A Personalized Health Behavior System

The objectives of this study are to examine the usability and efficacy, for diverse older adults, of a new tablet-based dynamic system: the Fittle Senior System (FSS) that will provide: (1) personalized behavior-change programs for improved diet and increased physical activity and (2) online social interaction and support from small teams pursuing similar goals. The proposed study involves a two group randomized trial where participants will be randomized to the Fittle Senior System or to a paper-based psycho-educational control condition following a baseline assessment. The duration of the intervention phase will involve an active 12-week intervention phase followed by a 12-week maintenance phase. We will recruit and randomize 180 community dwelling adults aged 65+ years, who live alone and are at risk for social isolation. Participants will be assessed at baseline, 3 months post active intervention and 3 months post maintenance (6 months following active intervention) on measures of health and health behaviors, and indices of social support.
