The emotional well-being of persons with dementia is an aspect of their quality of life. We examined the stability of informant-rated and self-reported emotion, and the influence of mental status and physical dependence on ratings; we modeled concordance between ratings at both the within- and between-person levels of analysis. We used multilevel modeling to examine data collected over 12 days from 31 nursing home residents. We found significant within-person variation in both informant-rated and self-reported emotion, such that between 40% and 60% of the overall variance in each occurred within persons. We found little correspondence between or within persons between ratings of the informants and residents, regardless of mental status. We recommend statistical techniques that describe these high levels of daily variation in persons with dementia.
痴呆症患者的情绪健康是其生活质量的一个方面。我们研究了信息提供者评定的情绪和自我报告的情绪的稳定性，以及精神状态和身体依赖对评定的影响；我们在个体内和个体间分析层面建立了评定之间的一致性模型。我们使用多层次模型来分析从31名养老院居民身上收集的、为期12天的数据。我们发现，信息提供者评定的情绪和自我报告的情绪在个体内均存在显著差异，以至于每种情绪的总体差异中有40%至60%发生在个体内部。无论精神状态如何，我们发现信息提供者和居民的评定之间以及个体内部的评定之间几乎没有对应关系。我们推荐使用统计技术来描述痴呆症患者日常情绪变化的高水平情况。
