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.
