Pivotal response treatment and applied behavior analysis interventions for autism spectrum disorder delivered by human vs robotic agents: a systematic review of literature.

Robotic technology-aided instruction and interventions have been designed to support both Applied Behavior Analysis (ABA) and Pivotal Response Treatment (PRT) interventions for children with ASD. However, to the best of our knowledge, this field has not been systematically reviewed. Thus, we aimed to systematically review the literature to determine whether ABA or PRT methods in a robotic therapeutic context yield better outcomes for individuals with ASD, specifically in terms of approaching and accepting robots. A comprehensive search of electronic databases including PubMed, EMBASE, and Google Scholar was conducted. Randomized control trials (RCT) and pre-post-test design investigations that assessed the impact of ABA vs. PRT approach via robot-mediated technology vs. human trainers on intervention outcomes of children with ASD were selected and included in this systematic review. Finally, 13 papers met the criteria for inclusion in the systematic review. Two independent reviewers extracted the associated data from each selected study according to the standardized data extraction form. Two reviewers also assessed the quality of each study independently using the Cochrane Back Review Scale and JBI tool for quasi-experimental studies. We categorized two general classifications of findings including ABA vs. PRT as well as robotic technology vs. human. In conclusion, the existing investigations on the effect of robotic assistive technology using ABA or PRT approach are promising particularly in therapeutic contexts with a more natural context and social flavor.
