What drives older adults' use of mobile registration apps in Taiwan? An investigation using the extended UTAUT model.

This study aimed to provide an integrated model that examines the determinants of older adults' intention to use mobile registration applications (apps) based on UTAUT, and the role of aging factors including perceived physical condition, technology anxiety, inertia, and self-actualization needs. The proposed model was tested by PLS (Partial Least Squares) with data collected from 361 older adults. Results indicated that three variables derived from UTAUT, namely performance expectancy, social influence, and facilitating conditions, influence mobile registration app usage intention.
