Results: 96 items were maintained in the instrument, reorganized into six domains, with reliability ranging from adequate to excellent, with a total instrument precision of 0.89. Conclusion: The instrument proved to be valid, reliable and ready for use in clinical practice in the studied context. More studies should be carried out for application in other scenarios.
