Repetitive behaviours are an essential part of the diagnosis of autism but are also commonly seen in typically developing children. The current study investigated the frequency and factor structure of repetitive behaviours in a large community sample of 2-year-olds.
A new measure, the Repetitive Behaviour Questionnaire (RBQ-2) was completed by 679 parents.
The RBQ-2 had good psychometric properties. A four-factor model provided the best fit for the data, accounting for 51% of the variance, and suggested 4 sub-scales: unusual sensory interests, repetitive motor movements, rigidity/adherence to routine and preoccupations with restricted patterns of interest. These sub-scales closely resembled repetitive behaviour subtypes within the ICD-10 criteria for autism. Repetitive behaviours of every type were frequently reported. Higher scores were found for all children, and especially boys, on the subscale relating to preoccupations with restricted patterns of interests.
The results support the proposal that repetitive behaviours represent a continuum of functioning that extends to the typically developing child population.
重复行为是自闭症诊断的重要组成部分，但在发育正常的儿童中也很常见。本研究调查了一个大型2岁儿童社区样本中重复行为的频率和因素结构。
679名家长完成了一项新的测量工具——重复行为问卷（RBQ - 2）。
RBQ - 2具有良好的心理测量学特性。一个四因素模型最适合该数据，解释了51%的方差，并提出了4个分量表：异常的感官兴趣、重复的运动动作、僵化/坚持常规以及对受限兴趣模式的专注。这些分量表与ICD - 10自闭症标准中的重复行为亚型非常相似。每种类型的重复行为都经常被报告。在与对受限兴趣模式的专注相关的分量表上，所有儿童尤其是男孩得分更高。
结果支持了重复行为代表一种功能连续体的观点，这种连续体延伸到了发育正常的儿童群体。
