Novel Real-world Methods in Social Drinkers and AUD

During intake, a research assistant will demonstrate how to place the HRV monitor, BACtrak Skyn, and provide instructions on completing the saliva samples at home. Participants will wear the HRV and Skyn monitors for three consecutive, randomly selected days twice for individuals with Alcohol Use Disorder and once for social drinkers during the study (72 hours each). Participants will be provided with six saliva sample collection tubes per day with explicit directions on when the saliva sampling should occur (hours since waking: +0, +1, +2, +4, +6, +10 hours, and before going to sleep). Participants will also complete a subjective report using similar questions included in the survey prompts at the same scheduled time as the saliva sample. Individuals with Alcohol Use Disorder would complete a total of 6 such days during the study, and social drinkers would complete a total of 3 such days during the study.
