Frequency of binge drinking was assessed with the item: “During the last 12 months, about how often did you drink [5 (male)/4 (female)] or more drinks in a single day?” Response options included 11 categories ranging from “every day” to “never in the last year”. Frequency of binge drinking was treated as continuous using the midpoints of each category. Results are presented in number of days/week units. Additionally, respondents were classified as hazardous drinkers if they consumed more than 14 (men)/7 (women) drinks/week (as calculated by frequency of consumption × amount typically consumed), or if they reported at least one binge drinking episode during the past year, per NIAAA guidelines (US Department of Health and Human Services, 2007).
