The relations between peer harassment, psychological adjustment, and school functioning were investigated with an ethnically diverse sample of middle school students. A conceptual model, which proposed that self-perceived peer harassment predicts psychological adjustment (loneliness, depression, and self-worth), which in turn predicts school outcomes (GPA and attendance), was tested using concurrent data (n = 244). Structural equation modeling supported the proposed model. Longitudinal analyses with a subsample (n = 106) of students revealed that subjective self-views of victimization were moderately stable across a 1-year period. Comparisons across stable and unstable victim groups suggested that concurrent (rather than earlier or chronic) perceptions of victimization predicted loneliness and selfworth. Finally, changes in subjective perceptions of victimization, self-worth, and loneliness across the 1-year period predicted subsequent GPA, absenteeism, and teacher-rated social adjustment. Findings are discussed in terms of the short-and long-term effects of peer harassment.

This study uses latent class analysis (LCA) to empirically identify victimization groups during middle school. Approximately 2,000 urban, public middle school students (mean age in sixth grade = 11.57) reported on their peer victimization during the Fall and Spring semesters of their sixth, seventh, and eighth grades. Independent LCA analyses at each semester yielded 3 victim classes based on victimization degree rather than type (e.g., physical vs. relational). The most victimized class always represented the smallest proportion of the sample, decreasing from 20% in sixth grade to 6% by the end of eighth grade. This victimized class also always reported feeling less safe at school concurrently and more depressed than others 1 semester later, illustrating the validity of the LCA approach.

Students' perceptions of their safety and vulnerability were investigated in 11 public middle schools (more than 70 sixth-grade classrooms) that varied in ethnic diversity. Results of hierarchical linear modeling analyses indicate that higher classroom diversity is associated with feelings of safety and social satisfaction. African American (n= 511) and Latino (n= 910) students felt safer in school, were less harassed by peers, felt less lonely, and had higher self-worth the more ethnically diverse their classrooms were, even when controlling for classroom differences in academic engagement. Results at the school level were similar to those at the classroom level; higher ethnic diversity was associated with lower levels of self-reported vulnerability (but no difference in self-worth) in both fall and spring of sixth grade. In the spirit of Brown v. Board of Education, the current findings offer new empirical evidence for the psychological benefits of multiethnic schools.

This study examined associations among peer victimization, psychosocial problems, physical symptoms, and school functioning across the 1st year in middle school. An ethnically diverse sample of urban 6th graders (N=1,526) reported on their perceptions of peer victimization, psychosocial adjustment, and physical symptoms during fall and spring. Objective measures of school functioning (i.e., grade point average and absences) were also collected. In Model 1, peer victimization in the fall was associated with spring psychosocial maladjustment and physical symptoms, which in turn predicted poor spring school functioning. Model 2 suggested that psychosocial difficulties increase the risk of victimization, although physical symptoms did not predict victimization. No sex or ethnic group (African American, Asian, European American, and Latino) differences were found in the model structure or the strength of the path coefficients for either model, suggesting that the process is the same for boys and girls and students from different ethnic groups.

Two studies examined daily incidents of peer harassment in urban middle schools. Sixth-grade students (M age = 11 years) described their daily personal experiences and witnessed accounts of peer harassment, and rated their negative feelings across a 2-week period. In Study 1 (n = 95), within-subject analyses across 4 days revealed that both personally experienced and witnessed harassment were associated with increases in daily anxiety, whereas witnessing harassment buffered students against increases in humiliation on days when they personally experienced harassment. Evidence for witnessing as a buffer against increases in humiliation and anger was also found in Study 2 (n = 97) that included 5 daily reports. Witnessing harassment also protected students against increases in negative self-perceptions.
