This study extends the investigation of family process models of parental dysphoria and child adjustment, by examining depressive symptoms in both fathers and mothers, and by examining children's representations of family relationships as possible explanatory mechanisms. Participants were 232 children (Time 1 mean age: 5.99; 105 boys, 127 girls) and their cohabiting parents, who participated for three consecutive years. Children's internal representations of multiple family relationships were assessed by means of a story stem completion task. Structural equation modeling indicated that children's inter-parental and attachment representations are part of the process whereby parental depressive symptoms influence child externalizing symptoms. Maternal depressive symptoms also predicted changes in children's representations of marital and attachment relationships over time. The implications for family process models of relations between parental depressive symptoms in community samples and child development are discussed.
