在一大群患有ASD的儿童，青少年和成人中检查了限制性重复行为（RRB），以描述与年龄相关的症状变化模式以及与特定背景因素的关联，并检查各种类型的RRB的变化模式是否不同。超过700名ASD患者被评为重复行为量表修订版。RRB在老年人中的发生频率和严重程度低于年轻人，这证实了自闭症症状随着年龄的增长而减轻。我们的研究结果进一步表明，重复行为是一组异质性的行为，RRB的亚型在整个生命周期中都有自己的个体模式，在某些情况下，与年龄的差异性关联取决于智力功能。
Restricted repetitive behaviors (RRBs) were examined in a large group of children, adolescents and adults with ASD in order to describe age-related patterns of symptom change and association with specific contextual factors, and to examine if the patterns of change are different for the various types of RRBs. Over 700 individuals with ASD were rated on the Repetitive Behavior Scale-Revised. RRBs were less frequent and less severe among older than younger individuals, corroborating that autism symptoms abate with age. Our findings further suggest that repetitive behaviors are a heterogeneous group of behaviors, with the subtypes of RRBs having their own individual patterns across the lifespan, and in some cases, a differential association with age depending on intellectual functioning.
