本研究使用289名成年人（年龄在18-89岁之间）的30天日记研究数据来模拟压力源堆积对个人日常消极影响（NA）和积极影响（PA）的影响，并测试这些影响的年龄差异。具体来说，我们开发了一种新的方法来操作和模拟应力源堆积，并使用广义混合模型评估这种方法，考虑到高度倾斜的每日NA数据的伽马响应分布。研究结果表明，在一周的时间内，压力源的堆积与个体每日NA的增加显著相关，超过了并发压力源的影响。研究结果还表明，应激源积累和并发应激的影响是相加的，而不是相乘的。年龄与应激源积累有显著的相互作用，因此年龄越大，NA对应激源积累的反应性越低。然而，我们没有发现NA对并发日常压力源的反应性与年龄相关。每日PA与每日压力或压力源堆积无关。本研究提出的应激源堆积的可操作性定义为文献提供了一种新的方法来模拟应激的动态效应，并提供了将急性应激源的影响从应激源堆积的影响中分离出来的新方法。本研究中发现的年龄差异表明，老年人在处理压力源堆积方面发展了有效的情绪调节技能，但他们对急性日常压力源的反应方式与年轻人相似。
This study used data from a 30-day diary study with 289 adults (age range 18–89 years) to model the effects of stressor pile-up on individuals’ daily negative affect (NA) and positive affect (PA) and to test for age differences in these effects. Specifically, we developed a new approach to operationalize and model stressor pile-up and evaluated this approach using generalized mixed models, taking into account the gamma response distribution of the highly skewed daily NA data. Findings showed that pile-up of stressors over a 1-week period was significantly coupled with increases in individuals’ daily NA above and beyond the effect of concurrent stressors. Findings also showed that the effects of stressor accumulation and concurrent stress were additive rather than multiplicative. Age interacted significantly with stressor accumulation so that a higher age was associated with less NA reactivity to stressor pile-up. Yet, we did not find such an age-related association for NA reactivity to concurrent daily stressors. Daily PA was not associated with daily stress or with stressor pile-up. The operational definition of stressor pile-up presented in this study contributes to the literature by providing a new approach to model the dynamic effects of stress, and by providing new ways of separating the effects of acute stressors from the effects of stressor pile-up. The age differences found in the present study suggest that older adults develop effective emotion regulation skills for handling stressor pile-up, but that they react to acute daily stressors in a similar way than younger adults.
