Abstract
Objective: The Community Screening Instrument for Dementia ( CSI-D) has been reported to be sensitive. The authors examined the reliability and validity of a Chinese ( Taiwanese) version of the CSI-D for elderly patients. Methods: Four groups were tested with the CSI-D: 31 with mild or moderate dementia; 32 non-dementia, depressed subjects; and 34 low- education, and 30 high-education normal -comparison subjects. Patients with dementia or depression were selected from outpatients of two hospitals. Testing was carried out in either the community or outpatient setting. Results: The internal consistency, interrater reliability, and test–retest reliability of the CSI-D were good. The CSI -D was highly correlated with scores on the Mini-Mental State Examination and 10-word- list-learning task. Correlation with the Montgomery-Asberg Depression Rating Scale was not significant. Receiver Operating Characteristic analysis suggested that the CSI-D was a good instrument in differentiating dementia from depression and normal subjects with low education. It had good sensitivity and specificity . Education was related to the cognitive scores but not related to informant scores. The combination of an informant interview with a cognitive test enhanced the performance of the CSI-D. Conclusions: The Taiwan Chinese version of the CSI-D is psychometrically sound, brief, easy to complete, and therefore suitable as a screening instrument for dementia in Taiwan. The study reinforces earlier suggestions that the informant interview yields improved validity for detecting dementia.
