Impact of sociodemographic characteristics of applicants in multiple mini-interviews

Abstract

Background: Multiple mini-interviews (MMI) are commonly used for medical school admission. This study aimed to assess if sociodemographic characteristics are associated with MMI performance, and how they may act as barriers or enablers to communication in MMI.Methods: This mixed-method study combined data from a sociodemographic questionnaire, MMI scores, semi-structured interviews and focus groups with applicants and assessors. Quantitative and qualitative data were analyzed using multiple linear regression and a thematic framework analysis.Results: 1099 applicants responded to the questionnaire. A regression model (R2 = 0.086) demonstrated that being age 25–29 (β = 0.11, p = 0.001), female and a French-speaker (β = 0.22, p = 0.003) were associated with better MMI scores. Having an Asian-born parent was associated with a lower score (β = −0.12, p < 0.001). Candidates reporting a higher family income had higher MMI scores. In the qualitative data, participants discussed how maturity and financial support improved life experiences, how language could act as a barrier, and how ethnocultural differences could lead to misunderstandings.Conclusion: Age, gender, ethnicity, socioeconomic status and language seem to be associated with applicants’ MMI scores because of perceived differences in communications skills and life experiences. Monitoring this association may provide guidance to improve fairness of MMI stations.
