Reliability and Validity of the Multiple Mini Interview in the General Entrance Examination for Medical Schools at a National University

Abstract

Introduction: Although MMI is considered an interview technique with good reliability and va-lidity in foreign countries, few universities have implemented it in admissions because of its high cost in Japan. In this study, we examined the reliability and validity of the MMI at a medicaleducation institution that introduced the MMI for general entrance examinations. Methods: Twenty-nine students who took the MMI in 2022 were included in the study. For reliability, G study and D study were conducted based on generalizability theory. For validity, the total score of the MMI and the total score of the achievement test were plotted as a scatter plot and compared with the currently known status. Results: G coefficient was 0.336. There was no significant cor-relation between MMI and test scores.Unwilling applicants had lower MMI scores. Discussion and Conclusion: Regarding reliability, we found that our MMI needs to be improved. The validity of the MMI needs further investigation, but the results suggest that the MMI may be related to factors important to university administration.
