Background: Autism is a neuro-developmental disorder that impresses on social interaction, verbal and nonverbal communication and stereotyped behavioral patterns. In this paper we tried to examine whether Pivotal response treatment(PRT) would be effective on adaptive behaviors.Materials & Method: The research method was quasi-experimental with case-control. Eleven children diagnosed with ASD according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) was selected. Adaptive Behavioral were evaluated with the Vineland test in two phases, before and after intervention (24 sessions). Findings: Results showed adaptive behaviors were improved after 3 months intervention (p < 0.05).Conclusion: PRT can improve adaptive behavioral problems, such as social skill, in children with ASD. The results of this study can provide a good approach to speech and language pathologists and all experts who are associated with these children.
