Needs assessment in community-dwelling older adults toward digital interventions to promote physical activity: Cross-sectional survey study.

Community-dwelling older adults may be willing to use DIs to promote PA in the long term, but this study identified particular needs and requirements in terms of design, technological realization, delivery mode, support, and individualization/personalization among the sample. Our results can inform future developments of DIs to promote PA specifically tailored to older adults. However, caution is warranted in interpreting the findings due to the sample's high PA and education levels.
