Background: Improving surgical safety is one of the objectives of the National Patient Safety Plan. Assessing the perception of nurses will contribute to a greater commitment to its application. Objectives: To construct and validate a questionnaire to evaluate patient safety in the operating room (OR). Methodology: Methodological research study. Development of a questionnaire, submitted to a Delphi panel, and study of its psychometric characteristics in a sample of 1,001 nurses. Construct validity study carried out by exploratory factorial analysis with Varimax rotation and convergent and discriminating validity. Its reliability was assessed using Cronbach's alpha coefficient (a). Results: The validation by the Delphi panel resulted in a version composed of 79 items, which assess nine areas of patient safety (APS). Correlation matrices (p > 0.00) and Kaiser-Meyer-Olkin measures > 0.8 in the APS 9 ensure good adequacy of the factorial model, which groups the items into 19 dimensions with a values between 0.66 and 0.98. Conclusion: The questionnaire meets the validity requirements, revealing the high capacity for research use.
