A handy, easy-to-read reference for the diagnosis and treatment of posttraumatic and acute stress disorders, this important 6th edition has been revised and updated extensively, offering a wealth of new information in a concise format of 6 sections. The new DSM-5 diagnostic criteria for PTSD and Acute Stress Disorder (ASD) are discussed, in depth, in Chapters 2 and 6, respectively. In addition, updated tables listing instruments for assessing diagnosis and symptom severity are cited and annotated in seven appendices, as in previous editions. Chapters 3-5 have been revised to keep pace with the ever-expanding literature on treatment of PTSD. This is especially true in Chapter 4 where, in addition to a focus on evidence-based cognitive-behavioral therapy, CBT and other individual psychosocial treatments (e.g. eye movement desensitization and reprocessing, EMDR), the growing literature is presented on couples, family, group and school-based treatments for adults, children and adolescents. Chapter 5 reviews the pathophysiology of PTSD and evidence-based pharmacotherapy for the disorder. Chapter 6 addresses both normal acute stress reactions and clinically significant ASD, as well as effective interventions for each. A comprehensive, sophisticated, practical reference for all clinicians, Posttraumatic and Acute Stress Disorders, 6th Edition is an invaluable resource designed to guide the best clinical attention for individuals suffering from posttraumatic and acute stress disorders.
