此前大多数关于限制性重复行为 (RRB) 的研究都集中在儿童身上，部分原因是缺乏针对成人 RRB 的合适措施。本研究旨在采用自我报告问卷法，探讨成人重复行为问卷 2 (RBQ-2A) 在大样本自闭症成人中的心理测量特性。 RBQ-2A 和自闭症谱商 (AQ) 是在线进行的。使用多向主成分分析 (PCA) 对 275 名 18-66 岁自闭症成人（M = 36.56，SD = 12.24；100 名男性和 171 名女性）的数据进行了分析。使用 Cronbach α 和相关分析评估可靠性和有效性。 PCA 产生了 RBQ-2A 的两个组成部分，可解释为重复的感觉和运动行为 (RSMB) 和坚持相同性 (IS)。两个成分均显示出可接受的内部一致性（分别为 α = .70 和 .81），并且与 AQ 得分显着中度相关（rs = .25 和 .42）。参与者在 IS 上的得分高于在 RSMB 上的得分。 RSMB（而非 IS）与年龄呈负相关，尤其是老年人（≥50 岁）。没有性别差异。 RBQ-2A 是对当前自闭症成人样本中 RRB 的可靠且有效的自我报告测量。作为少数针对成年人的 RRB 措施之一，它适合有能力阅读并完成自我报告问卷的成年人。结果建立在之前使用重复行为问卷 2 (RBQ-2) 对儿童进行的研究的基础上。
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).
