Introduction: This study examines the relationship between learning styles and outcomes of interprofessional education (IPE) through co-curricular learning for medical and welfare students.Method: To analyze changes over time, we utilized IPE evaluations of students from Nagasaki University School of Medicine and the Department of Comprehensive Community Care Services, Nagasaki Junshin Catholic University, who participated in either face-to-face or online classes.Results: The learning outcomes from medical and welfare perspectives in IPE significantly increased regardless of the learning style. As for the same perspective on students from each department, the value of many outcomes in face-to-face learning showed significant increases compared to online classes.Discussion: The learning outcomes of IPE in medical and welfare through online classes were considered to have achieved certain results. Additionally, differences in learning outcomes depending on the learning style were thought to be due to variations in understanding between the groups. It was suggested that long-term studies are necessary for effective co-curricular learning in the future.
