This study examined whether language skills and nonverbal cognitive skills were associated with clinician-observed restricted and repetitive behaviors (RRBs) in a sample of 115 children with autism spectrum disorders (ASD) at ages 2 and 3. By age 3, RRBs were significantly negatively correlated with receptive and expressive language, as well as nonverbal cognitive skills. Increases in receptive and expressive language from age 2 to 3 significantly predicted decreases in RRBs, controlling for age in months, time between visits, and gains in nonverbal cognitive skills. This study contributes to the limited research that has examined early patterns and predictors of RRBs in young children with ASD.
本研究调查了在 115 名年龄为 2 至 3 岁的自闭症谱系障碍（ASD）儿童样本中，语言技能和非语言认知技能是否与临床医生观察到的受限和重复行为（RRBs）有关。到 3 岁时，RRBs 与接受性和表达性语言以及非语言认知技能显著负相关。控制月龄、就诊间隔和非语言认知技能的提高，2 岁至 3 岁期间接受性和表达性语言的增加显著预测了 RRBs 的减少。本研究为研究 ASD 幼儿 RRBs 的早期模式和预测因素的有限研究做出了贡献。
