Zusammenfassung:Using the Japanese version of school form of the ADHD-RS, this survey attempted to compare the scores between the US and Japan and examined the correlates of ADHD-RS. The classroom teachers of 7414 children (3842 males and 3572 females) evaluated all the children's behaviors. A confirmed factor analysis of ADHD-RS confirmed the two-factor solution (Inattentive and Hyperactive-Impulsive) same as previous studies. ADHD-RS scores were not related to IQ, but were associated with standardized achievement test scores. Males showed stronger ADHD tendencies than did the females, and the males tended to score lower as they grew older. Our comparison of the scores between the US and Japan found the Japanese children scored lower than did their US children. Japanese version of school form of the ADHD-RS with good reliability and validity was developed. More researches of ADHD in Japanese children are required.
