Recognizing early risk markers in young children with autism spectrum disorder (ASD) is critical for timely diagnosis and intervention. The purpose of this study was to extend previous findings regarding language milestones to a longitudinal design, in which ages of expressive language milestones (i.e., first words, first phrases) could serve as predictors of developmental trajectories in a heterogeneous sample of young children with ASD (N = 98; age at first assessment: M = 32 months, SD = 5). Age of first words predicted trajectories of expressive language and adaptive skills; number of words predicted each outcome examined. Because these aspects of early language show promise as potential indicators of later functional outcomes, future research on developmental processes as they relate to individual differences will be particularly informative.
识别自闭症谱系障碍（ASD）幼儿的早期风险标志物对于及时诊断和干预至关重要。本研究的目的是将先前关于语言里程碑的研究结果扩展到纵向设计中，在该设计中，表达性语言里程碑的年龄（即第一个单词、第一个短语）可以作为ASD异质幼儿样本（N = 98；首次评估年龄：M = 32个月，SD = 5）发育轨迹的预测指标。第一个单词的年龄预测了表达性语言和适应技能的轨迹；单词数量预测了所检查的每个结果。由于早期语言的这些方面有望成为后期功能结果的潜在指标，因此未来关于与个体差异相关的发育过程的研究将特别具有参考价值。
