Motivational Interviewing Fidelity Coding

Motivational interviewing fidelity coding measures how faithfully and skillfully a practitioner delivers motivational interviewing (MI), the collaborative, change-talk-oriented counseling style. The dominant system, the Motivational Interviewing Treatment Integrity (MITI) code developed by Theresa Moyers, William Miller, and colleagues, has trained raters listen to recorded sessions and produce global ratings of the clinician's MI spirit alongside counts of specific behaviors, which combine into summary indices benchmarked against competency thresholds — making it a worked example of practice-specific treatment fidelity.
