Outline of Final Research Achievements	Focusing on The Cognitive scale for Down Syndrome (CS-DS) developed in the UK in 2016, we developed a Japanese version of the CS-DS in 2021. In this study, we will (1) expand the target age range to 10 years and older, and (2) verify the validity of the Japanese version of the CS-DS by comparing it with the IQ/MA of the Tanaka-Binet Intelligence Test V in order to confirm the accuracy of the Japanese version. As for (1), the criterion-related validity of the Japanese version of the CS-DS and the external rating scale is 0.738 for the correlation coefficient of 10 years and older, and it may be possible to use the Japanese version of the CS-DS by setting the conditions of the raters. (2) A tendency to correlate mental age with the Japanese version of the CS-DS was observed in those who needed to have their life age modified by the Tanaka-Binet Intelligence Test V

Academic Significance and Societal Importance of the Research Achievements	情報評価尺度である日本語版CS-DSの精度が向上すれば、これまで困難とされていた認知機能評価が必要となるダウン症者を対象とした介入研究の評価指標として使用できる可能性がある。また、個人の支援としても個別の認知機能の経時的変化をアセスメントできるツールとなりうる。併せて、ダウン症者と同様に認知機能評価が困難とされるIQが低く、知的重症度が高い知的障害者への応用ができれば、生活支援に有用なアセスメントツールとして活用できる可能性がある。
