Developmental cascades from maternal depressive symptoms in childhood to adolescents' friendship quality: A 13-year longitudinal study.

Adolescent friendships of positive quality promote well-being for decades to come. But what impedes the development of positive friendship quality? The present study examined whether maternal depressive symptoms during early childhood predict children's friendship quality into adolescence, and whether observed negative parenting behavior and children's earlier friendship quality, social skills, and their own depressive symptoms in middle childhood mediate these associations. We used six waves of data from a prospective longitudinal community sample (N = 396). The study followed children and their mothers across 13 years from child ages 2-15 years (52% female, 67% White, 26% Black), collecting multi-informant data (from mothers, children, teachers, and behavioral observations). The significance of indirect effects was estimated with structural equation modeling. Exposure to high levels of maternal depressive symptoms in early childhood (child ages 2-5 years) was negatively correlated with children's later adolescent friendship quality (at age 15). Structural equation models revealed that this association was mediated by children's poorer social skills (age 7) and friendship quality (age 10). Negative parenting behavior and children's depressive symptoms did not mediate this association. Maternal depressive symptoms have downstream associations with children's friendship quality into adolescence, including via children's social skills. Promoting the social skills of children exposed to maternal depressive symptoms could have long-term positive effects. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
