Psychosocial functioning of children: relations between personality subtypes and academic achievement

Five hundred children from ages 6 to 12 who had been referred for neuropsychological assessment were clustered into six subtypes using a k-means technique applied to 10 PIC scales. Five of the six subtypes were virtually identical to subtypes identified in previous research (viz., normal, somatic concern, mild anxiety, externalized psychopathology, and internalized psychopathology). A sixth subtype (conduct disorder) was also found. Wide Range Achievement Test (WRAT) Reading and Spelling scores discriminated between normal, somatic concern, and conduct disorder subtypes on the one hand vs. the more disturbed externalized and internalized psychopathology subtypes on the other; the latter groups scored higher on these measures. The internalized psychopathology subtype also showed large discrepancies between reading vs. arithmetic and spelling vs. arithmetic. The results support the view that psychosocial functioning is related to assets and deficits in cognitive/academic functioning in children, and that particular patterns of such assets and deficits are related to particular forms of psychopathology.
