Using self‐monitoring and differential reinforcement of low rates of behavior to decrease repetitive behaviors: A case study

We used a reversal design to evaluate the effects of a self‐monitoring system and differential reinforcement of low rates of behavior on decreasing repetitive body movements in a child with autism. A trial‐based functional analysis revealed that repetitive body movements were maintained by automatic reinforcement. Treatment consisted of teaching the participant to use a self‐monitoring system to monitor the occurrence of repetitive body movements. A stimulus control analysis revealed the self‐monitoring system acquired stimulus control over the repetitive body movements, in that they were more likely to occur in the absence of the system than in its presence. The self‐monitoring system was implemented with a differential reinforcement of low rates of behavior, and their combined effects were evaluated within a reversal design. Repetitive body movements decreased with the implementation of the treatment. The use of self‐monitoring systems to target problem behavior is discussed.
