Validation of Korean version of The Cornell Scale for Depression in Dementia among Older Adults in Long-Term Care Facilities

Abstract

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 cutoff 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.

The effect of digital reminiscence therapy on people with dementia: a pilot randomized controlled trial

“…A higher score indicates more depressive symptoms. The Cronbach's α of the K-CSDD was 0.88 in a previous study [32] and was 0.76 at baseline in this study.…”

“…Depression The Cornell Scale for Depression in Dementia (CSDD) was developed as an observational scale to evaluate depression in PWD [31]. The Korean version of the CSDD [32] was used by the nursing staff at each daycare center. The K-CSDD consists of 19 items, with a total score ranging from 0 to 38.…”

The Comprehensive Factors Affecting the Sleep Quality in Family Caregivers of Patients with Dementia in the Community of South Korea

“…Cut-off points of depression are 8 points, where 0 to 7 points indicate normal, 8 to 12 points is mild depression, and more than 13 points is severe depression. The Cronbach's ⍺ of this instrument was .78 in Lee et al' study [14] and it was .872 in this study.…”

“…(3) Psychosocial characteristics ① Depression In this study, the Korean version of the Cornell Scale for Depression in Dementia (CSDD) was used to measure the depression level of PWD [13,14]. CSDD is a tool with 19 questions designed to assess depression symptoms.…”

Developing a Korean Version of the Scale for the Observation of Agitation in Persons with Dementia of Alzheimer-Type

“…CSDD was developed by Alexopoulos et al [19] in 1988 and modified as Korean version by Lee et al [20] in 2015. The K-CSDD [20] is a reliable and valid scale for measuring depression of dementia patients in long-term care facilities, and was used for convergence validity in this study. This scale consists of 19 items in five categories; the score for each question rages from 0 (absent) to 2 (severe), with a total score range of 0-38.…”
