Drinker categories for survey 1

Definitions

Each student belongs to exactly one drinker category. Drinker category is determined by the number of standard drinks students had on the day of their highest alcohol consumption in the past two weeks. Because, on average, the same amount of alcohol affects males and females differently, drinker category is also influenced by biological sex. For example, a male who consumed 4 drinks on a single day would be classified as a “moderate drinker,” while a female consuming the same amount would be a “heavy episodic drinker.”
