Ethics and dissemination
This study has been approved by the Research Ethics Committee of Tung Wah College, Hong Kong (reference number: REC2023158).In case there are changes in the protocol, the research team will notify the sponsor, funder, and Research Ethics Committee. Then, the research venues (i.e., centers for older people) will be informed and a copy of the revised protocol will be sent to them. If there are any deviations from the protocol, the changes will be fully documented using a breach report form and the details in the clinical trial registry will also be updated.All participants will be asked to give their written informed consent to participate in the proposed study. The written consent will be obtained by a research assistant after explaining the study to the participants guided by a standardized information sheet. No identifying images or other personal or clinical details of participants are presented here or will be presented in reports of the trial results.Details of the protocol, participant-level data, statistical code, the written consent form, and the information sheet about the study to be provided to participants are available from the corresponding author upon request. After the completion of the study, only the research team members have the right to access the final full dataset. Given that there are no anticipated serious harms, there are no provisions for ancillary and post-trial care for compensation to those who suffer harm from trial participation.The findings will be disseminated in peer-reviewed journals, presented at international and local conferences with related themes (e.g., mental health, gerontology, therapeutic virtual reality, and LTCF), and shared in local media (e.g., e-newspaper).
