Background: Suicidal ideation among college students and adolescents represents a significant public health issue worldwide. Research has indicated that emotional difficulties may mediate the relationship between bullying victimization and suicidal ideation. However, insights from Thomas Joiner's interpersonal theory and Klonsky's The Three-Step Theory suggest that suicidal ideation arises not merely from emotional distress but from the interplay of hopelessness along with these emotional challenges. Therefore, this study aims to investigate whether variouse affective problems mediated the relationship between bullying victimization and suicidal ideation among college students., Methods: In this study, we utilized a convenience sampling method to collect data from 2717 college students (mean age = 19.81 years, 22.49% male) in South China. We examined the relationships between variables using Spearman's correlation analysis. To analyze potential mediation effects, we employed PROCESS model 4 within SPSS., Results: Our findings revealed that different forms of bullying victimization can predict experiences of depression, anxiety, and social anxiety. However, these emotional responses did not significantly influenced suicidal ideation among college students. Additionally, while different forms of bullying victimization did not directly correlate with feelings of hopelessness, hopelessness was closely associated with the prevalence of suicidal ideation. Furthermore, our results highlighted a significant mediating role of psychiatric prodromal experiences in the relationship between different forms of bullying victimization and suicidal ideation., Conclusions: The results suggested that affective problems may not serve as a significant mediating factor in the relationship between bullying victimization and suicidal ideation. We proposed an integrated emotion-response model that enhances understanding of suicidal ideation among college and offers a framework for more effective prevention strategies., Competing Interests: Declarations.

General early-life bullying victimization has been used as an early-life marker of eating and body image disturbances and poor psychosocial well-being later in life. We expand existing research in this area to Chinese sexual minority (SM) men, a vulnerable and under-researched subgroup, by considering associations of general early-life bullying victimization with current eating and body image disturbances and poor psychosocial well-being. We assessed demographics, general early-life bullying victimization, past appearance teasing, current thinness- and muscularity-oriented eating and body image disturbances, and current psychosocial well-being in Chinese SM men (N = 433). Correlation and hierarchical linear regressions examined the study hypotheses. Beyond covariates (e.g., age) and past appearance teasing, general early-life bullying victimization explained significant, unique variance in all outcome variables. Specifically, higher general early-life bullying victimization was uniquely associated with more current thinness- and muscularity-oriented eating and body image disturbances and poor psychosocial well-being. Consistent with research in the Western context, findings suggest that general early-life bullying victimization is a meaningful, positive correlate of current eating and body image disturbances and poor psychosocial well-being in Chinese SM men. Future research considering sexual minority stress as a theoretical backdrop may help explain associations between general early-life bullying victimization and negative health outcomes., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 Elsevier Ltd.

Introduction: Even though existing amounts of results have shown that school bullying could be related to the main components of executive functions (EFs) (inhibitory control, working memory, and cognitive flexibility), research focused on this association yields inconsistent results., Method: To address this research gap, the current study conducted a three-level meta-analysis approach and simultaneously considered the two perspectives of the bully and victim to clarify the relationship between school bullying experienced by children and EFs. It also explored the moderating variables that affect the relationship between school bullying and EFs., Results: Based on 18 studies reporting 73 effect sizes (N = 21,725), the results revealed that the overall effect size for the association between both the bullies and victims of school bullying incidents with EFs (r bullies  = -0.154, p < .05; r victims  = -0.187, p < .001). Moderator analyses revealed that the negative correlation between bullies of school bullying and EFs was moderated by EF components, but it was not affected by gender, age, and the EF measurement method. Moreover, the negative correlation between victims of school bullying and EFs was not affected by the form of bullying, source of report, facet of EFs, EF measurement, gender, age, and culture., Conclusions: The present meta-analysis revealed a relationship between school bullying and EFs. Both bullies and victims appear to have lower EF levels. The results also emphasized that lower inhibitory control was more likely to be a crucial risk factor for bullying behavior., (© 2024 Foundation for Professionals in Services to Adolescents.)

Background: The link between school bullying and eating disorders is a complex issue that is poorly understood globally, and is further complicated by the distinct cultural nuances within China. This study aims to fill this gap by investigating the association between different types of bullying and the risk of eating disorders among college students in Shantou City, China. Additionally, this study explores the mediating role of body dissatisfaction in the relationships between bullying roles and the risk of eating disorders., Methods: The present study employed a convenience sampling technique to recruit college students aged 16 years or older from a university in Shantou. The survey encompassed socio-demographic data, as well as measures of bullying and the risk of eating disorders. Kruskal-Wallis rank sum test, logistic regression, chi-square test, and mediation analysis were used to analyze the results., Results: A total of 1643 students were investigated in this study, revealing a prevalence of the risk of eating disorders at 29.21%. Additionally, the prevalence of bullying was found to be 5.78% for bullies, 24.83% for victims, and 28.36% for bully-victims. Furthermore, all types of bullying showed a significant positive correlation with the risk of eating disorders. Notably, gender differences were observed in the associations among social manipulation, cyber victimization, cyber perpetration, and the risk of eating disorders, with males exhibiting stronger correlations. Body dissatisfaction plays a mediating role between bullying-victims and the risk of eating disorders., Conclusions: A positive association has been observed between the type of school bullying and the risk of eating disorders among college students in Shantou. Additionally, gender and body dissatisfaction have been identified as significant factors that contribute to the relationship between school bullying and the risk of eating disorders., Competing Interests: Declarations.

Introduction: Problematic gaming (PG) is a serious issue among adolescents worldwide, and there is evidence suggesting that school bullying behaviors may be associated with increased rates of PG. This study aimed to examine the associations between school bullying behaviors and PG among adolescents, with a focus on sex effects., Methods: A total of 20,197 participants were recruited from the 2023 School-based Chinese Adolescents Health Survey. Information about school bullying behaviors and PG was measured. Sampling weights were utilized to estimate the prevalence, and weighted logistic regression models were executed. Stratified analyses by sex were performed., Results: Among Chinese adolescents, the weighted prevalence of PG was 4.2%, 8.1% were identified as victims, 1.8% as bullies, and 3.4% as bully-victims. A higher frequency of school bullying behaviors corresponds to a higher prevalence of PG. After adjusting for covariates, victims (AOR = 1.34, 95% CI = 1.03-1.73), bullies (AOR = 2.08, 95% CI = 1.39-3.11), and bully-victims (AOR = 2.75, 95% CI = 2.09-3.61) were associated with PG. Moreover, the severity of PG tended to increase with the number of involved in school bullying behaviors. The interaction terms of bully-victims and sex were significant. Further stratified analyses by sex indicated that the association of school bullying behaviors with PG was stronger for females than males, especially those identified as bully-victims., Conclusion: School bullying behaviors are associated with PG among adolescents, with a stronger association found in female adolescents, particularly those identified as bully-victims. These findings suggest that implementing prevention and control measures for school bullying could help reduce PG among adolescents., Competing Interests: Declarations Ethics approval and consent to participate The study was conducted by the Declaration of Helsinki and was approved by the Sun Yat-sen University School of Public Health Institutional Review Board.

Background: Research on the associations of type-specific bullying victimization and poly-bullying victimization with suicidal ideation is limited and contradictory. This study aimed to examine these associations among school-aged adolescents., Methods: A total of 13,258 students from 3 middle schools and 4 high schools in a southern city in China completed a cross-sectional questionnaire in 2019. Multinomial logistic regressions were used to examine associations between type-specific bullying victimization and poly-victimization with suicidal ideation., Results: The latent class analysis identified three subgroups of suicidal ideation: low (70.0 %), moderate (24.0 %), and high (6.0 %). Compared with non-bullying victimization in the past year, the corresponding adjusted odds ratios [aOR] (95 % CI) of moderate and high suicidal ideation for only physical victimization were 1.74 (1.15, 2.63) and 2.51 (1.18, 5.38), respectively, for only relational victimization were 1.26 (0.97, 1.62) and 2.48 (1.65, 3.71), respectively, for only verbal victimization were 1.45 (1.17, 1.78) and 1.42 (0.90, 2.22), respectively, for only property victimization were 1.30 (1.03, 1.65) and 1.31 (0.80, 2.16), respectively, and for sexual victimization were 1.38 (1.03, 1.83) and 2.45 (1.50, 3.99), respectively. Poly-bullying victimization was associated with moderate (aOR two  = 1.45 (1.24, 1.70); aOR three  = 1.70 (1.41, 2.05), aOR four  = 2.03 (1.61, 2.58), aOR five  = 2.48 (1.74, 3.53)) and high suicidal ideation (aOR two  = 2.01 (1.49, 2.70), aOR three  = 3.87 (2.86, 5.25), aOR four  = 4.55 (3.20,6.46), aOR five  = 7.90 (5.06, 12.33))., Limitations: The research design is cross-sectional, and relevant data was based on self-reports., Conclusions: Different types of bullying victimization were associated with suicidal ideation and poly-bullying victimization and suicidal ideation association shows a dose-response-relationship., Competing Interests: Declaration of competing interest None of the authors have declared any potential conflict of interest., (Copyright © 2024 Elsevier B.V.

Background: Bullying and victimization have been studied in many contexts and classified as peer victimization in school settings and parental or sibling victimization within family settings. Yet, current research is scarce on whether victimization occurring within family settings is specific to parental or sibling victimization. Thus, the current study aims to develop a scale assessing victimization conducted by relatives and provide support for its psychometric properties., Methods: Cross-sectional and longitudinal data were collected from university students (1622 and 1045 students, respectively) and participants responded to questionnaires via an online survey., Results: EFA and CFA results demonstrated the unidimensionality of the Relative Victimization Scale (RVS) consisting of eight items. In terms of convergent validity, RVS scores were correlated with the scores on parental, sibling, and peer victimization scales and several psychological health outcomes including depression, anxiety, social anxiety, perceived stress, loneliness, negative and positive affect, life satisfaction, and resilience. Moreover, RVS explained a significant amount of variance beyond the contribution of parental, sibling, and peer victimization in those psychological health outcomes for the support of incremental validity., Conclusions: The findings of the study indicated the potential utility of the RVS in assessing the experience of relative victimization through offering support for internal consistency reliability and construct, longitudinal predictive, and incremental validity., (© 2024.

Background: Numerous studies have explored the association between social anxiety and bullying victimization. However, inconsistency are found regarding the strength and the direction of this relationship. Moreover, it remains unclear how different subtypes of bullying victimization associate with social anxiety., Objective: The purpose of this study was to conduct a meta-analysis to systematically investigate the cross-sectional and longitudinal relationships between social anxiety and bullying victimization., Participants and Setting: Individuals experiencing social anxiety and bullying victimization., Methods: The present study employed three-level random effects model to combine the correlation coefficients r to indicate the strength of the cross-sectional association between social anxiety and bullying victimization. Cross-lagged regressions were utilized to examine the prospective relationship between both variables., Results: A total of 133 cross-sectional studies reporting 220 effect sizes were included in the meta-analysis, and the results showed a significant moderate association between social anxiety and bullying victimization (r = 0.268, 95 % CI [0.244, 0.292]). Nineteen longitudinal studies were also identified, revealing that social anxiety at Time 1 significantly predicted bullying victimization at Time 2 (β = 0.067, 95 % CI [0.038, 0.096]). However, bullying victimization did not significantly predict subsequent social anxiety (β = 0.012, 95 % CI [-0.026, 0.049]). Subgroup analyses revealed that social anxiety had the strongest association with relational victimization (r = 0.382, 95 % CI [0.335, 0.430]), followed by reputational victimization (r = 0.254, 95 % CI [-0.171, 0.337]), physical victimization (r = 0.226, 95 % CI [0.144, 0.308]) and overt victimization (r = 0.202, 95 % CI [0.146, 0.257]). Social anxiety was significantly more associated with traditional bullying victimization (r = 0.281, 95 % CI [0.233, 0.328]) than cyberbullying victimization (r = 0.177, 95 % CI [0.137, 0.218]; p < 0.001)., Conclusions: Social anxiety was found to be moderately associated with and prospectively predict bullying victimization. Future research and interventions could focus on reducing social anxiety to prevent bullying victimization., (Copyright © 2024 Elsevier Ltd. All rights reserved.)

Few studies have assessed the burden of mental disorders in adolescents related to bullying victimization at the global, regional, and national levels. We analyzed adolescent mental disorder disability-adjusted life years (DALYs) attributed to bullying in 204 countries, following the Global Burden of Disease study 2019 framework. The DALYs rate of adolescent for bullying-related mental disorders global increased from 110.45 (95 % uncertainty intervals (UI): 40.76, 218.62) per 100,000 in 1990 to 138.92 (95 % UI: 54.37, 268.19) per 100,000 in 2019. The largest increase in DALYs rates were obvious in low-SDI and high-SDI regions. In 2019, the DALYs rate of adolescents with bullying-related anxiety disorders was 1.4 times higher than those depressive disorders; the DALYs rate of adolescents with bullying-related mental disorder in females was 1.3 times higher than that of male, and older adolescent (15-19 years old) was 1.4 times higher than younger adolescent (10-14 years old). High-income North America had the fastest increase in DALYs rates of mental disorders related to bullying. In general, a positive correlation was observed between bullying DALY rate of adolescent and SDIs at the regional and national levels. Our study highlights significant disparities in adolescent mental health burden from bullying. Governments must implement adaptive policies to address diverse needs effectively., Competing Interests: Declaration of competing interest None., (Copyright © 2024. Published by Elsevier B.V.)

Objectives: No comprehensive analysis has yet been published regarding global trends in childhood sexual abuse (CSA) and bullying victimization (BV). The present study offers a longitudinal perspective on their prevalence worldwide., Methods: CSA and BV rates were extracted from the Global Burden of Disease study, spanning the years 1990 to 2019 across 204 countries. Trends by gender, region, and human development index (HDI) were examined., Results: For both boys and girls, and in both high-HDI and low-HDI countries, CSA rates did not significantly change from 1990 to 2019 (p>0.05). However, BV rates increased significantly in high-HDI and low-HDI countries for both genders (p<0.001). Subsequently, we analyzed trends separately by gender across all countries, without considering development level. In this analysis, CSA rates among girls decreased from 1990 to 2000, followed by an increasing tendency after 2000; overall, an upward trend was evident between 1990 and 2019 (p=0.029). In contrast, no significant pattern was observed for boys. Notably, BV demonstrated an increasing trend across all regions when HDI was not considered (p<0.05), with African populations experiencing the most pronounced rise (p<0.001). Globally, boys consistently exhibited higher BV rates than girls., Conclusions: Our research indicates that, on a global scale, rates of CSA among girls have been rising. Additionally, BV rates have increased in all regions for both boys and girls. Notably, this trend in BV rates is occurring irrespective of HDI. These findings underscore the necessity for targeted interventions in areas with high rates of CSA and BV.

Lay Abstract: Autistic individuals face a higher risk of various forms of victimization throughout their lives, with bullying being especially prevalent during their school years. Previous studies indicate that autistic children are 2.4 times more likely to be bullied than their typically developing peers and twice as vulnerable as those with other disabilities. However, the extent of this issue among Spanish schoolchildren with autism remains unexplored. In addition, there is no information regarding the presence of bullying victimization in children with marked but undiagnosed autistic traits (i.e. subthreshold autistic traits). This study examines the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits, comparing them with peers without neurodevelopmental conditions. The study involved 323 participants (11 and 12 years old; 45 with autism or subthreshold autistic traits) from Spanish general education schools. The results revealed a higher rate of bullying victimization among autistic participants (58%; 3.1 times higher risk) and those with subthreshold autistic traits (27%; 1.5 times higher risk) compared with their peers without neurodevelopmental conditions (18.3%). Victimization was linked to more intense restrictive behaviours and increased behavioural and emotional problems. No significant associations were found with other individual or family factors. Our findings underscore the heightened risk of bullying faced by autistic pre-adolescents and those with subthreshold autistic traits at school, emphasizing the need to identify and implement preventive measures to mitigate bullying and its detrimental impact on their mental well-being and overall quality of life., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

As a global issue, peer victimization is closely associated with adolescent mental health. Although previous research has explored the relationship between peer victimization and mental health in some contexts, the school context, particularly within the Chinese cultural context, has not received sufficient attention. Based on the Healthy Context Paradox, this study aimed to explore the moderating role of school-level victimization in the relationship between individual-level peer victimization and mental health. This study tested two hypotheses by using a multilevel design: higher individual-level and school-level peer victimization are associated with higher depressive symptoms and lower life satisfaction (Hypothesis 1); school-level victimization moderates the association between individual-level peer victimization and mental health (Hypothesis 2). Participants were 39,720 adolescents (50.41% females; M age  = 13.68, SD  = 2.39) across 292 Chinese schools. They completed a set of questionnaires, including the Center for Epidemiologic Studies Depression Scale, the single-item Life Satisfaction Questionnaire, the Peer Victimization Scale, and demographics. The multilevel model indicated that both individual-level and school-level peer victimization were positively correlated with depressive symptoms and negatively correlated with life satisfaction. In schools with lower levels of victimization, there was a stronger association between individual peer victimization and adolescent mental health. A potential explanation for these results might be the victimization visibility and perceived severity in different contexts. These findings extended the discussion of the Healthy Context Paradox within the Chinese school context and provided valuable insights for developing school support strategies for victimized adolescents. School management might play a significant role in affecting the mental health of victimized adolescents., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Background: Evidence suggests a robust relationship between experiencing bullying victimization (BV) and engaging in murderous behaviors among adolescents. However, the potential mediating effect of impulsivity on the relationship between BV and murderous behaviors in early adolescents remains underexplored., Methods: A total of 5724 adolescents, with a mean age of 13.5 years, were enrolled from three middle schools in Anhui Province, China. Participants completed self-report questionnaires detailing their experiences with bullying, impulsiveness, and murderous behaviors. To assess the relationship between BV and murderous behaviors, multivariate logistic regression and Poisson regression analyses were conducted. Mediation analysis was performed using structural equation modeling., Results: After controlling for confounding factors, a positive association was found between experiencing BV and engaging in murderous behaviors (p < 0.05). Mediation analysis revealed a significant indirect effect of BV on the occurrence of murderous behaviors through impulsivity (indirect effect = 0.027, 95 % CI: 0.021, 0.033). BV appears to heighten levels of impulsivity, which in turn increases the likelihood of murderous behaviors. Additionally, sex-specific analysis indicated that impulsivity played a greater mediating role in the link between verbal and relational BV and murderous behaviors in females, while physical and cyber BV were more significant in males., Conclusions: Our findings underscore the necessity of early targeted interventions for adolescents experiencing BV and exhibiting high levels of impulsivity to mitigate their risk of engaging in murderous behaviors., Competing Interests: Declaration of competing interest All named authors declare no competing interests., (Copyright © 2024 Elsevier B.V.

Sexually and gender diverse (SGD) youth experience more peer bullying victimization than heterosexual, cisgender youth during adolescence, yet the emergence and persistence of these disparities remain underexplored. Also, it is unclear which factors are associated with these disparities across development, and how these disparities are linked to late adolescent health discrepancies. This study utilized the sample from the Millennium Cohort Study in Britain (N = 10,080; 51.3% assigned female at birth; M age  = 2.28, SD age  = 0.46 at Wave 2), in which 23.74% of youth reported non-heterosexual attraction, 21.59% reported non-heterosexual identity, and 1.08% reported gender identity not in line with the sex assigned at birth. Using latent class growth modeling, four peer bullying victimization trajectories were identified, with early peak (7.2%), late childhood peak (6.3%), adolescence onset (12.8%), and low (73.6%) rates of victimization. SGD youth, compared to heterosexual and cisgender youth, were found to have increased odds of being in the victimization-involved classes, especially the adolescence onset class. The study further revealed that SGD youth reported more mental health and relational difficulties in childhood, which were linked to their heightened risk of longer-lasting victimization. Further, long-term victimization was found to partially account for the disparities in health and well-being for SGD youth in late adolescence. In conclusion, SGD youth were more likely to experience longer-lasting bullying victimization during childhood and adolescence, its related mental and relational vulnerabilities were already established in childhood, and such victimization disparities were further linked to their detrimental health and well-being in late adolescence. The design, hypotheses, and target analyses of the current study were preregistered on 21st April 2023 at https://osf.io/f2zxy ., (© 2024. The Author(s).)

Background: Despite the implementation of antibullying policies, schools in the United Arab Emirates (UAE) witnessed an increase in bullying prevalence. The aim of our study was to assess bullying victimization in schools in the UAE, types of bullying, and factors and outcomes related to bullying behavior., Methods: A cross-sectional survey was conducted in randomly selected private and public schools in Al Ain City. A structured, self-administered questionnaire was used to collect data from students in grades 6-8 (Ages 10-15). We adapted the US CDC 'Bully Survey' for cultural relevance in the UAE through feedback from focus group meetings with teachers. Data analysis, conducted using R software, involved stratified analysis by school type and utilized Chi-Squared and Fisher's exact tests to identify factors associated with school bullying., Results: The study sample consisted of 723 students of whom 68% were males, and 58% were Emirati nationals. The overall prevalence of bullying victimization in schools was 37%, with 40% in private schools and 35% in public schools. Cyberbullying was more prevalent in private schools (37%). Physical bullying was reported by 20% and verbal bullying by 12%, with a higher prevalence of physical bullying in private schools (24%) and among males (23%). The study's findings showed significant emotional and academic impacts of bullying, including feelings of sadness and learning difficulties, contributing to a rise in school absenteeism., Conclusions: The study reveals widespread bullying victimization in UAE schools, mainly in classrooms, with group exclusion and verbal abuse as key forms. It underscores bullying's psychological impact and the greater awareness of parents compared to teachers. The effective intervention strategies should not only involve students, teachers, and school staff, but also actively engage parents by fostering stronger communication channels between schools and families, and providing parents with resources and training to recognize and address bullying. These strategies should aim to create a cohesive network involving the entire school community, thus fostering a safer and more inclusive environment for students. The findings stress the need for inclusive antibullying programs involving the entire school community to foster a safer environment., (© 2024. The Author(s).)

Background: Previous studies have shown the positive effects of bullying cognition on school bullying behavior among young people, but the mechanism underlying this association remains unclear., Methods: We conducted a cross-sectional study with 5,903 primary school students in grades 3-5 in Luzhou city. Hayes' PROCESS macro was used to test the mediating effect of psychological resilience and the moderating effect of sex on the relationship between bullying cognition and school bullying after controlling for grade., Results: Psychological resilience partially mediated the relationship between school bullying cognition and victimization ( β  = -0.0174, 95% CI: -0.0219 to -0.0132) and between perpetration ( β  = -0.0079, 95% CI: -0.0104 to -0.0055). This study revealed that sex moderated the relationship between school bullying cognition and perpetration ( β  = 0.0383, p  < 0.001) and victimization behavior ( β  = 0.0400, p  < 0.001)., Conclusion: These findings suggest that it is crucial for education regulators, schools, and families to cultivate students' school bullying cognitions and psychological resilience, which may help to decrease the prevalence of school bullying. Especially for boys, improving their bullying cognition may largely decrease its perpetration., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Fei, Li, Li, Liao, Li, Chen and Zhang.)

Social media has become a pervasive presence in everyday life, including among youths. In 2023, for the first time, CDC's nationally representative Youth Risk Behavior Survey included an item assessing U.S. high school students' frequency of social media use. Data from this survey were used to estimate the prevalence of frequent social media use (i.e., used social media at least several times a day) among high school students and associations between frequent social media use and experiences with bullying victimization, persistent feelings of sadness or hopelessness, and suicide risk. All prevalence estimates and measures of association used Taylor series linearization. Prevalence ratios were calculated using logistic regression with predicted marginals. Overall, 77.0% of students reported frequent social media use, with observed differences by sex, sexual identity, and racial and ethnic identity. Frequent social media use was associated with a higher prevalence of bullying victimization at school and electronically, persistent feelings of sadness or hopelessness, and some suicide risk among students (considering attempting suicide and having made a suicide plan), both overall and in stratified models. This analysis characterizes the potential harms of frequent social media use for adolescent health among a nationally representative sample of U.S. high school students. Findings might support multisectoral efforts to create safer digital environments for youths, including decision-making about social media policies, practices, and protections., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Aim: To investigate the association between presence of caries in anterior teeth and bullying victimization in schoolchildren., Methods: A cross-sectional study was conducted in Brazil with a sample of 387 schoolchildren aged 6 to 10 years. The presence of moderate/extensive dental caries was assessed using the International System for the Evaluation and Detection of Dental Caries (ICDAS-II). The children answered the "Olweus Bullying" (QBO). Descriptive analyses were performed, and the associations between bullying victimization and independent variables collected were determined by univariate and multivariate Poisson regression., Results: The prevalence of bullying victimization was 66.4%. Bullying victimization was higher among children who had moderate/extensive caries in some anterior teeth (p = 0.010). 8-year-old (p = 0.048), 9-year-old (p = 0.001), and 10-year-old (p = 0.002) children reported greater bullying victimization when compared to 6-year-olds., Conclusion: The presence of moderate/extensive dental caries in anterior teeth is associated with bullying victimization in schoolchildren., (© 2024.

Background: Children with developmental language disorder (DLD) experience higher levels of peer victimization than their peers. However, it is not known if such associations reflect genetic and environmental confounding. We used a co-twin control design to investigate the association of language difficulties (DLD and separately poor pragmatic language) with peer victimization and compare the developmental trajectories of peer victimization across adolescence for those with and without language difficulties., Methods: Participants were 3,400 pairs of twins in the Twins Early Development Study (TEDS), a UK-based population birth cohort. Language abilities were assessed via online tests at age 11 and peer victimization was self-reported at ages 11, 14 and 16. Language difficulties were defined as language abilities at least -1.25 SD below the mean of the TEDS sample. We performed linear regressions and latent growth curve modeling at a population level and within monozygotic and same-sex dizygotic twin pairs., Results: At population level, youth with DLD experienced higher levels of peer victimization at ages 11 (β = 0.27, 95% Confidence Interval (CI) 0.20-0.35), 14 (β = 0.15, 95% CI 0.03-0.27) and 16 (β = 0.17, 95% CI 0.03-0.32) and a sharper decline in peer victimization between ages 11 and 16 compared to their peers without DLD. The associations between DLD and peer victimization were reduced in strength and not statistically significant in within-twin models. Moreover, there was no difference in the rate of change in peer victimization between twin pairs discordant for DLD. Results were similar for the association of poor pragmatic language with peer victimization., Conclusions: Associations between language difficulties (DLD and separately, poor pragmatic language) and peer victimization were confounded by genetic and shared environmental factors. Identifying specific factors underlying these associations is important for guiding future work to reduce peer victimization among adolescents with language difficulties., (© 2024 The Authors.

Peer victimization during adolescence has a detrimental impact on the mental health of victims throughout their lives. However, it remains unclear whether these effects are gender-specific. The present study conducted a systematic review to examine the effects of peer victimization on depression status, explore potential sources of heterogeneity, and investigate gender differences in these effects. We systematically searched four electronic databases (Web of Science, PubMed, Embase, and CNKI) for relevant articles that published as far as July 2022. We then extracted odds ratios (OR) and 95% confidence intervals (CI) to assess the association between peer victimization during adolescence and depression, and potential gender differences in the relation. Meta-analysis was performed, using fixed effects models and random effects models, to evaluate the association between each exposure and the outcome. A meta-analysis of 27 studies revealed that peer victimization during adolescence was significantly associated with higher risks of depression (OR = 2.79, 95% CI [2.43, 3.21], p  < .001). This finding was consistent across subgroup analyses. In particular, the effect of peer victimization during adolescence on depression was found to be more pronounced in studies conducted in Asia (OR = 3.06, 95% CI [2.38, 3.92], p  < .001). Furthermore, five studies focused on gender differences demonstrated that peer victimization has a stronger association with the risk of depression in women (OR = 2.84, 95% CI [2.49, 3.26], p  < .001). Peer victimization during adolescence is a significant risk factor for depression, with a greater impact on women and individuals residing in Asia. Further prospective studies are needed to investigate the relationship between peer victimization and depression., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The relationships between peer bullying victimization in adolescence and substance use have been poorly studied. Thus, we examined the associations between peer bullying victimization and tobacco, alcohol and cannabis use in 496 French high school students. Peer bullying victimization was measured with a 17-item standardized assessment and analyzed as quartiles. Tobacco, alcohol, and cannabis use were assessed with the Hooked on Nicotine Checklist (HONC), the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and the Cannabis Abuse Screening Test (CAST), respectively. Total scores at the HONC (0 to 10), AUDIT-C (0 to 12), and CAST (0 to 24) were used as dependent variables in generalized linear models, adjusting for sex, age, prepared graduation, last school marks and friends outside high school. Compared to the first quartile (i.e., the least bullied students), those from the second, third and fourth quartiles had significant increase of the AUDIT-C ( B  = 0.78 [95%CI 0.17-1.40] with p  = 0.013; B  = 0.86 [95%CI 0.26;1.46] with p  = 0.005 and B  = 1.00 [95%CI 0.38;1.62] with p  = 0.002, respectively), with dose-dependent relationships ( B  = 0.33 ([95%CI 0.13; 0.52] with p  = 0.001). Those from the fourth quartile had a significant increase of the CAST ( B  = 2.13[95%CI 1.25;3.01], p  < 0.001). When examining the role of peer bullying victimization on the number of substances used, there were significant increased odds for students from the third and fourth quartiles, with dose-dependent relationships (OR = 1.24 [95% CI 1.07;1.44], p  = 0.005). These findings encourage paying a particular attention to substance use in students who report being bullied. Consequently, information and prevention using standardized screening tools should be proposed. Conversely, substance use could be an indicator of peer bullying victimization and should thus be explored.

Background: The development of bullying victimization among adolescents displays significant individual variability, with general, group-based interventions often proving insufficient for partial victims. This study aimed to conduct a machine learning-based predictive analysis of bullying victimization trajectories among Chinese early adolescents and to examine the underlying determinants., Methods: Data were collected from 1549 students who completed three assessments of bullying victimization from 2019 to 2021. Self-reported questionnaires were used to measure bullying victimization and its associated risk and protective factors. Trajectories were classified using the Group-based Trajectory Model (GBTM), while a Random Forest algorithm was employed to develop a predictive model. Associations between baseline characteristics and victimization trajectories were evaluated via multiple logistic regression analysis., Results: The GBTM identified four distinct victimization trajectories, with the predictive model demonstrating adequate accuracy across these trajectories, ranging from 0.812 to 0.990. Predictors exhibited varying influences across different trajectory subgroups. Odds ratios (ORs) were notably higher in the persistent severe victimization group compared to the low victimization group (OR for adverse school experiences: 3.698 vs. 1.386; for age: 2.160 vs. 1.252; for irritability traits: 1.867 vs. 1.270). Adolescents reporting lower school satisfaction and higher borderline personality features showed a greater likelihood of persistent severe victimization, while those with lower peer satisfaction faced increased victimization over time., Conclusions: The machine learning-based predictive model facilitates the identification of adolescents across different victimization trajectory groups, offering insights for designing targeted interventions. The identified risk factors are instrumental in guiding effective intervention strategies., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 Elsevier B.V.

This paper attempted to examine suicidal ideation among adolescents in terms of bullying victimization and emotional intelligence. It had been observed that adolescents have to face the challenge of suicidal ideation through bullying and reduce it through emotional intelligence. A sample of 1017 adolescents was sampled from public sector primary schools in the district of Gujrat, Punjab, Pakistan to conduct the cross-sectional survey. For this study, the scale of bullying victimization (Illinois Bullying Scale by Espelage & Holt, 2001), emotional intelligence (Emotional Intelligence Scale for Children & Adolescents by Batool & Hayat, 2018) and suicidal ideation (Suicidal Ideation Attribution Scale by Van Spijker, 2014) had been used to measure the responses of the students. The study findings pointed out that emotional intelligence was a significant negative predictor of suicidal ideation. Similarly, the analysis showed that bullying victimization was a significant predictor of suicidal ideation among adolescents., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: School bullying, a serious problem for the physical and mental health of adolescents, is presently a significant issue in China. It is essential to recognize and comprehend potential risk factors and establish efficient preventive strategies. The purpose of this study was to examine the association between childhood maltreatment and school bullying in adolescents and to assess the mediating role of peer relationships., Methods: Between March and April 2024, a cross-sectional survey was conducted among 2119 adolescents aged between 12 and 18 years in Guangdong Province, China. Self-report questionnaires were employed to collect data on childhood maltreatment, school bullying, and peer relationships. Subgroup analyses and mediating effects modeling were employed to analyze the data., Results: The results indicated that adolescents who had experienced maltreatment were more at risk of bullying victimization (OR: 2.92, 95% CI: 2.34-3.64, P < 0.001), bullying perpetration (OR: 2.84, 95% CI: 1.99-4.05, P < 0.001), and bully-victimization (OR: 2.93, 95% CI: 1.95-4.41, P < 0.001), compared to adolescents who have not. Sexual abuse showed the most significant connection with all forms of bullying. The mediating effect of peer relationships was found to mediate the association between child maltreatment and bullying behaviour. The results indicated that worse peer relationships may exacerbate the adverse effects of maltreatment experiences and increase the risk of adolescents becoming bullies, either perpetrators or victims of bullying., Conclusions: Child maltreatment has been identified as one of the most significant influences on bullying behaviour in adolescents. The quality of peer relationships has been demonstrated to play an important role in preventing and reducing the occurrence of bullying. The results underscore the crucial role of early intervention in cases of child maltreatment and the fostering of positive peer relationships in schools., (© 2024. The Author(s).)

Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents., Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05)., Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28-2.40), consume alcohol (OR1.43; 95%CI 1.05-1.94), have worse sleep quality (OR 1.94; 95%CI 1.28-2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08-1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22-2.27)., Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

Objective: This systematic review used established rating criteria to describe the level of evidence for interventions aimed at preventing or reducing bullying perpetration and victimization in schools, synthesized the evidence for students from racially and ethnically diverse backgrounds, and reviewed the literature for available information to conduct an economic analysis of the interventions., Methods: Major databases, gray literature, and evidence-base registries were searched to identify studies published from 2008 through 2022. The authors rated antibullying intervention models as having high, moderate, or low evidence depending on the number and rigor of studies with positive findings., Results: Overall, 80 articles reporting on 71 original research studies describing a total of 48 antibullying interventions met the inclusion criteria for this review. Two schoolwide interventions received a high-evidence rating: the KiVa ( Kiusaamista Vastaan ) Antibullying Program and the Friendly Schools program. Multilevel interventions with components at the levels of school, classroom, and individual student most consistently showed strong evidence for reducing bullying behavior in elementary and middle school grades. Four interventions yielded positive effects in reducing bullying and victimization among diverse samples of students., Conclusions: Antibullying interventions can reduce bullying in schools. Some interventions show effectiveness with students from racially and ethnically diverse backgrounds. The gains relative to per-student costs were in the range that is considered cost-effective. Most implementation costs are spent on staff training and support. Research on successful implementation of whole-school interventions and additional synthesis of evidence pertaining to program structures would further advance the antibullying evidence base., Competing Interests: The authors report no financial relationships with commercial interests.

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., (© 2024.

School bullying and depression are both serious social and public health problems among adolescents. Prior studies indicated a correlation between bullying and depression. However, the potential moderators remain largely unexplored. This study aimed to identify the mediating effect of Internet addiction and the moderating effect of living in urban or rural areas in the relationship between school bullying victimization and depression symptoms among Chinese adolescents. This cross-sectional study of adolescents was conducted using two-stage random cluster sampling of students in urban and rural public high schools in China. A moderated mediation model was constructed to uncover the underlying mechanism of school bullying victimization and depression symptoms. A total of 2,376 adolescents (52.65% females, mean age ± SD a 14.69 ± 1.76 years) were included in the study. The prevalence of clinical depression symptoms with a cut-off value of 16 on the Center for Epidemiological Studies Depression Scale (CES-D) was 21.76% (95% CI: 20.15, 23.46), and with a cut-off value of 20 on the CES-D was 13.85% (95% CI: 12.51, 15.30) for overall. Our findings indicated a significant positive association between school bullying victimization and depression symptoms (p < 0.01) and a significant mediating effect of Internet addiction in the association between school bullying victimization and depression symptoms (indirect effect = 1.143, 95% CI: 0.677, 1.609; percentage of mediation: 16.7%, 95% CI: 10.3, 23.1). This indirect relationship was partially moderated by the living in urban or rural areas in the mediation process. Specifically, the effect of school bullying victimization on Internet addiction was greater among urban adolescents (simple slope: 0.774, 95% CI: 0.524, 1.024, p < 0.01) than among rural adolescents (simple slope: 0.337, 95% CI: 0.132, 0.543, p < 0.01), but moderating effect of urban-rural areas was not significant on the relationship between Internet addiction and depression symptoms. These findings highlight the mediating role of Internet addiction and the moderating role of living areas in school bullying victimization and adolescents' depression symptoms, which provide evidence for social work, mental health services, and policy interventions for adolescents in China., (© 2024.

Left-behind children are likely to experience peer victimization, which can have detrimental consequences in their developmental outcomes. Yet, limited longitudinal research have examined peer victimization trajectories over time or the factors associated with left-behind children in China. The purpose of the present study was to examine what, if any, distinct trajectories of peer victimization exist among left-behind children and whether these trajectories are related to school climate, left-behind status, and their interactions. Participants were 853 Chinese left-behind children (M age  = 14.25, SD = 2.39; 43.4% girls) who participated in a four-wave longitudinal study conducted in rural China. Participants reported school climate (indexed by safety and order, acceptance and support, equality and fairness, autonomy and cooperation) at T1 and peer victimization across T1 to T4 spanning 2 years. Latent class growth analyses identified four peer victimization trajectories, including a stably low-decreasing group, a moderate-decreasing group, a high-decreasing group, and an increasing group. Multinomial logistic regression analyses revealed that children who perceived more positive school climate were more likely to exhibit a stably low-decreasing trajectory compared to the other three groups. In addition, among left-behind children who perceived more positive school climate, children with single-parent migrating were more likely to be members of the stably low-decreasing group as compared to those with both-parent migrating. Peer victimization among left-behind children is a concern especially for those who were left behind by both parents and perceived less positive school climate. Targeted school-based interventions and services focused on reducing peer victimization and improving school climate are needed for left-behind children, especially those with both-parent migrating., (© 2024 Society for Research on Adolescence.)

Purpose: Although the harmful outcomes of peer bullying are well-established, the effects of bullying by teachers are less understood. Teacher bullying occurs when a teacher uses their authority to punish or disparage a student beyond appropriate discipline., Methods: This study investigated the prevalence of teacher bullying and its relationship with student risk-taking behaviors in a sample of 106,865 high school students who completed a statewide school climate survey. Students were classified into four groups: no bullying (91%), only peer bullying (4%), only teacher bullying (4%), and both peer and teacher bullying (2%)., Results: Logistic regression results indicated that all victimization groups were more likely to participate in risk behaviors (substance use, weapon carrying, fighting, suicidal ideation, and attempts) than nonbullied peers, and students bullied by both peers and teachers were at greatest jeopardy of participation., Discussion: These results support greater attention to teacher bullying in antibullying efforts., (Copyright © 2024 Society for Adolescent Health and Medicine.

We identified different types of adolescent bullying perpetrators and nonbullies based on peer-reported bullying, victimization, and peer status (popularity, likeability, and rejection) and examined differences between bully subtypes in typical forms of bullying perpetrated. Moreover, we studied how bully subtypes differed from nonbullies with varying levels of victimization and peer status in academic and psychosocial adjustment. The study utilizes data from 10,689 adolescents (48.3% boys, mean age 14.7 years). Latent profile analysis identified three distinct subgroups of bullies: popular-liked bullies (13.5%), popular-rejected bully-victims (5.8%), and bully-victims (6.9%), and four groups on nonbullies. High-status bullies (popular-liked and popular-rejected) resembled nonbullies in many ways and had even lower social anxiety, whereas bully-victims were the most maladjusted group. Overall, popularity seems to protect adolescents from social anxiety, and victimization is related to internalizing problems. Results suggest that bullying, victimization, and peer status can be used to identify distinct subtypes of bullies., (© 2024 The Author(s).

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; M age  = 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., (© 2024.

Background: Bullying in school is a universal psychosocial issue that raises concerns about adolescents' safety and mental health and is positively associated with depressive symptoms. Social support could be a preventive factor that eases bullying and its psychological distress., Purpose: The primary purpose of this study was to examine the mediating effect of social support in the relationship between bullying and depressive symptoms among adolescents in Jordan. Another aim was to investigate predictors of depression based on adolescents' sociodemographic factors., Methods: In this cross-sectional, non-experimental mediational study, a stratified and systematic sampling method was used to recruit 270 Jordanian adolescents., Results: Sociodemographic variables of being female, having divorced parents, having illiterate fathers, and being older in adolescence explained 12.2% of the variance in depressive symptoms. Family social support partially mediated the relationship between bullying and depressive symptoms., Conclusion: Our findings showed that a notable proportion of adolescents experienced bullying victimization and depressive symptoms, and a positive relationship exists between these two variables. These results further highlight the role of family social support in buffering the negative impact of bullying on depressive symptoms., Implications to Practice: The study's results emphasize the significance of developing and implementing family-centered social support initiatives by nurses to lessen adolescents' bullying experiences and depressive symptomatology., Competing Interests: Declaration of competing interest No funding or conflicts of interest., (Copyright © 2024 Elsevier Inc.

Resilience is a concept of growing interest because it can systematically inform prevention measures and psychosocial interventions for children and adolescents. The aim of this study was to explore resilience factors among young people who are victims of bullying and harassment (age 9 to 16 years old). In 2021 the burden of the pandemic lockdown became an additional adversity. The study used a repeated cross-sectional design. Two datasets with a total of 2,211 participants from 2017 (N = 972) and 2021 (N = 1,239) were included. The strengths and difficulties questionnaire (SDQ) was applied to define the resilient and non-resilient groups, and the quality-of-life questionnaire (KINDL) was used to map resilience factors. A total of 227 participants reported that they were being bullied, and 604 participants reported harassments from their peers. We used correlation and regression analyses to identify which factors predicted the highest resistance to the negative effects of bullying and harassment. The results were that 77.2% of the participants stayed resilient when facing these maladjustments, but this dropped to 61.7% during the pandemic. The most important resilience factors before the pandemic were the school environment, emotional well-being, and good relations with their friends. The impact of these predictors changed during the pandemic. Emotional well-being increased in strength, school environment was reduced, and friends did not predict resilience anymore. The effect sizes were generally large to medium. As it is common to experience adversity at some stage in life, it is vital for families, schools, social and healthcare workers to be aware of the factors associated with resilience. The results of this study may contribute towards an evidence base for developing plans to increase the capacity of resilience among young people., (© 2024 The Authors.

Objectives: This study uses the bioecological model of human development and person-centered methods to describe the underlying patterns of risk and their association with bullying perpetration and victimization among U.S. children., Methods: Using the National Survey of Children's Health, this study (n = 7319) explored the underlying patterns of risks across six domains (i.e., individual, family, school, neighborhood, economic, and socio-cultural) associated with bullying perpetration and victimization among U.S. elementary school children., Results: Latent Class Analysis uncovered four patterns of risks. The low risks group (72.4%) showed the lowest rates of bullying perpetration (24.6%) and victimization (57.2%). The individual and environmental risks group (15.3%) presented moderate levels of bullying perpetration (31.8%) and victimization (67.1%). The family risks group (8.3%) showed moderate levels of bullying perpetration (35.9%) and victimization (66.0%). High risks group (4.0%) presented exceptionally high rates of bullying perpetration (59.1%) and victimization (87.3%)., Conclusion: Results suggest rates of bullying perpetration and victimization differed across the four patterns of risks. Understanding the sources of risk may be critical to alleviate bullying perpetration and victimization among children., Implication: Findings suggest that child bullying should be approached with customized treatment considering their pattern of risk exposure., (Copyright © 2024 Elsevier Ltd.

Introduction: Childhood maltreatment, peer victimization, and borderline personality traits have all been shown to be linked to suicidal risk. However, there remains a need to illuminate the possible direct and indirect pathways among them from a developmental perspective that could serve as intervention targets. This study thus aimed to investigate the direct and indirect relationships among developmental trajectories of childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk in adolescents., Methods: A total of 1648 Chinese adolescents (48.12% boys; M age  = 13.69; SD = 0.82) in junior middle schools completed self-report measures on three-time points across 1 year. Latent growth curve modeling was used to evaluate the direct and indirect relationships among the developmental trajectories of the aforementioned study variables., Results: The developmental trajectories of childhood maltreatment, peer victimization, and borderline personality feature were positively and directly related to the developmental trajectory of suicidal risk; and the developmental trajectories of childhood maltreatment, peer victimization were indirectly related to the developmental trajectory of suicidal risk through the mediating effect of the developmental trajectory of borderline personality feature., Conclusions: The findings elucidated the direct and indirect longitudinal relationships among childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk, highlighting that interventions should target childhood maltreatment, peer victimization, and borderline personality feature to decrease suicidal risk in adolescents with a developmental perspective., (© 2024 Foundation for Professionals in Services to Adolescents.)

Abstract: Bullying victimization has been identified as a significant factor influencing academic outcomes. We sought to evaluate the educational outcomes and psychiatric comorbidities in children and adolescents who are victims of bullying using the National Survey of Children's Health dataset for the study. The participants were children and adolescents (age: 6-17 years) categorized into two groups: group 1, not bullied ( n = 21,015), and group 2, bullied more than once ( n = 21,775). Individuals whose health status was fair or poor have experienced more bullying (2.4% vs . 1.4%, p < 0.001). Individuals in the group 2 were more likely to repeat the grades than the group 1 (7.1% vs . 5.9%, p = 0.039). Individuals who were missing ≥11 school days and sometimes or never engaged in school were observed to be more in the group 2 compared with the group 1 (5.9% vs . 3.2% and 20.3% vs . 10.6%, p < 0.001). In conclusion, bullying victimization could be a risk factor and associated with decreased academic outcomes., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Previous studies have identified the association between classroom social status and bullying victimization, but it remains unclear how different victimization trajectories relate separately to social status dimensions: preference (acceptance and rejection) and popularity (popular and unpopular), and whether there are differences between victimization trajectory groups. This study assumed a longitudinal approach to explore these research questions., Method: A total of 3.182 (50% girls; M = 12.55 years at wave 1) students participated in the study., Results: Four bullying victimization trajectory groups were found: high, decreasing, increasing and low in victimization. Multigroup analyses showed that high in victimization group had the worst acceptance, rejection, and unpopularity indexes. The decreasing victimization group increased in acceptance and popularity, whereas the increasing victimization group increased in rejection and popularity., Conclusions: These results underline the importance of considering the different dimensions of social status and their association with victimization trajectories when anti-bullying programs are proposed.

Introduction: Bullying is a widespread public health issue, found in different contexts (e.g. schools, universities, workplaces, families), and it has negative consequences on both the perpetrator and the victim. There is a lack of studies addressing bullying among university students in Arab countries and more specifically in Lebanon. The objective of our study was to determine the prevalence of bullying among a sample of university students in Lebanon, its forms, and associated factors., Methods: The study consists of a cross-sectional online survey addressed to university students in Lebanon that evaluates sociodemographic data, presence and type of bullying, history of bullying during childhood, adverse childhood experiences, daily life functioning, and mental health status (reported psychiatric disorders, substance use, self-harming behaviors, and suicidal attempts). Chi-Square and Fisher's exact tests were used to compare the results between victims of bullying and the rest of the sample., Results: Three hundred and twenty-seven university students participated in this study. The prevalence of bullying was 14.1%. The main forms of reported bullying were verbal (58.7%) and social bullying (65.2%). The main associated factors were being a witness of bullying at university (84.8% vs. 56.2% - P<.001) and history of cyberbullying (13% vs. 4.6% - P=.024). Among students who reported current bullying, 28.3% had a psychiatric diagnosis, 19.6% reported substance use, 15.2% had self-harming behaviors, and 8.7% had suicide attempts. Victims of bullying in the university reported a significant negative impact on their daily lives (lack of interest in daily activities, academic decline) (83.7%) and mental health concerns (psychiatric disorders, substance use, suicide attempts) (88.4%)., Conclusion: Even though bullying is an event less experienced in university than in school, it is nevertheless still present with potential negative impact on the victims. Bullying in a university setting is a public health issue that could benefit from more studies as well as prevention and intervention programs., (Copyright © 2023 L'Encéphale, Paris.

School bullying represents a widespread expression of violence in the peer context. Guided by the social-ecological model, this study investigated the longitudinal and transactional pathways linking domestic and neighborhood/community violence exposure (through direct victimization and witnessing), self-serving cognitive distortions (CDs), and school bullying perpetration. Furthermore, consistent with the previous literature, we tested the cognitive desensitization process that could develop in response to chronically violent contexts. Two four-wave cross-lagged panel mediation models were tested in a sample of 778 high school students (28.1% males; M age [Time 1; T1] = 14.20, SD = 0.58). The results showed differential effects of multiple contexts and forms of violence exposure, with domestic violence victimization and community violence witnessing being associated with self-serving CDs and bullying perpetration over time. Moreover, significant associations between CDs and bullying perpetration over time were found, with bidirectional effects for each of these longitudinal patterns. Finally, self-serving CDs significantly mediated the relationships between both domestic violence victimization and community violence witnessing and school bullying perpetration. These findings highlight the need to consider school bullying as a social phenomenon stemming from a complex and bidirectional interplay between individuals and the environments they inhabit, confirming a basic postulate that "violence breeds violence".

This study aims to analyze the association between bullying behaviors, adverse childhood experiences and social capital in late adolescence. Secondary school students aged 15-19 of a metropolitan region of Brazil were recruited for a sectional epidemiological survey, with a sample of 2,281 students, stratified by municipality of school location. Descriptive and inferential statistics were performed from three instruments: Olweus Bully/Victim Questionnaire, Childhood Adversity History Questionnaire and Integrated Questionnaire to Measure Social Capital, in adapted versions. The results showed that the factors associated with bullying victims were gender and adversity in childhood. The factors associated to bullying aggressors were gender, childhood adversities, and cognitive social capital. And the factors associated with bullying aggressor-victims were gender, childhood adversities, and cognitive social capital. It is concluded that bullying is associated with adversity in childhood and also with cognitive social capital and they point out the need to address the causes of violence in order to provide a healthy and safe development for children and adolescents, preventing negative outcomes for physical and mental health.

Background: Though separate bodies of research have shown sexual and gender minority (SGM) youth, and youth with disabilities, separately, face distinct social and health disparities, little is known about youth who both identify as SGM and have disabilities., Objective: The current study examined differences in wellbeing among SGM youth by disability category (i.e., physical, developmental, psychiatric) across victimization, bullying, dating violence, school safety, and experienced stress., Methods: Using self-reported data from 9418 SGM youth aged 13-17 in the United States, multivariate linear regressions were conducted to examine how stress and social safety experiences varied across disability status., Results: Compared to SGM youth without a disability, SGM youth across all disability categories (physical, developmental, psychiatric) had greater odds of LGBT- and disability-based victimization, greater average stress, as well as lower levels of school safety. SGM youth with any disability, physical disability, or psychiatric disability also had greater odds of dating violence compared to SGM youth without a disability., Conclusion: SGM youth with disabilities may be in particular need of targeted programs that address both disability and sexual/gender identities, and may benefit from increased supports across developmental contexts (e.g., against bullying in school). Stakeholders should consider how such support can be improved, tailored, and implemented, for SGM youth and the diversity of disabilities they have., (Published by Elsevier Inc.)

The involvement of left-behind children (LBC) in school bullying has raised concern in China. However, the susceptibility of LBC to engage in bullying is controversial, and comprehensive, representative studies covering the entire country are lacking. The purpose of this study was to evaluate the prevalence and severity of school bullying among LBC. The Chinese National Knowledge Network, WanFang, VIP, PubMed, Web of Science, EMBASE, and EBSCO databases were searched for literature on being left-behind and bullying before April 2022. The effect size was measured by odds ratio (ORs), standard mean difference (SMD), and 95% confidence interval (CI). Random-effects or fixed-effects models were selected for meta-analysis, and subgroup analysis was used to explore the sources of heterogeneity. The meta-analysis included 25 studies of school bullying among LBC and non-LBC (NLBC). The prevalence of bullying perpetration and victimization among LBC were 18.58% (95% CI [3.72%, 33.44%], p  < .05) and 40.62% (95% CI [25.47%, 55.78%], p  < .05), respectively. Compared with NLBC, the risk of bullying perpetration and victimization among LBC increased 1.97 times (OR = 1.97, 95% CI [1.77, 2.20], p  < .05) and 2.17 times (OR = 2.17, 95% CI [1.43, 3.29], p  < .05), respectively. The severity of bullying experienced by LBC was higher than that of NLBC (SMD = 0.49, 95% CI [0.20, 0.79], p  < .05). The prevalence and severity of school bullying were higher in LBC than in NLBC, and left-behindness was positively associated with school bullying. LBC are a crucial population to protect when developing bullying interventions., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The association between childhood bullying victimization and depression has been well-explored among young adults, but little is known about whether this relationship persists into later life stages, specifically during middle-aged and older phases. Moreover, the intricate mechanisms underpinning this association and the potential existence of gender differences within this context remain inadequately elucidated. To address this gap in knowledge, this study aims to investigate the association between childhood bullying victimization and depression in later life, with a focus on exploring the mediating role of social isolation and the moderating roles of gender. A nationally representative sample of 5,070 individuals (mean age = 61.02, SD  = 9.48; male = 55%) was drawn from the China Health and Retirement Longitudinal Study. By employing the bootstrapping analysis method, the mediating role of social isolation was examined, and the moderating role of gender was tested through the generation of interaction items. The results reveal a significant association between childhood bullying victimization and severe depression in later life. Additionally, social isolation plays a mediating role in this association between childhood bullying victimization and social isolation, and the association between social isolation and depression, as well as the relationship between social isolation and depression, are both moderated by gender, presenting stronger effects for female groups than for male groups. However, no moderating role of gender is found in terms of the direct association between childhood bullying victimization and depression. These findings highlight the fact that childhood bullying is not only a problem in the immediate term but also a concern that affects individuals across entire life course. This study has implications for healthcare in proactively investigating, diagnosing, and treating depression by inquiring about childhood bullying victimization experiences. Furthermore, intervention policies that aim to reduce social isolation may be particularly beneficial in mitigating the negative associations, especially for female individuals., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Purpose: This population-based cohort study aimed to examine the association with childhood attention deficit/hyperactivity disorder (ADHD) and bullying experiences during adolescence among Digital Generation individuals, exploring both traditional and cyberbullying., Methods: This study included data from 15,240 participants, collected from the Taiwan Adolescent to Adult Longitudinal Study project. Participants, initially in seventh and 10th grade in 2015, were selected through a multistage stratified sampling approach. Self-report questionnaires assessed traditional and cyberbullying victimization experiences during adolescence, with 5-year longitudinal follow-up. Childhood ADHD diagnoses were identified by linking data to Taiwan's National Health Insurance Research Database from 2000 to 2015. Logistic regression models were employed to examine the relationship between childhood ADHD and bullying victimization while controlling for relevant covariates., Results: Individuals diagnosed with childhood ADHD exhibited a significantly higher likelihood of experiencing bullying during adolescence (adjusted odds ratio (aOR) = 1.52, 95% confidence interval (CI): 1.28-1.80). This association extended to various forms of bullying, including physical (aOR = 1.42, 95% CI: 1.20-1.68), verbal (aOR = 1.42, 95% CI: 1.20-1.67), relational (aOR = 1.45, 95% CI: 1.22-1.71), and cyber (aOR = 1.35, 95% CI: 1.14-1.61). Additional factors positively associated with bullying victimization included male, binge drinking, and depression, while a positive campus atmosphere was protective against bullying. However, there is no evidence for interactions between these factors and ADHD in their associations with bullying., Discussion: Childhood ADHD increases the risk of both traditional and cyberbullying during adolescence. Recognizing this risk is essential for targeted interventions and further research on underlying mechanisms., (Copyright © 2024. Published by Elsevier Inc.)

This paper analyzed the role of depression as a mediator in the association between bullying, cyberbullying, and suicide risk in adolescent females. A total of 751 Colombian adolescent females (M= 13.71, SD=1.897), who were administered the Plutchik Suicide Risk Scale, the Beck Depression Inventory, the European Bullying Intervention Project Questionnaire and Cyberbullying. Bullying victimization and aggression and cyberbullying victimization were found to contribute statistically significant effects that explaining 22 % of the variance in depression. The variables of victimization in bullying and cyberbullying and depression explained 64 % of the variance in suicidal risk, and depression mediated the association between victim and aggressor roles in bullying and cyberbullying in predicting suicidal risk, whose total direct and indirect effects are statistically significant. The findings support the role of depression as a mediating variable between bullying and cyberbullying and suicidal risk in female adolescents and highlight the importance of focusing prevention and intervention efforts on risk factors for depression and suicidal behavior in cases of bullying and cyberbullying., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Research has documented trends in bullying victimization for sexually diverse adolescents in the US, but trends regarding school social unsafety are understudied and there is a dearth of research examining these trends for gender diverse adolescents. This study aimed to identify disparities in bullying victimization and feelings of social unsafety in schools for sexually and gender diverse adolescents. Data stem from the 2014 (N = 15,800; M age = 14.17, SD = 1.50), 2016 (N = 22,310; M age = 14.17, SD = 1.49), and 2018 (N = 10,493; M age = 14.02, SD = 1.52) survey cycles of the Social Safety Monitor, a Dutch cross-sectional school-based study. Findings indicate that sexual orientation disparities remained relatively small, but stable over time, while gender diverse adolescents remained more likely to be victimized and feel unsafe in school, with larger disparities overall. Monitoring these trends is highly relevant, especially considering recent negative developments regarding societal acceptance of sexual and gender diversity., (© 2024. The Author(s).)

Prevalence estimates of sibling bullying indicate it occurs more frequently and with more negative consequences than peer bullying, yet many countries do not track or investigate the phenomenon. University students from Argentina, Estonia, and the United States were surveyed to investigate their retrospective experiences involving sibling bullying, how often it occurred, the roles held, and the forms communicated. In the aggregated data, roughly 50 % of the sampled emerging adults (N = 3477) reported experience with sibling bullying, with the dual role of bully-victim being the most frequently reported role held by males and females, with the second role being bully for males and victim for females. Verbal forms of bullying were most frequently reported by males and females, with physical, relational, and technological forms occurring less frequently, indicating the importance of studying the messages conveyed during bullying incidents. Variations between biological sex, bullying role and form were detected that indicate siblings experience bullying in ways that are unique from peer bullying. Country comparisons revealed bullying frequencies varied among males and females, suggesting sibling bullying experiences are likely to be culturally influenced. More research is warranted to examine the negative impact bullying has on sibling psycho-social development and the potential transfer to non-familial relationships and contexts. Discussion of these findings and the implications for academics and practitioners alike is provided., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Background: Peer victimization predicts the development of mental health symptoms in the transition to adolescence, but it is unclear whether and how parents and school environments can buffer this link., Methods: We analyzed two-year longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study, involving a diverse sample of 11 844 children across the United States (average at baseline = 9.91 years; standard deviation = 0.63; range = 8.92-11.08; complete case sample = 8385). Longitudinal associations between peer victimization and two-year changes in mental health symptoms of major depression disorder (MDD), separation anxiety (SA), prodromal psychosis (PP), and attention-deficit/hyperactivity disorder (ADHD) were examined including a wide range of covariates. Mixed linear models were used to test for the moderating effects of parental warmth and prosocial school environment., Results: 20% of children experienced peer victimization. Higher exposure to peer victimization was associated with increases in MDD, SA, and ADHD symptoms. Parental warmth was associated with decreases in MDD symptoms but did not robustly buffer the link between peer victimization and mental health symptoms. Prosocial school environment predicted decreases in PP symptoms and buffered the link between peer victimization and MDD symptoms but amplified the link between peer victimization and SA and ADHD symptoms., Conclusions: Peer victimization is associated with increases in mental health symptoms during the transition to adolescence. Parental warmth and prosocial school environments might not be enough to counter the negative consequences of peer victimization on all mental health outcomes.

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.
