Autism spectrum disorders (ASD) are characterized by early impairments in language and related social communication skills. This investigation explored whether scores on the MacArthur-Bates Communicative Development Inventory (CDI) at ages 2 and 3 years predict outcome at age 9 years in children with ASD and developmental delay (DD).
Sixty-two children referred for possible autism at age 2 years, and 19 children with DD, were followed to age 9 years. Vocabulary, prespeech, and gestures scores on CDIs administered at ages 2 and 3 years were used to predict follow-up IQ, language, adaptive skills, and scores on diagnostic measures.
CDI scores at ages 2 and 3 did not predict outcome for the DD group. For the ASD sample, CDI receptive and expressive language and late gestures at ages 2 and 3 years predicted a number of follow-up variables, although scores at age 3 years were generally more predictive than scores at age 2 years.
The CDI yielded scores that were predictive of outcome, suggesting that this parent report measure may be a quick and informative assessment of early verbal and nonverbal skills in children with ASD.
自闭症谱系障碍（ASD）的特征是在语言及相关社交沟通技能方面存在早期缺陷。本研究探讨了2岁和3岁时的麦克阿瑟-贝茨沟通发展量表（CDI）得分是否能预测患有ASD和发育迟缓（DD）的儿童在9岁时的结局。
对62名2岁时被转诊可能患有自闭症的儿童以及19名患有DD的儿童进行追踪，直至他们9岁。使用2岁和3岁时进行的CDI中的词汇、言语前和手势得分来预测随访时的智商、语言、适应技能以及诊断测量的得分。
2岁和3岁时的CDI得分无法预测DD组的结局。对于ASD样本，2岁和3岁时的CDI接受性和表达性语言以及后期手势得分可预测多个随访变量，不过3岁时的得分通常比2岁时的得分更具预测性。
CDI得出的得分具有结局预测性，这表明这种家长报告测量方法可能是对ASD儿童早期语言和非语言技能进行快速且信息丰富的评估手段。
