To document the prevalence of self- and informant report of cognitive problems, usually referred to as "subjective cognitive complaints" (SCCs), in a community-dwelling sample of older adults and to examine the relationship between SCCs and objective impairment, mood, and personality measures.
Eight hundred twenty-seven nondemented community-dwelling adults aged 70-90 years.
Participants were asked 24 SCC questions, including the Memory Complaint Questionnaire (MAC-Q), and completed neuropsychological testing in the domains of memory, language, executive function, visuospatial skills, and psychomotor speed. The Geriatric Depression Scale, Goldberg Anxiety Scale, and Neuroticism, Openness, and Conscientiousness from the NEO-Five Factor Inventory were used as measures of participants' psychological status. Informants completed 19 SCC questions, including a modified short Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE).
Overall, 95.5% of participants or their informants endorsed at least one SCC. Although participants were more likely to endorse a memory complaint, informants seemed more accurate in endorsing a complaint when cognitive impairment was objectively present. SCC correlated with participants' scores on measures of depression, anxiety, neuroticism, and inversely with measures of openness and conscientiousness. Age, education, and sex had little impact on these effects. Regression analysis showed that psychological factors explained the number of complaints more than cognitive performance.
The usefulness of SCCs as a criterion for mild cognitive impairment is questioned because of their high prevalence and their relationship to psychological factors. This may be helpful for clinicians to bear in mind when presented with patients with cognitive complaints.
记录认知问题（通常称为“主观认知抱怨”[SCC]）在社区居住的老年人群体中的发生率，并研究 SCC 与客观损害、情绪和人格测量之间的关系。
827 名无痴呆的社区居住的 70-90 岁成年人。
参与者被问到 24 个 SCC 问题，包括记忆抱怨问卷（MAC-Q），并完成了记忆、语言、执行功能、视空间技能和心理运动速度等领域的神经心理学测试。使用老年抑郁量表、戈德堡焦虑量表和 NEO-五因素人格量表中的神经质、开放性和尽责性作为参与者心理状态的测量。知情人完成了 19 个 SCC 问题，包括修改后的简短老年认知衰退知情人问卷（IQCODE）。
总体而言，95.5%的参与者或其知情人至少有一个 SCC。尽管参与者更有可能承认记忆抱怨，但当认知障碍客观存在时，知情人似乎更准确地承认抱怨。SCC 与参与者的抑郁、焦虑、神经质评分相关，与开放性和尽责性评分呈负相关。年龄、教育和性别对这些影响影响不大。回归分析表明，心理因素比认知表现更能解释抱怨的数量。
由于 SCC 的高发生率及其与心理因素的关系，SCC 作为轻度认知障碍的标准的有用性受到质疑。这可能有助于临床医生在面对有认知抱怨的患者时牢记这一点。
