Even seasoned clinicians can feel deskilled when trying to help to highly traumatized and dissociative patients. Together, this book and its accompanying workbook for patients provide an evidence-informed, pragmatic, and compassionate approach to the stabilization and treatment of complex trauma and dissociation. These books will help clinicians immediately implement ways to assess and treat traumatized individuals with a comprehensive therapeutic program that includes session-by-session Information Sheets and Exercises developed through the process of synthesizing decades of clinical experience, the results of the Treatment of Patients with Dissociative Disorders (TOP DD) studies, and feedback from individuals living with trauma-related disorders. Traumatized individuals who participated in the program as part of the TOP DD Network study were better able to manage emotions in healthy ways and reduced their levels of dissociation, posttraumatic stress symptoms, and self-injury. This book provides guidance on how to use the program in individual and group contexts, as well as expert recommendations for assessing dissociation and clinical vignettes that focus on how to overcome common obstacles in trauma treatment. The companion workbook includes the patient-facing Information Sheets and Exercises that are the foundation for the Finding Solid Ground program. Together, these books present a coherent, comprehensive approach to trauma treatment that rests upon a clearly articulated understanding of the neurobiological impacts of trauma. Clinicians of all levels of experience will find these books inspiring, informative, and accessible.
