A Multisite Randomized Controlled Trial of Mindfulness Meditation Therapy for PTSD

MBSR is a manualized program involving 8 weekly classes and a single 6-hour silent retreat session based on a systematic procedure to develop enhanced non-reactive awareness of the moment-to-moment experience of perceptible mental processes.

The comparison control group will be PCGT, which was initially developed for use as a control group in a VA multi-site study that tested the effects of Trauma-Focused Group Therapy. Correspondingly, PCGT serves as a credible control for the nonspecific effects of a group-based intervention (i.e. controls for time, attention, expectation of recovery, and recognition of the illness).
