Perceptual Defenses and Self-Rated Personality Disorders: A Multivariate Analysis

Abstract

The relationships between defense mechanisms and personality disorders were explored by means of the Defense Mechanism Test and Millon's Inventory-II in a group of 100 psychiatric nonpsychotic outpatients. Only few significant positive nonparametric correlations were found, concerning barrier isolation, intro-aggression, and lack or lateness of the threat. Also a multiple regression analysis evidenced few significant results and mostly in the negative direction. The unpredicted findings may have been partly determined by a general elevation of personality scale scores (due to the emotional distress of psychiatric patients), leading to a loss of interindividual differences.
