Behavioral Alcohol Responses (BAR) Study
Behavioral Alcohol Responses (BAR) Study
This study aims to identify risk factors that prospectively predict alcohol problems in young
 adults.
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.
