Nursing Care Interpersonal Relationship Questionnaire: elaboration and validation.

The study did not test whether using the questionnaire improves care, communication, or patient outcomes. All patients came from public primary, secondary, and tertiary services in Fortaleza, Brazil, so results may not apply elsewhere. The final questionnaire does not cover the stress concept from the original theory. The questionnaire is most informative for low to medium effectiveness of nurse-patient relationships and less informative at higher levels. Eighteen of 950 responses were lost due to incompleteness, and the paper does not state the final analysed sample. Some items with low discrimination were kept but excluded from scale interpretation. Content validation was done by nine nurse experts, while semantic testing used patients, so the expert panel was not patient-based.

The study was supported by CNPq, Brazil, process #300799/2015-2, and was extracted from a doctoral dissertation. No commercial sponsor is reported.

Do not conclude that using this questionnaire improves nursing care or patient outcomes. The study checked how well the questionnaire measures patient perceptions in one Brazilian sample; it did not test the questionnaire as an intervention.
