Motivational Interviewing

By Dr. Thad Leffingwell


This course is designed to introduce participants to the fundamental principles and practice of Motivational Interviewing (MI).

Professionals of all types including those who work in mental health and substance use (e.g. psychologists, psychiatrists, counselors, case managers) and health care (e.g., physicians, PAs, nurses) settings will benefit from this course by being exposed to principles of MI, which is an evidence-based approach to bring about behavior change in clients or patients who may be ambivalent and resistant about making adaptive changes.

This course includes:

  • Video lectures (4 short lecture videos, approximately 39 minutes of content)
  • A video example of MI in a health care setting (14 minutes)
  • Required readings (3 academic peer reviewed articles, approximately 120 minutes)
  • A post test
  • A course evaluation 

Learning Objectives

At the end of this module, students should be able to:
  • Define Motivational Interviewing
  • Describe the style and spirit and fundamental strategies of MI
  • Distinguish an MI approach from non-MI strategies
