Acclaimed for providing a flexible framework for individualized treatment of posttraumatic stress disorder (PTSD), this empathic guide has now been revised and expanded with 50% new material. The authors show how the case formulation approach enables the practitioner to adapt CBT for clients with different trauma histories, co-occurring problems, and complicating life circumstances. Vivid clinical material illustrates the implementation of exposure therapy, cognitive restructuring, and supplemental interventions, with ample attention to overcoming common obstacles.
