Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Clinician Administered PTSD Scale for Diagnostic and Statistical Manual Version 5 (CAPS-5)

    Semi-structured clinical interview assessing severity of PTSD symptoms administered by a trained, blinded assessor. The range of scores is 0-80. Mpre-Mpost is presented, so positive numbers indicate a reduction in PTSD symptom severity from before to after the intervention.

    Baseline to post-treatment (approx 12 weeks)

Secondary Outcomes (5)

  • Patient Health Questionnaire Depression Items (PHQ-9)

    Baseline to post-treatment (approx 12 weeks)

  • State-Trait Anxiety Inventory, State Subscale

    Baseline to post-treatment (approx 12 weeks)

  • State-Trait Anger Expression Inventory - II (STAXI-II), State Anger Subscale

    Baseline to post-treatment (approx 12 weeks)

  • Insomnia Severity Index

    Baseline to post-treatment (approx 12 weeks)

  • Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference 4a

    Baseline to post-treatment (approx 12 weeks)
