Study Details
Timeline
Interventions
The study's mobile app will be used to deliver intervention notifications. The intervention notifications appear on the participant's phone lock screen. The notifications have 3 categories: mood notifications, activity notifications, sleep notifications. Mood notifications aim to increase the participant's mood. Activity notifications aim to increase the participant's physical activity. Sleep notifications aim to increase the participant's sleep duration. To increase the category of interest, the notifications use two types of messages: life insights and tips. Life insights provide participants information on their historical data (for a given category) in order to help them self-monitor. Tips are non-data based notifications which provide general advice for improving the category of interest.
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.
