ABSTRACT
We examined the correspondence between college students' ( N = 192, 71% women) definitions of free-pours and their free-poured volumes of beer, wine, and liquor. Participants' mean beer definitions and free-pours were positively correlated; participants' mean wine and liquor definitions were larger than their free-pours, which were fairly accurate. Contrary to what the aggregate mean values indicated, fewer than half of the participants accurately free-poured a standard volume of beer, wine, or liquor (37.4%, 35.1%, and 22.2%, respectively) or provided an accurate definition of beer (45.8%); similar to the aggregate data, few participants provided accurate definitions of standard serving of wine (12.2%) or liquor (12.8%) Instead, a majority of participants' definitions and free-pours were well over or under a standard serving. For all three types of alcohol, there was little correspondence between each individual participant's definitions and his or her free-poured volumes. These data suggest analyses of individual data points may provide information important for data collection, prevention, and intervention strategies.
