Development and Validation of Medical Students’ Professionalism Assessment Scale (MSPAS) In OSCE: Simulated Patients’ rating scale

Background To provide the reliable and immediate feedback on the medical students’ professionalism during the OSCE, we developed a modified Medical Students’ professionalism assessment scale (MSPAS) which is relevant in the history taking and physical examination OSCE stations. Methods We developed two sets of questionnaires, Medical Students’ Professionalism Assessment ScaleHistory taking (MSPAS-H) and Medical Students’ Professionalism Assessment ScalePhysical Examination (MSPAS-PE).The Cronbach’s alpha correlation coefficient was calculated to determine the internal consistency and exploratory factor analysis was carried out. Results The Content validity index was calculated by using the expert’s rating on relevance and all the 12 items in the MSPAS had above 0.85 of CVI. Reverse scoring was required for item No 4 (MSPAS-H) and item No 5 (MSPASPE). The Cronbach’s alpha was calculated for reliability and found to have 0.87 for MSPAS-H and 0.92 for MSPAS-PE. Discussion All the 6 items in the history taking and 6 items in the physical examination were loaded in each scale with the factor loading of 0.5 and above for all the items. This MSPAS is short and simple scale, it can be completed in a short time period if the simulated patients are provided the proper training on this assessment.
