Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Change from baseline in participants' weekly physical activity participation at 3 months.

  Quantified as minutes of moderate to vigorous physical activity measured with accelerometry. Participants will wear an accelerometer for a minimum of 10 hours per day for 7 consecutive days. Changes in this measure will be examined (3 months to baseline, 3 months to 6 weeks, 6 weeks to baseline).

  Baseline, 6 weeks, and 3 months

Secondary Outcomes (10)

• Change in Body Mass Index from baseline to 3 months.

  Baseline and 3 months

• Change in waist circumference from baseline to 3 months.

  Baseline, 3 months

• Change in self-reported physical activity from baseline to 3 months.

  Baseline, 6 weeks, 3 months.

• Change in quality of life from baseline to 3 months measured using the Short Form 12 questionnaire.

  Baseline, 6 weeks, 3 months

• Change in life satisfaction from baseline to 3 months measured using Diener's satisfaction with life scale in a questionnaire.

  Baseline, 6 weeks, 3 months

Study Arms (2)

Group 1 - Self monitored

ACTIVE COMPARATOR

Fitbit use and reports details: Participants will receive a Fitbit device to wear for 3 months. They will engage with the Fitbit application on their smartphone or tablet device and receive a Weekly Progress Report from Fitbit.

Behavioral: Fitbit use and reports

Group 2 - Partner monitored

EXPERIMENTAL

Fitbit use and reports details: Participant will receive a Fitbit device to wear for 3 months. They will engage with the Fitbit application on their smartphone or tablet device. Participant will also engage with their partner through the Fitbit application. They will have access to their partner's daily progress and be able to communicate through the application. They will also receive their partner's Weekly Fitbit Reports and have a weekly discussion about the Weekly Fitbit Report.

Behavioral: Fitbit use and reports; Behavioral: Partner engagement

Interventions

Fitbit use and reports BEHAVIORAL

Participants will receive a Fitbit device to be used for the duration of the study. Participants will engage with the Fitbit and application and receive Weekly Progress Reports from Fitbit.

Group 1 - Self monitored; Group 2 - Partner monitored

Partner engagement BEHAVIORAL

Participants will be connected with their partner in the Fitbit app and therefore have the ability to access their partner's progress. Participants' Weekly Progress Reports will be automatically forwarded to their partner. Participants will engage in a weekly discussion on the topic of their Weekly Progress Reports.

Group 2 - Partner monitored
