Examining the effectiveness of a variable momentary differential reinforcement of other behavior procedure on reduction and maintenance of problem behavior

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this study, experimenters evaluated the effectiveness of variable momentary differential reinforcement of other behavior (VM DRO) schedules in the reduction and maintenance of problem behavior. Two individuals who had been diagnosed with developmental disabilities and autism spectrum disorder participated. Results of functional analyses indicated that problem behavior for both participants was maintained by social-positive reinforcement. VM DRO was effective at reducing one participant's problem behavior. Fixed interval differential reinforcement of other behavior (FI DRO) was effective at reducing the other participant's problem behavior, and VM DRO failed to maintain the results produced by the FI DRO procedure. These findings suggest that VM DRO may not be effective at reducing problem behavior for all individuals and that outcomes may be idiosyncratic. More evidence is needed to determine the effects of VM DRO as a maintenance procedure for other DRO procedures.
