The average number of drinks a subject reports drinking each week. Most studies asked this question directly. Other studies have converted to grams per day, or grams per week. The latter are fine to analyze directly for our purposes.
Individuals who either never drank, or on whom we have no data (e.g., someone was a former drinker but former drinking was not assessed) will be excluded from analysis. Please combine all types of liquor in the total estimate. If preferable, repeated measures designs (longitudinal data) can use all assessments by scaling and correcting for covariates within waves of assessment, then averaging across assessments.
