This study assessed the reliability and stability of care preferences and life evaluations among older adults with and without dementia. The study also examined spouse proxy predictions of partner responses. Test-retest reliability over 1 week, stability over 1 year, and proxy knowledge were all moderate to good, but lower for people with dementia. In all 3 areas, however, there was broad interindividual variability. People with dementia may become less reliable and stable in their self-reports, and some spouse proxies may have flawed knowledge about their partner, but dementia status alone is not sufficient to presume poor reliability or knowledge.
本研究评估了患有和未患有痴呆症的老年人护理偏好和生活评价的可靠性及稳定性。该研究还考察了配偶对伴侣反应的代理预测。1周内的重测信度、1年内的稳定性以及代理知晓度均为中等至良好，但痴呆症患者的这些指标较低。然而，在所有这三个方面，个体间存在广泛差异。痴呆症患者在自我报告中可能变得不那么可靠和稳定，一些配偶代理人可能对其伴侣的了解存在偏差，但仅痴呆症状态不足以推断可靠性差或知晓度低。
