Purpose <p>Social skill interventions are frequently used to support the development of social competence in children with autism spectrum disorder (ASD). The Superheroes Social Skills program (SSS), a multicomponent social skills curriculum, has shown promise in supporting social skill acquisition and use in autistic children. The present exploratory pilot study evaluated the effectiveness of a brief version of SSS on social skill accuracy and quality of skill use of five young children with ASD.</p> Method <p>Single-case design (multiple probe design across skills, replicated across participants) was used to evaluate the effect of a brief SSS intervention implemented in a series of weekly 20-minute sessions. Five young autistic children participated in the study. Social skill accuracy and quality of skill use were measured to assess the impact of the intervention.</p> Results <p>Results of the study indicated that participants increased in social skill accuracy and quality of skill use following participation in the intervention, with statistical analysis of data also supporting the effectiveness of the brief intervention.</p> Conclusion <p>Although preliminary, findings of this pilot study suggest that a brief variation of SSS may have utility as a strategy to address social skill needs in young children with ASD. Given the small sample included in the study, further replication is necessary to address limitations to external validity.</p>
