Abstract excerpt

OBJECTIVE: The purpose of this study was to develop a quantitative measure of alcohol consumption for gene-mapping studies. METHOD: Using a sample of 3,787 young-adult twin women and an independent sample of 489 men and women from a college drinking study, we developed an alcohol-consumption factor score indexed by (1) maximum typical consumption (log-transformed quantity frequency [LQNTFRQ]), (2) maximum drinks...
