Maternal depressive symptoms and infant temperament in the first year of life predict child behaviour at 36 months of age

In a longitudinal study, mothers (N=50) self-reported on their depressive symptoms (DS) and their child’s behavior during the first year and at 36 months postpartum. Maternal DS during infancy were associated with child conduct problems (CP), suggesting a long-term association between maternal mental health and the development of child behavior. Infant temperament was also associated with child behavior so that negative affect predicted child CP, while infant surgency was associated with later hyperactivity/inattention. This study contributes to the literature by jointly assessing the role of maternal DS and infant temperament and showing that these are independent predictors of childhood behavior.
