Different definitions of alcoholism, I: Impact of seven definitions on prevalence rates in a community survey

Abstract
Seven different sets of diagnostic criteria for alcoholism were applied to data obtained by using the Schedule of Affective Disorders and Schizophrenia (SADS) in a community sample. They found that the different diagnostic schemes for alcoholism are hierarchical in the sense that some definitions identify smaller groups of subjects as alcoholic than do other definitions. A potentially useful empirical approach to comparing diagnostic criteria for psychiatric disorders in epidemiologic or clinical studies was shown.
