Abstract：
Life satisfaction refers to an individual\' s cognitive evaluation of the overall quality of their life considering the various aspects therein. Although the existing research has demonstrated the between-person relationship between negative life events and life satisfaction based on retrospective measures, less is known about this relationship at the within-person level. A daily diary method could examine this within-person relationship and decrease systematic recall biases. Therefore, this study investigated the link between daily negative life events and daily life satisfaction, as well as the mediating role of perceived stress and the moderating role of trait rumination in 146 young adults (Mage = 20.75, SD = 1.35) using a 14-day daily diary design. Multilevel regression analysis showed that daily negative life events had negative predictive effects on daily life satisfaction. In addition, the multilevel 1-1-1 mediation analysis indicated that daily perceived stress mediated the association between daily negative life events and daily life satisfaction. More importantly, the mediating effect of perceived stress was moderated by trait rumination, with the within-person mediating effect being stronger for individuals with higher than those with lower trait rumination tendencies. These findings contribute to the understanding of the underlying pathways in the relationship between daily negative life events and daily life satisfaction and provide a new perspective for improving individuals\' life satisfaction.
摘要：
生活满意度是指个人对其生活质量的整体认知评估，考虑其中的各个方面。尽管现有研究已经证明了基于回顾性测量的负面生活事件与生活满意度之间的人与人之间的关系，在人内层面，人们对这种关系知之甚少。每日日记方法可以检查这种人内关系，并减少系统的回忆偏见。因此,这项研究调查了日常负面生活事件与日常生活满意度之间的联系，以及使用14天的每日日记设计在146名年轻人（Mage=20.75，SD=1.35）中感知压力的中介作用和特质沉思的调节作用。多水平回归分析显示,日常负性生活事件对日常生活满意度有负向预测作用。此外,多水平1-1-1中介分析显示,每日感知压力介导了每日负性生活事件与日常生活满意度之间的关联.更重要的是,感知压力的中介作用受到特质沉思的调节，对于具有较高特征反思性倾向的个体，人内中介效应更强。这些发现有助于理解日常负面生活事件与日常生活满意度之间关系的潜在途径，并为提高个人生活满意度提供了新的视角。
