目的社会关系可以有积极和消极的影响，这些联系在老年时尤其明显。这项研究集中在老年夫妇的日常人际生理动态(皮质醇同步)，并调查其与伴侣在场、积极的日常伴侣互动和同理心的关系。方法我们对来自加拿大温哥华和德国柏林的两对老年夫妇(研究1：85对60-87岁的夫妇；研究2：77对年龄66-85岁的夫妇)的数据进行了协调的多水平分析，他们完成了问卷调查，并连续7天每天提供5-7次唾液皮质醇样本。结果在所有研究中，皮质醇(同步)存在显著的二元协变(研究1/2：B=0.04/0.03，p<；.001/.001)。在研究1(b=0.06，p=.003)中，伴侣的存在只与更大的皮质醇同步性有关，而在研究2(b=0.02，p=.187)中没有关联。当伴侣报告之前积极的社会情感互动时，皮质醇同步性更高(研究1：B=0.09，p=.005；研究2：B=0.04，p=.005)。皮质醇同步性与移情关注(b=0.01，p=.590)或观点采择(b=0.02，p=.065)之间没有统计学意义上的相关性。结论在日常生活中，社会纽带时刻与生理同步性交织在一起。在高度同步性的背景下，潜在的重复传递压力对个人健康和关系功能的影响值得进一步研究。
Objective Social relationships can have positive and negative influences, and these associations are particularly pronounced in old age. This study focuses on everyday interpersonal physiological dynamics (cortisol synchrony) in older couples and investigates its associations with partner presence, positive daily partner interactions, and empathy. Methods We conducted coordinated multilevel analyses using data from two samples of older couples from Vancouver, Canada, and Berlin, Germany (study 1:n= 85 couples aged 60-87 years; study 2:n= 77 couples aged 66-85 years), who completed questionnaires and provided salivary cortisol samples five to seven times daily for 7 days. Results Significant dyadic covariation in cortisol (synchrony) was present across studies (study 1/2:b= 0.04/0.03,p< .001/.001). Partner presence was only associated with greater cortisol synchrony in study 1 (b= 0.06,p= .003) but not in study 2 (b= 0.02,p= .187). Cortisol synchrony was higher when partners reported prior positive socioemotional partner interactions (study 1:b= 0.09,p= .005; study 2:b= 0.04,p= .005). There was no statistically significant association between cortisol synchrony and empathic concern (b= 0.01,p= .590) or perspective taking (b= 0.02,p= .065). Conclusions Moments of social bonding are intertwined with physiological synchrony in everyday life. The implications of potential repeated transmission of stress in the context of high synchrony for individual health and relationship functioning warrant further investigation.
