The reliability and validity of two assessment scales in the elderly mentally handicapped
AH Smith, BR Ballinger and AS Presly
The Clifton Assessment Schedule and the Shortened Stockton Rating Scale
were administered to 38 elderly, mentally handicapped patients. Inter-
rater reliability was high and the CAS was found to be a useful measure of
cognitive ability. The tests measure different features of patients, but
both correlated significantly with estimated levels of independence.
