Given the theoretical and methodological limitations, there is insufficient knowledge about the psychometric properties and internal structure of quality of life (QOL) measurements for patients with dementia living in nursing homes. The present study aimed to confirm the validity and reliability of the Geriatric Quality of Life-Dementia scale (GQOL-D) to measure the QOL of patients with dementia in nursing homes and analyze their QOL based on the validated GQOL-D factor structure.
The GQOL-D was used to assess QOL. A convenience sampling method was used to recruit patients with dementia or mild cognitive impairment from six nursing homes in two cities. In order to confirm the validity and factor structure of the scale, both exploratory factor analysis and confirmatory factor analysis were employed. An independent t-test and a one-way analysis of variance were performed to examine the difference in the QOL across general characteristics.
The original factor model was not appropriate to assess the QOL of dementia patients living in nursing homes because the models did not show adequate fit indices. The results support a two-factor structure: environmental and personal factors. Our findings suggest that the internal consistency and construct validity of the proposed two-factor model are adequate, and the GQOL-D is a useful tool for assessing the QOL of dementia patients living in nursing homes.
This factor structure model of environmental and personal aspects is a useful theoretical framework for designing and evaluating interventions for people with dementia and providing integrated person-centered care for people with dementia in nursing homes.
由于理论和方法上的限制，对于居住在养老院中的痴呆症患者的生活质量（QOL）测量的心理测量特性和内部结构知之甚少。本研究旨在确认老年痴呆症生活质量量表（GQOL-D）用于测量养老院中痴呆症患者生活质量的有效性和可靠性，并根据经过验证的 GQOL-D 因子结构分析他们的生活质量。
使用 GQOL-D 评估生活质量。采用便利抽样法从两个城市的六家养老院招募痴呆症或轻度认知障碍患者。为了确认量表的有效性和因子结构，同时进行了探索性因子分析和验证性因子分析。采用独立样本 t 检验和单因素方差分析检验一般特征对生活质量的差异。
原始因子模型不适用于评估居住在养老院中的痴呆症患者的生活质量，因为模型没有显示出足够的拟合指数。研究结果支持两因素结构：环境因素和个人因素。我们的研究结果表明，所提出的两因素模型的内部一致性和结构效度是足够的，GQOL-D 是评估居住在养老院中的痴呆症患者生活质量的有用工具。
环境和个人方面的这种因子结构模型为设计和评估针对痴呆症患者的干预措施以及为养老院中的痴呆症患者提供综合的以患者为中心的护理提供了有用的理论框架。
