“…In a multi‐cultural comparison study of the CBCL in preschool children, mean Total Problem Scores for Korean children ranked 4th from the bottom among 24 countries and lowest for DSM‐IV Oppositional Defiant Disorder [Rescorla et al, ]. Other studies have reported that Korean parents report fewer problems in their offspring on the CBCL‐internalizing and externalizing behavior scales than do parents from the US [Chung et al, ]or Australia [Oh, Shin, Moon, Hudson, & Rapee, ]. Since there is no evidence of prevalence differences between US and South Korea [Autism and Developmental Disabilities Monitoring Network Surveillance Year 2010 Principal Investigators, ; Kim et al, ; Zablotsky, Black, Maenner, Schieve, & Blumberg, ], observed discrepancies in the SRS raw scores between Korean and US children may reflect cultural differences in US and Korean parental reporting of their children's behaviors [Crijnen, Achenbach, & Verhulst, ]; that is, Korean parents may underreport their children's social problems compared to the parents in the US.…”
