Life satisfaction reflects an individual's general evaluation of their overall quality of life. It has been hypothesized that relationship status (i.e. state of intimate relationship such as marriage, unmarried cohabiting, dating with others, single or divorce) may influence individual life satisfaction. However, there is little accessible empirical evidence that allows us to explore this proposition. Using a large sample of young adults (n = 1031) from the Human Connectome Project (HCP), we showed that compared to other relationship statuses (e.g., individuals who were single or divorced, individuals who dated others, and etcetera), marriage/cohabitation subjects not only revealed a higher life satisfaction plus higher emotional and instrumental support, but also reduced perceived stress, which contributed to higher life satisfaction. Using general linear model with cortical thickness as the dependent variable, life satisfaction was negatively associated with the left superior frontal gyrus (SFG) and bilateral middle frontal gyrus (MFG). Interestingly, both right MFG and left SFG could interact with relationship status to predict self-reported life satisfaction, in addition to being associated with a much lower life satisfaction in non-married/cohabiting individuals. These effects were independent of emotional, instrumental support, and socioeconomic status. Besides, statistical significance of the moderation effect pertaining to relationship status was lost once perceived stress was included as a covariate into the moderation model. Our findings provided empirical evidence for the potentially positive role of relationship status in life satisfaction, and also showed that remission of stress may be a critical factor.
生活满意度反映了个体对其整体生活质量的总体评价。有人假设，人际关系状况（即亲密关系的状态，如婚姻、未婚同居、与他人约会、单身或离婚）可能会影响个体的生活满意度。然而，很少有可获得的经验证据可以让我们探讨这一观点。利用来自人类连接组计划（HCP）的大量年轻成年人（n=1031）样本，我们表明，与其他关系状况（例如单身或离婚的个体、与他人约会的个体等）相比，婚姻/同居者不仅表现出更高的生活满意度和更高的情感和工具支持，而且还降低了感知压力，这有助于提高生活满意度。使用皮质厚度作为因变量的一般线性模型，生活满意度与左侧额上回（SFG）和双侧额中回（MFG）呈负相关。有趣的是，右侧 MFG 和左侧 SFG 都可以与关系状况相互作用，从而预测自我报告的生活满意度，此外，与未婚/同居者相比，两者都与生活满意度低得多相关。这些影响独立于情感、工具支持和社会经济地位。此外，一旦将感知压力作为协变量纳入调节模型，与关系状况有关的调节效应的统计学意义就会丧失。我们的研究结果为关系状况在生活满意度方面可能发挥的积极作用提供了经验证据，同时也表明，压力的缓解可能是一个关键因素。
