How effectively is a clinician using Motivational Interviewing (MI)? The Motivational Interviewing Treatment Integrity (MITI) Version 4.2.1 behavioral coding system provides answers to this question and helps us shape feedback for improved skillfulness. Participants will engage in learning through well-paced, immersive and highly interactive discussions, using written materials, videos, audio recordings, exercises, and multiple practice opportunities. Participants will also have multiple opportunities to develop coaching plans for a variety of scenarios and practice delivering coding and coaching feedback. This workshop is ideal for practitioners who want to elevate their MI skills to a new level, for evaluating and improving one’s own work or helping others become more skillful, and for supervising and coaching others effectively in MI practice.
