Abstract
The patterns of appearance of alcoholism were studied in the families of 2 groups: 90 male and female alcoholic inpatients and 30 control psychiatric inpatients. There was at least one 1st-degree- or one 2nd-degree-relative family member who was diagnosed as alcoholic in 78% of the male alcoholic proband families and in 75% of the female alcoholic proband families. Prevalence of alcoholism for 1st- and 2nd-degree relatives was similar. This pedigree study supports the genetic transmission hypothesis for alcoholism and suggests that assortative mating may have an effect on the transmission of alcoholism.
