Validation of the reduced version of the Brazilian Scale of Moral Distress in Nurses

Abstract

Objective: to validate a model of the reduced version of the Brazilian Scale of Moral Distress in Nurses. Method: methodological study, with a sample of 269 nurses from a public university hospital in southern Brazil. A sociodemographic questionnaire and the Brazilian Moral Distress Scale for Nurses were used. Descriptive statistics, structural equation modeling, and invariance analysis between age groups were used. Results: regarding profile, professionals aged between 31 and 40, women, married, and specialists prevailed. The structural model fitted the data with acceptable fit indices. The proposed model showed excellent internal consistency, convergent validity, and discriminant validity. The analysis of the structural model revealed that the five hypotheses were confirmed, and the invariance between the age groups indicates that the way the variables are conceptualized, measured, and interrelated in the model does not affect the results, regardless of the groups compared. Conclusion: the scale achieved satisfactory psychometric indicators, proving to be suitable for use, maintaining the relevant validation elements per dimension, and offering practical advantages. Further research is suggested to deepen our understanding of the consequences of moral distress and to develop effective strategies for managing it.
