Abstract
This article describes the transformation of reported alcohol consumption into a quantitative variable, Standardized Alcohol Intake (SAI), which is used to investigate various sociodemographic and psychosocial factors as correlates of alcohol use in a total community sample (N = 1672), in Tecumseh, Michigan. Statistically significant relations were obtained between alcohol usage and marital status, education, smoking status, and church attendance with the latter accounting for the 15% of the variability in drinking. On measures of personality, SAI was positively and significantly associated with level of activity, sociability, impulsivity, and extraversion. For drinkers, their attitudes toward drinking and changes in mood varied significantly in relation to the amount consumed. These findings are important and necessary for the appropriate control of these correlates in the future study of familial aggregation of SAI in the Tecumseh community.
