Mindfulness-Based Stress Reduction (MBSR) programs are becoming more integrated into the treatment of persons with substance use disorders (SUDs). A focus of MBSR is to increase awareness of sensations in the body and accept them in the moment without judgment. Little is known about the readiness of women, with posttraumatic stress disorder (PTSD), and their level of comfort to participate in MBSR programs. Habermas' ideal speech situation guided a cooperative inquiry with 45 women at 3 treatment centers. Women engaged in activities of MBSR and shared opinions on how to develop a manual that would address the readiness of women with SUDs-PTSD to participate in MBSR.
