Abstract

Dementia screening tests need to have acceptable sensitivity and specificity. The current study aimed to determine the cutoff point of the Persian Cognitive State Test (P-COST) and test its diagnostic accuracy. The study was conducted using the known-groups method. A purposive sample of 50 patients with dementia and 150 older adults without dementia was recruited in Kashan, Iran. The reference standard included clinical interviewing and findings of a computerized tomography scan. The P-COST was the in­dex test. Mean P-COST scores of the two groups differed significantly (p < 0.001). The P-COST is a sensitive and precise test for assessing cognitive state and thus can be used for dementia screening and monitor­ing of older adults� health. © SLACK Incorporated.
