Arm Intervention/treatment
Experimental: HeartSteps Intervention
For activity suggestions, at each available decision time, each participant is randomly assigned to either receive an activity suggestion or not.
Behavioral: HeartSteps: A just-in-time intervention for increasing physical activity among sedentary adults.
HeartSteps is a smartphone based mHealth intervention that contains the following intervention components: (1) contextually-tailored suggestions for activity; (2) motivational messages aimed at keeping individuals motivated to be active; (3) planning of the next week's activity; and (4) adaptive weekly activity goals. Activity suggestions provide individuals with suggestions for how they can be active, and are tailored based on time of day, user's location, day of the week (weekend/weekday), and weather. Motivational messages are delivered to individuals via a push notification. Activity planning asks users to create a plan of how they will be active in the coming week. Participants are prompted to plan once a week. Each week, as part of the weekly planning, HeartSteps suggests an activity goal for the coming week based on their activity levels the previous week. Participants can edit the suggested goal, and the system-suggested goals top out at 150 minutes of activity per week.

Primary Outcome Measures :
  1. 30 minute step count [ Time Frame: 30 minutes ]
    step count within the 30-minute window after each available decision point when activity suggestions are randomized. Assessed using the Fitbit Versa Activity tracker.

  2. Daily step count [ Time Frame: 24 hours ]
    Daily step count on the day of treatment. Assessed using the Fitbit Versa activity tracker.

Secondary Outcome Measures :
  1. MVPA [ Time Frame: 24 hours ]
    Number of minutes of moderate or vigorous physical activity

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description: A de-identified dataset (i.e., containing no raw location/GPS information) will be generated and made available to the research community. The dataset will be stripped of all codes or any other information that could be linked back to the original data or to an individual participant. Prospective users of this dataset must agree to a confidentiality agreement, meaning that they must get permission from the HeartSteps Primary Investigator to share the data with anyone else. All external requests for data will be directed to Dr. Predrag Klasnja. Prospective investigators will submit a written proposal to the HeartSteps Investigator Team outlining the question they will investigate, the specific variables that they need to answer that question, their analytic plan for answering that question, and documentation of sufficient Institutional Review Board oversight (e.g., approval or exemption). Investigators will also need to sign a confidentiality agreement.
