Music training improves depressed mood symptoms in elderly people: a randomized controlled trial

The effectiveness of music training on depressed mood and general cognitive function in elderly participants is verified in this study. Music activities consisted of improvisation exercises for stimulating interpersonal skills, mood, and cognitive functions. A mixed research method was adopted, including standardized measures (Mini-Mental State Examination and Geriatric Depression Scale) and follow-up semistructured interviews. The research design included pre- and postevaluation with randomized experimental and control groups. Participants were 45 care residents aged 62 to 95, healthy and with cognitive impairment. Results revealed a significant improvement in depression index (Geriatric Depression Scale) for the experimental period (t = 1.450; p < .005; d = 0.453) while the control group had no improvement (t = 0.080; p > .1; d = 0.025). In addition, a significant improvement was found in the cognitive level (Mini-Mental State Examination) for the experimental (t = 2.300; p < .005; d = 0.668) than the control group that had a significant reduction (t = 1.240; p < .05; d = 0.273). This study provides evidence that music training has a positive impact on depressed mood and general cognitive function in elderly participants. These types of music training sessions could provide aid to control the symptoms of depression, delay the deterioration of cognitive function, and enhance social–cognitive function, especially in individuals presenting with cognitive impairment.
