This study is being conducted to better understand alcohol use behaviors in young adults and how drinking patterns occur in everyday life. Researchers hope this information will help improve future research and interventions related to alcohol use and health.

You may be eligible to participate in this study if you meet the following criteria.

• Ages 18-25

• Drinks alcohol regularly

• Own an iPhone

Overall Duration

This study lasts about 2 weeks. Participants will complete one in-person baseline visit, 14 days of remote data collection, and one in-person follow-up visit.

In-Person Study Visits

Participants will attend two in-person visits at the study site in Tulsa, Oklahoma.

Baseline Visit (about 60 minutes):

• Learn how to use the study devices
• Complete a survey about alcohol use and related behaviors
• Receive a wrist-worn alcohol sensor and an Oura Ring to wear during the study

Follow-Up Visit (about 30 minutes):

• Return the study devices
• Complete any final study procedures

At-Home Activities

For 14 days, participants will:

• Wear a wrist-worn alcohol sensor and an Oura Ring throughout the study period
• Complete two brief surveys each day (about 3–7 minutes each)
• Complete short surveys while drinking alcohol (about 1 minute each)

The study devices and surveys help researchers learn more about alcohol use behaviors in everyday life.

Participants may receive up to $196 for completing all study activities. In addition to compensation, participants will contribute to research that aims to improve understanding of alcohol use behaviors in young adults. Participants may also gain personal insights into their own health and behavioral patterns through the use of study surveys and wearable technology. Transportation support or reimbursement is not available for this study.

There is no cost for you to participate in our research study.
