Psychometric Properties of the Persian Version of the Nursing Moral Disengagement Scale

Moral disengagement is a set of cognitive mechanisms through which a person violates his/her moral standards without losing his/her dignity. Therefore, a tool has been designed to measure moral disengagement in nurses. This study aims to determine the psychometric properties of the Nursing Moral Disengagement scale. In this methodological study, 440 nurses working in hospitals of Mashhad were selected by the availability sampling method. The translation was carried out using the forward-backward method. The final version of the tool was psychometrically tested for validity (exploratory and confirmatory factor analysis) and reliability (internal consistency and relative stability). Four factors were extracted in the exploratory factor analysis, and since the factor loadings of all the tool items were higher than 0.3,they were all retained. The tool's general fit indices indicated the model's confirmation and optimal fit. Cronbach's alpha and relative stability coefficients for the whole questionnaire were 0.90 and 0.89, respectively. The study results showed that this tool has good validity and reliability and can therefore measure behaviors related to moral disengagement in nurses, so that appropriate interventions can be designed to reduce these harmful behaviors.
