Brief 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.

Detailed 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.

• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Competition group

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 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.

Group Type: EXPERIMENTAL

Intern Health Study competition-related mobile notification

Intervention Type: BEHAVIORAL

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

Intervention Type: BEHAVIORAL

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

Intervention Type: BEHAVIORAL

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.

Group Type: EXPERIMENTAL

Intern Health Study mobile app

Intervention Type: BEHAVIORAL
