Evaluation of MBCT Implemented in Vietnamese Buddhist Pagoda

Background

Depression presents a substantial public health burden around the world. Evidence-based psychotherapy treatments (psychotherapy EBT) for depression exist but access is often limited, particularly in low- and middle-income countries (LMIC), by mental health stigma and scarcity of professional mental health providers. One approach to address these issues is mental health task-shifting, transferring mental health services from highly trained mental health professionals operating in formal mental health settings, to non-mental health professionals or lay people receiving focused training in a particular mental health program, operating in non-mental health settings (e.g., schools; religious settings). Purposes of the present study are to (a) adapt Mindfulness-Based Cognitive Therapy (MBCT) for depression - a psychotherapy depression EBT - for implementation in Vietnamese Buddhist pagoda in VN (MBCT-VN); and (b) conduct a cluster-randomized clinical trial of MBCT-VN, implemented in Vietnamese Buddhist pagoda. Vietnamese Buddhist pagoda are selected as the task-shifting site because they represent a potentially low stigma, culturally-congruent site for task-shifting implementation of mindfulness-based mental health treatments.

Methods

MBCT was adapted for the present project through a collaborative team process, producing the MBCT-VN program. The clinical trial evaluation will involve a cluster-randomized comparison between (a) the treatment condition MBCT-VN, and (b) a treatment-as-usual control condition, Buddhist meditation as implemented in pagoda. To reduce cross-group contamination, pagoda will be the unit of assignment. Outcome assessments will include four timepoints across four months. One hundred and sixty adult participants will be recruited from eight (four treatment; four control) Buddhist pagoda in the Hanoi, Vietnam area. The primary outcome will be level of depression (Patient Health Questionnaire-9: PHQ-9); the secondary outcome will be quality of life (Quality of Life Enjoyment and Satisfaction Questionnaire: Q-LES-Q). The study will assess and evaluate several Implementation Science factors (e.g., Treatment Acceptability) as well as other potential moderators of treatment effects, and potential mediators such as increase in depression mental health literacy and decrease in depression stigma. Inferential analyses will use a general linear mixed model framework with a latent growth curve framework, with propensity covariates.
