Peer interaction supports adolescents in developing communicative, emotional, and social competence. Social interaction, however, poses many challenges for adolescents with autism spectrum disorder (ASD) and complex communication needs. This study used a multiple-probe across participants design to assess the impact of an intervention using videos with integrated visual scene displays (video VSDs), presented on a tablet-based app, on the communication of four adolescents with ASD and complex communication needs and their peer partners. Following intervention, all four participants demonstrated an increase in communicative turns compared to baseline (Tau-U=1.0, 95% CI [0.56, 1]), and three of the four increased in modes of communication used (including use of natural speech). All participants with ASD (and their peer partners) expressed an interest in continued use of the video VSD app to support social interaction.
