Little research has focused on the range of drinking styles within a particular society. The intent of this study was to continue the development of an empirical typology of drinking behavior by replicating and extending the results of two previous projects. The earlier work had looked mainly at "normal" drinking, while this study placed more emphasis on types of problem drinking and on the relationships among various types of "normal" and "problem" drinking. The data were taken from a 1979 national probability sample of the adult population of the United States, with 1,169 cases classified as current drinkers. The results clearly showed that a variety of drinking styles exist, regardless of whether one is concerned with "normal" or "pathological" drinking. More importantly, certain types of "normal" drinking and types of comportment while drinking were powerful predictors of "problem" drinking.
