Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
170 male, Vietnam era veterans referred for PTSD treatment were informed about the study, 98 consented to participate, 11 dropped out before randomized, 6 were excluded due to (3)psychosis or manic symptoms and 3 did not have PTSD. 40 were assigned to PSGT and 41 to GBET. One assigned to GBET, dropped out during the first week and was replaced.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants had been referred to an outpatient PTSD program, were first screened by the staff of that program and if judged to be appropriate for intensive PTSD treatment were informed about the study. They could request to be screened for the study or go directly into one of the treatments provided by the PTSD program.

Reporting Groups
  Description
Group Based Exposure Therapy Group Based Exposure Therapy: GBET is a 16-week program during which patients attend group therapy twice a week for three hours of group per day and are required to make two war trauma presentations to their group. These are recorded and the patients are required to listen to these recordings a minimum of 10 times. There are generally 10 patients per group and through the combination of making their own presentations, listening to recordings of these presentations, and hearing the presentations of the other nine group members, there are over 60 hours of exposure. Patients also learn about PTSD symptoms, sleep hygiene, specific stress/anger management techniques, and ways to cognitively restructure trauma-related thinking.
Present Centered Group Therapy Present Centered Group Therapy: Present Centered Group Therapy includes psych-education about PTSD and a problem solving "here and now" focus.
