Book excerpt: This book provides a comprehensive overview of research into dissociation in children and adolescents and challenges conventional ideas about complex behaviours. Offering a new perspective to those who are unfamiliar with dissociation in children, and challenging prevalent assumptions for those who are experienced in the field, the editors encourage the professional to ask questions about the child’s internal experiences beyond a diagnosis of the external symptoms. Chapters bring together a range of international experts working in the field, and interweave theories, practice, and challenging and complex case material, as well as identifying mistakes that therapists can avoid while working with children who dissociate. Filled with practical tools and examples, this book is a vital resource for professionals to enrich their practice with children who dissociate.
