Introduction to the Special Issue on Exploring the Versatility of Motivational Interviewing.

Evidence indicates that motivation early in treatment is critical to treatment outcome, and motivational interviewing (MI) has addressed this finding by helping individuals work through ambivalence about change. Not only has it demonstrated improvements in treatment outcome across treatment populations and settings, it has been adapted with success into brief motivational interventions. This special issue explores the use of MI with populations at great risk for ambivalence in therapy, including college students violating campus policy, individuals who have been trafficked, and individuals in exposure therapy. The papers further highlight the versatility of MI-based interventions, as well as their limitations, that may help inform future directions for adapting MI as we move toward digital and web-based interventions.
