“Motivational interviewing is a collaborative, person-centered form of guiding to elicit and strengthen motivation for change.” Rollnick & Miller  It is not so much a stand alone form of psychotherapy as much as it is a communication approach that elicits behavior change by helping clients explore and resolve ambivalence. Over the years, MI has been shown to be an effective approach for helping people change behaviors. I periodically combine elements of the Transtheoretical Model of Change (TTM) or "Stages of Change" when using MI.
