Although a majority of adults live with a close relationship partner, little is known about whether and how partners' momentary affect and physiology covary, or "coregulate." This study used a dyadic multilevel modeling approach to explore the coregulation of spouses' mood states and cortisol levels in 30 married couples who sampled saliva and reported on mood states 4 times per day for 3 days. For both husbands and wives, own cortisol level was positively associated with partner's cortisol level, even after sampling time was controlled. For wives, marital satisfaction weakened the strength of this effect. Partner's negative mood was positively associated with own negative mood for both husbands and wives. Marital satisfaction fully moderated this effect, reducing the strength of the association between one's own and one's partner's negative mood states. Spouses' positive moods were not correlated. As expected, within-couple coregulation coefficients were stronger when mood and cortisol were sampled in the early morning and evening, when spouses were together at home, than during the workday. The results suggest that spouses' fluctuations in negative mood and cortisol levels are linked over several days and that marital satisfaction may buffer spouses from their partners' negative mood or stress state.
尽管大多数成年人都与亲密的伴侣生活在一起，但对于伴侣的情绪和生理是否会相互影响，或者“共同调节”，人们知之甚少。本研究采用双变量多层次模型方法，探讨了 30 对已婚夫妇在 3 天内每天 4 次采样唾液并报告情绪状态时的配偶情绪状态和皮质醇水平的共同调节情况。对于丈夫和妻子来说，自身的皮质醇水平与伴侣的皮质醇水平呈正相关，即使控制了采样时间也是如此。对于妻子来说，婚姻满意度减弱了这种影响的强度。对于丈夫和妻子来说，伴侣的负面情绪与自己的负面情绪呈正相关。婚姻满意度完全调节了这种影响，降低了自己和伴侣负面情绪状态之间的关联强度。配偶的积极情绪并不相关。正如预期的那样，当情绪和皮质醇在清晨和傍晚在家中与配偶在一起时，而不是在工作日采样时，夫妻之间的共同调节系数更强。研究结果表明，配偶之间的负面情绪和皮质醇水平波动在几天内是相互关联的，婚姻满意度可能会使配偶免受伴侣的负面情绪或压力状态的影响。
