Exploring the usefulness of interviewers' training before and after multiple mini interviews [MMI] for undergraduate medical students' selection: was it really helpful?

Objective: To compare the change in interviewers' perception of Multiple Mini Interviews [MMI] after MMI training and after actual MMI experience

Methods: Six sessions were conducted during two weeks [October 26, 2015- to November 6, 2015] to a total of 87 faculty members. The evaluation dealt with 13 items questionnaire for representation of assessors' perception on 5 point rating scale. Assessors rated their perceptions to complete an anonymised questionnaire about rationale behind MMI, the process of MMI, and the use of scoring criteria [rubrics]. In addition, assessors were also asked to rate their level of satisfaction on MMI process after training and after interviews. Wilcoxon Signed Ranks Test [two-tailed] was used to compare participant's pre- and postinterview ratings

Results: With 81.6% response rate, the positive views of assessors about the MMI selection process and the use of scoring criteria [Rubric] to assess the candidate are not altered after experiencing a MMI selection day [p> 0.001]. Assessors [87%] would prefer to be involved in the process of MMI in future

Conclusion: The outstanding consistency of assessors' ratings before and after interview concluded that MMI training sessions were helpful in improving knowledge and skills about MMI process and candidates' assessment criteria [rubrics]
