Motivational Interviewing Techniques and Applications

Core Principles and Techniques

The American Academy of Pediatrics recommends motivational interviewing for improving oral health behaviors in children, with evidence showing reduction in severe caries in some populations and increased parent/caregiver knowledge 5
Motivational interviewing is a patient-centered counseling method that increases intrinsic motivation for behavior change by helping patients explore and resolve their ambivalence through strategic questioning, reflective listening, and emphasizing patient autonomy rather than direct persuasion 1
The approach works by helping patients identify discrepancies between their current behaviors and their personal values or life goals, then supporting them in resolving this ambivalence 3
The "MI Spirit" foundation requires an empathetic, collaborative, and nonjudgmental demeanor that respects patient autonomy 1
The OARS framework provides the structural foundation for MI conversations, including open-ended questions, affirmations, reflections, and summaries 5

The US Preventive Services Task Force recommends the "5 R's" model for structuring motivational conversations, which includes relevance, risks, rewards, roadblocks, and repetition 3
Motivational interviewing is most strongly supported for substance abuse and dependence disorders, where it manages resistance and increases readiness to change in patients experiencing defensiveness, ambivalence, guilt, and shame 6
Brief MI counseling helps ambivalent patients enter treatment programs, engage with mutual help meetings, or agree to pharmacotherapy trials for substance dependence 6
MI demonstrates modest but significant effectiveness for smoking cessation, with one-time short MI sessions of less than 20 minutes showing efficacy 3
Increasing evidence shows MI is most effective for adolescent counseling about contraception and sexual health when using patient-centered approaches 8

Brief MI sessions are effective, even single sessions under 20 minutes show benefit, making this feasible for busy clinical settings 3
MI by primary care physicians appears somewhat more successful than by counselors, though both are effective 3
Common pitfalls, such as giving complex messages, can be managed through MI by maintaining the empathetic, nonjudgmental stance while helping patients explore their own values and goals 4
