In the present research, the influence of racial diversity among classmates and friends on changes in racial self-identification among multiracial youth was examined (n = 5,209; M[subscript age] = 10.56 years at the beginning of sixth grade). A novel individual-level measure of diversity among classmates based on participants' course schedules was…

In this article, I describe a program of research on the psychosocial benefits of racial/ethnic diversity in urban middle schools. It is hypothesized that greater diversity can benefit students' mental health, intergroup attitudes, and school adaptation via three mediating mechanisms: (a) the formation and maintenance of cross-ethnic friendships,…

This study examined the association between ethnicity-related context variables and the prosocial behavior of early adolescents in ethnically/racially diverse schools. Specifically, youths' perceptions of greater representation of same-ethnic peers at school, school support for ethnic diversity, and engagement in and valuing cross-ethnic contact…

This study examined how "homophily" (similarity) and "propinquity" (availability) simultaneously predict both unidirectional and reciprocal cross-ethnic friendships among early adolescents in ethnically diverse classrooms. In a sample of sixth-grade students, liking nominations were used as the indicator of friendship, and both…

This study examined the mediating role of self-blaming attributions on peer victimization-maladjustment relations in middle school and the moderating role of classroom ethnic diversity. Latino and African American 6th grade participants (N = 1105, 56% female) were recruited from middle schools in which they were either members of the numerical…

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…

Recent research suggests that having a mutual antipathy, in comparison to not having an antipathy, is associated with a host of negative outcomes. However, the methods used may not have adequately controlled for rejection and therefore may have provided an incomplete description of the psychosocial correlates of having a mutual antipathy. With a…

An ethnically diverse sample of 6th-grade students completed peer nomination procedures that were used to create subgroups of students with reputations as victims, aggressors, aggressive victims, and socially adjusted (neither aggressive nor victimized). Self-report data on psychological adjustment, attributions for peer harassment, and perceived…

Task involvement and ego involvement were studied in relation to depth of information processing for 126 fifth and sixth graders in 2 experiments. Ego involvement resulted in poorer word recall at deep rather than shallow information processing levels. Implications for the study of motivation are discussed. (SLD)

With a sample of 1,630 sixth-grade students from 77 classrooms, the authors used hierarchical linear modeling to examine how ethnicity within context and classroom social disorder influenced the association between peer victimization and social-psychological adjustment (loneliness and social anxiety). Victimized students in classrooms where many…

To study the effects of motivation on cognition, 55 fifth- and sixth-grade students were randomly assigned to 3 motivational treatment groups: (1) ego-involved (ability oriented); (2) task-involved (mastery oriented); and (3) control (no orientation). The ego-involvement treatment attempted to make subjects feel that their abilities on the tasks…

One thousand twenty-four African American and Latino sixth graders participated in a study examining the moderating role of pubertal development on the relation between peer victimization and adolescent self-worth, depressed mood, and physical symptoms using peer and self-reported victimization. It was hypothesized that early-maturing girls who…
