Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Estimates indicate that between 100,000 and 300,000 Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) veterans are at significant risk for chronic post-traumatic stress disorder (PTSD), which can become a chronic disorder that impacts all areas of a person's life. PTSD treatment programs are being developed throughout the Department of Defense (DoD) and the Veterans Affairs (VA), but because of the large number of Service Members returning from deployment with PTSD, it is often necessary to provide psychotherapy in groups. Cognitive Processing Therapy (CPT), an evidence-based treatment for PTSD, was originally developed as a group-based intervention. However, group-based CPT treatment has never been systematically compared to individual CPT treatment. The public policy implications of the results of this trial are significant. If both treatment formats are equivalent or if group treatment is better, then group treatment would be a more efficient and cost-effective therapy modality in most cases. On the other hand, if individual therapy is found to be superior, the investment of greater resources into individual therapy will be justified in order to provide the most effective treatment for PTSD to military personnel. The purpose of this study is to compare group-administered CPT-Cognitive-only version (CPT-C) to individual CPT-C for the treatment of PTSD in OIF/OEF military personnel. Three hundred (300) adult male and female active-duty OIF/OEF military personnel over 18 years of age will be enrolled into this study. Participants will be randomized between group and individual CPT-C.

Group Cognitive Processing Therapy-Cognitive Only

Group Type EXPERIMENTAL

Group Cognitive Processing Therapy-Cognitive Only

Intervention Type BEHAVIORAL

Cognitive Processing Therapy-Cognitive Only version (CPT-C) is an evidence-based form of Cognitive Behavioral Therapy (CBT) used to treat PTSD. CPT-C is a 12-session manualized program that focuses on challenging beliefs and assumptions related to the trauma, oneself, and the world. Sessions will be conducted in groups of 8-12 participants. Sessions will be conducted twice weekly for six weeks; each session is 90 minutes.

Individual Cognitive Processing Therapy-Cognitive Only

Group Type EXPERIMENTAL

Intervention Type BEHAVIORAL

Cognitive Processing Therapy-Cognitive Only (CPT-C) is an evidence-based form of Cognitive Behavioral Therapy (CBT) used to treat PTSD. CPT is a 12-session manualized program that focuses on challenging beliefs and assumptions related to the trauma, oneself, and the world. Individual sessions will be conducted twice weekly for six weeks; each session is 60 minutes.
