the number of alcohol-related abuse and dependence symptoms in the past year. We used a quantity-frequency index (QFI) of alcohol use adapted from Cahalan, Cisin, and Crossley (1969) to obtain a measure of average daily ethanol intake for both parents. Finally, two measures of heavy drinking were obtained. The first indicated the frequency of getting drunk, the second indicated the frequency of drinking 5 or more drinks on a single occasion. As described above, families were placed in one of two groups on the basis of phone screen and questionnaire data: (1) the nonalcoholic group and (2) the father alcoholic group.
