A considerable body of research has shown strong support for the usefulness of motivational interventions in initiating treatment and in reducing use of alcohol, cigarettes, and abused drugs.  This study examined the effectiveness of integrating Motivational Interviewing (MI) techniques into the initial contact and evaluation session for substance users entering outpatient treatment across five community-based treatment settings.  Clients were randomized to receive either the standard intake/evaluation session at each site, or an intake session in which MI techniques and strategies were integrated. 
CTN-0005 Study Protocol


Participants assigned to MI had significantly better retention -- a key component of success -- through the 28-day follow-up than those assigned to the standard intervention.  There were no significant effects of MI on substance use outcomes at either the 28-day or 84-day follow-up.  Results suggest that community-based clinicians can effectively implement MI when provided training and supervision, and that integrating MI techniques in the earliest phases of treatment may have positive effects on retention early in the course of treatment.
