The Development of Alcoholic Subtypes: Risk Variation Among Alcoholic Families During the Early Childhood Years

Lifetime differences in antisocial behavior among alcoholic men historically have been useful in distinguishing alcoholic subtypes. However, the usefulness of this subtyping strategy for identifying differences in families that may put offspring at risk for developing later alcoholism has not been previously documented. Findings from a prospective study on the development of vulnerability for alcoholism among (initially) preschool-age children showed that children from families with antisocial alcoholism differ on a number of indicators of child risk, including measures of risky temperament, externalizing behavior problems, and hyperactivity. Risk differences among children from these family subtypes appear to be sustained into middle childhood. Differences between nonantisocial alcoholic families and nonalcoholic control families were less distinguishable in both early and middle childhood.
