abstract
Offering children with autism spectrum disorders (ASD) choices between activities (e. g., working on math or English), instructional materials (e. g., using a pen or pencil), or environmental arrangements (e. g., where to sit) has been shown to reduce challenging behavior maintained by escape from task demands. However, the majority of research investigating choice-based interventions for challenging behavior has examined across-activity choices (i. e., choosing between activities) and relatively few studies have examined within-activity choice (i. e., choosing between instructional materials or environmental arrangements). The purpose of this study is to replicate and extend previous research on choice-based challenging behavior interventions by comparing the effects of across-activity choices and within-activity choices on the escape-maintained challenging behavior of 4 children with ASD. An alternating treatment design was embedded within the "B" phase of an ABAB design in which the "A" phase represented a no-choice baseline condition. Both choice formats resulted in less challenging behavior than the baseline condition for all participants. Across-activity choice resulted in less challenging behavior than within-activity choice for 3 participants. Implications for research and practice are discussed. 2012 Springer Science+Business Media, LLC.
