Adolescents with autism spectrum disorder (ASD) often require support both for learning new skills and for communication. This study used a multiple baseline across activities design to evaluate the effect of videos with integrated visual scene displays (video VSDs), presented using a tablet-based app, on the percentage of steps completed independently within vocational training tasks by an adolescent with ASD and complex communication needs (CCN). Using the video VSDs, the participant met the mastery criterion for completing three tasks (including participation in communication exchanges) in a vocational setting. The results provide evidence that video VSDs may provide an effective support both for learning new skills in vocational contexts, and as a method of augmentative and alternative communication for individuals with ASD and CCN.

Purpose Social interaction poses many challenges for adolescents with autism spectrum disorder (ASD) and complex communication needs. The purpose of this study was to investigate the impact of video visual scene displays (video VSDs) on communication during interactions between adolescents with ASD and peer partners. Method This study used an across-participant multiple-baseline single-case experimental design. Four adolescents with ASD and complex communication needs were taught to use video VSDs, presented on a tablet-based app, during social interactions with peer partners in a high school setting. The video VSDs used during the interactions were selected (and programmed with vocabulary) based on the interests of the adolescent with ASD and their peer partner. Results Following the introduction of the video VSD intervention, all four adolescents with ASD demonstrated an increase in communicative turns compared to baseline (Tau- U = 1.0, 95% CI [0.56, 1]), and all four increased in modes of communication used. Increased use of speech also was observed for the three participants who made use of speech prior to the intervention. All participants with ASD (and their peer partners) expressed an interest in continued use of the video VSD app to support social interaction. Conclusion The use of video VSDs may be a viable option to increase the participation and communication of adolescents with ASD during social interactions with peer partners.

Many adults with Down syndrome (DS) experience difficulty with speech production, and intelligibility challenges and communication breakdowns are common. Augmentative and alternative communication (AAC) intervention can provide important supports for persons with these complex communication needs but must be customized to address the goals, strengths, and needs of the individual. This article provides a description of a personalized AAC intervention for a young adult with DS whose speech was frequently unintelligible. The AAC intervention made use of a video visual scene display (VSD) approach and was investigated in 2 separate studies in 2 key community settings: An inclusive post-secondary education program (a single-case reversal ABAB design), and a community shopping activity (a nonexperimental AB case study design). The participant demonstrated sharp increases in successful communication and participation in both settings following the introduction of the video VSD, and both the participant and the key stakeholders viewed the intervention positively. The results provide preliminary evidence that personalized AAC intervention, including the use of a video VSD approach, can provide important supports for communication and participation in community settings for adults with DS and complex communication needs.

Communicating with peers often poses challenges for individuals with autism spectrum disorder (ASD); these social interactions, however, can be especially difficult during the teenage years. For many adolescents with ASD, peer interaction is often limited or nonexistent, even for those taught in general education settings. The purpose of this meta-analysis was to investigate social interaction interventions for adolescents with ASD within public school settings, with a focus on studies that utilized single-case design. Studies were evaluated per the What Works Clearinghouse guidelines. This meta-analysis includes 24 studies with participants with ASD ranging in ages from 13 to 21 years. The effects of social skill interventions were evaluated using visual analysis, Tau- U, and a parametric effect size ( d-Hedges–Pustejovsky–Shadish [DHPS]). Combined effect sizes were calculated and compared. Results provide evidence that interventions can produce positive change in social behavior of adolescents with ASD. Effect sizes were generally large. Interpretations and implications are discussed.
