The psychiatric diagnosis of alcoholism: critique and proposed reformulation.

A taxonomy of alcohol problem involvement is proposed which encompasses categorical and dimensional approaches to classification. It is argued that contemporary nosology such as that described in DSM or ICD cannot, in principle, yield discrete categories containing homogeneous membership. Nor does current classification and diagnosis yield sufficient specific information necessary for effective treatment. These limitations are not resolvable by additional empirical research; rather, as discussed herein, a new conceptual framework and focus are required. The proposed new taxonomy comprises the first step in developing a comprehensive and clinically useful method for characterizing the alcohol consuming population.
