Study Overview
Brief Summary
This paper describes the rationale and design of a Phase 3 RCT comparing Transcendental Meditation to Present Centered Therapy for posttraumatic stress disorder (PTSD), suicidal ideation, alcohol use, and depressive symptoms in Veterans. In this multisite trial, 450 Veterans meeting Diagnostic and Statistical Manual-5 (DSM-5) criteria for PTSD will be recruited from nine VA and academic medical center sites across the U.S. Study outcomes include changes in PTSD diagnosis and symptom severity (primary), suicidal ideation, alcohol use, and depressive symptoms. Participation includes baseline testing and post-treatment assessments at 12, 24, and 36-weeks. During each assessment visit, Veterans will complete diagnostic interviews, including the Clinician-Administered PTSD Scale for DSM-5 and the Alcohol Timeline Followback, as well as validated self-report measures. Cost-effectiveness of the treatments will be measured using intervention and healthcare costs, the proportion with PTSD diagnosis removed, and Quality-Adjusted Life Years. Finally, single-site substudies will examine pre-to-post-treatment changes in PTSD biomarkers and on magnetic resonance imaging (MRI).
Detailed Description
Background: The evidence supporting the Transcendental Meditation (TM) technique as a treatment for posttraumatic stress disorder (PTSD) has advanced considerably in the past decade. With a recent randomized controlled trial (RCT) suggesting statistical superiority to active control treatments for PTSD (e.g., Present Centered Therapy [PCT]) and noninferiority to first-line PTSD psychotherapies, additional research evaluating the benefits and cost-effectiveness of TM for PTSD among Veterans is needed.
Methods and design: This paper describes the rationale and design of a Phase 3 RCT comparing TM to PCT for PTSD in Veterans. In this multisite trial, 450 Veterans meeting DSM-5 criteria for PTSD will be recruited from nine VA and academic medical center sites across the U.S. Study outcomes include changes in PTSD diagnosis and symptom severity (primary), suicidal ideation, alcohol use, and depressive symptoms. Participation includes baseline testing and post-treatment assessments at 12, 24, and 36-weeks. During each assessment visit, Veterans will complete diagnostic interviews, including the Clinician-Administered PTSD Scale for DSM-5 and the Alcohol Timeline Followback, as well as validated self-report measures. Cost-effectiveness of the treatments will be measured using intervention and healthcare costs, the proportion with PTSD diagnosis removed, and Quality-Adjusted Life Years. Finally, single-site substudies will examine pre-to-post-treatment changes in PTSD biomarkers and on magnetic resonance imaging (MRI).
Discussion: Despite progress in PTSD treatments, new evidence-based treatments are still needed for Veterans who drop-out of or respond poorly to existing trauma-focused psychotherapies and that may assist Veterans with common PTSD-comorbidities such as depression, suicidal ideation, and substance use. This multisite trial seeks to advance the science and potential application of TM as a treatment for PTSD in Veterans.
