School-Age Bullying Victimization and Perpetration: A Meta-Analysis of Prospective Studies and Research

The role of moral disengagement in youth bullying behaviour

Moral disengagement, a term coined by Bandura, explains how people can hurt others and behave immorally, contradicting their beliefs and values and yet live peaceably with themselves. He developed a conceptual model of moral disengagement based on the Social Cognitive Theory of moral agency. By activating moral disengagement mechanisms, people can disregard their moral standards and behave immorally without any self-censure. This paper synthesises the extensive research on moral disengagement in a youth bullying context to demonstrate the conceptual strength of moral disengagement theory for research and interventions on bullying. It advances the understanding of the contextual basis of moral disengagement by examining its diverse role in bullying episodes that includes bullying perpetration, bullying victimisation and bullying bystanders. The analysis of the different components of moral disengagement representing the loci of the disengagement mechanisms sheds light on how the disengagement processes function in the youth bullying context. Its role as both a moderator and mediator further advances its divergent functioning in the youth bullying context. Finally, implications of the review for advancing knowledge on the moral basis of youth bullying are discussed with suggestions for the development of interventions to attenuate the use of moral disengagement.

Longitudinal and Reciprocal Effects in the Association Between School Bullying and Homicidal Ideation During Early Adolescence

Several cross-sectional studies indicated a positive association between school bullying and homicidal ideation during early adolescence. However, few longitudinal studies investigated this association. This study examined whether a bi-directional relationship exists within the longitudinal association between bullying victimization or bullying perpetration and homicidal ideation among early adolescents using a Random Intercept Cross-Lagged Panel Model. A total of 1611 early adolescents (39.5% girls; Mage = 12.50 years, SD = 0.50) were recruited from the Chinese Early Adolescents Cohort study. Data on bullying victimization, bullying perpetration, and homicidal ideation collected during three time points (September 2019, September 2020, and September 2021) were used. Bullying victimization showed a significant positive association with homicidal ideation at the between-person level. Bullying victimization and bullying perpetration had a bi-directional relationship with homicidal ideation at the within-person level. Additionally, this study considered the impact of biological sex-based differences and bullying types on adolescents' homicidal ideation. Based on these findings, school bullying might exhibit unique reciprocal associations with homicidal ideation.

Motor self-efficacy and physical education in school bullying

In recent years, there has been a notable increase in bullying rates in school. Bullying is characterized as a repeated set of malicious actions by an individual or group toward another individual in an imbalanced power dynamic, resulting in physical, psychological, social, or material harm to the victim, with the intention of causing social exclusion. The scientific literature has investigated the factors that influence this type of behavior, environmental factors, such as school location and student age, as well as other factors, such as gender and level of physical fitness, also play an important role. This study examined the correlation between motor self-efficacy and bullying, considering that physical activity acts as a regulator in these cases. The Kolmogorov-Smirnov test was employed to assess the normality of the data distribution, and Spearman's Rho test was used to analyze the relationship between each dimension of the EBIPQ and E-AEM scores. The Cronbach's alpha was used to evaluate the reliability of each instrument. The results indicated a significant inverse correlation between the EBIP-Q and E-AEM in the variables of sex, educational stage and school environment. In conclusion, an inverse correlation was observed between motor self-efficacy and bullying, indicating that higher levels of motor self-efficacy are related to lower levels of bullying victimization. Motor self-efficacy could be used as a tool to reduce bullying situations at school. It would be important for government policies to encourage the practice of physical activity in all areas of life in order to improve motor self-efficacy and end bullying.

Bullying Victimization and Youth's Likelihood of Carrying a Handgun

Recent research suggests that bullying victimization increases the risk of handgun carrying among adolescents. Yet, little to no research has considered whether different types of bullying victimization (i.e., physical, verbal, cyber) shape handgun-carrying behaviors among youth. Understanding these relationships can, however, inform intervention efforts addressing youths' access to and motives for carrying handguns. The purposes of this study are twofold. First, we establish whether there is a relationship between bullying victimization and youth handgun carrying. Second, we seek to determine whether certain types of bullying victimization are associated more strongly with handgun carrying than others, using data from the 2022 Florida Youth Substance Abuse Survey (FYSAS, n = 47,572), a statewide representative sample of Florida middle school and high school students. The results from multinomial regression models indicate that physical bullying and cyberbullying victimization were associated with an elevated risk of carrying a handgun in the past 12 months. Interventions that underscore the importance of comprehensive anti-bullying interventions that not only address traditional physical aggression among adolescents but also mitigate the evolving challenges posed by unsupervised digital spaces may reduce the risk of handgun carrying.

Psychological maltreatment by teachers and peer victimization in Chinese youth: Depression and aggression as mediators

BACKGROUND

Psychological maltreatment by teachers and peer victimization are significant public health issues among youth. However, few studies have verified transactional associations between psychological maltreatment by teachers and peer victimization at the within-person level and the mediating roles of depression and aggression have yet to be fully evaluated.

OBJECTIVE

This study examined the transactional associations between psychological maltreatment by teachers and peer victimization from middle childhood to early adolescence, separating within- and between-person variation. The study also examined whether youth's depression and aggression mediated the associations.

PARTICIPANTS AND SETTING

A total of 4945 Chinese youth (Mage = 9.92 years, SD = 0.73 53 % boys) completed a packet of measures on five occasions at 6-month intervals from May of 2017 to May of 2019.

METHODS

Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were used to distinguish between- and within-person effects.

RESULTS

The results indicated that: (a) Psychological maltreatment by teachers predicted peer victimization, and vice versa; (b) Depression (but not aggression) mediated the associations from peer victimization to psychological maltreatment by teachers.

CONCLUSIONS

The findings supported bidirectional spillover effects between adverse teacher-student and peer interactions and demonstrated at the within-person level that such effects were transmitted indirectly via youth's depression.

Perceived Social Support and Health Care Spending as Moderators in the Association of Traditional Bullying Perpetration with Traditional Bullying and Cyberbullying Victimisation among Adolescents in 27 European Countries: A Multilevel Cross-National Study

Existing research has documented the association between bullying perpetration and bullying victimisation. However, it is still unclear how different sources of social support moderate the association between bullying perpetration and bullying victimisation at a cross-national level. Using multilevel binary logistic regression models, this study examined the moderating role of public health care spending and perceived social support (i.e., family and teacher support) in the association between traditional bullying perpetration and victimisation by traditional bullying and cyberbullying among adolescents across 27 European countries. Country-level data were combined with 2017/18 Health Behaviour in School-aged Children (HBSC) survey data from 162,792 adolescents (11-, 13-, and 15-year-olds) in 27 European countries. Results showed that adolescents who perpetrated traditional bullying had a higher likelihood of being victimised by traditional bullying and cyberbullying than adolescents who did not bully others. Results also indicated that the magnitude of the positive association between traditional bullying perpetration and victimisation by traditional bullying and cyberbullying was mitigated among adolescents with more family, teacher, and public health care support. These findings support the notion that multilayered systems of social support could play a vital role in bullying prevention and intervention strategies to address bullying among adolescents.

Do testosterone and cortisol levels moderate aggressive responses to peer victimization in adolescents?

Aggressive reactions to peer victimization may be tempered by hormone levels. Grounded on the dualhormone hypothesis (DHH), which proposes that testosterone (T) is associated with aggressive behavior only when cortisol (C) is low, this study assessed whether the combination of T and C moderated adolescents' aggressive responses to peer victimization. The study involved 577 adolescents (50.4% girls, aged 12-17 years), who completed measures of online and offline victimization and perpetration of aggressive behavior in three waves over the course of one year. Moreover, they provided salivary samples to measure T and C levels. Multilevel analyses showed a three-way interaction between T, C, and victimization levels for both online and offline aggressive behaviors. In both cases, the adolescents with high T and high C or low T and low C responded with more aggressive behaviors when victimized or provoked by peers. The T/C ratio was only associated with aggressive behavior in the girls' sample. The results are opposite to those predicted by the DHH, but they are consistent with the findings of other studies that examined aggressive behaviors as reactions to provocations. These results suggest that some combinations of T and C predict higher aggressive reactions to peer victimization.

Longitudinal relations between bullying victimization and aggression: The multiple mediation effects of anger rumination and hostile automatic thoughts

Bullying victimization is widely accepted to be associated with aggression. However, the mechanisms underlying this relationship remain unknown. To examine the long-term impact of bullying victimization on aggression, the present study tested the potential mediating effects of both anger rumination and hostile automatic thoughts. A total of 809 undergraduates from four universities across China (74.80% female; Mage = 19.63 years, SD = 0.82 years) completed the survey on three occasions, with a 6-month delay between Time 1 and Time 2 and a 1-year interval between Time 2 and Time 3. A cross-lagged model of anger rumination and hostile automatic thoughts was developed to test whether they predicted one another, and two structural models were constructed to test their mediating roles in bullying victimization and aggression. Findings indicated that anger rumination and hostile automatic thoughts are mutually predictable; the correlation between bullying victimization and aggression is mediated independently by anger rumination and hostile automatic thoughts, and the chain mediation of bullying victimization predicting aggression first through anger rumination and then through hostile automatic thinking was established. In addition, an alternative mediation model is also significant, with hostile automatic thoughts as the primary mediator and anger rumination as the secondary mediator. These results highlight the significance of anger rumination and hostile automatic thoughts in the long-term effects of bullying victimization on aggression. Interventions designed to reduce undergraduate students' anger rumination and hostile automatic thoughts may help reduce their aggression.

Development of symptoms of oppositional defiant disorder from preschool to adolescence: the role of bullying victimization and emotion regulation

BACKGROUND

Childhood oppositional defiant disorder (ODD) is associated with adverse outcomes which can continue to impair life well into adulthood. Identifying modifiable etiological factors of ODD is therefore essential. Although bullying victimization and poor emotion regulation are assumed to be risk factors for the development of ODD symptoms, little research has been conducted to test this possibility.

METHODS

A sample (n = 1,042) from two birth cohorts of children in the city of Trondheim, Norway, was assessed biennially from age 4 to 14 years. Parents and children (from age 8) were assessed with clinical interviews to determine symptoms of ODD, children reported on their victimization from bullying, and teachers reported on children's emotion regulation.

RESULTS

Oppositional defiant disorder symptoms increased from age 4 to 6, from age 8 to 10, and then started to wane as children entered adolescence. A Random Intercept Cross-Lagged Panel Model revealed that increased emotion regulation predicted a reduced number of ODD symptoms across development (β = -.15 to -.13, p < .001). This prediction was equally strong for the angry/irritable and argumentative/defiant dimensions of ODD. No longitudinal links were observed between bullying victimization and ODD symptoms.

CONCLUSIONS

Improving emotion regulation skills may protect against ODD symptoms throughout childhood and adolescence.

Predicting Risk of Bullying Victimization among Primary and Secondary School Students: Based on a Machine Learning Model

School bullying among primary and secondary school students has received increasing attention, and identifying relevant factors is a crucial way to reduce the risk of bullying victimization. Machine learning methods can help researchers predict and identify individual risk behaviors. Through a machine learning approach (i.e., the gradient boosting decision tree model, GBDT), the present longitudinal study aims to systematically examine individual, family, and school environment factors that can predict the risk of bullying victimization among primary and secondary school students a year later. A total of 2767 participants (2065 secondary school students, 702 primary school students, 55.20% female students, mean age at T1 was 12.22) completed measures of 24 predictors at the first wave, including individual factors (e.g., self-control, gender, grade), family factors (family cohesion, parental control, parenting style), peer factor (peer relationship), and school factors (teacher-student relationship, learning capacity). A year later (i.e., T2), they completed the Olweus Bullying Questionnaire. The GBDT model predicted whether primary and secondary school students would be exposed to school bullying after one year by training a series of base learners and outputting the importance ranking of predictors. The GBDT model performed well. The GBDT model yielded the top 6 predictors: teacher-student relationship, peer relationship, family cohesion, negative affect, anxiety, and denying parenting style. The protective factors (i.e., teacher-student relationship, peer relationship, and family cohesion) and risk factors (i.e., negative affect, anxiety, and denying parenting style) associated with the risk of bullying victimization a year later among primary and secondary school students are identified by using a machine learning approach. The GBDT model can be used as a tool to predict the future risk of bullying victimization for children and adolescents and to help improve the effectiveness of school bullying interventions.

Time Trends in Adolescent School Absences and Associated Bullying Involvement Between 2000 and 2019: A Nationwide Study

Education is a central determinant of adolescent health. School absences and bullying involvement jeopardize wellbeing, mental health, and educational attainment. We analyzed time trends in school absenteeism over two decades and examined the association of absenteeism with bullying involvement.We analyzed data from the nationwide School Health Promotion study, with self-reported data from Finnish middle school students in grades 8 and 9 (ages 14-17, N = 1 000 970). Questionnaires assessed frequency of illness absences (IA), truancy, frequency of bullying victimization, bullying perpetration, and involvement in both bullying perpetration and victimization. Frequent school absences were defined as occurring on more than 3 days during the prior month (2000-2015), or at least weekly (2017-2019).Frequent IA increased from 12% to 2000 to 22% in 2015. In 2017-2019, frequent IA was reported by 3.5%. Frequent truancy declined from 9% to 2000 to 4% in 2015, and remained at 4% during 2017-2019. Bully victimization was reported at least weekly by 6.9%, perpetration by 5.4% and victimization-perpetration by 1.9% of participants in total. In a logistic regression model, every type of bullying involvement increased odds for both IA and truancy.Since bullying involvement was associated with both IA and truancy, particular concern should be raised for adolescents involved in bullying, and for their social and educational functioning. The concurrent increase in IA and decrease in truancy may reflect destigmatization of mental health problems or other changes in reporting absenteeism.

Factors Predictive of Being Bullies or Victims of Bullies in US Elementary Schools

We analyzed a population-representative cohort (N=13,611; Mage at kindergarten, first, and second grade = 67.5, 79.5, and 91.5 months, respectively) to identify kindergarten to second grade factors predictive of being bullies or victims during third to fifth grade. We did so by estimating a block recursive structural equation model (SEM) with three sets of predictors. These were: (a) individual and school socio-demographics; (b) family distress and harsh parenting; and (c) individual behavior and achievement. Relations between each of the included variables and the bullying outcomes were simultaneously estimated within the SEM. Thus, each variable served as a control for estimating the effects of the other variables. We used robust standard errors to account for student clustering within schools. Results indicated that externalizing problem behavior strongly predicted being a bully ([ES] = .56, p<.001) and a victim (ES=.29, p<.001). We observed a negative relation between being Hispanic and being a victim (ES = -.10, p<.001) and a positive relation between being Black and being a bully (ES = .11, p<.001). We also observed statistically significant relations between a family's socioeconomic status and being a bully (ES = -.08, p<.001) as well as school poverty and being a victim (ES = .07, p<.001). The results advance the field's limited understanding of risk and protective factors for bullying perpetration or victimization during elementary school and provide additional empirical support for assisting young children already exhibiting externalizing problem behaviors.

Applying GST to Understand and Contextualize Bullying: A Conjunctive Analysis of Case Configurations

Drawing from Agnew's general strain theory, this study examines whether certain risk factors have a consistent effect across different situational contexts that characterize bullying perpetration. A conjunctive analysis of case configurations was conducted to examine and identify situational factors that increase adolescents' risks for bullying perpetration using data from the 2019 Minnesota Student Survey. Results from a sample of 166,176 U.S. adolescents show that (1) incidents of traditional bullying perpetration cluster significantly among dominant situational profiles; (2) students most likely to be bullies experience victimization, but students least likely to bully their peers rarely experience bullying victimization; and (3) being a victim of traditional bullying can increase the chances of traditional bullying perpetration in some situational contexts, but can have almost no influence on perpetration in other contexts. Current findings are discussed considering existing bullying scholarship and recommendations for policy and future areas of research are presented.

Antecedents of sibling aggression and bullying victimization: The parallel and serial contributions of depressive symptoms and substance use

PURPOSE

Sibling aggression has received attention as a common form of family violence. However, further research is needed to elucidate several antecedents of sibling aggression perpetration and bullying victimization, such as substance use and depressive symptoms. Additionally, more studies are needed to identify the mediating paths of depressive symptoms and substance use, which could explain the association between bullying victimization and sibling aggression perpetration on the one hand and the association between sibling aggression victimization and bullying victimization on the other hand, while controlling for exposure to family violence and demographic variables. The current study tested two separate mediational models guided by the displaced aggression theory and self-medication hypothesis.

METHOD

The present study used the Bullying, Sexual, and Dating Violence Trajectories From Early to Late Adolescence in the Midwestern United States, 2007-2013 dataset. The original sample consisted of 1162 middle school students who were initially surveyed and followed into three high schools. For the current study, the first wave was used, which included a sample of 1101 adolescents. Structural equation modeling (SEM) was conducted to first examine whether bullying victimization was associated with sibling aggression perpetration. Then another model was conducted to test whether sibling aggression victimization was associated with bullying victimization.

RESULTS

In the first model, results suggest bullying victimization is positively associated with sibling aggression. Mediation results indicated depressive symptoms and substance use serially mediated the relation between bullying victimization and sibling aggression. In the second model, results suggest that sibling aggression victimization is positively associated with bullying victimization. Parallel mediation results indicated that depressive symptoms alone and not substance use individually explained the association between sibling aggression victimization and bullying victimization. Finally, serial mediation results indicated that depressive symptoms and substance use serially mediate the association between sibling aggression victimization and bullying victimization.

LIMITATIONS

Limitations include self-report measures and cross-sectional design; therefore, we could not estimate casual relationships.

CONCLUSION

The implications of these findings suggest the need for continued attention to school-based bully prevention efforts and family relations interventions. Such efforts might be associated with reductions in bullying victimization and sibling aggression.

Psycho-Social Correlates of Cyberbullying among Polish Adolescents

Cyberbullying has recently attracted attention due to its increasing prevalence and serious consequences for both victims and perpetrators. The objective of this population-based study was to examine the determinants of a person becoming a perpetrator of cyberbullying, including personal resources (emotional self-regulation, self-esteem, internal locus of control, optimism), social skills (prosocial behavior, assertiveness, cognitive empathy, cooperation), peer relationships (peer support, threats from peers, peer rejection, dislike of peers), and problematic Internet use (excessive Internet use, impulsive reactions to Internet deprivation). Participants (N = 541) were students at elementary schools (age 14-15) in Ostroleka, a city in central-eastern Poland. Two-part regression was used to explore protective/risk factors of the likelihood of an individual using cyberviolence (dichotomous part: involvement in violence) and how often it is used (continuous part: frequency of cyberbullying). The results showed that the emotional component is crucial to cyberbullying, as indicated by the importance of emotional self-control, which reduces the frequency of cyberbullying. Other important factors are assertiveness, impulsive response to limited Internet access (which increases the likelihood of engaging in cyberbullying) and fear of peers (which reduces its frequency). In turn, the importance of pro-sociality (which inhibits engagement) and peer support (which promotes engagement) points to the second important component of cyberbullying-that is, group mechanisms. At the same time, the results indicate that while the importance of Internet addiction as a risk factor for cyberbullying should not be underestimated, the amount of time spent online cannot be seen as the source of the problem. The study leads to the conclusion that effective interventions targeting cyberbullying should focus on the development of more adaptive styles of coping with emotions.

Bullying victimization and internalizing and externalizing problems in school-aged children: The mediating role of sleep disturbance and the moderating role of parental attachment

BACKGROUND

Studies have shown that bullying victimization may be related to internalizing and externalizing problems; however, the mechanism underlying this relationship remains unknown. This study explored the mediating role of sleep disturbance and the moderating role of parental attachment.

METHODS

A total of 1543 Chinese primary school students (M age = 8.92 years, SD1.7 years; range, 6-12) completed bullying victimization, sleep disturbance, and parental attachment measures, and provided information on their parents' occupations. The parents or guardians (n = 1995) also completed ratings on their children's internalizing and externalizing problems.

RESULTS

It was found that bullying victimization directly affected internalizing and externalizing problems and also influenced sleep disturbance. Regardless of the parent's socioeconomic status, parental attachment was found to moderate the relationship between bullying victimization and internalizing problems.

CONCLUSIONS

These findings contribute to understanding the partial mediating mechanism of sleep disturbance in the association between bullying victimization and internalizing and externalizing problems. The protective role of parental attachment proved central to preventing internalizing problems in bullied children. Intervention programs that enhance parental attachment and improve sleep quality could assist in mitigating the impact of bullying victimization on internalizing or externalizing problems.

Association between Bullying Victimization and Aggression in Lebanese Adolescents: The Indirect Effect of Repetitive Negative Thinking-A Path Analysis Approach and Scales Validation

(1) Background: The purpose of the present study was to validate the Perseverative Thinking Questionnaire (PTQ) and the Buss-Perry Aggression Questionnaire-Short Form (BPAQ-SF) and test whether repetitive negative thinking plays an indirect role in the relationship between bullying victimization and aggression among Lebanese adolescents. (2) Methods: This cross-sectional study was conducted between January and May 2022 and included 379 Lebanese adolescent students (64.9% females, mean age 16.07 years). (3) Results: The three-factor solution of the PTQ and the four-factor solution of the BPAQ-SF showed excellent model fit. PTQ mediated the association between bullying victimization and physical aggression, verbal aggression, hostility, and anger. (4) Conclusions: This study expands on previous research by showing that repetitive negative thinking, an impactful socio-cognitive factor for students' mental health, has a mediating (indirect) effect on the cross-sectional relationship between bullying victimization and aggression. This suggests that interventions aiming to prevent aggressive behaviors among adolescent students may be more effective if focused on repetitive negative thinking.

Adolescents' Expectations for Types of Victim Retaliation Following Direct Bullying

Little is known about adolescents' expectations around how victims of bullying might retaliate following victimization. These expectations are important as they may inform adolescent's own behaviors, particularly intervention behaviors, in regard to bullying and potential retaliation. This study investigated adolescents' retaliation expectations and expected bystander reactions to retaliation following physical and social bullying. Participants included 6th grade (N = 450, M_age = 11.73 years, SD = 0.84) and 9th grade (N = 446, M_age = 14.82 years) adolescents (50.2% female, 63.3% European American, 22.9% African American, 3.9% Latino/a, 7% Multiracial, 2.9% Other) from middle-to-low-income U.S. public schools. Participants responded to open-ended prompts about victim responses to bullying, rating retaliation acceptability, and likelihood of engaging in bystander behaviors. ANOVAs were conducted to examine differences in retaliation expectation by type of aggression. Further, linear regressions were used to explore what factors were related to participants' expectations regarding bystander intervention. Participants expected victims to retaliate by causing harm and expected the type of retaliation to match the type of bullying. Younger participants were more specific and males were more likely to expect physical harm than females. Finally, acceptability of retaliation predicted bystander interventions. Adolescents expect aggressive retaliation suggesting that intervention might focus on teaching them ways to respond when they are bullied or observe bullying.

Association of health-risk behaviors with perceived academic performance among middle and high school students: A cross-sectional study in Shanghai, China

Adolescence is a susceptible period to establish health-risk behaviors, which may have an impact on academic performance. The aim of this study was to investigate the association between health-risk behaviors (HRBs) and perceived academic performance (PAP) of adolescents in Shanghai, China. The data of the present study included three-round Shanghai Youth Health-risk Behavior Survey (SYHBS). This cross-sectional survey investigated multiple HRBs of students involved in dietary behaviors, physical activity and sedentary behaviors, intentional and unintentional injury behaviors, and substance abuse behaviors, as well as PAP by using self-reported questionnaire. Using a multistage random sampling method, 40,593 middle and high school students aged 12 to 18 years were involved. Only participants with complete data on HRBs information, academic performance and covariates were included. A total of 35,740 participants were involved in analysis. We used ordinal logistic regression to analyze the association between each HRB and PAP adjusting for sociodemographic, family environment and duration of extracurricular study. The results showed that students who did not eat breakfast or drink milk everyday were more likely to have a lower PAP, with a decreased odds of 0.89 (95%CI: 0.86-0.93, P<0.001) and 0.82 (95%CI: 0.79-0.85, P<0.001), respectively. The similar association was also found in students who did exercise ≥60 minutes for less than 5 days/week, spend time on watch TV beyond 3 hours/day and other sedentary behaviors. Most intentional and unintentional injuries, and ever smoked were associated with a lower PAP. Our finding suggests that multiple HRBs negatively associated with PAP of adolescents. It needs to raise public health concerns with HRBs in adolescents, and to develop and implement comprehensive interventions on HRBs.

Bullying and Cyberbullying Perpetration and Victimization: Prospective Within-Person Associations

Bidirectional associations between bullying and cyberbullying have consistently identified during adolescence. However, little is known about how this relationship works on the within-person level, after controlling for potential overlap at the between-person level. This study examined the bidirectional longitudinal associations between bullying and cyberbullying perpetration and victimization during 18-month period over four time points. A total of 2835 participants, aged 11 to 16 years in time 1 (50% girls; M_age = 13.13, SD = 1.06) were surveyed. Random intercept cross-lagged analyses revealed the stability of bullying perpetration and victimization. Cyberbullying victimization predicted inversely bullying and cyberbullying perpetration. The results indicate spirals of positive long-term associations between bullying (perpetration and victimization) and cyberbullying perpetration but no long-terms spirals of victimization.

The impact of gender and age on bullying role, self-harm and suicide: Evidence from a cohort study of Australian children

There has been limited longitudinal investigation to date into the association between bullying, self-harm, and suicidality in Australia and the impact of specific demographic differences on this relationship. This is despite the continued rise in the incidence of bullying, self-harm, and suicide. As such, the current study draws on data from the Longitudinal Survey of Australian children (LSAC) to examine the association between bullying, self-harm, and suicidality and explore the impact of demographic differences across three bullying related behaviors (being bullied, bullying others and being both bullied and bullying others). The evidence indicates that bully-victims exhibit the highest risk of self-harm and suicidality in Australia. When considering demographic differences, it was identified that females and adolescents aged 16-17-years-of-age had the highest risk of self-harm and suicidality. Further, a direct curvilinear relationship between age and the categories of self-harm was identified with an inflection point around 16-17 years. The study supports the need for further investigation into the association between bullying, self-harm, and suicidality longitudinally with a particular focus on other moderators.

Are Perceived Executive Functions Beneficial for Adolescents Who Experience Peer Victimization?

Peer victimization can lead to dysfunctional cognitions and numerous internalizing psychological problems. Thus, it is essential to identify factors that can moderate the impact of victimization. This study aimed to analyze the potential moderating role of perceived executive functions (PEF) in the impact of peer victimization (traditional and online) on internalizing symptoms (depression and social anxiety), early maladaptive schemas (disconnection/rejection domain), and PEF in adolescents. A two-wave longitudinal study was carried out with 680 Spanish adolescents between 12 and 17 years of age (M = 14.58, SD = 1.36; 41.18% girls). Participants completed measures of self-reported executive functions, traditional and online victimization, early maladaptive schemas of the disconnection/rejection domain, depressive symptoms, and social anxiety symptoms in waves 1 and 2. Traditional and online perpetration was completed only in wave 1. The results indicated that when PEF were high (i.e., adolescents perceive that they have good executive functions), traditional and online victimization predicted more schemas of the disconnection/rejection domain and internalizing symptoms of depression and social anxiety. In non-victims, high PEF showed a protective role in the development of depressive symptoms and schemas of the disconnection/rejection domain. The findings highlight that PEF have a protective role that disappears when victimization (traditional and online) occurs.

Which Children are Frequently Victimized in U.S. Elementary Schools? Population-based Estimates

We analyzed a population-based cohort of 11,780 U.S. kindergarten children to identify risk and protective factors predictive of frequent verbal, social, reputational, and/or physical bullying victimization during the upper elementary grades. We also stratified the analyses by biological sex. Both girls and boys displaying kindergarten externalizing problem behaviors were at consistently higher risk of frequent victimization during 3rd-5th grade (for the combined sample of boys and girls, verbal odds ratio [OR] = 1.82, social OR = 1.60, reputational OR = 1.85, physical OR = 1.67, total OR = 1.93). Hispanic children relative to non-Hispanic White children and those from higher income families were the most strongly and consistently protected from victimization. Boys were more likely to be physically bullied but less likely to be verbally, socially or reputationally bullied than girls. Other variables including disability, cognitively stimulating parenting, academic achievement, and internalizing behavior problems had statistically significant but less consistent and generally weaker relations with frequent victimization.

Risk behaviors as correlates of victimization of U.S.-born and foreign-born Asian, Black, and Latinx adolescents in the United States

The current study examines the association between risk behaviors and victimization and race-based victimization amongst U.S.-born and foreign-born Asian, Black, and Latinx adolescents. Data were derived from the U.S. subset of the 2009-2010 Health Behavior in School-aged Children study. Samples include 662 Asian, 2413 Black, and 3188 Latinx adolescents (M = 12.9, SD = 1.75, 48.6% female) in grades 5-10. Univariate analyses, t-test analyses, and multiple linear regression analyses were conducted. Aggressive behavior was associated with victimization for U.S.-born and foreign-born Asian, Black, and Latinx adolescents. Race-based aggressive behavior was correlated for U.S.-born and foreign-born Black and Latinx adolescents. Smoking was positively associated with victimization amongst foreign-born Asian adolescents. Alcohol use was correlated with victimization and race-based victimization amongst foreign-born Latinx adolescents. Marijuana use was related to victimization amongst U.S.-born Black adolescents. Physical fighting was shown to be positively correlated with race-based victimization for U.S.-born Latinx adolescents. Carrying a weapon was associated with victimization and race-based victimization for U.S.-born and foreign-born Latinx adolescents. It was also associated with victimization amongst U.S.-born Asian adolescents. Befriending deviant peers was negatively associated with U.S.-born and foreign-born Black adolescents and U.S.-born Latinx adolescents, but positively associated with U.S.-born Asian adolescents.

Bullying in Adolescents: Differences between Gender and School Year and Relationship with Academic Performance

School bullying is a phenomenon of unjustified aggression in the school environment that is widespread throughout the world and with serious consequences for both the bully and the bullied. The objectives of this research were to analyze the differences between the different bullying categories by gender and academic year in primary and secondary education students, as well as their relationship with academic performance. To categorize students according to their bullying experiences, the European Bullying Intervention Project (EBIPQ) Questionnaire was used. The Chi-square test was used to compare the scores obtained by the students in the EBIPQ based on gender and academic year, and the one-way ANOVA test was used to analyze its relationship with academic performance. Research participants were 562 students from the 5th (n = 228) and 6th (n = 186) primary school years and the 1st (n = 134) and 2nd (n = 94) secondary school years. They were males (50.5%) and females (49.5%) ranging in ages from 10 to 15 years old (mean = 11.66, standard deviation = 1.206). The results showed statistically significant differences in gender and academic year, indicating a greater number of boys in the role of the bully/victim and girls in that of non-bully/non-victim. The most aggressive students were in the 2nd year of ESO (12–13 years old). Regarding academic performance, statistically significant differences were obtained that confirm the hypothesis that performance or average grade varies according to the category of bullying in which students find themselves. The academic performance of the non-bully/non-victim and those in the victim category was found to be higher than that of bullies and bully/victim students.

Longitudinal Link Between Bullying Victimization and Bullying Perpetration: A Multilevel Moderation Analysis of Perceived School Climate

Existing theories and empirical studies have evidenced the association between bullying victimization and bullying perpetration. However, it is still unclear what factors mitigate or alter this risk linkage between bullying victimization and bullying perpetration to reduce bullying incidents. Guided by the social-ecological theory, this study used a longitudinal design to examine the moderating role of school climate in the association between bullying victimization and bullying perpetration at both the within-person and between-person levels among Chinese adolescents across a 1-year period. Participants included 2,997 Chinese adolescents (M_age = 14.9, 49.7% male) from 5 secondary schools. Results suggested that students who experienced high levels of bullying victimization were also involved in high levels of bullying perpetration over time (i.e., the positive within-person effect of bullying victimization on bullying perpetration). Results also showed that the between-person level of perceived school climate interacted with the within-person level of bullying victimization to predict the within-person level of bullying perpetration (i.e., cross-level effects). More specifically, the magnitude of the positive association between bullying victimization and bullying perpetration at the within-person level was mitigated among students with higher perceptions of school climate at the between-person level. Findings of the study highlighted the causal effect of bullying victimization on bullying perpetration and the buffering role of perceived school climate in the longitudinal association between bullying victimization and perpetration, which was consistent with the risk-buffering model but not the healthy context paradox hypothesis. Furthermore, the findings provided implications for bullying prevention and intervention services by using multitiered systems of support in bullying prevention efforts and highlights the need for promoting positive school climate.

Peer Victimization, Peer Aggression and Depressive Symptoms over Time: A Longitudinal Study with Latent Growth Curves

Most empirical research on the relationship between peer victimization, aggression, and mental health has been conducted with correlational designs. Much of this research has also focused primarily on linking peer victimization with either the potential aggressive behaviors of victims or a deterioration in their mental health. This study analyzes the relationship between peer victimization, peer aggression, and depressive symptoms in adolescents over time. The participants are 194 adolescents (49.2% boys, 50.8% girls) aged between 10 and 13 years (M = 10.88, SD = 0.84). The results of the growth modeling analysis indicate that the trajectories are interconnected: as victimization decreases, adolescent aggression and depressive symptoms also decrease. In addition, it is observed that victimization decreased in the same way in boys and girls, while aggression and depressive symptoms showed a smaller reduction in girls. Finally, the results and their potential practical implications are discussed.

Integrative Brain Dynamics in Childhood Bullying Victimization: Cognitive and Emotional Convergence Associated With Stress Psychopathology

Bullying victimization is a form of psychological stress that is associated with poor outcomes in the areas of mental health and learning. Although the emotional maladjustment and memory impairment following interpersonal stress are well documented, the mechanisms of complex cerebral dysfunctions have neither been outlined nor studied in depth in the context of childhood bullying victimization. As a contribution to the cross-disciplinary field of developmental psychology and neuroscience, we review the neuropathophysiology of early life stress, as well as general psychological stress to synthesize the data and clarify the versatile dynamics within neuronal networks linked to bullying victimization. The stress-induced neuropsychological cascade and associated cerebral networks with a focus on cognitive and emotional convergence are described. The main findings are that stress-evoked neuroendocrine reactivity relates to neuromodulation and limbic dysregulation that hinder emotion processing and executive functioning such as semantic cognition, cognitive flexibility, and learning. Developmental aspects and interacting neural mechanisms linked to distressed cognitive and emotional processing are pinpointed and potential theory-of-mind nuances in targets of bullying are presented. The results show that childhood stress psychopathology is associated with a complex interplay where the major role belongs to, but is not limited to, the amygdala, fusiform gyrus, insula, striatum, and prefrontal cortex. This interplay contributes to the sensitivity toward facial expressions, poor cognitive reasoning, and distress that affect behavioral modulation and emotion regulation. We integrate the data on major brain dynamics in stress neuroactivity that can be associated with childhood psychopathology to help inform future studies that are focused on the treatment and prevention of psychiatric disorders and learning problems in bullied children and adolescents.

The Online Hate Speech Cycle of Violence: Moderating Effects of Moral Disengagement and Empathy in the Victim-to-Perpetrator Relationship

Adolescents around the globe are increasingly exposed to online hate speech (OHS). And yet little is known about the varying roles of involvement and the determinants of adolescents' hate speech perpetration. Building on previous research, this study aims to test the cycle of violence hypothesis for OHS and to analyze whether moral disengagement (MD) and empathy moderate the victim-to-perpetrator relationship. The sample consists of 3,560 seventh to ninth graders (52.1 percent girls), recruited from 40 schools across Germany and Switzerland. Self-report questionnaires were administered to assess OHS involvement, MD, and empathy. Multilevel analyses revealed that victims of OHS were more likely to report OHS perpetration. In addition, victims of OHS were more likely to report OHS perpetration when they reported higher levels of MD than those with lower levels of MD. Finally, victims of OHS were less likely to report OHS perpetration when they reported higher levels of empathy than those with lower levels of empathy. The findings extend the cycle of violence hypothesis to OHS and highlight the need to address MD and empathy in hate speech prevention. Implications for future research will be discussed.

Sibling, Peer, and Cyber Bullying Among Children and Adolescents: Co-occurrence and Implications for Their Adjustment

Bullying across the sibling, peer, and cyber context has consistently been associated with a range of long-term health and well-being consequences for children and adolescents. Although research examining different bullying forms simultaneously in the same study are emerging, it remains unclear to what extend sibling, peer, and cyber bullying co-occur and in what ways they are associated. Moreover, previous work has demonstrated that children and adolescents who experience multiple forms of victimization are at a particular risk of adverse outcomes. However, whether different constellations of co-occurring bullying forms have differential impacts has not yet been investigated sufficiently. The aim of the present study was to examine the frequencies of isolated and co-occurring sibling, peer, and cyber bullying as well as to explore their independent and cumulative relationships with child adjustment. This study was based on a sample of 329 children and adolescents aged between 9 and 15. Bullying experiences across the sibling, peer, and cyber context in the previous 6 months were assessed via self-report. Youth further reported on emotional problems, conduct problems, sleep problems, and academic achievement via an online questionnaire. Sibling, peer, and cyber bullying were uniquely associated with child outcomes. A cumulative relationship between bullying victimization across contexts and emotional problems, conduct problems, and sleep problems could be identified, while bullying perpetration across contexts was only linked to more conduct problems in a cumulative manner. The findings have important practical implications arguing for the adoption of a holistic approach toward bullying in prevention and intervention.

Linking Emotional Intelligence, Physical Activity and Aggression among Undergraduates

Several indicators are strongly related to health and well-being in university students, such as emotional intelligence and physical activity. At the same time, some qualities threaten it and are incompatible with students’ adaptation to society in general, such as aggressive behaviours. The aim of this research is to analyse the relationship established between emotional intelligence using TMMS-24, physical activity, using IPAQ, and aggression behaviours in university students. For this purpose, a descriptive, cross-sectional and non-experimental study was developed with 932 undergraduates (M = 20.55; SD = 3.673). The findings highlight how emotional intelligence and physical activity practice decrease violent behaviour in university students. In addition, men tend to have more aggressive behaviours than women as well as the relation between physical activity and emotional intelligence is stronger in all its dimensions. Results highlight the importance of including emotional intelligence programs in order to enable undergraduate well-being.

Perceived Parental Warmth, Peer Perpetration, and Peer Victimization: Unraveling Within-Child Associations from Between-Child Differences

Although perceived parental warmth and "peer victimization and peer perpetration" are believed to be unidirectionally related, researchers have not examined the possibility of bidirectional relations among them, especially with regard to within-child relations. We thus explored the dynamic longitudinal associations among children's perceived parental warmth (maternal warmth and paternal warmth), peer perpetration, and peer victimization at the within-child level. A total of 3720 Chinese children (M_age = 9.95 years at Time 1, 46.1% girls) were investigated on five occasions, every 6 months. Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were applied to estimate the within-child associations among these variables. The results were: (1) for peer perpetration, peer perpetration inversely predicted subsequent perceived parental warmth, while perceived maternal (but not paternal) warmth inversely predicted subsequent peer perpetration; (2) for peer victimization, perceived maternal and paternal warmth both inversely predicted a child's subsequent peer victimization, and perceived parental warmth and peer victimization bidirectionally predicted each other; and (3) peer perpetration and peer victimization bidirectionally predicted each other. These findings enhance understanding of how perceived parental warmth temporally interrelates with peer perpetration and peer victimization from a positive spillover theory perspective, as well as how peer perpetration temporally interrelates with peer victimization from a negative vicious cycle perspective.

Pathways From Witnessing Parental Intimate Partner Violence to Involvement in Bullying: Empirically Testing a Proposed Conceptual Framework

We tested a proposed conceptual framework in which we hypothesized that witnessing parental intimate partner violence (witnessing parental IPV) is linked to children's bullying and peer victimization. We also hypothesized that the relationship between witnessing parental IPV and bullying and peer victimization in childhood would be mediated by increased psychological problem behavior, school absences, and problematic peer interactions. We utilized data from the National Survey of Children's Health. We found that witnessing parental IPV was positively related to children's bullying and peer victimization not only directly, but also indirectly through the mediating role of psychological problem behavior, school absences, and problematic peer interactions. Our findings highlight the importance of exploring the mechanisms by which bullying and peer victimization increase in those who have witnessed parental IPV.

Why Do Immigrant and Swedish Adolescents Engage in Ethnic Victimization? Common and Distinct Underlying Factors

Youth of immigrant background are at risk of experiencing victimization due to their ethnic or cultural background. However, limited knowledge is available regarding why youth victimize their immigrant peers, and whether the factors associated with engagement in ethnic victimization vary across adolescents of different background. To address this gap in knowledge, the present study aimed to elucidate the common or differential factors associated with engagement in ethnic victimization among immigrant and native youth. The analytical sample included seventh grade students residing in Sweden from 55 classrooms (N = 963, M_age = 13.11, SD = 0.41; 46% girls; 38% youth of immigrant background). The results showed that being morally disengaged and engaging in general victimization are the common denominators of engagement in ethnic victimization for immigrant and Swedish youth. Low levels of positive attitudes toward immigrants provide a foundation for ethnic victimization among Swedish youth, but not youth of immigrant background. Classroom ethnic composition was not significantly related to engagement in ethnic victimization in either group. Predictors of engagement in ethnic victimization seem to have similarities and differences among immigrant and Swedish youth. The factors involved require further attention in developing strategies to combat bias-based hostile behaviors in diverse school settings.

Bullying, Cyberbullying and the Overlap: What Does Age Have to Do with It?

School bullying and cyberbullying represent the most common forms of victimization during childhood and adolescence in many countries across the globe. Although they can be studied as distinct phenomena with their own defining characteristics, there is evidence to suggest that they are related and often co-occur. The present research aimed to estimate the rates of school bullying and cyberbullying, studied their evolution by age, and analyzed any possible overlap between the two. An empirical study was carried out with a large sample of children and adolescents in Galicia, Spain (N = 2083), where 10–17 year olds were presented with The European Bullying Intervention Project Questionnaire and European Cyberbullying Intervention Project Questionnaire. School bullying was found to be more prevalent than cyberbullying, with 25.1% involved as victims and 14.3% as bully-victims, while the cyberbullying rates were 9.4% for victims and 5.8% for bully-victims. Perpetration rates were similar for school and cyberbullying (4.4% and 4.3% respectively). The overlap between both phenomena adds to the evidence for a whole-community approach to tackling all types of bullying and victimization experiences, as opposed to each in silo. The clear age differences in bullying behaviours also suggest the appropriateness of tailoring anti-bullying programs to target specific age groups.

The Influence of Personality Traits on School Bullying: A Moderated Mediation Model

We recruited 1,631 middle and high school students to explore the relationship between personality traits and school bullying, and the moderated and mediating roles of self-concept and loneliness on this relationship. Results showed that (1) neuroticism had a significant positive predictive effect on being bullied, extroversion had a significant negative predictive effect on being bullied, and agreeableness had a significant negative predictive effect on bullying/being bullied; (2) loneliness played a mediating role between neuroticism and bullied behaviors, extroversion and bullying behaviors, and agreeableness and bullying/bullied behaviors; (3) self-concept played a moderating role on the mediation pathway of loneliness on neuroticism, extraversion, agreeableness and bullying behaviors. Therefore, to reduce the frequency of school bullying among adolescents, we should not only reduce their levels of loneliness but also improve their levels of self-concept.

Rumination as a Mediator of the Prospective Association Between Victimization and Bullying

Although there is evidence of concurrent associations between victimization and bully perpetration, it is still unclear how this relation unfolds over time. This study investigates whether victimization in childhood is a prospective risk factor for bully perpetration in early adolescence, and examines rumination as a socio-cognitive factor that may mediate this association. Participants included 553 third graders (43.2% boys; M_age = 9.85), with follow-up assessments when they were in fourth, seventh, and eighth grade. Results indicated that more frequent victimization in grades 3 and 4 was indirectly associated with bully perpetration in grade 8, through rumination in grade 7 about past victimization experiences in elementary school. This pattern remained regardless of whether the rumination elicited feelings of anger or sadness. Our findings demonstrate one pathway through which frequent victimization can lead to perpetration and underscore the important role of rumination in victims’ subsequent adjustment. Implications for future interventions are discussed.

Sex-Based Differences in Criminal Victimization of Adolescents: A Meta-Analysis

While general criminological theories, including low self-control, social bonds, routine activities, and risky lifestyles are increasingly used to explain criminal victimization, there is some evidence these theories may omit important sex differences. To date, the empirical evidence remains mixed, which may be an artifact of methodological differences. This study used three-level meta-analytic methods to assess the use of various predictors derived from criminological theory on a variety of criminal victimization types, sample characteristics, and differences in research design. In a total sample of 166,650 females and 129,988 males in 115 studies using 95 unique datasets of adolescents (average age = 10-19), the meta-analysis revealed that elements of risky lifestyles are largely sex-neutral, while some sex-specific effects of bonds, routine activities, and prior victimization are observed. Implications for criminological theory, developmental and life course research on adolescent victimization, and avenues for prevention are discussed.
