High-Probability Request Sequence: An Evidence-Based Practice for Individuals with Autism Spectrum Disorder

Wong et al. (2014) conducted a comprehensive review of the literature published between 1990 and 2011 to identify practices for children, adolescences, and young adults diagnosed with autism spectrum disorders (ASD) that had sufficient empirical support to be considered evidence-based. Behavior momentum interventions (BMI), or high-probability request sequence, was identified as a focused intervention practice with some support due to an insufficient number of participants. The purpose of this review was to expand on these findings from Wong et al. (2014) to determine if high-probability request sequence interventions can be considered an evidence-based practice for individuals with ASD. Results indicated the intervention can be considered an EBP for individuals with ASD. Implications for practice and suggestions for future research are discussed.
