Research Abstract	Callous Unemotional Traits (CU traits) have been adopted as one of the specified features under Conduct Disorder (CD) in DSM-5. CD is directly related to antisocial behaviors including delinquecy. If CU traits could be detected in early life stages, we could prevent children from antisocial behaviors including delinquency. I conducted national survey for screening CU traits among Japanese children and adolescents by using Japanese verion of Inventory of Callous Unemotional Traits (JICU). A total of 4088 students participated in this research. I found a certain level of reliability and validity of JICU. Setting 80 percentile scores of JICU as cut-off for CU traits, 795 students were condidered as having CU traits. I found there was no cultural differences between Japanese and Western children and adolescents, who present with CU traits. We could adopt Western evidence based practices to prevent Japanese children and adolscent with CU traits from antisocial behaviors in the future.
