Aim:
In order to study the role of imitation in relation to drinking, alcohol consumption among two peers was examined with experiments in a naturalistic drinking setting.
Method:
In a bar lab, 135 young adults (52% women) were exposed to either a non-drinking, a light-drinking or a heavy-drinking same-sex model (i.e. a confederate) in a 30-min time-out session. Instead of using a taste task (Quigley and Collins, 1999. The modeling of alcohol consumption: a meta-analytic review. J Stud Alcohol 60:90-8) in which participants were obliged to consume alcohol, in the current study, a design was used in which participants were allowed to drink alcohol but could also choose non-alcoholic beverages.
Results:
Craving for alcohol was included as a covariate in ANCOVAs. Results showed that the participants consumed substantially more alcohol when exposed to heavy-drinking models compared to light- and non-drinking models. Craving levels were positively related to alcohol consumption during the experiment.
Conclusion:
Both men and women imitated same-sex peers' drinking behavior in an ad lib naturalistic bar setting.
