This document provides an overview of motivational interviewing (MI), a collaborative communication style used to strengthen personal motivation for change. MI was originally developed to help with addiction and chronic disease management. The ultimate goal of MI is to allow for an honest discussion that helps clients experience and resolve ambivalence about behavior change. Key aspects of MI include using open-ended questions, affirming responses, reflecting questions, and summarizing to elicit a client's own reasons for change in a supportive environment. MI aims to create cognitive dissonance that provides a tipping point toward implementing and maintaining change goals. The document also discusses techniques for eliciting and supporting change talk and behavior.
