This scale consist of items relating to the "survival roles" proposed by the World Health Organisation (physical independence, mobility, social integration and language, occupation and orientaition) and may be completed by non-professional observers. The scales has highly acceptable interrater and the internal reliability and is able to differentiate different levels of dementia. Moreover, ECA is able to describe the wide individual variation in individual functioning which is evident to the clinician but cannot be appreciated by standard cognitive tests, which have a "floor effect" in severly demented populations. ECA scores correlate high with both the Mini-Mental State Examination and psychometric assessment of agnosia, visual retention, verbal fluency, object naming and receptive language. A linear regression model is used to demonstrates the independence of ECA scores from age, education, associated pathology and perceptual handicap. The potential usefulness of the scale for both clinical and epidemiological studies is discussed.
