The nature of alcoholism in patients with different family histories for alcoholism.

1. The course and consequences of alcohol abuse were examined in male and female patients being treated for alcoholism. 2. Demographic characteristics, family history for alcoholism, psychopathology, drinking history and social and physical consequences of alcohol abuse were assessed. 3. Probands with alcoholism on both the maternal and paternal sides of their pedigree experience greater psychosocial and physical consequences of alcohol abuse than other alcoholic patients. 4. Sex of the proband and type of family pedigree for alcoholism were found not to be interactive but to contribute separate additive effects.
