Abstract

The aim of the current study was to test the properties of a scale especially developed for use in epidemiological surveys in low sociocultural populations, and to determine whether this scale can be used in a clinical population. Material and Methods: Two hundred fifty subjects took part; 150 were controls and 100 had dementia of various types according to DSM-IV and NINCDS-ADRDA criteria. Results: Cronbach's alpha was equal to .78. In the group of people under 75 years old, sensitivity did not exceed 90%. Specificity was over 90% at the level 4/5. The respective scores for the group of people over 74 were 6/7 and 3/4. Discussion: The Epidemiological Dementia Index seems to be less powerful when used in a clinical population. This provides further evidence that it is not suitable to use the same instruments in both epidemiological studies and clinical practice.
