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

In order to assess the efficacy of the rhythm stabilization component of Health Rhythms' product in addressing sleep problems, investigators will recruit 128 outpatients over the age of 18, who are in early recovery (at least 2 weeks but no more than 6 months) from Alcohol Use Disorder (AUDIT-C score \>4) and are experiencing sleep problems (ISI score \>/= 10). 64 of these individuals will be randomly allocated to receive the full HealthRhythms package (sensing, trending, and stabilization) on their smartphones, while 64 will be asked to consent to sensing only. The duration of the study will be 14 weeks. The primary outcome measures of the RCT will be the ISI (Insomnia Severity Index). The investigators hypothesize that those receiving the full package will demonstrate lower levels of sleep disturbance.
