Motivational interviewing (MI) is a form of empathic dialogue used to strengthen a person’s motivation and commitment to change by exploring reasons for and resolving ambivalence about change. MI is an internationally recognized evidence-based practice(EBP) intervention for alcohol and drug abuse, and a wide variety of other health problems. This guide, published by the National Institute of Corrections, demonstrates how MI could be used by educators and case managers at every point in the corrections setting, from intake to case planning, monitoring and sanctioning, final case termination, and transition.
