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.
我们描述了292名4至17岁威廉姆斯综合征(WS)患者在考夫曼简易智力测验第二版(KBIT - 2;考夫曼与考夫曼,2004年)上的表现。相对于普通人群,智商综合平均分、言语标准分数(SS)和非言语SS处于临界范围,其变异性与普通人群相似。SS与年龄(CA)之间的相关性接近0,且无显著性别差异。母亲教育程度对言语SS有显著影响。对于所测量的能力,KBIT - 2能够恰当地反映8至17岁WS患者的全部表现范围,以及除功能最低的5至7岁儿童外所有WS儿童的表现范围。然而,KBIT - 2没有足够简单的项目来充分评估4岁儿童中最低四分位数的能力。
