A Comparison of Cognitive Processing Therapy (CPT) Versus Present Centered Therapy (PCT) for Veterans

The purpose of this study is to compare the effectiveness of Cognitive Processing Therapy
(CPT) versus Present Centered Therapy (PCT) for male OEF/OIF Veterans with combat related
PTSD.

CPT has been shown to be effective in treating trauma survivors in several treatment outcome
studies, but utility with Veterans has only been examined with male Veterans in one small
pilot study. In addition CPT has never been compared to a treatment as usual or supportive
psychotherapy condition to control for the specific and nonspecific elements of treatment.
Although Cognitive Processing Therapy is one of the main treatment modalities at several
VA's, including Cincinnati, it has never been compared to PCT, nor has it been used in a
large, randomized study of male OEF/OIF Veterans. It is hypothesized that individual
receiving CPT will show a larger reduction in posttraumatic stress disorder and related
symptoms than those individuals receiving PCT.

All male OEF/OIF Veterans will be screened for their appropriateness for the study by phone
screen and then by an assessment technician. The Veteran will be assessed at pre, post,
3-month, and 1-year follow-up. The assessment technicians will be blind to the participant's
condition. CPT is a 12 week long individual psychotherapy treatment shown to be effective at
reducing PTSD and related symptoms for survivors of various types of traumas, including
combat. PCT is a supportive counseling treatment that has been utilized as an alternative to
waitlist control in VA cooperative studies of PTSD.
