The Multiple Mini Interview as a Dental School Admission Tool: Can It Predict Noncognitive Traits Associated with Professional Behaviors?

Abstract

The aim of this study was to investigate the reliability and validity of the Multiple Mini Interview (MMI) process and to assess its use as an admission tool to predict noncognitive traits associated with professional behavior during patient care in one cohort of dental students at a single U.S. dental school. Data were analyzed for the 95 candidates who matriculated and graduated as part of the 2017 graduating cohort at the University of Michigan School of Dentistry. All MMI interviewees for one cycle of admissions rotated through ten stations: two traditional interview question stations and eight scenario stations measuring domains that included four questions scored on a five-point Likert scale. Generalizability theory analysis showed the MMI to have good reliability (G Coefficient of 0.74). Station reliabilities (Cronbach's alpha) ranged from 0.88 to 0.92. MMI scores showed a positive significant correlation with students' scores on the Dental Admission Test and Perceptual Ability Test, D1 cumulative GPA, and D4 Patient Management grade. MMI scores positively correlated with professional behaviors relating to three domains-openness, conscientiousness, and emotional stability-thus demonstrating good predictive validity for measuring noncognitive traits associated with professionalism. This study found that the MMI was a reliable and valid tool that predicted key behavioral traits associated with professionalism in dental students.
