Diversity of key consonants used in communication (DKCC) is a value-added predictor of expressive language growth in initially preverbal children with autism spectrum disorder (ASD). Studying the predictors of DKCC growth in young children with ASD might inform treatment of this under-studied aspect of prelinguistic development. Eighty-seven initially preverbal preschoolers with ASD and their parents were observed at five measurement periods. In this longitudinal correlational investigation, we found that child intentional communication acts and parent linguistic responses to child leads predicted DKCC growth, after controlling for two other predictors and two background variables. As predicted, receptive vocabulary mediated the association between the value-added predictors and endpoint DKCC.
沟通中使用的关键辅音多样性（DKCC）是自闭症谱系障碍（ASD）中最初处于语言前阶段儿童表达性语言发展的一个增值预测指标。研究ASD幼儿DKCC增长的预测因素可能会为这一语言前发展中研究不足的方面提供治疗依据。在五个测量阶段对87名最初处于语言前阶段的ASD学龄前儿童及其父母进行了观察。在这项纵向相关性调查中，我们发现，在控制了另外两个预测因素和两个背景变量后，儿童的有意沟通行为和父母对儿童引导的语言反应预测了DKCC的增长。正如预期的那样，接受性词汇介导了增值预测因素与终点DKCC之间的关联。
