In this study we analyzed the effects of a brushing protocol on stereotyped behavior of a young boy with autism. First, a functional analysis was conducted which showed that the participant's stereotypy was maintained by automatic reinforcement. Next, the Wilbarger Protocol, a brushing intervention, was implemented. An ABA design was implemented in which the participant was observed during four phases: (a) baseline, prior to the administration of the brushing protocol; (b) week 3 of implementation of the brushing protocol; (c) week 5 of implementation; and (d) 6 months after the discontinuation of the brushing protocol. Findings suggest that the brushing protocol had no marked affect on levels of stereotypy. (Contains 2 figures.)
