Borderline psychopathology and the defense mechanism test
1992 (English)Doctoral thesis, comprehensive summary (Other academic)
The main purpose of the present studies has been to develop the Defense Mechanism Test (DM1) for clinical assessment of severe psychopathology with the focus on the concept of Borderline Personality Organization (BPO) according to Kemberg. By relating the DMT and the Structural Interview to each other, the concurrent validity of the concept of Personality Organization (PO) for psychiatric inpatients has been investigated. Two different assessment approaches have been used for this purpose. One has been to take a theoretical perspective as the starting-point for the classification of PO by means of the DMT. The other has been a purely empirical approach designed to discern natural and discriminating patterns of DMT distortions for different diagnostic groups. A dialogue is also in progress between DMT and current research on the Rorschach test in order to increase understanding of borderline phenomena and pathology.
The overall results support Kemberg's idea that borderline patients are characterized by specific intrapsychic constellations different from those of both psychotic and neurotic patients. Both the DMT and the Structural Interview provide reliable and consistent judgements of PO. Patients with the syndrome diagnosis Borderline Personality Disorder exhibit different perceptual distortions from patients suffering from other personality disorders. The classic borderline theory is a one-dimensional developmental model, where BPO constitutes a stable intermediate form between neurosis and psychosis. The present results suggest that a two-dimensional model might be more powerful. Hence, the level of self- and object representations and reality orientation might be considered both from a developmental gad an affective perspective across varying forms of pathology.
Kemberg suggests that borderline and psychotic patients share a common defensive constellation, centered around splitting, organizing self- and object representations. This view did not find support. The defensive pattem of the BPO patients is significantly different from the PPO defensive pattern. The BPO patients form their self- and object images affectively and thus the self- and object representations would seem to influence the defensive organization and not the other way around. The results have implications for the procedure and the interpretation of the DMT e.g. one and the same DMT picture can discern different kinds of personality; reactions other than the operationalized defense categories in the DMT manual can be valid predictors of PO; some of the DMT defenses described in the manual have to be reconceptualized such as isolation, repression and to some degree denial. Multivariate models are powerful tools for the integration of reactions to DMT into diagnostic patterns.
