A handy, easy-to-read reference for the diag- nosis and treatment of posttraumatic and acute stress disorders,  this important 6th  edition has been revised and updated exten- sively, offering a wealth of new information in a concise format. The new DSM-5 diagnos- tic criteria for PTSD and ASD are discussed in depth. Updated tables listing instruments for assessing diagnosis and symptom severity are presented.   Chapters 3-5 have been revised to keep pace with the ever-expanding literature on treatment of PTSD with specific attention to evidence-based cognitive-behavioral therapy,  CBT, and other individual psychosocial treatments (e.g. eye movement desensitization and reprocessing, EMDR) as well as  the growing literature on couples, family, group and school-based treatments. Chapter  5 reviews the pathophysiology of PTSD and evidence-based pharmacotherapy for the disorder.  Chapter 6 then addresses both normal acute stress  reactions and clinically significant ASD,  as well as  effective interventions for each. In short this comprehensive, sophisticated, practical, guide is designed for all practitioners who wish to provide the best treatment for PTSD and ASD.
