Data Collection Upon the approval of ethics, the researcher will collaborate with the site-PI from the community and volunteers from residents' committee to recruit study participants. Eligibility of participants will be assessed face-to-face by researcher nurse before obtaining informed consent. Data on socio-demographics, past medical history and health conditions will also be collected. Data will be collected at 4 different intervals: baseline (pre-test), 3 months (post-test 1), 6 months (post-test 2) and 12 months (post-test 3) from the baseline. The RA B will arrange appointment with participants to collect the data through face-to-face interview as some older adults might be illiterate and are unable to self-administer the questionnaire.
