A randomized controlled trial of two simple mind-body programs, Kirtan Kriya meditation and music listening, for adults with subjective cognitive decline: Feasibility and acceptability

Abstract

Purpose of the studyIn this randomized controlled trial (RCT), we assessed the feasibility and acceptability of two simple home-based relaxation programs in adults experiencing subjective cognitive decline, a strong predictor of Alzheimer's disease. Design and methodsSixty participants were randomized to a beginner Kirtan Kriya meditation (KK) program or a music listening (ML) program. Participants were asked to practice 12min daily for the first 12 weeks, then as often as they liked for the following 3 months. Participants underwent assessments at baseline, 12 weeks, and 6 months to evaluate changes in key outcomes. Feasibility and acceptability were evaluated by measuring recruitment and retention rates, assessment visit attendance, practice adherence, and treatment expectancy; exit questionnaires completed at 12 weeks and 6 months provided additional data regarding participant experience with the study, perceived barriers to and facilitators of practice, reasons for drop-out, and views regarding the assigned intervention. ResultsFifty-three participants (88%) completed the 6 month study. Adherence in both groups was excellent, with participants completing 93% (91% KK, 94% ML) of sessions on average in the first 12 weeks, and 71% (68% KK, 74% ML) during the 3 month, practice-optional, follow-up period. At week 12, over 80% of participants indicated they were likely to continue practicing following study completion. Responses to both structured and open-ended exit questionnaire items also suggested high satisfaction with both programs. ConclusionsFindings of this RCT of a beginner meditation practice and a simple ML program suggest that both programs were well accepted and the practices are feasible in adults with early memory loss.
