Abstract

Objectives: This study examined the validity of the Childhood Autism Rating Scale, Second Edition (CARS-2) compared with the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) in identifying autism spectrum disorder (ASD).

Methods: A total of 237 children were tested using both the CARS-2 and ADOS-2. We examined the correlation using Pearson's correlation analysis. In addition, we used a receiver operating characteristic graph to determine the optimal standard version of the CARS-2 (CARS2-ST) cutoff score for ASD diagnosis using the ADOS-2.

Results: The concurrent validity of the CARS2-ST was demonstrated by a significant correlation with the ADOS-2 (r=0.864, p<0.001). The optimal CARS2-ST cutoff scores were 30 and 28.5 for identifying autism and autism spectrum, respectively, based on the ADOS-2.

Conclusion: We suggest a newly derived CARS2-ST cutoff score of 28.5 for screening ASD and providing early intervention.

CARS-2与ADOS-2在自闭症谱系障碍诊断中的验证研究:一个临界值的建议。

目的:比较《儿童自闭症评定量表第二版》(CARS-2)与《自闭症诊断观察量表第二版》(ADOS-2)在自闭症谱系障碍(ASD)诊断中的有效性。方法:采用CARS-2和ADOS-2对237例儿童进行检测。我们使用Pearson相关分析来检验相关性。此外，我们使用受试者工作特征图来确定使用ADOS-2进行ASD诊断的最佳标准版CARS-2 (CARS2-ST)截止评分。结果:CARS2-ST的并发效度与ADOS-2显著相关(r=0.864, p)。结论:我们建议新导出的CARS2-ST临界值为28.5分，用于筛查ASD并提供早期干预。
