한국판 섬망 평가 척도-98(K-DRS-98)의 표준화 연구 = A Validation Study for the Korean Version of Delirium Rating Scale-Revised-98 (K-DRS-98)

다국어 초록 (Multilingual Abstract)

Objective : This study was conducted to develop and to validate the Korean version of Delirium Rating Scale-Revised-98(K-DRS-98), which is a scale for diagnosing delirium and evaluating its severity.
Method : After developing the K-DRS-98, 102 patients were rated by it among 4 diagnostic groups, such as delirium (N=25), dementia (N=27), schizophrenia (N=25) and others (N=25). To test for reliability, K-DRS-98 was independently administered by two psychiatrist. To test for validity, Korean version of Mini-Mental State Examination (MMSE-K) and Clinical Global Impression (CGI) were administered simultaneously. Statistical analysis was done with SPSS window version 12 package and statistical significance was p<0.05.
Result : Intemal consistencies (Cronbach α) of two raters were 0.867 and 0.858, respectively. Inter-rater reliability (κ) was 0.893 for severity items of K-DRS-98 and κ value of diagnosis items was 0.969. In Delirium group, Pearson correlation Coefficients (r) of K-DRS-98 were -0.682 for MMSE-K and 0.667 for CGI. In comparison Delirium group with Others, ANOVA post hoc multiple comparison LSD was statistically significant (p<0.001). The cutoff score to diagnosis of delirium can be recommended 16 for seventy items and 21.5 for total score, respectively.
Conclusion : The K-DRS-98 was showed good reliability and validity for the assessment of delirium. The K-DRS-98 is an easy and useful tool for diagnosing delirium and assessing its severity.
