Brief Summary

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

This study aims to identify risk factors that prospectively predict alcohol problems in young adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The vast majority of alcohol use takes place in social settings, yet nearly all human experimental work has administered alcohol to individuals in isolation. This study will examine the effects of alcohol in social groups and test whether these responses predict the escalation of alcohol use and development of alcohol use disorder symptoms. Participants will also complete smartphone surveys querying subjective responses to alcohol in their daily lives.

N=400 male and female young adults will participate in a laboratory session with two other participants and will consume either a moderate dose of alcohol or placebo beverage. Subjective and objective responses to alcohol will be assessed. Participants will also complete surveys on their smartphones; these will occur during drinking episodes and at random times throughout the day. Follow-up sessions will occur at 6-months and 12-months, to collect information about drinking habits and potential alcohol-related problems.
