Nilüfer Kafescioğlu, with scholars from Kadir Has University and University of Akureyri examines the actor–partner effects of attitudes toward group-based inequality, as measured by social dominance orientation (SDO), on marital quality, and the indirect actor–partner effects of SDO on marital quality via ambivalent sexism and partners’ perceptions of their own relationship power. Previous research has suggested that social attitudes may influence relationship dynamics, but it remains unclear whether broader views on social inequality can impact marital quality between partners. 

In this study, 90 heterosexual married couples in Turkey (N = 180) participated in an online survey measuring SDO, marital quality, relationship power, and ambivalent sexism. The actor–partner interdependence model (APIM) and actor–partner interdependence model of mediation (APIMeM) were used to analyze both direct and indirect actor–partner effects. 

The results indicated that for indirect effects, men’s SDO negatively influenced their marital quality through relationship power and hostile sexism. For women, no significant indirect effects were identified. However, women’s relationship power was positively associated, and their benevolent sexism negatively associated, with both their own and their partners’ marital quality.

These findings contribute to a more integrated understanding of the connections between political, social, and personal factors in individuals’ lives. The study underscores the importance of exploring how men’s and women’s views on social inequality affect their intimate relationships, offering insights for clinical practice and relational education
