Motivational Interviewing Techniques in Health Behavior Change
Summary
Motivational interviewing (MI) is a person-centred, directive counselling approach designed to elicit and strengthen intrinsic motivation for behaviour change. Grounded in principles of empathy, partnership and respect for autonomy, MI combines a relational foundation—often referred to as the “MI spirit”—with specific communication techniques. Practitioners employ Open questions, Affirmations, Reflective listening and Summaries (collectively known as OARS) to evoke “change talk,” the client’s own arguments for change, while minimising “sustain talk,” language that reinforces the status quo. MI is applied across diverse health domains, including substance misuse, weight management, chronic disease self-management and preventative screening, and is effective in brief and extended formats. Training typically involves didactic instruction, skills practice, feedback and fidelity monitoring to ensure adherence to MI principles. Global interest in MI reflects its adaptability to varied cultural contexts and delivery modes, from face-to-face consultations to digital platforms. By emphasising client choice and ambivalence resolution, MI offers a scalable framework for clinicians, public health practitioners and allied professionals seeking to support sustainable health behaviour change.
