感知压力会导致皮质醇模式失调，包括峰变钝和斜率变平，这与发病率和死亡率风险增加有关。夫妻间的相互依赖为伴侣的压力破坏健康的皮质醇模式提供了一个绝佳的机会。这项研究探讨了个人自己的感知压力和他们的合作伙伴的感知压力如何在一天中塑造皮质醇水平和斜率，以及冲突讨论中的积极和消极行为如何影响压力和皮质醇之间的关联。一对已婚夫妇（n = 43对夫妇，86人）的双方完成了一整天的亲自访问。每位伴侣都完成了感知压力量表，所有夫妇都参与了20分钟的婚姻问题讨论，这些讨论被记录下来，然后使用快速婚姻互动编码系统（RMICS）对积极和消极行为进行编码。合作伙伴还提供了五个唾液皮质醇样本，两个样本在冲突前，三个在冲突后。二元设计和分析提供了一种方法来解释已婚夫妇的数据的相互依赖性，以及使用演员-伴侣相互依赖模型（APIM）来评估配偶的压力对皮质醇的相互影响。与压力较小的伴侣相比，压力较大的伴侣的皮质醇斜率更平坦，后者在一天中表现出更陡峭，因此更健康的下降。无论伴侣的压力如何，个体在一天开始时的皮质醇水平都是相似的，但是在冲突讨论后30分钟，1小时和4小时，与压力较小的伴侣相比，压力较大的伴侣的皮质醇水平更高。夫妻在冲突中的行为缓和了伴侣感知的压力和平均皮质醇之间的关系;当夫妻使用更多的消极和不太积极的行为时，压力更大的伴侣比压力较小的伴侣有更高的平均皮质醇水平。在夫妻发生冲突的一天，有一个感知压力较高的伴侣与皮质醇模式失调有关，包括更高的水平和更平坦的斜坡，但有一个感知压力较低的伴侣与更陡峭，因此更健康的皮质醇下降有关。当夫妻在讨论冲突时更多地使用消极行为而更少地使用积极行为时，伴侣的压力对自己的皮质醇的影响尤其明显。这项研究增加了越来越多的关于婚姻互动与重要的生物节律和健康之间联系的文献。
Perceived stress can lead to dysregulated cortisol patterns, including blunted peaks and flatter slopes, which are associated with increased morbidity and mortality risks. Couples’ interdependence provides a prime opportunity for partners’ stress to disrupt a healthy cortisol pattern. This study examined how individuals’ own perceived stress and their partners’ perceived stress shape cortisol levels and slopes across the day, as well as how positive and negative behaviors during conflict discussions impact associations between stress and cortisol. Both partners of a married couple (n = 43 couples, 86 individuals) completed a full day in-person visit. Each partner completed the Perceived Stress Scale, and all couples engaged in a 20-min marital problem discussion which was recorded and later coded for positive and negative behaviors using the Rapid Marital Interaction Coding System (RMICS). Partners also provided five salivary cortisol samples across the day, two samples before the conflict and three after the conflict. The dyadic design and analyses provided a way to account for the interdependent nature of married couples’ data, as well as to use the Actor-Partner Interdependence Model (APIM) to assess the mutual influence of spouses’ stress on cortisol. Individuals with more stressed partners had flatter cortisol slopes than individuals with less stressed partners, who showed steeper and thus healthier declines across the day. Individuals’ cortisol levels at the beginning of the day were similar regardless of their partners’ perceived stress, but individuals with more stressed partners had higher cortisol levels 30-min, 1 hr, and 4 hr after the conflict discussion than those with less stressed partners. Couples’ behavior during the conflict moderated the relationship between partner perceived stress and average cortisol; when couples used more negative and less positive behaviors, individuals with more stressed partners had higher average cortisol levels than those with less stressed partners. On a day couples experienced conflict, having a partner with higher perceived stress is associated with dysregulated cortisol patterns, including higher levels and flatter slopes, but having a partner with lower perceived stress is linked to steeper and thus healthier cortisol declines. A partner’s stress was particularly consequential for one’s own cortisol when couples used more negative and fewer positive behaviors during a conflict discussion. This research adds to the growing literature on pathways connecting marital interactions to important biorhythms and health.
