Abstract
In recent years a number of investigators have utilized empirical techniques to develop classification schemes for alcohol related problems. This chapter examines this literature, reviewing both dimensional and categorical models that have been proposed. Despite much consistency in the methodologies that have been used, relatively few consistent substantive findings have emerged from these studies. However, increasing sophistication in the use of these empirical techniques over the past decade has produced some interesting results. One such study which yielded a hybrid model for alcoholism incorporating advantages of both categorical and dimensional approaches, is discussed in some detail. Finally, promising directions for future research are outlined with references to the implications of such taxonomy for alcoholism treatment and course.
