MET (Motivational Enhancement Treatment) To Improve Treatment Engagement and Outcome in Subjects Seeking Treatment for Substance Abuse

Motivational Enhancement Therapy cover

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 effect of a treatment approach called Motivational Enhancement Treatment (MET), which is a manual-based treatment based on the principles of Motivational Interviewing in comparison to counseling-as-usual (CAU). The MET counselor evokes a person's intrinsic desire and ability to change drug use behaviors, rather than imposing a directive "do this" approach.
