S. Thompson et E. Emerson, INTER-INFORMANT AGREEMENT ON THE MOTIVATION ASSESSMENT SCALE - ANOTHER FAILURE TO REPLICATE, Mental handicap research, 8(3), 1995, pp. 203-208
The present study evaluated inter-informant agreement on the Motivatio
n Assessment Scale across 42 topographies of challenging behaviour in
five children with severe intellectual disabilities. The results revea
led unacceptably low levels of inter-rater reliability on all sub-scal
es of the MAS and unacceptably low levels of inter-informant agreement
on the purported behavioural function of the rated challenging behavi
ours.
