This is a 6-hour virtual workshop designed to help professionals sustain and strengthen their use of Motivational Interviewing (MI) when supporting individuals with mental health, substance use, and/or medical challenges. MI is an evidence-based, collaborative, person-centered approach that helps individuals explore and strengthen their own motivation for change. Participants will learn and practice more complex OARS skills, apply additional MI strategies and tools, and develop skills for effectively responding to sustain talk and discord. The workshop will also introduce basic concepts related to MI fidelity and provide guidance on next steps for continued MI skill development.
