Association for Behavior Analysis International

This symposium includes four papers on the assesssment and treatment of problem behavior in individuals with Autism Spectrum Disorder without the use of extinction. The first presentation by Clelia Deltour describes the assessment and treatment of problem behavior during activity transitions using differential reinforcement of appropriate behavior without extinction. The second presentation by Zoe Newman will describe a comparison of positive and negative reinforcement of approrpiate requests in the treatment of problem behavior maintained by escape from social situations, without extinction. The third presentation by Rebecca Schulman will describe an evaluation of the effects of within activity choices on escape-maintained problem behavior, without the use of extinction. The fourth paper by Chelsea Fleck will describe the treatment of meal refusal by manipulation of meal preference and modified protective equipment. Dr. SungWoo Kahng will serve as discussant.

Children with autism often present with difficulties during transitions (Davis, 1987). It is therefore important to develop procedures for assessing and treating problem behavior during transitions. The purpose of the present study was to replicate McCord, Thomson, and Iwata (2001) by developing and conducting an assessment and intervention for the transition-related problem behavior of two participants with disabilities. Following some pre-assessment analyses, we conducted a functional analysis of problem behavior during transitions between activities. The results suggested that problem behavior occurred in transitions involving a worsening in activity preference, for example terminating a preferred or neutral activity and initiating a non-preferred activity. Finally, we examined the effectiveness of an intervention consisting of differential reinforcement of alternative behavior without extinction on the problem behavior occurring during the transitions identified as problematic. The results suggested that differential reinforcement of alternative behavior without extinction effectively decreased problem behavior in all targeted activity transitions. Future directions will be discussed. Interobserver Agreement (IOA) was collected for at least 30% of all trials and averaged over 90% for all scored responses.

Some individuals diagnosed with autism and related disabilities engage in dangerous behavior when presented with social demands. We compared the efficacy and social validity of differential positive and negative reinforcement in the treatment of problem behavior maintained by escape from social interactions. We conducted latency functional analyses of aggression in a 16-year-old male individual diagnosed with autism and Landau-Kleffner syndrome. The results of the initial analogue analysis were inconclusive, therefore we conducted a modified analysis that included a control and test for verbal attention and physical proximity. After determining aggression was maintained by social avoidance in the form of physical proximity, we compared the use of positive reinforcement (requests for food) and negative reinforcement (requests to be alone) using a reversal design. Results indicate both procedures were equally effective in reducing rates of problem behavior to zero without the use of extinction. Social validity was assessed through surveys of caregivers and the participant's preference, and caregivers were satisfied with the procedures and the results. Generalization of treatment effects was assessed by extending the procedures to caregivers using a multiple-baseline design, and effectiveness of treatment was replicated across all caregivers. Overall, subject was able to engage in appropriate social interactions in order to access functional and arbitrary reinforcers as an alternative to aggression.
