Few studies have examined how different characteristics of maternal depression may be associated with developmental outcomes among low-income children. The current study prospectively examined whether the timing (pregnancy vs. early postpartum), severity, and chronicity of maternal depression were associated with child cognitive and social-emotional development in two cohorts of primarily low-income Latinx immigrant mothers and their children. Maternal depression was assessed during pregnancy and at 6 months postpartum. Child development was assessed up to 5 years postpartum. Results showed that maternal depression experienced during pregnancy was associated with lower child cognitive development, particularly among girls. Additionally, both the timing (pregnancy and early postpartum) and severity/chronicity of maternal depression were each independently associated with lower child social-emotional development. These findings highlight the need for early prevention interventions to help offset the adverse effects of maternal depression on child developmental outcomes in this at-risk population.
