Description
Summary:Three types were found in a cluster analysis of scores on the Minnesota Multiphasic Personality Inventory (MMPI) of 100 men voluntarily presenting for treatment of cocaine abuse. Type 1 (n = 59) had a mean MMPI profile consistent with the hypothesized grouping of persons who self-medicate with cocaine as a means of overcoming depression. The relatively normal mean MMPI profile obtained by Type 2 (n = 37) suggested little indication of significant psychopathology. Type 3's (n = 4) mean MMPI profile suggested either severe disturbance or profile invalidity. Types were found to differ in the nature of drug use, reactions to cocaine, education level, and social class, but not on the scales of the Adjective Check List.
