OBJECTIVE
It has been proposed that cumulative stress, one's experience of chronic stressors across multiple domains, worsens health by altering the extent to which daily stressors impact daily affect and physical symptoms. Recent work confirms that high cumulative stress exacerbates the association between daily stressor exposure and increased daily negative affect, though it remains untested the extent to which cumulative stress and daily stressor exposure interact to predict daily symptoms.
METHOD
We employed data from the second wave of the midlife in the U.S. Survey (N = 2,022; M = 56.2; 57.2% female) to examine whether levels of cumulative stress compound daily symptoms on days with (vs. without) stressful events. Experiences of life stressors across eight domains, occurrence of daily stressors, and occurrence, number, and severity of daily physical symptoms were analyzed using multilevel modeling.
RESULTS
Greater cumulative stress and experiencing (vs. not experiencing) a daily stressor independently increased the odds of occurrence, number, and severity of daily symptoms (ps ≤ .016). Moreover, after adjusting for covariates (e.g., sociodemographic characteristics, chronic health conditions, percent of days with reported stressors, and health behaviors), the associations between daily stressor exposure and odds of occurrence, number, and severity of daily symptoms were potentiated as levels of cumulative stress increased (ps ≤ .009).
CONCLUSIONS
The negative implications of daily stressor exposure for daily health may be most pronounced in those who report higher levels of cumulative stress across multiple life domains and across time. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
目的
有人提出，累积性压力——一个人在多个领域经历慢性压力源的程度——通过改变日常压力源对日常情绪和身体症状的影响程度，从而恶化健康状况。最近的研究工作证实，高累积性压力会加剧每日压力源暴露与每日负性情绪增加之间的关联，尽管累积性压力和每日压力源暴露之间相互作用从而预测每日症状的程度仍有待检验。
方法
我们利用美国中年生活研究第二波的数据（N=2022；M=56.2；57.2%为女性），检验在有（无）压力事件的日子里，累积性压力水平是否会使每日症状恶化。使用多层次模型分析了八个领域的生活压力源经历、每日压力源的发生情况以及每日身体症状的发生、数量和严重程度。
结果
更大的累积性压力和经历（不经历）每日压力源会独立增加每日症状的发生、数量和严重程度的几率（p 值≤.016）。此外，在调整了协变量（例如，社会人口统计学特征、慢性健康状况、报告有压力源的天数百分比以及健康行为）后，随着累积性压力水平的增加，每日压力源暴露与每日症状发生、数量和严重程度几率之间的关联也得到了加强（p 值≤.009）。
结论
每日压力源暴露对日常健康的负面影响在报告多个生活领域和跨时间的累积性压力水平较高的人群中可能最为明显。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
