This study examined the validity of the Korean version of the Child Behavior Checklist (K-CBCL) with 180 children with autism spectrum disorder (ASD) in South Korea. Rasch analysis was applied to examine item fit, item difficulty, suitability of the response scale, and person and item separation indices of the K-CBCL. The results indicated that, with the exception of six out of the 119 items, the K-CBCL had a good item fit. Suitability of the rating scale was supported. Both Attention Problems and Aggressive Behavior factors differentiated two strata of behavior problems of children with ASD, whereas six other factors only captured one stratum of behavior problems. The item separation index indicated that the items were distributed well with high reliability. We demonstrated that statistical item analysis with the Rasch model could provide valuable information related to psychometric properties.

本研究对韩国 180 名患有自闭症谱系障碍 (ASD) 的儿童进行了韩语版儿童行为检查表 (K-CBCL) 的有效性检查。应用 Rasch 分析来检查 K-CBCL 的项目适合度、项目难度、响应量表的适合度以及人和项目分离指数。结果表明，除了 119 个条目中的 6 个之外，K-CBCL 具有良好的条目拟合。支持评级量表的适用性。注意问题和攻击性行为因素都区分了 ASD 儿童行为问题的两个层次，而其他六个因素仅捕获了一个行为问题层次。题项分离指数表明题项分布良好，信度高。
