This retrospective chart review evaluates the effectiveness of manualized cognitive processing therapy (CPT) protocols (individual CPT, CPT group only, and CPT group and individual combined) and manualized prolonged exposure (PE) therapy on veterans' posttraumatic stress disorder (PTSD) symptoms in one Veterans Health Administration (VHA) specialty clinic. A total of 517 charts were reviewed, and analyses included 178 charts for CPT and 85 charts for PE. Results demonstrated CPT and PE to significantly reduce PTSD Checklist (PCL) scores. However, PE was significantly more effective than CPT after controlling for variables of age, service era, and ethnicity. Additional findings included different outcomes among CPT formats, decreased treatment dropouts for older veterans, and no significant differences in outcome between Hispanic and White veterans. Study limitations and future research directions are discussed.
