Group singing improves depression and life quality in patients with stable COPD: a randomized community-based trial in China

Abstract

Purpose

To explore the effects of group singing therapy on depression symptoms and quality of life of patients with stable chronic obstructive pulmonary disease (COPD).

Methods

Patients with COPD were randomly allocated to intervention ( n = 30) and control groups ( n = 30). The intervention group received group singing therapy once a week for 24 sessions along with routine health education, whereas the control group only received the routine health education. All patients were administered the Hospital Anxiety and Depression Scale depression subscale (HADS-D) and the Clinical COPD Questionnaire (CCQ). Data were collected at baseline and at 1, 3, and 6 months.

Results

Fifty-six participants completed this trial. Significant between-group differences were observed with respect to the main effect of group and time as well as the effect of group × time interaction on HADS-D score. The HADS-D score was significantly improved 1, 3, 6 months after group singing therapy. The CCQ total scores were significantly different between the two groups with respect to the main effect of group and time and the group × time interaction effect. Significantly better CCQ was detected in the intervention group at 3 months and 6 months after intervention.

Conclusions

Group singing therapy reduces depressive symptoms and improves the quality of life of patients with stable COPD.
