BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements the Behavioural Assessment Scale as described in:

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.

(Language - 5 questions, 
Social Integration - 5 questions, 
Occupation & Orientation - 3 questions, 
Physical Independence - 16 questions,

A total score (expressions.BAS_score) is calculated at the end.
