The Autism Spectrum Quotient (AQ) has been widely used for measuring autistic traits however its factor structure has been primarily determined from nonclinic populations. This study aimed to establish an internally coherent and reliable factor structure for the AQ using a sample of 455 Australian adults of whom 141 had autism spectrum disorder (ASD) diagnoses. Principal component analysis revealed a 39-item questionnaire with five-factors: Sociability, Social Cognition, Interest in Patterns, Narrow Focus and Resistance to Change. The revised AQ-39 had sound goodness-of-fit indices, good-to-excellent internal consistency and test-retest reliability, and scores for ASD and non-ASD participants were significantly different. The AQ-39 may be useful in screening and for guiding the focus of therapy.
自闭症谱系商数（AQ）被广泛用于测量自闭症特征，但它的因子结构主要是从非临床人群中确定的。本研究旨在使用 455 名澳大利亚成年人的样本建立 AQ 的内部一致和可靠的因子结构，其中 141 人患有自闭症谱系障碍（ASD）诊断。主成分分析显示，一个由 39 个项目组成的问卷有五个因子：社交能力、社会认知、模式兴趣、狭隘关注和抗拒变化。修订后的 AQ-39 具有良好的拟合优度指数、良好到优秀的内部一致性和重测信度，ASD 和非 ASD 参与者的得分有显著差异。AQ-39 可能有助于筛选和指导治疗重点。
