33.8% of the participants (N = 2,318) met DSM-IV criteria for alcohol dependence during their lifetime, with 77.6 % of those endorsing ≥6 (i.e., severe) DSM-5 AUD criteria. A median of 14.0 drinks (SD = 12.9; ~96 grams of alcohol, or 14 standard US drinks) in a single 24-hour period was reported (i.e., MaxDrinks). 90.0% of the participants reported drinking at least once a month for 6 consecutive months or longer (i.e., monthly alcohol use).
