Inconsistent results are reported so far in the literature on the relationship between subjective memory complaints (SMC) and objective memory performance. Mixed findings triggered the need to investigate whether other potential mediating variables, such as mood and non-memory domains, affect the relationship between SMC and memory performance.
The present study aimed to contribute in clarifying the relation between subjective and objective memory considering the potential role of mood and visuospatial/executive functions.
Six hundred and sixty Italian community-dwelling adults (52-91 years old) were enrolled. Italian version of Montreal Cognitive Assessment Test (MoCA), Geriatric Depression Scale and Subjective Memory Complaints Questionnaire (SMCQ) were administered. Four subsamples were composed according to the following criteria: (a) participants with high visuospatial/executive function (VSE) score at MoCA and high mood; (b) participants with high VSE score and low mood; (c) participants with low VSE score and high mood and; (d) participants with low VSE score and low mood.
Preliminarily, two confirmatory factor analysis have set the one-factor structure of SMCQ as the best fitting model. Diagnostic accuracy of the SMCQ in discriminating high and low memory score was assessed. ROC analyses confirmed that a low score in executive tasks was associated with poor reliability of the SMCQ. On the contrary, well-preserved executive functions and high mood levels ensured a good reliability of SMCQ in detecting memory problems.
Although mood is a key mediator in the relationship between subjective and objective memory, preserving executive functions is essential for ensuring the accuracy of memory self-appraisal in adulthood and elderly.
目前文献中关于主观记忆抱怨（SMC）与客观记忆表现之间的关系报告结果不一致。混合发现促使人们需要调查其他潜在的中介变量，如情绪和非记忆领域，是否会影响 SMC 与记忆表现之间的关系。
本研究旨在通过考虑情绪和视空间/执行功能的潜在作用，阐明主观记忆与客观记忆之间的关系。
纳入了 660 名意大利社区居住的成年人（52-91 岁）。进行了蒙特利尔认知评估测试（MoCA）、老年抑郁量表和主观记忆抱怨问卷（SMCQ）的意大利语版本。根据以下标准组成了四个亚组：（a）MoCA 中具有高视空间/执行功能（VSE）评分和高情绪的参与者；（b）具有高 VSE 评分和低情绪的参与者；（c）具有低 VSE 评分和高情绪的参与者；（d）具有低 VSE 评分和低情绪的参与者。
初步的验证性因子分析确定 SMCQ 的单因素结构为最佳拟合模型。评估了 SMCQ 区分高记忆评分和低记忆评分的诊断准确性。ROC 分析证实，执行任务的得分低与 SMCQ 的可靠性差相关。相反，保留良好的执行功能和高情绪水平确保了 SMCQ 在检测记忆问题时具有良好的可靠性。
尽管情绪是主观记忆与客观记忆之间关系的关键中介因素，但保留执行功能对于确保成年人和老年人记忆自我评估的准确性至关重要。
