Background: Improving health outcomes requires health care practitioners to work collaboratively with clients to make healthy lifestyle changes. Motivational interviewing (MI) is an evidence-based approach found to evoke and support behavior change.
Objective: The aim of this study was to examine changes over time in pre-service professional students' confidence in their MI skills after a 15-week interprofessional MI course.
Methods: Students ( = 22) completed a newly developed 24-item Motivational Interviewing Confidence Survey (MICS pre and post participation in the course). Summary statistics, initial scale reliability assessment and -tests were carried out.
Results: MICS was a reliable measure (Cronbach's = 0.98) and detected significant changes in students' self-perceived skill set. Using -tests, significant differences were noted in pre- and post-assessments in students' confidence in their skills; students ( values<0.001) demonstrated significant gains in confidence on 23 of 24 MICS items.
Conclusion: After participating in the course, students' confidence in their MI skills improved significantly. Adding pre-service training in MI may increase future healthcare practitioners' confidence in their MI skills and improve their capacity to engage in individually tailored, client-driven practice.
