, this book is essential reading for professionals looking to improve the effectiveness of child and adolescent treatment programs.
