摘要:	Background Delirium is commonly seen in patients in consultation-liaison psychiatry. Assessing delirium severity is important in clinical practice. The Delirium Rating Scale-Revised-98 (DRS-R-98) has been already established as a valid and reliable tool to achieve this goal. This study was aimed to evaluate the reliability and validity of the Chinese version of the DRS-R-98 (DRS-R-98-C) in Taiwan. Method We recruited 4 patient groups with delirium (n = 28), alcohol dependence (n = 9), dementia (n =11), and schizophrenia and bipolar disorder (n = 11) and evaluated them with DRS-R-98-C and Mini-Mental Status Examination (MMSE) by 2 psychiatrists at a single assessment session. Results The results showed that mean DRS-R-98-C total and severity scores in delirious patients were found significantly higher than those in other patient groups. Interrater reliability of the DRS-R-98-C between 2 raters was high, with intraclass correlation coefficient of .98 for severity scale and .99 for total scale. Internal consistency was high with a Cronbach's α coefficient of .85 and .86 for DRS-R-98-C severity and total scales. A significant inverse correlation was found between the DRS-R-98-C and the MMSE score (r = −0.63, P < .001) for either severity or total scale among 28 delirious patients. Area under the curve established by receiver operating characteristic analysis was .93 and .96 for severity and total scales, respectively. Optimal cutoff of total score was 15.5, with sensitivity of 89.3% and specificity of 96.8%. Conclusion The DRS-R-98-C is a valid and reliable measure of delirium severity and can be used clinically to monitor the course of illness when administered serially.
