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).
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.
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.
We suggest a newly derived CARS2-ST cutoff score of 28.5 for screening ASD and providing early intervention.
本研究检验了《儿童孤独症评定量表第二版》（CARS - 2）与《孤独症诊断观察量表第二版》（ADOS - 2）在识别孤独症谱系障碍（ASD）方面的有效性。
共有237名儿童同时接受了CARS - 2和ADOS - 2测试。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曲线来确定基于ADOS - 2进行ASD诊断时CARS - 2（CARS2 - ST）的最佳标准版本临界值。
CARS2 - ST与ADOS - 2显著相关（r = 0.864，p < 0.001），证明了其同时效度。基于ADOS - 2，识别孤独症和孤独症谱系时CARS2 - ST的最佳临界值分别为30和28.5。
我们建议采用新得出的CARS2 - ST临界值28.5来筛查ASD并提供早期干预。
