BACKGROUND/AIMS: To compare memory evaluations in healthy older people and people with Alzheimer's disease (AD) and present standardised individual and dyadic methods for classifying degree of memory awareness in the participants with dementia.
Cross-sectional study evaluating awareness of memory functioning and performance and providing normative data for healthy individuals and couples, together with comparison data from people with AD.
As a group, older people are reasonably accurate raters of their own memory functioning and performance, although considerable individual differences can be observed, and control dyads show good comparative accuracy. Comparing normative data from the control group to data from participants with AD confirms that significant overestimation is a frequent feature among people with dementia, with approximately two-thirds showing this pattern, although significant under-estimation is also reliably observed in a small proportion of people with dementia. Different types of measure elicit different profiles of memory awareness in participants with dementia.
Normative data from older individuals and couples provides useful percentile-based indices for determining level of memory awareness in people with dementia.
背景/目的：比较健康老年人和阿尔茨海默病（AD）患者的记忆评估，并提出用于分类痴呆患者记忆意识程度的标准化个体和对偶方法。
横断面研究评估记忆功能和表现的意识，并为健康个体和夫妇提供规范数据，以及来自 AD 患者的比较数据。
作为一个群体，老年人对自己的记忆功能和表现的评价相当准确，尽管可以观察到相当大的个体差异，并且对照组的对偶对具有良好的比较准确性。将对照组的规范数据与 AD 患者的数据进行比较，证实了在痴呆患者中，显著的高估是一种常见特征，大约三分之二的患者表现出这种模式，尽管在一小部分痴呆患者中也可靠地观察到显著的低估。不同类型的测量方法在痴呆患者中引发不同的记忆意识模式。
来自老年人和夫妇的规范数据为确定痴呆患者的记忆意识水平提供了有用的基于百分位数的指标。
