Bullying victimisation in adolescence: prevalence and inequalities by gender, socioeconomic status and academic performance across 71 countries

Cyberbullying through the lens of trauma: an empirical examination of US youth

BACKGROUND

Scholars have argued that cyberbullying should be characterized as an Adverse Childhood Experience (ACE) given its potential for traumatic impacts on youth development. Considering the current attention surrounding mental health and well-being among adolescents, it seems critical to empirically measure this relationship, and also determine if some types have a stronger negative influence.

METHODS

Data utilized in this study were derived from a survey conducted on a nationally-representative sample in 2023 involving 2,697 English-speaking middle and high school students aged 13 to 17 residing within the United States.

RESULTS

We identified a strong positive relationship between PTSD symptoms and experience with cyberbullying. Surprisingly, exclusion and rejection were just as harmful as overt threats when it comes to inducing trauma. Gossip and malicious comments were as detrimental as targeting someone based on their identity.

CONCLUSION

By becoming more trauma-informed and implementing school-based specific measures, those who work with youth can better safeguard and support them in the face of cyberbullying.

Mobile phone addiction was the mediator and physical activity was the moderator between bullying victimization and sleep quality

BACKGROUND AND OBJECTIVES

Bullying victimization is strongly associated with sleep quality issues in primary school students, yet the underlying mechanisms among these variables require further exploration. This study investigates the mediating role of mobile phone addiction and the moderating role of physical activity in the relationship between bullying victimization and sleep quality among primary school students, contributing to a deeper understanding of these psychological processes.

METHODS

This study utilized a convenience sampling method to recruit 502 primary school students in 2023. The sample included 232 boys and 270 girls, with ages ranging from 10 to 12 years (mean age = 11.15 ± 0.62). Participants were recruited from specific region or school district to ensure a diverse representation of the target population. Ethical approval was obtained from the relevant institutional review board, and informed consent was obtained from both the students and their parents or guardians prior to data collection.

RESULTS

Bullying victimization was significantly positively correlated with both sleep quality issues and mobile phone addiction. Additionally, mobile phone addiction was significantly positively correlated with sleep quality issues. The analysis confirmed that mobile phone addiction mediates the relationship between bullying victimization and sleep quality. Furthermore, physical activity was found to moderate the relationship between bullying victimization and mobile phone addiction.

CONCLUSIONS

This study elucidates the psychological mechanisms underlying the relationship between bullying victimization and sleep quality among primary school students. Mobile phone addiction serves as a mediating factor, while physical activity acts as a moderating factor in the link between bullying victimization and mobile phone addiction. These findings underscore the importance of addressing mobile phone addiction and promoting physical activity as part of targeted interventions to improve sleep quality among primary school students.

Bullying victimization and associated factors among school-aged adolescents in Africa: a systematic review and meta-analysis

BACKGROUND

Bullying victimization during school age is a global public health concern. School-aged adolescents experiencing bullying victimization are more likely to encounter physical, cognitive, and mental health issues; including greater rates of depression, anxiety, and suicidal behaviors. This systematic review and meta-analysis was conducted to estimate the pooled prevalence of bullying victimization and its determinants among school-aged adolescents in Africa.

METHODS

All studies reporting the prevalence of bullying victimization and its determinants among African school-aged adolescents were included based on the predefined eligibility criteria. We followed the Preferred Reporting Items for Systematic Review and Meta-Analysis(PRISMA), a guideline for reporting a systematic review and meta-analysis. A random-effects model was employed to estimate the pooled effect size of bullying victimization and its determinants with their odds ratio (OR) and a 95% confidence interval(CI). Funnel plots analysis and Egger's regression test were conducted to assess publication bias. Subgroup and sensitivity analyses were also performed.

RESULTS

Twenty-five studies involving 41,716 school-aged adolescents were included in this systematic review and meta-analysis. The overall pooled prevalence of bullying victimization among school-aged adolescents in Africa was 46.35%, with a 95% CI (41.45, 51.24). According to the subgroup analysis of the study region, 49.17% of bullying victimization was reported in the Eastern region of Africa whereas, 32.73% was reported in the Southern region. Engaging in physical fights [OR=1.86; 95% CI: 1.66, 2.07], current substance use [OR=1.85; 95% CI: 1.31, 2.62], feeling lonely [OR=1.98; 95% CI: 1.49, 2.65], and being worried [OR=2.56; 95% CI: 2.12, 3.1] were significantly associated with bullying victimization.

CONCLUSION AND RECOMMENDATION

This review revealed that the pooled prevalence of bullying victimization among school-aged adolescents in Africa was high. To ensure adolescents' mental health and cultivate productive manpower, fostering a supportive environment in schools is mandatory.

The central mediating effect of inhibitory control and negative emotion on the relationship between bullying victimization and social network site addiction in adolescents

BACKGROUND AND OBJECTIVES

Bullying victimization is strongly associated with social network site addiction among adolescents. However, the underlying mechanisms between these variables remain unclear. This study aims to explore the psychological mechanisms linking bullying victimization to social network site addiction by examining the mediating roles of depression, anxiety, stress, and inhibitory control.

METHODS

A self-report survey was conducted among a sample of 1,005 adolescents in China. The survey included measures of bullying victimization, social network site addiction, depression, anxiety, stress, and inhibitory control. Descriptive and correlational analyses were performed, followed by the construction of a chain mediation model.

RESULTS

Bullying victimization was significantly positively associated with social network site addiction. However, this relationship became non-significant when negative emotional states (depression, anxiety, stress) and inhibitory control were introduced as mediating variables. Specifically, bullying victimization significantly predicted negative emotional states and was negatively associated with inhibitory control. Negative emotional states were also negatively related to inhibitory control, while inhibitory control was negatively associated with social network site addiction. Among the negative emotional states, stress and anxiety showed a significant negative correlation with social network site addiction.

CONCLUSION

This study sheds further light on the psychological mechanisms linking bullying victimization and social network site addiction among adolescents. Depression, anxiety, stress, and inhibitory control act as mediating factors in this relationship. These findings highlight the importance of targeting these variables in understanding and developing interventions for social network site addiction among adolescents.

Peer victimization in early adolescence and maladjustment in adulthood

Studies report different effect sizes for associations between peer victimization and later maladjustment. A possible origin of this heterogeneity is the length of the interval between victimization and maladjustment assessments. Effect sizes might also vary as a function of reporter. Longitudinal data from TRAILS, a study of adolescents followed from age 11 to 29 (baseline n = 2229) were used to test whether peer victimization assessed from adolescents themselves, their parents, teachers, and peers predicted internalizing symptoms, thought problems, and somatic complaints at six follow-ups with a temporal distance of up to 19 years. Neither self- nor peer-reported victimization predicted later maladjustment. In contrast, parent-reported victimization stably predicted adult maladjustment. Teacher-reported victimization also predicted maladjustment but associations were weaker and largely non-significant when parent reports were accounted for simultaneously. Parent-reported peer victimization has traditionally played a minor role in bullying research as parents are usually not present when victimization occurs. The results of this study however suggest that parents should be listened to when talking about their offspring being victimized.

Linking Daily Victimization to Daily Affect Among Adolescents: The Mediating Role of Sleep Quality and Disturbance

Bullying victimization is prevalent among adolescents and often linked to emotional problems. Prior studies have been focused on the concurrent or longitudinal associations between bullying victimization and emotional problems, but the daily associations and the underlying mechanisms remain unclear. Implementing daily diary method, the study aimed to examine the links between daily victimization and positive and negative affect as well as the mediating role of sleep quality and disturbance. A total of 265 Chinese adolescents (Mage = 11.65, SD = 0.74; 32.80% females) participated in this study and completed 7-day daily diaries on bullying victimization (traditional and cyber victimization), sleep quality and disturbance, and affect. As hypothesized, at the between-person level, sleep disturbance mediated the relationships between both traditional and cyber victimization and subsequent negative affect. At the within-person level, sleep quality mediated the pathway between traditional victimization and next-day negative affect; furthermore, sleep disturbance mediated the pathway between traditional victimization and positive affect the following day. These findings highlight the mediating roles of sleep quality and sleep disturbance in the relationships between stressful victimizing experiences and emotional problems and also provide novel insights into these associations.

The moderating role of social media motives in the relationship between screen usage and cybervictimization

BACKGROUND

Screen time is on the rise among youth, and as a result, cyberbullying victimization has become increasingly prevalent. While prior research has established a positive correlation between screen usage and cyberbullying victimization, a paucity of research has explored how motives for screen usage are associated with cyberbullying victimization and moderate the positive association between screen usage and cyberbullying victimization.

OBJECTIVE

The present study sought to address these research gaps by exploring the association between motives for screen usage and cyberbullying victimization and examining whether these motives moderate the association between screen time and cyberbullying.

PARTICIPANTS AND SETTING

Data from 332 participants (mean age = 16.27 years; 25 % male) were collected in a longitudinal study. Participants were required to be aged 12-18, proficient in English, not currently in treatment for psychological issues, and own a smartphone.

METHODS

Participants installed a mobile sensing app to measure their screen usage over a four-week period objectively. Motives for screen usage were assessed using an adapted version of the Internet Motive Questionnaire for Adolescents. Cyberbullying experiences were self-reported during a follow-up assessment.

RESULTS

Coping (p < 0.01), conformity (p < 0.001), and enhancement motives (p < 0.05) were positively associated with cyberbullying victimization. Conformity motives moderated the relationship between screen time and victimization, with the association being strongest among youth with low conformity motives (p < 0.01).

CONCLUSIONS

These findings indicate that risky motives for screen usage are associated with a higher likelihood of experiencing cyberbullying victimization and that they moderate the association of screen time with cyberbullying.

Applicability of Retrospective and Prospective Gender Scores for Clinical and Health Data: Protocol for a Scoping Review

BACKGROUND

Gender is known to have a strong influence on human health and disease. Despite its relevance to treatment and outcome, gender is insufficiently considered in current health research. One hindering factor is the poor representation of gender information in clinical and health (meta) data.

OBJECTIVE

We aim to conduct a scoping review of the literature describing gender scores. The review will provide insights into the current application of gender scores in clinical and health settings. The protocol describes how relevant literature will be identified and how gender scores will be evaluated concerning applicability and usability in scientific investigations.

METHODS

Our scoping review follows the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. A title and abstract screening was conducted on PubMed, followed by a full-text screening. The inclusion and exclusion criteria were discussed by a team of 5 domain experts, and a data-charting form was developed. The charted data will be categorized, summarized, and analyzed based on the research questions during the scoping review.

RESULTS

We will report our research results according to the PRISMA-ScR guidelines. The literature retrieval was carried out on June 13, 2024, and resulted in 1202 matches. As of July 2024, the scoping review is in the data extraction phase and we expect to complete and publish the results in the first quarter of 2025.

CONCLUSIONS

The scoping review lays the foundation for a retrospective gender assessment by identifying scores that can be applied to existing large-scale datasets. Moreover, it will help to formulate recommendations for standardized gender scores in future investigations.

Breaking the Cycle: Perceived Control and Teacher-Student Relationships Shield Adolescents from Bullying Victimization over Time

BACKGROUND

Bullying victimization remains a grave issue in early adolescence. However, existing research often lacks a longitudinal perspective and sufficient attention to protective factors, particularly the dynamic role of teacher-student relationships.

OBJECTIVE

This study explores the longitudinal protective mechanisms against bullying victimization, focusing on the roles of perceived control and teacher-student relationships.

METHODS

A sample of 1454 adolescents (mean age = 13.63 years, SD = 0.76, 51% female) was followed over the course of one year. Latent growth models were employed to examine the developmental trajectories of bullying victimization, perceived control, and teacher-student relationships, and to investigate the longitudinal mediating role of teacher-student relationships in the relationship between perceived control and bullying victimization.

RESULTS

Both perceived control and teacher-student relationships showed a consistent increase over time, while bullying victimization declined over time. The intercept of perceived control negatively predicted the intercept of bullying victimization, with this relationship mediated by the intercept of teacher-student relationships. Furthermore, the slope of perceived control affected the slope of bullying victimization solely through the slope of teacher-student relationships.

CONCLUSIONS

These findings highlight that perceived control serves as a stable protective factor against bullying, while strong teacher-student relationships can further reduce bullying victimization. Enhancing students' perceived control and fostering supportive teacher-student relationships should be key components of anti-bullying interventions.

Bullying Victimization and Self-Harm Among Adolescents from Diverse Inner-City Schools: Variation by Bullying Sub-Types and the Role of Sex

OBJECTIVE

Bullying has consistently been highlighted as a risk factor for youth self-harm. Less is known about associations by bullying sub-type (i.e., physical, verbal, relational, cyberbullying), among boys and girls in diverse urban populations. This study aimed to explore: (1) prevalence of bullying and lifetime self-harm; (2) cross-sectional associations between bullying and self-harm. Both aims investigated bullying sub-types and the role of sex.

METHOD

Baseline data on bullying victimization and lifetime self-harm were drawn from REACH (Resilience, Ethnicity and AdolesCent Mental Health), an accelerated cohort study of adolescent mental health in London, United Kingdom. Data on baseline self-harm and sex were available for 3,060 adolescents aged 11-14 years (Mage=12.4, 50.6% girls, >80% ethnic minority groups) from 10 schools.

RESULTS

Prevalence of bullying in the past six months was 22.3% and lifetime self-harm was 16.9%. Both were more common in girls than boys (adjusted risk ratios: bullying, 1.13 [1.02,1.25]; self-harm, 1.45 [1.03,1.86]). By bullying sub-type, prevalence estimates ranged from 4.1% (cyberbullying) to 16.6% (physical bullying). Bullying was associated with self-harm (aRR 3.35 [2.89,3.82]) for both girls (aRR 3.61 [3.07,4.14]) and boys (aRR 2.96 [2.27,3.65]), independent of sex, age, free school meals and ethnic group. All sub-types were associated with self-harm (aRRs 3.16-4.34), for girls and boys.

CONCLUSIONS

These baseline findings underline the importance of exploring nuances between bullying sub-types and self-harm, by sex or gender.

Social anxiety and bullying victimization: A three-level meta-analysis of cross-sectional and longitudinal studies

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.

Global, regional, and national burden of bullying related mental disorders of adolescent from 1990 to 2019: A systematic analysis for the Global Burden of Disease Study 2019

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.

Prevalence and associated factors of school bullying among adolescents in Inner Mongolia, China

Background

Although studies in China have found that school bullying is prevalent among adolescents, most relevant research has focused on southern China, while research in northern China is limited. This study aimed to explore ethnic disparities in the socio-demographic determinants of school bullying in Inner Mongolia, a northern region of China.

Methods

A cross-sectional study was conducted among 2891 adolescents in Inner Mongolia, China, from September to December 2022. Data on participants' sociodemographic characteristics and school bullying experiences were collected through questionnaires. Multivariate logistic regression analyses, stratified by ethnicity, were employed to examine factors associated with school bullying. Furthermore, subgroup analyses and interaction tests were conducted to explore potential effect modifiers of the relationship between ethnicity and bullying.

Results

The prevalence of school bullying was 18.99 % (549/2891) overall, with 17.96 % (420/2339) among Han and 23.37 % (129/552) among ethnic minorities. Minority adolescents faced a higher risk of bullying compared to Han (OR = 1.35, 95 % CI: 1.08-1.69, P < 0.05). Middle school students were more vulnerable to bullying than high school students (OR = 1.25, 95%CI:1.03-1.52, P < 0.05). Among Han adolescents, having a mother with high school education was protective against bullying (OR = 0.71, 95 % CI: 0.54-0.93, P < 0.05), while it was an associated factor for minorities (OR = 2.06, 95%CI:1.23-3.46, P < 0.05). Good family economic status was an associated factor for bullying among Han (OR = 1.62, 95%CI: 1.11-2.36, P < 0.05), but not among minorities. Belonging to other family structures (remarriage/foster family, intergenerational families, live with relatives and elders) was an associated factor for minorities (OR = 2.60, 95 % CI: 1.37-4.92, P < 0.05), but not for Han. Subgroup analyses revealed significant ethnic disparities in bullying experiences among middle school students, those from nuclear family, other family, and fair economic backgrounds (all P < 0.05). Interaction effects between ethnicity and these variables were not significant (all P > 0.05).

Limitations

This cross-sectional study has limitations in establishing causal relationships between identified associated factors and school bullying.

Conclusions

Ethnic minority adolescents in Inner Mongolia, China, especially middle school students, face a higher risk of school bullying than their Han peers. The differential impact of maternal education, family economic status, and family structure on bullying risk between Han and minority adolescents underscores the need for culturally sensitive, targeted interventions that consider the unique challenges faced by ethnic minority students.

Peer Bullying and Psychiatric Diagnoses in Adolescents with Nonsuicidal Self-Injury

OBJECTIVES

The aim of this study was to determine the comorbid psychiatric diagnoses, peer bullying rates and NSSI characteristics in adolescents who engage in self-injuring behavior.

MATERIALS AND METHODS

This case-controlled cross-sectional study was conducted between 1 March 2020 and 1 May 2021 in the Child and Adolescent Psychiatry and Paediatrics outpatient clinic of a hospital in the Southeastern Anatolia region of Turkey. The data of 50 adolescents with NSSI and 60 adolescents without NSSI attending school were compared. The data in the study were obtained using sociodemographic form prepared by the researchers, the Affective Disorders and Schizophrenia Interview Schedule for School-Age Children-Present and Lifetime Version-Dsm-5, Peer Bullying Scale Adolescent Form and Self-Injurious Behaviour Assessment Inventory.

RESULTS

Fifty adolescents (70% female) with a mean age of 15.4 years (S.D. = 1.4) with NSSI were included as case group and 60 adolescents (66.7% female) with a mean age of 15.5 years (S.D. = 1.3) without NSSI were included as control group. Banging/hitting self was the most common NSSI method, while affect regulation was the most common function. In the case group, verbal, isolation and damage to belongings among the victim subtypes in the last year were found to be significantly higher than in the control group. It was found that there was a positive correlation between the variety of self-injury methods and bullying exposure scores in adolescents with NSSI. Depression disorders, anxiety disorders, oppositional defiant disorder, attention deficit hyperactivity disorder, conduct disorder, and post-traumatic stress disorder diagnoses were found to be more prevalent in the group with NSSI.

CONCLUSIONS

Based on the finding, it was found that psychiatric diagnoses are more common in adolescents with NSSI, peer bullying subtypes are seen at a higher rate, and as bullying scores increase, the variety of NSSI methods also increases. It is thought that providing psychiatric evaluation and treatment for adolescents with NSSI, establishing cooperation with school and family for peer bullying, developing preventive mental health policies and effective intervention programmes may be beneficial.

How receiving welfare assistance could be linked to children's bullying victimization: Exploring the potential pathways

The study proposes and tests the pathways from receiving welfare assistance to children's bullying victimization. Specifically, the study examines whether children's difficulty making friends and school disconnection mediate the association between welfare assistance receipt to children's bullying victimization. The 2019 National Survey of Children's Health dataset was used, and the sample consisted of 12,230 caregivers of adolescents, aged 12-17 years. A path model was utilized to explore the proposed pathways. Findings suggest that welfare assistance receipt was not significantly associated with children's bullying victimization. It was positively related to children's bullying victimization through the mediating roles of having difficulty making friends and school disconnection. Schools and communities need to create spaces where youth can connect with peers, which is an important part of their development.

Risk Factors Associated With Bullying in Context of a Territory Exposed to Armed Conflict: A Cross-sectional Study

School violence and bullying are current and problematic events during adolescence. They are likely to have a marked presence in places highly exposed to armed conflict and violent environments, representing a double public health problem. The study aims to estimate the prevalence of different types of school violence perpetrated and experienced by school adolescents in a community with a history of exposure to armed conflict. Two thousand one hundred eighty-five school adolescents from a municipality in Colombia (males = 54.1%, 14-16 years = 38.6%) participated in the study. Nine educational institutions were included. A systematic random sampling was designed, with a proportional allocation of 35% within each school year from sixth to eleventh grade. The School Coexistence and Circumstances Affecting it-ECECA survey was applied. The prevalence and risks of bully and bullying were estimated. RRa were calculated with the 95% confidence interval adjusted for the other confounding variables. Analyses were constructed from generalized linear models, under the Poisson family and a logarithmic link function. We found a 9.3% of bullying victimization and a 3.5% prevalence of bully. A higher risk of bully was found among males, persons between 10 and 14 years of age, residents of rural or urban dispersed areas, residents of violent neighborhoods, alcohol consumers at school, and victims of aggression in childhood (RRa > 1.0, p-values <.05). The risk of victimization of bullying was higher in students younger than 15 years old, as residents of urban areas, having a history of childhood aggression, suffering abuse by a close person, and as alcohol users at school. This study provides evidence of risk factors for aggression and bullying that have implications for possible prevention measures in multiple social domains, including the individual, the family, and the school environment.

Childhood adversity in a youth psychiatric population: prevalence and associated mental health problems

Background: Childhood adversity can have lasting negative effects on physical and mental health. This study contributes to the existing literature by describing the prevalence rates and mental health outcomes related to adverse childhood experiences (ACEs) among adolescents registered for mental health care.Methods: Participants in this cross-sectional study were youths (aged 12-18 years) who were referred to outpatient psychiatric departments in the Netherlands. Demographic information was collected from the medical records. The Child Trauma Screening Questionnaire (CTSQ) was used to examine the presence of ACEs and posttraumatic stress symptoms (PTSS). To assess mental health problems, we used the Dutch translation of the Youth Self Report. Descriptive statistics and frequencies were used to calculate prevalence rates across the various ACEs domains. ANOVA and chi-square tests were used to explore the relationship between ACEs and mental health.Results: Of the 1373 participants, 69.1% reported having experienced at least one ACE and 17.1% indicated exposure to four or more ACEs in their lives. Although there was substantial overlap among all ACE categories, the most frequently reported were bullying (49.2%), emotional abuse (17.8%), physical abuse (12.2%), and sexual abuse (10.1%). Female adolescents (72.7%) reported significantly more ACEs than their male counterparts (27.0%). Furthermore, a higher number of ACEs was associated with significantly more self-reported general mental health problems, an elevated prevalence of both mood and post-traumatic stress disorders, and a greater presence of two or more co-existing psychiatric diagnoses (comorbid psychiatric classification).Conclusions: This cross-sectional study on childhood adversity and its association with mental health showed that ACEs are highly prevalent in youth registered for mental health care. This study provides support for a graded and cumulative relationship between childhood adversity and mental health problems.

The Relationship between a Competitive School Climate and School Bullying among Secondary Vocational School Students in China: A Moderated Mediation Model

School bullying is widespread in countries around the world and has a continuous negative impact on the physical and mental health of students. However, few studies have explored the influence mechanism of a competitive school climate on school bullying among Chinese secondary vocational school students. This study aims to explore the relationship between a competitive school climate and bullying in secondary vocational schools in the Chinese context, as well as the mediating role of school belonging and the moderating role of gender. Logit regression analysis and a moderated mediation model were used to analyze 1964 secondary vocational students from China based on PISA 2018 data from Beijing, Shanghai, Zhejiang, and Jiangsu, China. (1) The detection rate of school bullying in secondary vocational schools in China is 17.8%, lower than the world average. (2) A competitive school climate is significantly and positively correlated with secondary vocational school students' exposure to school bullying. (3) A moderated mediation model suggests that school belonging is an important mechanism by which a competitive school climate influences the occurrence of school bullying, whereas gender moderates the direct effect of a competitive school climate and the indirect effect of school belonging, which mitigates the negative effects of a competitive school climate to some extent. The research results show that creating a healthy competitive climate in schools, cultivating students' sense of belonging, and facing up to gender differences are helpful to prevent school bullying in secondary vocational schools.

Thoughts of self-harm in adolescents: Relationship with violence in the Dominican Republic

Violence against adolescents is a pressing health problem with long-term implications for future physical and mental well-being, such as thoughts of self-harm, which have been associated with suicidal ideation and completion. However, much of the research has been conducted only in high-income countries. This study aimed to examine the correlation between violence against adolescents and self-harm thoughts in La Romana, Dominican Republic (DR). Cross-sectional survey data was collected at a community-based clinic from participants aged 13-20. Participants were recruited through the clinic's adolescent program and peer referral, and verbal consent was obtained. A survey solicited information about each participant's demographics, experiences with violence, and thoughts of harm to self or others. The survey was completed by 49 adolescents. The mean age was 16.78 (SD 2.34); 65% were female. We performed t-tests and Fisher's exact to investigate the relationship between demographics, reported violence experiences and having self-harm thoughts. About half (45%) had experienced physical violence, 76% had experienced emotional violence, and 12% had experienced sexual violence. The most common perpetrators of physical and emotional violence were classmates (12% and 24%), and the most common perpetrator of sexual violence was an ex-partner (4.1%). Ten participants (20.4%) had thought about harming themselves. Self-harm thoughts were significantly associated with being female (p = 0.025), employed (p = 0.05), and to a higher number of experiences of physical (0.029) and sexual violence (p = 0.023). The results of this study suggest a high prevalence of both violence and self-harm thoughts in adolescents in the DR. Interventions that address physical and sexual violence against adolescents may be particularly important. Particular attention should also be paid to screening for self-harm thoughts in female-identifying adolescents. Further research is needed to better understand the relationship between violence and self-harm thoughts in adolescents in the DR.

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

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

Longitudinal associations between traditional and cyberbullying victimization and depressive symptoms among young Chinese: A mediation analysis

BACKGROUND

The impacts of bullying victimization on psychological health are long-lasting. However, the longitudinal mediating processes of the association between being bullied (traditionally and in a cyber context) and depressive symptoms of Chinese youth remain underexplored, including across the sexes.

OBJECTIVE

This study investigated the longitudinal association between bullying victimization and depressive symptoms, including the mediating effects of physical health, healthy lifestyles, sleep quality, and academic achievements. Different pathways from traditional bullying and cyberbullying victimization regarding depressive symptoms were also explored, with a comparison across the sexes.

PARTICIPANTS AND SETTING

Data were obtained from the China Education Panel Survey, and ninth graders aged approximately 15 years constituted the baseline cohort.

METHODS

The baseline data and longitudinal data at two- and five-year follow-ups, respectively, were evaluated to estimate structural equation models.

RESULTS

Baseline traditional bullying and cyberbullying victimization significantly predicted subsequent depressive symptoms at both follow-ups (P < 0.001). Being bullied also predicted worse healthy lifestyles, poorer sleep quality, and lower academic achievements (P < 0.05), all significantly correlated with the development of depressive symptoms (P < 0.001) regarding both bullying victimizations. Physical health was the mediator of the traditional bullying victimization-depressive symptoms linkage (P < 0.05). Female victims have a relatively higher risk of depression versus male victims, with different mediating pathways from victimization to depressive symptoms.

CONCLUSIONS

Our findings strengthen the evidence of a longitudinal association between bullying victimization and depressive symptoms, provide new explanations for mechanisms of mediation, and highlight the importance of long-term comprehensive mental health interventions for victims of bullying.

Adolescent Loneliness in 70 Countries Across Africa, America, and Asia: A Comparison of Prevalence and Correlates

PURPOSE

Emerging studies address adolescent loneliness a public health problem due to its negative associations with adverse health. However, evidence concerning adolescent loneliness and its correlation in nonwestern, low- and middle-income countries is scarce. This study examined the prevalence of loneliness and its correlates (i.e., sex, bullying victimization, and peer support) across 70 countries from five WHO regions.

METHODS

Data were collected from the Global School-based Student Health Survey of children aged 13-17 (2003-2018) years. Loneliness was defined as feeling lonely most of the time or always in the past 12 months based on self-reports. The prevalence of loneliness was estimated, and multivariable logistic regression ascertained prevalence ratios of correlates by country. Meta-analysis was used to examine regional and overall pooled estimates.

RESULTS

Among the 248,017 students included in the study, the overall prevalence of loneliness was 11.7% (95% confidence interval (CI): 10.6-12.7), with significant variations across countries. Girls (vs. boys prevalence ratio (PR = 1.4 95% CI: 1.3-1.4), students who experienced bullying victimization (PR = 2.2, 95% CI: 2.1-2.3), and students who reported a lack of close friends (PR = 1.8, 95% CI: 1.7-1.9) were at increased risk of experiencing loneliness. There was significant heterogeneity between countries for sex and lack of close friends but not for bullying victimization.

DISCUSSION

Adolescent loneliness is prevalent globally, especially in Africa and the Eastern Mediterranean. The considerable heterogeneity in its prevalence and correlates suggest that tailoring to the country context may benefit policy initiatives. Bullying may be a common intervention target in all countries.

The longitudinal course of childhood bullying victimization and associations with self-injurious thoughts and behaviors in children and young people: A systematic review of the literature

INTRODUCTION

Bullying victimization has consistently been highlighted as a risk factor for self-injurious thoughts and behaviors (SITBs) in young people. This systematic review of prospective, community-based studies explored associations between bullying victimization (traditional/face-to-face and cyber) across the full spectrum of self-harm and suicidality, in children and young people aged up to (and including) 25 years. Importantly, associations by sex/gender were explored.

METHODS

MEDLINE, Embase, PsycINFO, CINAHL and Scopus were searched for articles meeting the inclusion criteria. Articles were screened by title, abstract and full text. Quality appraisal was performed using the Newcastle-Ottawa Scale for cohort studies. Data were synthesized narratively. The protocol is registered on PROSPERO (CRD42021261916) and followed PRISMA 2020 guidelines.

RESULTS

A total of 35 papers were included, across 17 countries. Results were presented by bullying type: traditional/face-to-face (n = 25), cyber (n = 7) and/or an aggregate of both types (n = 7). Outcomes included suicidal ideation (n = 17), self-harm (n = 10), suicide attempt (n = 4), NSSI (n = 4), other (n = 7). Studies measured outcomes in under 18s (n = 24), 18-25-year-olds (n = 8) and both under 18s and 18-25-year-olds (n = 3). Studies exploring the role of sex/gender (20%) found some interesting nuances.

CONCLUSIONS

Some weak to strong associations between bullying and SITBs were found yet conclusions are tentative due to study heterogeneity (e.g., methods used, conceptualizations and operationalisations of exposures/outcomes). Future research should address methodological issues raised in this review, and further explore gender differences in bullying, including by bullying sub-types (e.g., overt or relational) and victim status (e.g., victim or bully-victim).

Prevalence and impact of peer victimisation among youth seeking treatment at a tertiary psychiatric institution in Singapore: a cross-sectional study

BACKGROUND

Peer victimization is common among adolescents and leads to negative consequences. However, few studies have examined the extent of peer-victimization and its correlates among adolescent patients in a psychiatric setting. The current study aimed to examine the prevalence and correlates of peer victimisation among youth with mental illness and to examine its association with depressive symptoms and health-related quality of life (HRQOL).

METHODS

A sample of 239 youths aged 15-24 years were recruited from the outpatient clinics of a tertiary psychiatric hospital in Singapore using convenience sampling. All participants were administered the Multidimensional Peer Victimisation Scale (MPVS), Short Form 12 (SF-12) questionnaire and the Patient Health Questionnaire-8 (PHQ-8). The effect of MPVS  total and subscores on depression scores, quality of life subscores and quality of life total scores were examined using multiple linear regression analyses.

RESULTS

The majority of the patients reported that they had experienced at least one form of peer victimisation (95.8%, n = 229) during their school years. Higher levels of 'verbal victimisation', 'attacks on property' and higher total MPVS scores were significantly associated with lower social functioning; additionally, higher levels of 'verbal victimisation' were significantly associated with lower mental component summary scores in the quality of life assessment. Higher scores on all four subscales as well as higher total scores on the MPVS were significantly associated with more severe depressive symptoms.

CONCLUSIONS

Given the high prevalence of peer victimisation in our sample and its associations with more severe depressive symptoms and lower quality of life, it is vital to implement interventions that prevent peer victimisation in educational and other social settings and to provide youth with strategies to more effectively manage instances of peer victimisation.

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.

Associations between experienced aggression, poor sleep, and suicide risk among Chinese adolescents

STUDY OBJECTIVES

The physical and mental health of adolescents is an important study area. This study aims to examine the occurrence of aggression, sleep disturbances, and suicide risk among Chinese adolescents, along with the relationships between these factors.

METHODS

This is a cross-sectional study conducted through an online survey. Of the original 7011 Chinese adolescent respondents, the analysis included data from 6122 adolescents, aged between 12 and 18 years, from 23 regions, whose average age was 16.12 (±1.44) years, with 48.8% being male. While the chi-square test and t-test were used for analyzing demographic data and continuous variables, respectively, mediation analysis was used to explore the mechanism of experiencing aggression on suicide risk. The respondents' sleep quality, nightmare distress, daytime sleepiness, fatigue, and suicide risk were assessed using the Pittsburgh Sleep Quality Index (PSQI), Nightmare Distress Questionnaire-Chinese version (NDQ-CV), Chinese Adolescent Daytime Sleepiness Scale (CADSS), Multidimensional Fatigue Inventory (MFI-20), and the suicide risk module of the Mini-International Neuropsychiatric Interview (MINI), respectively. Four items were used to assess adolescents' experiences with aggression.

RESULTS

Of the respondents, 42% reported experiencing aggression by others, especially parental physical maltreatment. Furthermore, 26.9% of adolescents in school, and in particular, 31.8% in senior high school experienced insomnia symptoms. Adolescents who reported experiences of aggression had more severe insomnia symptoms, nightmare distress, fatigue, and a higher risk of suicide when compared with those who did not (all ps < 0.001). Insomnia symptoms, nightmare distress, and fatigue all mediated the relationship between aggression and suicide risk, and there was a chain of mediating effects between these factors [for total indirect effect β = 1.1512, 95% CI (0.9671 to 1.3426), direct effect β = 0.4934, 95% CI (0.1978 to 0.7891), and total effect β = 1.6446, 95% CI (1.3479 to 1.9414)].

CONCLUSIONS

Our findings indicate that among adolescents, experiencing aggression is associated with an increased suicide risk. In addition to the direct effect of aggression on suicide risk, insomnia, nightmare distress, and fatigue mediate the relationship between aggression and suicide risk. More attention should be paid to adolescents experiencing aggression, and interventions should be implemented and strengthened.

Relationship between Emotional Intelligence, Victimization, and Academic Achievement in High School Students

The study of bullying implies analyzing the emotional competences of students, and it has been demonstrated that this phenomenon is due to the poor management of emotions. This study explores whether high scores in Emotional Intelligence (EI) are positively related to academic performance and negatively to bullying. The sample composition focused on students of Compulsory Secondary Education, formed by 3451 subjects aged between 11 and 18 years (50.88% women and 49.12% men). The selection of the high schools was made for non-random convenience, administering Peer Bullying Questionnaire (CAI), TMM-24 and school grades. To analyze the results, a model of structural equations was used by estimating the maximum likelihood together with the bootstrapping procedure. We concluded that EI stands as a protector against bullying and has a positive impact on academic performance. This infers that having greater clarity, repair and emotional attention correlates with a lower possibility of being bullied, at the same time, a school climate without aggressiveness generates positive links towards the school and towards optimal learning environments.

The mental health of children and young people living in big cities in a revolving postpandemic world

PURPOSE OF REVIEW

The world's population is increasingly urban, with most children and young people growing up and living in cities. Evidence suggests that urbanicity is linked to an increased risk for the development of mental health disorders. Rather than an accumulation of risk factors, urbanization is a complex process that profoundly structures living conditions. In this sense, it is timely to discuss what are the social and structural determinants of mental health of children and young people in such settings.

RECENT FINDINGS

Three domains of determinants of mental health were selected for discussion: economics and living conditions, crime and violence, and urban layouts. For each, we debated realities faced by urban children and young people, providing an overview of recent evidence on implications for mental disorders and well being. We also discuss the potential impacts of the covid-19 pandemic on each domain, as well as recommendations for future action.

SUMMARY

Structural factors are of major relevance for the mental health of children and young people living in cities. The agenda of mental health promotion and prevention must include whole-of-society interventions aimed at improving living conditions, including economic and social capital, violence prevention and urbanistic planning.

Homicidal ideation and psychiatric comorbidities in the inpatient adolescents aged 12-17

OBJECTIVES

Adolescents with a homicidal tendency is a growing concern in the United States. Studies in the past have showcased the relationship between homicidal ideation (HI) and psychiatric illnesses, but very limited information is available on the adolescent and inpatient population. We aim to evaluate the prevalence of demographic characteristics and psychiatric disorders in adolescents with and without HI.

MATERIALS AND METHODS

Adolescent (age 12-17) population admitted to the hospital with the diagnosis of homicidal ideation was identified from the 2016-2018 National Inpatient Sample Dataset (NISD). Patients without HI were defined as the control group. The prevalence of psychiatric comorbidities between the groups was compared by applying the Rao-Scott adjusted chi-square test. We used multivariable logistic regression to generate odds ratio (OR) of homicidal ideation as an outcome; we adjusted age, sex, race, socioeconomic status, substance use disorders, alcohol use disorders, and psychiatric comorbidities.

RESULTS

A total of 18,935 patients (mean age: 14.5) with HI diagnosis were identified in this study. Majority of the patients were male subjects in the HI group compared to the control group (58.7 vs. 41.2%, p < 0.001). Racially, HI was more prevalent in white race (56.0 vs. 52.6%, p < 0.001) and black race (22.3 vs. 17.8%, p < 0.001), compared to Hispanic race (14.9 vs. 21.3%, p < 0.001). Major depression (Odds ratio [OR]: 2.66, p < 0.001), bipolar disorder (OR: 3.52, p < 0.001), anxiety disorder (OR: 1.85, p < 0.001), ADHD, and other conduct disorders (OR: 4.01, p < 0.001), schizophrenia (OR: 4.35, p < 0.001) are strong predictors of HI. Suicidality was prevalent in 66.9% of patients with HI.

CONCLUSION

We found a higher prevalence of psychiatric illnesses such as depression, anxiety, and bipolar disorder in adolescents with homicidal ideation in the inpatient setting. White and black races were more prevalent in patients with homicidal ideation. Further large-scale longitudinal research studies are warranted to establish the correlation between psychiatric disorders and homicidal ideation among adolescents.

Bullying entre adolescentes brasileños: evidencias de las Encuestas Nacionales de Salud Escolar, Brasil, 2015 y 2019

Resumen Objetivo: estimar la prevalencia de indicadores relacionados con el bullying entre escolares brasileños de 13 a 17 años y comparar los eventos de 2015 y 2019. Método: estudio descriptivo, transversal, con datos de las Encuestas Nacionales de Salud Escolar realizado en todos los estados brasileños. Las prevalencias e intervalos de confianza (IC95%) de los indicadores se estimaron en 2019. Para probar las diferencias entre las dos ediciones se utilizó la prueba T de Student (p ≤ 0,01). Resultados: la prevalencia de la práctica de bullying disminuyó del 20,4% (IC95%: 19,2-21,5) en 2015 al 12,0% (IC95%: 11,6-12,5) en 2019. Los motivos aducidos para sufrir bullying fueron similares en las dos ediciones: apariencia del cuerpo y rostro y color de piel o raza. Las prevalencias entre los estados brasileños fueron similares, siendo que hubo mayores índices de padecer bullying en el estado de Tocantins, de situaciones de cyberbullying en los estados de Mato Grosso y Amapá, y de hacer bullying en Río de Janeiro. Conclusión: hubo una reducción a la mitad en la práctica de bullying, con un informe señalando que la relación no es buena entre los adolescentes brasileños, sin embargo, la prevalencia de bullying y cyberbullying es alta en el país. Por lo tanto, se debe prestar atención a las políticas públicas para reducir y enfrentar esta situación en el escenario nacional.

Bullying among Brazilian adolescents: evidence from the National Survey of School Health, Brazil, 2015 and 2019

Abstract Objective: to estimate the prevalence rate of indicators related to bullying among Brazilian students aged 13 to 17 years and compare its occurrence between 2015 and 2019. Method: this is a descriptive cross-sectional study, with data from the National Survey of School Health, carried out in all Brazilian states. The prevalence rate and confidence intervals (95%CI) of the indicators were estimated in 2019. Student’s t test was used (p ≤ 0.01) to test the differences between editions. Results: the prevalence rate of bullying decreased from 20.4% (95%CI: 19.2 - 21.5) in 2015 to 12.0% (95%CI: 11.6 - 12.5) in 2019. The reasons cited for being bullied were similar in both editions: bodily appearance, facial appearance, and color/race. Prevalence rates were similar between states. The state of Tocantins presented the highest number of bully-victims; states of Mato Grosso and Amapá had the highest number of adolescents being involved in cyberbullying situations, and the state of Rio de Janeiro presented the highest number of bullies. Conclusion: there was a reduction by half in bullying and in the report on not being treated well among Brazilian adolescents; however, the prevalence rate of being bullied and cyberbullying are high in the country. Therefore, attention should be paid to policies to reduce and confront this issue on the national scene.

Bullying entre adolescentes brasileiros: evidências das Pesquisas Nacionais de Saúde do Escolar, Brasil, 2015 e 2019

Resumo Objetivo: estimar a prevalência de indicadores referentes ao bullying entre escolares brasileiros de 13 a 17 anos e comparar sua ocorrência entre 2015 e 2019. Método: estudo descritivo, transversal, com dados das Pesquisas Nacionais de Saúde do Escolar, realizada em todos os estados brasileiros. Foram estimadas as prevalências e os intervalos de confiança (IC95%) dos indicadores em 2019. Para testar as diferenças entre as duas edições, utilizou-se o teste t de Student (p ≤ 0,01). Resultados: a prevalência de praticar bullying reduziu de 20,4% (IC95%: 19,2-21,5) em 2015 para 12,0% (IC95%: 11,6-12,5) em 2019. Os motivos apontados para sofrer bullying foram semelhantes nas duas edições: aparência do corpo, aparência do rosto e cor ou raça. As prevalências foram semelhantes entre os estados, sendo mais elevado sofrer bullying no Tocantins, envolver-se em situações de cyberbullying em Mato Grosso e Amapá, e praticar bullying foi mais elevado no Rio de Janeiro. Conclusão: ocorreu redução da prática do bullying pela metade, e do relato de não ser bem tratado entre adolescentes brasileiros, entretanto a prevalência de sofrer bullying é elevada no país, bem como o cyberbullying. Por isso, deve-se ter atenção e priorizar políticas para redução e enfrentamento desta prática no cenário nacional.
