Sustained, widespread availability of evidence-based practices (EBPs) is essential to addressing the public health and societal impacts of adolescent substance use disorders (SUD), as recognized by the NIDA priority to investigate strategies for effective and sustainable implementation of EBPs. There remains a particularly significant need to identify effective financing strategies, which secure and direct financial resources to support essential activities for EBP implementation and sustainment, and overcome cost-related barriers to the availability of effective adolescent SUD treatments. This project will compare the effects of two SAMHSA grant mechanisms (i.e., financing strategies), which supported the adoption of an EBP for adolescent SUD through either organization-focused or state-focused granting of funds. The project will examine penetration of Adolescent Community Reinforcement Approach (A-CRA) among eligible clinicians (i.e., proportion certified with adequate fidelity) and clients (i.e., proportion receiving the treatment) at the end of SAMHSA funding and sustainment of the treatment model, using a 10-element composite measure of treatment delivery and supervision activities, up to 5 years post-funding.
