Offspring reported on perceived parental problem drinking with interview items derived from the Family History of Alcoholism Module (FHAM) a reliable instrument utilized in the Collaborative Study on the Genetics of Alcohol (COGA) project (Rice et al. 1995). Offspring reporting that they thought their mother or father were ever excessive drinkers or that drinking ever caused their mother or father to have problems with health, school, family, police or other problems were coded as having a parent who was a problem/excessive drinker.
