Behavioral Alcohol Responses (BAR) Study
Predicting Alcohol Use and Alcohol Use Disorder Symptoms From Subjective Responses to Alcohol in a Laboratory Social Setting
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
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.

Measure Description |
Time Frame |
---|---|---|
Subjective Responses to Alcohol
Time Frame: 1 day (laboratory session) and 21-day ambulatory assessment period
|
Participants will indicate how they feel after drinking alcohol using the Brief-Biphasic Alcohol Effects Scale, which is a 6-item scale assessing alcohol's acute stimulant and sedative effects (0-10 scale, with higher scores indicating higher values).
|
1 day (laboratory session) and 21-day ambulatory assessment period
|
Social Bonding
Time Frame: 1 day (laboratory session)
|
Facial expressions of emotions using Paul Ekman's Facial Action Coding System (FACS).
The duration of AUs associated with positive and negative affect will be coded.
|
1 day (laboratory session)
|
Social Bonding
Time Frame: 1 day (laboratory session)
|
Perceived Group Reinforcement Scale, which is a 12-item scale assessing self-reported bonding (1-9 scale, with higher scores indicating more bonding).
|
1 day (laboratory session)
|
Mood
Time Frame: 1 day (laboratory session)
|
8-item Mood Measure, which is an 8-item scale assessing mood items from each of the four quadrants of the affective circumplex (with higher scores indicating more felt emotion).
|
1 day (laboratory session)
|
Alcohol Use
Time Frame: 21-day ambulatory assessment period
|
Quantity of standard drinks consumed.
|
21-day ambulatory assessment period
