Research and Development of a Social Cognitive Theory-based Mobile Application to Enhance Physical Activity in Aging...

This study addressed the unique challenges of promoting physical activity among older adults with chronic diseases in the informal workforce, who often face physical limitations and lack structured schedules or access to workplace wellness programs. To address this gap, a mobile application based on Social Cognitive Theory was developed to encourage physical activity among older adults with hypertension. Guided by the ADDIE model, the app's development included a needs assessment involving a survey of 90 individuals and a literature review. This informed the design of key features, such as educational content, a physical activity calendar, exercise location identification, a ranking and rewards system, and a discussion forum. Rigorous testing was conducted, including pilot testing (n=6), usability testing (n=90), and content validation by experts (n=5). The app was well-received by older adults with hypertension (n=90, mean age=66.7 y, 82% female), who particularly valued features promoting self-care and information on the benefits of physical activity. This theoretically driven app offers a promising solution to promote physical activity in this vulnerable population. Further research will evaluate its effectiveness and explore its wider applicability.
