Questions have been raised about the significance of restricted and repetitive behaviors (RRBs) in predicting outcomes of children with Autism Spectrum Disorders (ASDs). Previous studies have yielded mixed findings, but some suggest that the presence of RRBs during preschool years is a negative prognostic indicator for later childhood. This study examined the effect of RRBs at ages 1-2 and 3-5 years on cognitive functioning, adaptive abilities, and ASD symptomatology at age 8-10 years in 40 children with ASDs. At 1-2 years, RRBs did not predict later functioning. However, at 3-5 years, more severe preoccupations with parts of objects, sensory interests, and stereotyped motor movements predicted less developed cognitive and adaptive skills, and greater ASD symptom severity at age 8-10 years.
关于限制性行为和重复行为（RRBs）在预测自闭症谱系障碍（ASD）儿童预后方面的意义，人们提出了一些问题。以往的研究结果不一，但一些研究表明，学龄前出现RRBs是儿童后期预后不良的指标。本研究调查了40名ASD儿童在1 - 2岁和3 - 5岁时RRBs对其8 - 10岁时认知功能、适应能力和ASD症状的影响。在1 - 2岁时，RRBs并不能预测后期的功能。然而，在3 - 5岁时，对物体部分的过度关注、感官兴趣和刻板运动行为越严重，预示着8 - 10岁时认知和适应技能发展较差，ASD症状更严重。
