High Quality Content by WIKIPEDIA articles! Motivational interviewing (MI) refers to a counseling approach in part developed by clinical psychologists Professor William R Miller, Ph.D. and Professor Stephen Rollnick, Ph.D. The concept of motivational interviewing evolved from experience in the treatment of problem drinkers, and was first described by Miller (1983) in an article published in Behavioural Psychotherapy. These fundamental concepts and approaches were later elaborated by Miller and Rollnick (1991) in a more detailed description of clinical procedures. Motivational interviewing is a semi-directive, client-centered counseling style for eliciting behavior change by helping clients to explore and resolve ambivalence. Compared with non-directive counseling, it is more focused and goal-directed. Motivational Interviewing is a method that works on facilitating and engaging intrinsic motivation within the client in order to change behavior. The examination and resolution of ambivalence is a central purpose, and the counselor is intentionally directive in pursuing this goal.
