The aim of the study was to perform translation and cultural adaptation, as well as to assess the validity and reliability of the Polish version of the Neonatal Extent of Work Rationing Instrument (NEWRI) questionnaire for evaluating care rationing in neonatal intensive care units (NICUs) in Poland.

Material and methods:
Participants were prospectively recruited at the University Clinical Hospital in Wroclaw, Poland, and the study conducted from January 2018 – June 2018. The adaptation process involved translation of survey items following the guidelines for cross-cultural translation and evaluation of psychometric properties, as well as an assessment of construct validity, reliability, and internal consistency of the NEWRI using Cronbach’s alpha.

113 professionally active nurses (n=90) and midwives (n=23) were enrolled in the study. Cronbach’s alpha for the entire instrument was 0.982. Results for subscales: life support and technology-oriented nursing care – Cronbach’s alpha – 0.95, parental support and teaching and infant comfort care – 0.95, patient surveillance – 0.92, care coordination and discharge planning – 0.79. All items of the questionnaire were found to have a positive discriminatory power.

The present findings indicate a high level of reliability and validity of the translated questionnaire, fully comparable to that of the original. The questionnaire can be used for evaluating care rationing in NICUs.
