Both mindfulness-based stress reduction (MBSR) and present-centered group therapy (PCGT) led to significant improvement in PTSD symptoms among U.S. military veterans, as measured by the clinician-administered CAPS-IV scale, with no statistically significant difference between the two treatments. However, the MBSR group showed a statistically significant improvement in self-reported PTSD symptoms on the PTSD Checklist over the nine-week treatment period, though this difference was not maintained at the 16-week follow-up. The study involved 214 veterans randomly assigned to eight weeks of either 90-minute group MBSR or PCGT. Strengths include a large sample and multisite design; limitations include high attrition and low representation of women.
