Youth with autism spectrum disorder (ASD) often display disruptive behavior and noncompliance. Disruptive behavior in youth with ASD may limit their participation in educational and therapeutic activities and impact family functioning. Several evidence-based interventions are available for typically developing children, such as Parent–Child Interaction Therapy (PCIT). The current study examined the comparative effectiveness of PCIT for youth with ASD and without ASD. Results indicate that PCIT significantly improves parent-reported disruptive behavior in children with ASD at levels comparable to children without ASD. Additionally, improvements in ASD-related symptoms were noted for youth with ASD. These findings support the use of PCIT for children with ASD and provide clinicians with an evidence-based tool to address disruptive behavior in a wide spectrum of presenting children.
