ObjectivesGlobal, COVID-driven restrictions around face-to-face interviews for healthcare student selection have forced admission staff to rapidly adopt adapted online systems before supporting evidence is available. We have developed, what we believe is, the first automated interview grounded in multiple mini-interview (MMI) methodology. This study aimed to explore test–retest reliability, acceptability and usability of the system.Design, setting and participantsMultimethod feasibility study in Physician Associate programmes from two UK and one US university during 2019–2020.Primary, secondary outcomesFeasibility measures (test–retest reliability, acceptability and usability) were assessed using intraclass correlation (ICC), descriptive statistics, thematic and content analysis.MethodsVolunteers took (T1), then repeated (T2), the automated MMI, with a 7-day interval (±2) then completed an evaluation questionnaire. Admission staff participated in focus group discussions.ResultsSixty-two students and seven admission staff participated; 34 students and 4 staff from UK and 28 students and 3 staff from US universities. Good-excellent test–retest reliability was observed at two sites (US and UK2) with T1 and T2 ICC between 0.65 and 0.81 (pConclusionThese preliminary findings suggest that the system is reliable, generating consistent scores for candidates and is acceptable to end users provided human touchpoints are maintained. Thus, there is evidence for the potential of such an automated system to augment healthcare student selection.
