In two situations various comparisons were performed among the Peabody Picture Vocabulary Test (PPVT) and Raven's Coloured Progressive Matrices (RCPM) scores of 11 girls and 11 boys of preschool age (Study 1) and of 11 nonproblem and 11 behavior problem preschool children (Study 2). A possible sex difference was found: girls did obtain a significant correlation between the PPVT raw (or non-age-corrected) scores and the RCPM, whereas boys did not. Age and RCPM scores were significantly correlated (Study 1), but age and PPVT IQ scores were not. Thus, it appeared that scores on a measure of the spatial ability involved in the RCPM do increase progressively with age, although they are not related to the skills measured by the PPVT. In Study 2 a trend toward higher correlations was found between the RCPM and the PPVT scores for the nonproblem as compared to the problem children.

Six measures of adaptive behavior were compared to determine which tests and items best discriminate between behavior problem and nonproblem preschool children. Eleven nonproblem and 13 problem children, matched on age and IQ, were compared on the following tests: the Minnesota Child Development Inventory, the Classroom Adjustment Rating Scale, the Ottawa School Behavior Survey, the AML Behavior Rating Scale, the Teacher Rating Scale, and the Denver Developmental Screening Test. Problem children scored significantly lower than nonproblem children on all six measures. In addition, fine-motor items discriminated better than gross-motor, language, social, and behavioral items. The Minnesota Child Development Inventory items were the best discriminators, followed by items on the Ottawa School Behavior Survey and the Teacher Rating Scale.
