Objective Structured Clinical Examination Perception Scale (OSCEPS) for Health Sciences Students: A Psychometric Evaluation Study.

Abstract

Objective Structured Clinical Examinations (OSCE) is an objective assessment approach that enables the evaluation of students' practical skills by simulating real clinical scenarios. This scale is specifically designed to evaluate the attributes and characteristics of the OSCE from the perspective of health sciences students, thereby filling a crucial gap in the existing assessment methods. This research conducted a methodological design involving 220 students from the faculties of medicine and nursing between 2022 and 2023. Data were gathered using a "Descriptive Form" and "OSCEPS." Factor analyses were performed for research and validation to ascertain the scale's factorial structure. The factorial analysis was used to test the structural validity of the scale. A structure consisting of 19 items was developed. The Cronbach's alpha coefficient was 0.943. Fit indices resulting from the study were RMSEA = 0.084; GFI = 0.839; CFI = 0.902; IFI = 0.902; RFI = 0.824; NFI = 0.843; TLI = 0.889. This study proves that the OSCEPS is a highly reliable and valid scale with strong psychometric properties. It effectively assesses health sciences students' perceptions of OSCE, thereby enhancing the credibility and usefulness of this assessment tool.
