“It Must Be Me”: Ethnic Diversity and Attributions for Peer Victimization in Middle School

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 majority ethnic group, the numerical minority, or one of several ethnic groups in ethnically diverse schools. Peer nomination data were gathered in the Fall of 6th grade to determine which students had reputations as victims of harassment and self-report data on self-blame for peer harassment and the adjustment outcomes of depressive symptoms and feelings of self-worth were gathered in the Spring of 6th grade, approximately 6 months later. A mediational model in which self-blame partly explained the relation between victimization and maladjustment was supported among students from the majority ethnic group in their classroom but not among students from the minority group. The usefulness of including ethnic diversity as an important context variable in studies of peer victimization during early adolescence was discussed

Understanding Adolescent Delinquency: The Role of Older Siblings’ Delinquency and Popularity with Peers

The present study examined delinquency concordance and the moderating effects of younger sibling perceptions of older sibling popularity in a sample of 587 adolescent sibling pairs. Using a social learning framework and taking dyad composition into account, perceptions of popularity were hypothesized to strengthen siblings’ concordance for delinquency. Older sibling delinquency significantly predicted younger sibling delinquency. Older sibling popularity was not important in predicting boys’ delinquency. However, perceptions of older sibling popularity directly predicted reduced delinquency for girls with older sisters. A significant interaction effect was found for girls with older brothers. Older brother delinquency predicted girls’ delinquency for girls who perceived their older brother to be relatively popular. There was no delinquency concordance for girls who perceived their older brothers to be less popular

Comparisons of school and home-packed lunches for fruit and vegetable dietary behaviours among school-aged youths.

ObjectiveSchool-based interventions and policies encourage youths to include and consume fruits and vegetables at lunchtime via school lunches, but limited research has examined how these behaviours compare when youths have home-packed lunches. The objective of the present study was to compare fruit and vegetable contents and consumption among students having school or home-packed lunches over the school week.DesignParticipants were observed over five consecutive days at school lunchtime. Trained analysts estimated students' lunchtime fruit and vegetable contents and consumption using digital imaging. Mixed models examined associations between fruit and vegetable dietary behaviours and lunch source (school v. home-packed), controlling for student gender, grade and school.SettingThree elementary schools in northern California, USA.ParticipantsFourth-, fifth- and sixth-grade students (nchildren 315; nobservations 1421).ResultsStudents were significantly less likely to have and to consume fruits and vegetables (all P<0·05) when having home-packed lunches, compared with when having school lunches. Among those who did have or did consume these foods, having a home-packed lunch was associated with consuming significantly less fruit (P<0·05) but no differences for other dietary outcomes.ConclusionsThe study adds to a growing body of literature indicating shortfalls in fruit and vegetable contents and consumption associated with having a home-packed lunch, relative to having a school lunch. Findings suggest that school-based interventions, particularly when targeting home-packed lunches, should focus on whether or not these foods are included and consumed, with less emphasis on quantities

Prospective associations between peer support, academic competence, and anxiety in college students.

Previous literature has demonstrated that peer support is instrumental for the promotion of adaptive academic and mental health outcomes; however, limited research has examined prospective directional associations between peer support and adjustment within college settings. The purpose of this study was to investigate the longitudinal associations between peer support, academic competence, and anxiety among U.S. college students. U.S. students from a diverse 4-year university (N = 251, 75% women, 24% men, and < 1% a different gender) reported on peer support, academic competence, and anxiety using validated questionnaires at two time points (Fall term of sophomore year and Spring term of senior year). Results showed that peer support was positively associated with academic competence over time but was not significantly related to future anxiety. Academic competence did not significantly predict peer support or anxiety over time, but anxiety was associated with lower future academic competence. These findings offer insight into how types of social relationships link with academic motivation and anxiety over time within educational settings

The Utility of Latent Class Analysis to Understand Heterogeneity in Youth’s Coping Strategies: A Methodological Introduction

Latent class analysis (LCA) is a useful statistical approach for understanding heterogeneity in a population. This paper provides a pedagogical introduction to LCA modeling and provides an example of its use to understand youth’s daily coping strategies. The analytic procedures are outlined for choosing the number of classes and integration of the LCA variable within a structural equation model framework, specifically a latent class moderation model, and a detailed table provides a summary of relevant modeling steps. This applied example demonstrates the modeling context when the LCA variable is moderating the association between a covariate and two outcome variables. Results indicate that students’ coping strategies moderate the association between social stress and negative mood, however they do not moderate the social stress-positive mood association. Appendices include R (MplusAutomation) code to automate the enumeration procedure, 3-step auxiliary variable integration, and the generation of figures for visually depicting LCA results
