Psychometric properties of the persian version of the physician teaching self-efficacy questionnaire.

Introduction: Theories and numerous empirical studies indicate teaching performance and students' learning progress are affected by teaching self-efficacy. Therefore, the present study examines the psychometric properties of the Persian version of the physician teaching self-efficacy questionnaire.

Methods: The 16-item physician teaching self-efficacy questionnaire was translated from English to Persian and back-translated to English and then administered to 242 medical teachers from six medical universities. To assess construct validity, researchers made use of confirmatory factor analysis. To check the reliability and validity of the physician teaching self-efficacy questionnaire, we used internal consistency, discriminant, convergent, and criterion validity.

Results: PLS-SEM results substantiated the original three factor structure of the questionnaire which is dyadic, triadic, and self-regulation. For all sub-scales, internal consistency- measured by Cronbach's alpha and composite reliability, convergent validity- measured by factor loading and AVE, and discriminant validity- measured by cross-loading, Fornell-Larcker, and HTMT metrics- confirmed the construct reliability and validity of the questionnaire. A positive correlation was, also, fund between teaching motivation and experience with the physician teaching self-efficacy questionnaire scales, proving the criterion validity of the questionnaire.

Conclusion: The Persian version of physician teaching self-efficacy questionnaire is a valid, highly reliable, and multidimensional tool to measure physicians' clinical teaching self-efficacy working in medical universities.
