Racism is a multifaceted system of oppression that disproportionately harms Black mothers and children across the lifespan. Despite reliable evidence that racism is associated with worse mental health outcomes (eg, increased depressive symptoms), less is known about potential intergenerational effects of Black mothers’ experiences of racism on children’s mental health, as well as how traumatic experiences influence these pathways. In this cross-sectional quantitative study, we aimed (1) to replicate the finding that maternal experiences of racism are associated with both maternal and child depression; (2) to identify whether maternal experiences of racism are indirectly associated with child depression via the effect of maternal depression; and (3) to test whether the indirect effect of racism on child depression via maternal depression is conditioned on maternal trauma.
Black mothers and their children (N = 148 dyads) were recruited from an urban hospital and were interviewed about their experiences of racism, trauma, and mental health symptoms. The mothers’ average age was 35.16 years (SD = 8.75) and the children’s average age was 10.03 years (SD = 1.51).
First, we found that maternal experiences of racism were associated with more severe maternal depression (r = 0.37, p < .01) as well as more severe child depression (r = 0.19, p = .02). Second, we found that maternal experiences of racism were indirectly associated with child depression through the effect of maternal depression (ab = 0.76, 95% CI = 0.26, 1.37). Third, we found that maternal trauma exposure moderated this indirect effect such that, at relatively lower levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was nonsignificant (ωlow = −0.05, 95% CI = −0.50, 0.45), whereas at relatively higher levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was statistically significant (ωhigh= .65, 95% CI = 0.21, 1.15).
These findings suggest that the indirect effect of maternal experiences of racism on child depression through the effect of maternal depression depends on the degree of maternal trauma exposure. This study advances the literature by shedding light on key processes that can explain the intergenerational effects of racism as well as contextual factors that can exacerbate racism’s downstream consequences across generations.
