目的：检验孤独症行为量表（ABC）的同时效度和效标效度。研究方法：三组，包括38名母亲的儿童以前诊断为自闭症（DSM IV-TR，2002年），43名母亲的儿童与语言障碍以外的自闭症，和52名母亲的儿童谁没有语言或行为的投诉，进行了采访。为了尽量减少母亲文化程度的影响，研究者完成了问卷，以确定同步验证，方差分析和判别分析。用ROC曲线确定样本的临界值，并检验效标效度。结果：孤独症儿童母亲组的总分显著高于其他组。ABC正确识别了81.6%的自闭症儿童。ROC曲线截断值为49，敏感性为92.1%，高于截断值68时的57.89%。特异性为92.6%，与临界值为68的94.73%相似。结论：ABC显示出作为一种工具来识别自闭症儿童的希望，无论是在临床还是教育背景下，特别是当使用49分的截止分数时。
Objective: To examine the concurrent and criterion validity of the Autism Behavior Checklist (ABC). Methods: Three groups, comprising 38 mothers of children previously diagnosed with autism (DSM IV-TR, 2002), 43 mothers of children with language disorders other than autism, and 52 mothers of children who had no linguistic or behavioral complaints, were interviewed. In order to minimize the effect of maternal level of education, the questionnaire was completed by the researcher To determine the concurrent validation, ANOVA and discriminant analysis were used. The ROC curve was used to establish the cutoff score of the sample and to examine the criterion validity. Results: The mean total score was significantly higher in the group of mothers of autistic children than in the other groups. The ABC correctly identified 81.6% of the autistic children. The ROC curve cutoff score was 49, and the sensitivity was 92.1%, higher than the 57.89% found when a cutoff score of 68 was used. The specificity was 92.6%, similar to the 94.73% obtained with a cutoff score of 68. Conclusions: The ABC shows promise as an instrument for identifying children with autistic disorders, both in clinical and educational contexts, especially when a cutoff score of 49 is used.
