Functional communication training and a chained schedule of reinforcement to reduce escape-maintained challenging behavior related to a daily routine

Children with autism spectrum disorder often exhibit challenging behavior to avoid exposure to common daily tasks or routines. There is a need to investigate methods to teach appropriate communication to replace challenging behavior and increase tolerance for daily routines. However, the data to support its use to decrease challenging behavior associated with an activity or routine is limited. In the present study, the authors evaluated the use of parent-implemented functional communication training (FCT) with a modified chained schedule of reinforcement to reduce challenging behavior associated with a nonpreferred daily routine. One 6-year-old male diagnosed with autism participated in this study. The functional analysis indicated that he engaged in challenging behavior to terminate throwing trash away. The authors then conducted a treatment evaluation to assess the efficacy of the FCT with a modified chained schedule of reinforcement in reducing challenging behavior and increasing the number of items that could be thrown in the trash. Results indicated that FCT with a modified chained schedule of reinforcement was effective in decreasing challenging behavior.
