Children and adolescents spend considerable time online. The current study investigated moderators of short-term longitudinal associations from social media use to changes in body satisfaction and physical activity. Participants (144 girls, 152 boys) were third-sixth grade students (ages 8-13) attending public schools in Florida (USA).…

The goal of this study was to examine the unique associations of aggression with peer status in a non-Western context. The moderating effects of peer community and teacher closeness at the classroom level and gender and grade at the individual level were considered. Participants were 1954 third to sixth grade students (M[subscript age] = 9.60…

Evidence suggests that children's expectations for how their teacher responds to students' aggression moderate concurrent links between peer victimization and adjustment. This study extends this work by examining these associations longitudinally. Youth (N=366; 196 girls; M[subscript age]=9.25years) reported on their teacher's use of five…

Exposure to peer stress contributes to adolescent depression, yet not all youth experience these effects. Thus, it is important to identify individual differences that shape the consequences of peer stress. This research investigated the interactive contribution of cumulative peer stress during childhood (second-fifth grades) and executive…

Worry in adults has been conceptualized as a thinking process involving problem-solving attempts about anticipated negative outcomes. This process is related to, though distinct from, fear. Previous research suggested that compared to adults, children's experience of worry is less strongly associated with thinking and more closely related to fear.…

The purpose of this study was to identify and validate subtypes of peer status by integrating preference and popularity into a single framework. Person-oriented analyses were performed among 3,630 children and adolescents of different cohorts in primary and secondary education. In the young age groups (Grade 3/4 to Grade 7), three clusters were…

Classrooms are unique and complex work settings in which teachers and students both participate in and contribute to classroom processes. This article describes the measurement phase of a study that examined the social ecology of urban classrooms. Informed by the dimensions and items of an established measure of organizational climate, we designed…

This study examined the effects of pubertal status, pubertal timing (actual and perceived), and youth biological sex on symptom dimensions of anxiety (i.e., social, separation, harm avoidance, physical) in African Americans (n = 252; ages 8-12). For girls, results indicated that pubertal status and timing (actual) exerted similar effects for some…

This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and self-esteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in…

Coders used real-time focal-child sampling methods to observe the playground behavior and victimization experiences of 600 third to sixth grade youth. Person-centered analyses yielded three profiles that specified aggressive function (reactive, proactive) and form (direct, indirect), and conformed to social-information-processing functional…

This study had three goals: (a) assessing the predictive association of externalizing and internalizing behaviors during childhood with sexual onset during early adolescence; (b) examining the interactive link of externalizing and internalizing behaviors with early sexual onset; and (c) investigating the moderating effect of gender in this…

This study investigated the independent and interacting effects of classroom-level embeddedness (i.e., hierarchical vs. egalitarian) and classroom density on the perceived popularity and social preference of aggressive and victimized 3rd-4th grade students (N = 881). A cohesive blocking procedure was used to compute embeddedness. Multilevel…

This study examined the relationship between overt and relational peer victimization and depression in a sample of predominantly Mexican American students in Grades 3 through 5 in a Southwestern U.S. school district. Acculturation level was assessed and included as an independent variable along with gender and grade (a proxy for age). Fifty six…

We examined the influence of income source within the context of persistent poverty on children's disruptive classroom behavior at age 12 and whether these associations were mediated by maternal supervision at ages 10 and 11. Using a subsample (N = 1,112) from the Quebec Longitudinal Study, we coded four economic circumstances indicating…

Similarities between adolescents are often the cornerstone of a friendship; yet researchers know little about the similarities in friends' perceptions of the relationship. In the current study, the authors examine similarities in friends' perceived friendship qualities during the transition into early adolescence (n = 77 third graders, 110 fourth…
