Cross-cultural adaptation and content validity of the Adverse Events Associated with Nursing Practices instrument

Objective: To conduct the cross-cultural adaptation and evaluate the evidence of content validity of the Adverse Events Associated with Nursing Practices instrument in the Brazilian context. Method: Psychometric study, conducted between June 2021 and February 2023, following the stages of the Patient-Reported Outcomes Measurement Information System protocol. Semantic, idiomatic, experimental and conceptual equivalences were evaluated, along with content validity evidence, considering Content Validity Ratio (CVR) parameters, with the participation of 25 experts. Results: A Brazilian version with 55 items was obtained, demonstrating good linguistic equivalence to the original version (agreement rate=99.2%), and adjustments in the items writing. CVR values remained above 0.60. Cognitive testing indicated good understanding, confirmed by the 31 participants in this stage, with a short application time (average = 17 minutes). Conclusion: The final version of the instrument showed good linguistic equivalence, strong evidence of content validity and a good response process in the Brazilian context.
