Cultural adaptation of the revised Basel Instrument for Rationing of Care to the Turkish context: a study of validity and reliability

Background: Studies have shown that nurses do not complete one or more necessary nursing care elements in their last shift due to lack of time. The Basel Extent of Rationing Nursing Care (BERNCA) instrument is one of the most used scales to measure the rationing of nursing care. Aim: This study is aimed to culturally adapt the revised BERNCA (BERNCA-R) instrument to the Turkish language and to test its validity and reliability. Methods: A cross-sectional and methodological study was used. The instrument was adapted in three stages: translation and adaptation, content validity testing and validity and reliability. Data were obtained from 350 nurses working in two public acute care hospitals in Turkey, between September 2019 and January 2020. The descriptive statistics, content validity index, exploratory and confirmatory factor analyses, Cronbach's & alpha;, Guttman split-half and inter-item reliability analyses were performed for the analysis of the data. Results: The Turkish version of the BERNCA-R instrument with a 27-item and three-subscales (monitoring, daily care and needs and psychosocial care) structure was found to have acceptable and good fit indices. Conclusion: The Turkish version of the BERNCA-R instrument is valid and reliable tool to measure rationing of nursing care.
