Validity and applicability of the Chinese version of community screening instrument for dementia.

The development of an educationally independent screening instrument for dementia is most valuable for epidemiological studies. The Community Screening Instrument for Dementia (CSI-D) was applied to 120 subjects, with 30 matched for age in each of the four groups of mild to moderately demented, depressed, low-education and high-education normal control subjects. The internal consistency and interrater reliability of CSI-D were satisfactory.
