The validity of instruments is crucial in ensuring that data collected are sound and that these data represent what the instrument claims to measure. When an instrument is revised or used in a different population, it is useful to re-examine its construct validity.
To test the psychometrics properties of an instrument-the revised Families' Importance In Nursing Care-Nurses' Attitudes, designed to measure nurse' attitudes towards involving family in nursing care in an adult acute care setting.
A cross-sectional survey design was used in April-May 2016 with a sample of Enrolled and Registered Nurses (N = 212) to test the factor structure of the revised Families' Importance In Nursing-Nurses' Attitudes instrument. The instrument had 26 items with a five-point Likert response scale. Principle components analysis and exploratory factor analysis were performed with oblique rotations to assess the internal structure of the instrument.
A regional referral hospital in Queensland, Australia.
Using Principal Components Analysis and Principal Axis Factoring, we obtained the same factor structure to that originally identified for the instrument. Our results suggested the removal of six items to refine the instrument and achieve simple structure.
The removal of several items, relabeling of factors and residual cross-loading issues suggest that further revisions to the instrument are needed.
仪器的有效性对于确保所收集的数据是可靠的，并且这些数据代表了仪器声称要测量的内容至关重要。当仪器被修订或在不同人群中使用时，重新检查其构建有效性是很有用的。
检验用于测量成人急性护理环境中护士对参与护理的家庭态度的修订版《家庭对护理的重要性-护士的态度》仪器的心理计量学特性。
2016 年 4 月至 5 月，采用横断面调查设计，对注册护士和登记护士样本（N=212）进行测试，以检验修订后的《家庭对护理的重要性-护士的态度》仪器的因子结构。该仪器有 26 个项目，采用五点李克特量表作答。采用斜交旋转进行主成分分析和探索性因子分析，以评估仪器的内部结构。
澳大利亚昆士兰州的一家区域转诊医院。
使用主成分分析和主轴因子分析，我们得到了与仪器最初确定的相同的因子结构。我们的结果表明，需要删除六个项目以完善仪器并实现简单结构。
删除了几个项目、重新标记因子和残留交叉加载问题表明，仪器需要进一步修订。
