RESUMEN
This mixed-methods research study aimed to assess the contribution of interparental relationship quality and paternal support for mothers to maternal mental health among Black parents in a metro area characterized by severe racial disparities. We also explored Black parents' understanding of meaningful paternal support for mothers. Using survey data collected from Black mothers (N = 75), we examined correlations among the study variables, then conducted mediation and moderation analyses to examine whether relationship quality would mediate the association between paternal support and maternal mental health and to test whether relationship quality would moderate the association between paternal support and maternal self-reported overall health. We used inductive thematic analysis to analyze data from focus groups with Black parents (N = 15). We found that mothers' mental health was positively correlated with relationship quality, mothers' subjective health was positively correlated with paternal support, and relationship quality significantly mediates the relationship between paternal support and maternal mental health while controlling for relationship status. Our thematic analysis yielded four themes to characterize meaningful paternal support for mothers and a high quality interparental relationship: (1) Teammates; (2) Multidimensional, everyday support; (3) Communication is key; and (4) Challenge racism and disrupt intergenerational trauma. Findings suggest that paternal support and interparental relationship quality can play a protective role, promoting maternal mental health and wellbeing. Providers of perinatal services should support Black parents to support one another, including as advocates in confronting racism.
