Memory Fades, But Roles Remain: Gendered Dyadic Coping and Marital Satisfaction Among Chinese Couples Navigating Mild Cognitive Impairment

<b>Background:</b> This study investigates how dyadic coping interacts with gender identity and within-couple gender ideology (dis)similarity to influence marital satisfaction in 202 heterosexual married couples with mild cognitive impairment (MCI). <b>Research Design:</b> We utilized cross-sectional dyadic data and actor-partner interdependence moderation models to examine the interactions between dyadic coping, gender ideology (dis)similarity, and gender identity. <b>Results:</b> The results revealed positive associations between dyadic coping and marital satisfaction for both persons with mild cognitive impairment (PwMCIs) and their spouse care partners (SCPs). Two-way interactions indicated that: (1) the association between a SCP's dyadic coping and their own marital satisfaction was moderated by the couple's gender composition; and (2) the association between a PwMCI's dyadic coping and their own marital satisfaction was moderated by ideological dissimilarity with their spouse. <b>Conclusions:</b> These findings inform culturally sensitive interventions and extend dyadic health theory in non-Western contexts.
