Table 4 Results of the decision study, showing G-coefficients for MMIs with four to eight stations, stratified by question format (PBQs, SQs, or PBQs and SQs) (n = 40)

From: Reliability and acceptability of six station multiple mini-interviews: past-behavioural versus situational questions in postgraduate medical admission
