Motivational interviewing for addiction is a client-centered counseling approach that empowers individuals to overcome substance use by enhancing their intrinsic motivation to change. This non-confrontational method fosters a collaborative relationship between therapist and client, focusing on empathy, autonomy, and resolving ambivalence. Techniques like open-ended questions, affirmations, and reflective listening help clients explore their reasons for change, leading to improved treatment engagement and long-term recovery outcomes.
