"Two Friends Spending Time Together": The Impact of Video Visual Scene Displays on Peer Social Interaction for Adolescents With Autism Spectrum Disorder.

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.

Personalized AAC Intervention to Increase Participation and Communication for a Young Adult with Down Syndrome.

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 two separate studies in two key community settings: An inclusive post-secondary education program (a single-case reversal ABAB design), and a community shopping activity (a non-experimental 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 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.

The Effects of Shared e-Book Reading With Dynamic Text and Speech Output on the Single-Word Reading Skills of Young Children With Developmental Disabilities.

Purpose This study investigated the use of a new software feature, namely, dynamic text with speech output, on the acquisition of single-word reading skills by six children with developmental disabilities during shared e-book reading experiences with six typically developing peers. Method A single-subject, multiple-probe design across participants was used to evaluate the effects of the software intervention. Six children with developmental delays were the primary focus for intervention, while six children with typical development participated as peer partners in intervention activities. e-Books were created with the new software feature, in which a child selects a picture from the e-book and the written word is presented dynamically and then spoken out. These e-books were then used in shared reading activities with dyads including a child with a disability and a peer with typical development. Participants engaged in the shared reading activity for an average of 13 sessions over a 6-week time period, an average of 65 min of intervention for each dyad. Results Participants with disabilities acquired an average of 73% of the words to which they were exposed, a gain of 4.3 words above the baseline average of 1.7 correct responses. The average effect size (Tau-U) was .94, evidence of a very large effect. Conclusion The results provide evidence that the use of e-books with the dynamic text and speech output feature during inclusive shared reading activities can be an effective and socially valid method to develop the single-word reading skills of young children with developmental disabilities.

Using AAC video visual scene displays to increase participation and communication within a volunteer activity for adolescents with complex communication needs.

Volunteer activities can provide opportunities to learn new skills, build social networks, and contribute to enhanced self-esteem. Volunteering also provides a positive contribution to society, and an opportunity to participate in activities that may differ from those in paid employment. People with severe disabilities and complex communication needs, however, may face significant barriers in participating and communicating in volunteer activities. A multiple-probe-across-participants, single-case experimental design was used to evaluate the effectiveness of videos with integrated visual scene displays (video VSDs). The video VSDs were presented using a tablet-based augmentative and alternative communication (AAC) app, as an intervention to increase the percent of steps completed independently within a volunteer activity. Participants were four adolescents with autism spectrum disorder or Down syndrome, all of whom had complex communication needs. Each participant met the mastery criterion for the activity - completion of the volunteer work activities and communication exchanges with co-volunteers - with the use of the video VSDs. The results provide preliminary evidence that video VSDs may be an effective assistive technology for individuals with severe disabilities and complex communication needs to increase participation in volunteer activities, both as an instructional support in learning new skills, and as an AAC technique to support interaction with others.

Effects of Peer Support Interventions on the Communication of Preschoolers with Autism Spectrum Disorder: A Systematic Review.

Many young children with autism spectrum disorders (ASDs) experience difficulty in the development of communication skills. Teaching peers to make use of communication support behaviors has been investigated as a strategy to increase communication for young children with ASD in early childhood settings. The purpose of this systematic review was to examine (1) the overall effects of peer support interventions on the communication of young children with ASD and (2) any possible moderating variables related to participant and intervention characteristics. The social support model was used as a framework for the study of intervention components. Eighteen single-case experimental design studies (48 children with ASD) met the inclusion criteria and were advanced to the full coding and analysis phase of the investigation. Descriptive analyses and effect size estimations using the improvement rate difference (IRD) metric were conducted. Overall, peer support interventions were found to be effective across a range of young children with ASD and intervention approaches. Evidence was also identified for the use of the social support model as a framework to guide the development of peer interventions in early childhood settings. The use of friendship groups, the selection of play materials based on the interests of the child with ASD, and the provision of augmentative and alternative communication appeared to be associated with positive communication outcomes.
