Tens of thousands of clinicians have used this book—now revised and expanded with 50% new material—to plan and organize effective interventions for children and adolescents who have experienced complex trauma. The Attachment, Regulation, and Competency (ARC) framework can be used with children, parents, and other caregivers in a wide range of settings. The volume guides the clinician to identify key treatment goals and intervene flexibly to strengthen child–caregiver relationships and support healthy development and positive functioning. In a large-size format for easy photocopying, it is packed with case vignettes and clinical tools, including 79 reproducible handouts and forms. Purchasers get access to a webpage where they can download and print the reproducible materials.
