Although cases of posttraumatic stress disorder (PTSD) with comorbid disorders are common, the first generation of PTSD treatment approaches, including exposure and cognitive-behavioral therapy, generally ignore symptoms beyond those specific to PTSD. Optimum PTSD treatment outcome requires more comprehensive strategies, and the development and empirical testing of broader approaches is the focus of the articles that follow in this special issue. After providing some background on PTSD and PTSD treatment, this paper gives an overview of these treatment and prevention papers, which represent second-generation strategies to help trauma-exposed individuals.
