Objective:to validate an instrument to identify situations that trigger moral distress
in relation to intensity and frequency in primary health care nurses. Method:this is a methodological study carried out with 391 nurses of primary health
care, applied to the Brazilian Scale of Moral Distress in Nurses with 57
questions. Validation for primary health care was performed through expert
committee evaluation, pre-test, factorial analysis, and Cronbach’s alpha.
Results:there were 46 questions validated divided into six constructs: Health
Policies, Working Conditions, Nurse Autonomy, Professional ethics,
Disrespect to patient autonomy and Work Overload. The instrument had
satisfactory internal consistency, with Cronbach’s alpha 0.98 for the
instrument, and between 0.96 and 0.88 for the constructs. Conclusion:the instrument is valid and reliable to be used in the identification of the
factors that trigger moral distress in primary care nurses, providing
subsidies for new research in this field of professional practice.
