Translation and psychometric validation of the Peer Evaluation Scale for Team-based Learning (PES-TBL) for Chinese medical students

Aim: To translate, culturally adapt and evaluate the psychometric properties of the Peer Evaluation Scale for Team-based Learning (PES-TBL) for students in nursing and medical disciplines.

Background: Effective peer evaluation tools provide a more scientific and objective assessment of collaborative learning. However, there is a lack of peer evaluation instruments designed for group learning in China.

Design: A cross-sectional, methodological study.

Methods: The PES-TBL was first translated and adapted into Chinese. A panel of 10 experts in nursing and clinical medicine education evaluated the content validity. The psychometric properties of scale were assessed in a sample of undergraduate and postgraduate students.The reliability of the PES-TBL was assessed. Exploratory and confirmatory factor analyses were performed to explore and verify its dimensionality and construct validity.

Results: A total of 564 students were included, the overall content validity index was 0.975. The exploratory factor analysis confirmed a three-factor structure, including responsibility, initiative and collaboration. The reliability of the scale was adequate, with Cronbach's α (0.983), Spearman-Brown split-half index (0.916) and re-test reliability index (0.955). Confirmatory factor analysis showed a three-factor structure explaining 84.336 % of the total variance. All model fit indices fell within acceptable ranges, indicating good structural validity for the Chinese version of the PES-TBL.

Conclusion: The Chinese version of PES-TBL proved to be a reliable tool to test group learning performance in both nursing and medical students and it could be a broadly useful instrument in nursing and medical education.
