Abstract

Purpose: The purpose of this study was to translate and test reliability and validity of The Korean version of The Cornell Scale for Depression in Dementia (K-CSDD) used for assessing depression among impaired cognitive older adults. Methods: Original CSDD was translated into Korean and Linguistic contents were verified through back-translation procedures. The participants were 97 older adults reside in long-term care facilities. The participants were assessed using the Korean version of Mini-mental Status Examination (MMSE-K), The Korean version of the Hamilton Depression Rating Scale (K-HDRS), The short form of the Geriatric Depression Scale-Korean (SGDS-K), and K-CSDD. Results: In the reliability test, Cronbach’s ⍺ coefficient and test-retest reliabilities were .78 and .48, respectively. In concurrent validity of the K-CSDD, there were significant correlations between the K-CSDD and K-HDRS (r=.78, p˂.01). Factor analysis resulted in six factors accounting for 68.8% of the common variance. ROC curve analysis identified a cut-off score of 5 for the K-CSDD, where the sensitivity was 80.4% and the specificity was 89.0%. Conclusion: This study shows that K-CSDD is the reliable and valid scale for healthcare professionals to assess depression in cognitive impaired older adults in Korea.
