Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Within-participant micro-randomization
Each day in the study, with probability .5 for each, a participant is randomized to receive a notification that day or no notification that day.
If a participant is assigned to receive a notification that day, 1 message set will be randomly selected from a pool of 358 core message sets. Each core message set will be comprised of 4 messages containing comparable content, however they will be tailored based on the participant's wearable (steps, sleep) or mood data for the specified time interval (7 days, 30 days, since the start of internship) as follows: 1) no data, 2) low, 3) moderate, or 4) high.
Intern Health Study behavioral change mobile notification
The study's mobile app will be used to deliver push notifications. The notifications appear on the participant's phone lock screen. The notifications include 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. All notifications are categorized as one of five therapeutic approaches: 1) CBT-Behavioral, 2) CBT-Cognitive, 3) Distanced Self-Talk, 4) Mindfulness, 5) Motivational Interviewing.
