Summary

The aim of this trial is to evaluate the efficacy of an intervention (delivered through a smartphone) for improving the mood, physical activity, and sleep of medical interns.

Detailed description

Due to their high stress workloads, medical interns suffer from depression at higher rates than the general population. Interns also tend to have lower sleep and decreased physical activity. The goal of this trial is to evaluate the efficacy of a mobile health intervention intending to help improve the mental health of medical interns. The intervention sends mobile phone notifications which aim to help interns improve their mood, maintain physical activity, and obtain adequate sleep during their internship year. The primary aim of the study is to evaluate how notifications affect participants' weekly mood, as measured through a daily one question mood survey. The second primary aim of the study is to evaluate how notifications affect participants' long-term mental health, as measured by the Patient Health Questionnaire. The first secondary aim is to evaluate how mood notifications affect participants' weekly mood. The second secondary aim is to evaluate how activity notifications affect participants' weekly step count. The third secondary aim is to evaluate how sleep notifications affect participants' weekly sleep duration. In order to better optimize notification delivery, the final aim (exploratory) is to understand moderators of these effects. Moderators of interest are previous week's mood, previous week's step count, previous week's sleep duration, study week, sex, previous history of depression, and baseline neuroticism.
