Research has demonstrated a close association between trauma exposure and 1) PTSD, anxiety & depression, 2) loss of affect regulation, 3) poor quality of life, and 4) high health care utilization (2, 3). This study will explore how a popular body-mind technique, yoga, compares with a attentional control group condition, Women's Health Education (WHE), in the treatment of [heretofore treatment- unresponsive adults with] PTSD, and measure whether yoga can affect "the attitudes and beliefs" that "can reduce psychological stress and contribute to positive health outcomes." [The study of yoga for chronic PTSD is in line with the empirical research that supports the notion that autonomic dysregulation plays a significant role in the persistence of PTSD (4), and with the hypothesis that an increased capacity for self-regulation is associated with a decrease in the severity of this symptom constellation].
