Quality of life (QoL) is recognized as an important patient-reported outcome measure. Assessing QoL in older people with cognitive impairment is a challenge due to discrepancies in the collection of data via proxies versus self-report. This study aimed to assess the psychometric properties of the self-reported EQ-5D (including the EQ index and EQ visual analog scale (VAS)) in nursing homes residents with cognitive impairment and to analyze its validity based on scales included in the comprehensive geriatric assessment.
Cross-sectional, multicenter study analyzing the feasibility, acceptability, reliability, and validity of the EQ-5D based on 251 self-administered questionnaires in a sample of nursing home residents with cognitive impairment. Reference scales were those from the comprehensive geriatric assessment, equivalent to the five dimensions of the EuroQol.
The EQ index was 0.31 (0.37) and the EQ VAS was 35.96 (29.86), showing adequate acceptability and feasibility. Cronbach's alpha was 0.723. The EQ index and EQ VAS, as outcome variables for multiple linear regression models including CGA titration scales, showed better validity for the EQ index than the EQ VAS.
As a self-administered generic scale, the EQ-5D-3L could be a good tool for QoL assessment in nursing home residents with cognitive impairment.
生活质量(QoL)被认为是一种重要的患者报告结局指标。由于通过代理人报告与自我报告收集数据存在差异,评估认知障碍老年人的生活质量具有挑战性。本研究旨在评估认知障碍养老院居民自我报告的EQ-5D(包括EQ指数和EQ视觉模拟量表(VAS))的心理测量特性,并基于综合老年评估中包含的量表分析其有效性。
横断面多中心研究,基于对251名认知障碍养老院居民样本进行的自我管理问卷调查,分析EQ-5D的可行性、可接受性、可靠性和有效性。参考量表来自综合老年评估,等同于欧洲五维度健康量表的五个维度。
EQ指数为0.31(0.37),EQ VAS为35.96(29.86),显示出足够的可接受性和可行性。Cronbach's α系数为0.723。作为包括CGA滴定量表的多元线性回归模型的结果变量,EQ指数和EQ VAS相比,EQ指数显示出更好的有效性。
作为一种自我管理的通用量表,EQ-5D-3L可能是评估认知障碍养老院居民生活质量的良好工具。
