The current study evaluated the use of Superheroes Social Skills to promote accurate use of discrete social skills in training and generalization conditions in two children with autism spectrum disorder. Participants attended a twice weekly social skills training group over 5 weeks, with lessons targeting nonverbal, requesting, responding, and conversation skills. A multiple probe across social skills design, replicated across participants, was utilized to assess the effects of participation of the intervention on skill accuracy. Following introduction of the intervention, participants demonstrated abrupt improvements in skill accuracy in both training and generalization conditions. Additionally, parental reports of participant social functioning indicated improvements following participation in the intervention. Limitations and future directions are discussed.
