Using the Many-Facet Rasch Model to analyse and evaluate the quality of objective structured clinical examination: a non-experimental cross-sectional design.

ABSTRACT: OBJECTIVES:Sources of bias, such as the examiners, domains and stations, can influence the student marks in objective structured clinical examination (OSCE). This study describes the extent to which the facets modelled in an OSCE can contribute to scoring variance and how they fit into a Many-Facet Rasch Model (MFRM) of OSCE performance. A further objective is to identify the functioning of the rating scale used. DESIGN:A non-experimental cross-sectional design. PARTICIPANTS AND SETTINGS:An MFRM was used to identify sources of error (eg, examiner, domain and station), which may influence the student outcome. A 16-station OSCE was conducted for 329 final year medical students. Domain-based marking was applied, each station using a sample from eight defined domains across the whole OSCE. The
