The Longitudinal Impact of Pre- and Postnatal Maternal Depression and Anxiety on Children's Cognitive and Language Development.

We investigated the longitudinal associations among maternal pre- and postnatal depression, maternal anxiety, and children's language and cognitive development followed from 15 to 61 months. Furthermore, we assessed the protective role of children's early print experiences with books against the adverse effect of maternal depression on language development. Data for mothers and children (51.7% boys, 95% White, N = 11,662) were from the Avon Longitudinal Study of Parents and Children. Prenatal maternal depression held an adverse association with child language (β = −.16, p =.002). Moreover, the risk was greater for girls than boys (β =.19, p =.02). In addition, prenatal depression was significantly and negatively associated with child verbal intelligence quotient (β = −.11, p =.02) and performance intelligence quotient (β = −.12, p =.01). In contrast, postnatal depression or anxiety were not unique predictors of child outcomes. Importantly, children's early experiences with books, as measured by the reported frequency of parent–child shared reading, moderated the negative association between maternal depression and child language development (β =.30, p <.001). Although modest in size, these findings inform models of child risk and resilience related to maternal psychopathology. The results also have implications for clinical programs as well as for prevention and intervention studies focusing on at-home early literacy. Public Significance Statement: This study highlights the adverse impact of maternal mental health, particularly prenatal depression, on children's cognitive and language development. The findings also suggest that reading to children and children's access to books protect them against this adverse effect. Parents should be encouraged to read to their children and help them access books. This simple solution may help lessen some of the harmful effects of maternal depression on child language development. [ABSTRACT FROM AUTHOR]
