本研究在一名可能患有广泛性发育障碍（PDD）的学龄前儿童样本中评估了改良的幼儿自闭症量表（M-CHAT）和社会沟通问卷（SCQ）的心理测量学特征。样本包括82名年龄在18至70个月之间的儿童（54名诊断为PDD，28名诊断为非PDD）。对56名18-48个月的儿童进行了M-CHAT评分分析，对65名30-70个月的儿童进行了SCQ评分分析。使用M-CHAT上任何三个项目的临界值并降低SCQ的临界值可获得最佳的灵敏度和特异性。两种仪器的诊断协议也进行了比较，在重叠的子样本的39名儿童年龄在30-48个月。总的来说，M-CHAT和SCQ似乎更准确地将智力和适应功能较低的PDD儿童分类。
This study assessed the psychometric properties of the Modified Checklist for Autism in Toddlers (M-CHAT) and the Social Communication Questionnaire (SCQ) in a sample of preschool children referred for possible pervasive developmental disorders (PDDs). The sample consisted of 82 children between the ages of 18 and 70 months (54 with a PDD diagnosis and 28 with non-PDD diagnoses). M-CHAT scores were analyzed for 56 children aged 18-48 months old and SCQ scores were analyzed for 65 children aged 30-70 months old. Optimal sensitivity and specificity were achieved using the cutoff score of any three items on the M-CHAT and lowering the cutoff score of the SCQ. The diagnostic agreement of both instruments was also compared in an overlapping subsample of 39 children aged 30-48 months. Overall, the M-CHAT and SCQ appear to more accurately classify children with PDDs who have lower intellectual and adaptive functioning.
