Embedding evidence-informed practices for children with mental health needs into “real-world” community settings has proven challenging. In this article, we discuss how the Practical, Robust, Implementation, and Sustainability Model (PRISM) guided statewide (New York) implementation of an evidence-informed intervention targeting families and youth with oppositional defiant and conduct disorders, collectively referred to as disruptive behavior disorders. Additionally, we present qualitative findings based on provider reports of integrating a novel, evidence-informed intervention within their respective community mental health settings. Finally, we discuss a process of modifying the intervention to address agency-level factors, as well as inform more widespread implementation efforts.
