title: The psychometric properties of the clock drawing test in South Korea.
abstract: [Purpose] The aims of the present study were to analyze the validity and reliability of the Clock Drawing Test (CDT) as a screening tool for cognitive impairments in both stroke patients and older adults in South Korea. [Subjects and Methods] Forty-three stroke patients and 42 elderly residents living in urban communities were recruited. They were divided into three groups according to K-MMSE scores. Kruskal-Wallis one-way ANOVA was used for construct validity, Friedman two-way ANOVA for discriminative validity, and Spearman's rank order correlation coefficient for inter-rater reliability. [Results] Regardless of groups, construct and discriminative validity tests showed statistically significant results, and Spearman's rho was over 0.56. [Discussion] CDT demonstrated acceptable validity and reliability. CDT using the productive methods and Freedman's scoring systems may be suitable for cognitive decrease in stroke patients and the elderly.
