Abstract

Group-based exposure therapy (GBET) is an intensive group treatment that targets posttraumatic stress disorder (PTSD) symptoms through repeated imaginal and in vivo exposure. The purpose of the present study was to assess the feasibility and acceptability of a modified 12-week course of GBET (modified from the standard 16 weeks) and to examine its effectiveness in reducing veterans' PTSD symptoms. Participants were 10 male Operation Iraqi Freedom and Vietnam-era veterans recruited from a PTSD specialty clinic at a large Veterans Affairs Medical Center. All participants were retained and demonstrated clinically significant reductions in PTSD symptoms (η2 = .84–.87) comparable to the standard protocol. The findings from this small sample indicate that the abbreviated 12-week GBET protocol is a potentially effective treatment for PTSD.
