Development of simple, valid and reliable instruments to determine nursing care rationing is a subject of ongoing research. One such instrument, which is gaining popularity worldwide and has significant research applicability, is the Basel Extent of Rationing of Nursing Care (BERNCA) and its revised version, the BERNCA-R. The aim of this study was to translate and adapt the BERNCA-R into a Polish-language version and to assess its reliability and validity in evaluating the level of implicit rationing of nursing care in Poland. Standard methodological requirements were followed during translation and cultural adaptation of the English version of the BERNCA-R questionnaire into Polish. The cross-sectional validation study was conducted between May and September 2017, which included 175 nurses undergoing specialisation and qualification courses at the European Postgraduate Education Centre in Wrocław, Poland. Cronbach's alpha and inter-item correlations were used to analyse the internal consistency of the Polish BERNCA-R questionnaire. The mean total BERNCA-R score was 1.9 points (SD = 0.74) on a scale of 0-4. Cronbach's alpha for the unidimensional scale was 0.96. The mean inter-item correlation was 0.4 (range 0.1-0.84), which indicates high internal consistency. A single-factor solution demonstrated stable loadings above 0.5 for almost all items of the Polish BERNCA-R questionnaire. The study using the Polish BERNCA-R questionnaire demonstrated that the instrument is valid and reliable for use in investigating care rationing in groups of Polish nurses.
开发简单、有效且可靠的工具来确定护理资源分配是当前研究的主题。一种正在全球范围内流行并具有重要研究适用性的工具是巴塞尔护理资源分配量表（BERNCA）及其修订版 BERNCA-R。本研究旨在将 BERNCA-R 翻译成波兰语版本，并评估其在评估波兰护理资源隐性分配水平方面的可靠性和有效性。在将 BERNCA-R 的英文版翻译成波兰语时，遵循了标准的方法学要求进行翻译和文化适应。横断面验证研究于 2017 年 5 月至 9 月在波兰弗罗茨瓦夫欧洲研究生教育中心进行，共纳入 175 名正在接受专科和资格课程培训的护士。采用克朗巴赫α系数和项目间相关性分析波兰 BERNCA-R 问卷的内部一致性。在 0-4 分的量表上，BERNCA-R 问卷的平均总分为 1.9 分（SD=0.74）。单维量表的克朗巴赫α系数为 0.96。平均项目间相关性为 0.4（范围为 0.1-0.84），表明内部一致性较高。单因素解决方案表明，波兰 BERNCA-R 问卷的几乎所有项目的稳定负荷均高于 0.5。使用波兰 BERNCA-R 问卷的研究表明，该工具在调查波兰护士群体中的护理资源分配方面是有效且可靠的。
