Brief Summary

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

Posttraumatic stress disorder (PTSD) is a major health problem for the nation's Veterans, leading to significant physical and mental health morbidity and mortality. Current empirically-supported interventions ameliorate symptoms but generally do not restore full functioning, so the development of alternative or complementary approaches is a critical need. Large numbers of Veterans are seeking out yoga as a part of their recovery plans, but there is not enough evidence to recommend yoga for treatment of PTSD. Likely reflecting this heterogeneity, evidence of yoga's efficacy is highly variable. This project aims to address this problem by comparing the effect of yoga to a matched exercise control condition. The study will also explore the mechanisms by which yoga impacts PTSD. Ultimately, the goal of this research would be to contribute to integrative care planning, whereby multiple approaches can be applied in a synergistic manner to restore wellness for Veterans affected by PTSD.

Detailed Description

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

Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition with a broad negative impact on physical and mental health functioning. Excellent, empirically-supported interventions for PTSD are readily available to Veterans, but the majority of patients who receive the best available treatments continue to have a diagnosable disorder after treatment. This suggests that complementary interventions may be useful to fully restore functioning. In addition, many patients seek alternatives to psychotherapy or pharmacotherapy. This is evident in the increasing numbers of individuals with PTSD are turning to alternative approaches. At present, however, the investigators lack a good evidence base from which to make recommendations about the use of complementary and alternative approaches.

Yoga is very popular practice, touted to enhance physical, mental and spiritual well-being. Many Veterans with PTSD have turned to yoga as a part of their recovery plan, often seeking care outside the specialty mental health system. Initial evidence suggests that the practice leads to clinically significant change in symptoms, but results are yet inconclusive, particularly in Veterans. Thus, this project will provide additional data as to efficacy of yoga for Veterans PTSD.

The study is a randomized controlled trial involving approximately 100 Veterans with PTSD from the San Diego area. These Veterans will be randomized to receive a manualized hatha yoga intervention or a supportive exercise control condition. Both interventions will be delivered by trained instructors via livestreaming or recorded classes over a 12-week period. Assessment of clinical outcomes and methodological variables will take place before, during, immediately after, and 3-months after the intervention. Analyses will focus on change in the intervention groups over time and the degree to which change is associated with the candidate mechanisms.

Results of this study have the potential to inform the way in which yoga is delivered to Veterans as well as to increase knowledge about the underlying processes by which PTSD can be ameliorated. Given the high demand for yoga demand by individuals with PTSD and the degree to which the practice is already being provided in many clinical settings, findings from this study will be immediately relevant. Findings may also guide future research in complementary and alternative approaches by demonstrating the principle of targeting different processes of change to create an integrative care plan.
