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

Area of Science:

• Psychiatry
• Developmental Psychology
• Behavioral Genetics

Background:

• Antisocial behavior in alcoholic men has historically aided in subtype classification.
• The utility of this subtyping for identifying offspring at risk for alcoholism is under-researched.

Purpose of the Study:

• To investigate if family alcoholism subtypes, specifically antisocial alcoholism, predict distinct risk profiles in offspring.
• To examine the persistence of these risk differences from early to middle childhood.

Main Methods:

• Prospective study design.
• Assessment of preschool-aged children for risk indicators including temperament, externalizing behaviors, and hyperactivity.
• Follow-up assessments into middle childhood.

Main Results:

• Children from families with antisocial alcoholism exhibited higher risk indicators (temperament, behavior problems, hyperactivity) compared to other groups.
• These risk differences were evident in early childhood and sustained into middle childhood.
• Differences between non-antisocial alcoholic families and non-alcoholic control families were minimal.

Conclusions:

• Family alcoholism subtype, particularly the presence of antisocial behavior in fathers, is a significant predictor of offspring alcoholism vulnerability.
• Early childhood risk indicators associated with antisocial alcoholism are persistent.
• This subtyping strategy is valuable for identifying specific familial risks for alcoholism in offspring.
