Implementation of Motivational Interviewing Training in Dental Education and Research-A Scoping Review

Motivational interviewing (MI) is an evidence-based counseling approach that enhances behavior change by strengthening an individual's motivation. While MI research in dental education is growing, the scope of MI training programs has not been systematically examined. This review assesses the implementation of MI training in dentistry.

A scoping review followed the PRISMA-ScR checklist and JBI manual for evidence synthesis. A systematic search (May 2023) using MeSH terms, keywords, and operators was conducted in Medline (Ovid), Embase (Ovid), CINAHL, PsycINFO (Ovid), Web of Science, and ProQuest. Articles were screened via Covidence, and data were extracted based on variables informed by the DoCTRINE framework.

Of 17 studies, 70.6% were US-based, and 64.7% were published after 2010. MI training targeted dental hygiene and dentistry students (47% each) through lectures, role-play, e-learning, and workshops. Evaluations used pre-post questionnaires, recorded interactions, and tools like MITI, MISC, and OSCE. Training duration varied from single sessions (11.7%) to longitudinal programs (82.3%), enhancing students' confidence, communication, and public health readiness. However, skill retention required ongoing reinforcement. Barriers included time constraints, patient resistance, and limited faculty support. High-quality reporting (DoCTRINE score) was observed in 47% of studies.

MI training enhances dental students' communication and patient-centered care. Long-term skill retention requires continued practice, and hybrid instructional strategies can improve scalability. Faculty competency and structured longitudinal training are crucial for effective MI implementation.
