Marital conflict and parental hostility: Links with children's sibling and peer relationships.

The authors examined the associations between marital conflict and children's relationships with siblings and peers. Mothers' and fathers' hostility toward children and children's interpretations of parents' marital conflict (self-blame and feeling threatened) were investigated as mediators between marital conflict and children's sibling and peer relationships. The sample included 136 intact 2-child families. Children were 7 and 10 years old. Data were collected from observations of marital and family interaction and from family members' reports. Results showed that marital conflict was associated with problematic sibling and peer relationships. Both maternal and paternal hostility mediated the associations between marital conflict and sibling relationships. The link between marital conflict and sibling rivalry was also mediated by children's feelings of self-blame for their parents' conflict. Fathers' hostility toward children mediated the association between marital conflict and children's problematic peer relationships.
