RAPI, Rutgers Alcohol Problem Index; Max drinks, maximum number of drinks consumed in a 24-h period; AD, alcohol dependence; WAIS-R, Wechsler Adult Intelligence Scale – Revised.

All analyses adjust for gender and age.

Model II adjusts for co-morbid Axis I disorders and antisocial personality.

Model III adjusts for age at initiation of daily smoking and age at initiation of drinking to intoxication.

Model IV adjusts for low education.

Model V adjusts for all covariates.
