Evaluating the Utility of Commercial Videotapes for Teaching Hand Washing to Children With Autism

We evaluated the effects of using a commercially available video model to teach three preschoolers with autism to wash their hands. While one child learned 80% of the hand washing steps, 2 of the 3 children did not learn from the commercial model. All were subsequently exposed to a customized video model, which resulted in at least some acquisition of the skill for the two students who did not learn from the commercial model.
