Objective: Theories about how couples help each other to cope with stress, such as the systemic transactional model of dyadic coping, suggest that the cultural context in which couples live influences how their coping behavior affects their relationship satisfaction. In contrast to the theoretical assumptions, a recent meta-analysis provides evidence that neither culture, nor gender, influences the association between dyadic coping and relationship satisfaction, at least based on their samples of couples living in North America and West Europe. Thus, it is an open questions whether the theoretical assumptions of cultural influences are false or whether cultural influences on couple behavior just occur in cultures outside of the Western world.Method: In order to examine the cultural influence, using a sample of married individuals (N = 7973) from 35 nations, we used multilevel modeling to test whether the positive association between dyadic coping and relationship satisfaction varies across nations and whether gender might moderate the association.Results: Results reveal that the association between dyadic coping and relationship satisfaction varies between nations. In addition, results show that in some nations the association is higher for men and in other nations it is higher for women.Conclusions: Cultural and gender differences across the globe influence how couples' coping behavior affects relationship outcomes. This crucial finding indicates that couple relationship education programs and interventions need to be culturally adapted, as skill trainings such as dyadic coping lead to differential effects on relationship satisfaction based on the culture in which couples live.

A number of studies have described different preference patterns typically found for men and women when choosing romantic mates. These vary according to the involvement level expected in the relationship. Despite the number of investigations on the topic, one must be careful not to generalize because most studies use samples composed of North American university undergraduates. This study sought to determine if the preference patterns typically found in other countries also occur among Brazilian undergraduates. The importance of characteristics and modifications in preference patterns under gradually restrictive conditions was also investigated. In general, the results obtained suggest that the preferences found in a number of countries also occur in Brazil. In short-term relationships, men prioritize physical attributes, whereas personal traits gain importance when involvement increases. Women in short-term relationships value physical and personal traits, whereas in the long term, they emphasize personal characteristics and their mate's desire to acquire resources. Resource-related traits were less important than the other traits, and were more important for women than for men.

There is no consensus whether ideal mate preferences are actually expressed in real choices or whether people choose partners according to traditional sex preferences or seek those similar to them. In order to address these questions, 267 Brazilian university students (120 involved and 147 not involved in a romantic relationship) participated in this study, describing themselves and their current or most recent romantic partner. As inclusion criterion, involved subjects must have been in a stable relationship for at least 12 months. Our results suggest that male choice reflects typical preferences based on Parental Investment Theory. On the other hand, the typical female preferences were not observed; instead, their choices indicate a preference for similar partners to themselves. Given that similarities are important to maintaining long-term relationships, females may adapt their preferences in order to ensure male investment in a long-term relationship.
