The authors investigated relationships among internal representations, empathy, and affective and cognitive processes in fantasy play to test the validity of the Social Cognition and Object Relations Scale Q-Sort (SCORS-Q; D. Westen, 1995) with children. Eighty-six 8-10-year-olds were administered 8 Thematic Apperception Test cards, a standardized play task, and a self-report empathy measure. Teachers rated children's empathy and helpfulness. As predicted, internal representations were related to empathy, helpfulness, and quality of fantasy play. Developmental differences on the SCORS-Q were consistent with object relations theory and with results from the original SCORS. The findings support the value of internal representations as a means of understanding children's interpersonal functioning and contribute to the validity of the SCORS-Q for use with children.
