Performance on the Kaufman Brief Intelligence Test-2 by Children with Williams Syndrome
Pitts, C. Holley; Mervis, Carolyn B.
American Journal on Intellectual and Developmental Disabilities, v121 n1 p33-47 Jan 2016
We describe the performance of 292 4- to 17-year-olds with Williams syndrome (WS) on the Kaufman Brief Intelligence Test-2 (KBIT-2; Kaufman & Kaufman, 2004). Mean IQ Composite, Verbal standard score (SS), and Nonverbal SS were in the borderline range relative to the general population, with variability similar to the general population. Correlations between SSs and CA were close to 0, with no significant sex differences. There was a significant effect of maternal education on Verbal SS. The KBIT-2 appropriately captures the full range of performance of 8- to 17-year-olds with WS for the abilities measured and of all but the very lowest-functioning 5- to 7-year-olds. However, the KBIT-2 does not contain easy enough items to adequately assess the abilities of the lowest quartile of 4-year-olds.
