BACKGROUND This study examined whether IQ predicts neuropsychological performance among children with varying ability levels. METHODS 177 children/adolescents were subdivided as Below Average (BA; N = 71; IQ = 60-85), Average (A; N = 72; IQ = 90-110), or Above Average (AA; N = 34; IQ = 115-140) in IQ. Assessments included intelligence, achievement, memory, and executive functioning measures. RESULTS Group differences were found on all tests (p < .001). Planned comparisons revealed differences between BA and A on seven variables, and between A and AA on five variables with small-to-medium effect sizes. Correlations were found between IQ and neuropsychological functioning and varied by group membership. CONCLUSIONS In children, IQ predicts neuropsychological performance differentially based upon ability level, with stronger relationships shown in lower IQ ranges.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
