Trial Summary

What is the purpose of this trial?

The purpose of this study is to determine the efficacy of a new digital health tool that uses a phone and smartwatch to encourage physical activity and increase weekly amounts of Moderate to Vigorous Physical Activity (MVPA) over 12 months among adults compared to a digital health intervention that mimics a standard of care corporate wellness program.

Treatment Details

Interventions

COT-Based Intervention (Behavioral Intervention)

Trial OverviewThe study tests a new mobile health tool that pairs with your phone and watch to boost physical activity over the course of a year. It will be compared against standard digital wellness programs to see if it helps people do more moderate-to-vigorous exercise.

Experimental Treatment

Active Control

Group I: COT-Based InterventionExperimental Treatment1 Intervention

The COT-based intervention will include the following to improve both steps/day (move more), and improving minutes/week of MVPA (exercise): adaptive daily steps/day goal-setting plus feedback; positive reinforcement (i.e., points, which translate to gift cards), self-monitoring of both steps/day and min/week MVPA; education about MVPA sent via text message in both conditions; planning support for scheduling bouts of MVPA via SMS in both conditions; and motivational messages sent via SMS in both conditions, and the use of a self-experimentation tool (REFLECT), developed based on prior successful pilot efforts, focused on fostering effective self-regulatory capacities of individuals.

Group II: ControlActive Control1 Intervention

The non-COT approach was designed to be an equivalent to emerging standard of care options for digital health worksite wellness programs to increase PA (control) for a 12-month study period. Participants assigned to the non-COT-based (control) group will receive the latest Fitbit Versa smartwatch and will download the Fitbit smartphone app. Unlike the intervention group, the daily step goal and the accompanying number of points will be static (10,000 steps/day; 150 points/day, respectively). The goal will be delivered to participants via the standard Fitbit app features and points will be communicated via email. Participants will also receive a weekly PA goal (150 minutes of MVPA/per week) and the same accompanying motivational and informative texts that the intervention group receives. Control participants will not complete the physical activity and exercise reflection and planning exercise (Reflect).
