title: Two types classification of male alcoholism confirmed.
abstract: In recent years a two types classification of male alcoholism has been proposed by several authors. The study aimed at a testing of type I/type II classification of alcoholism in an independent sample. A total of 351 Research Diagnostic Criteria (RDC) male alcoholics consecutively admitted for an inpatient psychiatric treatment were studied. Type II characteristics were extracted from the pertinent literature; 19 available variables best representing these characteristics were selected. The data was collected using the method of a retrospective evaluation of clinical records. Cluster analysis yielded two clusters which were well separated from each other. Heterogeneity of the male inpatient population of alcoholics was demonstrated and the existence of broadly defined type I and type II alcoholism was confirmed.
