Two types of classification in female alcoholism.

Two types of alcoholism with distinct clinical features and mode of inheritance have been identified in male alcoholics. The relevant studies, however, have given consistent results in men but not in women. The current study tested the hypothesis that the type I and II classification is also valid in women. A sample of 103 hospitalised alcohol-dependent women were given face-to-face structured interviews considering four different classification criteria sets devised for differentiation of alcoholism type I and II and type A and B along with SCID I and II. The two types of classification could be replicated with three of the four criteria sets, 73 women being allocated to the larger cluster C1, and 30 women to a smaller cluster C2. Comparing the patients from both clusters with each other, eight variables were identified which excellently discriminate between the groups. The two types of classification for alcoholism could also be found in a female sample. A type II of female alcohol-dependent patient was identified, characterized by parental alcoholism and paternal and patient's tendency for violent behavior. Type I lacks these characteristics. Early identification of the type II female alcoholic may be clinically important.
