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妇的关系质量会更高。


情感反应被定义为日常压力源引发的人体内负面情绪的增加，与个人福祉有着明确的联系。先前的研究将情感反应概念化为一种内心现象，反映了对自身压力源的反应。在这里，我们概念化了人际反应，检查一个人对浪漫伴侣日常压力的反应。在四项纵向二元研究中，我们研究了对伴侣压力的反应如何预测关系质量评估。在刚起步的夫妇中，通过每周（研究 1；N = 152）和每日（研究 2；N = 144）日记评估对伴侣压力源的反应，可以积极预测伴侣关系质量。在这两项研究中，这种关联都是由伴侣对反应的看法来调节的。此外，在研究 1 的 8 周内和研究 2 的 13 个月内，对伴侣压力的反应对伴侣关系质量的下降起到了缓冲作用。在关系的后期阶段，对伴侣压力的反应与关系质量的相关性减弱。在已建立的夫妻样本中（研究 3 和 4，Ns 分别 = 164 和 208），对伴侣压力的反应并不能直接预测伴侣关系质量或随着时间的推移调节其轨迹。总体而言，四项研究的主要模式描绘了刚起步的关系所特有的关系幸福感的画像。通过其将情感反应置于伴侣之间的新颖框架，本研究对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）。
