Dimensions of alcoholism: a multivariate analysis.

The present study multivariately interrelated demographic and psychometric variables that have been extensively researched in the alcoholism literature. These variables included the essential-reactive continuum, degree of familial alcoholism, subjective distress, antisocial personality features and gender. Data were collected for 76 inpatients (56 male and 20 female) meeting DSM-III criteria for alcohol abuse/dependence. The mean age of the sample was 38.9 years and ranged in age from 18 to 69 years. Three factors with eigenvalues greater than 1 were extracted. Factor 1 was labeled Neuroticism, and measures of depression, anxiety, neuroticism and female gender had the highest loadings. Number of first-degree relatives with alcoholism, essential (early onset and greater severity) alcoholism and greater antisocial propensity had the highest loadings on Factor 2, labeled "Essential-Familial." The Extroversion scale of the Eysenck Personality Inventory and number of second-degree relatives with alcoholism loaded most highly on Factor 3, labeled "Extroversion." Theoretical and clinical implications associated with these dimensions of alcoholism and variously proposed alcoholic subtypes are discussed.
