The social dimensions of family–peer linkages of 4- to 6-year-old children (N=63) with developmental delays (IQ range, 50–80) were examined in this study. Hierarchical regressions revealed consistent and meaningful patterns of association relating children's influence attempts directed toward their mothers and their interactions with peers. A similar association with peer interactions was found for children's ability to obtain compliance from their mothers. Evidence suggested the existence of a core behavioral pattern that children exhibit with different partners and in different contexts. The role of horizontal forms of parent–child interactions in promoting the peer relationships of children with delays was suggested, particularly in terms of an intervention approach for this group of children.
