The effect of laughter yoga and music intervention on depression, anxiety, and stress in the Rafsanjan-Iran aged: a randomized clinical trial study.

Abstract

This study aimed to compare the effects of laughter yoga and music intervention on depression, anxiety, and stress in aged individuals referred to Rafsanjan health centers. In this 3-arm randomized clinical trial, 91 depressed aged participants aged 60-75 years, referred to Rafsanjan health centers, were randomly assigned to intervention and control groups. The study followed a parallel group design with an allocation ratio of 1:1. The laughter yoga intervention was conducted twice a week for eight weeks, and music intervention consisted of 30-min sessions twice a week for eight weeks. The control group received no intervention ('No treatment' concurrent control). Assessments for depressive symptoms (primary outcome), anxiety, and stress were conducted at baseline, post-intervention, and one month after the intervention. A total of 84 patients were analyzed in three groups included the laughter yoga intervention (n = 31), music intervention (n = 25), or control group (n = 28). Repeated measures ANOVA revealed a significant decrease in depressive and anxiety symptoms (p < 0.001) from pre-test to post-test and one-month follow-ups. The greatest impact of the intervention programs on stress was observed immediately after the intervention, but stress increased one month after the intervention programs (p = 0.125). Both laughter yoga and music interventions proved effective in improving depression, anxiety, and stress in aged individuals. However, laughter yoga intervention demonstrated a superior effect and better acceptance among elders.
