Motivational interviewing (MI) is a skill used to help individuals make positive behavior changes and may be beneficial for those who work with undergraduate students. A new training, comprised of online content followed by an in-person workshop, was created and offered to staff members working directly with students at Iowa State University. The aim of this study was to evaluate confidence for using MI-related components pre and post an in-person workshop. To do so, participants completed a survey regarding their confidence in using MI-related skills before and after the workshop. From the survey results, a paired t-test was conducted to examine differences, and effect size was calculated to examine the magnitude of this difference. A significant difference was found pre to post with a small-to-moderate effect size, suggesting the in-person workshop was an important component for building self-efficacy to implement principles of MI in future conversations with students
