Alcohol use was evaluated with a variation of the measure used by White and Labouvie (1989). The instructions defined 1 alcoholic drink as “one beer, one glass of wine, or one serving of hard liquor either by itself or in a mixed drink” (White and Labouvie, 1989). The following 3 questions about drinking patterns in the last year were asked as part of the Alcohol Consumption Questionnaire (ACQ): (1) When you drank alcohol, how many drinks did you consume on average on 1 occasion? (ACQ1); (2) What is the largest number of drinks you consumed on 1 occasion? (ACQ2); and (3) How often you drank alcohol on average? (ACQ3). The last question was answered on a 10-point scale ranging from “never” to “every day” and where 6 = twice per week. Average scores on drinking measures are presented in Table 1.
