Trauma Center Trauma-Sensitive Yoga Versus Cognitive Processing Therapy for Women Veterans With PTSD Who Experienced Military Sexual Trauma: A Feasibility Study

BACKGROUND

Posttraumatic stress disorder (PTSD) is a common sequela to military sexual trauma (MST) among women veterans. Yoga has shown promise in research examining its benefit for symptoms and sequela of PTSD.

AIMS

The objective of this study was to evaluate the feasibility of a randomized controlled trial (RCT) of Trauma Center Trauma-Sensitive Yoga (TCTSY) for women veterans with PTSD related to MST.

METHOD

In this feasibility study, the final sample included women veterans (n = 41) with PTSD related to MST accessing health care in a Veterans Affairs Health Care System in the southeast United States; the majority were African American (n = 33; 80.5%). Interventions used established protocols of 10 weekly sessions of group TCTSY versus 12 weekly sessions of group Cognitive Processing Therapy (CPT). PTSD was assessed via clinical interview and participant report. Additional data collection included multiple participant-reported outcomes commonly associated with PTSD and psychophysiological measures. We also collected data regarding participant satisfaction and feasibility-related feedback from participants and providers.

RESULTS

Feasibility and acceptability were evaluated via demand, practicality, fidelity, and acceptability. This was measured by expressed interest, attendance, program completion, barriers to care and satisfaction with treatment, and satisfaction with interventions and data collection.

CONCLUSIONS

Results indicate the RCT design and TCTSY implementation were feasible; a full-scale RCT was subsequently conducted to determine efficacy of the experimental intervention. Recommendations for successful research strategies are provided.

Synchronous Telehealth Yoga and Cognitive Processing Group Therapies for Women Veterans with Posttraumatic Stress Disorder: A Multisite Randomized Controlled Trial Adapted for COVID-19

Background: Providing care over telehealth grew slowly until the COVID-19 pandemic. Since the onset of the COVID-19 pandemic, providing mental health care was readily adapted to virtual means; however, clinical trial research is nascent in adapting methods and procedures to the virtual world. Methods: We present protocol modifications to pivot a multisite randomized controlled trial study, conducted at Southeastern and Pacific Northwestern Veterans Affairs Health Care Systems, from being conducted in-person to virtually, following the onset of the COVID-19 pandemic. We measured outcomes of posttraumatic stress disorder (PTSD) symptoms and psychophysiological markers of stress among female Veterans with PTSD secondary to military sexual trauma. We collected qualitative data about provider and participant experiences with telehealth. Results: Across sites, 200 participants were consented (48 virtually), 132 were randomized (28 to virtual groups), and 117 completed data collection and treatment (69 completed all or some data collection or treatment virtually). Conclusions: The pivots made for this study were in response to the COVID-19 pandemic and offer innovative procedures leveraging technology and contributing to the broader landscape of conducting research virtually. Clinical Trials Number: NCT02640690.

Determining Psychoneuroimmunologic Markers of Yoga as an Intervention for Persons Diagnosed With PTSD: A Systematic Review

There is a growing body of research on yoga as a therapeutic intervention for psychological symptoms of post-traumatic stress disorder (PTSD) accompanied by speculations on underlying physiologic mechanisms. The purpose of this systematic review is to identify, qualitatively evaluate, and synthesize studies of yoga as an intervention for PTSD that measured physiologic outcomes in order to gain insights into potential mechanisms. The focus is on studies evaluating yoga as a therapeutic intervention for PTSD rather than for trauma exposure, PTSD prevention, or subclinical PTSD. Multiple databases were searched for publications from the past two decades using terms derived from the question, "In people with PTSD, what is the effect of yoga on objective outcomes?" Eligibility criteria included yoga-only modalities tested as an intervention for formally diagnosed PTSD with at least one physiologic outcome. Results of this review confirmed that, though much of the published literature proposes physiological mechanisms underlying yoga's effects on PTSD, very few studies ( n = 3) have actually evaluated physiological evidence. Additionally, several studies had methodological limitations. In light of the limited data supporting yoga's beneficial effects on autonomic nervous system dysregulation, we present a theoretical model of the psychoneuroimmunologic processes associated with PTSD and the effects yoga may have on these processes to guide future research. Gaps in the literature remain for mechanisms related to activation of the hypothalamic-pituitary-adrenal axis and inflammation. Additional rigorous mechanistic studies are needed to guide development of effective yoga interventions for PTSD to augment existing evidence-based PTSD treatments.
