This study validates the OSCEPS scale, demonstrating its high reliability and validity for assessing health sciences students' perceptions of Objective Structured Clinical Examinations (OSCE). The scale enhances the credibility of this crucial assessment tool.
Area of Science:
- Medical Education
- Health Professions Education
- Assessment in Healthcare
Background:
- Objective Structured Clinical Examinations (OSCE) are vital for evaluating practical skills in health sciences.
- Existing assessment methods have a gap in evaluating OSCE attributes from a student perspective.
- A validated scale is needed to measure student perceptions of OSCE effectiveness.
Purpose of the Study:
- To develop and validate a scale (OSCEPS) to assess health sciences students' perceptions of OSCE.
- To determine the psychometric properties of the OSCEPS scale.
- To enhance the credibility and utility of OSCE as an assessment tool.
Main Methods:
- Methodological design involving 220 medicine and nursing students (2022-2023).
- Data collection using a "Descriptive Form" and the "OSCEPS" scale.
- Factor analyses (exploratory and confirmatory) to establish factorial structure and validity.
Main Results:
- A 19-item OSCEPS scale was developed.
- High reliability was confirmed with a Cronbach's alpha coefficient of 0.943.
- Strong psychometric properties were indicated by various fit indices (e.g., CFI=0.902, TLI=0.889).
Conclusions:
- The OSCEPS scale is a reliable and valid instrument for measuring student perceptions of OSCE.
- The scale possesses strong psychometric properties.
- OSCEPS enhances the credibility and usefulness of OSCE in health sciences education.
