Translation and validation of the revised “Rushton Moral Resilience Scale” in Greek

Background High levels of moral resilience among nurses are crucial to maintain or restore moral integrity in response to moral challenges during their duties. Aim To translate and validate the revised “Rushton Moral Resilience Scale” (RMRS) in Greek. Methods We collected data from 316 nurses in Greece during July 2023. We translated the RMRS in Greek applying the forward-backward method and we adapted it in the Greek context. We used three other valid tools to estimate the concurrent validity of the RMRS: “Moral Distress Thermometer” (MDT) to measure levels of moral distress; “Quiet Quitting Scale” (QQS) to measure levels of quiet quitting; single item burnout measure to measure job burnout. We performed confirmatory factor analysis (CFA) to examine the construct validity of the RMRS. Results We found that the RMRS had excellent reliability since all intraclass correlation coefficients in test-rest reliability analysis were higher than 0.993 and statistically significant (p < 0.001). Moreover, Cronbach’s coefficients alpha for the response to moral adversity scale, personal integrity scale, relational integrity scale, moral efficacy scale, and total scale were 0.652, 0.795, 0.678, 0.640, and 0.778 respectively. Our confirmatory factor analysis confirmed the four-factors structure of the scale: response to moral adversity, personal integrity, relational integrity, and moral efficacy. Concurrent validity of the Greek version of the RMRS was exceptional since we found statistically significant correlations between the RMRS and MDT, QQS, and the single item burnout measure. Conclusions The revised “Rushton Moral Resilience Scale” is a reliable and valid tool to measure moral resilience in healthcare workers.
