There is an ongoing need for empirically based treatments for child sexual abuse (CSA) that are time-efficient and cost-effective. This article describes a modification of cognitive processing therapy for child sexual abuse (CPT-SA) that increases the therapy's usability by reducing the number of individual therapy sessions required. The modifications are based on the developing literature on stage-based approaches to the treatment of CSA and incorporate dialectical behavior therapy skills training into the treatment protocol. Initial pilot data (N = 6) on modified CPT-SA suggests the therapy may be effective for the treatment of posttraumatic stress disorder (PTSD) and depression. (Contains 2 tables.)
