Dissociation is a common consequence of traumatic injury. It is a symptom in many psychiatric disorders and is often associated with severe symptomology and dysfunction. It can be successfully resolved if recognized and appropriately treated, yet few clinicians have received the needed training in evidence-based assessment and treatment of trauma-related dissociation. Failure to correctly diagnose and treat trauma-related dissociation can lead to prolonged suffering and levies a range of costs to patients and their loved ones, as well as the health care system and society at large. This book provides a concise yet comprehensive overview of trauma-related dissociation. Author Bethany L. Brand surveys common issues around misdiagnosis, provides a systematic review of methods for assessing dissociation, and shows providers how to use assessment results to guide treatment. She examines current theoretical conceptualizations of trauma-related dissociation and the psychological disorders of which it is a key symptom, and summarizes etiological theories of dissociation and issues specific to the assessment and treatment of children and adolescents. Throughout, Brand cites cutting-edge research that mental health providers must understand in order to successfully assess and treat this underserved population.
