<p>Previous research has found that heterosexual women’s perceptions of their male partners’ conformity to traditional masculine norms are negatively related to their relationship satisfaction. In this study, we extended extant research by examining women’s self-silencing and relationship power as mediators of this association among a sample of 338 young adult women. Masculine norms of playboy, power over women, winning, emotional control, and self-reliance were significantly correlated with relationship satisfaction at the bivariate level, while only playboy significantly predicted relationship satisfaction in a multiple regression model. Self-silencing and relationship power significantly mediated the associations between two masculine norms (playboy and power over women) and relationship satisfaction. Further, self-silencing mediated the association between self-reliance and relationship satisfaction. Our findings suggest that women’s relationship satisfaction may be improved by feminist therapeutic interventions targeting both women and men’s traditional gendered socialization.</p>
