Subjective memory concerns (SMCs) might be an early indicator of future cognitive decline and conversion to dementia. However, a rich history of mixed findings, moderating factors, and heterogenous methods preclude the usefulness of SMCs in both research and clinical settings. The present study aimed to review some of the factors that might cause mixed results and propose a revised version the Metamemory in Adulthood (MIA) Questionnaire that can be easily implemented to more consistently derive estimates of SMCs. We used factor analysis and regression to investigate the utility of a revised 20-item version of the MIA Change and Capacity subscales. Based on two samples of older adults ( = 382 and = 221), the revised scale showed strong internal reliability and a two-factor structure. Regression analyses supported the incremental validity of the MIA-Revised Change scale in predicting performance on the Rivermead Behavioural Memory Test. By establishing a revised version of a well-known and previously validated questionnaire to assess SMCs, research and clinics can better implement a psychometrically sound measure quickly and easily. Moreover, the revised Change and Capacity subscales provide sufficient divergence to be sensitive to different facets of SMCs in a community dwelling older adult sample.
主观记忆担忧(SMCs)可能是未来认知能力下降和转化为痴呆症的早期指标。然而,既往研究结果不一、存在调节因素且方法各异,这使得SMCs在研究和临床环境中的实用性大打折扣。本研究旨在回顾一些可能导致结果不一致的因素,并提出《成人元记忆问卷》(MIA)的修订版,该问卷能够轻松实施,以便更一致地得出SMCs的评估结果。我们使用因子分析和回归分析来研究修订后的包含20个条目的MIA变化和能力分量表的效用。基于两组老年人样本(分别为382人和221人),修订后的量表显示出较强的内部信度和双因素结构。回归分析支持了MIA修订版变化量表在预测Rivermead行为记忆测试表现方面的增量效度。通过建立一个经过验证的知名问卷的修订版来评估SMCs,研究人员和临床医生能够更快速、轻松地更好地实施一种心理测量学上合理的测量方法。此外,修订后的变化和能力分量表具有足够的差异,能够对社区居住的老年样本中SMCs的不同方面保持敏感。
