We investigated subjective cognitive complaints (SCCs), as well as physical and mental health factors, in adults and older adults. U.S. residents (N = 2,962) were recruited via the Amazon Mechanical Turk platform and completed a 90-item survey. Overall, 493/1930 (25.5%) of younger adults and 278/1032 (26.9%) of older adults endorsed SCCs. Analyses revealed worse physical and mental health characteristics in the SCC+ compared to the SCC- group, with primarily medium (Cohen’s d = 0.50) to large (0.80) effect sizes. Age did not moderate relationships between SCCs and physical/mental health. Results suggest that SCCs are associated with a diverse set of negative health characteristics such as poor sleep and high body mass index, and lower levels of positive factors, including happiness and wisdom. Effect sizes of psychological correlates were at least as large as those of physical correlates, indicating that mental health is critical to consider when evaluating SCCs.

我们调查了成人和老年人的主观认知抱怨 (SCC) 以及身心健康因素。美国居民 ( N = 2,962) 通过 Amazon Mechanical Turk 平台招募并完成了一项包含 90 项的调查。总体而言，493/1930 (25.5%) 的年轻人和 278/1032 (26.9%) 的老年人认可 SCC。分析显示，与 SCC- 组相比，SCC+ 的身心健康特征更差，主要是中等（Cohen's d= 0.50) 到大 (0.80) 的影响大小。年龄并未调节 SCC 与身心健康之间的关系。结果表明，SCC 与一系列不同的负面健康特征相关，例如睡眠不足和高体重指数，以及较低水平的正面因素，包括快乐和智慧。心理相关性的影响大小至少与物理相关性的影响大小一样大，表明在评估 SCC 时，心理健康是需要考虑的关键因素。
