Post-traumatic stress disorder (PTSD) is the most widespread mental illness resulting from exposure to combat, necessitating an increase in the provision of group therapy. This pilot study examined the efﬁcacy of, and treatment outcome predictors associated with, group inpatient treatment of combat-related PTSD. Participants included 38 active duty military personnel deployed during Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF), diagnosed with PTSD, and consecutive admissions to an inpatient PTSD treatment facility. A paired samples t-test revealed signiﬁcant change in symptom severity and global functioning between pre- and post-treatment. Multiple regression analyses supported the predictive utility of baseline symptomatology and group cohesion (> 50% of the variance in treatment outcome), highlighting the importance of group cohesion in the efﬁcacy of group treatment for combat-related PTSD.
