Millon's basic personality styles as measured by the Personality Adjective Check List (PACL; Strack, 1987, 1991b) were linked to Minnesota Multiphasic Personality Inventory‐2 (MMPI‐2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) basic scales via bivariate correlation and factor analysis in independent samples of psychiatric patients ( N = 196) and normal adults ( N = 124). Consistent with previous research, Millon's neurotic, introverted styles were positively associated with MMPI‐2 scales measuring introversion, affective states, and disturbed thinking, whereas extroverted, socially dominant Millon styles were negatively associated to the same scales. Millon personalities and MMPI‐2 scales were reliably associated along two bipolar dimensions measuring Neuroticism/Introversion versus Extroversion and Emotional Distress versus Emotional Stability, which accounted for 45% of the variance. A third General Distress factor loaded only MMPI‐2 scales. Congruency coefficients indicated that the factors for patients and normal participants were very similar. Results highlighted the consistency of the links between MMPI‐2 basic scales, the PACL, and other Millon instruments, as well as the utility of the PACL as a measure of Millon's personality styles in a mental health population. © 1999 John Wiley & Sons, Inc.
