Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The central question in this research proposal is: can a popular technique that specifically targets active mastery and improved affect regulation, yoga, which is utilized by approximately 4% of the US population each year (1), improve the constellation of PTSD symptoms, multiple somatic complaints, social and occupational impairment and high health care utilization that has been documented in hundreds of thousands of women in the US?

The Primary Aims of this study include the following:

1. To test the short-term and long-term effectiveness of 10 weeks of yoga for treating treatment-resistant PTSD and compare it with attention controls receiving Women's Health Education (WHE).
2. To assess the short-term and long-term effects of yoga on a) co-morbid conditions, b) quality of life, c) body awareness, d) health care utilization and e) heart rate variability (HRV), in comparison to an attention control group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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." \[The study of yoga for chronic PTSD is in line with the empirical research that supports the notion that autonomic dysregulation plays a significant role in the persistence of PTSD (4), and with the hypothesis that an increased capacity for self-regulation is associated with a decrease in the severity of this symptom constellation\].

Primary aims.

1. To test the short-term and long-term effectiveness of 10 weeks of yoga for treating treatment-resistant PTSD and compare it with attention controls receiving Women's Health Education (WHE).
2. To assess the short-term and long-term effects of yoga on a) co-morbid conditions, b) quality of life, c) body awareness, d) health care utilization and e) heart rate variability (HRV), in comparison to an attention control group.

Primary Hypotheses:

1. Participants in the yoga condition will demonstrate a clinically significant reduction in PTSD symptoms at post-treatment, defined as a mean reduction of total CAPS score of at least 30% compared to baseline.
2. Yoga will be more effective than attention control at improving PTSD symptoms as evidenced by a significantly greater drop in total CAPS score from pre-treatment to post-treatment for the yoga group.

Secondary Hypotheses:
3. Yoga will be more effective at improving comorbid conditions and quality of life and reducing health care utilization than attention control.
4. Yoga will be more effective than attention control at improving HRV and body awareness.\]
