Classroom‐ and School‐Level Contributions to Bullying and Victimization: A Review

School bullying is increasingly viewed by researchers as a group phenomenon that extends beyond the perpetrator–victim dyad and is embedded in the wider social context. This paper reviews the literature on classroom and school factors contributing to bullying and victimization among children and adolescents. Considerable variability in the prevalence of these problems exists between classrooms and schools, which are highly relevant contexts for students' social development. Along with individual characteristics, both classroom‐ and school‐related factors explain the bullying dynamic. The contexts may also exacerbate, or buffer against, the effects of individual‐level risk for bullying involvement and the consequences of victimization. We discuss findings on the contributions of demographic and structural characteristics (e.g. grade level, classroom and school size), peer contextual factors (e.g. status hierarchy, group norms and bystander behaviours) and the role of teachers. Finally, implications for research and school‐based antibullying programs are considered. Copyright © 2014 John Wiley & Sons, Ltd.     

Understanding Factors Associated with Bullying and Peer Victimization in Chinese Schools Within Ecological Contexts

We review factors associated with school bullying and peer victimization in the People’s Republic of China (hereafter referred to as China) within the context of Bronfenbrenner (Am Psychol 32:513–531, 1977) ecological systems framework. Bullying and peer victimization are serious problems in Chinese schools, which calls for effective school-based bullying prevention and intervention strategies. However, understanding of this phenomenon has been limited because the majority of the empirical studies have examined individual characteristics (e.g., age, gender), and relatively few Chinese researchers have considered various contexts of the social ecology, such as cultural contexts. We first discuss the definition and prevalence, which is followed by a review of socio-demographic and ecological factors (micro-, meso-, exo-, and macrosystem) that are correlated with school bullying and peer victimization in Chinese schools. Findings from our review suggest that factors at the socio-demographic (age, gender, behavioral/mental health problems), micro- (parents, peers, and teachers), meso- (parents’ involvement in children’s school), exo- (mass media), and macrosystem (emphasis on academic achievement and collectivism vs. individualism) levels can foster or mitigate bullying and peer victimization among children and adolescents in Chinese schools. We then draw implications for assessment, practice, and policy concerning school bullying and peer victimization in China.

Is school bullying really on the rise?

Whether bullying in schools is increasing, as is widely believed, was investigated drawing upon empirical studies undertaken in a wide range of countries in which findings had been published describing its prevalence at different points in time between 1990 and 2009. Results do not support the view that reported bullying in general has increased during this period; in fact, a significant decrease in bullying has been reported in many countries. However, there are some indications that cyber bullying, as opposed to traditional bullying, has increased, at least during some of this period. The reported decreases in the prevalence of school bullying are consistent with reports of significant but small reductions in peer victimisation following the implementation of anti-bullying programs in schools world-wide.     

Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized,effectiveness trial

Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated “real-world” implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.     

社会网络视角下儿童青少年同伴关系网络与欺凌相关行为的共同变化关系

欺凌是一种群体动态过程,同伴生态是欺凌发生发展的重要情境。虽然已有研究重视影响欺凌的同伴因素,但从群体动态关系视角细致探讨欺凌相关行为(欺凌、受欺凌和保护行为)发展变化的研究仍十分有限。从社会网络与欺凌相关行为相互影响的关键问题入手,重点考察欺凌相关行为在同伴关系网络中的发展进程,揭示了同伴关系网络的结构特征和内部关系作为欺凌相关行为是否发生、如何发展的重要生态标志,阐明了存在相同行为特征的个体分群汇聚的选择效应和群体内行为传染的影响效应。未来研究应结合多维社会网络、多类型网络结构和关系特征、不同欺凌角色以及我国本土化特点等进一步加强欺凌治理的群体生态研究,从而更好地为群体生态层面上的欺凌治理提供科学依据。     

Preventing School Bullying: Investigation of the Link between Anti‐Bullying Strategies,Prevention Ownership,Prevention Climate,and Prevention Leadership

School bullying has been a major health and safety concern for teachers and students, which calls for effective strategies to address the issue. In this study, we explored individual and organisational factors that improve the effects of teachers’ use of anti‐bullying strategies in reducing or preventing student bullying. Specifically, we examined the moderating role of teachers’ psychological ownership of their school's anti‐bullying system in the relationship between teacher‐reported use of anti‐bullying strategies and student‐reported bullying incidents. We also investigated how principals’ bullying prevention leadership, rated by a group of directors who are the immediate subordinates of these principals, inspires teachers’ psychological ownership of their school's anti‐bullying system through building teachers’ shared perceptions of a bullying prevention climate. Results of multilevel analyses of multisource data from 2,123 teachers, 407 directors, and 15,967 students in 110 junior and senior high schools indicated that the impact of teacher‐reported use of anti‐bullying strategies on student‐reported bullying incidents was strengthened when teachers have a high level of psychological ownership of their school's anti‐bullying system. Further, principals’ bullying prevention leadership was significantly positively related to teachers’ psychological ownership of their school's anti‐bullying system through teachers’ shared perceptions of a bullying prevention climate.     

Weight,Perceptions, and Bullying: What Kind of Pounds Matter?

A great deal of research has investigated weight as a predictor for bullying victimization. However, weight is rarely examined in light of its potential role in explaining bullying perpetration, despite the fact that the definition of bullying typically requires a power imbalance, which can refer to either social power or physical size. Using negative binomial regressions, we investigated weight as a predictor of overt and relational bullying behaviors for a sample of 3208 6th–8th graders from 11 schools in a northeastern state. We examined whether this relationship differs by gender, and we explored whether objective size or perception of size is more predictive of perpetration. We also examined whether certain protective factors, like a positive school environment, moderated the effect of weight on bullying perpetration. We found that students who reported a higher BMI engaged in more overt, but not relational, bullying perpetration. Interestingly, students with misperceptions about their weight reported higher levels of both types of bullying perpetration, while students reporting a more positive school climate engaged in less overt and relational bullying. We also found gender differences in that girls are statistically more likely to commit overt bullying if they have a higher BMI. Our results suggest that prevention programs should address weight as a predictor of bullying behaviors, especially for girls, but also that body image and misperception of weight are important topics for prevention programs.     

Understanding and Combating School‐Based Bullying From an Individual‐Level Perspective: A Review

Bullying is an ongoing problem in our schools with a significant psychological impact on young people. Despite evidence that school‐based bullying is related to a range of individual, social and environmental factors, the majority of interventions are focused on a “whole of school” approach. Whole‐school interventions have been shown to be successful in reducing rates of bullying, but it is argued that a focus on individual factors, specifically those that are amenable to change, will add to these “whole of school” effects. It is argued that interventions that target factors such as internalising symptoms, externalising behaviours, friendship quality and self‐esteem will help children to build resilience against the bullying behaviours of their peers, and further reduce the incidence of bullying, when applied both at a preventative and treatment intervention level.     

Bullying and victimisation in Scottish secondary schools: Same or separate entities?

Previous research has suggested that bullying is an increasingly severe problem in schools. Such research has approached the phenomenon from two different angles. Earlier research has treated bullying and victimisation as separate entities. However, current research suggests that bullies and victims engage in a special dynamic and interactive relationship, thereby providing the need for studying any similarities and differences between bullies and victims in relation to various factors. The present research has approached bullying and victimisation in both ways. First, we studied differences between bullies, victims, and those not involved in relation to various demographic, school, well‐being, and personality factors to identify factors that separate these three groups. In addition, we studied differences between those involved in bullying/victimisation (one group) and those never involved in relation to the same aforementioned factors to highlight aspects of the development of their special relationship (i.e., common factors). Prevalence rates and types of bullying/victimisation experienced/expressed in Scottish schools were also investigated. It was found that bullying and victimisation, when treated as separate entities, differed in relation to peer self‐esteem, with bullies reporting higher levels of peer self‐esteem than victims. When bullies and victims were treated as one group (involved), they were found to differ from the noninvolved group in relation to various factors, including school, well‐being, and personality factors. The involved group was found to be disadvantaged in relation to all measures used. However, overall results indicated that from all these factors the best predictors of overall involvement as bully, victim, or bully‐victim were Quality of School Life and school stress. The present results support the notion that bullying and victimisation could be treated, by future research, as both separate and/or interactive entities. This is so because bullying and victimisation were found to differ in relation to one personality factor, that is, peer self‐esteem. However, Quality of School Life and school stress, both school factors, were found to be associated with the phenomenon as a whole. Results are discussed in relation to future development of antibullying policy in Scottish schools.Aggr. Behav. 28:45–61, 2002. © 2002 Wiley‐Liss, Inc.     

Protective Factors as Moderators of Risk Factors in Adolescence Bullying

The present study examined the role played by protective factors in moderating the effects of risk factors over bullying and victimization in a sample of 679 male adolescents recruited in Italian high schools. Boys’ involvement in bullying revealed that one in three students has bullied others at least sometimes in the previous three months, and one in six has been victimized at the same rate; victimization decreases with age. The family related risk factor (conflicting parents) was positively associated with bullying and with victimization (together with punitive parenting); the same applied for risk factor related to the individual ways of dealing with problems (emotionally oriented coping skills). Protective factors related to the family context (supportive and authoritative parents) and to the individual (problem solving coping skills) were negatively associated to bullying and victimization. Hierarchical regression analyses revealed a moderating effect of supportive parenting on punitive parenting and on emotionally oriented coping strategies in predicting victimization. Problem solving coping strategies helped buffer the negative impact of emotionally oriented coping strategies over bullying. Implications of results for practitioners and for future studies are addressed.     

The Nature of School Bullying and the Effectiveness of School-Based Interventions

School bullying has become a topic of public concern and considerable research in various countries around the world in the last two decades. We summarise characteristics such as types and causes of school bullying, based on findings from various studies. We further review a variety of large-scale, school-based intervention programmes, implemented in different countries and school settings, that have been systematically evaluated. These programmes have varied substantially in their effectiveness in reducing levels of bullying at schools. Reasons for these mixed outcomes are discussed, together with suggestions for improving the effectiveness of future interventions.     

Like Father,like Child: Early Life Family Adversity and Children’s Bullying Behaviors in Elementary School

Family adversity has been associated with children’s bullying behaviors. The evidence is, however, dominated by mothers’ perceptions of the family environment and a focus on mothers’ behaviors. This prospective population-based study examined whether children’s bullying behaviors were associated with mother- and father-reported family adversity, assessed before and after child birth. Peer-nominations were used to assess bullying behaviors of 1298 children in elementary school (mean age 7.5 years). The following paternal risk factors were prospectively associated with children’s bullying behaviors: (1) father-reported prenatal family distress, (2) fathers’ hostility at preschool age, and (3) fathers’ harsh disciplinary practices at preschool age, but effect sizes were relatively small. The effect of maternal risk factors was less consistent, only mother-reported family distress in childhood was associated with children’s bullying behaviors. The associations were independent of background family risk factors (i.e., life stress, contextual factors, and other background factors such as parental education and risk taking record) and early childhood externalizing problems. Moreover, our results indicated that father-reported family adversity predicted children’s bullying behaviors over and above the background family risk factors, early childhood externalizing problems and mother-reported family adversity. We also demonstrated that the association of fathers’ prenatal hostility and family distress with subsequent bullying behavior of their child at school was partly mediated by fathers’ harsh disciplinary practices at preschool age. Our findings highlight the importance of fathers’ behaviors in the development of children’s bullying behaviors.     

Exploring Adolescents’ Talk About Bullying on an Online Message Board: Broadening and Complicating Understandings of Victimization

Current definitions of bullying, crafted by policymakers and researchers, raise questions about the ways in which adult constructions of bullying reflect, or fail to reflect, the lived realities of adolescents. In particular, the narrow scope of “bullying,” as currently defined, may over-simplify adolescents’ experiences with relational aggression, which often sit in the space between bullying, discrimination, and harassment. This study investigates adolescents’ talk about bullying on an online message board, as one effort to better understand whether adolescents’ constructions of bullying are aligned with those of researchers and policymakers, and where these youth constructions may overlap with ideas about discrimination and harassment. Conducting a content analysis of data from an online, teen message board, we find that participants frequently use the term bullying to describe adult or familial aggression, and often describe bullying behaviors in ways that reflect elements of discrimination and harassment. We conclude with suggestions for future research and practical approaches that might better bridge gaps between research and practice.     

BULLY PREVENTION IN POSITIVE BEHAVIOR SUPPORT

Bullying behaviors are a growing concern in U.S. schools. We present here a behavioral approach to bully prevention utilizing a schoolwide intervention. Bully prevention in positive behavior support (BP‐PBS) teaches students to withhold the social rewards hypothesized to maintain bullying. A single‐subject multiple baseline design across 6 students and three elementary schools was implemented in an empirical evaluation of the intervention's effectiveness. Results indicated that implementation was functionally related to decreased incidents of bullying for all 6 students observed. In addition, we observed a decrease in the social responses from victims and bystanders. Finally, school staff implemented the program with a high degree of fidelity and rated the program as effective and efficient. Limitations and implications of these results are discussed.     

Bullying Behaviors and Victimization Experiences Among Adolescent Students: The Role of Resilience

The role of resilience in the relationship between bullying behaviors, victimization experiences, and self-efficacy was examined. Participants were 393 (191 young men, 202 young women) adolescents (M age = 15.88 years, SD = 0.64 years) from schools in Coimbatore, India, who completed scales to assess bullying behaviors and victimization experiences, resilience, and self-efficacy. Multigroup structural equation modeling, with separate groups created according to participant gender, revealed that resilience mediated the relationship between bullying behaviors and self-efficacy in young men. Young men engaged in bullying behaviors and experienced victimization more frequently than young women. The findings of the study have implication for designing intervention programs to enhance resilience among adolescents and young adults to enable them to manage bullying behaviors.

Profiles of Student Perceptions of School Climate: Relations with Risk Behaviors and Academic Outcomes

School climate has been linked to a variety of positive student outcomes, but there may be important within‐school differences among students in their experiences of school climate. This study examined within‐school heterogeneity among 47,631 high school student ratings of their school climate through multilevel latent class modeling. Student profiles across 323 schools were generated on the basis of multiple indicators of school climate: disciplinary structure, academic expectations, student willingness to seek help, respect for students, affective and cognitive engagement, prevalence of teasing and bullying, general victimization, bullying victimization, and bullying perpetration. Analyses identified four meaningfully different student profile types that were labeled positive climate, medium climate‐low bullying, medium climate‐high bullying, and negative climate. Contrasts among these profile types on external criteria revealed meaningful differences for race, grade‐level, parent education level, educational aspirations, and frequency of risk behaviors.     

Risk and protective factors at school: Reducing bullies and promoting positive bystanders' behaviors in adolescence

Identifying protective factors present at schools located in neighborhoods with high structural violence is fundamental to help prevent the perpetuation of violence . Therefore, the aim of this study was to observe how some school micro‐system variables, such as school environment and interpersonal relationships that adults establish with adolescents, may lead to bullying behaviors or, on the contrary, to positive bystander behavior in the bully‐victim dynamic. The sample was composed of 5,774 adolescents from 71 schools located in violent neighborhoods in Lima (Peru). 31.9 per cent of the sample experienced verbal violence and the prevalence of cyberbullying was 24.6%. Boys were more prone to experience both types of bullying than girls, although no differences were seen in the probability of becoming aggressors during early and late adolescence. The protective model showed that a positive atmosphere based on a supportive environment with clear rules encouraged adults at school to show more support and to provide more orientation in bullying situations, thus promoting a positive bystander behavior between peers. Opposite results were observed in the risk model. Actions at the micro‐system school level are discussed to enhance protective factors and reduce risk factors.     

Person–Group Dissimilarity in Involvement in Bullying and Its Relation with Social Status

This study tested a person-group dissimilarity model for the relation between peer preference on the one hand, and bullying and victimization on the other. This model accounts for both individual and group (i.e., classroom) factors and postulates that children will be rejected by their peers when they display behaviors that deviate from the group norm. We tested the model in a sample of 2,578 early adolescents in 109 middle school classrooms. Multilevel analysis was used to account for our nested data when examining individual and group effects simultaneously in cross-level interaction terms. The results supported our hypotheses based on the dissimilarity model. Classroom norms of behavior appeared to affect the relation between involvement in bullying and peer preference, in that early adolescents who bullied were more likely to be rejected by their peers in a classroom where bullying was non-normative. In classrooms where bullying was normative, adolescents who bullied were less likely to be rejected or were even liked by their peers (i.e., positive scores on peer preference). The same was true for victimization, although victims still had low scores on peer preference even when victimization was normative. Theoretical and practical implications of these results are discussed in terms of directions for future research and intervention in bullying.
