The purpose of this study is to evaluate the equivalence of CPT treatment delivered remotely via telemental health (TMH) over videoconferencing or via traditional face-to face (FTF) treatment to veterans who have Post-traumatic Stress Disorder (PTSD) from a military-related stressor (i.e., combat, sexual assault, non-combat physical assault). The secondary objective is to determine if patients' ratings of PTSD symptoms, affect, social adjustment, therapy alliance, treatment satisfaction and therapist satisfaction, are equivalent between service-delivery conditions (TMH vs. FTF). A final objective is to develop web-based practice assignments to assist participants in the TMH condition with treatment adherence (completion of the between- session practice assignments).
