Motivational interviewing is an evidence-based approach to behavior change counseling.  Now in its 3^rd decade, MI has significantly altered the manner in which behavior change is discussed within the fields of addictive disorders, acute and chronic disease management, criminal justice, social services and the management of severe and enduring psychiatric disorders. During this workshop, both the relational and technical components of MI, using both didactic and experiential methods will be addressed. The relational component refers to the interpersonal foundation of collaboration, power-sharing, and the appreciation of ambivalence which appears necessary, if insufficient, for effective behavior change. The technical component, the preferential evocation and reinforcement of change talk, is a unique contribution of MI and, when integrated with the MI-spirited relationship, facilitates the initiation and persistence of change.  Practitioners will learn how to integrate the principles and techniques of MI into their everyday practices.
