本研究旨在提供限制和重复行为维度评估(DAB)的初步验证。DAB是一种新的家长报告测量工具，旨在获取关键的限制和重复行为(RRB)子域的全部范围。方法从Spark(Simons Foundation Power Auism Research For Knowledge)研究匹配中招募1,892名患有自闭症谱系障碍(平均[SD]年龄=10.81[4.14]岁)的儿童和青少年的父母完成DAB、几种现有的RRB工具以及社交和沟通障碍和焦虑的测量。结果探索性亚样本中的探索性图形分析确定了与假设的RRB亚域一致的8个维度：重复感觉运动行为、坚持相同、受限兴趣、特殊兴趣、感觉敏感性、自残行为、强迫和强迫行为、重复语言。探索性结构方程模型在验证性样本中的验证性应用表明，所得到的因素结构与数据有较好的拟合。衍生因素具有良好的信度、收敛效度和发散效度，具有很强的重测稳定性，并与关键的人口学、认知学和临床相关呈现出明显的关联模式。结论考虑到RRB在自闭症谱系障碍中的重要性和临床影响，DARB将在各种研究和临床环境中发挥作用。强有力的初步证据表明，新的比例尺是全面的，涵盖了许多不同的RRB亚域，而不是任何现有工具同时捕捉到的。
ObjectiveThis study aimed to provide initial validation of the Dimensional Assessment of Restricted and Repetitive Behaviors (DARB), a new parent-report measure designed to capture the full range of key restricted and repetitive behaviors (RRB) subdomains.MethodParents of 1,892 children and adolescents with autism spectrum disorder (mean [SD] age = 10.81 [4.14] years) recruited from the SPARK (Simons Foundation Powering Autism Research for Knowledge) research match completed the DARB, several existing RRB instruments, and measures of social and communication impairments and anxiety. A subsample of 450 parents completed the DARB after 2 weeks to evaluate the test-retest stability.ResultsExploratory graph analysis conducted in the exploratory subsample identified 8 dimensions that were aligned with hypothesized RRB subdomains: repetitive sensory motor behaviors, insistence on sameness, restricted interests, unusual interests, sensory sensitivity, self-injurious behaviors, obsessions and compulsive behaviors, and repetitive language. The confirmatory application of the exploratory structural equation modeling conducted in the confirmatory subsample showed that the derived factor structure had a good fit to the data. Derived factors had excellent reliability, convergent and divergent validity, and very strong test-retest stability and showed a distinct pattern of associations with key demographic, cognitive and clinical correlates.ConclusionThe DARB will be useful in a variety of research and clinical contexts considering the prominence and clinical impact of RRB in autism spectrum disorder. Strong preliminary evidence indicates that the new scale is comprehensive and captures a wide range of distinct RRB subdomains not simultaneously captured by any of the existing instruments.
