This article presents a literature review related to therapies or interventions used to improve social competence of children with autism spectrum disorder (ASD). Children with autism disorder have problems in their social environment where children cannot communicate or interact socially. This study reviews 20 international journals covering interventions used by involving parents, interventions involving peers, analysis of both methods, and conclusions. The interventions or therapies used vary, with the therapeutic setting taking place at home, at school, or at the place of professional therapy by involving parents and peers in the intervention. The design used in this research were single experiments and group experiments. The results of this literature review indicate that interventions that involve peers are more effective than interventions that involve parents in increasing the social competence of children with autism spectrum disorder because in peer intervention, they are directly involved. This research also influences further research, especially those conducted in Indonesia.
