Efficacy and Social Validity of Peer Network Interventions for High School Students With Severe Disabilities.

This randomized controlled trial examined the efficacy of peer network interventions to improve the social connections of 47 high school students with severe disabilities. School staff invited, trained, and supported 192 peers without disabilities to participate in individualized social groups that met throughout one semester. Compared to adolescents in the "business-as-usual" control group (n = 48), students receiving peer networks gained significantly more new social contacts and friendships.

The role of supported joint engagement and parent utterances in language and social communication development in children with autism spectrum disorder.

This study examined associations between three parent–child engagement states and social communication, expressive language, and receptive language at 8 month follow-up, in 63 preschool-age children with autism spectrum disorder. We extend the literature on supported joint engagement by dividing this state into higher order (HSJE) and lower order types, with HSJE involving greater reciprocity in toy play. We also examined parents’ follow-in utterances that co-occurred with each state.
