The presentstudy aims to validate the questionnaire EIIP-23 to Portuguese, evaluating its psychometric prop-erties. Methods: This is methodological research for the process of cross-cultural translation andadaptation. Results: The process of cross-cultural translation and adaptation were satisfactory. Thecommittee of experts reached an agreement of more than 90% in the first evaluation for all theitems. The internal consistency of the nurse-patient interaction scale 22-PT (NPIS-22-PT) was 0.864.Exploratory and confirmatory factor analyses were carried out in the NPIS-22-PT model, with threefactors.

Conclusion: The translated version produced a good qualitypsychometric evaluation, and can be considered a valid, trustworthy, and useful instrument toevaluate the nurse-patient interactions in Portugal.
