The Wechsler Intelligence Scale for Children, 4th edition (WISC-IV) is often used to assess children with traumatic brain injury (TBI); although limited information is available regarding its psychometric properties in these children. Two recent reports suggest that the Perceptual Reasoning Index is not uniquely sensitive to TBI, which differs from the Perceptual Organization Index of the WISC-III. The current study examined WISC-IV profiles in two independently gathered samples of children with TBI. Examination of profiles indicated similarities between the current findings and those reported in other studies, in that the greatest deficits were present on the Processing Speed Index and its component subtests of Coding and Symbol Search, while the Perceptual Reasoning index score was comparable to the Verbal Comprehension Index. Also, no significant index or subtest score differences were present when the current sample was compared to the children with TBI reported by Allen, Thaler, Donohue and Mayfield (2010 ). The present findings are consistent with two prior studies of the WISC-IV in children with TBI, providing additional evidence for profile differences between the WISC-III and WISC-IV. The results also suggest that WISC-IV profiles reported in prior studies are generalizable across TBI samples and study sites.
韦氏儿童智力量表第四版（WISC-IV）常用于评估患有创伤性脑损伤（TBI）的儿童；尽管关于其在这些儿童中的心理测量特性的信息有限。最近有两份报告表明，知觉推理指数对 TBI 的敏感性不是独特的，这与 WISC-III 的知觉组织指数不同。本研究在两个独立收集的 TBI 儿童样本中检查了 WISC-IV 图谱。对图谱的检查表明，当前的发现与其他研究报告的结果相似，即最大的缺陷存在于加工速度指数及其组成分测验的编码和符号搜索，而知觉推理指数与言语理解指数相当。此外，当将当前样本与 Allen、Thaler、Donohue 和 Mayfield（2010 年）报告的 TBI 儿童进行比较时，没有发现显著的指数或分测验得分差异。目前的研究结果与之前两项关于 TBI 儿童 WISC-IV 的研究一致，为 WISC-III 和 WISC-IV 之间的图谱差异提供了额外的证据。研究结果还表明，之前研究报告的 WISC-IV 图谱在 TBI 样本和研究地点之间具有通用性。
