This study describes the use of story stems in order to determine children's representations of relationships with mothers, teachers, and friends, and how these representations are related to mother- and teacher-rated social competence. Thirty preschool-aged children were administered the story stem tasks featuring three different interactional partners, which were then coded for quality of the portrayed relationship. Mothers and teachers were also asked to rate children's social competence. Findings suggest that children generally have similar, but not identical, working models of their relationships with mothers and teachers which are related to internal working models of their relationships with friends. Furthermore, elements of children's narratives about teachers and friends were related to teacher's ratings of children's social competence. Findings from this study demonstrate the dynamic and interactive nature of children's representations of relationships with their mothers, teachers, and friends. (author abstract)
