This guide explains how to implement motivational interviewing (MI) in correctional settings. Motivational Interviewing is a counseling technique that enables people to get beyond their reluctance to change problem behaviors. MI is directive (focused on goals), client-centered, and non-confrontational. The first four chapters of this guide \“address background and fundamental issues related to agency or systemwide implementation of MI … [while the last two chapters] address agency issues, such as organizational norms, mental models, and leadership styles that can significantly affect the success of MI implementation\” (p. 5). These chapters are: what MI is; how MI is learned; supervising and coaching to support implementation; assessing motivational interviewing skills; and planning to help individuals develop MI skills in a correctional setting. A glossary is also included.
