Severity of DSM-III-R alcohol dependence: United States, 1988

One method of subtyping alcohol dependence is according to severity. Over 4000 respondents in a US national survey who met criteria for DSM-III-R alcohol dependence were classified as mildly, moderately or severely dependent, and the characteristics of each group were examined. The proportion of males was higher in the moderate and severe groups, and the greatest proportions of cases were concentrated in the younger ages in all three groups. A clear increasing gradient from the mild to severe group was found for early age at first drink, heavy alcohol consumption, family history of alcohol problems, social pressure to reduce drinking, and helpseeking, treatment or AA for drinking. Implications for further analyses are discussed.
