Abstract: Objective　To assess the correlation between the Verbal Comprehension Index（VCI）of Wechsler Preschool and Primary Intelligence Scale （WPPSI-IV）and standardized language assessment tools，and to explore the application value of VCI in the assessment of the language ability of children with language disorders in ASD. Methods　From January 2019 to January 2020，69 children with ASD and 99 typical development children（TD）were selected as the subjects in the Division of Child Healthcare，Department of Pediatrics，Tongji Hospital，Tongji Medical College，Huazhong University of Science and Technology. We compared the VCI score in the WPPSI-IV scale with the overall language，listening comprehension，language expression，semantics and syntax in the Diagnostic Receptive and Expressive Assessment of Mandarin-Comprehensive （DREAM-C）. Results　The VCI of children with ASD language disorder was significantly correlated with DREAM-C listening comprehension（r=0.43）and semantics（r=0.48）（P<0.05）. VCI explained 15.10% of the variance of the overall DREAM-C language score. The correlation coefficients between VCI and DREAM-C listening comprehension（r=0.51），semantics（r=0.52），language expression（r=0.62）and syntax（r=0.50）of TD were statistically significant（P<0.05），and 31.34% of the variance of the overall language score of DREAM-C was explained by VCI. Conclusion　For the children in this study，the VCI index can predict part of the listening comprehension and semantic abilities of children with ASD，but due to the limited sample size，the research conclusions need to be verified by more clinical studies.

摘要： 目的　评估韦氏幼儿智力量表第4版（WPPSI-Ⅳ）言语理解指数（VCI）与标准化语言评估工具的相关性，探讨VCI在孤独症谱系障碍（ASD）语言障碍儿童语言能力评估中的应用价值。方法　选取2019年1月至2020年1月在华中科技大学同济医学院附属同济医院儿童保健科69例ASD共患语言障碍儿童和99名正常儿童为研究对象，比较其WPPSI-Ⅳ量表VCI得分与梦想语言标准化评估（DREAM-C）整体语言、听力理解、语言表达、语义和句法的相关性。结果　ASD语言障碍儿童的VCI与DREAM-C听力理解（r=0.43）和语义（r=0.48）显著相关（P<0.05），VCI解释了DREAM-C总体语言得分方差变异的15.10%；正常儿童的VCI与DREAM-C听力理解（r=0.51）、语义（r=0.52）、语言表达（r=0.62）和句法（r=0.50）的相关系数差异均有统计学意义（P<0.05），VCI解释了DREAM-C总体语言得分方差变异的31.34%。结论　针对该研究人群，VCI指数可预测ASD语言障碍儿童部分听力理解和语义能力，由于纳入样本量有限，研究结论需进一步开展临床研究证实。
