Abstract
|
|
|
Present study was to examine the differences in responses of psychological tests among the childhood depression, the depressive-conduct disorder, and the conduct disorder groups. And to explore in which dimension drawn from those of psychological
tests
using MDS the above three groups would be classified to clarify the validity of the depressive-conduct disorder as a diagnostic entity and the comorbidity between the depression and the conduct disorder. 20 depressives, 20 depressive-conduct
disordered,
and 14 conduct disordered with the age from 7 to 12 were selected based on DSM-IV and ICD-10 criteria, and their responses of psychological tests including KEDI-WISC, BGT, and Rorschach were analyzed. The results revealed that for KEDI-WISC
subtests the
conduct disorder group showed higher scores in the comprehension and the picture arrangement, and lower score in the block design than did the other groups. Also conduct disorder group gave more OBS signs in BGT. These results suggest that
conduct
disordered children have better social skills and higher probability of brain dysfunction than did depressive and depressive-conduct disordered children. In Rorschach responses the depression group showed more morbid content than did the other
groups,
indicating the potential usefulness of morbid content in diagnosing depression in children. The finding of MDS revealed that the depression and the depressive-conduct disorder groups are closer each other in dimension drawn from KEDI-WISC
subtests,
while the depressive-conduct disorder and the conduct disorder groups are closer in dimension drawn from Rorschach. These results put together suggest the validity of depressive-conduct disorder as a diagnostic entity. But the result of MDS for
both
KEDI-WISC and Rorschach showed that the depressive-conduct disorder group is more similar to the depression group than to the conduct disorder group, implying that depressive-conduct disorder might correspond to so called masked depression. It
was
suggested that the dimensional approach may compensate the limitations of the categorical approach such as DSM-IV in classifing psychiatric disorders.
