One way of assuring professional behavior in doctors is to ensure that only those students who are likely to behave professionally are admitted to medical school. The purpose of this study is to evaluate the usefulness of an instrument to evaluate the professional bearing of applicants at the time of the medical school interview. Specifically, the present investigation sought to develop an admissions instrument (Assessing Professionalism in Medical School Applicants) to assess demographic and non-cognitive qualities indicative of professionalism that would be less labor intensive and less costly than either the multiple mini-interview (MMI) or the multi-station admissions protocol (MOR).
