Smartphone-Based Intervention for Sleep Disturbance in Individuals Recovering From Alcohol Use Disorder

Individuals will be randomly allocated to receive the full Health Rhythms package (CueToSleep) program on their smartphones. The package includes 24/7 behavioral sensing from the participant's smartphone using the global positioning system, accelerometer, and screen on/off state, as well as a series of psychoeducational learning screens about the relationship among alcohol, mood disturbance and sleep, and personalized suggestions for behavior change to improve sleep that will be sent to the participant every 3 to 4 days. These suggestions will be based on behaviors indicated by the individual participant's sensor data over the previous 3 to 4 days.
