Since the initial publication of this classic text, motivational interviewing (MI) has been used by countless clinicians in diverse settings. Theory and methods have evolved apace, reflecting new knowledge on the process of behavior change, a growing body of outcome research, and the development of new applications within and beyond the addictions field. Including 25 nearly all-new chapters, this revised and expanded second edition now brings MI practitioners and trainees fully up to date. William R. Miller and Stephen Rollnick explain how to work through ambivalence to facilitate change, present detailed guidelines for using their approach with a variety of clinical populations, and reflect on the process of learning MI. Chapters contributed by other leading experts then address such special topics as MI and the stages-of-change model; using the approach with groups, couples, and adolescents; and applications to general medical care, health promotion, and criminal justice settings.
