Study Description

This study includes a 12-week active intervention period. Interested participants will complete a study orientation webinar, then continue to a baseline visit and online questionnaires if interested. They will then complete 7-days of accelerometry monitoring to measure current physical activity levels. If eligible, they will attend a brief kick-off meeting to receive their Fitbits and study apps. The intervention period is 12 weeks, all remotely delivered. The intervention focuses on families working to increase their moderate- to-vigorous intensity physical activity. At 12 weeks, families will attend a brief in-person assessment visit and complete online questionnaires and 7 days of accelerometry, and complete a semi-structured interview via Zoom to discuss their experiences and provide feedback for future program modifications.
