目的：确定主观记忆主诉(SMC)是否与居住在社区的健康老年人在客观认知测量和心理因素上的表现有关。队列由65岁及以上的成年人组成，没有认知障碍的临床证据(n=125)。受试者接受：CogState计算机化神经认知成套测验、前瞻性回溯性记忆问卷、个性和生活意义测量。SMC与较差的执行功能指标相关(p=0.001)。SMC也与延迟回忆受损有关(p=0.006)，但在对多次比较进行统计调整后，这一点并不显著。SMC与责任心呈负相关(p=0.004)，与神经质呈正相关(p<；0.001)。SMC得分越高，感受到的压力越大(p=0.001)，应对方式无效(p=0.001)。有助于生命意义的因素与较少的SMC相关(p<；0.05)。SMC可能反映了早期的、微妙的认知变化，并与健康的老年人的人格特征和生活意义有关。
To determine whether subjective memory complaints (SMCs) are associated with performance on objective cognitive measures and psychological factors in healthy, community-dwelling older adults. The cohort was composed of adults, 65 years and older with no clinical evidence of cognitive impairment (n = 125). Participants were administered: CogState computerized neurocognitive battery, Prospective Retrospective Memory Questionnaire, personality and meaning-in-life measures. SMCs were associated with poorer performance on measures of executive function (p = 0.001). SMCs were also associated with impaired delayed recall (p = 0.006) but this did not remain significant after statistical adjustment for multiple comparisons. SMCs were inversely associated with conscientiousness (p = 0.004) and directly associated with neuroticism (p < 0.001). Higher scores on SMCs were associated with higher perceived stress (p = 0.001), and ineffective coping styles (p = 0.001). Factors contributing to meaning-in-life were associated with fewer SMCs (p < 0.05). SMCs may reflect early, subtle cognitive changes and are associated with personality traits and meaning-in-life in healthy, older adults.
