 The purpose of the proposed study is to examine the effects of Cognitive-Behavioral treatments for PTSD on PTSD symptoms and relationship functioning in active duty military personnel who have recently returned from combat deployment to Operation Enduring Freedom OEF, Operation Iraqi Freedom OIF, or Operation New Dawn OND and their partners. Research indicates that PTSD is associated with high levels of relationship distress 8-12. We will compare a treatment specifically designed to incorporate partners, Cognitive-Behavioral Couples Therapy CBCT, with an established therapy that focuses on treatment of the individual, Prolonged Exposure PE. CBCT includes techniques designed both to promote support for the traumatized individual and reduce relationship distress; whereas, PE focuses solely on PTSD symptoms and treats only the patient with PTSD. Therefore, we expect to see greater improvement in intimate relationship functioning with CBCT than with PE, while remaining equally effective in reducing PTSD symptomatology. Our specific hypotheses are as follows:
