Trauma-Sensitive Yoga for Post-Traumatic Stress Disorder in Women Veterans who Experienced Military Sexual Trauma: Interim Results from a Randomized Controlled Trial

Abstract: The objective of the study is to conduct an interim analysis of data collected from an ongoing multisite randomized controlled trial (RCT) assessing the effectiveness of Trauma Center Trauma-Sensitive Yoga (TCTSY) for post-traumatic stress disorder (PTSD) among women veterans with PTSD related to military sexual trauma (MST). The purpose of the interim analysis was to assess outcomes from the primary site, which is geographically, demographically, culturally, and procedurally distinct from the second site. RCT was conducted within a Veterans Administration Health Care System. Data collection included preintervention through 3 months postintervention. Enrollment for the main site was 152 women. The sample size for the intent-to-treat analysis was 104. The majority were African American (91.3%) with a mean age of 48.46 years. The TCTSY intervention (n = 58) was conducted by TCTSY-certified yoga facilitators and consisted of 10 weekly 60-min group sessions. The control intervention, cognitive processing therapy (CPT; n = 46), consisted of 12 90-min weekly group sessions conducted per Veterans Administration protocol by clinicians in the PTSD Clinic. The Clinician Administered PTSD Scale for DSM-5 (CAPS-5) was used to assess current PTSD diagnosis and symptom severity, including overall PTSD and four symptom clusters. The PTSD checklist for DSM-5 (PCL-5) was used to obtain self-report of PTSD symptom severity, including total score and four symptom clusters. The findings reported here are interim results from one clinical site. For both the CAPS-5 and PCL-5, total scores and all four criterion scores decreased significantly (p < 0.01) over time in all five multilevel linear models within both TCTSY and CPT groups, without significant differences between groups. There were clinically meaningful improvements seen for both TCTSY and CPT with 51.1%–64.3% of TCTSY subjects and 43.5%–73.7% of CPT decreasing their CAPS-5 scores by 10 points or more. Effect sizes for total symptom severity were large for TCTSY (Cohen's d = 1.10–1.18) and CPT (Cohen's d = 0.90–1.40). Intervention completion was higher in TCTSY (60.3%) than in CPT (34.8%). Symptom improvement occurred earlier for TCTSY (midintervention) than for CPT (2 weeks postintervention). The results of this study demonstrate that TCTSY may be an effective treatment for PTSD that yields symptom improvement more quickly, has higher retention than CPT, and has a sustained effect. TCTSY may be an effective alternative to trauma-focused therapy for women veterans with PTSD related to MST.

    Qualitative analysis of the lived experience of reproductive and pediatric health care in the military health care system

    Abstract: Introduction: Persistent inequities exist in obstetric and neonatal outcomes in military families despite universal health care coverage. Though the exact underlying cause has not been identified, social determinants of health may uniquely impact military families. The purpose of this study was to qualitatively investigate the potential impact of social determinants of health and the lived experiences of military individuals seeking maternity care in the Military Health System. Materials and methods: This was an Institutional Review Board-approved protocol. Nine providers conducted 31 semi-structured interviews with individuals who delivered within the last 5 years in the direct or purchased care market. Participants were recruited through social media blasts and clinic flyers with both maximum variation and homogenous sampling to ensure participation of diverse individuals. Data were coded and themes were identified using inductive qualitative research methods. Results: Three main themes were identified: Requirements of Military Life (with subthemes of pregnancy notification and privacy during care, role of pregnancy instructions and policies, and role of command support), Sociocultural Aspects of the Military Experience (with subthemes of pregnancy as a burden on colleagues and a career detractor, postpartum adjustment, balancing personal and professional requirements, pregnancy timing and parenting challenges, and importance of friendship and camaraderie in pregnancy), and Navigating the Healthcare Experience (including subthemes of transfer between military and civilian care and TRICARE challenges, perception of military care as inferior to civilian, and remote duty stations and international care). Conclusions: The unique stressors of military life act synergistically with the existing health care challenges, presenting opportunities for improvements in care. Such opportunities may include increased consistency of policies across services and commands. Increased access to group prenatal care and support groups, and increased assistance with navigating the health care system to improve care transitions were frequently requested changes by participants.
