WISC scatter and behavioral competence in high-risk children

Examined the relationship between WISC scatter and school competence measures for 101 boys at risk for psychiatric disorder. This sample, shown in previous research to be less competent in school than controls, was predicted to have greater scatter than a standardization sample. Further, within the high-risk sample, an association was predicted between two measures of scatter and lowered school competence, as measured by Fisher's (1980) peer and teacher ratings. The results suggested that the mean scatter variable available for both samples is significantly higher in the high-risk group than in the intelligence test standardization sample. This scatter measure also measures. The second measure did not relate significantly to any of the school measures. These findings suggest that one of the two scatter measures is a valid index of less competent school functioning and may be in combination with other measures, a useful predictor of future psychopathology.
