NIDA-CTN-0005

This study aims to evaluate the efficacy of Motivational Interview (MI) techniques, relative to a standard treatment intake interview at participating CTPs, in enhancing treatment engagement and retention as well as in reducing substance use. It will also evaluate the durability of MI relative to standard treatment at CTPs through a 3 month follow-up. Secondary aims of this study are to explore patient characteristics associated with outcome, to evaluate the ability of clinicians at the CTPs to learn and effectively implement MI techniques, and to conduct process analyses which will assess and evaluate multiple aspects of this treatment approach.
