Multiple mini-interviews is a predictor of students’ academic achievements in early undergraduate medical years: a retrospective study

BACKGROUND: Our study determined Multiple Mini-Interview (MMI) effectiveness in evaluating specific skill sets based on medical students’ performances during the undergraduate years and compared the academic performances of medical students who appeared for onsite/online MMI. METHODS: A retrospective study of 140 undergraduate medical students between 2016 and 2020 included data on age, gender, pre-university results, MMI scores, and examination results. Appropriate non-parametric tests were applied to compare the students’ MMI and academic performances. RESULTS: Ninety-eight students from cohorts 12 to 15 had an overall MMI score of 69.0(IQR: 65.0—73.2)/100 and an overall Cumulative Grade Point Average(GPA) of 3.64 (3.42—3.78)/5.0. Spearman’s correlation revealed a significantly positive relationship between MMI and cGPA (rho = 0.23) and GPA from the first 2 semesters (GPA1 rho = 0.25, GPA2 rho = 0.27). This observation was similar to that for station A in the first year (cGPA rho = 0.28, GPA1 rho = 0.34, GPA2 rho = 0.24), and in station B (GPA4 rho = 0.25) and D (GPA3 rho = 0.28, GPA4 rho = 0.24) in the second year. Of twenty-nine cohort16 students, 17(58.6%) underwent online and 12(41.4%) offline modes of MMI assessment, respectively. The overall median MMI score was 66.6(IQR: 58.6—71.6)/100, and the overall median cGPA was 3.45 (3.23—3.58)/5.0. When comparing the median marks of cohort16 groups, the online group scored significantly higher marks for station D than the offline group (p = 0.040). CONCLUSION: Correspondence between MMI scores and cGPA predicted MMI scoring during student selection and entry process might ensure the success of their academic performance in medical school.
