The Eyberg Child Behavior Inventory (ECBI) is a parent rating scale widely used to assess disruptive behaviors in children and adolescents. The purpose of this study is to assess psychometric properties and conduct standardization of the Korean ECBI. The Korean version of the ECBI was administered to parents of 707 children between the ages 2 and 12 (grade 6) from five areas of South Korea. For Korean children, the means of Intensity and Problem Scale raw scores were 70.7 and 3.5, respectively, much lower than the US norms. Cronbach’s alpha was 0.93 for the Intensity Scale and 0.93 for the Problem Scale of the Korean ECBI, indicating high internal consistency. The test–retest reliability was 0.92 and 0.97 for the Intensity and Problem Scales (n = 66), respectively. Convergent validity was assessed and confirmed by comparing the ECBI and the Child Behavior Checklist (CBCL). The ECBI Intensity Scale score correlated with the total problem score (0.81), externalizing problem score (0.85), and internalizing problem score (0.50) of the CBCL. Both Intensity and Problem Scale scores were significantly different between typical children and children receiving counseling services (n = 88): t = −13.365, t = −11.215, both p = .001, respectively. The factor structure of the ECBI indicated eight factors. Results indicated that the Korean ECBI is psychometrically sound. Further study is recommended to explore and confirm factor structures of the Korean version of the ECBI.
