Therapists around the world ask similar questions and struggle with similar challenges treating highly dissociative patients. This book arose not only out of countless hours of treating patients with dissociative disorders, but also out of the crucible of supervision and consultation, where therapists bring their most urgent questions, needs and vulnerabilities. The book offers an overview of the neuropsychology of dissociation as a disorder of non-realisation, as well as chapters on assessment, prognosis, case formulation, treatment planning, and treatment phases and goals, based on best practices. The authors describe:What to focus on first in a complex therapy and how to do itHow to help patients establish both internal and external safety without rescuingHow to work systematically with dissociative parts of a patient in ways that facilitate integration rather than further dissociationHow to set and maintain helpful boundariesSpecific ways to stay focused on process instead of contentHow to deal compassionately and effectively with disorganised attachment and dependency on the therapistHow to help patients integrate traumatic memoriesWhat to do when the patient is enraged, chronically ashamed, avoidant or unable to trust the therapistHow to compassionately understand and work with resistances as a co-creation of both patient and therapistRelational ways of being with the patient are the backbone of treatment and are themselves essential therapeutic interventions. As such, the book also focuses not only on highly practical and theoretically sound interventions, not only on what to do and say, but places strong emphasis on how to be with patients, describing innovative, compassionately collaborative approaches based on the latest research on attachment and evolutionary psychology. Throughout the book, core concepts—fundamental ideas that are highlighted in the text in bold so they can be seen at a glance—are emphasised. These serve as guiding principles in treatment as well as a summing-up of many of the most important notions in each chapter. Each chapter concludes with a section for further examination. These sections include additional ideas and questions, exercises for practising skills and suggestions for peer discussions based on topics in a particular chapter, meant to inspire further curiosity, discovery and growth.
