Operating Characteristics of Brief Screens for Dementia in a Multicultural Population.

Operating characteristics of seven screens for dementia were compared across various groups for 795 persons who had received a criterion diagnostic evaluation. Area under the curve (AUC), based on receiver operating characteristics, was compared between and within scales as an indication of their efficiency. Differences in AUC were only 5% across all the scales for the entire sample, but increased to 11% across sociocultural groups and scales and to 20% across education groups and scales.
