Analysis and intervention with two topographies of challenging behavior exhibited by a young woman with autism

Abstract

A functional analysis was conducted with a young woman who engaged in both self-injury and aggression. Self-injury functioned to access preferred stimuli while aggression served an escape function. Intervention, a package consisting of gradually increasing the delay to reinforcement (access or escape), mand training, and extinction was effective for decreasing self-injury. However, this intervention was less effective in reducing aggression. A modification of the intervention, in which the gradual delay procedure was eliminated, resulted in reductions in aggression. The findings are discussed in the context of assessment and intervention selection with individuals who engage in multiple topographies of challenging behavior.
