Quality of life (QoL) is important to nursing home (NH) residents, yet QoL is only publicly reported in a few states, in part because of concerns regarding measure stability. This study used QoL data from Minnesota, one of the few states that collects the measures, to test the stability of QoL over time. To do so, we assessed responses from two resident cohorts who were surveyed in subsequent years (2012-2013 and 2014-2015). Stability was measured using intra-class correlation (ICC) obtained from hierarchical linear models. Overall QoL had ICCs of 0.604 and 0.614, respectively. Our findings show that person-reported QoL has adequate stability over a period of one year. Findings have implications for higher adoption of person-reported QoL measure in long-term care.
生活质量（QoL）对养老院（NH）居民很重要，但由于对测量稳定性的担忧，只有少数几个州公开报告 QoL 数据，这在一定程度上是因为对测量稳定性的担忧。本研究使用了明尼苏达州的 QoL 数据，明尼苏达州是少数几个收集这些措施的州之一，以测试 QoL 随时间的稳定性。为此，我们评估了在随后几年（2012-2013 年和 2014-2015 年）接受调查的两个居民队列的反应。使用来自分层线性模型的组内相关系数（ICC）来衡量稳定性。总体 QoL 的 ICC 分别为 0.604 和 0.614。我们的研究结果表明，在一年的时间内，个体报告的 QoL 具有足够的稳定性。这些发现对长期护理中更高采用个体报告的 QoL 测量具有重要意义。
