Peer relationships are a significant factor in the lives of most children especially in middle childhood. Previous studies certainly found that peer relationships were associated with the child-mother relationships. However, researcher indicated that children are also particulaly attached to their father especially in middle childhood (Papalia & Olds, 1998). In Thailand, fathers are increasingly becoming important caregivers as the number of working mothers increase. Thus, this study examined the association between the daughter-father relationship and the quality of the daughter's relationships to her close peers.
