title: Typological analysis of MMPI personality patterns of drug dependent men.
abstract: This study replicated Types I and II of Berzins, Ross, English and Haley's (1974) initial typological research with a drug dependent sample. In this research, Minnesota Multiphasic Personality Inventory (MMPI) profiles of 447 drug dependent men were submitted to Johnson's (1967) hierarchical clustering procedure. The hierarchical clustering procedure yielded nine small but clinically meaningful personality subtypes. These types were compared to Berzin's (Berzins et al.) profiles and categorized into three diagnostic classes: character disorder, 42% of the sample; neurotic characters, 35% of the sample; and borderline disorder, 23% of the sample. The profiles were discussed with respect to the scale similarity and differences within the diagnostic class. The results were discussed, with implications for treatment and further research efforts with the drug dependent population.
