Contrasting binge and continuous alcoholic drinkers using demographic and drinking history variables.

While it is quite common for researchers and clinicians to categorize alcoholics as binge or continuous drinkers, relatively little is known about the characteristics of these two potentially distinct clinical populations. In the present study, binge and continuous alcoholics were evaluated on a number of demographic and drinking history variables. Binge drinkers were found to be significantly more likely than continuous drinkers to have been treated for liver problems and more likely to have reported parental alcoholism. They also tended to describe a greater number of alcohol-related arrests and hospitalizations. Six of the variables taken together yielded a discriminative function that was only moderately successful in classifying these drinkers. The potential clinical importance of objectively identifying binge versus continuous drinkers is discussed.
