目的：目的评价麦克阿瑟婴幼儿沟通发展量表（MCDI-I; L。Fenson等人，1991），一个父母报告的早期词汇量的测量，可以改善自闭症谱系障碍（ASD）儿童通过删除有偏见的项目。如果被测量的特征以外的其他特征改变了一个人正确获得一个项目的概率，则项目被认为是有偏差的。目前研究的参与者包括272名年龄小于18个月的典型发育婴儿和209名年龄大于18个月的ASD幼儿。2组之间的年龄差异是匹配的结果，总大小的接受vocabulary.Results：25个项目被确定为显示大的bias.Conclusion：删除这些项目的测试应该增加的程度，作者正在测量的受访者的心理词汇的总得分从MCDI-I的大小。
Purpose: To evaluate whether the validity of the Receptive Vocabulary scale of the MacArthur Communicative Development Inventory for Infants (MCDI-I; L. Fenson et al., 1991), a parent-report measure of early vocabulary, could be improved for children with autism spectrum disorders (ASD) by removing items that are biased.Method: Logistic regression was used to identify biased items. Items are considered biased if characteristics other than those being measured by the instrument change the probability that a person will get an item correct. Participants in the current study included 272 typically developing infants younger than 18 months of age and 209 toddlers with ASD older than 18 months of age. The age difference between the 2 groups is a result of matching on total size of the receptive vocabulary.Results: Twenty-five items were identified as showing large bias.Conclusion: Deletion of these items from the test should increase the degree to which the authors are measuring the size of the respondent's mental lexicon with the total score from the MCDI-I.
