With the publication of the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition, autism spectrum disorders are defined by two symptom clusters (social communication and restricted/repetitive behaviors) instead of the current three clusters. The current study examined the structure of the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT). First, an exploratory factor analysis was replicated whose results were largely comparable to the previous findings. Then, confirmatory factor analyses compared a two and three factor structure for the BISCUIT. Measures of model fit supported both the two and three factor models relatively well. When directly compared, the three factor model was found to be preferred over the two factor model. Implications are discussed.
随着《精神疾病诊断与统计手册（第五版）》的出版，自闭症谱系障碍由两个症状群（社交沟通和受限/重复行为）来定义，而非当前的三个症状群。本研究考察了《自闭症特质婴幼儿筛查量表（BISCUIT）》的结构。首先，重复进行了探索性因素分析，其结果在很大程度上与之前的研究结果相当。然后，验证性因素分析比较了BISCUIT的二因素和三因素结构。模型拟合度指标对二因素模型和三因素模型的支持程度都相对较好。直接比较时，发现三因素模型优于二因素模型。文中讨论了相关意义。
