Sd. Husband et My. Iguchi, COMPARISON OF MMPI-2 AND MMPI CLINICAL-SCALES AND HIGH-POINT SCORES AMONG METHADONE-MAINTENANCE CLIENTS, Journal of personality assessment, 64(2), 1995, pp. 371-375
Methadone client volunteers completed the Minnesota Multiphasic Person
ality Inventory (MMPI; Hathaway & McKinley, 1967) and MMPI-2 (Butcher,
Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) on consecutive days. MM
PI-2 T-scores were lower by a mean of 4.7 on the clinical scales; when
5 points were added to MMPI-2 T-scores the mean difference was 2.3. R
ank order of subjects on scale T-scores was not significantly differne
nt between the two instruments. High-point similarity for clinically e
levated profile pairs ranged from 61% to 92%, depending upon definitio
n of similarity.
