记忆问题的主观报告和客观证据之间的关系一直存在争议，文献中出现了混合的结果。关于测试表现的客观变化与家庭成员/朋友和训练有素的临床医生对认知变化的看法之间的关系，人们知之甚少。这些关系进行了探讨，使用5年的纵向数据，以人口为基础的加拿大健康与老龄化研究。使用基于标准回归（SRB）的方法和可靠变化指数（RCI）来确定记忆测试性能的统计可靠恶化，该指数考虑了老化和实践效果。在基线时没有认知障碍（NCI）的人的子样本中，可靠的测试分数下降与临床医生和知情人的评级之间存在中度相关。然而，没有发现与记忆困难的主观报告。这些发现对目前的轻度认知障碍（MCI）标准，包括认知下降的主观，知情者和/或临床医生评级的影响。(c)2005年美国国家神经心理学学会。由爱思唯尔有限公司出版。保留所有权利。
The relation between the subjective report of memory problems and objective evidence of the same has been debated with mixed results appearing in the literature. Less is known about the relation between objective change in test performance and the perceptions of cognitive change from family members/friends and trained clinicians. These relations were explored using 5-year longitudinal data from the population-based Canadian Study of Health and Aging. Statistically reliable deterioration in memory test performance was determined using a standardized regression-based (SRB) approach and a Reliable Change Index (RCI) that accounts for aging and practice effects. Among a subsample of persons with no cognitive impairment (NCI) at baseline, there was a moderate relation between reliable test score decline and ratings made by clinicians and informants. No relation, however, was found with the subjective reports of memory difficulties. These findings hold implications for current mild cognitive impairment (MCI) criteria which include subjective, informant and/or clinician ratings of cognitive decline.
