Comparison of MMPI scores of drug abusers and Mayo clinic normative groups

Abstract

Compared MMPIs of 80 male and 80 female drug abusers with MMPIs of 550 male and 695 female Mayo Clinic medical patients. Male drug abusers obtained significantly higher scores than male medical patients on all of the clinical scales and the F scale. They obtained a significantly lower score on K. Female drug abusers obtained significantly higher scores than female medical patients on seven clinical scales, D, Pd, Pa, Pt, Sc, Ma, and Si. They scored significantly higher on F and lower on L and K. Male and female drug abusers scored above 70 on Pd, Sc, and Ma, whereas medical patients did not exceed 60 on any scales. Findings were viewed as supporting the need for individualized, sophisticated, multidimensional psychological assessment and treatment of drug abusers in rehabilitation settings.
