MCMI-II Personality Traits Associated with the MMPI-2 Masculinity-Femininity Scale

Abstract

There has been limited research into the behavioral correlates associated with the Masculinity-Femininity (Mf) scale of the MMPI (and the MMPI-2). In this study, both the Millon Clinical Multiaxial Inventory—II (MCMI-II), a frequently used self-report measure of personality functioning, and the Minnesota Multiphasic Personality Inventory–2 (MMPI-2) were administered to a group of 76 female psychiatric inpatients. The sample was divided based upon MMPI-2 Mf scale T scores. Subjects with a T score >50 were assigned to the high-Mf group (n = 28), whereas subjects with a T score >50 were assigned to the low-Mf group (n = 48). The two groups were compared across the 13 personality disorder scales of the MCMI-II. The results showed that subjects in the high-Mf group had significantly higher scores on the MCMI-II Narcissistic, Antisocial, Aggressive/Sadistic, and Paranoid personality disorder scales. A correlational analysis revealed that the MMPI-2 Mf scale was significantly correlated with these four MCMI-II personality disorder scales. These results are discussed in light of their clinical implications and the limitations of the study.
