Motivational interviewing (MI) is a clinical method designed to enhance personal motivation for change, not a comprehensive theory of change or a technique. It is not based on the transtheoretical model of change, nor is it a way of tricking people into doing what they don't want to do. MI is not a technique, decisional balance, assessment feedback, cognitive-behavior therapy, client-centered therapy, easy to learn, practice as usual, or a panacea. It is a collaborative, person-centered approach that emphasizes eliciting the client's own arguments for change, not imposing external ones. MI is not a simple or easy method, and it is not what clinicians are already doing without specific training. It is a complex skill that requires practice and understanding of its underlying principles. MI is not a one-size-fits-all solution and is not intended to address all situations. It is a specific tool for addressing behavior or lifestyle changes when individuals are reluctant or ambivalent. MI is not a panacea, and it is not a substitute for other treatment methods. It is a specific clinical method that requires clear understanding and application to ensure its effectiveness. The authors emphasize the importance of clarity about what MI is and is not to ensure quality assurance in research, clinical practice, and training.Motivational interviewing (MI) is a clinical method designed to enhance personal motivation for change, not a comprehensive theory of change or a technique.
