Affective reactivity, defined as within-person increases in negative affect triggered by daily stressors, has well-established links to personal well-being. Prior work conceptualized affective reactivity as an intrapersonal phenomenon, reflecting reactions to one's own stressors. Here, we conceptualized reactivity interpersonally, examining one's responses to a romantic partner's daily stressors. Across four longitudinal dyadic studies, we investigated how reactivity to partner stress predicts relationship quality appraisals. In fledgling couples, reactivity to a partner's stressors, assessed via weekly (Study 1; N = 152) and daily (Study 2; N = 144) diaries, positively predicted partner relationship quality. In both studies, the associations were mediated by the partner's perceptions of responsiveness. Furthermore, reactivity to partner stress buffered against declines in partner relationship quality over 8 weeks in Study 1 and 13 months in Study 2. The relevance of reactivity to partner stress for relationship quality diminished in the later stages of relationships. Among samples of established couples (Studies 3 and 4, Ns = 164 and 208, respectively), reactivity to partner stress did not directly predict partner relationship quality or moderate its trajectory over time. Overall, the predominant pattern across four studies painted a portrait of relational well-being benefits specific to fledgling relationships. Through its novel framework of situating affective reactivity interpersonally between partners, the present research contributes to both affective science and relationship science.

我的伴侣真的很理解我：对伴侣压力的情感反应预示着新夫妻的关系质量会更高。


情感反应，定义为由日常压力源引发的负面影响在人体内的增加，与个人幸福感有着公认的联系。之前的工作将情感反应概念化为一种人际内在现象，反映了一个人对自身压力源的反应。在这里，我们从人际关系的角度概念化了反应，研究了一个人对浪漫伴侣的日常压力源的反应。在四项纵向二元研究中，我们调查了对伴侣压力的反应如何预测关系质量评估。在初出茅庐的夫妇中，对伴侣压力源的反应性，通过每周评估（研究 1;N = 152）和每日（研究 2;N = 144） 日记，积极预测伴侣关系质量。在这两项研究中，这些关联都是由伴侣对反应性的感知介导的。此外，在研究 1 和 研究 2 中，对伴侣压力的反应性在 8 周内和研究 2 中超过 13 个月时，伴侣关系质量下降。在关系的后期阶段，对伴侣压力的反应性与关系质量的相关性减弱。在已建立夫妇的样本中（研究 3 和 4，分别为 Ns = 164 和 208），对伴侣压力的反应性并不能直接预测伴侣关系的质量或随着时间的推移缓和其轨迹。总体而言，四项研究的主要模式描绘了初出茅庐的关系幸福感的好处。通过其将伴侣之间人际情感反应置于新的框架，本研究为情感科学和关系科学做出了贡献。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
