Numerous studies have demonstrated the efficacy of response interruption and redirection (RIRD) for reducing vocal stereotypy in children with autism. However, the procedure can be time-consuming to implement. Results of Saini, Gregory, Uran, and Fantetti (2015) suggested that an abbreviated variation of RIRD was just as effective as the commonly used variation of RIRD, but further research is needed. In addition, no studies have evaluated the role of toy removal on the efficacy of RIRD even though this procedural component is frequently combined with RIRD. We examined the separate and combined effects of RIRD and contingent toy removal when three children with autism were required to respond to one demand versus three demands. One-demand RIRD was effective for all participants, and the contingent removal of toys alone reduced responding for two of three participants. Findings have important implications for treating vocal stereotypy in relevant settings.
