The second, completely revised and updated edition of this handbook presents the current evidence-based psychological treatments for trauma-related disorders in childhood and adolescence. In addition, it provides clearly structured, up-to-date information on the fundamental principles of traumatic stress research and practice in this age group, covering epidemiology, developmental issues, pathogenetic models, diagnostics, and assessment. Each of the chapters on treatment, which form the core of the book, begins with a summary of the theoretical underpinnings of the approach, followed by a case presentation illustrating the treatment protocol session by session, an analysis of special challenges typically encountered in implementing this treatment, and an overview of the current evidence supporting the treatment approach. An innovative new section has been added to address the needs of emerging populations, featuring four new chapters that delve into the treatment of preschoolers, forcibly displaced children and adolescents, sexual and gender minorities, and indigenous populations. A special section considers treatments in particular settings, such as schools, hospitals, and juvenile justice systems. The concluding chapter provides an integrative discussion on how to effectively treat traumatized children and adolescents and an outlook into future developments. This book will be invaluable for clinical child and adolescent psychologists, child and adolescent psychiatrists, psychotherapists, and other mental health professionals dedicated to the care of traumatized children and adolescents.
