The relationship between memory complaints and objective memory performance remains poorly understood, particularly in young and middle aged people. We studied the relationship between reports of memory complaints and objective memory performance, and the possibility of differentiating good and poor reporters across the lifespan based on concordance between reported abilities and objectively assessed performance. This cross-sectional study enrolled 292 healthy individuals, aged 18 to 87 years, able to perform common activities of daily living and without neurological or psychiatric conditions or systemic diseases likely to interfere with cognition. No correlation between memory complaints, as assessed by the Subjective Memory Complaints scale (SMC) score and the objective memory performance, evaluated by the long-delay free recall (LDFR) score of the California Verbal Learning Test (CVLT), was found, even when grouping the participants by decade. The SMC score was influenced by the presence of depressive symptoms. Participants who were more educated, female and younger tended to have a higher CVLT-LDFR score. Younger subjects were more likely to have good memory performance and report few memory complaints than older subjects. In conclusion, there are differences in the reliability of memory reporting across the lifespan, younger subjects being more likely to correctly report good memory than older subjects.
记忆主诉与客观记忆表现之间的关系仍未得到充分理解，尤其是在年轻人和中年人中。我们研究了记忆主诉报告与客观记忆表现之间的关系，以及基于报告能力与客观评估表现之间的一致性，在整个生命周期中区分记忆主诉报告良好者和不佳者的可能性。这项横断面研究纳入了292名年龄在18至87岁之间的健康个体，他们能够进行日常生活中的常见活动，且没有可能干扰认知的神经或精神疾病或全身性疾病。通过主观记忆主诉量表（SMC）评分评估的记忆主诉与通过加利福尼亚言语学习测试（CVLT）的长延迟自由回忆（LDFR）评分评估的客观记忆表现之间，即使按十年对参与者进行分组，也未发现相关性。SMC评分受抑郁症状的影响。受教育程度更高、女性和更年轻的参与者往往具有更高的CVLT-LDFR评分。与年长受试者相比，年轻受试者更有可能具有良好的记忆表现且报告较少的记忆主诉。总之，在整个生命周期中，记忆报告的可靠性存在差异，年轻受试者比年长受试者更有可能正确报告良好的记忆。
