Monitoring Physical Activity (Fitbit)

The purpose of this study is to examine the effect of monitoring and sharing physical activity outcomes (using Fitbit technology) with a domestic partner on physical activity participation. Primary research question: Does sharing physical activity outcomes from wearable technology with a participant\'s partner improve overall physical activity over 3 months compared to not sharing outcomes? Physical activity will be measured as minutes of moderate to vigorous physical activity per week. Hypothesis: Knowledge that physical activity outcomes are visible to a participant\'s partner will serve as a proxy-supervision intervention. Awareness of partner\'s progress will serve as further motivation. Both factors will improve physical activity adherence in comparison to participants without shared outcomes.
