This study evaluated the effect of comorbid personality disorders on treatment outcome for male and female Veterans with posttraumatic stress disorder (PTSD). One hundred and sixty-six Veterans participated in a PTSD Residential Rehabilitation Program, which included cognitive processing therapy (CPT) provided in a combined individual and group format. Sixty-six percent of participants met criteria at pre-treatment for at least one personality disorder. No difference was found between participants with and without personality disorders on pre-treatment demographic variables, self-reported PTSD symptoms, or clinician-assessed PTSD symptoms. However, differences were found between the groups on self-reported depression symptoms. When controlling for pre-treatment self-reported depression symptoms, results indicated that both groups had significant reductions on PTSD outcome measures, regardless of the presence of a personality disorder. Additionally, a comparable number of participants with and without personality disorders no longer met criteria for PTSD following treatment. Findings suggest that Veterans with personality disorders can benefit from a CPT-based PTSD residential program.
