Two items related to alcohol history were included. Participants were asked to report the age at which they started drinking, excluding small tastes or sips of alcohol. To assess family history of alcohol problems, participants were asked whether any of their relatives ever “had a significant problem with alcohol or drugs, one that either led to treatment or should have led to treatment.” The same definition of alcohol/drug problem was utilized in the Addiction Severity Index (McLellan et al., 1992). Participants reported on alcohol and drug problems separately and only alcohol problems are reported here. Those reporting an alcohol history for at least one parent were classified as family history positive.
