What is the early adulthood outcome of boys who bully or are bullied in childhood? The Finnish "From a Boy to a Man" study

Meta-analysis of prospective longitudinal cohort studies on the impact of childhood traumas on anxiety disorders

OBJECTS

Childhood trauma is an early pathogenic factor that increases individuals' vulnerability to mental illness. This systematic review aims to explore the evidence regarding the association between childhood trauma and the subsequent occurrence of anxiety disorders.

METHODS

Embase, Scopus, and PubMed databases were searched for peer-reviewed longitudinal cohort studies published in English between January 1, 1995, and November 15, 2022. These studies investigated the association between childhood traumas and later diagnose of anxiety disorders. Including studies in one previous meta-analysis and two umbrella reviews, a total of 27 manuscripts were retained in this meta-analysis.

RESULTS

The evidence strongly revealed that childhood trauma exposure has detrimental effects on anxiety disorders, consistent from youth to adulthood. Moreover, these effects remained consistent across various types of anxiety disorders, including generalized anxiety disorder and social anxiety disorder, agoraphobia, specific phobia, panic attack and panic disorder. Importantly, exposure to childhood trauma, including maternal dysfunction, paternal dysfunction, physical abuse, sexual abuse, emotional abuse and bullying, was associated with later development of anxiety disorders, with bullying and maternal dysfunction ranking highest.

CONCLUSIONS

This meta-analysis underscores that childhood trauma exposure significantly increases the risk of anxiety disorders across different age groups and types of anxiety disorders. Various forms of childhood trauma, including maternal dysfunction, paternal dysfunction, physical abuse, sexual abuse, emotional abuse and bullying, are consistently associated with later development of anxiety disorders, highlighting the importance of early intervention and support in preventing anxiety disorders.

Childhood adversity and peer influence in adolescent bullying perpetration

Bullying among South African adolescents is a critical public health issue. This study explores the relationship between childhood adversity, peer influence, and personality traits in predicting bullying perpetration. Data from 769 high school learners were analysed using Structural Equation Modelling. Findings indicate that childhood adversity predicts bullying perpetration, mediated by peer influence and moderated by personality traits like conscientiousness, extraversion, and emotional stability. These results support Social Learning Theory, emphasising observed behaviours and peer dynamics in bullying. Practical implications include targeted interventions addressing childhood adversity and fostering positive peer interactions and personality development.

Relational Victimization, Characterological Self-Blame, and Adjustment in Young Children

The associations between relational victimization, self-blame attributions, and internalizing problems in early childhood has not previously been examined. Using a sample of 116 preschool children, average age 44.05 months (SD = 4.23), multiple informants, multiple methods, and a longitudinal design, path analyses were conducted to explore the associations between relational victimization, self-blame attributions (Characterological Self-Blame[CSB] and Behavioral Self-Blame[BSB]), and maladjustment in early childhood. Concurrent significant associations were found between relational victimization and internalizing problems. The initial longitudinal models revealed some significant effects that were consistent with predictions. Importantly, follow-up tests decomposing internalizing problems, indicated that anxiety at Time 1 was positively and significantly associated with CSB at Time 2. Depression at Time 1 was negatively and significantly associated with CSB at Time 2. Implications of this work are discussed.

Role of physical and dentofacial features in bullying among United Arab Emirates schoolchildren and its impact on school performance - A cross-sectional study

BACKGROUND

Bullying has a lasting effect on young, vulnerable minds, especially among school-aged youngsters. With the help of this study, we intended to examine how physical and dentofacial characteristics contribute to bullying among kids and how it affects their academic performance.

METHODS

This retrospective cross-sectional study consisted of a self-reported anonymous, pretested questionnaire divided into three major domains, with due institutional ethical clearance being obtained before the study's commencement.

RESULTS

The study population consisted of 269 schoolchildren, with 49.8% being males and the majority (55.0%) residing in Ajman. Among the schoolchildren, 35.7% reported being victims of bullying. The majority of bully victims (27.1%) skipped school because of bullying. Additionally, 64.3% of the students had a nickname, primarily used by siblings, and approximately half of the bully victims disliked their nicknames. In terms of happiness, 45.0% of students were neither happy nor unhappy in classes, while 10.8% were very unhappy. Outside of school, 56.9% of participants were very happy, and only 1.1% were very unhappy. Most students (58.7%) did not believe that bullying harms their grades, while 19.7% believed it does. Furthermore, 71.7% of students did not experience bullying due to good grades or showing interest in schoolwork.

CONCLUSION

Based on results, physical and dentofacial features in bullying among schoolchildren and its impact on school performance, sociodemographic patterns, and factors associated with bullying victimization highlight the need for targeted interventions and preventive strategies to address this issue. Thus, can create a safe and supportive school environment that promotes the well-being and academic success of all schoolchildren.

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.

Bullying of LGBTQ+ children and adolescents in schools: understanding the phenomenon, consequences, and international standards with a focus on the polish context

Bullying refers to repetitive, aggressive behavior intended to harm or intimidate others. Cyberbullying extends this aggression to digital platforms, involving harassment via social media, texts, or emails. These forms of bullying are particularly damaging to LGBTQ+ youth, who often face discrimination based on their sexual orientation or gender identity. In the context of LGBTQ+ individuals, bullying and cyberbullying can lead to severe emotional and psychological harm, contributing to higher rates of depression, anxiety, and suicidal ideation. Despite extensive global efforts and campaigns to combat homophobia, LGBTQ+ students continue to face significant challenges, with the situation in Poland being notably severe. The review highlights various forms of bullying, including physical, verbal, and social aggression, and underscores the alarming involvement of school personnel in perpetuating such behaviors. The focus on the Polish context enriches the global discourse on LGBTQ+ rights and highlights the critical need for targeted interventions to support vulnerable youth in regions with prevalent conservative and religious sentiments.

The Role of Disability in the Relationship Between Mental Health and Bullying: A Focused, Systematic Review of Longitudinal Studies

Having both a disability and being bullied increases the risk of later mental health issues. Children with disabilities are at greater risk of being bullied and therefore at greater risk of adverse mental health outcomes. We conducted a limited systematic review of longitudinal studies focusing on the role of disability in relation to bullying and mental health problems. Twelve studies with an initial measure of mental health or disorder, measured no later than 10 years of age, were found. Ten of these twelve studies suggested that having a disability before victimisation increased the impact of mental health problems measured after bullying experiences. The conclusion is that children with a disability, such as behavioural problems, have an increased risk of later mental health problems through bullying victimization. Children with two risk factors had significantly worse mental health outcomes. These additional mental health problems may be alleviated through reduced bullying victimisation.

Independent effects of early life adversity on social cognitive function in patients with schizophrenia

Objective

The aim of this study was to investigate the impact of early life adversity on cognitive function in patients with schizophrenia, with a focus on social cognition (SC).

Methods

Two groups of patients with schizophrenia were recruited and matched on sociodemographic and clinical characteristics. One group consisted of 32 patients with a history of childhood trauma (SCZ-ct), and the other group consisted of 30 patients without a history of childhood trauma (SCZ-nct). In addition, 39 healthy controls without a history of childhood trauma (HC-nct) were also recruited. The intelligence of the three groups was assessed using the Wechsler Abbreviated Scale of Intelligence (WAIS-RC) short version. The cognitive function evaluation was conducted using the MATRICS Consensus Cognitive Battery (MCCB), and early life adversity was measured using the Childhood Trauma Questionnaire-Short Form (CTQ) and Bullying Scale for Adults (BSA).

Results

Patients with schizophrenia endosed significantly higher scores on the CTQ (F=67.61, p<0.001) and BSA (F=9.84, p<0.001) compared to the HC-nct. Analysis of covariance (ANCOVA) and post-hoc analyses revealed that SCZ-ct (F=11.20, p<0.001) exhibited the most pronounced cognitive impairment among the three groups, as indicated in MCCB total scores and in the domain score of SC. CTQ exhibited a negative correlation with MCCB (r=-0.405, p< 0.001); SC was negatively correlated with physical abuse (PA) of CTQ (r=-0.271, p=0.030) and emotional abuse (EA) of BSA (r=-0.265, p=0.034) in the whole patient sample. Higher SC performance was significantly predicted by CT_total (Beta =-0.582, p<0.001, 95% CI -0.96-0.46), and years of education (Beta=0.260, p =0.014, 95% CI 0.20-1.75) in schizophrenia.

Conclusions

Besides familial trauma, schizophrenia patients appear to have a higher likelihood of experiencing bullying in their early life. These experiences seem to contribute significantly to their severe impairments in SC.

Consequences of high school bullying on stress and health of Arab American college students

PROBLEM

Existing bullying research among Arab Americans is limited, focusing mainly on school-age adolescents and victimization. There is a lack of studies that examine retrospective bullying perpetration, bullying victimization, and physical fights during high school and their effect on current Arab American college students' stress and health outcomes. This study examines if bullying perpetration, bullying victimization, and physical fights during high school predict current stress and the physical and mental health of Arab American college students. In addition, we examined if perceived psychological stress mediates the relationships between bullying and fighting involvement and health.

METHODS

One hundred and sixty-two undergraduate Arab American college students were recruited from a Midwestern university and completed self-report measures of bullying, stress, and health (both physical and mental).

FINDINGS

Controlling for demographic variables, only high school victimization was significantly associated with current stress and physical and mental health. Stress fully mediated the relationship between victimization and health (both physical and mental).

CONCLUSIONS

Victimization during high school years may result in serious physical and mental health consequences during college years. However, perpetration and fighting may not have similar effects. Addressing stress among bullying victims may reduce the negative impact of this experience on immigrant Arab American college students. Implications for practice and future research are discussed.

Peer Victimization Trajectory and Psychosocial Maladjustment in Early Taiwanese Adolescents: A Longitudinal Study

This study examined the peer victimization trajectory and maladjustment outcomes among early Taiwanese adolescents. Data were extracted from a large-scale longitudinal study with a national representative sample. A total of 1691 school students in 4th, 6th, and 8th grade were analyzed. Using latent profile analysis, students were classified into four trajectories, chronic victims, late onset victims, desisters, and non-victims, based on their self-reported physical and verbal victimization at three time points. Maladjustment, including psychological distress, reduced school attachment, internet addiction, and suicidal ideation in 8th grade, were assessed. The results showed significant differences in adjustment among students in the four trajectories. Chronic victims had the poorest outcomes on most variables, followed by late onset victims and desisters, while non-victims had the least maladjustment. The findings highlight the need for future interventions that would consider students' victim status over time and pay particular attention to those who suffer constant bullying and abuse.

Bullying at 8 years and violent offenses by 31 years: the Finnish nationwide 1981 birth cohort study

This study explored the associations between bullying perpetration and victimization at 8 years of age and violent offenses by the age of 31. Data were obtained for subjects enrolled in a population-based longitudinal birth cohort study. In 1989, 5813 8-year-old children (attrition 3.4%), and their parents and teachers, were surveyed about bullying. When 5405 subjects (attrition 10.2%) were 15-31 years of age, violent offenses were extracted from the Finnish National Police Register. We analyzed the data by sex and categorized bullying perpetration and victimization by frequency. Violent offenses were categorized by severity. Cox regression analyses estimated the hazard ratios (HRs) and 95% confidence intervals (95% CIs). When they were compared to males who had not been bullies at 8 years of age, frequent male bullies had an increased hazard for violent offenses (adjusted HR 3.01, 95% CI 2.11-4.33) and severe violent offenses (adjusted HR 2.86, 95% CI 1.07-7.59) as adults, even when the data were controlled for them being victims, parental education level, family structure and child psychopathology. Frequent female bullies also had an increased hazard for violent offenses, compared to those who had not bullied others (adjusted HR 5.27, 95% CI 1.51-18.40). Frequent male bullying was associated with higher odds for violent offenses compared to only bullying sometimes. Being a victim was not associated with violent offenses. Preventing childhood bullying could reduce violent offenses by both sexes.

Longitudinal relationships between school assets, traditional bullying, and internet gaming disorder: the role of self-control and intentional self-regulation among Chinese adolescents

Introduction

Although developmental assets have been proven to be enabling factors for both adolescent traditional bullying and internet gaming disorder (IGD), there is a lack of empirical evidence that has investigated the direct relationship between school assets and both of these problematic behaviors concurrently. Based on the positive youth development (PYD) perspective, the present study aimed to explore the relationship between school assets, intentional self-regulation (ISR), self-control, traditional bullying, and IGD among Chinese adolescents.

Methods

A total of 742 middle school students (M_age = 13.88 years, SD = 1.99 years) were followed up to measure school assets, ISR, self-control, traditional bullying, and IGD in two waves that were separated by 5 months.

Results

Structural equation modeling (SEM) indicated that T1 school assets negatively predicted T2 traditional bullying and T2 IGD. T1 self-control significantly mediated the relationships between T1 school assets and T2 traditional bullying, as well as between T1 school assets and T2 IGD. Additionally, T1 ISR strengthened the positive effect of T1 school assets on T1 self-control and further moderated the two mediating paths.

Discussion

These findings show that plentiful school assets support the development of self-control and are more successful in reducing traditional bullying and IGD, particularly among students with higher ISR. As a result, schools should take measures to provide superior-quality assets for the positive development of youth, which will help to prevent and relieve traditional bullying and IGD in the school context.

Depressive rumination and trait anxiety mediate the effects of childhood victimization on adulthood depressive symptoms in adult volunteers

BACKGROUND

Prior studies have reported that childhood victimization experiences substantially augment the risk of depression and suicide in adulthood. Several of our previous studies suggested that childhood experiences of victimization interact with the quality of parenting experienced in childhood, childhood experiences of abuse, neuroticism, and other factors to influence depressive symptoms in adulthood. In this study, it was hypothesized that "childhood victimization" worsens "trait anxiety" and "depressive rumination", and that "trait anxiety" and "depressive rumination" are mediators that worsen "depressive symptoms in adulthood".

SUBJECTS AND METHODS

The following self-administered questionnaires were completed by 576 adult volunteers: Patient Health Questionnaire-9, State-Trait Anxiety Inventory form Y, Ruminative Responses Scale, and Childhood Victimization Rating Scale. Statistical analyses were performed by Pearson correlation coefficient analysis, t-test, multiple regression analysis, path analysis, and covariance structure analysis.

RESULTS

Path analysis demonstrated that the direct effect was statistically significant for the paths from childhood victimization to trait anxiety, depressive rumination, and depressive symptom severity. Moreover, the indirect effect of childhood victimization on depressive rumination mediated by trait anxiety was statistically significant. The indirect effects of childhood victimization on depressive symptom severity mediated by trait anxiety and depressive rumination were statistically significant. Furthermore, the indirect effect of childhood victimization on depressive symptom severity mediated by both trait anxiety and depressive rumination was statistically significant.

CONCLUSIONS

We found that childhood victimization directly and adversely influenced each of the above factors, and indirectly worsened adulthood depressive symptoms with trait anxiety and depressive ruminations as mediating factors. The present study is the first to clarify these mediation effects. Therefore, the results of this study suggest the importance of preventing childhood victimization and the importance of identifying and addressing childhood victimization in patients with clinical depression.

Long-term consequences of bullying involvement in first grade

Few prospective studies have examined how early bullying experiences impact long-term adjustment and the differential impact of children's co-occurring bullying and peer victimization involvement on adjustment in adulthood. This study addressed these gaps by examining subgroups of first graders involved in bullying and associations with four outcomes in early adulthood, including (a) Major Depression diagnosis, (b) post-high school suicide attempt, (c) on-time high school graduation, and (d) criminal justice involvement. Additionally, middle school standardized reading test scores and suspensions were examined as potential mechanisms through which early bullying involvement is associated with adult outcomes. Participants were 594 children from nine urban elementary schools in the United States who participated in a randomized controlled trial of two school-based universal prevention interventions. Latent profile analyses using peer nominations identified three subgroups: (a) High involvement bully-victims, (b) Moderate involvement bully-victims, and (c) Low/No involvement youth. Compared to the No/Low involvement class, High involvement bully-victims were less likely to graduate high school on time (OR = 0.48, p = .002) and Moderate involvement bully-victims were more likely to be involved in the criminal justice system (OR = 1.37, p = .02). High bully-victims were at greater risk for both not graduating high school on-time and criminal justice system involvement, which were partially explained by 6th grade standardized reading test scores and suspensions. Moderate bully-victims were less likely to graduate high school on time, which was partially explained by 6th grade suspensions. Findings highlight how early bully-victim involvement increases risk for difficulties that affect adult quality of life.

The prevalence of peer bullying and psychiatric symptoms among high school students in southeast Turkey

PURPOSE

The purpose of this study is to examine the prevalence of bullying among high school students, its associated factors, and the effects of engaging in bullying behaviors on mental health.

MATERIALS AND METHODS

This cross-sectional study was conducted between 2021 and 2022 in the province with the highest population of children in the Southeast Anatolia region of Turkey. The data of the study were collected using the Sociodemographic Characteristics Questionnaire prepared by the researchers, Olweus Bully/Victim Questionnaire (OBVQ), and Depression Anxiety Stress Scale 42 (DASS-42).

RESULTS

Of the 880 students who participated in the study, 34.2% reported being a victim of bullying and 13.9% reported bullied someone. Regression analysis revealed that overweight/obesity was a risk factor for both victims and bullies. On the other hand, male gender and alcohol consumption were significantly associated with bullying. Scores for depression, anxiety, and stress were significantly higher in both the victim and the bullying groups compared to students who did not fall into this cycle.

CONCLUSIONS

The present findings suggest that bullying in school creates problems not only for the bullying victims but also for the bullies. Health professionals assessing youth should be aware of the characteristics of young people who may be involved in bullying.

Association between Child Abuse, Depression, and School Bullying among Chinese Secondary School Students

INTRODUCTION

School bullying is a serious social and public health problem. This article aims to explore the association between experiences of childhood abuse and involvement in school bullying, especially considering the mediating effects of depression.

METHODS

The sample of this study was 3059 students (1584 males and 1475 females) aged from 12 to 20, in eleven Chinese secondary schools, which included six middle schools, four high schools, and one vocational high school in both urban and rural areas. The multinomial logit regression and linear regression were conducted by the two gender groups, to determine the mediating effect of depression in the association between child abuse experiences and involvement in school bullying.

RESULTS

This study indicated that female students were less likely to be involved in school bullying. Male students were more represented in the bully-victim group and experienced more physical and mental abuse during childhood. Depression was a mediator between childhood abuse and involvement in school bullying. Nevertheless, there was a gender difference in that depression fully mediated the relationship between the two variables among female students, while it only partially meditated such a relationship for male students.

CONCLUSIONS

These findings indicate that more school-based service interventions and evidence-based research are needed to more thoroughly investigate school bullying and its predictors in China.

A revised and extended systematic review and meta-analysis of the relationship between childhood adversity and adult psychiatric disorder

This study aimed to systematically review the evidence for an association between adversity experienced in childhood (≤ 17 years old), and the diagnosis of psychiatric disorder in adulthood. Electronic databases (Scopus, Medline (for Ovid), EMBASE, and PsychINFO) were searched for peer-reviewed, longitudinal cohort studies examining child or adolescent exposure to adversity, and adult-diagnosed depression, anxiety, psychotic disorder, eating disorders, substance abuse disorder, illness anxiety disorder, somatoform disorder, or personality disorder. A total of 39 manuscripts were retained. Results revealed a significant association between the following childhood exposures and adult mental disorder (1.24 ≤ Odds ratios ≤ 2.09): bullying (victimhood, and frequency); emotional abuse; neglect; physical abuse; parental loss; and general maltreatment (unspecified and/or multiple adversity exposure). There were opposing results for being a victim and perpetrator of bullying, and the result for sexual abuse was not statistically significant. There was some evidence of a dose-response relationship with those exposed to multiple forms of maltreatment having more two and a half times odds of developing a mental disorder (Odds ratio = 2.59). The result for sexual abuse is likely an artefact of the prospective assessment of this adversity. In summary, there was strong evidence of an association between childhood adversity and later mental illness, and this supports previously reported meta-analyses. The evidence suggests that childhood and adolescence is an important time for risk for later mental illness, and an important period in which to focus intervention strategies for those known to have been exposed to adversity, particularly multiple adversities.

Below average motor skills predict victimization from childhood bullies: A study of adults with ADHD

Children with ADHD are frequently clumsy and involved in bullying, both as victims and perpetrators. The relationship between motor skills and bully status is poorly understood. The aim of the current study was to evaluate the effect of motor skills in childhood on bully victimization/perpetration in those with ADHD. In this cross-sectional study, 403 adults diagnosed with ADHD filled out a questionnaire on their recall of bully victimization, bully perpetration, performance in physical education (PE) (defined as performance below average in i.e., ball dexterity, coordination or agility) as a proxy for motor skills, and academic skills at age 12, as compared to their peers. Of the current sample, 63% remembered being victimized and 31% noted they were perpetrators. Thirty-two percent recalled that they performed below average in PE. Being diagnosed with ADHD and having poor motor skills was strongly associated with bully victimization (OR = 2.63; 95% CI:1.62, 4.27, p < .001). Victimization was more common during all measured time periods, from nursery school until the age of 15, among those with poor performance in PE as compared to those without poor performance. No relationship was found between poor motor skills and bully perpetration. CONCLUSION: A crucial role of the cerebellum is coordination and the linking of sequenced motor actions through milli-second timing. Aberrations in this ability makes a person present as "different", which was stated as the most common reason for social exclusion by other children. Therefore, subtle clumsiness (presumed by poor performance in PE class) is suggested to mirror deficits in social skills, which is intuitively observed by peers, leading to victimization.

Victimization by traditional bullying and cyberbullying and the combination of these among adolescents in 13 European and Asian countries

There has been a lack of studies on bullying in non-western low-income and middle-income countries. This study reported the prevalence of traditional victimization, cybervictimization, and the combination of these, in 13 European and Asian countries, and explored how psychiatric symptoms were associated with victimization. The data for this cross-sectional, school-based study of 21,688 adolescents aged 13-15 were collected from 2011 to 2017. The main outcomes were traditional and cybervictimization obtained from student self-reports. The Strengths and Difficulties Questionnaire was used to assess psychiatric symptoms. Generalized estimating equation and logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). The mean prevalence of any victimization was 28.9%, of traditional victimization only, this was 17.7%, and for cybervictimization only this was 5.1%. Cybervictimization occurred both independently, and in combination with, traditional victimization. The mean prevalence of combined victimization was 6.1%. The mean proportion of those who were cyberbullied only among those who were either cyberbullied only or bullied both traditionally and in cyber was 45.1%. The rates of prevalence varied widely between countries. In the total sample, those who experienced combined victimization, reported the highest internalizing symptoms (girls, OR 1.25, 95% CI 1.22-1.29; boys, OR 1.29, 95% CI 1.25-1.33). The study findings suggest that anti-bullying interventions should include mental health components and target both traditional and cyberbullying. Due to the overlap between these, targeting bullying should primarily focus on how to reduce bullying behavior rather than just focusing on where bullying takes place.

Household Dysfunction Is Associated With Bullying Behavior in 10-year-old Children: Do Socioeconomic Circumstances Matter?

This study measured the prevalence of bullying behavior in 10-year-old children and investigated the effect of the socioeconomic context on the impact of household dysfunction on bullying. We studied 5,338 members of the Portuguese Generation XXI birth cohort. Information on involvement in bullying, socioeconomic characteristics, and household dysfunction was collected by trained interviewers using structured questionnaires. Being a victim of bullying was reported by 14.4% of participants, being a bully by 1.4%, and being a bully-victim by 3.9%. Being a victim or both bully-victim, simultaneously, was more frequent among children from medium-high income families. Also, children from low-income families who reported household substance abuse, witnessed parents' intimate partner violence, and were victims of physical violence, were more frequently victims of bullying; and those who experienced family violence were more frequently involved as bully-victims. Among children from medium-high income families, all these household adversity experiences significantly increased the odds of being victim, bully, or bully-victim. Thus, although children from medium-high income families are less likely to experience adversity at home, when it happens, there is a greater effect on their behavior, suggesting that better socioeconomic circumstances do not seem to act as a protective factor.

Associations between school bullying and anxiety in children and adolescents from an ethnic autonomous county in China

School bullying is a widespread public health issue that negatively impacts the mental health of children and adolescents. This study aimed to investigate associations between school bullying involvement and anxiety of children and adolescents. A survey covering all types of pre-college schools (primary, middle, high, and vocational school) was conducted in an ethnic autonomous county in China. 1,943 students participated in this study. Being a victim of verbal (OR=3.08, 95%CI = [2.43,3.91]), physical (OR=3.24, 95%CI = [2.46,4.27]), relational (OR=3.72, 95%CI = [2.90,4.76]), or cyberbullying (OR=3.47, 95%CI = [2.61,4.61]) were associated with increased symptoms of generalized anxiety. Similarly, being a perpetrator of verbal (OR=2.12, 95%CI = [1.45,3.10]), physical (OR=1.85, 95%CI = [1.22,2.79]), relational (OR=1.78, 95%CI = [1.15,2.74]), or cyber-bullying (OR=1.59, 95%CI = [1.08,2.33]) were related to a higher degree of anxiety. Moreover, in both victims and perpetrators higher levels of anxiety were associated with a greater number of types of bullying they were involved in, suggesting a dose-response relation between school bullying involvement and anxiety. Therefore, both bullying victims and perpetrators need mental health support and anti-bullying strategies should address different forms of bullying evenhandedly.

School assets and bullying in Chinese youth: A multiple mediation model of intentional self-regulation and internet gaming disorder

Bullying is a severe social problem affecting young people all over the world. Previous studies suggested that engagement in bullying had massive effects on teenagers' physical and psychological development. It is critical and necessary to investigate the antecedents and underlying mechanisms of this phenomenon among young generations. The present study, based on the positive youth development perspective and the developmental assets theory, attempts to explore the positive factors in the school subsystem that could effectively prevent adolescents from bullying, as well as the multiple mediation effects of intentional self-regulation (ISR) and internet gaming disorder (IGD). In this study, we adopted a two-wave design and recruited a sample of 768 Chinese adolescents using a randomized cluster sampling method in the post-pandemic era. The results revealed that T1 school assets significantly and negatively predicted T2 adolescent bullying. Furthermore, T2 ISR and T2 IGD mediated the association between T1 school assets and T2 bullying separately and sequentially. Overall, school resources play a protective role in adolescent development and could effectively prevent them from negative outcomes. These current findings contribute to the literature by providing a further understanding of the direct and indirect protective effects of school assets on adolescent bullying. Moreover, practitioners could also benefit from these findings in preventing and intervening in bullying in the school subsystem.

Substance use confounds associations between peer victimization and aggression in adolescence with mental disorders in adulthood: A prospective birth cohort study

INTRODUCTION

Peer victimization and aggression in adolescence are associated with later mental health morbidity. However, studies examining this association have not controlled for adolescent substance use. We aimed to study the associations between peer victimization, peer aggression, and mental disorders in adulthood, adjusting for substance use in adolescence.

METHODS

Participants were from the prospective Northern Finland Birth Cohort 1986. Data were available for 6682 individuals (70.8% of the original sample). Peer victimization and peer aggression were assessed with items from the Achenbach Youth Self Report at ages 15-16 years. Outcomes were nonorganic psychosis, anxiety disorder, mood disorder, substance use disorder, and any mental disorder (a none-vs-any indicator) at age 33 years collected from nationwide health care, insurance, and pension registers. Family structure, alcohol intoxication frequency, daily smoking, illicit drug use, and baseline psychopathology using Youth Self-Report total score, and parental mental disorders were considered as confounding factors.

RESULTS

In multivariable analyses, the association between peer victimization and psychosis (Hazard ratio [HR]: 2.9, 95% confidence interval [CI]: 1.2-6.9, p = .020) and mood disorder (HR: 1.7, 95% CI: 1.2-2.4, p = .012) in females remained significant after adjusting for confounders. Other associations between female and male peer victimization or aggression and the studied outcomes attenuated after adjustments.

CONCLUSIONS

Some associations between peer victimization and aggression and later mental health morbidity are explained by adolescent substance use. For females, substance use does not account for the increased risk of psychosis and mood disorder in those who experience peer victimization.

External Locus of Control but not Self-Esteem Predicts Increasing Social Anxiety Among Bullied Children

Background

Elevated social anxiety is more likely among bullied children than those who have not been bullied but it is not inevitable and may be influenced by cognitive factors. Lower self-esteem and more external locus of control are associated with bullying and social anxiety but the impact of these factors over time among bullied children is less clear.

Method

Children from the UK Avon Longitudinal Study of Parents and Children (ALSPAC) reported bullying experiences at age 8 (n = 6,704) and were categorized according to level of bullying exposure. The impact of self-esteem and locus of control on social anxiety was assessed up to age 13 across the bullying exposure groups using multi-group latent growth curve analysis. Complete data was available for 3,333 participants.

Results

More external locus of control was associated with a steeper increase in social anxiety among severely bullied children [B = .249, p = .025]. Although self-esteem at age 8 was associated with existing social anxiety it did not predict later increases in social anxiety.

Conclusion

These results indicate that beliefs about lack of personal control among severely bullied children may contribute to increasing social anxiety over time. Exploring related cognitions may be helpful in this potentially vulnerable group.

Effects of a Social and Emotional Competence Enhancement Program for Adolescents Who Bully: A Quasi-Experimental Design

BACKGROUND

The purpose of this study was to develop a social and emotional competence enhancement (SECE) program as an intervention for adolescents who bully, and to investigate its effects on school bullying behavior and mental health.

METHODS

A pre-posttest, 1-month follow-up nonequivalent control group quasi-experimental design was used. In total, 71 school bullies were included in the analysis.

RESULTS

The effects of this program were significant with regard to group-by-time interaction effects on social competence, emotional regulation, empathy, and school bullying behavior at the 1-month follow-up.

CONCLUSIONS

The results indicate that the SECE program was effective at reducing school bullying behavior in adolescents who bully. School and community-based mental health professionals can provide feasible interventions that can be used in the short term to reduce school bullying behavior in adolescents who bully.

Under the skin: does psychiatric outcome of bullying victimization in school persist over time? A prospective intervention study

BACKGROUND

Research has shown a direct path between peer victimization and poor mental health outcomes. However, the impact of bullying prevention on mental health is a largely unexplored field. Therefore, our study examined the longitudinal association between bullying development and trajectories of psychiatric symptoms (emotional problems, total difficulties, nonsuicidal self-injury, and suicidality) and health-related quality of life (HRQL) during the implementation of school-based bullying prevention.

METHODS

Data of 4,873 pupils (grades 5-13) were collected in 23 schools implementing the Olweus Bullying Prevention Program (OBPP). Self-report questionnaires were administered at three annual assessment waves and individual codes enabled the association of repeated assessments to the same pupil. Latent growth curve models (LGCMs) were used to examine the relation among bullying status and mental health outcome with mixed-effects linear regressions estimating the association of changes in bullying with changes in continuous scores and mixed-effects logistic regressions for categorical variables.

RESULTS

Latent growth curve models revealed an improvement of mental health and HRQL through the termination of bullying for every outcome variable of interest (all p < .001). Correspondingly, we found an explicit increase in psychopathology as well as decrease in HRQL within one year as a result of developing victimization (all p < .001). Interestingly, the growth of psychopathology associated with the onset of bullying was significantly steeper than its decline associated with the termination of bullying. The postulated cumulative effect of ongoing bullying for a further year could only be shown for HRQL (p = .025) and total difficulties (p = .034), but not for specific mental health problems (all p > .117).

CONCLUSIONS

Latent growth curve models clearly showed that the adverse psychosocial consequences of bullying arise quickly but seem to reduce much slower and partly persist over time. Future long-term studies are necessary to clarify if mental health problems will return to baseline after several years or if residual symptoms will remain.

The association between the social environment of childhood and adolescence and depression in young adulthood - A prospective cohort study

BACKGROUND

Good social relationships with parents and peers protect children and adolescents from developing mental disorders in adulthood while several negative experiences increase the risk of depression in later life.

METHODS

We used population-based cohort data from the Northern Finland Birth Cohort (NFBC) 1986. Participants (n = 6147), their teachers and parents reported factors associated with the social environment of children and adolescents. Diagnoses of depression of cohort members were derived from Finnish nationwide registers. We conducted regression analyses to assess which factors of the social environment of childhood and adolescence were associated with depression in young adulthood.

RESULTS

Bullying victimization in adolescence was the strongest predictor of depression in young adulthood among girls (OR 2.23: 95% CI 1.47-3.39) and boys (OR 2.44: 95% CI 1.49-4.00). Loneliness and bullying behavior in childhood were associated with depression in boys only. Loneliness in adolescence (OR 1.63: 95% CI 1.30-2.04) was associated with depression among both genders. Spending with the family seemed to protect against the negative impact of bullying and loneliness.

LIMITATIONS

We used single-item study questions to measure social relationships. These questions do not necessarily describe the phenomena as accurately as the measures validated for them.

CONCLUSION

Problems in social relationships with peers in childhood and adolescence are associated with depression in young adulthood. Time spent with the family is emphasized in situations in which adolescents have problems in peer-relationships.

Does Anxiety Symptomatology Affect Bullying Behavior in Children and Adolescents with ADHD?

Background

Anxiety disorders are common comorbidities in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) who are also at a high risk of bullying behavior. However, little is known about the roles of anxiety symptomatology in the relationship between ADHD and bullying behavior.

Objective

This cross-sectional, clinic-based study aims to investigate the associations between anxiety symptomatology and bullying involvement in youth with ADHD.

Method

One hundred and eighty children and adolescents with ADHD aged 10–18 years participated in the study. The Screen for Child Anxiety-Related Emotional Disorders (SCARED) was self-rated, and the participants were interviewed with the Revised Olweus Bully/Victim Questionnaire to categorize bullying involvement. Data were analyzed through percentage, nonparametric statistics, chi-squared statistics, and logistic regression analysis.

Results

Sixty-nine percent of youth with ADHD reported involvement in bullying, of which 33.3%, 8.9%, and 27.2% were classified as victims, bullies, and bully-victims, respectively. The means and 95% confidence intervals of the total SCARED scores showed a significant difference among bullying behavior groups. The highest SCARED scores could be noticed in the victim and bully-victim groups, with the lowest scores observed in the bully group. Youth with ADHD who had comorbid anxiety were 3.51 times more likely to be bullied than those who did not have anxiety.

Conclusions

A differential effect of anxiety symptomatology on bullying behavior in youth with ADHD was evident. These results highlight the utility of including anxiety in the conceptualization of bullying problems in youth with ADHD to plan successful anti-bullying interventions.

Risk factors of school bullying and its relationship with psychiatric comorbidities: a literature review

Background

School bullying is described as violence to other people. It is perpetrated at schools or other activities when the power of a student or a group of students is used to injure others or other groups.

Main body

The prevalence of school bullying is varied from one country to another. There are many types of bullying, such as physical, verbal, social relations, psychological, sexual, and cyber-bullying. Many risk factors could affect school bullying, especially individual, peer and parent factors. Researches found that adults who had school bullying are more vulnerable to develop future psychiatric disorders.

Conclusions

School bullying is one of the crucial problems among pupils. The wide range of the prevalence of school bullying may be due to different methodologies and the presence of many risk factors. It is recommended to have long-term researches about the student with bullying behavior. Also, prevention programs are required to increase knowledge and early detection of affected students to prevent future psychiatric disorders.

Childhood Victimization and Neuroticism Mediate the Effects of Childhood Abuse on Adulthood Depressive Symptoms in Volunteers

BACKGROUND

When assessing patients with depressive and anxiety disorders in psychiatric clinical practice, it is common to encounter children and adolescents who have experienced abuse and victimization. To date, it has been clarified that experiences of "childhood abuse" and "childhood victimization" lead to "neuroticism", and that neuroticism leads to "adult depressive symptoms". In this study, we analyzed how these four factors are interrelated.

SUBJECTS AND METHODS

The following self-administered questionnaire surveys were conducted in 576 adult volunteers: Patient Health Questionnaire-9, Eysenck Personality Questionnaire-revised shortened version, Child Abuse and Trauma Scale, and Childhood Victimization Rating Scale. For statistical analysis, Pearson correlation coefficient analysis, t-test, multiple regression analysis, and covariance structure analysis (path analysis) were performed.

RESULTS

Path analysis showed that the indirect effects of childhood abuse and childhood victimization on depressive symptoms through neuroticism were statistically significant. In addition, the indirect effects of childhood abuse on neuroticism through childhood victimization were statistically significant. Finally, the indirect effects of childhood abuse on depressive symptoms through the combined paths of childhood victimization and neuroticism were statistically significant.

CONCLUSION

Our results suggest that "childhood abuse (A)" induces changes in the personality trait of "neuroticism (C)" with "childhood victimization (B)" as a mediator, and that these adversities affect the expression of "depressive symptoms in adulthood (D)" through "neuroticism (C)" as a mediator. In other words, to our knowledge, this is the first study to clarify that these four factors are not only individually associated with each other but also cause a chain reaction of A to B to C to D.

Relationship between Bullying Victimization and Quality of Life in Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) in Taiwan: Mediation of the Effects of Emotional Problems and ADHD and Oppositional Defiant Symptoms

This cross-sectional study investigated the mediating effects of emotional problems including depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD) symptoms on the association between bullying victimization and quality of life (QoL) among adolescents with ADHD in Taiwan. A total of 171 adolescents diagnosed as having ADHD participated in this study. Adolescents completed the School Bullying Experience Questionnaire, the Taiwanese Quality of Life Questionnaire for Adolescents, the Taiwanese version of the Children’s Depression Inventory and the Multidimensional Anxiety Scale for Children. Caregivers completed the Chinese version of the Swanson, Nolan, and Pelham Version IV Scale. Structural equation modeling (SEM) was used to examine the relationships among the variables. The results of SEM revealed that bullying victimization indirectly correlated with QoL through the mediation of emotional problems in adolescents with ADHD, whereas ADHD and ODD symptoms did not mediate the association between bullying victimization and QoL. Bullying victimization should be actively prevented and intervened on to ensure better QoL in adolescents with ADHD. Moreover, emotional problems should be alleviated among adolescents with ADHD with bullying victimization experience to maintain their QoL.

Contributions of childhood peer victimization and/or maltreatment to young adult anxiety, depression, and suicidality: a cross-sectional study

BACKGROUND

Childhood maltreatment and peer victimization are major risk factors for depression and suicidal behavior. Furthermore, childhood maltreatment increases the risk of peer victimization. Our objective was to distinguish between the contributions of parental maltreatment and peer victimization to the development of mental health problems in young adulthood. Specifically, we tested whether peer victimization alone or in combination with parental maltreatment before 18 years old was associated with anxiety, depression, and suicidal thoughts and behaviors at age 21 years.

METHODS

We analyzed data collected from questionnaires administered in the i-Share (Internet-based Students' Health ResearchEnterprise) study in France from February 2013 to September 2019 (N = 2271 participants). We performed multinomial and binary logistic regression analyses to assess the single and combined contributions of childhood peer victimization and parental maltreatment to anxiety, depression, and suicidality in adulthood.

RESULTS

Nearly one third of students (28.8%) reported at least one mental health problem; 29.8% reported peer victimization alone; 7.5% reported parental maltreatment alone; and 10.3% reported both parental maltreatment and victimization. In multivariate models, compared to participants that did not experience maltreatment or peer victimization, those that experienced peer victimization alone were more likely to report anxiety (adjusted odds ratio [aOR]: 1.90; 95% CI: 1.50-2.40), depression (aOR: 1.95; 95% CI: 1.46-2.60), or suicidal ideation, without (aOR: 1.62; 95% CI: 1.26-2.09) or with a suicide attempt (aOR: 2.70; 95% CI: 1.51-4.85). Similar associations were observed for participants that experienced maltreatment alone. Participants that experienced both maltreatment and peer victimization were at increased risk of depression (aOR: 2.63; 95% CI: 1.79-3.86) and suicidal ideation, with (aOR: 9.19; 95% CI: 4.98-16.92) and without a suicide attempt (aOR: 2.64; 95% CI: 1.86-3.76).

CONCLUSIONS

Separate and combined exposures to parental maltreatment and peer victimization in childhood or adolescence were associated with increased risks of anxiety, depression, and suicidal behaviors. Peer victimization appeared to play a specific role in mental health disorders that were not otherwise explained by polyvictimization. Currently, peer victimization is a frequent, but avoidable type of child abuse; therefore, these findings have implications for policies for preventing and dealing with peer victimization.

Bullying and Its Associated Individual, Peer, Family and School Factors: Evidence from Malaysian National Secondary School Students

Adolescents involved in bullying can be at risk of developing behavioural problems, physical health problems and suicidal ideation. In view of this, a quantitative research design using a cross-sectional study was conducted to determine the prevalence of bullying and associated individual, peer, family and school factors. The study involved 4469 Malaysian public-school students who made up the response rate of 89.4%. The students were selected using a randomized multilevel sampling method. The study found that 79.1% of student respondents were involved in bullying as perpetrators (14.4%), victims (16.3%), or bully-victims (48.4%). In a multivariate analysis, the individual domain showed a significant association between students' bullying involvement and age (OR = 1.38; 95% CI 1.12-1.70), gender (OR = 1.73; 95% CI 1.47-0.91), ethnicity (OR = 0.66; 95% CI 0.47-0.91), duration of time spent on social media during the weekends (OR = 1.43; 95% CI 1.09-1.87) and psychological distress level (OR = 2.55; 95% CI 1.94-3.34). In the peer domain, the significantly associated factors were the number of peers (OR = 0.69; 95% CI 0.56-0.86) and frequency of quarrels or fights with peers (OR = 2.12; 95% CI 1.24-3.26). Among the items in the school domain, the significantly associated factors were students being mischievous in classrooms (OR = 1.52; 95% CI 1.06-2.06), student's affection towards their teachers (OR = 1.53; 95% CI 1.06-2.20), frequency of appraisal from teachers (OR = 1.49; 95% CI 1.16-1.94), frequency of friends being helpful in classrooms (OR = 1.92; 95% CI 1.09-3.38) and frequency of deliberately skipping class (OR = 2.91; 95% CI 2.90-1.72). As a conclusion, the study revealed high levels and widespread bullying involvement among students in Malaysia. As such, timely bullying preventions and interventions are essential, especially in terms of enhancing their mental health capacity, which substantially influences the reduction in the prevalence rates of bullying involvement among students in Malaysia.

Bullying Victimization Among Peruvian Children: The Predictive Role of Parental Maltreatment

Bullying among schoolchildren is increasingly being recognized as a major problem. Although previous studies have examined parental maltreatment as a risk factor for bullying, the evidence on this topic remains limited in Latin America. The aim of this study was then to measure the prevalence of bullying victimization among a nationally representative sample of Peruvian children and to test the association between bullying victimization and parental maltreatment in Peru. This study used a pooled data set from the 2013 and 2015 Peru National Surveys on social relations. Participants were Peruvian children aged from 9 years to 11 years in the fourth, fifth, and sixth grade of primary in both public and private schools nationwide. The results indicated that almost one third of Peruvian children have experienced physical bullying and nearly half of them psychological bullying. However, only a small percentage reported experiencing bullying very frequently. Furthermore, it was found that parental maltreatment in any form-physical or psychological-was strongly and positively associated with physical and psychological bullying victimization. The results also showed that the probabilities of being physically or psychologically bullied were higher among children who experienced physical or psychological parental maltreatment than among children who have not experienced such violence. The probabilities of being bullied were even higher among children who experienced both types of parental maltreatment. Consistent with previous research, these findings suggest that the relationship that children establish with their parents will largely determine how they interact with their peers.

Role of involvement in bullying as predictor for hospital-treated assault exposures among former adolescent psychiatric inpatients

OBJECTIVE

Bullying is a common problem among children and adolescents. Previous studies have investigated the associations between involvement in bullying and various psychosocial and mental health outcomes thoroughly. However, only few studies have focused on the association between bullying and exposure to assaults. This study investigated whether the likelihood for severe assault exposure varies among three subgroups of bullying behavior: bullies/bully-victims, victims of bullying, and those not involved in bullying.

METHOD

The study population consisted of 508 adolescents (208 boys, 300 girls) aged between 13 and 17 years (mean age 15.5 years), admitted for psychiatric inpatient treatment between the years 2001-2006. Adolescents were interviewed at index hospitalization using semi-structured interview, K-SADS-PL, to assess DSM-IV based adolescent psychiatric disorders, and to obtain information on bullying behavior. Treatment episodes for assault incidents were obtained from the Finnish National Care Register for Health Care covering the entire-life of the study participants up to end of year 2016.

RESULTS

14.4% (n = 73) of the study participants had experienced severe physical or sexual assault leading to hospital treatment during their lifetime. Results of Cox regression analysis showed that girl bullies/bully-victims had nearly threefold increased likelihood for later assault exposure.

CONCLUSIONS

Since bullying behavior in childhood and adolescence is a significant predictor for later exposure to severe assault in girls, it should be paid attention to and intervened as early as possible. Moreover, psychosocial risk factors should be taken into account considering those in hospital treatment for severe assault exposure.

Childhood trauma and adult mental disorder: A systematic review and meta-analysis of longitudinal cohort studies

OBJECTIVE

To systematically review evidence for the association between trauma experienced in childhood or adolescence, and the subsequent experience of affective or psychotic mental disorders in adulthood.

METHODS

Electronic databases (Scopus, Medline (for Ovid), EMBASE and PsychINFO) were searched for peer-reviewed, longitudinal cohort studies in the English language examining child or adolescent exposure to trauma, and adult-diagnosed depression, anxiety, psychotic disorder or bipolar disorder. A total of 23 manuscripts were retained.

RESULTS

Results revealed a significant association between the following childhood exposures and adult mental disorder: bullying (victimhood, perpetration and frequency); emotional abuse; physical neglect; parental loss; and general maltreatment (unspecified and/or multiple trauma exposure). There was some evidence of a dose-response relationship with those exposed to multiple forms of maltreatment having more than three times the odds of developing a mental disorder (Odds ratio = 3.11, 95% CI = 1.36-7.14). There was no significant association found between physical or sexual abuse and adult mental disorder; however, this is likely an artefact of how these adversities were assessed.

CONCLUSION

There is strong evidence of an association between childhood trauma and later mental illness. This association is particularly evident for exposure to bullying, emotional abuse, maltreatment and parental loss. The evidence suggests that childhood and adolescence are an important time for risk for later mental illness, and an important period in which to focus intervention strategies.

Diagnostic and Therapeutic Challenges of Catatonia in an Adolescent With High Functioning Autism Spectrum Disorder: A Case Report

Catatonia is a psychomotor syndrome with specific clusters of speech, behavioral and motor features. Although potentially life-threatening, especially in its malignant form accompanied with autonomic dysregulation and medical complications, it is a treatable condition, when promptly identified. For a long time catatonia was considered a marker of schizophrenia, thus limiting the possibility of diagnosis and treatment. Due to growing awareness and studies on the subject, it is now known that catatonia can occur in the context of a number of diseases, including psychotic, affective and neurodevelopmental disorders. In recent years, there's been a renewed interest in the recognition and definition of catatonia in neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD), where the differential diagnosis poses great challenges, given the considerable overlapping of signs and symptoms between the conditions. We present the case of a 15 year old boy with High Functioning ASD with a sudden onset of severe catatonic symptoms and the co-existence of psychotic symptoms, whose complex clinical course raises many questions on the differentiation and relation of said disorders.

Ten-year changes in the psychosocial well-being, psychopathology, substance use, suicidality, bullying, and sense of coherence of 18-year-old males: a Finnish population-based time-trend study

We studied Finnish 18-year-old males attending obligatory military call-up assessments in 1999 (n = 2340) and 2009 (n = 4309) on time-trend changes in psychosocial well-being, psychopathology, substance use, suicidality, bullying, and sense of coherence. Subjects filled in questionnaires, including the Young Adult Self-Report (YASR) for psychopathology and the Orientation to Life Questionnaire (SOC-13) for sense of coherence. The prevalence of minor mental health problems in the last 6 months decreased from 22.3% in 1999 to 18.6% in 2009 (OR 0.8, 95% CI 0.7-0.9), whereas severe mental health problems remained stable. Suicidal thoughts decreased from 5.7 to 3.7% (OR 0.6, 95% CI 0.5-0.8). The use of illicit drugs decreased from 6.0 to 4.7% (OR 0.8, 95% CI 0.6-0.95), but being drunk at least once a week increased from 10.3 to 13.4% (OR 1.3, 95% CI 1.0-1.5). Attention problems increased in YASR syndrome domains (mean score 2.9 vs 3.2, p < 0.001) and so did somatic complains (mean score 1.7 vs 1.9, p = 0.005). The SOC-13 scores remained stable. The percentage of males who had studied during the past 6 months increased from 91.4 to 93.4% (OR 1.3, 95% CI 1.1-1.6), while being employed decreased from 64.9 to 49.4% (OR 0.5, 95% CI 0.5-0.6). The positive findings included reductions in the prevalence of suicidal thoughts and the use of illicit drugs, but being drunk at least once a week increased. Self-reported somatic problems and attention problems increased. Despite changes in society and family structures, there were only minor overall changes in psychopathology.

Health and behavioural outcomes of bullying victimisation among Indonesian adolescent students: findings from the 2015 Global School-based Student Health Survey

Bullying victimisation among adolescents is globally recognised as an important predictor for several adverse health and behavioural outcomes. Due to a paucity of studies in Indonesia, this study aimed to identify the adverse health and behavioural outcomes due to bullying victimisation among school-going adolescents and investigate the possible moderation by age and sex. This was an analysis of the second Global School-based Student Health Survey data of Indonesia conducted in 2015. The eligible samples were 9,601 adolescent students. The main independent variable was bullying victimisation status, while the dependent variables consisted of mental health problems, substance use, and other risk behaviours. Binary logistic regression controlling for some confounders was applied to identify the associations among sex-merged and sex-separated samples. Furthermore, adjusted margin probabilities of having adverse outcomes were calculated by bullying victimisation frequency and age. This study found that nearly 2 out of 10 adolescent students were bullied in the last 30 days. Bullying victimisation was associated with the odds of all adverse health and behavioural outcomes that include loneliness, anxiety, suicidal ideation, smoking cigarettes, alcohol use, truancy, physical fight, and sedentary behaviour. The associations were slightly larger among female than male students for some of the outcomes. The odds of these adverse outcomes increased with the rising frequency of bullying and by age. The findings suggest that bullying victimisation was associated with a number of adverse health and behavioural outcomes among Indonesian adolescent students. Implementation of anti-bullying interventions among students right from a young age is essential to prevent unexpected adverse outcomes and its detrimental consequences.

Bullying victimization and adverse health behaviors among school-going adolescents in South Asia: Findings from the global school-based student health survey

BACKGROUND

Bullying among adolescents is a global public health issue and has adverse behavioral and mental health consequences, yet a little is known about the relationship between bullying victimization and adverse health behaviors in adolescence in South Asian countries.

METHODS

Data for this cross-sectional analysis were extracted from the global school-based student health survey (GSHS) in Bangladesh (n = 2,989), 2014 and in Nepal (n = 6,529), 2015. Multivariate logistic regression analyses were used to identify the associations between bullying victimization and adverse health behaviors or outcomes: physical violence, sexual history, tobacco use, alcohol use, drug use, suicide ideation, plan, attempt, loneliness, and sleeping difficulty.

RESULTS

The prevalence of bullying victimization that occurred for a minimum of 1 day during the 30 days preceding the survey was 24.5% in Bangladesh and 50.9% in Nepal. This study observed significant relationships between bullying victimization and several adverse health behaviors/outcomes. For example, in Bangladesh, the odds of attempted suicide were found to be higher in adolescents that experienced bullying for 1-2 (adjusted odds ratio [AOR]: 2.92; 95% confidence interval [CI]: 1.64-5.19), 3-5 (AOR: 3.55; 95% CI: 1.69), 6-9 (AOR: 5.33; 95% CI: 1.24-22.77), or 10 days or more (AOR: 9.83; 95% CI: 4.17-23.16) during the 30 days preceding the survey than who did not.

CONCLUSIONS

Bullying among adolescents in school is common in Bangladesh and Nepal and is associated with several adverse health behaviors. Bullying and its potential health consequences are needed to be addressed in health promotion and programs in these countries.

Association of Childhood Intrafamilial Aggression and Childhood Peer Bullying With Adult Depressive Symptoms in China

IMPORTANCE

Childhood intrafamilial aggression, a series of aggressive behaviors inflicted by family members, and adulthood mental health are associated with childhood peer bullying (eg, in the neighborhood or in school). However, few studies have been able to identify the contribution of childhood peer bullying to the association between childhood intrafamilial aggression and adult depression.

OBJECTIVE

To examine the mediating role of childhood peer bullying in the association between childhood intrafamilial aggression and depression in adulthood.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cross-sectional study used data from the China Health and Retirement Longitudinal Study (CHARLS). Middle-aged and older adults (≥45 years) participated in a CHARLS wave from July 1 to September 30, 2015, and the CHARLS life history survey from June 1 to December 31, 2014, with complete data. A 4-step mediation model with logistic regression was run to test the mediating role of peer bullying. Data analysis was performed from October 1 to 30, 2019.

EXPOSURES

Childhood intrafamilial aggression, including parental physical maltreatment and sibling aggression, and peer bullying.

MAIN OUTCOMES AND MEASURES

Depressive symptoms measured by a categorical variable derived from the Center for Epidemiologic Studies Depression Scale, based on a cutoff score of 12.

RESULTS

Among the 15 450 respondents (mean [SD] age, 59.5 [9.9] years; 7987 women [51.7%]), 4422 (28.6%) were exposed to parental physical maltreatment; 986 (6.4%), to sibling aggression; and 2504 (16.2%), to peer bullying in childhood. Respondents experiencing intrafamilial aggression were more likely to be bullied by peers (parental physical maltreatment odds ratio [OR], 2.53 [95% CI, 2.25-2.83]; sibling aggression OR, 3.05 [95% CI, 2.46-3.78]). Children with these adverse experiences were at a higher risk of adult depression symptoms (parental physical maltreatment OR, 1.28 [95% CI, 1.15-1.42]; sibling aggression OR, 1.40 [95% CI, 1.13-1.74]; peer bullying OR, 1.78 [95% CI, 1.56-2.01]). Peer bullying mediated 30% (95% CI, 19%-42%) of the association between childhood parental maltreatment and adult depression and 35% (95% CI, 15%-54%) of the association between sibling aggression and depression symptoms in adulthood.

CONCLUSIONS AND RELEVANCE

This study found that being bullied by peers was a mediator of the association between childhood intrafamilial aggression and depression in adulthood. The findings have important implications to mitigate the effect of early-life stress and promote life-course mental health through dealing with childhood intrafamilial aggression and peer bullying experiences coordinately.

Peer victimisation and depression among gender conforming and non-conforming Thai adolescents

Like most low- and middle-income countries, Thailand is facing an increasing burden of depressive disorders among adolescents, but research and services for them are largely neglected. This study explored the association between types of peer victimisation, gender non-conformity, health risk behaviours, and depressive symptoms among Thai students aged 13-18 years. Overall, prevalence of depressive symptoms was 14.7% (95% CI: 12.6-15.6), 12.2% (95% CI: 9.5-13.9) among male students and 16.5% (95% CI: 13.8-18.0) among female students. Among both sexes, social and sexual victimisation in the past month were strongly associated with depressive symptoms in the past week. Gender non-conforming female adolescents, as well as male and female adolescents who had experienced sexual and social victimisation, had a high burden of depressive symptoms. Mental health professionals and educators working with young people in Thailand should consider assessment for clinically significant depressive disorders.

Can words be worse than stones? Understanding distressing social events and their relationship with social anxiety

Research on the relationship between distressing social events and social anxiety has focused on antagonistic social events (i.e., peer victimization, cyberbullying) in adolescent samples. There is little research examining such relationships in adults, and less examining the relationship between non-antagonistic distressing social events (i.e., accidental embarrassing events) and social anxiety. The current investigation utilized a retrospective design to examine how different distressing social events may be associated with posttraumatic stress-like reactions, which may relate to social anxiety in early adulthood. Characteristics of distressing social events (i.e., betrayal, presence of an antagonist) were explored as possible influences on the severity of stress responses. Community participants (n = 271; ages 18-25) completed online questionnaires measuring social anxiety and reactions to distressing social events. Antagonistic and non-antagonistic distressing social events were both related to social anxiety. Relationships between the frequencies of any distressing social events and social anxiety were mediated by reactions akin to posttraumatic stress. Responses to distressing social events were not influenced by the presence of an antagonist or betrayal. The results suggest that non-antagonistic distressing social events can be as distressing as antagonistic distressing social events and contribute to expanding evidence that reactions to distressing social events may resemble reactions to life-threatening events.

Bullying Behaviour And Substance Abuse Among Underage Psychiatric Inpatient Adolescents

Background and objective

Only a few studies have examined the putative association between substance use and bullying others, and to our knowledge none of the previous studies have investigated substance abuse among victims or those who are both bullies and victims. The aim of our study was to investigate substance use among all of these three bullying subgroups and to examine the putative association between substance use and bullying behaviour.

Methods

The study sample consisted of 508 Finnish adolescents (age 12–17) admitted to psychiatric inpatient care between April 2001 and March 2006. We used the Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL) to obtain DSM-IV psychiatric diagnoses, information about bullying behaviour and substance abuse of the adolescents. The level of nicotine dependence (ND) was assessed by using the modified Fagerström Tolerance Questionnaire (mFTQ).

Results

Our study showed that both among boys and girls, regular daily smoking and alcohol use among boys were statistically significantly associated with bullying behaviour. Further, among girls, but not among boys, there was also an association between bullying behaviour and more severe substance use, such as ND, use of cannabis and hard drugs.

Conclusion

Since an association between bullying and severe substance use was found in this study, our novel finding needs replication in adolescent general population samples.

Childhood adversity in association with personality disorder dimensions: New findings in an old debate

Background

Various studies have reported a positive relationship between child maltreatment and personality disorders (PDs). However, few studies included all DSM-IV PDs and even fewer adjusted for other forms of childhood adversity, e.g. bullying or family problems.

Method

We analyzed questionnaires completed by 512 participants of the ZInEP epidemiology survey, a comprehensive psychiatric survey of the general population in Zurich, Switzerland. Associations between childhood adversity and PDs were analyzed bivariately via simple regression analyses and multivariately via multiple path analysis.

Results

The bivariate analyses revealed that all PD dimensions were significantly related to various forms of family and school problems as well as child abuse. In contrast, according to the multivariate analysis only school problems and emotional abuse were associated with various PDs. Poverty was uniquely associated with schizotypal PD, conflicts with parents with obsessive-compulsive PD, physical abuse with antisocial PD, and physical neglect with narcissistic PD. Sexual abuse was statistically significantly associated with schizotypal and borderline PD, but corresponding effect sizes were small.

Conclusion

Childhood adversity has a serious impact on PDs. Bullying and violence in schools and emotional abuse appear to be more salient markers of general personality pathology than other forms of childhood adversity. Associations with sexual abuse were negligible when adjusted for other forms of adversity.

Did Bullying Victimization Decrease After Nationwide School-Based Antibullying Program? A Time-Trend Study

OBJECTIVE

We assessed changes in traditional and cyberbullying victimization, and their associations with mental health, before and after the introduction of a nationwide antibullying program in Finnish schools in 2009.

METHOD

This time-trend assessment comprised two methodologically identical cross-sectional survey studies, with 2,061 adolescents in 2008 (response rate 90.2%) and 1,936 in 2014 (91.8%). Their mean age was 14.4 years. They completed questionnaires about traditional and cyberbullying, mental health, and perceptions of school safety. Odds ratios (OR) and 95% CIs are presented with 2008 as the reference year.

RESULTS

From 2008 to 2014, traditional victimization decreased from 28.9% to 19.1% (odds ratio [OR] = 0.5, 95% CI = 0.4-0.7) among boys and from 23.2% to 17.4% (OR = 0.7, 95% CI = 0.6-0.9) among girls. Cyberbullying victimization remained fairly stable at 3.3% and 3.0% (OR = 0.7, 95% CI = 0.4-1.2) for boys and at 2.7% and 4.1% (OR = 1.4, 95% CI = 0.9-2.4) for girls. Combined traditional and cyberbullying victimization decreased from 6.1% to 3.9% (OR = 0.5, 95% CI = 0.4-0.8) among boys and from 7.5% to 6.7% (OR = 0.8, 95% CI = 0.6-1.2) among girls. Those experiencing both traditional and cyberbullying reported the highest mental health problems. Perceived school safety improved among boys, but not among girls. Both boys and girls reported greater efforts by teachers and fellow students to stop bullying.

CONCLUSION

Combined traditional and cyberbullying victimization was an indicator of comorbid mental health problems. Interventions that target both types of bullying, and that are integrated with mental health promotion, are needed.

Bullying and psychotic symptoms in youth with bipolar disorder

BACKGROUND

Childhood trauma is associated with psychosis in adults with bipolar disorder (BD). Although bullying represents a widespread form of childhood trauma, no studies thus far have investigated the association of bullying and psychosis in pediatric bipolar disorder (PBD). We aim to examine the association between psychosis in PBD with bullying victimization.

METHODS

We included 64 children and adolescents (age± mean= 12±3.43) outpatients with BD spectrum disorders. Psychiatric diagnoses were assessed with the semi- structured interview Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime (KSADS-PL) version with additional depression and manic symptom items derived from the Washington University in St. Louis Kiddie Schedule for Affective Disorders (WASH-U-KSADS). Bullying, demographic, and clinical variables were assessed during the clinical interview.

RESULTS

A lifetime history of psychotic symptoms was associated with bullying (p = 0.002), suicidal behavior (p = 0.006), low socioeconomic status (p = 0.04), and severity of PBD (p = 0.02). Only bullying (OR = 7.3; 95%CI = 2-32) and suicidal behavior (OR = 7.6; 95%CI = 1.5-47.8) remained significant after adjustment for confounders. In a supplementary analysis, we developed a model using supervised machine learning to identify the most relevant variables that differentiated participants with psychotic symptoms, which included bullying, Clinical Global Impression-Severity scale (CGI-S), and suicidal behavior (accuracy = 75%, [p = 0.03]; sensitivity = 77.91%; specificity = 69.05%; area under the curve [AUC] = 0.86).

LIMITATIONS

Small sample, cross-sectional design, and generalizability of findings beyond the outpatient clinical sample.

CONCLUSIONS

Findings underscore the importance of assessing bullying in PBD participants. Future longitudinal studies with larger samples are needed to replicate our findings and determine causality.
