The utilization of specific strategies to manage couple conflict has a differential impact on women’s relationship satisfaction. However, considering that women’s role within couple relationship is shaped by societal norms, such association should be examined by embracing a cross-cultural perspective. Thus, the objective of this study is to analyze the effect of individualism/collectivism and masculinity/femininity cultural values on avoidant attachment, perceived conflict solving, and relationship satisfaction. The sample consisted of 334 women from Israel, USA, Türkiye, and Spain. An unconstrained general model elucidates the connections among relationship satisfaction, avoidant attachment, and conflict solving strategies across all countries; yet, the strength of certain associations varies based on the dimensions of masculinity and individualism. In individualistic countries, avoidant attachment predicts lower relationship satisfaction in women. The prediction of own withdrawal by avoidant attachment remains similar among women, regardless of the individualism dimension. Nevertheless, in feminine (i.e., role egalitarian) countries, the link between female’s avoidant attachment and their partner’s use of positive conflict solving strategies is stronger. Additionally, the withdrawal strategy predicts partner demand to a greater extent in women from feminine countries. These findings will assist professionals from different countries in developing culturally sensitive and tailored prevention and intervention tools.
