Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this project is to establish the evidence base for equitable accessibility and implementation of the precision sleep medicine mobile application, SHIFT.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SHIFT App

Participants in this condition will receive an access code to download the mobile application and conduct an orientation to SHIFT and the study procedures with a study team member. They will then enter four weeks of study directed use of SHIFT where they are trained on a daily procedure of opening SHIFT at the beginning of their day and planning their day in accordance with the app recommendations. App usage (4 times per week) will be incentivized with weekly bonuses added to study compensation. Following the four weeks of study-directed use, participants will continue with self-directed use. At four months, participants will then complete a booster session with two additional weeks of study-directed use, followed by self-directed use until the end of the study. The structure with the booster session has evidence for maintaining treatment gains and is also in alignment with the commercialization plan.

Group Type EXPERIMENTAL

Personalized circadian mHealth

Intervention Type OTHER

SHIFT is a mobile application designed to improve sleep in night shift workers. The SHIFT mobile application is used to collect data from an Apple Watch to assess an individual shift worker's body-clock timing and make personalized recommendations of light exposure schedules that are designed to align the body-clock with the night shift work schedule.

Waitlist Control

Participants in this condition will only complete questionnaires for the initial eight months. Those who remain shift workers will have the option of receiving the SHIFT app and the option to complete follow-up surveys in the same manner as the SHIFT App condition.
