Nudging is a subtle behavioral intervention that has been successful in various domains such as healthy eating and energy conservation, yet its application in mental health remains underexplored. This study examines the effect of nudging to increase engagement with online mental health resources in a university setting. We assigned 2539 first-year undergraduate and graduate students in China to either a nudging group, which received course information augmented with behavioral cues (including framing effects and social norms), or a control group, which received only basic course information. Outcomes measured included self-reported willingness to enroll, willingness to recommend enrollment, and actual enrollment actions. Results indicated that students in the nudging group demonstrated significantly higher engagement levels than those in the control group across all metrics. These findings suggest the potential of nudging strategies to effectively enhance college students’ participation in online mental health education.
