Outcome Measures
Primary Outcomes (1)
Average daily step count
Participants' daily step counts are recorded through a Fitbit or an apple watch. High step counts are considered a positive outcome as it indicates more physical activity. For teams randomized into competition arm and randomized to compete on step count, their average daily step count is compared with the average step count of the opponent team.
Daily, throughout intern year (1 year)
Secondary Outcomes (1)
Average daily mood score
Daily, throughout intern year (1 year)
Study Arms (2)
Competition group
EXPERIMENTALPrograms with at least five interns were grouped into program-based teams. Interns within the same residency institution in programs that did not meet this criterion were grouped into institution-based teams, with a minimum of five participants per team. For each week, an eligible team is randomized to either a steps competition or non-competition group with 50/50 chance. For those randomized to competition arm, teams were assigned an opponent team by total randomization, by which the opponent team was assigned regardless of institution and specialty.
Non-competition group
EXPERIMENTALFor each week, an eligible team is randomized to either competition or non-competition group with 50/50 chance.
Interventions
Participants will receive three types of push notifications: 1. Alert of competition type (steps or sleep) and opponent (Sunday 9pm), 2. Competition score status update (Wednesday 9pm, Saturday 11am), and 3. Competition final results (Monday 12pm).
The Intern Health Study mobile app is able to conduct a daily mood survey. It also aggregates and visualizes historical data on intern mood, activity, and sleep.
Participant can view their current competition scoreboard and competition history at any time via the study app.
