Study design
BLIND
An open-label randomized controlled trial was conducted in a nursing home in Wuhan China. This study was approved by the Wuhan University Institutional Review Board. The study was registered with the Chinese Clinical Trial Registry in 14/01/2022 (registration number: ChiCTR2200055614). All participants provided written informed consent. The data was collected by two nursing students who were trained to be familiar with the measurement procedures and the criteria for eligibility of the questionnaires. The receptive music therapy was conducted by a trained music therapist and an undergraduate nursing student who had studied nursing courses for older adults and music therapy. Since it was difficult to blind the participants in the intervention, only the outcome assessors were blinded to avoid the bias caused by subjective factors. This study was conducted following the CONSORT guidelines.
