Children with autism spectrum disorder (ASD) display variable verbal cognitive profiles despite a historical requirement for a language delay in autistic disorder. This study compared the Verbal Comprehension Index (VCI) to the newly created ancillary index score, the Verbal Expanded Crystallized Index (VECI) of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) in a group of children with ASD. Using the ASD sample from the standardization data of the WISC-V, results indicated the VCI and VECI were significantly different for the ASD group but not for the matched controls. Follow up analysis of the ASD group revealed the VCI and VECI were significantly different for those with language impairment but not for those without language impairment. Psychologists should consider administering all verbal subtests of the WISC-V to children with ASD given the VECI may better capture the language impairment seen in this population.

自闭症谱系障碍儿童在WISC-V上的语言表现比较

患有自闭症谱系障碍 (ASD) 的儿童表现出不同的语言认知特征，尽管历史上要求自闭症患者出现语言延迟。本研究在一组患有 ASD 的儿童中将语言理解指数 (VCI) 与新创建的辅助指数分数、韦氏儿童智力量表第五版 (WISC-V) 的语言扩展结晶指数 (VECI) 进行了比较。使用来自 WISC-V 标准化数据的 ASD 样本，结果表明 ASD 组的 VCI 和 VECI 显着不同，而匹配的对​​照组则没有。对 ASD 组的后续分析显示，有语言障碍的人的 VCI 和 VECI 有显着差异，而没有语言障碍的人则没有。
