OBJECTIVES We developed an instrument to assess nursing home residents' quality of life (QOL), with a focus on QOL-related factors modifiable through nursing home care, within the South Korean context; then, we tested its validity and reliability. DESIGN The scale was constructed through a literature review, qualitative interviews, expert panel review, and a focus group interview; then, it was validated through survey research. SETTING AND PARTICIPANTS Residents (N = 667) from 42 nursing homes in South Korea participated in scale validation. METHODS Ninety-nine items across 5 dimensions were initially drafted through a literature review and qualitative interview data. The expert panel review and a focus group interview yielded a scale with 31 items across 3 dimensions. Next, using survey data from nursing home residents, we examined the construct and concurrent validity and reliability (using Kuder-Richardson 20) of the 31-item QOL scale. RESULTS Through a series of factor analyses, the 31 items were reduced to 17 items across 2 dimensions: Environment and Services (13 items) and Social Interaction (4 items). This 17-item scale was further examined for model fitness and reliability. The scale had acceptable to good fit (root mean square error of approximation = 0.07 and 0.07; comparative fit index = 0.83 and 0.98 for Environment and Services and Social Interaction, respectively), and good concurrent validity and internal consistency (Kuder-Richardson 20 = 0.72). CONCLUSIONS AND IMPLICATIONS This 17-item scale is a valid and reliable tool to assess nursing home residents' QOL in South Korea, with a focus on factors modifiable through nursing home care. Through more research to test its usefulness, validity, and reliability, the scale can be used as an index of nursing home care quality and contribute to the development of strategies to improve nursing home residents' QOL.

疗养院护理相关生活质量量表的开发和验证

目标 我们开发了一种评估疗养院居民生活质量 (QOL) 的工具，重点关注韩国背景下可通过疗养院护理改变的 QOL 相关因素；然后，我们测试了它的有效性和可靠性。设计 该量表是通过文献综述、定性访谈、专家小组评审和焦点小组访谈构建的；然后，它通过调查研究得到验证。设置和参与者 来自韩国 42 家疗养院的居民 (N = 667) 参与了规模验证。方法 最初通过文献回顾和定性访谈数据起草了 5 个维度的 99 个项目。专家小组审查和焦点小组访谈产生了一个包含 31 个项目的量表，涵盖 3 个维度。接下来，使用疗养院居民的调查数据，我们检查了 31 项 QOL 量表的结构和同时效度和信度（使用 Kuder-Richardson 20）。结果 通过一系列因素分析，将31个条目缩减为2个维度的17个条目：环境与服务（13个条目）和社会互动（4个条目）。进一步检查了这个 17 项量表的模型适用性和可靠性。该量表具有可接受的良好拟合（近似均方根误差 = 0.07 和 0.07；环境和服务以及社会互动的比较拟合指数分别为 0.83 和 0.98），以及良好的并发效度和内部一致性（Kuder-Richardson 20 = 0.72）。结论和意义 该 17 项量表是评估韩国疗养院居民 QOL 的有效且可靠的工具，重点是通过疗养院护理可以改变的因素。
