Ritchie, K. & Ledesert, B. (1991). The Measurement of Incapacity in the Severly Demented Elderly: The
Validation of a Behavioural Assessment Scale. International Journal of Geriatric Psychiatry, 6, 217-226.

The Behavioural Assessment Scale assesses the intellectual functioning and adaptive behaviors in 
patients suffering from severe dementia.
