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.
