The incidence of sexual assault and harassment experienced by members of the U.S. Armed Forces has reached epidemic proportions. Its victims often suffer from devastating, lifelong consequences to their careers, health, relationships, and psychological well-being. This book is written for mental health clinicians to help in understanding and treating military sexual trauma (MST). It addresses the complex circumstances of victims of sexual abuse in the military and how clinicians can meet the unique challenges of treating these clients. The book describes how MST differs from other forms of military trauma such as combat, and discusses its prevalence, neurobiology, and social contexts as well as unique stressors of betrayal, injustice, struggles with issues of reporting and disclosure, and impact on relationships and sexuality. It reviews current evidence-based interventions and offers insights on treating specific symptoms within MST, such as post-traumatic stress disorder (PTSD), anxiety, substance abuse, sleep disorders, and sexual dysfunction. Chapters discuss how a variety of psychotherapies can be used to treat MST, including prolonged exposure, cognitive processing, Eye Movement Desensitization and Reprocessing (EMDR), Seeking Safety, acceptance and commitment therapy, and somatic experiencing, as well as the Warrior Renew MST group therapy program. Clinicians who work with veterans and active duty personnel will find the book an essential guide to working with MST survivors.
