Training in motivational interviewing: a systematic review.

Motivational interviewing (MI), an evidence-based counseling approach, has received much recognition from a wide variety of health care professionals. Because of the rising interest in MI, there is increasing demand for training in this counseling approach. The MI training community has answered this call and as a result placed much emphasis on studying the MI training process. The purpose of this article is to provide a systematic review of the published research on MI training. Our goal is to provide a consolidated account of MI trainings outlining the populations receiving training, methods used, and training outcomes. We also identify which aspects of the (W. R. Miller & T. B. Moyers, 2006) eight stages of learning MI each study addressed. Recommendations for advancing the MI training research are highlighted.
