This case study evaluated the effects of differential reinforcement of other behavior (DRO) on scripting in a four year-old child with Autism Spectrum Disorder, Obsessive Compulsive Disorder and Celiac Disease. The overall goal was to show that DRO as the only independent variable could reduce scripting in a child with autism. A vibrator was set to vibrate every six minutes to indicate the end of each interval during intervention and the behavior was measured using a partial-interval time sampling method during the two hour in-home private Applied Behavior Analysis session over a two month period. An A-BC-C design demonstrated that DRO successfully decreased scripting behavior in the child with autism. A dependent paired samples t-test was used to compare the rates of scripting during the first three days of baseline and last three days of intervention. Results demonstrated a 29% decrease in scripting behavior. This result extends previous research that showed DRO, within a combined intervention, could be effective in decreasing scripting of adolescents with autism.
