Participatory action research was conducted in two municipalities in urban (Bologna, Italy) and rural (Sevilla La Nueva, Spain) settings with older adults and people with disabilities, healthcare professionals, and communication managers. Data collection comprised a survey, interviews, and focus group interviews for developing a physical activity enhancement program, a mobile device application, and a citizen engagement strategy. Evaluation of the program's usability focused on feasibility, appropriateness, acceptability, and quality of life. The enhancement of physical activity in the two community-based settings revealed similarities and differences in the needs of citizens in the two participating municipalities. Similarities were related to behavioral change for enhancing physical activity. Differences in infrastructure were the main factors driving the need for contextual adaptations. Overall, participants were positive about the appropriateness, feasibility, and acceptability of the program.
