Efficacy of Centervention-ATOD: An Implementation Tool for Dissemination of Evidence-based Programs for Substance Abuse

Overview

The pilot test of Centervention-ATOD, a customizable suite of online tools specifically designed to support quality implementation and sustainability of any ATOD-EBP within real-world service settings, will evaluate whether the product awards additive benefits in provider implementation proficiency and efficacy, quality of implementation delivery, and EBP (i.e., Free Talk or CHOICE) outcomes compared to traditional implementation methods. Additionally, a cost-effectiveness study will be conducted to assess whether the implementation support strategy (i.e., Centervention-ATOD) is more cost-effective than traditional implementation methods.

Alcohol, tobacco, and other drug (ATOD) use among adolescents is a major public health problem with devastating personal, familial, and societal costs. Substance use in youth is associated with increased accidental injuries (including overdoses), psychiatric comorbidities, suicidality, school problems, juvenile delinquency, social and family problems, sexual impulsivity, and health consequences.A burgeoning neuroscience literature demonstrates ATOD use in youth is associated with a host of negative and potentially long-term sequelae, including alterations in brain structure, function, and neurocognition. Moreover, drug use in adolescence is the best predictor of abuse in adulthood; data published by the National Center on Addiction and Substance Abuse reveal that 90% of adults who meet substance dependence criteria began using alcohol and drugs during adolescence. In the U.S., the economic impact of substance abuse is staggering: in 2005, federal, state, and local governments spent a combined $467 billion on the direct and indirect costs associated with addiction, rendering substance dependence the largest, costliest, and most preventable public health problem in the U.S. today. Over the past few decades, significant progress has been made in the field of ATOD research in developing evidence-based practices (EBPs), with research demonstrating ATOD users who receive research-proven treatments are nearly 2.5 times more likely to achieve clinically significant post-treatment abstinence compared to those receiving non-evidence-based treatment. However, despite availability, EBPs are rarely adopted for use in everyday service settings. Further, even when adopted, considerable variation exists both in the quality with which EBPs are implemented and their long-term sustainability. Furthering our understanding of how efficacious treatment programs can be successfully introduced into real-world treatment settings is key to bridging this research-to-practice gap. The pilot test of Centervention-ATOD, a customizable suite of online tools specifically designed to support quality implementation and sustainability of any ATOD-EBP within real-world service settings, will evaluate whether the product awards additive benefits in provider implementation proficiency and efficacy, quality of implementation delivery, and EBP (i.e., Free Talk or CHOICE) outcomes compared to traditional implementation methods. Additionally, a cost-effectiveness study will be conducted to assess whether the implementation support strategy (i.e., Centervention-ATOD) is more cost-effective than traditional implementation methods. The pilot test will employ a Hybrid Type II study design\[14\] to simultaneously test the clinical evidence-based program as well as the implementation strategy. Regardless of the EBP implemented, 110 mental health (MH) providers will be randomly assigned to one of two conditions: (1) Enhanced implementation (EI) or (2) Implementation as Usual (IAU). Providers will either implement (a) Free Talk, a motivational interviewing group intervention with 5-8 youth per group over a six-week period or (b) CHOICE, a motivational interviewing group prevention program with 5-8 youth per group over a five-week period. Participating youth between ages 14-17 who may have experimented with alcohol or other drugs (AOD) will participate in the Free Talk intervention while youth between ages 11-15 who may or may not have used any substances will participate in the CHOICE prevention program. At the conclusion of the pilot test, a study of cost-effectiveness of the implementation support strategy (i.e., Centervention-ATOD) will be conducted with agency administrators of participating providers.
