PURPOSE
The aim of this study was to investigate several possible factor structures of the Autism Spectrum Screening Questionnaire (ASSQ).
MATERIALS AND METHODS
We used the 27-item screening tool for school-aged children in a general population of 8-year-old children ( = 3,538) and compared the occurring solutions to previously published factor models.
RESULTS
A one-factor solution and a four-factor solution were identified in Exploratory Factor Analysis (EFA) and confirmed with Confirmatory Factor Analysis (CFA), while two-, three-, five- and six-factor solutions were rejected. In CFA, our four-factor solution showed the best goodness-of-fit indexes when compared with factor models previously presented by Posserud et al. and Ehlers et al.
CONCLUSIONS
The results indicate a strong underlying connection between all ASSQ items which is elicited by the one-factor solution. Although as a screening tool, ASSQ is functioning with the unifactorial solution, the four factors can help to identify certain clusters of autism spectrum traits.
目的
本研究旨在探讨自闭症谱系筛查问卷（ASSQ）的几种可能的因子结构。
材料和方法
我们使用 27 项针对 8 岁儿童的一般人群的筛查工具（ = 3538），并将出现的解决方案与之前发表的因子模型进行比较。
结果
探索性因子分析（EFA）确定了一个单因子解和一个四因子解，并通过验证性因子分析（CFA）得到了确认，而二、三、五和六因子解则被拒绝。在 CFA 中，与 Posserud 等人和 Ehlers 等人之前提出的因子模型相比，我们的四因子解显示出最佳的拟合优度指标。
结论
结果表明，所有 ASSQ 项目之间存在很强的内在联系，这是由单因子解引起的。虽然作为一种筛查工具，ASSQ 采用的是单因子解决方案，但四个因子可以帮助识别自闭症谱系特征的某些聚类。
