Motivational interviewing is a collaborative counseling approach used to help clients who are ambivalent about changing problematic behaviors such as substance use. It involves using reflective listening, open-ended questions, affirmations and summaries to understand the client's perspective and strengthen their intrinsic motivation for positive change. The goal of MI is not to confront or argue with clients, but rather to reduce resistance and discord within the counseling relationship in order to facilitate movement through the stages of change.
