Confidence in a Relationship’s Future May Shape Romantic Attachment in Gay and Heterosexual Men

Feeling secure in a romantic relationship is not only about how partners connect with each other in the present moment. According to a new study from researchers in Japan, it may also depend on something less tangible but equally powerful: how confident people are that their relationship will continue into the future. The research, conducted by Assistant Professor Fan Yang of Waseda University’s Faculty of Letters, Arts and Sciences and Mr. Zichen Zhai of Nagoya University’s Graduate School of Education and Human Development, examined whether gay and heterosexual men differ in how they experience romantic attachment, and whether a person’s perception of relationship stability helps explain those differences. The study was published online in the journal BMC Psychology on September 16, 2026.

The theoretical foundation of the work lies in attachment theory, a widely used framework in psychology that describes how adults form emotional bonds with romantic partners. Within this framework, researchers typically distinguish between two dimensions of insecurity. Attachment anxiety involves worrying about being abandoned or feeling uncertain about a partner’s feelings, often leading people to seek constant reassurance. Attachment avoidance, by contrast, involves discomfort with emotional closeness or with relying on a partner, prompting people to keep their partners at a psychological distance. Individuals high on both dimensions are considered more insecurely attached, which can affect relationship satisfaction, communication, and long-term stability.

Previous research on sexual orientation and attachment has produced mixed results, and the Waseda-led team suspected that a key variable had been overlooked: not the objective history of a person’s relationships, but how stable those relationships are perceived to be. For people with diverse sexual identities, expectations about a relationship’s future may be shaped not only by the relationship itself but also by the wider social environment. Concerns about whether a partnership will be accepted by family, friends, and society can influence how secure individuals feel about maintaining their relationships over time, and this sense of external support may feed directly into attachment patterns.

To investigate these questions, the researchers collected questionnaire data from 603 men aged 20 to 29 years living in Shanghai, China. The sample included 303 gay men and 300 heterosexual men, allowing direct statistical comparison between the two groups. Participants completed measures of attachment anxiety and avoidance using a nine-item questionnaire designed to capture the two core dimensions of romantic attachment. They also reported their romantic relationship history, including the number of relationships they had experienced and the duration of their shortest relationship. Among the 510 participants who had experienced at least one romantic relationship, perceived relationship stability was assessed with a single item asking how stable they considered their romantic relationships to be, with responses ranging from very unstable to very stable.

The results revealed a consistent pattern. Gay men reported higher levels of both attachment anxiety and attachment avoidance than heterosexual men. Importantly, these differences remained statistically significant even after the researchers accounted for economic and occupational status, suggesting that the gap in attachment insecurity was not simply a reflection of socioeconomic differences between the groups. This methodological control matters, because socioeconomic factors can independently influence both relationship experiences and psychological well-being, and failing to adjust for them could produce misleading conclusions.

Perhaps the most striking finding emerged when the team compared the two groups’ relationship histories. Gay and heterosexual men reported remarkably similar numbers of romantic relationships and similar durations for their shortest relationships. In other words, the objective contours of their romantic lives looked much alike. Yet when participants were asked how stable they perceived their relationships to be, a clear difference appeared: gay men reported lower perceived relationship stability than heterosexual men. This perceptual gap, rather than any difference in relationship history, proved to be the statistically meaningful factor.

Using statistical mediation analysis, the researchers found that perceived relationship stability accounted for the differences in attachment anxiety and avoidance between gay and heterosexual men. This suggests that the feeling that a relationship has a future may be a critical psychological bridge linking social experience to attachment security. When individuals doubt whether their relationship can endure, whether because of internal doubts or external pressures, they may develop the hallmark features of insecure attachment: heightened anxiety about abandonment and greater avoidance of closeness. Conversely, a strong sense that a relationship is stable and will continue may buffer against these insecurities.

Our findings highlight the critical role of relationship stability in shaping adult attachment patterns, particularly within sexual minority populations, Yang noted in the study’s announcement. The feeling that this relationship has a future may be an important part of romantic security, she explained. The study’s framing implies that romantic security is a two-layered phenomenon. The first layer involves how people experience their relationships day to day, including closeness, trust, and connection. The second layer involves confidence that the relationship will persist into the future. Both layers matter, and the second may be especially vulnerable to social conditions that fall outside the couple’s control.

For people with diverse sexual identities, this sense of stability may depend heavily on whether their relationships feel accepted and supported by families, communities, and the wider social environment. The study was conducted in Shanghai, and while the authors focus on perceptual and psychological mechanisms rather than making broad cultural claims, the findings underscore that attachment insecurity in sexual minority populations cannot be understood in isolation from the social context in which relationships unfold. Where acceptance is uncertain, the perceived future of a relationship may be uncertain as well, and that uncertainty appears to leave a measurable imprint on attachment style.

The practical implications extend to several domains. These findings may be relevant to relationship counseling, mental health support, and services for sexual minority individuals, Yang said. Support may need to consider not only communication between partners, but also concerns about whether the relationship can be accepted, supported, and maintained over time. In other words, therapists and counselors working with gay men may achieve better outcomes by addressing external stressors and acceptance-related concerns alongside the usual focus on interpersonal dynamics within the couple. The study, titled Are gay men more insecurely attached than heterosexual men in romantic relationships? Perceived relationship stability, rather than relationship history, matters, was published in BMC Psychology with the DOI 10.1186/s40359-026-05621-z, and the authors declared no competing interests. As observational research based on self-reported questionnaires from a specific age group in one city, the findings invite replication in other populations and settings. Even so, the central message is clear and potentially far-reaching: the confidence that a relationship has a future may be just as important to romantic security as the relationship itself, and building that confidence may require changes not only within couples but in the societies around them.
