PE is a manualized, 90-minute, 8-15 week treatment program based on emotional processing theory, which posits that anxiety disorders, including PTSD, reflect pathological fear structures in which emotional and cognitive associations among different elements do not accurately represent reality and renders the individual dysfunctional and distressed. PE is designed to correct erroneous connections in the targeted memory structure. PTSD sufferers typically experience two key pathological emotional response sets and related cognitions: "The world is an utterly dangerous place," and "I am completely incompetent and unable to cope with stress." In this study, the 12-session protocol will be followed, but participants improve more rapidly may finish in 10 sessions and those who improve more slowly may have up to 2 additional sessions to continue working on exposure. | CPT consists of cognitive therapy and a written trauma narrative. Patients are taught to challenge their beliefs through Socratic questioning and the use of daily worksheets. The initial focus is on beliefs such as denial and self-blame, and then shifts to overgeneralized beliefs about self and the world. Patients process their trauma directly by writing a narrative of their traumatic event(s) that they read to themselves and to therapists. The typical protocol consists of 12 1-hr sessions. In this study, the 12-session protocol will be followed, but participants who improve more rapidly may finish in 10 sessions and those who improve more slowly may receive up to 2 additional sessions to continue working on stuck points with challenging beliefs worksheets. |

Measure Description: Treatment preference was assessed at baseline (before any treatment was administered, and before randomization to treatment arm had occurred). This measure is reported as the number of patients who reported a preference for PE as opposed to CPT. All unreported patients reported a preference for CPT (i.e., "no preference" was not a response option and no patients declined to answer).
