Methods : Five evaluator assessed 54 elderly clients with CDT and Korean Verson of Mini Mental Screening Examination(MMSE-K) from October 11th to December 12th, 2010. The researcher analyzed inter-rater reliability, correlation between raters of CDT with Intraclass correlation coefficients, concurrent validity, CDT and MMSE-K with Pearson correlation coefficient, and discriminative validity, comparison mean scores of CDT between groups, more than MMSE-K score 23 and less with Independent sample t-test. Results : The score of CDT decreased according to aging and increased according to education year. But, the correlation coefficients was low. The inter-rater reliability and content validity was statistically significant(p<.01). Also, the construct validity was statistically significant(p<.01)Conclusion : The CDT can be applied to screen cognitive function of elderly people clinically as an alternative to MMSE-K.
