Parametric analysis of response interruption and redirection as treatment for stereotypy.

Response interruption and redirection (RIRD), a procedure in which demands are delivered contingent on stereotypy, has been shown to reduce vocal and motor stereotypy maintained by automatic reinforcement. However, RIRD can be time consuming and can interrupt ongoing activities and access to reinforcement for appropriate behavior. We attempted to address these limitations by comparing the effectiveness of RIRD using the standard 3-demand procedure to RIRD using just 1 demand. Results showed that RIRD with 1 demand was effective in reducing stereotypy for all participants, required fewer demands overall, and resulted in shorter implementation time. In addition, 2 participants showed an increase in appropriate play during RIRD. These results suggest RIRD with 1 demand may be an effective and less intrusive procedure for reducing stereotypy.
