title: A study of schizophrenic outpatients with the Defense Mechanism Test.
abstract: Intrapsychic defensive strategies are allegedly expressed on the Defense Mechanism Test through the presentation, at increasing tachistoscopic exposure times, of a picture in which a central figure is threatened by a peripheral person. Several types of perceptual alterations of the stimulus configuration are coded as defenses in the subjective reports. A number of test variables have already been shown to differentiate significantly between nonclinical controls and nonpsychotic psychiatric patients. In the present study, after a review of the pertinent percept-genetic literature, nonpsychotic patients (n = 57) were compared with a group of schizophrenic outpatients in the active phase (n = 21). As predicted, significantly more schizophrenics than controls were coded for projection and regression and for certain variants of these signs. Four subcodings of repression, three of isolation, the sign of reaction formation, and several variants of identification differentiated in the same direction. Reports in which the central figure was too old and changed from a correct to an incorrect sex attribution were highly characteristic of the schizophrenic sample. No defensive variable was significantly linked with nonpsychotic pathology. Two variants, one of regression and one of identification, allowed a correct diagnostic placement for all schizophrenics and for 82.4% of the nonpsychotic patients. The findings, besides being a further clinical validation of the Defense Mechanism Test, provide a preliminary distinction between high- and low-level defenses. It is suggested that they are congruent with an hierarchical model which implies inclusive nonreflexive relationships between classes of mental disorders.
