Sexual Coercion and Attachment Styles Shape Relationship Satisfaction, Study Finds

The study, titled “Sexual coercion and relationship satisfaction: Dyadic and individual contributions of attachment and dark triad traits,” offers a nuanced view of how personality, power, and intimacy intersect in modern romantic partnerships. Published in Personality and Individual Differences, the findings suggest that women’s relationship satisfaction is influenced primarily by attachment patterns and their partner’s behavior, while men’s satisfaction is more closely tied to experiences of sexual coercion. The results may help inform relationship counseling and interventions aimed at improving communication, reducing coercive behavior, and fostering healthier attachment patterns.

How romantic partners bond emotionally, handle conflict, and respect each other’s boundaries plays a central role in how satisfied they feel in their relationships. The researchers examined how attachment style, dark personality traits, and sexual coercion jointly influence relationship quality, uncovering notable differences between men and women.

The authors frame relationship satisfaction through an evolutionary perspective, describing it as an ongoing assessment of the costs and benefits of remaining with a particular partner. Throughout human history, stable and satisfying relationships increased the chances of successfully raising children, making the ability to evaluate and maintain healthy partnerships an important adaptive trait.

Attachment styles and dark personality traits

Adult attachment theory explains how people manage emotional closeness and the possibility of rejection in intimate relationships. Securely attached individuals generally feel comfortable with intimacy and trust their partners, whereas insecurely attached individuals tend toward anxious or avoidant attachment styles, often experiencing greater stress within relationships.

Anxious attachment is characterized by persistent fear of abandonment and a strong need for reassurance. Avoidant attachment, in contrast, involves discomfort with emotional intimacy and a tendency to withdraw whenever relationships become too emotionally demanding.

The researchers also examined the Dark Triad, a group of socially aversive personality traits. Narcissism is marked by grandiosity and a constant need for admiration. Machiavellianism involves strategic manipulation of others for personal gain. Psychopathy is characterized by impulsivity, low empathy, and a lack of remorse. Previous research has consistently shown that these traits can undermine trust, intimacy, and long-term relationship stability.

Sexual coercion within romantic relationships

Another key focus of the study was sexual coercion, which includes psychological pressure, manipulation, or threats used to obtain unwanted sexual activity from a partner. The researchers examined both experiencing and perpetrating coercion, recognizing that either role can impose significant emotional and relationship costs.

Earlier studies have shown that sexual coercion often occurs alongside other forms of relationship aggression, including emotional abuse and controlling behavior. The researchers therefore wanted to understand how coercion interacts with attachment styles and Dark Triad traits, and whether these relationships differ between men and women.

Large individual survey

The first part of the research involved 848 adults who had been in a romantic relationship for at least one year. Most participants were women. They completed standardized questionnaires measuring relationship satisfaction, attachment styles, Dark Triad personality traits, and experiences of sexual coercion.

Among women, relationship satisfaction was explained almost entirely by attachment style. Higher levels of anxious or avoidant attachment were associated with lower satisfaction. In this individual-level analysis, neither Dark Triad traits nor experiences of sexual coercion significantly predicted women's relationship satisfaction.

The absence of a direct association between women’s satisfaction and sexual coercion mirrors findings from previous relationship research. Some researchers suggest that subtle forms of coercion may be normalized in certain cultural contexts, particularly where traditional gender norms frame controlling behavior as evidence of commitment or care.

The study also explored what predicted sexual coercion itself. Women who reported being victims of sexual coercion were also much more likely to report perpetrating coercive behaviors toward their partners, reflecting a victim-perpetrator overlap observed in other forms of relationship aggression.

Women were more likely to report perpetrating sexual coercion when they scored higher on anxious attachment and Dark Triad traits. According to the authors, intense fears of abandonment combined with manipulative or emotionally detached personality characteristics may lead some women to use sexual behavior as a means of maintaining control or preventing rejection.

Among men in the first study, none of the measured variables significantly predicted relationship satisfaction, victimization, or perpetration of sexual coercion. However, the authors caution that relatively few men participated, limiting the ability to detect meaningful patterns.

Study of real couples

To better understand how these dynamics operate within actual relationships, the researchers conducted a second study involving 55 heterosexual couples. Both partners participated simultaneously through video sessions but completed questionnaires privately, allowing researchers to examine how each person's characteristics influenced both their own and their partner's satisfaction.

Women’s relationship satisfaction was influenced not only by their own attachment style but also by their partner’s characteristics. Women with higher avoidant attachment reported lower relationship satisfaction, consistent with previous research showing that emotional distancing reduces intimacy.

More importantly, women reported lower satisfaction when their male partners displayed anxious attachment, narcissistic traits, or sexually coercive behavior. A partner who combined emotional insecurity with self-centered or coercive tendencies appeared particularly detrimental to women's perceptions of relationship quality.

Men showed a very different pattern. Their relationship satisfaction was not significantly associated with their own attachment style or Dark Triad traits. Instead, their satisfaction was strongly related to experiences involving sexual coercion.

Men reported lower relationship satisfaction both when they were victims of sexual coercion and when they themselves engaged in coercive behavior. Their satisfaction also declined when their female partners displayed coercive behaviors, suggesting that sexual pressure from either direction was linked to poorer relationship quality.

Different pathways to relationship satisfaction

Overall, the findings suggest that women evaluate their relationships through a combination of their own attachment patterns and their partner's emotional and behavioral characteristics. Women appeared especially sensitive to partners who were highly anxious, narcissistic, or sexually coercive.

Men, on the other hand, appeared less influenced by personality characteristics and more affected by concrete relationship experiences, particularly sexual coercion. Any form of coercive sexual behavior within the relationship was associated with reduced satisfaction among male participants.

One particularly interesting finding emerged when comparing the two studies. In the individual survey, women's own reports of sexual coercion were not clearly associated with lower relationship satisfaction. However, when researchers analyzed both partners together, the negative impact of male partners' coercive behavior became much more apparent.

According to the authors, this suggests that relationship dynamics may become clearer when both partners' characteristics are considered simultaneously. It also raises the possibility that some harmful behaviors are minimized or normalized when individuals evaluate their relationships in isolation.

Study limitations

The researchers emphasize several limitations. The first study included substantially more women than men, making conclusions about male relationship dynamics less certain. The second study involved only 55 couples, meaning its findings should be viewed as preliminary.

The participants were also recruited during the COVID-19 pandemic, and couples willing to participate in video-based research may have been relatively well-functioning compared with those experiencing severe relationship distress or abuse. As a result, coercion and conflict may actually be more common than observed in the study.

In addition, most participants were young, educated Brazilians with independent incomes. Cultural beliefs about gender roles, sexuality, and relationships may influence both the occurrence and reporting of coercive behaviors, limiting how broadly the findings can be generalized.

The researchers conclude that larger, more diverse, and cross-cultural studies are needed to determine whether these patterns hold across different societies. They also hope future work will clarify why some women do not appear to associate coercive experiences with lower relationship satisfaction until researchers examine both partners together.
