Abstract

The purpose of this review was to assess the effectiveness of tablet-based speech-generating devices (SGDs) in improving communication skills for individuals with autism spectrum disorder (ASD). A total of 31 single-case design intervention studies involving 84 individuals with ASD were reviewed and included in the analysis. We calculated Tau-U to evaluate the impact of interventions involving tablet-based SGDs on four different communication responses: specifically, mands, intraverbals, tacts, and vocalizations. To explore potential moderating variables for mand outcomes, we used the Kruskal–Wallis one-way test. The analysis revealed that interventions utilizing tablet-based SGDs led to improvements in communication responses. Specifically, large to very large changes were observed in mand and intraverbal responses, whereas moderate changes were noted in tact responses and vocalizations. The findings of this review underscore the potential of tablet-based SGDs in enhancing communication among individuals with ASD. We discuss the findings and provide implications for future research and practice.
