背景：限制和重复行为（RRBs）是自闭症的核心特征。主要由儿童组成的因素分析研究为RRB的两个领域提供了证据：重复感觉运动（RSM）和坚持相同（IS）行为。本研究探讨了孤独症诊断访谈修订版（ADI-R）和重复行为量表修订版（RBS-R）在评估孤独症青少年和成人RRB亚型中的有效性。方法：样本包括293名参与者（法师= 19.89岁，SDage= 4.88岁），他们的RRB通过ADI-R、RBS-R照顾者报告或RBS-R自我报告进行评估。通过验证性因素分析（CFA）来评估每个工具的双因素结构的有效性。计算Cronbach’s alpha以评估子量表的可靠性。仪器分量表和非语言智商（NVIQ）和age.Results之间的相关性进行了检查：探索性相关性是温和的，并提供了弱证据，有利于实用的CFA的ADI-R。RBS-R照顾者和自我报告CFA和内部测试支持两因素RSM和IS模型测试。与以前的文献一致，NVIQ与RBS-R护理人员RSM子量表呈负相关，但与IS无显著相关性。RBS-R自我报告分量表与NVIQ均无显著相关性。在不同的工具中，RSM分量表之间存在相关性，但IS之间的相关性很小。结论：本研究为使用RBS-R护理人员和自我报告来测量自闭症青少年和成人的RSM和IS行为维度提供了初步支持。目前的数据不支持使用ADI-R评估老年人中的这些RRB亚型。鉴于本研究的样本限制，必须谨慎解释结论。需要更多的研究来了解患者报告和自我报告的RRB之间的差异。对自闭症青少年和成人的RRB的进一步研究，特别是在具有更多性别和种族/民族多样性的样本中，对于告知社区对成年期自闭症的理解和知识至关重要。然而，不能假定为评估儿童而设计的工具适用于老年人。因此，我们探讨了自闭症诊断访谈修订版（ADI-R）和重复行为量表修订版（RBS-R）问卷，用于评估儿童RRB的工具，是否可以用于评估青少年和成人。这些信息对于告知临床医生和研究人员评估老年人RRB的最佳方法非常重要。本研究的目的是什么本研究的目的是确定ADI-R和RBS-R是否适合评估自闭症成人的RRB。由于RRB是广泛的，我们专注于这些工具如何测量两类RRB：重复感觉运动（RSM）和坚持相同（IS）行为。响应空间模型包括诸如手拍打和排列对象之类的行为。IS包括对变化的消极反应和坚持特定例程等行为。研究支持ADI-R和RBS-R用于评估儿童的这些类别;然而，对它们在老年样本中的使用知之甚少。本研究旨在解决这一研究空白。研究人员做了什么我们使用现有的数据，从自闭症青少年和成人评估...
Background:Restricted and repetitive behaviors (RRBs) are core features of autism. Factor-analytic studies composed primarily of children have provided evidence for two domains of RRBs: Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. The present study explores the validity of the Autism Diagnostic Interview-Revised (ADI-R) and the Repetitive Behavior Scale-Revised (RBS-R) for assessing these RRB subtypes in autistic adolescents and adults.Methods:The sample included 293 participants (Mage= 19.89 years, SDage= 4.88 years) whose RRBs were assessed via ADI-R, RBS-R Caregiver Report or RBS-R Self-Report. Confirmatory factor analysis (CFA) was conducted to assess the validity of the two-factor structure for each instrument. Cronbach's alpha was computed to assess subscale reliability. Correlations were examined between instrument subscales and nonverbal intelligence quotient (NVIQ) and age.Results:Exploratory correlations were modest and provided weak evidence in favor of the utility of a CFA for the ADI-R. The RBS-R Caregiver and Self-Report CFA and internal consistencies supported the two-factor RSM and IS model tested. Consistent with previous literature, NVIQ was negatively correlated with the RBS-R Caregiver RSM subscale, but not meaningfully associated with IS. Neither RBS-R Self-Report subscale was meaningfully correlated with NVIQ. Across instruments, RSM subscales were correlated, but associations between IS were minimal.Conclusions:The present study provides initial support for the use of the RBS-R Caregiver and Self-Report to measure dimensions of RSM and IS behaviors in autistic adolescents and adults. The present data did not support the use of the ADI-R to assess these RRB subtypes in older individuals. Conclusions must be interpreted cautiously in light of the present study's sample limitations. Additional research is needed to understand differences in caregiver-reported and self-reported RRBs. Further research on RRBs in autistic adolescents and adults, particularly in samples with more gender and racial/ethnic diversity, is critical to inform community understanding and knowledge of autism in adulthood.Lay summaryWhy was this study doneRestricted and repetitive behaviors (RRBs) are features necessary for the diagnosis of autism spectrum disorder and are assessed at all ages. It cannot be assumed, however, that instruments designed for assessing children are appropriate for use with older individuals. Therefore, we explored whether the Autism Diagnostic Interview-Revised (ADI-R) and the Repetitive Behavior Scale-Revised (RBS-R) questionnaire, instruments used to evaluate RRBs in children, can be used to assess adolescents and adults. This information is important to inform clinicians and researchers about the best ways to assess RRBs in older individuals.What was the purpose of this studyThe purpose of this study was to determine if the ADI-R and RBS-R are appropriate to assess RRBs in autistic adults. Since RRBs are broad, we focused on how well these instruments measure two categories of RRBs: Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. RSM includes behaviors such as hand flapping and lining up objects. IS includes behaviors such as negative responses to change and adherence to specific routines. Research supports the ADI-R and RBS-R for assessing these categories in children; however, little is known about their use in older samples. This study aimed to address this research gap.What did the researchers doWe used existing data from autistic adolescent and adults assessed …
