Brief Summary

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

In this study, we are evaluating the effectiveness of a yoga intervention to treat posttraumatic stress disorder (PTSD), its associated symptoms of chronic pain and insomnia, and biological and physiological responses to trauma and PTSD in women Veterans who experienced military sexual trauma (MST). If effective, this yoga intervention could reduce PTSD symptoms and chronic pain, improve sleep quality, and decrease the body's automatic "fight or flight" stress response and the damage this stress response causes in the body, including heart disease and diabetes. This intervention could improve these women Veterans' quality of life and social functioning, for example, going to work and having satisfying relationships with family and friends. This study may support an innovative, complementary and alternative PTSD treatment for women Veterans who experienced MST. This new, evidence-based PTSD treatment could supplement current PTSD treatments. Clinical guidelines for this yoga intervention could be implemented nationally in the VA health care system.

Detailed Description

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

Objectives: The overall goal of this project is to maximize the health, social functioning, and quality of life of women Veterans with posttraumatic stress disorder (PTSD) who have experienced military sexual trauma (MST). The specific aims of this randomized controlled trial (RCT) are to evaluate the effectiveness of a trauma-sensitive yoga intervention designed specifically for women who experienced sexual trauma as compared to a gold-standard PTSD treatment, Cognitive Processing Therapy, to 1) treat PTSD and its co-morbid symptoms of chronic pain and insomnia, 2) improve social functioning and quality of life, and 3) reduce the biological and psychophysiologic responses associated with PTSD in women Veterans who experienced MST.

Research Plan: This five year RCT is the next step following the NRI Pilot Study (NRI 12-417) in which the investigators demonstrated the feasibility of recruitment, retention, randomization, intervention implementation, and data collection, including biological and psychophysiological data. Women Veterans seeking treatment for PTSD were recruited from a primary site (southeast US) and second site (northwest US) and were randomized to Trauma Center Trauma-Sensitive Yoga (TCTSY) (10 weekly sessions) or Cognitive Processing Therapy (CPT) (12 weekly sessions); both intervention protocols are data-driven. The target enrollment sample size is 210, with a target final sample of 100 or more. The investigators are conservatively allowing for 50%-60% retention, based on pilot study results.

Methods: Data Collection: Data are collected at four points, baseline through 3-months post-intervention. Outcome measures include self-report, clinical assessments and biologic and psychophysiologic markers. Specific outcomes include PTSD symptom severity, chronic pain, insomnia, social functioning, quality of life, cytokines (IL-6, IL-10), C-reactive protein, heart rate variability, and dark-enhanced startle. Data Analysis: Comparisons between the groups at baseline will be run using t-tests, Mann Whitney non-parametric tests, and chi-square tests as appropriate. Multilevel mixed models (MLM) will be used to analyze the differences between the groups over time. MLM adjusts for attrition (missing data) over time and applies appropriate correlation structure between the time points.

Clinical Relevance: Women Veterans experience MST and PTSD at alarming rates; consistently reported prevalence rates for both among VHA patient samples are 20% or more. MST and PTSD put this population at risk for significant physical and mental health symptoms, including chronic pain, suicide, and negative health behaviors. This RCT may provide sufficient evidence to support an innovative, complementary and alternative PTSD treatment for women Veterans who experienced MST. The positive effects of reducing distressing symptoms and PTSD-related psychophysiological stress would likely improve social functioning and quality of life and minimize the significant medical consequences of PTSD in this population. This new, evidence-based PTSD treatment could supplement existing evidence-based PTSD treatment modalities. Clinical guidelines for this innovative intervention based on evidence from this clinical trial could be disseminated to and implemented in VA Medical Centers nationwide.
