Psychometric Evaluation of the Revised 16-Item Rushton Moral Resilience Scale Among Iranian Nurses

Background and Purpose: Moral resilience is a key resource for mitigating moral distress, a form of psychological strain that arises when nurses are unable to act according to their ethical values in complex clinical situations. This study evaluated the psychometric properties of the Persian version of the Revised 16-Item Rushton Moral Resilience Scale (RMRS-16) among Iranian nurses. Methods: This cross-sectional study aimed to evaluate the psychometric properties of the Persian version of the RMRS-16 among 400 Iranian nurses using convenience sampling, with validity assessed through forward-backward translation, face, content, exploratory and confirmatory factor analyses, and reliability as well as convergent and divergent validity testing. Results: The Persian RMRS-16 demonstrated satisfactory validity and reliability. Three factors explained 45.08% of the variance, and model fit indices were acceptable. Therefore, reliability, convergent validity, and divergent validity were all acceptable. Conclusions: The RMRS-16 is a valid and reliable instrument for assessing moral resilience among Iranian nurses, supporting workforce well-being and policy development.
