Ninety-four low- and middle-income preschoolers (48 boys, 46 girls) were recruited from two sites in a large southwestern city. Children's positive attributions of peer intent, social problem-solving decisions, and attributions of peers' feelings about the provocation were evaluated from individual interviews. In addition, children's anger perception accuracy and their global emotion situation knowledge were assessed. Teachers and their assistants reported on the children's social competence, internalizing and externalizing behavior, and the degree to which children were physically and relationally victimized. Social competence was a negative predictor of relational and physical victimization, and externalizing behavior was a positive predictor of both types of victimization. Anger perception accuracy was negatively related to physical victimization, and global emotion situation knowledge and attributions of sorrow to provoking peers were positive predictors. Results support a conceptual framework that emphasizes the importance of social and emotion-related social cognitive variables for understanding young children's peer-related victimization.
