Using the bivariate dual change score approach, the present study investigated the directionality of the SMC-OMP association in a sample of healthy older adults (N = 2,057) from the Virginia Cognitive Aging Project. The sample was assessed throughout 10 years, five time points, and the impact of education, depressive symptoms, and low-memory functioning was tested. The Memory Functioning Questionnaire was used to assess SMC. There was a lack of longitudinal association with no significant coupling effects found between subjective and objective memory. After including depressive symptoms as a covariate, Frequency of Forgetting significantly predicted subsequent negative changes in OMP . A similar result was found for the low-memory functioning group after the inclusion of depression, with the frequency of memory complaints predicting subsequent memory decline . Our results do not support a predictive value of SMC without accounting for the influence of depressive symptoms and low-memory functioning.
本研究采用双变量对偶变化分数法，在弗吉尼亚认知老化项目的健康老年人样本（N = 2057）中，调查了主观记忆完整性（SMC）与客观记忆表现（OMP）关联的方向性。该样本在10年中历经五个时间点进行评估，并测试了教育程度、抑郁症状和低记忆功能的影响。使用记忆功能问卷来评估SMC。主观记忆与客观记忆之间缺乏纵向关联，未发现显著的耦合效应。将抑郁症状作为协变量纳入后，遗忘频率显著预测了OMP随后的负面变化。在纳入抑郁因素后，低记忆功能组也得到了类似结果，记忆抱怨频率预测了随后的记忆衰退。我们的结果表明，在不考虑抑郁症状和低记忆功能影响的情况下，SMC没有预测价值。
