Why Does a Universal Anti-Bullying Program Not Help All Children? Explaining Persistent Victimization During an Intervention

Here Comes Revenge: Peer Victimization Relates to Neural and Behavioral Responses to Social Exclusion

The aim of this study was to examine whether repeated victimization relates to differential processing of social exclusion experiences. It was hypothesized that experiences of repeated victimization would modulate neural processing of social exclusion in the insula, anterior cingulate cortex, and lateral prefrontal cortex. Furthermore, we hypothesized that repeated victimization relates positively to intentions to punish excluders. Exploratively, associations between neural processing and intentions to punish others were examined. The sample consisted of children with known victimization in the past two years (n = 82 (behavioral) / n = 73 (fMRI), 49.4% girls, Mage = 10.6). The participants played Cyberball, an online ball-tossing game, which was manipulated so that in the first block participants were equally included and in the second block they were excluded from play. Victimization was not related to neural activation during social exclusion, although there were indications that victimization may be related to increased insula activation during explicit exclusion. Behaviorally, repeated victimization was related to more intention to punish excluders. Neural activation during social exclusion did not predict intentions to punish excluders, but results tentatively suggested that increased insula activation during social exclusion may be related to increased intentions to punish. Together, these results provide a replication of earlier Cyberball studies and point toward differential processing of social exclusion by children who are victimized.

Parental Risk and Protective Factors Associated with Bullying Victimization in Children and Adolescents: A Systematic Review and Meta-analysis

The main objective of this meta-analysis was to investigate how modifiable parental factors are related to traditional and cyberbullying victimization in children and adolescents. A systematic literature search of modifiable parental factors associated with bullying victimization was conducted using PubMed, PsycINFO, Scopus, and Web of Science electronic databases. Meta-analyses were performed to assess the mean effect sizes of the associations between the broader categories of parental factors (risk and protective) and bullying victimization (traditional and cyber), as well as between specific parental factors and bullying victimization (traditional and cyber). The differential impact of maternal and paternal factors (risk and protective) was examined. Age and gender were tested as moderators. Out of the 13,171 records identified, 158 studies met the inclusion criteria. Larger evidence was found for the association between parental risk (i.e., authoritarian parenting, aversiveness, inter-parental conflict, over-involvement, permissive parenting, and withdrawal) and protective (i.e., authoritative parenting, autonomy granting, warmth, and monitoring) factors, respectively, and traditional bullying victimization, with parental warmth, aversiveness, and withdrawal being the only common related predictors for traditional and cyberbullying victimization. The effect sizes were generally small. Maternal and paternal factors showed similar patterns of association with both types of bullying victimization. Age had a moderating effect on the association between parental protective factors and cyberbullying victimization. Overall, the present findings suggest that parental factors are relevant in protecting or putting children at risk for bullying victimization, especially in the offline context.

The Resilience Factor: Examining its Potential to Alleviate Shame and Guilt in School Bullying

School violence, in particular bullying by peers, has become a problem on the public agenda. In the context of bullying, children exposed report high levels of shame and guilt which increase victimization since involves a humiliating experience associated with the lack of acceptance by the peer group and can negatively affect mental health. Both emotions have been previously studied in peer violence context. Now we aim to examine resilience as a potential factor to alleviate shame and guilt in school bullying. We conducted a study to test if resilience mediates the feeling of shame and guilt effect of being exposed to bullying; that is, if resilience entails protective behaviors that favour the dissipation of the risk of feeling shame and guilt when exposed to direct violence in school. First, we adapted to Mexican Spanish the research instrument Short Version of the State Shame and Guilt Scale (SSGS-8, Cavalera et al., 2017)-; then we conducted a quantitative, explanatory, cross-sectional approach study; both were carried out in two different non-urban high schools near the city of Monterrey, Mexico, randomizing groups. We found through a moderated mediation analysis that resilience is a key piece to transform shame and practically alleviate negative school violence consequences the indirect effect of resilience on the relationship between direct violence in school and shame was moderated by gender, better for boys than for girls. As its presence restrain shame in those who have been exposed to direct violence in school, it is important to strengthen resilience in adolescents. Promoting the development of shame resilience in adolescents is crucial to prevent them from questioning whether something is wrong with them when exposed to violence. We must continue making efforts to eradicate violence in schools through prevention programs and public policies.

Do classroom relationships moderate the association between peer defending in school bullying and social-emotional adjustment?

Peer defending has been shown to protect bullied peers from further victimization and social-emotional problems. However, research examining defending behavior has demonstrated positive and negative social-emotional adjustment effects for defending students themselves. To explain these mixed findings, researchers have suggested that associations between defending behavior and social-emotional adjustment may be buffered by protective factors (i.e., defender protection hypothesis) or exacerbated by vulnerability or risk factors (i.e., defender vulnerability hypothesis). Consistent with these hypotheses, the present study aimed to investigate whether relationships with teachers and peers would moderate the association between defending behavior and social-emotional adjustment. This three-wave longitudinal study examined the association between peer nominated defending behavior and later self-reported depressive symptoms and self-esteem in 848 Belgian students in Grades 4-6 (53% girls; Mage = 10.61 years, SD = 0.90 at Wave 1). Peer nominated positive and negative teacher-student relationships (i.e., closeness and conflict) and peer relationships (i.e., acceptance and rejection) were included as moderators. Clustered multiple linear regression analyses demonstrated that defending behavior did not predict later depressive symptoms (β = -0.04, p = .80) or self-esteem (β = -0.19, p = .42). The lack of these associations could be explained by the defender protection and vulnerability hypotheses. However, contrary to our expectations, teacher-student closeness and peer acceptance did not play a protective role in the association between defending behavior and social-emotional adjustment (β = -1.48-1.46, p = .24-0.96). In addition, teacher-student conflict and peer rejection did not put defending students at risk for social-emotional maladjustment (β = -1.96-1.57, p = .54-0.97). Thus, relationships with teachers and peers did not moderate the association between defending behavior and later depressive symptoms and self-esteem.

Are there negative cycles of peer victimization and rejection sensitivity? Testing ri-CLPMs in two longitudinal samples of young adolescents

This study's aim was to examine whether there are negative increasing cycles of peer victimization and rejection sensitivity over time. Drawing from Social Information Processing Theory, we hypothesized that victimization leads to higher levels of rejection sensitivity, which would put adolescents at risk for higher future victimization. Data were collected in a four-wave study with 233 Dutch adolescents starting secondary education (Mage = 12.7 years), and a three-wave study with 711 Australian adolescents in the last years of primary school (Mage = 10.8 years). Random-intercept cross-lagged panel models were used to disentangle between-person from within-person effects. In each sample, a significant between-person association was found: adolescents with higher levels of victimization as compared to their peers also reported higher levels of rejection sensitivity. At the within-person level, all concurrent associations between individual fluctuations of victimization and rejection sensitivity were significant, but there were no significant cross-lagged effects (except in some sensitivity analyses). These findings demonstrate that victimization and rejection sensitivity are interrelated, but there may not be negative victimization-rejection sensitivity cycles during the early-middle adolescent years. Possibly, cycles establish earlier in life or results are due to shared underlying factors. Further research is needed examining different time lags between assessments, age groups, and contexts.

Is there really a healthy context paradox for victims of bullying? A longitudinal test of bidirectional within-and between-person associations between victimization and psychological problems

The finding that victims' psychological problems tend to be exacerbated in lower-victimization classrooms has been referred to as the "healthy context paradox." The current study has put the healthy context paradox to a strict test by examining whether classroom-level victimization moderates bidirectional within- and between-person associations between victimization and psychological adjustment. Across one school year, 3,470 Finnish 4th to 9th graders (Mage = 13.16, 46.1% boys) reported their victimization, depressive symptoms, anxiety, and self-esteem. Three types of multilevel models (cross-lagged panel, latent change score, and random-intercept cross-lagged panel) were estimated for each indicator of psychological adjustment. Findings indicated that the healthy context paradox emerges because classroom-level victimization moderates the prospective effect of victimization on psychological problems, rather than the effect of psychological problems on victimization. In classrooms with lower victimization, victims not only experience worse psychological maladjustment over time compared to others (between-person changes), but also higher maladjustment than before (absolute within-person changes).

What Works for Whom in School-Based Anti-bullying Interventions? An Individual Participant Data Meta-analysis

The prevalence of bullying worldwide is high (UNESCO, 2018). Over the past decades, many anti-bullying interventions have been developed to remediate this problem. However, we lack insight into for whom these interventions work and what individual intervention components drive the total intervention effects. We conducted a large-scale individual participant data (IPD) meta-analysis using data from 39,793 children and adolescents aged five to 20 years (Mage = 12.58, SD = 2.34) who had participated in quasi-experimental or randomized controlled trials of school-based anti-bullying interventions (i.e., 10 studies testing nine interventions). Multilevel logistic regression analyses showed that anti-bullying interventions significantly reduced self-reported victimization (d =  - 0.14) and bullying perpetration (d =  - 0.07). Anti-bullying interventions more strongly reduced bullying perpetration in younger participants (i.e., under age 12) and victimization for youth who were more heavily victimized before the intervention. We did not find evidence to show that the inclusion of specific intervention components was related to higher overall intervention effects, except for an iatrogenic effect of non-punitive disciplinary methods-which was strongest for girls. Exploratory analyses suggested that school assemblies and playground supervision may have harmful effects for some, increasing bullying perpetration in youth who already bullied frequently at baseline. In conclusion, school-based anti-bullying interventions are generally effective and work especially well for younger children and youth who are most heavily victimized. Further tailoring of interventions may be necessary to more effectively meet the needs and strengths of specific subgroups of children and adolescents.

Association between negative parent-related family interactions and child social anxiety: A cross-cultural systematic review and meta-analysis

This meta-analysis systematically evaluates the strength and direction of the association between negative parent-related family interactions and child social anxiety, and identifies several influencing moderators. Two investigators independently searched international (PsycINFO, PubMed, and Web of Science) and Chinese (CNKI, WanFang, and VIP) databases from their inception dates until March 5, 2023, for suitable articles. Of the 5771 identified records, 85 studies were selected based on inclusion of at least one of the following three dimensions of negative family interactions: insecure attachment (n = 27), parent-related family conflicts (n = 19), or negative parenting styles (n = 46). Meta-analyses showed that all three dimensions were significantly associated with child social anxiety (insecure attachment: r = 0.271, p < 0.0001; parent-related family conflicts: r = 0.226, p < 0.0001; negative parenting styles: r = 0.186, p < 0.0001). For all three dimensions, this association was stronger in children from East Asian culture than in those from European or American culture. In addition, age group, information source, and publication year also significantly moderated this association. Our findings will help guide further research and provide recommendations for the development of effective interventions for reducing social anxiety.

The effectiveness of the Dutch Meaningful Roles program in children: a study protocol for a cluster randomized controlled study

BACKGROUND

A positive, prosocial classroom climate is associated with improved social competence and academic achievement, as well as with decreased internalizing problems and antisocial behavior in children. It is expected that motivation to behave prosocially is needed to achieve a prosocial climate in the classroom, and that such motivation can be enhanced through three components of self-determination theory (SDT): competence, relatedness, and autonomy. The goal of this protocol is to describe the design of a study aiming to evaluate the effectiveness of a classroom-based program based on SDT components promoting a prosocial classroom climate.

METHODS

A cluster randomized controlled trial (RCT) will be conducted to examine the effectiveness of the classroom-based program Meaningful Roles, aiming to improve prosocial classroom climate through increasing children's intrinsic prosocial motivation, stimulated by increasing social autonomy, social competence, and social relatedness. A multi-informant (i.e., children, teachers, and school leaders) and multi-method (i.e., questionnaires and focus groups) approach will be used to assess primary outcomes (i.e., prosocial behavior, intrinsic (prosocial) motivation, social autonomy, social competence, and social relatedness) and secondary outcomes (i.e., school wellbeing, social position, bullying, victimization, and civic skills), as well as moderators (i.e., working elements, child, teacher, school, and program characteristics, and program integrity).

DISCUSSION

The current study will provide information on the effectiveness of a classroom-based program promoting a prosocial classroom climate. It is of crucial importance that the school environment can provide a positive, prosocial classroom climate in which children feel safe and can achieve optimal social and academic competence and wellbeing.

Joint Developmental Trajectories of Likability and Popularity: Associations with Social Behavior among Chinese Adolescents

The beginning of secondary school is a critical time point of adolescents' development as they entered a new peer context in which social status was re-established. As the key indicators of social status, likability and popularity co-occur but also display distinct developmental trajectories over time. Nevertheless, little is known about the joint developmental trajectories of likability and popularity among adolescents and how identified trajectories are associated with important social behavior. The current study examined the joint developmental trajectories of likability and popularity among Chinese adolescents and their associations with social behavior (prosocial behavior, aggression, and peer victimization) over time. A total of 1509 Chinese 7th grade students (53.6% male, M_age = 13.1, SD = 0.67) participated in self-report and peer nomination assessments on three occasions at 6-month intervals. Parallel process latent growth mixture models revealed four distinct trajectories of likability and popularity: social status decreasing, average, high social status, and social status increasing. The high social status group showed the highest levels of prosocial behavior, the lowest levels of peer victimization, and higher aggression than the average group. The social status decreasing group and social status increasing group exhibited the lower prosocial behavior as well as the higher aggression and peer victimization compared to the average group over time. The findings highlight the co-occurrence but diversity of developmental patterns of likability and popularity in adolescence.

The relation between harsh parenting and bullying involvement and the moderating role of child inhibitory control: A population-based study

Harsh parenting has been linked to children's bullying involvement in three distinct roles: perpetrators, targets (of bullying), and perpetrator‐targets. To understand how the same parenting behavior is associated with three different types of bulling involvement, we examined the moderating roles of children's inhibitory control and sex. In addition, we differentiated between mothers’ and fathers’ harsh parenting. We analyzed multi‐informant questionnaire data from 2131 families participating in the Dutch Generation R birth cohort study. When children were three years old, parents reported on their own harsh parenting practices. When children were four, mothers reported on their children's inhibitory control. At child age six, teachers reported on children's bullying involvement. Our results revealed that fathers’, and not mothers’, harsh parenting increased the odds of being a perpetrator. No moderation effects with children's inhibitory control and sex were found for the likelihood of being a perpetrator. Moderation effects were present for the likelihood of being a target and a perpetrator‐target, albeit only with mothers’ harsh parenting. Specifically, for boys with lower‐level inhibitory control problems, mothers’ harsh parenting increased the odds of being a target. In contrast, for boys with higher‐level inhibitory control problems, mothers’ harsh parenting decreased the odds of being a target. Furthermore, for girls with higher‐level inhibitory control problems, mothers’ harsh parenting increased the odds of being a perpetrator‐target. Overall, our results underscore the importance of differentiating by children's cognitive skills and by parent and child sex to fully understand how harsh parenting and bullying involvement are related.

Empirical and theoretical foundations of family interventions to reduce the incidence and mental health impacts of school bullying victimization

Bullying victimisation is a serious risk factor for mental health problems in children and adolescents. School bullying prevention programs have consistently produced small to moderate reductions in victimisation and perpetration. However, these programs do not necessarily help all students affected by bullying. Paradoxically whole-school programs lead to higher levels of depression and poorer self-esteem for students who continue to be victimised after program implementation. This may be because some elements of whole-school programs make victims more visible to their peers, thus further eroding their peer social status. Three main identified risk factors for children and adolescents who continue to be victimised following school bullying prevention programs are peer rejection, internalising problems, and lower quality parent-child relationships. All are potentially modifiable through family interventions. A large body of research demonstrates the influence of families on children's social skills, peer relationships and emotional regulation. This paper describes the theoretical foundations and empirical evidence for reducing the incidence and mental health outcomes of school bullying victimisation through family interventions. Family interventions should be available to complement school efforts to reduce bullying and improve the mental health of young people.

The Healthy Context Paradox: When Reducing Bullying comes at a Cost to Certain Victims

Bullying remains one of the most serious problems affecting school systems around the world. The negative consequences of bullying in the short and long term have been widely documented, showing that victimized students are at greater risk of suffering psychosocial distress. In this paper, we first summarize the current situation of bullying prevention, adopting a contextual perspective, and briefly highlighting the characteristics of the most effective prevention programs. Secondly, we address a disturbing phenomenon detected in classrooms where bullying has been reduced through interventions and which has been termed “the healthy context paradox”. In these healthier contexts, students who remain in a situation of victimization have been found to present poorer psychological adjustment after the intervention. Understanding the causes of this phenomenon may offer clues for the prevention of bullying. In this regard, we present three hypotheses recently proposed to explain the phenomenon. Finally, we offer some implications for the study and prevention of bullying derived from “the healthy context paradox”.

A Meta-Analysis on Effects of Parenting Programs on Bullying Prevention

Bullying is a serious public health concern across the globe. While there are a number of bullying interventions with parental components, limited efforts have been made to synthesize the impacts of parenting programs on bullying prevention. This meta-analysis aimed to review and examine parenting programs on bullying reduction that involving both school-based and home visiting anti-bullying programs. The overall effect size supported a significant outcome on bullying reduction (d = .640, 95% confidence interval [CI] [0.239, 1.041]). Results of this meta-analysis reported that participants in the parenting programs scored significantly lower on both bullying and victimization. Data from the randomized controlled trials and the pre- and posttest design studies showed evidence of highly significant effects of parenting interventions on bullying reduction. Child- and parent-related factors including parenting style, children's empathy, and parent-child interaction about bullying were found to be significantly related to the effectiveness of intervention programs. This study provides evidence to enhance policy and practice for effectively enabling parent involvement in bullying behavior reduction and to increase parent-children communication about bullying as well as parenting skills. Future researchers and practitioners may explore more about the impact of school-family partnerships and their reliance on each other to help reduce bullying.

Trajectory Classes of Relational and Physical Bullying Victimization: Links with Peer and Teacher-Student Relationships and Social-Emotional Outcomes

Bullying victimization is a prevalent problem in upper elementary school that predicts various detrimental outcomes. Increasing evidence suggests that interindividual differences in the severity of these outcomes result from differences in victimization experiences. However, longitudinal research largely overlooked victimization forms. Additionally, it is unclear how the quality of students' relationships with peers and teachers functions as a risk or protective factor for different patterns of victimization development. This one-year longitudinal study investigated joint trajectories of relational and physical victimization and examined differences between these trajectory classes regarding classroom social relationships as possible antecedents and social-emotional well-being as a possible outcome. A sample of 930 fourth to sixth graders (55 classes, 53.1% girls, M_age = 10.55, SD = 0.90) completed self-reports about relational and physical victimization and social-emotional outcomes (i.e., depressive symptoms, self-esteem). Peer nominations were used to measure the social antecedents (i.e., peer rejection and acceptance, teacher-student closeness and conflict). A 3-step approach including Latent Class Growth Analyses and Growth Mixture Modeling yielded two trajectory classes. Most students experienced low, decreasing relational and physical victimization. A smaller group experienced higher, generally stable victimization, more relational than physical. Younger students and girls were more likely to be members of the latter class. This class was more rejected, less accepted, reported more depressive symptoms and lower self-esteem. Teacher-student closeness and conflict were similar across classes. The current study showed that relational and physical victimization followed a largely parallel development. Low social status was found to be a risk factor for belonging to a victimization trajectory that is characterized by stable levels of both relational and physical victimization, with higher levels of the relational form.

Crossing ethnic boundaries? A social network investigation of defending relationships in schools

Prosocial peer relationships, such as defending against victimization, are beneficial for integration. Using the concept of multiple categorization, this study considers the extent to which similarity in gender, being in the same classroom, and similarity in network position regarding bullying or victimization contributes to the formation of cross-ethnic defending relationships among children. Longitudinal social network models were applied to complete school-level networks of 1,325 children in eight multi-ethnic elementary schools. Although same-ethnic peers were more likely to defend each other than cross-ethnic peers, similarity in gender, being in the same classroom, and similarity in network position in bullying fostered cross-ethnic defending. Moreover, being in the same classroom increased the likelihood of cross-ethnic defending even more than it did same-ethnic defending. A better understanding of how multiple categorization contributes to positive relationships between peers of different ethnic backgrounds may help to promote interethnic integration in multi-ethnic classrooms.

A Large-Scale Replication of the Effectiveness of the KiVa Antibullying Program: a Randomized Controlled Trial in the Netherlands

This study evaluates the effectiveness of the KiVa antibullying program in the Netherlands through a randomized controlled trial of students in grades 3-4 (Dutch grades 5-6). The sample involved 98 schools who volunteered to participate in the research, with 245 classes and 4383 students at the baseline (49% girls; M age = 8.7 years), who participated in five measurement waves, collected in three consecutive school years. After the baseline, two-thirds of the schools were assigned to the intervention condition (KiVa or KiVa+, the latter included an additional intervention component of network feedback to teachers) and one-third to the control condition (waiting list, care as usual) with a stratified randomization procedure. The effects of the intervention on self-reported victimization and bullying were tested using cross-classified ordered multinomial models and binomial logistic regression models. These longitudinal models showed that self-reported victimization and bullying reduced more strongly in KiVa-schools compared with control schools, with stronger effects after two school years than after one school year of implementation. The results showed that for students in control schools, the odds of being a victim were 1.29-1.63 higher, and the odds of being a bully were 1.19-1.66 higher than for KiVa students. No significant differences between KiVa and KiVa+ emerged. Overall, the findings provide evidence of the effectiveness of the KiVa program in the Netherlands.

Bullying and Victimization Trajectories in the First Years of Secondary Education: Implications for Status and Affection

Bullying is known to be associated with social status, but it remains unclear how bullying involvement over time relates to social position (status and affection), especially in the first years at a new school. The aim of this study was to investigate whether (the development of) bullying and victimization was related to the attainment of status (perceived popularity) and affection (friendships, acceptance, rejection) in the first years of secondary education (six waves). Using longitudinal data spanning the first- and second year of secondary education of 824 adolescents (51.5% girls; M_age T1 = 12.54, SD = 0.45) in the SNARE-study, joint bullying and victimization trajectories were estimated using parallel Latent Class Growth Analysis (LCGA). The four trajectories (decreasing bully, stable high bully, decreasing victim, uninvolved) were related to adolescents’ social position using multigroup analysis that examined differences in slope and intercepts (T1 and T6) of social positions, and indicated that the relative social position of the different joint trajectories was determined at the start of secondary education and did not change over time, with one exception: adolescents continuing bullying were besides being popular also increasingly rejected over time. Although bullying is functional behavior that serves to optimize adolescents’ social position, anti-bullying interventions may account for the increasing lack of affection that may hinder bullies’ long-term social development.

Effects of Implementing Multiple Components in a School-Wide Antibullying Program: A Randomized Controlled Trial in Elementary Schools

This study investigates the effectiveness of the PRIMA antibullying program for elementary education using a cluster-randomized trial with two experimental conditions (with and without student lessons) and a control group. Students of 31 schools participated in the study (N = 3,135; M_age  = 10 years). Multilevel regression analyses demonstrated positive effects of the program on peer-reported victimization and reinforcing behavior. Implementing multiple program components was related to stronger program effects. The results provide partial experimental evidence for the beneficial effects of combining student lessons and teacher training in antibullying programs. Future experimental research is needed to investigate other approaches that reduce not only peer-reported victimization, but also self-perceived bullying and victimization.

Assessment of School Anti-Bullying Interventions: A Meta-analysis of Randomized Clinical Trials

IMPORTANCE

Bullying is a prevalent and modifiable risk factor for mental health disorders. Although previous studies have supported the effectiveness of anti-bullying programs; their population impact and the association of specific moderators with outcomes are still unclear.

OBJECTIVE

To assess the effectiveness of school anti-bullying interventions, their population impact, and the association between moderator variables and outcomes.

DATA SOURCES

A search of Ovid MEDLINE, ERIC, and PsycInfo databases was conducted using 3 sets of search terms to identify randomized clinical trials (RCTs) assessing anti-bullying interventions published from database inception through February 2020. A manual search of reference lists of articles included in previous systematic reviews and meta-analyses was also performed.

STUDY SELECTION

The initial literature search yielded 34 798 studies. Included in the study were articles that (1) assessed bullying at school; (2) assessed the effectiveness of an anti-bullying program; (3) had an RCT design; (4) reported results; and (5) were published in English. Of 16 707 studies identified, 371 met the criteria for review of full-text articles; 77 RCTs were identified that reported data allowing calculation of effect sizes (ESs). Of these, 69 independent trials were included in the final meta-analysis database.

DATA EXTRACTION AND SYNTHESIS

Random-effects and meta-regression models were used to derive Cohen d values with pooled 95% CIs as estimates of ES and to test associations between moderator variables and ES estimates. Population impact number (PIN), defined as the number of children in the total population for whom 1 event may be prevented by an intervention, was used as an estimate of the population impact of universal interventions targeting all students, regardless of individual risk.

MAIN OUTCOMES AND MEASURES

The main outcomes are the effectiveness (measured by ES) and the population impact (measured by the PIN) of anti-bullying interventions on the following 8 variable categories: overall bullying, bullying perpetration, bullying exposure, cyberbullying, attitudes that discourage bullying, attitudes that encourage bullying, mental health problems (eg, anxiety and depression), and school climate as well as the assessment of potential assocations between trial or intervention characteristics and outcomes.

RESULTS

This study included 77 samples from 69 RCTs (111 659 participants [56 511 in the intervention group and 55 148 in the control group]). The weighted mean (range) age of participants in the intervention group was 11.1 (4-17) years and 10.8 (4-17) years in the control group. The weighted mean (range) proportion of female participants in the intervention group was 49.9% (0%-100%) and 50.5% (0%-100%) in the control group. Anti-bullying interventions were efficacious in reducing bullying (ES, -0.150; 95% CI, -0.191 to -0.109) and improving mental health problems (ES, -0.205; 95% CI, -0.277 to -0.133) at study end point, with PINs for universal interventions that target the total student population of 147 (95% CI, 113-213) and 107 (95% CI, 73-173), respectively. Duration of intervention was not statistically significantly associated with intervention effectiveness (mean [range] duration of interventions, 29.4 [1 to 144] weeks). The effectiveness of anti-bullying programs did not diminish over time during follow-up (mean [range] follow-up, 30.9 [2-104] weeks).

CONCLUSIONS AND RELEVANCE

Despite the small ESs and some regional differences in effectiveness, the population impact of school anti-bullying interventions appeared to be substantial. Better designed trials that assess optimal intervention timing and duration are warranted.

Continuity and Overlap of Roles in Victims and Aggressors of Bullying and Cyberbullying in Adolescence: A Systematic Review

The objective of this study was to conduct a systematic review of research focused on analyzing the overlap and continuity of the roles in victims and aggressors of bullying and cyberbullying, as well as the exchange of roles in both harassment dynamics in adolescents. Searches in the main electronic databases for studies published in the last 20 years identified 19 studies that fulfilled inclusion criteria. The findings of the studies analyzed were not homogeneous, however, the main conclusion of all of them, to a greater or lesser extent, was that there is a component of continuity or superposition in the roles of both forms of bullying. Some studies also found an exchange of roles, especially in the case of victims and cybervictims who decide to reprimand their aggressors in an online context, becoming in cyberaggressors too. It is necessary to continue investigating the coexistence of bullying and cyberbullying and its exchange in certain contexts and people, as well as whether they are part of the same phenomenon with a certain continuity, or if cyberbullying is another expression of traditional bullying. Future intervention programs focusing on traditional school bullying could also evaluate their impact in situations of cyberbullying among peers.

Navigating the Healthy Context Paradox: Identifying Classroom Characteristics that Improve the Psychological Adjustment of Bullying Victims

The healthy context paradox—an unexpected pattern in which victims’ psychological adjustment worsens as the overall level of victimization in a classroom or school declines—implies that reducing the frequency of bullying or victimization incidents does not do enough to help victims of bullying. In light of this finding, it is imperative to identify protective factors that alleviate victimization-related distress in the peer ecology. The current study examines classroom-level peer victimization and peer-defending behaviors as moderators of the association between individual-level victimization and psychological adjustment. These classroom-level moderators were tested with a sample of 1373 adolescents (40% girls, M_age: 14 years) from 54 classrooms in South Korean middle schools. Consistent with past findings documenting the healthy context paradox, the results of multilevel modeling indicated that victimized youth experienced a lower level of depressive symptoms in classrooms where victimization was more common. Most importantly, bullied students reported fewer depressive symptoms, on average, in classrooms with relatively high levels of bully-oriented (i.e., confronting the bully), rather than victim-oriented (i.e., comforting the victim), defending behavior. These findings provide a more nuanced understanding of the role of peers’ defending behaviors toward bullied adolescents and have significant implications for anti-bullying interventions.

The P.E.A.C.E. Pack Program in Italian High Schools: An Intervention for Victims of Bullying

Background: Bullying is a serious public issue, which mainly occurs in school with negative consequences for the students involved as victims. Very few teacher-delivered interventions have shown positive changes in the victims. The present study aimed at implementing the P.E.A.C.E. (Preparation, Education. Action, Coping, Evaluation) pack program, developed in Australia, in Italian high schools. Method: The effectiveness of the program was analyzed through an observational study (pre/post-intervention), involving 551 Italian high school students who completed a questionnaire on bullying victimization, self-efficacy, and bystander behavior. The students were divided into three groups (not involved students, occasional and severe victims) according to their self-reported victimization in the pre-intervention. Results: After the intervention, severe victims (victimized once/week or more often) showed a significant decrease in victimization and higher scores in self-efficacy, while an increase in victimization was observed in the not involved students. As reported by all the groups after the intervention, classmates were perceived more likely to intervene when a bullying episode occurred. By contrast, occasional and severe victims perceived their teachers as less likely to intervene. Conclusions: The P.E.A.C.E. pack is a promising program confirming in Italian schools the effectiveness already shown in other countries. This program is very useful for severe victims, supporting their self-confidence with a decrease in the frequency of aggressive episodes.

Psychometric properties of the Japanese version of the Body Appreciation Scale-2 for Children (BAS-2C)

Despite the heightened interest in positive body image research in recent years, few studies have explored positive body image among children. Examining the Body Appreciation Scale-2 for Children (BAS-2C) using a different cultural sample than the original version would thus be beneficial in extending the research on this topic. This research aimed to validate the BAS-2C for use in Japan. The measures were administered to 243 children, and the participants completed the survey in their classrooms with the support of a teacher. The survey was repeated after four weeks. Confirmatory factor analysis showed that the one-factor structure was the same as that of the original version, and the BAS-2C was invariant across gender. Scores on the BAS-2C demonstrated good internal consistency and test-retest reliability over a four-week period. In addition, construct validity was accrued through the BAS-2C's correlation with body dissatisfaction (among girls), self-esteem, and life satisfaction. Results indicated that the BAS-2C shows good psychometric properties among Japanese children, and supports further research into positive body image in this group.

Heritability of Bullying and Victimization in Children and Adolescents: Moderation by the KiVa Antibullying Program

Objective: Bullying affects approximately a quarter of schoolchildren and is associated with numerous adverse outcomes. Although distinct risk factors for bullying and victimization have been identified, few studies have investigated the genetic and environmental underpinnings of bullying and victimization. The aims of this study were twofold: first, to examine the contributions of genetic and environmental factors to bullying and victimization, and second, to analyze whether the KiVa antibullying program moderated the magnitude of these contributions by comparing estimates derived from the KiVa versus control groups.Method: The sample comprised students from schools that participated in the evaluation of the KiVa antibullying program in Finland during 2007-2009. Bullying and victimization were measured using peer nominations by classmates. The sample for the twin analyses comprised of 447 twins (107 monozygotic and 340 dizygotic twins) aged 7-15.Results: Genetic contributions accounted for 62% and 77% of the variance in bullying and in victimization at pre-intervention, respectively. There was a post-intervention difference in the overall role of genetic and environmental contributions between the intervention and the control group for bullying and victimization, with non-shared environmental effects playing a lesser role (and genes a larger role) in the intervention than in the control group context.Conclusions: This study replicates previous findings on the genetic underpinnings of both bullying and victimization, and indicates that a school-based antibullying program reduces the role of non-shared environmental factors in bullying and victimization. The results indicate that prevention and intervention efforts need to target both environmental and (heritable) individual level factors to maximize effectiveness.

Peer victimization in single-grade and multigrade classrooms

Although peer victimization mainly takes place within classrooms, little is known about the impact of the classroom context. To this end, we examined whether single-grade and multigrade classrooms (referring to classrooms with one and two grades in the same room) differ in victim-bully relationships in a sample of elementary school children (646 students; age 8-12 years; 50% boys). The occurrence of victim-bully relationships was similar in single-grade and multigrade classrooms formed for administrative reasons, but lower in multigrade classrooms formed for pedagogical reasons. Social network analyses did not provide evidence that peer victimization depended on age differences between children in any of the three classroom contexts. Moreover, in administrative multigrade classrooms, cross-grade victim-bully relationships were less likely than same-grade victim-bully relationships. The findings did not indicate that children in administrative multigrade classrooms are better or worse off in terms of victim-bully relationships than are children in single-grade classrooms.

Bullying as a Group Process in Childhood: A Longitudinal Social Network Analysis

This study investigates the dynamic interplay between bullying relationships and friendships in a sample of 481 students in 19 elementary school classrooms (age 8-12 years; 50% boys). Based on a relational framework, it is to be expected that friendships would be formed when two children bullied the same person and that children would start to bully the victims of their friends. Similarly, it is to be expected that friendships would be formed when two children were victimized by the same bully and that children would become victimized by the bullies of their friends. Longitudinal bivariate social network analysis supported the first two hypotheses but not the latter two. This study provides evidence for group processes in bullying networks in childhood.

Correcting for norm misperception of anti-bullying attitudes

Research has documented the presence of norm misperception in the context of school bullying, as children and adolescents typically underestimate the degree to which their peers disapprove of bullying behavior. Despite commonly held attitudes in opposition to bullies and in support of helping victims, widespread misperception of the norm makes students vulnerable to acting in a manner that reinforces bullying, as they aim to align themselves with perceived peer beliefs. This study investigated whether personalized normative feedback, a social norms intervention that juxtaposes individuals’ own perceptions of peer norms against their peers’ true normative values, could operate as a mechanism by which to reduce norm misperception of peer attitudes toward bullying. Whereas this type of intervention has shown promising effects in a variety of contexts, no study to date has examined its utility in the specific context of bullying. Baseline participants included 188 seventh grade students, 175 of whom were randomized into four study groups for follow-up data collection. Individuals in the experimental condition received personalized normative feedback on attitudes toward bullying. Control conditions were the following: general normative feedback on anti-bullying attitudes, the absence of normative feedback, and personalized normative feedback on a construct separate from bullying (i.e., antidrug use attitudes). Findings indicated that personalized normative feedback on bullying attitudes led to significant change in perceived peer attitudes in the direction of the group norm, with an effect size in the small-to-medium range. No intervention effects emerged on personal attitude change. Implications highlight strategies for improving the strength of similar interventions in future research as well as the positive clinical outcomes that could result from reduced norm misperception and increased engagement in prosocial bystander behavior.

When and How Do Emotional Intelligence and Flourishing Protect against Suicide Risk in Adolescent Bullying Victims?

This study contributes to current knowledge on the protective role of emotional intelligence and flourishing in cases of suicide risk (namely depressive symptoms and suicidal ideation) in a sample of adolescent victims of traditional bullying. The proposed model tested the mediator role of flourishing in the relationship between emotional intelligence (EI) and suicide risk together with the moderating effect of EI in the relationship between low flourishing and increased suicide risk. Considering an initial sample of 1847 adolescents (52.5% female), a subsample of 494 pure bullying victims (61.3% female) took part in this research. The main results showed EI to be linked to decreased suicide risk through levels of flourishing. Moreover, EI buffered the relationship between low flourishing and the associated suicide risk. Victimized adolescents with both low levels of EI and of flourishing reported higher levels of suicide risk than their counterparts with high EI levels. This suggests the protective role of EI of both predicting higher flourishing and reducing the likelihood of suicide risk among victimized adolescents with low levels of flourishing. Finally, the practical implications of these novel findings regarding the role of EI and flourishing in the prevention of suicide risk among victimized adolescents are discussed.

Changes in delinquency according to socioeconomic status among Finnish adolescents from 2000 to 2015

Background: Scientific literature suggests that the prevalence of delinquency amongst adolescents has decreased internationally in past decades. However, whether this change is consistent across all socioeconomic groups has not yet been studied. Objective: The aim of this study was to examine changes in delinquency amongst Finnish adolescents according to socioeconomic status between 2000 and 2015. Method: A population-based school survey was conducted biennially amongst 14-16-year-old Finns between 2000 and 2015 (n = 761,278). Distributions for delinquency and socioeconomic adversities (low parental education, not living with both parents and parental unemployment in the past year) were calculated using crosstabs. Associations between delinquency, time, and socioeconomic adversities were studied using binomial logistic regression results shown by odds ratios with 95 % confidence intervals. Results: Delinquency was positively associated with all three socioeconomic adversities studied and cumulative socioeconomic adversity. Although the prevalence of delinquency varied only slightly between 2000 and 2015 in the overall population, it increased significantly amongst adolescents with most socioeconomic adversities. Conclusions: The findings indicate that socioeconomic differences in delinquency have increased amongst Finnish adolescents in past decades. Delinquency prevention and intervention programs should take socioeconomic adversities into account.

What Antibullying Program Designs Motivate Student Intervention in Grades 5 to 8?

Educators detect and intervene in a small proportion of bullying incidents. Although students are present when many bullying episodes occur, they are often reluctant to intervene. This study explored attributes of antibullying (AB) programs influencing the decision to intervene. Grade 5, 6, 7, and 8 students (N = 2,033) completed a discrete choice experiment examining the influence of 11 AB program attributes on the decision to intervene. Multilevel analysis revealed 6 latent classes. The Intensive Programming class (28.7%) thought students would intervene in schools with daily AB activities, 8 playground supervisors, mandatory reporting, and suspensions for perpetrators. A Minimal Programming class (10.3%), in contrast, thought monthly AB activities, 4 playground supervisors, discretionary reporting, and consequences limited to talking with teachers would motivate intervention. Membership in this class was linked to Grade 8, higher dispositional reactance, more reactance behavior, and more involvement as perpetrators. The remaining 4 classes were influenced by different combinations of these attributes. Students were more likely to intervene when isolated peers were included, other students intervened, and teachers responded quickly. Latent class analysis points to trade-offs in program design. Intensive programs that encourage intervention by students with little involvement as perpetrators may discourage intervention by those with greater involvement as perpetrators, high dispositional reactance, or more reactant behavior.

Working with parents to counteract bullying: A randomized controlled trial of an intervention to improve parent-school cooperation

This study examined the effectiveness of an intervention aimed at improving parent-school cooperation in counteracting bullying. Using a randomized controlled trial, data of teachers, parents of non-victimized children, and children themselves were collected at 13 intervention and 14 control schools (grades 3-6, N at post-assessment: teachers = 83, parents = 153, children = 2,510) at two time points (time lag about 6 months). Results showed positive effects of the intervention for some aspects of the primary outcomes: parents' and teachers' attitudes and efforts, whereas no effects were found of teachers' or parents' competences in counteracting bullying. No intervention effects were found for secondary outcomes: children's self-reported bullying, victimization, well-being, and self-esteem. The findings indicate that, due to the intervention, teachers and parents were more aligned and able to cooperate, even within the short time of the intervention: one school year. This is the first essential step to systematically addressing parents' role in tackling bullying; future research is needed to examine the long-term effects of parent and school interventions in enhancing the effectiveness of anti-bullying programs.

Traditional Bullying, Cyberbullying and Mental Health in Early Adolescents: Forgiveness as a Protective Factor of Peer Victimisation

Traditional and online bullying are prevalent throughout adolescence. Given their negative consequences, it is necessary to seek protective factors to reduce or even prevent their detrimental effects in the mental health of adolescents before they become chronic. Previous studies have demonstrated the protective role of forgiveness in mental health after several transgressions. This study assessed whether forgiveness moderated the effects of bullying victimisation and cybervictimisation on mental health in a sample of 1044 early adolescents (527 females; M = 13.09 years; SD = 0.77). Participants completed a questionnaire battery that measures both forms of bullying victimisation, suicidal thoughts and behaviours, satisfaction with life, and forgiveness. Consistent with a growing body of research, results reveal that forgiveness is a protective factor against the detrimental effects of both forms of bullying. Among more victimised and cybervictimised adolescents, those with high levels of forgiveness were found to report significantly higher levels of satisfaction compared to those with low levels of forgiveness. Likewise, those reporting traditional victimisation and higher levels of forgiveness levels showed lower levels of suicidal risk. Our findings contribute to an emerging relationship between forgiveness after bullying and indicators of mental health, providing new areas for research and intervention.
