Abstract：
We examined age differences in the within-person relationships among perceived stress (PS), perceived stress reactivity (PSR), and depressive affect (DA) as well as potential mechanisms of depression with a longitudinal moderated mediation model. Participants from the Notre Dame Study of Health & Wellbeing (N = 572) completed two to four waves of yearly assessments. Sequentially built multilevel models, in which year was nested within person, illustrated that only midlife adults experience an exacerbated effect of within-person fluctuations in PSR on the relationship between within-person PS and DA levels (γ41 = -.004, p < .01). Findings further suggest that PSR accounts for the PS-DA relationship. Furthermore, older adults illustrate successful emotion regulation strategies at the yearly level-resisting the negative ramifications of years of greater PS and PSR, whereas midlife adults who experience years of greater PSR would particularly benefit from stress management interventions and monitoring of DA levels.
摘要：
我们检查了感知压力(PS)之间人内关系的年龄差异，感知应激反应性(PSR)，和抑郁情绪（DA）以及潜在的抑郁机制与纵向调节调解模型。圣母院健康与福祉研究（N=572）的参与者完成了两到四波年度评估。顺序构建的多层模型，哪一年嵌套在人体内，说明只有中年成年人经历人内PSR波动对人内PS和DA水平之间关系的加剧影响(γ41=-.004，p<.01)。研究结果进一步表明，PSR解释了PS-DA关系。此外，老年人在年度水平上展示了成功的情绪调节策略-抵抗多年来更大的PS和PSR的负面影响，而经历多年PSR较高的中年成年人将特别受益于压力管理干预和DA水平监测.
