Evaluating the mobile Mantram Repetition Program for veterans with PTSD: A multimethod randomized feasibility trial of self-directed versus text support delivery.

Objective: While mobile delivery can help increase access to evidence-based treatment for veterans with posttraumatic stress disorder (PTSD), feasibility and acceptability are of concern with the potential for high attrition rates and limited participation. The Mantram Repetition Program (MRP), a meditation-focused approach with documented efficacy for reducing symptoms of PTSD and insomnia, was adapted as a brief, mobile-delivered MRP (mMRP) training. This study assessed implementation indicators of mMRP and compared self-directed users of mMRP versus users who received additional text message support.

Method: Thirty-six veterans with clinically significant PTSD symptoms (M_age = 50.50 years; 83.3% male; 72.2% White; 88.9% heterosexual) completed four weekly training video modules. Participants completed questions related to program satisfaction, mantram repetition use, clinical measures, and a 30-min individual interview.

Results: Participants reported using their mantram between 4 and 5 days per week. Participants indicated that mMRP was generally acceptable, appropriate, and feasible across quantitative and qualitative data. On clinical measures, change from pre- to postintervention was significant for the brief symptom screen, PTSD symptoms, and Personal Health Inventory but not for depression or insomnia symptoms. No significant differences were found between the self-directed and supported conditions; however, data suggest that participants primarily engaged with the support for administrative needs. Qualitative data highlighted suggestions for mMRP improvement, including alternative methods for receiving support and more content on how to use the skills taught.

Conclusions: Findings suggest that mMRP can be delivered in a brief format, with veterans learning and using mantram repetition. Developing additional ways of individualizing the mMRP and further testing are warranted. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
