Abstract
The literature suggests that adolescents with ASD typically are not socially engaged during unstructured school activities and do not initiate social activities with typically developing peers. This study assessed whether implementing socialization opportunities in the form of lunch clubs based around aspects of the adolescents with ASD's perseverative interests would promote positive direct and generalized social interaction between the target adolescent and their typically developing peers. A repeated measures multiple baseline experimental design (with two reversals) was implemented across participants. During baseline measures, the participants did not show social engagement or initiations. During intervention, results showed large increases in both social engagement and initiations. Generalization measures also showed that the target adolescents improved their social engagements and initiations with typically developing peers throughout unstructured lunchtime activities. These results have implications for understanding variables related to social development in autism.
