Effect of a Motivation Enhancement Intervention on Veterans' Engagement in PTSD Treatment

This study is the first randomized controlled trial of the postraumatic stress disorder (PTSD) motivation enhancement (PME) Group, a brief intervention based on Motivational Interviewing and designed to enhance combat veterans' engagement in PTSD treatment by increasing awareness of the need to change PTSD-related problems. Outpatients in a year-long, group- and cognitive-behavioral therapy (CBT)-oriented Veterans Affairs PTSD treatment program were randomly assigned to 4 sessions of the PME Group (n = 60) or a Psychoeducation Group (n = 54) in the 2nd month of treatment. Hypotheses about the proposed impact of the PME Group on PTSD treatment engagement (i.e., readiness to change, perceived treatment relevance, and PTSD program attendance) were all supported, although predicted differences were not found on all measures. These results support the need to address readiness to change in combat-related PTSD treatment.
