Personality disorder correspondence among the MMPI, MBHI, and MCMI

Abstract

MMPI, MBHI, and MCMI personality disorder scales were analyzed for convergent and discriminant validity. Friedman's ANOVA indicated that there were no significant differences among the sample's averaged scale scores. Further analyses of these data, however, demonstrated that the Millon instruments classified significantly more of the sample as personality disordered when compared to Morey's MMPI personality disorder scales. In addition, codetype correspondence among the three instruments was only 4 to 6%. When the instruments were analyzed in a pair‐wise fashion, codetype correspondence increased to approximately 10 to 20%. These data indicate that these personality disorder scales do not demonstrate construct equivalence, particularly at the level of the individual profile.

“…These component score correlations (factor score correlations) measure component similarity, and may thus provide a pattern of convergent and discriminant validity. Significant correlations between conceptually similar components of the different sets add to the construct validity of both instruments and support the utility of combining the two instruments, as each instrument enriches and refines data obtained from its counterpart (Antoni et al, 1985;Wise, 1995).…”
