自闭症谱系障碍(ASD)的主要诊断标准之一是存在语言延迟或障碍。患有自闭症的儿童现在被发现的年龄要小得多，先前的研究一直发现，这一群体的早期语言技能是不同的，是未来结果的重要预测因素。这项研究的目的是系统地调查患有自闭症的学步儿童的语言，并确定该人群中接受性语言和表达语言的早期相关性。这项研究包括164名年龄在18到33个月之间的自闭症幼儿，他们接受了几项认知、语言和行为测量。结果表明，早期语言的不同测量方法，包括直接评估和家长报告测量之间有很好的一致性。显著的同时预测接受性语言的因素包括手势、非语言认知能力和对联合注意的反应。对于表现性语言，最显著的预测因素是非语言认知能力、手势和模仿。这些发现对针对这一人群的干预计划具有重要意义。
One of the primary diagnostic criteria for the diagnosis of autism spectrum disorders (ASD) is the presence of a language delay or impairment. Children with ASD are now being identified at significantly younger ages, and prior research has consistently found that early language skills in this population are heterogeneous and an important predictor for later outcome. The goal of this study was to systematically investigate language in toddlers with ASD and to identify early correlates of receptive and expressive language in this population. The study included 164 toddlers with ASD between the ages of 18 and 33 months who were evaluated on several cognitive, language and behavioral measures. Results suggested good agreement among different measures of early language, including direct assessment and parent report measures. Significant concurrent predictors of receptive language included gestures, non-verbal cognitive ability and response to joint attention. For expressive language, the most significant predictors were non-verbal cognitive ability, gestures and imitation. These findings have important implications for intervention programs targeting this population.
