The "Questions about Behavioral Function" with its five subscales ("Attention", "Escape", "Nonsocial", "Physical", and "Tangible") was…

We used the Stereotyped and Self-Injurious Movement…

"Research in Developmental Disabilities", 24, 391-404] by examining the convergent validity of the behavior problems…
