LGBTQ+ youth make up a significant portion of the United States student population (Conron, 2020). A sense of belonging for middle school students is an essential indicator for academic achievement and positive motivational and health outcomes (Kosciw et al., 2020; Steiner et al., 2019), yet LGBTQ+ students experience less belonging than their…

The current study examined school variations in academic engagement norms and whether such norms affect those most susceptible to peer influence. We presumed that behaviors associated with perceived popularity make norms salient and are most likely to affect socially marginalized (rejected) youth. Focusing on differences across 26 middle schools,…

This short-term, longitudinal study examines evidence that the level of popularity among adolescents' peer role models exacerbates the emotional impact of mistreatment by peers. We recruited 469 adolescents (255 boys, 214 girls; [X-bar] age = 12.7 years) from an ethnically diverse middle school and followed these youth for a 1-year period. We…

This study examined the influence of academic teaming (i.e., sharing academic classes with the same classmates) on the relationship between social preference and peer victimization among 6th-grade students in middle school. Approximately 1,000 participants were drawn from 5 middle schools that varied in their practice of academic teaming. A novel…

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…

Links among concurrent and longitudinal changes in pubertal development and empathic ability from ages 10 to 13 and neural responses while witnessing peer rejection at age 13 were examined in 16 participants. More advanced pubertal development at age 13, and greater longitudinal increases in pubertal development, related to increased activity in…

This study employs latent class analysis to construct bullying involvement typologies among 3,114 students (48% male, 58% White) in 40 middle schools across the United States. Four classes were constructed: victims (15%); bullies (13%); bully/victims (13%); and noninvolved (59%). Respondents who were male and participated in fewer conventional…

This study examines belongingness as a strengths-based protective factor. Belongingness is investigated in relationship to the threat of low peer acceptance for loneliness and of high loneliness for depression in adolescents. Data were collected from peers for adolescents' peer acceptance and from adolescents themselves for other variables.…

Few after-school programs target alcohol and other drug (AOD) use because it is difficult to encourage a diverse group of youth to voluntarily attend. The current study describes CHOICE, a voluntary after-school program which targeted AOD use among middle school students. Over 4,000 students across eight schools completed surveys and 15%…

This article provides a conceptual account and empirical analyses of the development of "boundary-crossing competence"--the ability to function competently in multiple contexts--using representative cases from two after-school programs with immigrant and low-socioeconomic status students. Our findings suggest that organizational designs…
