Brief Summary:
The purpose of this study is to examine whether group cognitive behavioral treatment (GCBT) is efficacious in the treatment of PTSD in a sample of male Veterans. Veterans with a primary diagnosis of chronic PTSD will be randomly assigned to either GCBT or a supportive group treatment condition. Both treatments will consist of 14, weekly sessions. Assessment of PTSD and related symptoms will be conducted at pre-treatment, mid treatment, post-treatment, and 3-, 6-, - and 12-month follow-up.

Detailed Description:
The mental health needs of Veterans within the VA Healthcare system are notable. With the substantial increase over the past 10 years in Veterans seeking Posttraumatic Stress Disorder (PTSD) treatment services, the VA system is straining to accommodate these needs, relying heavily on group-based treatments. The proposed research will take the next step in the literature on group psychotherapy for PTSD by examining a group cognitive behavioral treatment (GCBT) program with promising pilot data. This application supports a randomized controlled trial, which will compare GCBT with Supportive Group Psychotherapy (SGP). The trial will involve 196 male Veterans with combat-related PTSD who will be randomly assigned to GCBT (n= 98) or SGP (n =98) to determine efficacy within a naturalistic care environment. Outcome data will be collected pre-treatment, mid-treatment, post-treatment, and 3-, 6- and 12-month follow-up. Two aims are included, one focusing on outcome with respect to PTSD symptom severity, the second focusing on treatment generalization to comorbid emotional disorders (major depressive disorder, generalized anxiety disorder, and alcohol abuse), and distress and impairment. Data will be examined using latent growth curve modeling, with emphasis on determining efficacy and effectiveness. The information provided by the proposed project could assist in developing more effective care models for individuals with chronic PTSD from numerous traumatic experiences. Additionally, this project represents an effort to move the literature on group-based treatments for PTSD ahead, through inclusion of advanced methodological and analytic approaches.

Arm Intervention/treatment
Experimental: Arm 1
Group Cognitive Behavioral treatment (GCBT)
Behavioral: Group Cognitive Behavioral Treatment (GCBT)
GCBT is a 14 week intervention that includes components of exposure (imaginal and in vivo), cognitive restructuring, and relapse prevention.

Active Comparator: Arm 2
Present Centered Group Treatment
Behavioral: Present Centered Group Treatment
The active comparison treatment is a 14 week treatment that focuses on here and now problems, especially problem solving skills concerning ongoing stressors.

Primary Outcome Measures :
  1. Clinician Administered PTSD Scale (CAPS) [ Time Frame: 12 months ]
    The CAPS is a semi-structured interview to assess presence and severity of PTSD symptoms. The total score on the CAPS will be used as the primary outcome measure in this study.

Secondary Outcome Measures :
  1. Beck Depression Inventory, II (BDI-II) [ Time Frame: 12 months ]
    The BDI is a self-report inventory that indexes depression symptom severity.

  2. Short-Form Health Survey (SF-36) [ Time Frame: 12 months ]
    The SF-36 is a measure of functional impairment.

  3. Beck Anxiety Inventory (BAI) [ Time Frame: 12 months ]
    The BAI is a self-report measure of general anxiety symptom severity.
