| Abstract: Practitioners working in the field of Applied Behavior Analysis (ABA), play a vital role in meeting the needs of individuals with Autism Spectrum Disorders and other developmental disorders. Due to the lack of highly qualified practitioners required for providing Evidence-based Practices, particularly in rural areas, many individuals are not receiving adequate services. Practitioners should be trained to implement ABA-based interventions with high-fidelity. Online training utilising internet-based technology can provide staff training in a cost and time-effective way. The aim of this study was to systematically review the literature researching online ABA-based training. Intervention characteristics, outcomes, and research quality in 16 studies were analysed, and the gaps were explored. Results were favourable, with all studies reporting positive or mixed findings. Quality ratings were notably low, especially for the group design studies. Recommendations for future research are proposed in light of identified methodological flaws in online learning research. |
