An empirical typology of heroin abusers

Abstract
The MMPI [Minnesota Multiphasic Personality Inventory] profiles of 59 participants in a VA [Veterans Administration] Drug Abuse Program [St. Louis, Missouri, USA] were analyzed. A total of 8 types were defined by factor analysis. Three of the groups accounted for 60% of the subjects. The 3 groups had profiles that involved elevations on scales 2, 4, 8 and 9.
