Peer-supported mindfulness-based intervention for managing depressive symptoms in community-dwelling older adults: Protocol for a randomized controlled trial

Abstract

Background: Depression in old age is a public health concern contributing to individual and societal burdens. Mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) have shown promise in reducing depressive symptoms. However, time commitments associated with these interventions could pose challenges to older adults. To address this, we propose a briefer mindfulness-based intervention (MBI) with peer supporters to engage and support participants experiencing time constraints and distress. This protocol describes a study examining the efficacy of a peer-supported MBI in reducing depressive symptoms among older adults. Methods: The study involves a two-arm randomized controlled trial and a propensity score-matched comparison group. Participants will receive either (1) a social worker-led MBI consisting of six weekly 2-h sessions or (2) the same MBI supplemented with peer supporters. A total of 138 community-dwelling older adults above 60 years old, with mild to moderately severe depressive symptoms, will be recruited through local non-governmental organizations. Study metrics will be assessed at baseline, completion of the intervention, and 3 months following the intervention, through self-assessed questionnaires. The primary outcome is depressive symptoms measured by PHQ-9. Data (n = 69) from a prior study involving mindfulness teacher-led MBCT with the same participant criteria and data collection procedures will be matched to the other two groups using propensity scores. Discussion: The study results will suggest the efficacy and scalability of a peer-supported MBI in community mental health services, improving intervention accessibility and the mental health of older adults.
