CORRESPONDENCE BETWEEN STUDENTS SCORES ON THE MILLON CLINICAL MULTIAXIAL INVENTORY-II AND PERSONALITY DIAGNOSTIC QUESTIONNAIRE-REVISED

The relation between two measures of personality disorders was examine d in a nonclinical sample of 113 college students (86 women, 27 men) w ho completed the Millon Clinical Multiaxial Inventory-II and the Perso nality Diagnostic Questionnaire-Revised. Raw scores for 10 of 11 corre sponding scales on the two instruments were significantly correlated ( median r=.49). Compared to Millon's inventory, the Personality Diagnos tic Questionnaire-Revised designated more subjects as having eccentric personality disorders but fewer as having anxious personality disorde rs. The significant association between scores on the inventories sugg ests thar they assess personality traits that vary continuously in non clinical samples. However, the finding that they differ significantly in their assignment of clinical labels shows that they should not be u sed to diagnose personality disorders in nonclinical populations.
