Teachers Can Make a Difference in Bullying: Effects of Teacher Interventions on Students' Adoption of Bully, Victim, Bully-Victim or Defender Roles across Time.

School bullying is a serious problem worldwide, but little is known about how teacher interventions influence the adoption of bullying-related student roles. This study surveyed 750 early adolescents (50.5% female; average age: 12.9 years, SD = 0.4) from 39 classrooms in two waves, six months apart. Peer ratings of classmates were used to categorize students to five different bullying-related roles (criterion: >1 SD): bully, victim, bully-victim, defender, and non-participant. Student ratings of teachers were used to obtain class-level measures of teacher interventions: non-intervention, disciplinary sanctions, group discussion, and mediation/victim support. Controlling for student- and class-level background variables, two multilevel multinomial logistic regression analyses were computed to predict students' bullying-related roles at wave 2. In the static model, predictors were teacher interventions at wave 1, and in the dynamic model, predictors were teacher intervention changes across time. The static model showed that disciplinary sanctions reduced the likelihood of being a bully or victim, and group discussion raised the likelihood of being a defender. Mediation/victim support raised the likelihood of being a bully. The dynamic model complemented these results by indicating that increases in group discussion across time raised the likelihood of being a defender, whereas increases in non-intervention across time raised the likelihood of being a victim and reduced the likelihood of being a defender. These results show that teacher interventions have distinct effects on students' adoption of bullying-related roles and could help to better target intervention strategies. The findings carry practical implications for the professional training of prospective and current teachers.

"They Think that I Should Defend": Effects of Peer and Teacher Injunctive Norms on Defending Victimized Classmates in Early Adolescents.

Norms have been suggested as important characteristics of the social-ecological context for defending victimized peers, but little is known about the contribution of student perceived injunctive norms (regarding the appropriateness of defending) imposed by peers and teachers. To investigate the role of these norms in defending, a sample of 751 early adolescents (51% female; Mage at Time 1:13 years) was assessed at two time points. Defending, as measured by peer- and self-ratings, decreased slightly over a six-month timespan. Three-level models (with time, students, and classrooms as the levels) indicated that both individual- and classroom-level perceived peer injunctive norms (but not teacher injunctive norms) had positive effects on defending over time regardless of the source of the information on defending (peers or self). These findings support programs that encourage defending through peer norms.

Effectiveness of the KiVa anti-bullying program in the Czech Republic: A cluster randomized control trial.

AIMS: One of the most widely used evidence-based anti-bullying programs, KiVa, originates from Finland and aims to change students' peer context, activate teachers, and inform parents with two main components (universal preventive actions and indicated actions when bullying occurs), complemented by monitoring. Because research documented somewhat varied KiVa outcomes in different countries and because there is a lack of research focusing solely on the effectiveness of the universal and indicated actions, this study aimed to evaluate the effectiveness of KiVa main components when implemented in a new country. This two-arm parallel cluster randomized control trial (RCT) evaluated the effectiveness of the KiVa anti-bullying program in elementary schools in the Czech Republic. It examined the effects of the universal and indicated actions on self-reported bullying and victimization as primary outcomes and well-being as a secondary outcome, while keeping monitoring constant across the intervention and control schools. The study also examined the role of implementation fidelity on the proposed outcomes. METHODS: Schools were allocated via stratified randomization into a KiVa intervention group (12 schools, 35 classes, N = 407 students) or a wait-list control group (12 schools, 32 classes, N = 400 students). The study employed data from baseline and post-measurement waves, which were 10 months apart. RESULTS: The data were analyzed using linear mixed effects models, which showed no significant intervention or fidelity effects for bullying, victimization, and well-being. However, promising trends (at α < .10) were revealed, such as lower levels of bullying observed in the intervention group and in schools with high implementation fidelity. Additional analysis using Bayes factors supported these promising trends and provided moderate support for lower levels of victimization in the intervention group compared to the control schools. CONCLUSIONS: Evaluation of effectiveness of anti-bullying programs could benefit from a more targeted fidelity assessment at the classroom or individual level and from distinguishing between the effects of the main components of the programs and the effects of monitoring. The promising yet non-significant intervention and fidelity effects suggest that schools may require enhanced support and longer implementation time frames than a single school year, especially when implementation faces structural obstacles, such as the Covid-19 pandemic.

An experimental study of teachers' evaluations regarding peer exclusion in the classroom.

BACKGROUND: While research has documented negative social and academic consequences that occur when students experience peer exclusion, few studies have been conducted to investigate teachers' evaluations of peer exclusion. AIMS: This study investigated whether ethnic and gender biases enter teachers' evaluations of classroom peer exclusion that met criteria for bullying. SAMPLE: Teachers (N = 740; 77% female) of early and middle adolescents participated in the study. Participants were recruited from 118 elementary and secondary schools across the Czech Republic. METHODS: Using a between-subjects design, teachers evaluated a scenario of classroom peer exclusion initiated by majority ethnic (Czech) students. The scenarios varied contextual characteristics: target's ethnicity (majority Czech vs. minority Arab), target's gender, and excluders' gender. RESULTS: Analyses revealed several subtle contextual effects. Although teachers viewed exclusion as having a more negative impact for the fair treatment of Arab targets than for Czech targets, their reasoning about the wrongfulness of such exclusion was less focused on the moral concerns about fairness for Arab than for Czech targets. In contrast to girl targets, teachers were less concerned about the harmful impact on exclusion for boy targets when considering intervention. Excluders' gender had significant interactions with the target's gender on reasoning about wrongfulness of exclusion and the target's ethnicity for viewing exclusion as impairing the target's academic engagement. CONCLUSIONS: The findings of subtle ethnic and gender biases underscore the need for research on teacher perspectives on peer exclusion and for training teachers how to address peer exclusion in the classroom across various contexts.

Victimization and its associations with peer rejection and fear of victimization: Moderating effects of individual-level and classroom-level characteristics.

BACKGROUND: Past research has shown that peer victimization by bullying is associated with peer rejection and fear of victimization, but little is known about the interplay between victimization and other characteristics in the prediction of these experiences. We assume that the associations between victimization and peer rejection/fear of victimization are moderated by multiple characteristics, including aspects of peer ecology. AIMS: The study tested whether the links between victimization and peer rejection/fear of victimization are moderated by gender, peer support, and two features of classroom peer ecology: classroom victimization rate and classroom hierarchy (the variability of popularity among students). SAMPLE: The sample included 512 early adolescents attending sixth grade retrieved from 25 elementary school classrooms. METHODS: Participants completed a set of self-report and peer nomination instruments in classroom settings. RESULTS: Multilevel linear modelling showed that higher levels of peer rejection were associated with higher victimization, male gender, and lower peer support. The association between victimization and peer rejection was attenuated for females and when the classroom victimization rate was higher. A higher fear of victimization was related to higher victimization, female gender, lower peer support, and a higher classroom victimization rate. The link between victimization and fear of victimization was strengthened by female gender and higher levels of classroom hierarchy. CONCLUSIONS: The results indicate the relevance of the interplay between victimization and gender and between victimization and classroom peer ecology in understanding peer rejection and fear of victimization.
