P. Fransson et E. Sundbom, DEFENSE-MECHANISM TEST (DMT) AND KERNBERGS THEORY OF PERSONALITY ORGANIZATION RELATED TO ADOLESCENTS IN PSYCHIATRIC-CARE, Scandinavian journal of psychology, 38(2), 1997, pp. 95-102
75 adolescent psychiatric patients were diagnosed with the perceptual
projective test the Defense Mechanism Test (DMT) and also according to
Kernberg's theory of personality organization (PO). The test protocol
s were scored in respect of 130 DMT variables and analyzed by means of
partial least squares (PLS) discriminant analysis. The objective was
to try to separate the three types of PO, psychotic (PPO), borderline
(BPO) and neurotic (NPO) by means of the DMT and also to compare the r
esults with a similar study on adult psychiatric patients. The results
showed that it is possible to separate significantly the three groups
of PO. The BPO group seemed to be heterogeneous. The results were fai
rly similar to those obtained with adult psychiatric patients. The ove
rall results supported the concurrent validity of Kernberg's theory of
PO and for the DMT as well. The DMT seems to be a useful diagnostic m
ethod in respect of adolescent psychiatric patients.
