Interventions
A detailed description of the intervention program has previously been published [The mHealth app was designed using senior-friendly features such as a consistent and clear visual layout, a large touch point size, minimized sublevels for navigation, and subtitles in the videos and audio contents. Before launching, the app was tested by 10 older adults eligible to join the study, but who were not participants. They were generally satisfied with the features and the senior-friendly design of the app, only indicating that the size of the text, graphics, and buttons needed to be increased.
