Memory self-ratings are often used in primary care practice and social surveys due to its relative ease of administration. Yet their usefulness to accurately measure individuals' memory-related cognitive function is largely unknown. This article assesses the construct validity of self-rated memory for measuring memory-related cognitive function among middle-aged and older adults (45+ years) in China using a national sample ( = 13,690) from the China Health and Retirement Longitudinal Study. We first compare self-rated memory with a number of well-established memory tests and then investigate the role of sociodemographic factors in determining self-reports conditional on memory test performance. We find that self-rated memory is only weakly correlated with memory test performance and yields low sensitivity and specificity in detecting individuals with relatively poor memory test performance. We also find evidence for substantial differential item functioning across sociodemographic groups. Our results, therefore, caution against the use of simple self-rated memory measures for memory assessments in primary care or survey research.
由于自我评估记忆相对容易进行,因此在初级保健实践和社会调查中经常使用。然而,其在准确衡量个体与记忆相关的认知功能方面的有用性在很大程度上尚不清楚。本文使用中国健康与退休纵向研究(China Health and Retirement Longitudinal Study)中的全国样本(n=13690),评估了自我评估记忆在衡量中国中老年(45 岁及以上)人群与记忆相关的认知功能方面的结构效度。我们首先将自我评估记忆与多项成熟的记忆测试进行比较,然后调查社会人口因素在记忆测试表现的条件下对自我报告的决定作用。我们发现,自我评估记忆与记忆测试表现仅呈弱相关,并且在检测记忆测试表现相对较差的个体时,其灵敏度和特异性均较低。我们还发现了证据表明,在社会人口统计学群体中存在实质性的项目差异功能。因此,我们的研究结果告诫人们,在初级保健或调查研究中,不要仅使用简单的自我评估记忆测量来评估记忆。
