The Autism Impact Measure (AIM) was designed to track incremental change in frequency and impact of core ASD symptoms. The current study examined the structural and convergent validity of the AIM in a large sample of children with ASD. The results of a series of exploratory and confirmatory factor analyses yielded a final model with five theoretically and empirically meaningful subdomains: Repetitive Behavior, Atypical Behavior, Communication, Social Reciprocity, and Peer Interaction. The final model showed very good fit both overall and for each of the five factors, indicating excellent structural validity. AIM subdomain scores were significantly correlated with measures of similar constructs across all five domains. The results provide further support for the psychometric properties of the AIM.
自闭症影响量表（AIM）旨在追踪核心自闭症症状的频率和影响的变化。本研究在一个大型自闭症儿童样本中检验了 AIM 的结构和收敛有效性。一系列探索性和验证性因素分析的结果得出了一个最终模型，该模型有五个具有理论和经验意义的子领域：重复行为、异常行为、沟通、社会互惠和同伴互动。最终模型在整体上和五个因素中的每一个因素上都表现出非常好的拟合度，表明其具有极好的结构有效性。AIM 子领域的分数与所有五个领域的相似结构的测量值显著相关。研究结果为 AIM 的心理测量特性提供了进一步的支持。
