Evaluating the dissemination of evidence-based practices in substance use treatment: A cluster-randomized clinical trial of Colombo Plan's Innovative professional training model

The training of professionals who work in the treatment of substance use disorders is a fundamental aspect for the dissemination of evidence-based practices that ensure the quality of the treatment delivered to patients. Colombo Plan has developed a training model that allows effective, rapid, and scalable dissemination. However, this model does not have an empirical evaluation of its results to date. This project seeks to evaluate the dissemination model through a cluster-randomized clinical trial with a parallel superiority design, in which 27 treatment centers will be randomly assigned to training + action plan and technical advice, training only, or control without training, action plan or advice. The results of this study will inform public policy regarding substance use treatment at the national level and will help improve efforts by Colombo Plan at dissemination of evidence-based practices.
