The majority of previous research into restricted and repetitive behaviours (RRBs) has focussed on children, partly due to a lack of suitable measures for RRBs in adults. This study aimed to explore the psychometric properties of the Adult Repetitive Behaviour Questionnaire-2 (RBQ-2A) in a large sample of autistic adults using a self-report questionnaire method. The RBQ-2A and Autism-Spectrum Quotient (AQ) were administered online. Data from 275 autistic adults aged 18–66 (M = 36.56, SD = 12.24; 100 men and 171 women) were analysed using polychoric principal components analysis (PCA). Reliability and validity were assessed using Cronbach’s alpha and correlation analyses. PCA resulted in two components of the RBQ-2A, interpretable as repetitive sensory and motor behaviours (RSMB) and insistence on sameness (IS). Both components showed acceptable internal consistency (α = .70 and .81 respectively) and were significantly moderately correlated with scores on the AQ (rs = .25 and .42). Participants’ scores on IS were higher than their scores on RSMB. RSMB, but not IS, was negatively associated with age, particularly in older adults (≥ 50 years). There were no gender differences. The RBQ-2A is a reliable and valid self-report measure of RRBs in the present sample of autistic adults. As one of the few measures of RRBs aimed at adults, it is suitable for adults with the ability to read and complete a self-report questionnaire. Results build on previous work with children using the Repetitive Behaviour Questionnaire-2 (RBQ-2).

使用自闭症成年人中的成人重复性行为问卷2评估受限和重复性行为的亚型

先前有关限制性和重复性行为(RRB)的大多数研究都集中在儿童身上,部分原因是缺乏针对成人RRB的适当措施。这项研究旨在探讨使用自我报告调查表方法的大量自闭症成年人样本中的成人重复行为问卷2(RBQ-2A)的心理测量特性。RBQ-2A和自闭症频谱商(AQ)在线进行管理。使用多变量主成分分析(PCA)分析了275位年龄在18-66岁(M = 36.56,SD = 12.24; 100位男性和171位女性)的自闭症成年人的数据。使用Cronbach's alpha和相关性分析评估信度和效度。PCA产生了RBQ-2A的两个组成部分,可以解释为重复的感觉和运动行为(RSMB)和坚持相同性(IS)。两种成分均表现出可接受的内部一致性(分别为α= 0.70和.81),并且与AQ得分显着适度相关(rs = .25和.42)。参与者在IS上的得分高于他们在RSMB上的得分。RSMB(而非IS)与年龄呈负相关,尤其是在老年人(≥50岁)中。没有性别差异。RBQ-2A是目前自闭症成人样本中RRB的可靠且有效的自我报告指标。作为针对成年人的RRB的少数措施之一,它适合具有阅读能力并完成自我报告调查表的成年人。结果是基于先前使用重复性行为问卷2(RBQ-2)与儿童进行的工作而得出的。参与者在IS上的得分高于他们在RSMB上的得分。RSMB与年龄呈负相关,但与IS无关,尤其是在老年人(≥50岁)中。没有性别差异。RBQ-2A是目前自闭症成人样本中RRB的可靠且有效的自我报告指标。作为针对成年人的RRB的少数措施之一,它适合具有阅读能力并完成自我报告调查表的成年人。结果是基于先前使用重复性行为问卷2(RBQ-2)与儿童进行的工作而得出的。参与者在IS上的得分高于他们在RSMB上的得分。RSMB与年龄呈负相关,但与IS无关,尤其是在老年人(≥50岁)中。没有性别差异。RBQ-2A是目前自闭症成人样本中RRB的可靠且有效的自我报告指标。作为针对成年人的RRB的少数措施之一,它适合具有阅读能力并完成自我报告调查表的成年人。结果是基于先前使用重复性行为问卷2(RBQ-2)与儿童进行的工作而得出的。作为针对成年人的RRB的少数措施之一,它适合具有阅读能力并完成自我报告调查表的成年人。结果是基于先前使用重复性行为问卷2(RBQ-2)与儿童进行的工作而得出的。作为针对成年人的RRB的少数措施之一,它适合具有阅读能力并完成自我报告调查表的成年人。结果是基于先前使用重复性行为问卷2(RBQ-2)与儿童进行的工作而得出的。
