This instructor-led course will provide an introduction to Motivational Interviewing (MI), a counseling style conceptualized by William R. Miller and Stephen Rollnick popularized by their 1991 book, Motivational interviewing: preparing people to change addictive behavior, which is now available in a second edition (2002). The course focus is on the foundational elements of MI and the spirit or counseling style that underlies its techniques. The Stages of Change, a separate yet compatible model of change, will also be explored. This course is introductory and geared toward people with no or little exposure to MI. The ATTC plans to develop a more advanced course to be offered in the future.
