The associations among teacher-student relationships (e.g., close, conflictual, and dependent), peer victimization, internalizing (e.g., sadness, loneliness, and anxiety), and school attitudes (e.g., avoidance, liking) were investigated in a sample of 153 (76 boys and 77 girls) racially diverse (42% Latino and 46% White) third grade students and their teachers (N = 30: 15 T1; 15 T2). Specifically, a two year longitudinal design was used in which data were gathered using self and teacher questionnaires which were administered during the spring of third grade and then a year later when children were in fourth grade. Findings showed that conflictual and overly dependent teacher-student relationships were positively correlated with peer victimization; however, closeness as a quality of teacher-student relationships was not associated with peer victimization, internalizing, school liking, or school avoidance. Support for the hypothesis that teacher-student relationships moderated the relations between peer victimization and internalizing was mixed. Specifically, conflictual teacher-student relationships were found to exacerbate the effects of victimization on internalizing problems whereas no such relationships were found for close or dependent relationships. Taken together, findings from this study offer further evidence that the relationships students form with their teachers, especially conflictual and overly dependent teacher-student relationships, contribute to their psychological development, and may be especially influential for children who are victimized by classmates.
