A new study suggests that people in interracial long-distance romantic relationships engage in lower or higher levels of reflective functioning toward their partners depending on their attachment style. The findings, published in the journal Personal Relationships, indicate that attachment insecurity—whether expressed as anxiety or avoidance—plays a central role in shaping how individuals interpret and respond to their partner’s mental states.
Mentalizing refers to the ability to understand another person’s actions in terms of underlying thoughts, feelings, and intentions. When applied to romantic contexts, this capacity is known as partner reflective functioning. It refers to how well individuals can consider their partner’s mental states during interactions, particularly in times of stress or conflict.
Previous research has shown that higher levels of partner reflective functioning are linked to greater relationship satisfaction, better communication, and more emotional intimacy. However, researchers have also noted that reflective functioning tends to vary depending on the relationship context and the psychological characteristics of the individual. One such factor is attachment style.
Attachment styles refer to enduring patterns in how people relate to others in close relationships, shaped in part by early caregiving experiences. These styles typically fall along two dimensions: attachment anxiety and attachment avoidance. People high in attachment anxiety often worry about being rejected or abandoned. They may be hyperaware of signs that their partner is pulling away and tend to seek reassurance to ease their fears.
In contrast, people high in attachment avoidance tend to keep emotional distance from others. They often prefer self-reliance, may find intimacy uncomfortable, and are less likely to turn to partners for support. People who are high in attachment anxiety or avoidance may struggle to regulate emotions or interpret others’ behaviors accurately, especially when they perceive relationship threats.
Interracial romantic relationships may pose additional challenges to partner reflective functioning. These relationships often involve navigating differences in cultural norms, assumptions, and lived experiences. When partners do not share the same racial or ethnic background, it may be more difficult to interpret each other’s behaviors or emotions based on shared scripts or expectations. This can increase the need for deliberate, effortful mentalizing.
At the same time, the broader literature on intergroup relationships suggests that some individuals—especially those who are secure in their attachment bonds—may be particularly motivated to understand partners from different backgrounds. This dynamic may create both obstacles and opportunities for reflective functioning in interracial romantic relationships. The researchers sought to test how attachment insecurity might interact with relationship type to shape partner reflective functioning in a sample of adults in long-distance relationships.
“We have expertise in interracial couples, partner reflective functioning, and attachment theory independently and this paper was a way of bringing all of those interests together. Partner reflective functioning is a fairly new topic, one that is of particular interest in the context of interracial couples,” said study authors Nicole M. Froidevaux, a postdoctoral scholar at the University of Oregon and Jessica L. Borelli, a professor at the University of California, Irvine.
The study analyzed data from 307 individuals in long-distance romantic relationships, recruited online in 2013. Participants were excluded if they were part of a separate intervention study, if their relationship distance fell outside the specified range, or if key variables were missing. Participants were categorized as being in either an interracial (90 individuals) or intraracial (215 individuals) romantic relationship based on self-reported racial identities of themselves and their partners.
All participants completed a battery of self-report measures, including the widely used Experiences in Close Relationships scale, which assessed levels of attachment anxiety and attachment avoidance. Participants also completed a narrative-based task designed to measure partner reflective functioning. In this task, they were asked to imagine a stressful relationship scenario in which their partner failed to check in after a social event, and then to answer six open-ended questions about the situation.
Their responses were coded by trained raters based on how well participants considered their own and their partner’s mental states, acknowledged ambiguity or opacity in understanding others’ experiences, and linked emotions to behavior. The final reflective functioning score represented an average across all questions and coders.
The results supported the researchers’ predictions, with several notable patterns emerging. First, for both attachment anxiety and avoidance, higher levels of insecurity were associated with lower partner reflective functioning in interracial relationships compared to intraracial ones. However, this effect only appeared at the higher ends of the attachment insecurity spectrum.
In the case of attachment anxiety, individuals in interracial relationships showed significantly lower reflective functioning than those in intraracial relationships only when anxiety levels were at or above the 91st percentile. For attachment avoidance, the difference was more pronounced. People high in avoidance showed a clear drop in reflective functioning if they were in an interracial relationship, but not if they were in an intraracial one.
At the same time, individuals in interracial relationships who were low in attachment avoidance—suggesting higher attachment security—actually demonstrated higher partner reflective functioning than their intraracial peers. This suggests that when individuals are less inclined to distance themselves emotionally or suppress relationship-related distress, they may be more open to exploring and understanding their partner’s mental and emotional landscape.
“We were surprised to find that low attachment avoidance was associated with high partner reflective functioning for individuals in an interracial relationship,” Froidevaux and Borelli told PsyPost. “This finding suggests that low attachment avoidance allows individuals in interracial relationships to thrive by way of broadening their understanding of their partner through curiosity and emotional exploration. We view this as an important and encouraging finding that may help strengthen community support for interracial relationships.”
The researchers note that this pattern highlights both a risk and a potential strength in interracial relationships. On one hand, attachment insecurity may interfere with the emotional work required to navigate cross-cultural dynamics. On the other hand, when individuals feel secure in their relationships, the diversity and complexity inherent in interracial partnerships may prompt them to engage more deeply with their partner’s inner world.
“Our findings help us to understand that being in an interracial relationship may not be inherently difficult, despite common public misconceptions,” Froidevaux and Borelli explained. “While psychologists often emphasize the role of similarity in relationship success, our results highlight that there are also ways that people can bridge differences to build understanding and love for one another. Importantly, we identify attachment avoidance as a psychological factor that may help explain when interracial couples might struggle and when they might thrive.”
While the study provides new insights into the intersection of attachment, race, and mentalizing in romantic relationships, there are some caveats. The data were collected over a decade ago, and social norms and relationship dynamics may have shifted since that time. The sample consisted of individuals in long-distance relationships, which may differ in important ways from geographically close couples.
“An important limitation is that this study did not test our questions over time,” Froidevaux and Borelli noted. “Therefore, we could not test whether one psychological experience came before the other. This is important because sometimes people begin relationships with backgrounds that make their new relationship more challenging while other times they begin to engage in behaviors in their new relationship that make that relationship more challenging. Testing these questions over time will help us understand which one, if any, aspect of the study was important temporally.”
“We would like to test these questions over time, longitudinally, and we would also like to test these questions in a more generalizable sample of individuals. It would also be valuable to investigate whether partner reflective functioning can be enhanced in this population, for example through brief interventions.”
“Relationships are the cornerstone of health and well-being for humans,” the researchers added. “Openness and acceptance of diverse relationships can allow individuals to access partners who they might not otherwise have thought would be a good match for them. We hope that our work and the work of other scientists can continue to elucidate what factors contribute to thriving interracial, interethnic, interfaith, and intercultural relationships around the world.”
