For the second and third cohorts' baseline assessments, and for all cohorts' follow-up assessments, participants reported on their recent alcohol use with ordinal frequency and quantity items from the Alcohol Use Disorders Identification Test (Bush, Kivlahan, McDonell, Fihn, & Bradley, 1998). Frequency of alcohol use was assessed with the question “How often do you have a drink containing alcohol?” and the response options were never, monthly or less, 2 to 4 times a month, 2 to 3 times a week, 4 or more times a week, and I choose not to answer. Quantity of alcohol use was assessed with the question “How many drinks containing alcohol do you have on a typical day when you are drinking?” with response options 1 or 2, 3 or 4, 5 or 6, 7, 8 or 9, 10 or more, and I choose not to answer.
