September 15, 2026: 7 Relationship Studies Worth Knowing
This roundup covers seven peer-reviewed articles. Six were published from September 4 through September 10, 2026. One article was published on July 20. It appears as newly resurfaced research after The Times covered it on September 6 and discussed it again on September 7.
Population averages can’t be generalized to individuals
A peer-reviewed conceptual article on person-specific psychology examines the assumptions required when group averages are applied to one person. Published online on September 6, it proposes a two-stage method that begins with repeated observations inside a person or relationship.
The article is a conceptual review, and it doesn’t test one intervention or provide a single effect size. Its proposed methods also require repeated data.
Higher quality financial communication related to higher satisfaction
A month-long study of financial communication followed 136 couples. Both partners rated their financial conversations. Relationship satisfaction was measured at the beginning and end of the month.
Higher-quality financial communication during the month predicted each partner's later satisfaction after baseline adjustment. Conversation frequency showed no comparable association. Couples with stronger satisfaction at the start also reported better financial conversations.
The sample included 136 couples and the study lasted one month. Measures were self-reported. The design can't establish causal direction, and financial integration changed some associations.
Shared religious practice associated with relationship satisfaction and connection
A two-study article about joint religious practice analyzed 501 U.S. and Canadian couples. A seven-day diary study followed 116 of those couples. Both partners reported relationship satisfaction and connection.
In the larger sample, joint practice was associated with relationship quality through feeling inspired by moral goodness and acting responsibly. In the diary study, partners reported more connection on higher-practice days. Satisfaction was slightly lower on those days.
Study 1 was cross-sectional; Study 2 covered seven days. Self-report and selection into religious practice limit causal claims. Couples with no reported religiosity or joint practice were excluded.
Social rejection changes decisions for social participation
A preregistered experiment on rejection and spending enrolled 98 adults. Participants received randomized feedback on simulated Instagram posts. They also made 100 hypothetical purchase choices involving social or nonsocial experiences.
Participants preferred social experiences overall. After negative feedback, they allocated less of their endowment to social options. Rejection appeared to increase the immediate perceived cost of participation.
The sample was modest. Spending was hypothetical, and the rejection came from anonymous online feedback. Behavior inside an established relationship wasn't measured.
Coercive control reshapes how survivors judge themselves
A U.S. study of coercive control and moral injury surveyed 366 women online. The analysis tested whether guilt-related thoughts and self-compassion statistically accounted for the association.
Women reporting more coercive control also reported more distress tied to perceived violations of their own values. Guilt-related thoughts and lower self-compassion accounted for part of that link in the statistical model.
The design was cross-sectional. Statistical mediation can't establish the order in which these experiences developed. The sample included women, so the findings can't describe survivors of every gender.
Older same-sex couples reported more friend-centered close networks
A study of close networks among older couples pooled probability-based U.S. Health and Retirement Study data from 2006 through 2022. It compared adults in same-sex or different-sex coresidential relationships.
Adults in same-sex relationships reported a higher share of friends in their close networks. They reported a lower share of children or immediate relatives. Total network size was similar across relationship groups.
A partnered older adult may rely on chosen ties for closeness and future care. The data were cross-sectional and self-reported. The study covered older adults in coresidential unions, so it doesn't describe single adults or younger couples. Network composition also can't tell us who will provide care later.
Newly resurfaced: shared sense of awe associated with deeper relationship connection
A two-study article about shared awe in romantic relationships included 504 adults in total. The article was published on July 20. The Times covered it on September 6, then published commentary on September 7.
People who reported more shared awe also reported stronger relationship satisfaction. They described more overlap between self and partner. The second study linked shared awe with a deeper sense of relationship meaning.
Both studies were correlational and relied on self-report. Couples with stronger relationships may notice a shared sense of awe more often. The research team was based in the Netherlands, and the public record doesn't establish transfer across every cultural setting.
What these studies add
Overall, these studies support that relationship behaviors are associated with their sequence and the context of the relationship. If you’re noticing changes in your own relationship or with your partner, ask yourself what was the relationship like before the change and what is it like after the change.
