A new study of older European couples reveals that an individual’s life satisfaction is strongly connected to that of their romantic partner. This emotional link is influenced by factors like caregiving roles, health status, and social connections, highlighting the deeply intertwined nature of well-being in later life. The findings were published in the journal Social Indicators Research.
Researchers have long sought to understand what contributes to a person’s sense of well-being, especially as they age. While factors like personal health and financial security are known to be important, less is understood about how the happiness of the people closest to us affects our own.
A team of researchers led by Terhi Auvinen of the University of Eastern Finland aimed to fill this gap by exploring the connection between partners’ life satisfaction. Their work was guided by theories like “linked lives” and “family systems theory,” which propose that individuals in a family unit are interdependent, and an event affecting one member can ripple through to affect others.
The investigation focused on older couples for several reasons. As people enter their later years and often retire, their social worlds can narrow, making the spousal relationship a more central source of companionship and support. This stage of life also brings an increased likelihood of health challenges, which can lead to one partner taking on a caregiving role for the other. These dynamics suggest that a partner’s state of mind and general satisfaction with life could have a particularly strong influence on an individual’s own well-being. Understanding this connection is important for developing effective social and health policies for aging populations.
To conduct their analysis, the researchers used a vast and comprehensive dataset from the Survey of Health, Ageing and Retirement in Europe (SHARE). This long-term project collects information from tens of thousands of adults over the age of 50 across 28 different countries. The team analyzed seven waves of survey data, allowing them to track changes in couples’ lives over many years. Their final sample included 24,760 opposite-sex couples, amounting to more than 155,000 separate observations over time.
In the survey, participants rated their life satisfaction on a scale from 0 (“completely dissatisfied”) to 10 (“completely satisfied”). The researchers used a statistical technique known as fixed effects regression. This method is well-suited for tracking changes over time because it focuses on what happens within an individual’s life, effectively controlling for stable personal traits like personality or background that do not change. The analysis also accounted for other time-varying factors, including each partner’s health, functional limitations, employment status, perceived financial situation, and whether they were giving or receiving care.
The study’s main finding was a robust and consistent association between the life satisfaction of partners. On average, for every one-point increase in a partner’s reported life satisfaction, an individual’s own satisfaction increased by approximately 0.3 points. This link held firm even after the researchers controlled for a wide range of personal and household characteristics, such as health problems, financial strain, or changes in social networks. The connection was also equally strong for both men and women.
“It is well known that being in a relationship generally increases well-being and life satisfaction, as do other well-functioning social relationships. In many ways, we are dependent on the people around us, and their experiences and challenges are also reflected in ourselves,” said doctoral researcher Terhi Auvinen from the University of Eastern Finland. While about two-thirds of couples reported similar levels of life satisfaction, the study also found that in more than a third of cases, partners reported differing levels of happiness.
The researchers then explored specific circumstances that might alter the strength of this emotional link. They found that health disparities played a part. The association between partners’ happiness was slightly weaker when only one person in the relationship had chronic health conditions or disabilities. A similar pattern emerged in caregiving situations. The connection was weakest when an individual was the sole provider of personal care for their partner, suggesting that this demanding role may create a degree of emotional distance.
An individual’s social life outside the relationship also appeared to be a factor, particularly for women. For female respondents, the link to their partner’s life satisfaction was strongest when their own social network was very small, consisting of only one person they could confide in. As a woman’s network of friends, family, and other confidants grew larger, her well-being became less tied to her partner’s. For men, the size of their social network did not appear to change the strength of this connection.
“Women with a broad social network may be emotionally less dependent on their partner. However, the size of a man’s social network did not have an effect on how strongly their partner’s life satisfaction influenced their own,” Auvinen said.
The study also revealed significant differences across nations. The association between partners’ life satisfaction was strongest in several Eastern and Southern European countries, including Hungary, Slovakia, and Greece. In contrast, the link was weakest in Western and Northern European nations that tend to report higher overall life satisfaction, such as Finland, Denmark, Sweden, and Switzerland. This suggests that in societies with a higher baseline of well-being and potentially stronger social safety nets, individuals may be more emotionally independent within their romantic relationships.
These findings have important implications for how we think about well-being in aging populations. They show that life satisfaction is not merely an individual experience but a shared one within a couple. This suggests that interventions aimed at improving a person’s quality of life may have positive spillover effects on their partner. For instance, providing support to an individual with a chronic illness could also boost the well-being of their spouse. Considering the couple as a unit could make health and social policies more effective.
“SHARE enables us to seek solutions to questions and consequences related to population ageing. For decision-makers, it provides reliable and comparable information to support policymaking,” said Professor Ismo Linnosmaa of the University of Eastern Finland.
The authors acknowledge some limitations to their work. While their analysis shows a strong association, it cannot definitively prove that one partner’s happiness causes the other’s. The influence is likely reciprocal, with partners affecting each other simultaneously. The study was also limited to older, opposite-sex couples, meaning the results may not generalize to younger people or same-sex couples.
