Development of the Cambridge Contextual Reading Test for improving the estimation of premorbid verbal intelligence in older persons with dementia

Abstract

The CCRT is a valid measure of verbal ability for older persons. When accurate information about years of full-time education is available, prediction of verbal intelligence should be made combining CCRT with demographic variables. Otherwise, prediction should be made using CCRT alone. The CCRT may be used in preference to NART in neuropsychological batteries with older persons provided caution is exercised when language difficulties are indicated.
