Maternal Depressive Symptoms and the Growth of Child Executive Function: Mediation by Maternal Sensitivity (Mar, 10.1037/fam0000832, 2021)

This study examined the prospective associations among the trajectories of maternal depressive symptoms, maternal sensitivity, and child executive function (EF) across early and middle childhood, and tested the mediating role of maternal sensitivity in the links between change in maternal depressive symptoms and the growth of child EF. Participants included 1,364 children and mothers from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (NICHD SECCYD). We found that maternal depressive symptoms (from 6 months to Grade 5) and sensitivity (from 36 months to Grade 5) decreased, whereas child EF (planning skills; from Grade 1 to 5) increased over time. We also found several direct associations: (a) lower maternal depressive symptoms at 36 months predicted higher sensitivity at 54 months; (b) higher sensitivity at 54 months and a faster decrease in sensitivity from 36 months to Grade 5 predicted higher child EF in Grade 1; and (c) higher sensitivity at 54 months predicted greater growth of EF from Grade 1 to 5. In addition, two mediation effects were found as follows: Lower levels of maternal depressive symptoms at 36 months predicted both higher levels of child EF in Grade 1 and greater growth of EF from Grade 1 to 5 through higher levels of maternal sensitivity at 54 months. The results suggest that early maternal depressive symptoms may have long-term effects on the growth of EF, especially planning skills, during middle childhood, and that one important pathway that maternal depressive symptoms affect child EF outcomes through maternal sensitivity.
