Predicting bullying and victimization among early adolescents: Associations with disruptive behavior disorders

Associations of vegetable and fruit intake, physical activity, and school bullying with depressive symptoms in secondary school students: the mediating role of internet addiction

BACKGROUND

Few studies have simultaneously focused on the associations of vegetable and fruit intake, physical activity, school bullying, and Internet addiction (IA) with depressive symptoms. This study aimed to explore the direct and indirect effects of the above factors on depressive symptoms in adolescents by constructing a structural equation model (SEM).

METHODS

This study was conducted in Qingdao from September to November 2021. A total of 6195 secondary school students aged 10-19 years were included in the analysis. Information on all variables was assessed using a self-administered questionnaire. An SEM was constructed with depressive symptoms as the endogenous latent variable, IA as the mediating variable, and vegetable and fruit intake, physical activity, and school bullying as the exogenous latent variables. The standardized path coefficients (β) were the direct effects between the latent variables, and the indirect effects were obtained by the product of direct effects between relevant latent variables.

RESULTS

The median value with the interquartile range of depressive symptom scores was 7 (3,12). Vegetable and fruit intake (β=-0.100, P<0.001) and physical activity (β=-0.140, P<0.001) were directly negatively related to depressive symptoms. While school bullying (β=0.138, P<0.001) and IA (β=0.452, P<0.001) were directly positively related to depressive symptoms. IA had the greatest impact on depressive symptoms. Vegetable and fruit intake, physical activity, and school bullying could not only directly affect depressive symptoms, but also indirectly affect depressive symptoms through the mediating effect of IA, the indirect effects and 95% confidence intervals (CIs) were -0.028 (-0.051, -0.007), -0.114 (-0.148, -0.089) and 0.095 (0.060, 0.157), respectively. The results of the multi-group analysis showed that the SEM we constructed still fit in boy and girl groups.

CONCLUSIONS

The results indicated that vegetable and fruit intake, physical activity, school bullying, and IA had a significant direct impact on depressive symptoms, among which IA had the greatest impact. In addition, both vegetable and fruit intake, school bullying, and physical activity indirectly affected depressive symptoms through the mediating effect of IA. The impact of IA on depressive symptoms should be given extra attention by schools and parents. This study provides a scientific and effective basis for the prevention and control of adolescent depressive symptoms.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Traditional bullying, cyberbullying, and quality of life among adolescents in 35 countries: Do cultural values matter?

RATIONALE

Substantial evidence indicates that involvement in school bullying has been linked to lower quality of life (QoL). Yet there is little information elucidating the link between bullying involvement and QoL in different cultures.

OBJECTIVE

This study investigated the associations between different types of bullying involvement and QoL among adolescents. The moderating roles of cultural values in the relationship between bullying involvement and QoL were examined.

METHODS

This study included representative samples from 35 countries (N = 184,017) using data from the 2017/2018 Health Behavior in School-Aged Children (HBSC) survey and the new 2023 World Cultural Map Scores from the World Values Survey Wave 7 (2017/2021). Multilevel mixed-effects analysis was employed to examine individual-level and country-level effects simultaneously.

RESULTS

All types of bullying involvement were associated with lower QoL, with being a victim having the lowest QoL. Adolescents in societies that prioritize higher self-expression values exhibited a reduced propensity to engage in school bullying. In countries with higher self-expression values, there was a more pronounced negative association between bullying involvement and QoL. Traditional/Secular-rational values had no significant and consistent moderating effect on the association between bullying involvement and QoL. Those results were quite similar for both traditional bullying and cyberbullying.

CONCLUSION

These findings imply that cultural values are closely intertwined with adolescent bullying and quality of life. Therefore, prevention and intervention programs should pay more attention to addressing bullying and promoting the QoL of adolescents according to various cultural values.

Parenting practices, bullying perpetration, and conduct problems among Ukrainian children

BACKGROUND

Positive and consistent parenting practices are associated with the positive mental health of children. However, little is understood about the implications of the Russian military invasion on family dynamics in Ukraine.

OBJECTIVE

This research aims to estimate the prevalence of childhood conduct disorder (CD) and bullying perpetration and their association with parenting practices among Ukrainian children living in proximity to the war.

PARTICIPANTS AND SETTING

The sample included 2763 Ukrainian children ranging in age from 10 to 17 years (M = 12.6, SD = 1.23), 56.23 % girls. Children attended public secondary schools in Eastern Ukraine, mostly in Kharkiv and Kharkiv oblasts (regions).

METHODS

Children reported on sociodemographic characteristics, parenting practices, CD, and bullying perpetration using smartphones, computers, or tablets, at home or in school IT classrooms. Data were collected on a secure online platform.

RESULTS

Children reported teasing (23.68 %), spreading rumors (24.51 %), helping to harass (17.31 %), threatening to hurt or hit (21.65 %) other students, breaking rules (28.13 %), getting in fights (17.13 %), cheating (43.16 %), and being spanked by parents (30 %). Also, 1.83 % of girls and 3.43 % of boys met a borderline cutoff for CD. Lack of parent involvement was associated with increased CD and bullying risks. Poor parent monitoring, inconsistent discipline, and corporal punishment were associated with increasaed CD but not with bullying. CD mediated the association of poor monitoring, inconsistent discipline, and corporal punishment with bullying.

CONCLUSION

Parental involvement, monitoring, consistent discipline, and avoidance of physical punishments are important practices that can reduce disruptive behavior and aggressive tendencies among Ukrainian children affected by the Russian war.

Childhood Bullying as a Risk Factor for Late-Life Psychological Distress and Cognitive Impairment

In the United States, non-Hispanic Black (19%) older adults are more likely to develop dementia than White older adults (10%). As genetics alone cannot account for these differences, the impact of historical social factors is considered. This study examined whether childhood and late-life psychological distress associated with dementia risk could explain part of these disparities. Using longitudinal data from 379 White and 141 Black respondents from the Panel Study of Income Dynamics, we assessed the association between childhood bullying and late-life dementia risk, testing for mediation effects from late-life psychological distress. Mediation analysis was computed via negative binomial regression modeling, stratified by race (White/Black), type of bullying experience (target, bully, and bully-target), and the age range at which the experience occurred (6-12, 13-16). The results indicated that late-life psychological distress fully mediated the association between Black respondents who were bullies and dementia risk. However, no significant association was observed among White respondents. These results suggest that interventions aimed at preventing and treating psychological distress throughout the lifespan could be crucial in mitigating the development and progression of dementia risk.

Prevalence of Aggressive Behavior in Greek Elementary School Settings from Teachers' Perspectives

The present study aims to estimate the prevalence of bullying in Greek elementary schools and to study the risk factors that lead to bullying episodes. A structured questionnaire was given to 221 teachers of elementary schools and 71 kindergarten teachers from urban and rural Greek schools. They were asked to note the forms and the frequency of aggressive behaviors that they had witnessed during the school years 2020-2021 and 2021-2022, as well as the sociodemographic characteristics of the aggressive children involved. Statistical analyses of the data were conducted, and the obtained results show that specific forms of aggression are significantly correlated with gender and low academic performance. In addition, there is no form of aggressive behavior that is associated with the perpetrator's age, nationality or family status. Further, the results of the factor analysis revealed four dominant factors in the aggressive behavior observed by teachers. The forms of bullying and the prevailing factors of aggressive behavior that dominate in Greek school settings are reported in the present study. Furthermore, a novel evaluation tool for teachers could potentially be developed based on the results of the present study.

Bidirectional associations between self-esteem and relational aggression from 5th to 11th grade

A widely held belief among laypeople and psychologists suggests that self-esteem and relational aggression (i.e., perpetration and victimization) are associated over time. The present study examines the bidirectional associations between self-esteem and relational aggression across 6 years, using two types of longitudinal models (latent cross-lagged panel models and latent random intercepts cross-lagged panel models) to separate between- and within-person effects. Six hundred and seventy-four Mexican-origin youth reported their global and domain-specific self-esteem and relational aggression (perpetration and victimization) in the fifth, seventh, ninth, and eleventh grades. Our findings suggest that: (a) being a perpetrator is prospectively associated with later lower opposite-sex relationships self-esteem at the between-person level, (b) lower self-esteem in the domain of honesty-trustworthiness is prospectively associated with becoming a perpetrator and a victim at the within- and between-person level, (c) lower global self-esteem is prospectively associated with higher victimization at the between-person level, and (d) being victimized is not prospectively associated with later global or domain-specific self-esteem, at neither the within- nor the between-person level. The present study provides little evidence for the widely held belief about the bidirectional associations between self-esteem and relational aggression across time but demonstrates the complexity of these associations on the between- and within-person level.

Children's mobile-gaming preferences, online risks, and mental health

This study examined the relationships between children's mobile gaming preferences, online risks, and mental health. Data were obtained from a sample of 2,702 third and fourth grade students from 16 elementary schools in Taiwan and 9 schools in China. A self-administered questionnaire was used. The mental state of the children who participated in the study was assessed using the Strengths and Difficulties Questionnaire (SDQ), while mobile gaming addiction was assessed using the short form of the Internet Gaming Disorders Scale (IGDS9-SF). The results showed that about 54% of children played mobile games with others (multi-player), while 31% played mobile games alone, and 15% did not play mobile games. Multiple logistic regression results indicated that behaviors such as participating in multi-player games, playing violent games, a poor parent-child relationship, and living in a rural area were associated with a greater risk of mobile gaming addiction. Involvement in multi-player games, playing violent games, mobile gaming addiction, and exposure to mobile violence/pornography were associated with greater risks of cyber aggression/victimization. Multiple regression results showed that being a multi-player, playing violent games, mobile gaming addiction, exposure to violence/pornography, exposure to cyber aggression/victimization, and having a poor parent-child relationship were associated with emotional and behavioral problems.

Factors Associated With Bullying Victimization and Bullying Perpetration in Children and Adolescents With ADHD: 2016 to 2017 National Survey of Children's Health

OBJECTIVE

To identify characteristics associated with bullying involvement in pediatric ADHD.

METHODS

Data from the 2016 to 2017 National Survey of Children's Health for children aged 6 to 17 years with ADHD were evaluated to assess the association between parent-reported bullying victimization or perpetration and the following potential predictors: demographic characteristics, family factors, school factors, and child conditions/behaviors.

RESULTS

Among children with ADHD, 46.9% were bullying victims and 16.2% were perpetrators. Factors associated with victimization included having family financial strain, developmental delay or intellectual disability, friendship difficulties, and school reports about problems. Factors linked to perpetration included being male, receiving government assistance, lack of school engagement, school reports about problems, and having difficulties with friendships, staying calm, and arguing.

CONCLUSIONS

Children with ADHD frequently were bullying victims and sometimes bullying perpetrators. Factors related to family financial strain, developmental disabilities, emotional regulation, peer relationships, and school functioning may help to identify risk for bullying and opportunities for anti-bullying interventions.

Evaluation of a cyberbullying prevention program in elementary schools: The role of self-esteem enhancement

Although elementary schools are considered a fertile ground for promoting positive behaviors among students (such as safe online practices), to date, almost no study has examined the effectiveness of a cyberbullying prevention program among elementary school students of typical and non-typical development. The present study evaluated the effectiveness of such a school-based European funded preventive program (TABBY, Threat Assessment of Bullying Behavior in Youth) among sixth graders with and without special educational needs (SEN). The study also examined the predictive role of self-esteem in students’ cyberbullying involvement. Overall, 240 students from randomly selected Greek schools completed a self-report questionnaire, which included a scale on cyberbullying and self-esteem. Following an experimental longitudinal research design, the intervention was applied to the experimental (N = 120) but not to the control group of students (N = 120). Each group consisted of both students with (N = 60) and without SEN (N = 60). The evaluation was based on the completion of the self-report questionnaire before (1^st phase), immediately after (2^nd phase), and 6 months after the intervention was completed (3^rd phase) by trained general and special education teachers. According to the findings, students’ cyberbullying engagement (as bullies/victims) decreased significantly in the second and third phase, and especially for those with SEN. Additionally, self-esteem negatively predicted students’ involvement in cyberbullying (as bullies/victims) in all three phases. The findings partially support the appropriateness of interventions within the elementary school context in order to enhance self-esteem and promote a safe online culture among students of typical as well as atypical development.

Subtypes of Bullying and Types of Substance Use among Urban African American Adolescents: Who Is Likely to Use What?

The present study examined the types of drugs likely to be used by bullies, victims, and bully/victims. Participants comprise African American adolescents from three high schools, one youth church group, two community youth programs, and four public venues in low-income communities in Chicago's Southside. A series of logistic regression analyses and latent class analyses were employed. Victims are likely to use alcohol, marijuana, and lean/krokodil. Bullies were likely to use alcohol and marijuana. Bully/victims were not at risk of any of the substances. Our LCA findings revealed a lower occurrence of substance use among victims although 30% used alcohol and marijuana; more than half of bullies showed high levels of alcohol, marijuana, and lean/krokodil use; a diverse pattern of drug use was shown among bully/victims although their lean/krokodil and crack/cocaine use was higher than other subgroups of bullying. The drugs of choice for African American bullies, victims, or bully/victims are variable.

Conduct problems among children in low-income, urban neighborhoods: A developmental psychopathology- and RDoC-informed approach

Conduct problems are associated with numerous negative long-term psychosocial sequelae and are among the most frequent referrals for children's mental health services. Youth residing in low-income, urban communities are at increased risk for conduct problems, but not all youth in these environments develop conduct problems, suggesting heterogeneity in risk and resilience processes and developmental pathways. The present study used a developmental psychopathology- and Research Domain Criteria (RDoC)-informed approach for conceptualizing risk and resilience for conduct problems among children from low-income, urban neighborhoods. Participants were 104 children (M = 9.93 ± 1.22 years; 50% male; 96% African American, 4% Latinx). We assessed four constructs reflecting cognitive and neurobiological processes associated with conduct problems using multiple levels of analysis and informants: autonomic nervous system reactivity, limbic system/orbitofrontal cortical functioning, dorsolateral prefrontal cortical functioning, and conduct problems. Latent profile analysis identified four profiles: typically developing (TD, n = 34); teacher-reported conduct problems (TCP, n = 14); emotion processing (EP, n = 27); and emotion expression recognition (EER, n = 29). External validation analyses demonstrated that profiles differed on various indices of conduct problems in expected ways. The EP profile exhibited lower levels of emotional lability and callous–unemotional behaviors, and higher levels of prosocial behavior. The TD profile demonstrated elevated emotional lability. Implications for etiological and intervention models are presented.

Perpetration and Victimization in Offline and Cyber Contexts: A Variable- and Person-Oriented Examination of Associations and Differences Regarding Domain-Specific Self-Esteem and School Adjustment

Self-esteem has been identified as a predictor of bullying perpetration and victimization, which, in turn, may lead to school adjustment problems. However, findings regarding the direction and strength of these associations have been inconclusive. This study aimed to resolve this by differentiating between offline and cyber contexts and various self-esteem domains. An online sample of 459 adolescents retrospectively completed measures of self-esteem domains and offline/cyber perpetration and victimization, and a subsample of 194 adolescents also completed measures of loneliness and school adjustment. A mediation analysis of bullying-related variables on the effect of self-esteem domains on school adjustment indicated that offline victimization was the only significant mediator. Positive indirect effects were found for social and emotional self-esteem, and negative indirect effects were found for school performance-related self-esteem. Furthermore, person-oriented analyses examined differences in bullying-related roles regarding self-esteem domains, loneliness, and school adjustment. Victim groups showed lower self-esteem in many domains, but cyber victims showed higher body-related self-esteem. Bullies showed lower school performance-related but higher social self-esteem. Both bullies and victims showed lower school adjustment and more loneliness. Implications for theory and practice are discussed, as the findings are relevant for teachers and could be used to develop and deploy more effective anti-bullying programs.

Traditional school bullying and cyberbullying: Prevalence, the effect on mental health problems and self-harm behavior

Bullying is widely recognized as a major psychosocial problem with substantial negative consequences. The current study aimed to estimate the prevalence of traditional school bullying and cyberbullying and reciprocal associations between bullying involvement and mental health problems. The sample of the study consisted of 6202 middle and high school students (age 11-18, M= 14.4 ±1.9 years, 54% boy). Bullying involvement, self-harm behavior, anxiety, depression, and psychosocial difficulties were assessed by self-report questionnaire. The prevalence of traditional school bullying and cyberbullying victimization was 33% (95% CI 32.1-34.5%) and 17% (95% CI 16.3-18.2%), respectively. The prevalence of traditional school bullying and cyberbullying perpetration was 22.4% (95% CI 21.3-23.4%) and 10.4% (95% CI 9.7-11.3%), respectively. Bullying involvement -as a victim, perpetrator, or both- was associated with anxiety, depression, psychosocial difficulties, and self-harm behavior. Girls were more likely to be affected than boys in mental health outcomes. A significant association between bullying victimization and negative mental health outcomes were also observed. These findings provide evidence to intervention strategies need to target both traditional and cyberbullying involvement. Understanding the risk profile will help create useful and appropriate interventions, which will reduce the early effect of bullying on mental health and modify the clinical course.

Parent- and teacher-reported long-term effects of parent training on child conduct problems in families with child protection and other support services: a randomized controlled trial

BACKGROUND

This randomized controlled trial (RCT) evaluated the long-term effectiveness of the Incredible Years^® (IY) Parenting Program in modifying children's externalizing problems among families in Child Protection Services (CPS) and using other special support services. We also examined whether parent-reported effects of the IY^® generalize to the daycare/school setting as reported by teachers.

METHODS

Participants in the study were 3-7-year-old children with behavioural problems (N = 102 at baseline, N = 89 at one-year follow-up). Participants were randomized to intervention (N = 50) and control groups (N = 52) after the baseline assessment. The intervention group received 19-week IY^® Parenting Program. The effectiveness of the intervention was analyzed using linear mixed model.

RESULTS

Our previously reported pre-post intervention effects on CBCL (Child Behavior Checklist) and ECBI (Eyberg Child Behavior Inventory) were not sustained to the one-year follow-up. Child conduct problems decreased from baseline to follow-up in both intervention and control groups. The positive changes were not observed at daycare/school from baseline to post-intervention or to the one-year follow-up, and there were no significant differences in changes between the groups.

CONCLUSIONS

Evidence-based parenting program IY^® seems to be an effective intervention for child conduct problems in the short term in families in the CPS context, but sustaining the positive effects and generalizing them to the daycare/school context are challenging.

TRIAL REGISTRATION

The trial is registered in the ClinicalTrials.gov registry (NCT03239990), Registered August 4th, 2017; https://clinicaltrials.gov/ct2/results?cond=&term=NCT03239990&cntry=&state=&city=&dist=.

A multilevel analysis of the influence of bullying participant roles upon the trajectories of adolescents’ social and emotional competencies

This study analyzed how social and emotional competencies evolved according to adolescents’ involvement in bullying, and whether gender influenced social and emotional competencies’ development. Five-hundred-fourteen students ( Mage = 12.71; SD = 1.09) were assessed through self-reports at three different time points for one year. Results showed that students involved in the three analyzed bullying roles displayed a more negative trajectory in all but one social emotional competence analyzed compared to students not involved in bullying. The exception was students who bullied others for responsible decision making. Additionally, gender differences were only found in self-esteem trajectories; boys displayed a more pronounced decrease. In larger classes, students displayed higher levels of self-control, social awareness and responsible decision-making. These results showed that reduced social and emotional competencies were a consequence of bullying involvement for every bullying role analyzed.

Prevalence, correlates, and experiences of school bullying among adolescents: A national study in Jordan

School bullying is recognized as a global problem and sparks public concerns for students’ safety. While it has recently emerged as a critical concern in the Arab world, particularly in Jordan, no national studies have yet investigated the extent of bullying in Jordanian schools. The purpose of this study was to investigate the prevalence, correlates, and experiences of bullying among a national sample of Jordanian adolescent students. A stratified random sampling procedure was used to select schools that represent the three main regions of Jordan (i.e. north, middle, and south) and a weighted sample of schools was randomly selected using Statistical Analysis System 9.4 based on provinces’ density. A nationally representative sample of 1083 adolescents aged 12 to 17 was included in the study. Data were collected using self-administered questionnaires on school bullying and adolescent sociodemographics. The prevalence of bullying among Jordanian adolescents was consistent with international studies; 7% reported their involvement in bullying as a victim, 7.6% as a bully, and 1.7% as both. Verbal bullying was the most common form of bullying among victims and bully-victim, while relational bullying was the most prevalent bullying for bullies. Being a perpetrator was more prevalent among boys than girls. Adolescent students who came from low socioeconomic status or whose fathers were illiterate reported more victimization experience. The majority of students who experienced bullying reported negative attitudes of bystanders, parents, and teachers towards intervening or responding to the bullying experience. Bullying exists among Jordanian students and active steps towards addressing this phenomenon are discussed. This is the first known Jordanian study representing a national sample of adolescent students’ experience of bullying. Findings present valuable information for school professionals, parents, and students regarding bullying and its associated factors. These findings also provide an avenue for the adoption and implementation of available anti-bullying programs to ameliorate bullying behaviors among Jordanian school students.

ADHD, suicidal ideation, depression, anxiety, self-esteem, and alcohol problem in Korean juvenile delinquency

The purpose of this study is to evaluate the prevalence rates of externalizing symptom, ADHD, as well as internalizing symptoms, depression, anxiety, suicidal ideation, self-esteem, and alcohol problem in Korea juvenile delinquency for the first time in Korea. A case-control study design was used. It also examined the associations with ADHD, suicidal ideation, depression, anxiety, self-esteem, and alcohol problem between the Juvenile Delinquency group and the comparison group in Korea.A series of questionnaires were provided to a total of 251 participants (149 from the juvenile delinquency group and 102 from the comparison group) from October 2015 to December 2015 in Korea. All participants were evaluated using KARS, SSI, BDI, BAI, RSI, and CAGE. This study showed the relationship between ADHD, suicidal ideation, depression, anxiety, self-esteem, and alcohol problem in Korean juvenile delinquency. Also this study showed that ADHD and self-esteem were important factors in predicting juvenile delinquency. Therefore, in order to prevent juvenile delinquency, special attention, and consideration are needed for adolescents with high ADHD or low self-esteem.

Trajectories of Verbal and Physical Peer Victimization Among Children with Comorbid Oppositional Defiant Problems, Conduct Problems and Hyperactive-Attention Problems

The high levels of comorbidity between oppositional/conduct problems and hyperactivity/attention problems underscore the need for assessing how vulnerability for peer victimization is shaped by overlap among these behavior problems. Children (mean age 8.39, SD = 0.93) participating in a longitudinal study of the development of conduct problems (N = 744; 348 girls) in Quebec, Canada, were evaluated by their teachers regarding experiences of peer verbal and physical victimization every year for 6 years. Parent and teacher ratings of clinically significant oppositional/conduct problems, and hyperactivity/attention problems, as well as cormorbid opposition defiant/conduct problems and hyperactivity/attention problems were regressed onto trajectories of verbal and physical victimization. While behavior problems (both alone and together) were associated with higher levels of verbal and physical victimization, some variation was observed across rater and type of victimization. Ultimately, these findings suggest the importance of adapting programming for reducing victimization to children with oppositional and conduct problems.

Investigating Construct Validity of the Cyber-Peer Experiences Questionnaire

Abstract. Cyberaggression and cybervictimization have gained momentum as a research focus given associated mental health sequelae. To date, however, there remains little consensus on the conceptualization and measurement of these constructs. The purpose of this study was to explore construct validity evidence for the Cyber-Peer Experiences Questionnaire (C-PEQ), a novel measure that assesses experiences of cyberaggression and cybervictimization. Undergraduate participants ( n = 735) completed an online survey including the C-PEQ and other theoretically related instruments. Confirmatory factor analysis did not provide support for the hypothesized two-factor model [MLM χ2(125) = 293.58, RMSEA = .06, CFI = .87, SRMR = .06]. The C-PEQ displayed evidence for internal consistency reliability. Evidence for convergent validity with theoretically similar constructs was mixed. Specific areas of model misspecification included items 1 and 2 on both subscales (altering social media friend lists). Future research may explore additional construct validity evidence of the C-PEQ in novel samples with these items removed.

Developmental Precursors of Relational Aggression From Late Childhood Through Adolescence

Relational aggression-a psychological form of aggression-has numerous negative consequences for physical and emotional health. However, little is known about the risk factors that lead youth to engage in relational aggression. Using multimethod data from a longitudinal research of 674 Mexican-origin youth, this study examined the influence of parents, siblings, and peers on the development of relational aggression. Increases in relational aggression from age 10 to 16 were associated with: (a) low levels of parental monitoring and (b) increased association with deviant peers and siblings. These results held across gender and nativity status. The findings suggest that multiple socialization agents contribute to the development of relational aggression. We discuss the practical implications for reducing relational aggression during adolescence.

The Co-Development of Relational Aggression and Disruptive Behavior Symptoms from Late Childhood through Adolescence

Researchers have debated whether relational aggression is a developmentally-normative behavior or a sign of some underlying psychopathology. However, due to the dearth of longitudinal studies, we know little about how relational aggression and more severe forms of disruptive behavior co-develop. The present study examined bidirectional associations between relational aggression and two psychiatric disorders, Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD), using data from a longitudinal study of 674 Mexican-origin youth followed from age 10 to 16. Results showed that individuals who engaged in relational aggression tended to increase over time in ODD and CD symptoms, and conversely, individuals exhibiting symptoms of ODD and CD tended to increase in relational aggression. These findings held for boys and girls, for youth born in Mexico and the U.S., and after controlling for physical aggression. Thus, relational aggression seems to be both a developmentally-normative behavior and a predictor of future mental health problems.

School Violent Victimization Among Youth: Is There an Association With Perceived School Safety?

Violent victimization and school safety continues to be a major health concern in the United States. This study examines whether there is an association between school violent victimization and perceived school safety among youth. The PRIDE Questionnaire for 6th-through 12th-grade students, which assesses violent victimization and perceived school safety, was completed voluntarily by students (N = 54,938) in a large Midwestern city. Results indicated that a sizeable percentage of youth felt unsafe at school. Perceived school safety differed based on gender, grade, and race. Students experiencing violent victimization reported lower levels of school safety than their counterparts did. Such findings have important implications for school health professionals and prevention specialists interested in protecting youth from violent victimization and enhancing student safety at school.

Initial Development and Validation of the BullyHARM: The Bullying, Harassment, and Aggression Receipt Measure

This article describes the development and preliminary validation of the Bullying, Harassment, and Aggression Receipt Measure (BullyHARM). The development of the BullyHARM involved a number of steps and methods, including a literature review, expert review, cognitive testing, readability testing, data collection from a large sample, reliability testing, and confirmatory factor analysis. A sample of 275 middle school students was used to examine the psychometric properties and factor structure of the BullyHARM, which consists of 22 items and 6 subscales: physical bullying, verbal bullying, social/relational bullying, cyber-bullying, property bullying, and sexual bullying. First-order and second-order factor models were evaluated. Results demonstrate that the first-order factor model had superior fit. Results of reliability testing indicate that the BullyHARM scale and subscales have very good internal consistency reliability. Findings indicate that the BullyHARM has good properties regarding content validation and respondent-related validation and is a promising instrument for measuring bullying victimization in school.

Bidirectional Pathways between Relational Aggression and Temperament from Late Childhood to Adolescence

Relational aggression is linked to numerous adverse consequences. However, we know little about how temperament leads individuals to become perpetrators/victims of relational aggression, or how being a perpetrator/victim influences the development of temperament. We used longitudinal data from 674 Mexican-origin youth to examine relations between relational aggression and mother- and child-reported temperament from 5^th grade (M_age=10.8; SD=0.60) through 11^th grade (M_age=16.8; SD=0.50). Results show that: (a) high Negative Emotionality and low Effortful Control predicted increases in victimization; (b) low Effortful Control predicted increases in perpetration; (c) victims increased in Negative Emotionality and decreased in Effortful Control; and (d) perpetrators increased in Negative Emotionality and Surgency. Thus, temperament serves as both an antecedent to and a consequence of relational aggression.

Escala de Comportamentos de Bullying (ECB): Elaboração e Evidências Psicométricas

Resumo Este estudo objetivou elaborar a Escala de Comportamentos de Bullying (ECB), checando evidências de validade e precisão. Participaram 455 estudantes do ensino fundamental de escolas públicas e particulares de Parnaíba (PI), com idade média de 11,3 anos, em maioria do sexo feminino (53,5%). Todos responderam à versão preliminar da medida, de 30 itens, e perguntas demográficas. Realizou-se a análise dos eixos principais (AEP) (rotação Varimax), o Scree Test, e a análise paralela indicou a existência de uma estrutura tetrafatorial. Logo, realizou-se uma nova AEP, fixando a extração de quatro fatores, estes explicaram conjuntamente 47,7% da variância total, cujos alfas de Cronbach variaram de 0,60 a 0,79. Esses achados revelam que a ECB reúne evidências favoráveis de validade e consistência interna, podendo ser adequadamente utilizada em estudos futuros para conhecer os antecedentes e consequências do bullying.

Physical Child Abuse and Teacher Harassment and Their Effects on Mental Health Problems Amongst Adolescent Bully-Victims in Taiwan

This study compared physical child abuse and teacher harassment of bully-victims with other groups and examined their associations with mental health problems in bully-victims. For 6,160 adolescents, experiences of physical child abuse, teacher harassment, peer bullying, and six mental health problem indicators were assessed. Adolescents that had experienced physical child abuse and teacher harassment were more likely to be bully-victims but not neutral or pure victims. Adolescents who reported physical child abuse were more likely to be bully-victims but not pure bullies. Bully-victims that had experienced teacher harassment exhibited more severe depression and insomnia than did those without teacher harassment. Gender had moderating effects on the difference in physical child abuse between bully-victims and neutrals and on the association between physical child abuse and suicidality in bully-victims. Physical child abuse and teacher harassment should be considered when preventive and intervention programs are developed for adolescents.

Preschool Attention-Deficit/Hyperactivity and Oppositional Defiant Problems as Antecedents of School Bullying

OBJECTIVE

To examine whether early manifestations of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) increase children's later risk of bullying or victimization.

METHOD

Using a population-based, prospective cohort, our multi-informant approach comprised reports of parents, teachers, and peers. ADHD and ODD behavioral problems at ages 1.5, 3, and 5 years were determined from parental reports on the Child Behavior Checklist. Later bullying behavior at school was reported by teachers using a questionnaire (n = 3,192, mean age 6.6 years), and by peer/self-reports using peer nominations (n = 1,098, mean age 7.6 years). We examined the following: whether problem behavior scores at age 1.5, 3, or 5 years predicted a risk of bullying involvement; and whether high or increasing behavioral problems throughout ages 1.5 to 5 years were associated with bullying involvement at school. Analyses were adjusted for a range of child and maternal covariates.

RESULTS

Behavioral problems at a young age each predicted later bullying involvement at school. For example, higher ADHD problem scores at age 3 years were associated with the risks of becoming a bully or a bully-victim (ORBULLY = 1.20, 95% CI = 1.07-1.35 [teacher report], ORBULLY-VICTIM = 1.28, 95% CI = 1.14-1.43 [teacher report], and ORBULLY-VICTIM = 1.35, 95% CI = 1.03-1.78 [peer/self-report]). Children whose behavioral problem scores were high or increased over time consistently had elevated risks of becoming a bully or a bully-victim.

CONCLUSION

Behavioral problems at a young age may predispose children to bullying involvement in early elementary school.

A shared genetic propensity underlies experiences of bullying victimization in late childhood and self-rated paranoid thinking in adolescence

BACKGROUND

Bullying is a risk factor for developing psychotic experiences (PEs). Whether bullying is associated with particular PEs, and the extent to which genes and environments influence the association, are unknown. This study investigated which specific PEs in adolescence are associated with earlier bullying victimization and the genetic and environmental contributions underlying their association.

METHOD

Participants were 4826 twin pairs from a longitudinal community-based twin study in England and Wales who reported on their bullying victimization at the age of 12 years. Measures of specific PEs (self-rated Paranoia, Hallucinations, Cognitive disorganization, Grandiosity, Anhedonia, and parent-rated Negative Symptoms) were recorded at age of 16 years.

RESULTS

Childhood bullying victimization was most strongly associated with Paranoia in adolescence (r = .26; P < .01), with weaker associations with Hallucinations, Cognitive Disorganization, parent-rated Negative Symptoms (r = .12-.20; P < .01), Grandiosity (r = .04; P < .05), and Anhedonia (r = .00, n.s.). Bivariate twin model-fitting demonstrated that bullying victimization and Paranoia were both heritable (35% and 52%, respectively) with unique environmental influences (39% and 48%, respectively), and bullying victimization showed common environmental influences (26%). The association between bullying victimization and Paranoia operated almost entirely via genetic influences (bivariate heritability = 93%), with considerable genetic overlap (genetic correlation = .55).

CONCLUSION

In contrast to the assumed role of bullying victimization as an environmental trigger, these data suggest that bullying victimization in late childhood is particularly linked to self-rated Paranoia in adolescence via a shared genetic propensity. Clinically, individuals with a history of bullying victimization are predicted to be particularly susceptible to paranoid symptoms.

Does forgiveness mediate the impact of school bullying on adolescent mental health?

OBJECTIVE

The link between both bullying and victimisation and psychopathology has been well established. Forgiveness has been associated with better mental health. However, few studies have examined the relationship between adolescent forgiveness, psychopathology and bullying/victimisation. This study investigated forgiveness as a mediator of the adverse mental health problems experienced by bullies and victims of bullying.

METHOD

Participants were 355 Year 10 or Year 11 pupils (age = 14.9 years) from two British secondary schools in 2007, who completed self-administered measures on bullying and victimisation, mental health, forgiveness of self and others, and forgivingness. The mediating influence of forgiveness on the impact of bullying/victimisation on mental health was tested with a structural equation model.

RESULTS

Data from 55.6% of the 639 eligible pupils were analysed. Results confirmed an association between bullying/victimisation, forgiveness and psychopathology. Forgiveness scores were found to play a mediating role between bullying/victimisation and psychopathology.

CONCLUSIONS

Victimised adolescents who were better able to forgive themselves were more likely to report lower levels of psychopathology, while bullying adolescents who were unable to forgive others were more likely to report higher levels of psychopathology. This suggests a greater role for forgiveness within future research, intervention and policy on bullying. Forgiveness can form a valuable part of preventative and educational anti-bullying programmes.

A latent class analysis of bullies, victims and aggressive victims in Chinese adolescence: relations with social and school adjustments

This study used the latent class analysis (LCA) to identify and classify Chinese adolescent children's aggressive behaviors. It was found that (1) Adolescent children could be divided into four categories: general children, aggressive children, victimized children and aggressive victimized children. (2) There were significant gender differences among the aggressive victimized children, the aggressive children and the general children. Specifically, aggressive victimized children and aggressive children had greater probabilities of being boys; victimized children had equal probabilities of being boys or girls. (3) Significant differences in loneliness, depression, anxiety and academic achievement existed among the aggressive victims, the aggressor, the victims and the general children, in which the aggressive victims scored the worst in all questionnaires. (4) As protective factors, peer and teacher supports had important influences on children's aggressive and victimized behaviors. Relative to general children, aggressive victims, aggressive children and victimized children had lower probabilities of receiving peer supports. On the other hand, compared to general children, aggressive victims had lower probabilities of receiving teacher supports; while significant differences in the probability of receiving teacher supports did not exist between aggressive children and victimized children.

Association between school bullying levels/types and mental health problems among Taiwanese adolescents

BACKGROUND

Few studies have compared the risks of mental health problems among the adolescents with different levels and different types of bullying involvement experiences.

METHOD

Bullying involvement in 6,406 adolescents was determined through use of the Chinese version of the School Bullying Experience Questionnaire. Data were collected regarding the mental health problems, including depression, suicidality, insomnia, general anxiety, social phobia, alcohol abuse, inattention, and hyperactivity/impulsivity. The association between experiences of bullying involvement and mental health problems was examined. The risk of mental health problems was compared among those with different levels/types of bullying involvement.

RESULTS

The results found that being a victim of any type of bullying and being a perpetrator of passive bullying were significantly associated with all kinds of mental health problems, and being a perpetrator of active bullying was significantly associated with all kinds of mental health problems except for general anxiety. Victims or perpetrators of both passive and active bullying had a greater risk of some dimensions of mental health problems than those involved in only passive or active bullying. Differences in the risk of mental health problems were also found among adolescents involved in different types of bullying.

CONCLUSIONS

This difference in comorbid mental health problems should be taken into consideration when assessing adolescents involved in different levels/types of bullying.

Further evaluation of associations between attention-deficit/hyperactivity and oppositional defiant disorder symptoms and bullying-victimization in adolescence

Relations between symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) and bullying-victimization in adolescence are not yet clear. Accordingly, the current study evaluated these associations, with attention to gender differences, in a sample of predominantly Latino 9th-12th grade students (52.6 % male; mean grade level = 10.35, SD = 1.11). Further, the role of peer delinquency in these associations was evaluated. Findings indicated that ODD symptoms were more strongly associated with both bullying and victimization than ADHD symptoms, and the effects of ODD symptoms on physical forms of both bullying and victimization were stronger for males than females. The association between ODD symptoms and physical bullying was stronger at high levels of peer delinquency when compared to low levels of peer delinquency for both males and females. The role of peer delinquency in the link between ADHD symptoms and bullying and victimization appears to be gender specific and in need of further evaluation. Implications for the need to focus primarily on ODD symptoms for both bullying and victimization prevention and intervention are discussed.

Cyber-Bullying, Personality and Coping among Pre-Adolescents

The aim of this study was to investigate the association of personality (Five Factor Model), coping and cyber-bullying/victimization experiences among 300 Greek pre-adolescent students attending the upper two primary school grades. Boys reported more frequent involvement in cyber-bullying incidents, while there were no significant gender differences in terms of cyber-victimization. In terms of participant roles, non-involved students scored higher in Conscientiousness, and cyber-bully/victims in Emotional Instability. The latter also tended to use maladaptive coping strategies more frequently, while cyber-bullies reported using more aggression and resignation to cope with interpersonal conflicts. Multiple regression analyses indicated that low conscientious boys who use passive avoidance and aggression were more likely to cyber-bully, while those who use aggression, passive avoidance and situation control to cope with interpersonal stressors were more likely to be cyber-victimized. Implications of the findings are discussed.

Association between types of involvement in school bullying and different dimensions of anxiety symptoms and the moderating effects of age and gender in Taiwanese adolescents

OBJECTIVE

The aims of this cross-sectional study were to examine the associations of various types of school bullying involvement experiences with different dimensions of anxiety symptoms on the Multidimensional Anxiety Scale for Children (MASC) and to examine the moderating effects of gender and age on the associations in Taiwanese adolescent students aged at 11-18.

METHOD

Involvement in passive and physical bullying and belongings snatch and multiple dimensions of anxiety symptoms in 5537 adolescents were determined through use of the self-reported Chinese version of the School Bullying Experience Questionnaire (C-SBEQ) and the Taiwanese version of the MASC, respectively. The associations between four types of bullying involvement and four dimensions of anxiety symptoms and the moderating effects of gender and age were examined using linear mixed model analysis.

RESULTS

The results indicated that except for the non-significant association between victimization by verbal and relational bullying and harm avoidance, both victims of verbal and relational bullying and physical bullying and belongings snatch reported more severe anxiety symptoms on all four dimensions of MASC-T than non-bullied subjects. While the perpetrators of verbal and relational bullying reported more severe physical symptoms and social anxiety than did non-perpetrators of verbal and relational bullying, the perpetrators of physical bullying and belongings snatch reported less harm avoidance, social anxiety and separation/panic than did non-perpetrators of physical bullying and belongings snatch. Perpetrator-victims of verbal and relational bullying showed more physical symptoms than those who were pure victims or perpetrators of verbal and relational bullying. Perpetrator-victims of physical bullying and belongings snatch had more social anxiety than those who were pure victims or perpetrators. This study also found that gender and age had the moderating effect on the association between some forms of bullying involvement and some dimensions of anxiety symptoms.

CONCLUSIONS

The results of this study support the necessity to apply the multi-dimensional scale to evaluate anxiety symptoms in adolescents who are involved in bullying and to take the different directions of association into consideration when developing prevention and intervention programs.

The association between bullying and the psychological functioning of children with autism spectrum disorders

OBJECTIVE

Bullying has become a major national concern, particularly as it affects children with disabilities. The current study aimed to determine the association between psychiatric comorbid conditions, involvement in bullying (victim, bully, or bully-victim), and the immediate psychological correlates of bullying among children with autism spectrum disorders (ASDs).

METHODS

A national sample of 1221 parents completed a survey dedicated to the bullying and school experiences of their child with ASD, reporting on the immediate consequences of bullying involvement, including their child's psychological well-being and any psychiatric comorbidity. Multivariate logistic regressions were performed to determine whether specific psychiatric comorbidities were associated with an increased risk of involvement as victim, bully, or bully-victim. Analyses of variance determined the relationship between bullying frequency and psychological functioning. All models adjusted for child and school covariates.

RESULTS

Children who were frequently victimized were more likely to present with internalizing symptoms, whereas children who frequently bullied others were more likely to exhibit emotion regulation problems. Children who were identified as frequent bully-victims presented with both internalizing symptoms and emotion regulation problems. Children with attention-deficit hyperactivity disorder (ADHD) and depression were more likely to have been victimized, whereas children with conduct disorder (CD) or oppositional defiant disorder (ODD) were more likely to have bullied other children. Children identified as bully-victims were more likely to have ADHD, CD, or ODD.

CONCLUSIONS

Children with ASDs who had displayed bullying behaviors in the past month exhibited psychological impairments, including psychiatric comorbidity. The frequency of bullying behaviors was significantly associated with the level of impairment.

A review on the relationship between testosterone and life-course persistent antisocial behavior

Life-course persistent antisocial behavior is 10 to 14 times more prevalent in males and it has been suggested that testosterone levels could account for this gender bias. Preliminary studies with measures of fetal testosterone find inconsistent associations with antisocial behavior, especially studies that use the 2D:4D ratio as a proxy for fetal testosterone. However, circulating testosterone consistently shows positive associations with antisocial behaviors throughout childhood, adolescence, and adulthood, particularly in males. It is suggested that high fetal/circulating testosterone interactively influence the maturation and functionality of mesolimbic dopaminergic circuitry, right orbitofrontal cortex, and cortico-subcortical connectivity, resulting in a strong reward motivation, low social sensitivity, and dampened regulation of strong motivational/emotional processes. The link between these testosterone induced endophenotypes and actual display of antisocial behavior is strongly modulated by different social (e.g., social rejection, low SES) and genetic (e.g., MAOA, 5HTT) risk factors that can disturb socio-, psycho-, and biological development and interact with testosterone in shaping behavior. When these additional risk factors are present, the testosterone induced endophenotypes may increase the risk for a chronic antisocial lifestyle. However, behavioral endophenotypes induced by testosterone can also predispose towards socially adaptive traits such as a strong achievement motivation, leadership, fair bargaining behaviors, and social assertiveness. These adaptive traits are more likely to emerge when the high testosterone individual has positive social experiences that promote prosocial behaviors such as strong and secure attachments with his caregivers, affiliation with prosocial peers, and sufficient socioeconomic resources. A theoretical model is presented, various hypotheses are examined, and future venues for research are discussed.

The moderating effect of Machiavellianism on the relationships between bullying, peer acceptance, and school adjustment in adolescents

This study examined the moderating effect of Machiavellianism on the relationships between bullying, peer acceptance, and school adjustment (rule-following behavior and academic performance) among 216 middle school 7th-graders in Taipei, Taiwan. The participants were divided into two groups according to their Machiavellianism. Multi-group path analysis showed that for those who were low in Machiavellianism condition, physical and verbal bullying was negatively linked to peer acceptance and academic performance while no significant association was found for the high-Machiavellianism group. Bullying was negatively, yet non-significantly, associated with rule-following behavior for both groups. The results largely supported the buffering effect of Machiavellianism on the negative outcomes of bullying. Implications for school-violence prevention and for research on adaptive bullies are discussed.
