The author presents data on the Minnesota Multiphasic Personality
Inventory (MMPI) characteristics of a sample of enlisted Army men returning
from Viet Nam identified as heroin abusers. Although a marked heterogeneity
of MMPI profile types was found, a significant percentage of the subjects
showed indications of marked psychopathology, and only a minority performed
within normal limits on the MMPI. Theses military subjects showed neither
greater nor less psychopathology and sociopathology than previously
reported samples of civilian addicts.
