Abstract
Problems in mother–child relationships are thought to be key to the intergenerational transmission of depression. To evaluate neural and behavioral processes involved in these pathways, we tested effects of maternal depression and maternal-child relationship quality in early childhood on neural and interviewer-based indicators of social processes in adolescence. At age 3, children and mothers (N = 332) completed an observational parenting measure and diagnostic interviews with mothers. At age 12, adolescents completed a task in which event-related potentials (ERPs) were recorded in response to peer acceptance and rejection feedback and interviews to assess peer stress. Lower mother–child relationship quality at age 3 was associated with enhanced reactivity to rejection, as measured by N1, and greater peer stress at age 12. Indirect effects of maternal depression through mother–child relationship quality were observed for N1 and peer stress. Findings inform understanding of disruptions in social functioning that are likely to be relevant to the intergenerational transmission of depression.
