Well-adapted and validated quality-of-life measurement models for the nursing home population are scarce. Therefore, the aim of this study was to test the psychometrical properties of the OPQoL-brief questionnaire among cognitively intact nursing home residents. The research question addressed evidence related to the dimensionality, reliability and construct validity, all of which considered interrelated measurement properties.
Cross-sectional data were collected during 2017-2018, in 27 nursing homes representing four different Norwegian municipalities, located in Western and Mid-Norway. The total sample comprised 188 of 204 (92% response rate) long-term nursing home residents who met the inclusion criteria: (1) municipality authority's decision of long-term nursing home care; (2) residential time 3 months or longer; (3) informed consent competency recognized by responsible doctor and nurse; and (4) capable of being interviewed.
Principal component analysis and confirmative factor analyses indicated a unidimensional solution. Five of the original 13 items showed low reliability and validity; excluding these items revealed a good model fit for the one-dimensional 8-items measurement model, showing good internal consistency and validity for these 8 items.
Five out of the 13 original items were not high-quality indicators of quality-of-life showing low reliability and validity in this nursing home population. Significant factor loadings, goodness-of-fit indices and significant correlations in the expected directions with the selected constructs (anxiety, depression, self-transcendence, meaning-in-life, nurse-patient interaction, and joy-of-life) supported the psychometric properties of the OPQoL-brief questionnaire. Exploring the essence of quality-of-life when residing in a nursing home is highly warranted, followed by development and validation of new tools assessing quality-of-life in this population. Such knowledge and well-adapted scales for the nursing home population are beneficial and important for the further development of care quality in nursing homes, and consequently for quality-of-life and wellbeing in this population.
适用于疗养院人群且经过良好验证的生活质量测量模型稀缺。因此，本研究旨在测试认知功能正常的疗养院居民的 OPQoL-brief 问卷的心理测量特性。研究问题涉及维度、可靠性和结构有效性方面的证据，所有这些都考虑了相互关联的测量特性。
2017-2018 年期间，在代表挪威四个不同市的 27 家疗养院中收集了横断面数据，这些疗养院位于挪威西部和中北部。总样本包括符合纳入标准的 204 名长期疗养院居民中的 188 名：（1）市当局决定进行长期疗养院护理；（2）居住时间 3 个月或以上；（3）经负责医生和护士认可的知情同意能力；（4）能够接受采访。
主成分分析和验证性因子分析表明存在单一维度解决方案。最初的 13 项中有 5 项显示出可靠性和有效性较低；排除这些项目后，呈现出一个良好的模型拟合，即一维 8 项测量模型，这 8 项具有良好的内部一致性和有效性。
在该疗养院人群中，最初的 13 项中有 5 项并不是生活质量的高质量指标，它们显示出可靠性和有效性较低。显著的因子负荷、良好的拟合指数以及与所选构念（焦虑、抑郁、自我超越、生命意义、护患互动和生活乐趣）的预期方向的显著相关性，支持了 OPQoL-brief 问卷的心理测量特性。探索在疗养院居住时的生活质量本质是非常有必要的，之后需要开发和验证评估该人群生活质量的新工具。这些针对疗养院人群的知识和适应性强的量表，有利于并对疗养院的护理质量进一步发展，以及对该人群的生活质量和幸福感产生重要影响。
