Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary aim of this study is to investigate whether introducing competition mechanisms into mobile health (mHealth) interventions can improve a medical intern's activity-related behavioral outcomes: daily step counts and sleep duration. The first secondary aim is to assess the time-varying competition effect on their behavioral outcomes. The second secondary aim is to evaluate how social cooperation (competing within the same institution or program) moderates the effect of competition on behavioral outcomes. The first exploratory aim is to assess the competition effect on study engagement and the second exploratory aim is to evaluate the competition effect on mental outcome, mood score.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Competition arm
Programs 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 competition or non-competition group with 50/50 chance. For those randomized to competition arm, teams were assigned an opponent team according to a weekly equally randomly selected rule from three options: 1. total randomization, by which the opponent team was assigned regardless of institution and specialty; 2. within-institution randomization, by which two competing teams were from the same institution; 3. within-specialty randomization, by which two paired teams were from the same specialty. For each pair of competing teams, there was a 50/50 chance that they would compete on average daily step counts or average daily sleep minutes.
Intern Health Study competition-related mobile notification
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).
Intern Health Study mobile app
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.
Intern Health Study mobile app competition scoreboard and history
Participant can view their current competition scoreboard and competition history at any time via the study app.
Non-competition group
For each week, an eligible team is randomized to either competition or non-competition group with 50/50 chance.
Intern Health Study mobile app
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.
