The purpose of this study was to investigate relationships between children's representations of parent-child alliances (PCA) and their peer relationship quality, using a new scale that was developed to rate representations of PCA in children's family drawings. The parent-child alliance pattern is characterized by a relationship between parent and child that is stronger than the marital relationship. We used family drawings to assess children's (at the ages of 4-8 years) representations of alliances because it is often difficult for children to express their perceptions of family dynamics verbally. Children whose drawings were rated higher in PCA were rated lower in prosocial behavior and assertiveness and higher in social problems by their teachers. These relationships were stronger for boys than for girls.
