Clinical Trial Summary

The aim of this study is to evaluate the efficacy of gamified competition (delivered through a smartphone) for improving the physical activity and sleep of medical interns.

Description:

Due to their high-stress workloads, medical interns tend to have lower sleep and decreased physical activity. The goal of this study is to evaluate the efficacy of gamified competition (delivered through a smartphone) for improving the physical activity and sleep of medical interns. During the study, they are teamed up by programs and institutions and compete with other teams, which aim to motivate them to have more physical activity and sleep duration during their internship year.

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 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.

Intervention

Behavioral:
• 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Average daily mood score	Through the study mobile app, participants enter a mood score (scale 1-10) every day of the study. 1 corresponds to lowest mood and 10 corresponds to highest mood.	Daily, throughout intern year (1 year)
