Bullying victimization among adolescents: Prevalence, associated factors and correlation with mental health outcomes

INTRODUCTION

Knowledge of the risk factors of bullying victimization in adolescents is crucial for the implementation of preventive measures. This study aimed to determine the prevalence and associated factors of bullying victimization and to identify its correlation with mental health outcomes among middle school students in Tunisia.

METHODS

A cross-sectional study was conducted using a multi-stage cluster sampling technique to recruit a sample of 1111 students from 10 middle schools in El kef (Tunisia). The revised Olweus Bully/Victim Questionnaire was used to assess the prevalence and types of bullying victimization and the perceived efforts of others to counteract bullying. The Strengths and Difficulties Questionnaire (SDQ) was used for screening emotional and behavioral problems. Multivariate logistic regression analysis was conducted to determine associated factors of bullying victimization. Additionally, we tested whether emotional and behavioral problems were present for bullying victims.

RESULTS

The findings reported that 45.8% (95%CI = 45.5-46.0), of the total number of participants experienced school bullying victimization. Multivariate logistic regression analysis, revealed that repeating a grade (OR = 1.82, 95%CI = 1.31-2.54), having a working father (OR = 17.68; 95%CI = 2.29-136,15), and having a working mother (OR = 1.88, 95%CI = 1.39-2.53) were the factors significantly associated with bullying victimization. Nevertheless, a higher mother's educational level (OR = 0.76, 95%CI = 0.67-0.88) was a protective factor against bullying victimization. The self-reported SDQ revealed that the total difficulties score was significantly higher among victims (17.46 ± 5.30 vs. 20.86 ± 5.06, p<0.01).

CONCLUSIONS

This study showed that the prevalence of bullying in middle schools was high and it significantly led to mental health problems. National policies for bullying prevention within schools are potentially needed. Improving students' problem-solving and soft skills is also essential.

The effect of parenting styles on adolescent bullying behaviours in China: The mechanism of interpersonal intelligence and intrapersonal intelligence

Bullying is a problematic public behaviour of great concern worldwide, which occurs commonly in China. Parenting and emotional intelligence have previously been verified as crucial aspects in determining the bullying behaviours of adolescents. However, evidence of the interactive effect of these vital factors needs to be more extensive. This study attempts to analyze the relationships and mechanisms of parenting on bullying through emotional intelligence, which consists of interpersonal and intrapersonal intelligence. Based on Chinese education panel survey data of 8730 adolescents, this paper used OLS regression and SEM methods to estimate the impact and mechanisms of parenting styles on bullying behaviours among adolescents. High-demand and responsive parenting styles can significantly reduce adolescents' bullying behaviours. Intrapersonal and interpersonal intelligence are important mediating variables, and parenting with high demandingness and high responsiveness can significantly improve the interpersonal intelligence of adolescents, thereby reducing children's bullying behaviour. Although low levels of intrapersonal intelligence would increase bullying behaviours in adolescents, high demandingness and high responsiveness of parenting can significantly improve adolescents' intrapersonal intelligence. Parents can reduce adolescents' bullying behaviours by increasing emotional responses and normative requirements. This result provides a new perspective on the solution to the problem of youth bullying.

Negative Parenting Style and Perceived Non-Physical Bullying at School: The Mediating Role of Negative Affect Experiences and Coping Styles

At present, school bullying incidents frequently occur, attracting increased attention from researchers. In this study, we attempt to explore the impact of parenting styles on perceived school non-physical bullying. Four hundred ninety-two students in the fifth and sixth grades of eight primary schools in Zhejiang province were surveyed. To control any potential confounding factors, a randomized sampling survey method was used to distribute questionnaires. The results showed that negative affect experiences, negative coping styles, negative family parenting styles, and the perceived school non-physical bullying were all positively correlated with each other (p < 0.05). Perceived verbal bullying differed significantly by gender, grade, and only/non-only children (p < 0.05). Perceived relationship bullying significantly differed between grades (p < 0.05). The gender difference in perceived cyberbullying also reached a significant level (p < 0.05). The rejection parenting style was shown to be an important factor that may be associated with students’ perceived school non-physical bullying; it was observed to be directly associated with students’ perceived school non-physical bullying and indirectly associated with students’ perceived school non-physical bullying by influencing negative affect experiences and negative coping styles. In conclusion, negative affect experiences and coping styles may have a chain-like mediating effect between the rejection parenting style and students’ perceived school verbal bullying. Moreover, negative affect experiences may have a partial mediating effect between the rejection parenting style and students’ perceived school cyberbullying, relationship bullying, and non-physical bullying total scores. This study provides first-hand empirical data support for schools, families, and education authorities to guide and manage non-physical bullying incidents in schools. They also provide a theoretical basis for subsequent related research in the field of non-physical bullying.

Longitudinal Relationship Between Bullying Victimization and Depression Among Left-Behind Children: Roles of Negative Thoughts and Self-Compassion

Background

Left-behind children (LBC) in China have aroused widespread concern in society and the academic field because they have a high risk of psychological problems. For left-behind children, depression is the most serious problem. Bullying victimization has been evidenced as one of the most common causes of children’s depression. However, less is known about its longitudinal association and the process for how bullying victimization influences depression among left-behind children. Thus, the presentation aims to explore the mechanisms underlying by considering the roles of left-behind children’s negative thoughts and self-compassion.

Methods

The 3-wave longitudinal data were collected from a sample of 605 aged 8–11 from central China. We used the Olweus bully and victimization questionnaire, the children’s automatic thoughts scale, the depression scale, and the self-compassion scale.

Results

Bullying victimization positively predicted the depression level of left-behind children. Negative thoughts and self-compassion mediate the relationship between bullying victimization and depression. In the mechanism of bullying victimization on depression exists gender differences among left-behind children.

Conclusion

The present study suggested the association between bullying victimization and left-behind children’s depression and revealed the internal mechanism of negative thoughts and self-compassion. These findings provide a new perspective for left-behind children’s mental health education and intervention.

Self-Efficacy and External Locus of Control as Predictors of Participant Roles in Relational Aggression

We examined the extent to which the perceived behavioral control factors of pro-social, emotional, or verbal-social self-efficacy (SE) as well as external locus of control (LOC) explain the variance between different participant roles: relational aggressors, relational victims, relational aggressive-victims, and bystanders. Participants included 1,518 adolescents (61.6% boys and 38.4% girls) from 15 Israeli middle and high schools. Multinomial logistic regression models indicated relational aggressors, and aggressive-victims had lower pro-social SE and higher verbal-social SE than relational victims and bystanders. Relational aggressors, aggressive-victims, and victims had more extensive external LOC than bystanders. The theoretical contribution of verbal-social SE is discussed, and practical implications are highlighted, in particular, regarding the relational aggressive-victim, who exhibits high-risk behaviors.

Bullying and coping with bullying among obese\overweight and normal weight children

This study aimed to determine the obese\overweight and normal weight children's status of encountering and coping with bullying and the correlational factors. This case-control study was conducted with 1.680 students in the second level (5th, 6th, 7th, 8th grades) from September 24, 2018 to May 31, 2019 in the Mediterranean Region in Turkey. The data were collected using a personal information form, the Traditional Peer Victimization Scale and the Coping with Bullying Scale. Data were analyzed using the Shapiro-Wilk test, Mann-Whitney U test, Binary Logistic Regression, Backward Wald Elimination, and Simple Linear and Backward Stepwise Multiple Linear Regression analyses. This study indicated that the risk of becoming victims, bullies or bully-victims increases among boys and 8th grade students. It also found that the risk of being victims and bully-victims increases among children whose father is illiterate. There was no significant difference between obese\overweight and normal weight children in terms of being victims, bullies and bully-victims. Grade level, academic performance, father's education level and awareness of reporting bullying were effective in coping with bullying among the children, while weight was not. Further studies are needed to determine different factors that affect children's coping strategies against bullying.

Childhood trauma and cognitive biases associated with psychosis: A systematic review and meta-analysis

Childhood trauma is associated with an increased risk of psychosis, but the mechanisms that mediate this relationship are unknown. Exposure to trauma has been hypothesised to lead to cognitive biases that might have causal effects on psychotic symptoms. The literature on whether childhood trauma is associated with psychosis-related cognitive biases has not been comprehensively reviewed. A systematic review and meta-analysis or narrative synthesis of studies examining the association between childhood trauma and the following biases: external locus of control (LOC), external attribution, probabilistic reasoning, source monitoring, top-down processing, and bias against disconfirmatory evidence. Studies were assessed for quality, and sources of heterogeneity were explored. We included 25 studies from 3,465 studies identified. Individuals exposed to childhood trauma reported a more external LOC (14 studies: SMD Median = 0.40, Interquartile range 0.07 to 0.52), consistent with a narrative synthesis of 11 other studies of LOC. There was substantial heterogeneity in the meta-analysis (I2 = 93%) not explained by study characteristics examined. Narrative syntheses for other biases showed weaker, or no evidence of association with trauma. The quality of included studies was generally low. Our review provides some evidence of an association between childhood trauma and a more external LOC, but not with the other biases examined. The low quality and paucity of studies for most of the cognitive biases examined highlights the need for more rigorous studies to determine which biases occur after trauma, and whether they mediate an effect of childhood trauma on psychosis.

The Impact of Parental Factors on Physical Aggression Perpetration among Turkish Urban Adolescents: The Mediating Role of Beliefs Supporting Aggression

This study investigated parental factors and beliefs supporting aggression as predictors of physical aggression by adolescents. The participants were 2,443 junior high school students from Ankara, Turkey, who completed measures of parental support for aggression, family conflict, parental monitoring, beliefs supporting aggression, and physical aggression. The findings showed both direct and indirect effects of parental factors on physical aggression through beliefs supporting aggression. Furthermore, a multigroup model comparison indicated invariance of the structural relationships among variables in the model across gender and that the hypothesized structural model was a close fit for both the girl and the boy data. The findings suggest that it might be beneficial to consider beliefs supporting aggression and parental factors as risk factors when designing interventions to target physical aggression among adolescents.

Bullying Perpetration, Victimization, and Low Self-esteem: Examining Their Relationship Over Time

Bullying experiences in adolescents could cause maladjusted developments like low self-esteem, which in turn could increase the likelihood of having bullying experiences. Examining these longitudinal reciprocal relationships by considering the co-occurrence of bullying experience is critical, but under-examined. The current study clarifies the longitudinal reciprocal relationship between adolescents' bullying perpetration, victimization, and low self-esteem. An autoregressive cross-lagged model was analyzed with data collected from 3658 Korean secondary students (47.2% were females, Mean age = 12.07, standard deviation = 0.27, range = 11-14) from the Seoul Education Longitudinal study in three waves (seventh to ninth grades). After controlling prior bullying perpetration, victimization, and low self-esteem, low self-esteem positively predicted subsequent victimization, and victimization also positively predicted subsequent low self-esteem longitudinally. However, low self-esteem failed to predict subsequent bullying perpetration, which in turn, failed to predict subsequent low self-esteem. After the prior bullying experiences and low self-esteem are controlled, their longitudinal association becomes clearly distinct. Victims of bullying may fall into a vicious circle, where after being victimized, they themselves feel unlovable or incompetent, and their increased low self-esteem is linked to subsequent victimization. To break out of this vicious circle and temporal stability of victimization, interventions focusing on victims' self-esteem would be effective.

Undesirable social relations as risk factors for loneliness among 14-year-olds in the UK: Findings from the Millennium Cohort Study

In the current study, data collected from Wave 6 of the Millennium Cohort Study ( n = 11,872), a nationally representative sample survey of youth aged 14 years in the UK, are used to examine the prevalence of loneliness among this age-group, investigate the feelings associated with the experience of loneliness among youth, explore the risk factors for loneliness among young people, and learn how they coped with loneliness. Given recent findings that youth are vulnerable to loneliness, the study assesses the prevalence of loneliness among adolescents across some important sociodemographic characteristics, such as nation of residence, gender, and ethnicity. We also identify the kinds of social experiences that accompany loneliness during adolescence, exploring friendship, relations with parents, social support, and bullying. Our key finding is that, in addition to the absence of desired social relationships, which has been typically identified as the ultimate source of loneliness, the presence of undesirable and even harmful social relationships is a major source of loneliness. This study uniquely brings together psychological and sociological perspectives to understand the experience of youth loneliness.

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.

Risk and Protective Factors for Bullying at 11 Years of Age in a Spanish Birth Cohort Study

(1) Background: Bullying affects a large number of children worldwide. This study has two objectives, to provide data on the prevalence of bullying in Spain, and to identify risk and protective factors associated with bullying. (2) Methods: Participants were 858 eleven-year-old children. Bullying was assessed using a short version of the Olweus Bully Victim Questionnaire, and the following data were gathered to explore potential predictors: individual (inattention, behavior problems, attention deficit hyperactivity disorder symptomatology, traumatic life events), family-related (sociodemographic characteristics, family context, child-parent relations), school-related (school characteristics, peer and social support, school environment) and community-related data. (3) Results: 9.3% of the children were victims, 1.4% bullies and 1.6% bully-victims. Results showed that a higher level of attention deficit hyperactivity disorder symptomatology increased the risk of victimization, whereas having better relationships with parents and stronger social support were associated with a lower risk of victimization. Children having strong peer relationships and social support was also associated with less risk of perpetrating bullying. Finally, having behavior problems at 8 years of age was associated with being a bully-victim. (4) Conclusions: The findings emphasize the importance of studying all bullying predictors together, regarding three of the roles children may take in bullying situations.

Powerful and confident children through expansive body postures? A preregistered study of fourth graders

Do expansive body postures increase self-esteem in children? Power posing is a popular but also controversial topic. Still, there has been no research on the possible effects in children. To investigate the influence of power posing in children, 108 German fourth graders were randomly assigned to a high versus a low power posing group. Self-esteem was self-reported; feelings were assessed indirectly. There was an effect of power posing on self-reported global and school self-esteem. Furthermore, children who had performed high power poses in comparison with those who had performed low power poses mentioned more positive feelings, higher power feelings, and a more positive student–teacher relationship. Results are interpreted with regard to the context and the cultural dependency of the power posing effect. Implications for school practice are addressed.

Using a Mixed-Methods Approach to Analyze Traumatic Experiences and Factors of Vulnerability Among Adolescent Victims of Bullying

A number of studies have analyzed the bullying phenomenon among adolescent victims. Relatively few studies, however, have specifically addressed the associated post-traumatic stress disorder (PTSD). Our clinical practice and therapeutic encounters with adolescents reveal that the majority of bullied adolescents suffer from high levels of PTSD. The objective of this study is to further explore bullied adolescents' traumatic experiences. In an attempt to analyze these experiences, this article presents a mixed-methods approach. Such an approach will allow to analyze the PTSD that results from bullying as well as subjects' psychic and family-relevant vulnerabilities. First, bullying will be defined in the context of adolescence. Then the main studies on bullying will be presented. The objectives, tools and methods of analysis will be presented. The interviews will be analyzed according to the Interpretative Phenomenological Analysis (IPA) method. Projective tools, family drawings, Rorschach and Thematic Apperception Test (TAT), will be analyzed using a psychoanalytic interpretation method. Each qualitative tool will be used alongside a validated quantitative tool. The Clinical Administered PTSD Scale (CAPS-CA-5 questionnaire) and the interviews conducted will thus allow to analyze PTSD and traumatic experiences. The Family Assessment Device (FAD) and the family drawing test will enable to assess family functioning; lastly, the Symptom Check List (SCL-90) that will be used alongside Rorschach and TAT tests will allow to analyze individual psychological vulnerabilities. This approach will increase data validity. The originality of this research study is based on a mixed-methods approach, our methodology which is based on clinical psychology, and the choice of certain research tools which have received little attention to date. Ultimately, this study may help improve how bullying is identified and could contribute toward the reinforcement or revision of the criteria that characterize bullying. Lastly, it may help us explore various unexamined dimensions of bullying. A possible limitation is the complexity associated with such a protocol.

The Predictive Role of Maternal Parenting and Stress on Pupils' Bullying involvement

The link between inappropriate parenting style and both bullying and victimization is well documented. However, it is not clear as to which kind of parenting style is associated with victimization. Furthermore, no studies have yet been conducted regarding the role of parental stress in bullying and victimization. This study aimed to examine the role of parenting styles and maternal stress in pupils' bullying and victimization. A total of 300 primary school pupils, enrolled in fourth and fifth grades, participated in the study. Initially, 100 noninvolved pupils were randomly selected using a multistage cluster sampling method. Then using a screening method, 100 bully pupils and 100 victimized peers were selected. Olweus Bullying Scale and teacher nomination were administered for screening these pupils. Baumrind Parenting Style Questionnaire and revised version of Abidin Parental Stress Index (short form) were also applied to all pupils in the study. Data were analyzed using discriminant function analysis. The findings showed that (a) with regard to parenting styles, significant differences were found among groups. Authoritarian parenting style could significantly predict pupils' bullying behavior, whereas victimization was predictable in families with permissive parenting style. In addition, noninvolved pupils were predicted to have authoritative parenting style. (b) Considering maternal stress, significant differences were observed across groups. Parents of bullies and victims were predicted to have higher maternal stress than noninvolved pupils. The implications of the study in relation to the role of mothers in bullying and victimization are discussed.

Self-Perceptions and Factors Associated With Being Put Down at School Among Middle and High School Students

This study assessed the prevalence of verbally being put down by others and intrapersonal and normative factors associated with being put down by others among middle and high school students. Students (N = 1,027) completed the Adolescent Health Risk Behavior Survey. Over 16% of participants reported being put down at school. Students who identified with the negative words confused, unattractive, dull, and careless and identified less with the positive words popular, smart, considerate, cool, and self-confident reported being put down by others. High school students were less likely to be put down. As students scored higher on the Negative Self-Description Scale, their odds of being put down increased. As students scored higher on the Positive Self-Description Scale, their odds of being put down decreased. Students who perceived their friends drinking alcohol regularly were less likely to be put down. Strategies to enhance self-perceptions to raise self-awareness and form healthy/positive identities are needed.

Adolescent characteristics and parenting style as the determinant factors of bullying in Indonesia: a cross-sectional study

BACKGROUND

The incidence of adolescents bullying in Indonesia has increased. The purpose of this study was to analyze the correlation of demographic characteristics, parental interactions and parenting style as the potential determinants of bullying behavior in adolescents.

METHOD

The research design used was cross-sectional. The study population consisted of adolescents in Indonesia who accessed the Google form, and adolescents who study at a junior high school and a vocational high school in Surabaya. The study sample totaled 705 adolescents based on consecutive sampling with a study period of 3 months. The independent variables were demographic characteristics, parental interactions and parenting style, while the dependent variable was bullying behavior. The data collection method used was a questionnaire filled in by the adolescents through a Google form and a questionnaire sheet. The statistical analysis used the chi-square test for the adolescent's characteristics and Spearman's rank correlation with α = 0.05.

RESULTS

The results showed that the characteristics of the adolescents, namely age and place of residence, were related to bullying behavior. A permissive and authoritarian parenting style had a positive correlation with being a bullying perpetrator, while only permissive parenting style had a positive correlation with being a bullying victim.

CONCLUSION

Adolescents experience bullying behavior as both the perpetrators and victims. Adolescents living in rural areas are more likely to commit bullying as the perpetrators. A parenting style that is either too rigid or too free has a high risk of being a bullying behavior factor as the perpetrator. Parents are expected to apply an authoritative parenting style in order to prevent the risk of bullying in adolescents.

Parenting Style and Reactive and Proactive Adolescent Violence: Evidence from Spain

The aim of the present study was to analyze the relationship between the parenting styles—authoritative, indulgent, authoritarian, and neglectful—and reactive and proactive school violence among peers. These analyses were also performed by sex and age groups. The sample consisted of 2399 Spanish adolescents (50.2% male), aged between 12 and 18 years, mean (M) = 14.69, standard deviation (SD) = 1.82. A multivariate analisys of variance (MANOVA, 4 × 2 × 2) was applied, considering parenting style, sex, and age group (12–14 and 15–18 years) as independent variables to analyze the possible effects of interaction. Reactive, proactive, and pure violence were the dependent variables. The results showed the main effects of parenting styles, sex, and age, as well as an interaction between sex, age, and parenting styles. The interpretation of the findings suggested that the authoritarian parenting style was related to greater engagement in proactive and reactive violent behaviors. In relation to the effect of the interaction between sex, age, and parenting styles, it was observed that adolescents from indulgent families, of both sexes and in any of the studied age groups, obtained lower scores in proactive violence. The discussion highlights the importance of affection and warmth for well-adjusted children’s behavior.

The Mediating Effect of Regulatory Emotional Self-Efficacy on the Association between Self-Esteem and School Bullying in Middle School Students: A Cross-Sectional Study

School bullying is negatively associated with self-esteem, but psychological mediators of bullying have yet to be clarified. We examined regulatory emotional self-efficacy (RESE) as a possible mediator in the association between self-esteem and school bullying. A cross-sectional study of 995 adolescents was conducted in two middle schools of Xi'an. All of the participants completed the Chinese version of the School Bullying Experience Questionnaire (C-SBEQ), Self-Esteem Scale (SES), and Regulatory Emotional Self-Efficacy Scale (RESE). Descriptive statistics analysis, the bias corrected percentile Bootstrap CI method, and structural equation modelling were used to analyze the data. The results showed that 418 students (42.0%) reported that they were involved in school bullying in the past year. Self-esteem was negatively associated with school bullying (total effect: β = -0.275, 95% CI = -0.381⁻-0.034), and RESE mediated the association between self-esteem and school bullying (indirect effect: β = -0.136, 95% CI = -0.245⁻-0.037). Furthermore, self-esteem had an indirect effect through perceived self-efficacy in managing negative affect, while self-esteem had no indirect effect through self-efficacy in the expression of positive affect. The present study suggests that school authorities and the related education departments should not only focus on improving students' self-esteem, but should also pay more attention to students' RESE, in order to mitigate, and potentially reduce, the occurrence of bullying.

Factors Affecting Jordanian School Adolescents' Experience of Being Bullied

PURPOSE

The purpose of this study was to identify the Jordanian school adolescents' experience of being bullied, and to examine its association with selected socio-demographic variables.

DESIGN AND METHODS

This cross sectional descriptive study used multi-stages cluster sampling technique to recruit a sample of in-school adolescents in Jordan (N=436). The Personal Experiences Checklist was used to measure the experience of bullying. Descriptive statistics and parametric tests were used in the analysis.

RESULTS

Relational-verbal bullying was the most common form of bullying while cyber bullying was the least common type. Male adolescents experienced bullying more than females. In addition, adolescents belonging to low-income families experienced bullying more than those from moderate-income families. Finally, being bullied was negatively correlated with academic performance of students.

CONCLUSIONS

This study indicated that risk factors for bullying are multifaceted which necessitate the development of prevention and intervention strategies to combat bullying taking into consideration these factors.

PRACTICE IMPLICATIONS

Schools should introduce environmental changes to discourage bullying and establish a policy with specific guidelines of what constitutes bullying behavior and expected disciplinary procedures. Staff training on information about the definition of bullying, current trends, and the effects of bullying is also recommended.

Bullying and Victimization: The Effect of Close Companionship

Peer bullying and victimization are a widespread phenomenon among school-age children and can have detrimental effects on the development of children. To examine whether having a close companion during childhood increases or decreases risk of victimization and bullying, this study compared twins to singleton children. A large group of twins (n = 9,909) were included who were compared to their related non-twin siblings (n = 1,534) aged 7-12 from the Netherlands Twin Register, thus creating optimal matching between twins and non-twins. Bullying and victimization were each based on a four-item scale filled out by their teachers. Prevalence rates for either bullying or victimization did not differ between twins and singletons. In total, in the past couple of months, 36% of children bullied peers moderately to severely, and 35% suffered moderately to severely from victimization. Boys were more likely to bully and were more prone to becoming a victim than girls. The most notable finding is that female twin pairs placed together in the same classroom did not bully more often, but were victimized less often, thus pointing to a protective effect of having a close companion in the classroom.

Bullying and Peer Victimization: An Examination of Cognitive and Psychosocial Constructs

Research has demonstrated a link between internalizing factors and bullying perpetration and peer victimization; however, few studies have examined predictors of cognitive and psychosocial factors, such as locus of control and hopelessness. The current study examined cognitive and psychosocial factors in bullying perpetration and peer victimization in a sample of 469 middle school students. A mediator model of hopelessness was also investigated. Students involved in bullying reported a greater external locus of control compared with peers who were not involved in bullying. Bully-victims endorsed the highest externality. Results showed that hopelessness fully mediated the relationship between verbal/relational victimization and external locus of control for the victim group, but not the bully-victim group. Implications for bullying prevention and intervention efforts are discussed.

Examining explanations for the link between bullying perpetration and physical dating violence perpetration: Do they vary by bullying victimization?

This short-term longitudinal study examined whether the association between bullying perpetration and later physical dating violence perpetration and mediators of that association (via anger, depression, anxiety, and social status), varied depending on level of bullying victimization. Differences have been noted between those who bully but are not victims of bullying, and those who are both bullies and victims. These differences may influence dating violence risk and the explanations for why bullying leads to dating violence. Data were from dating adolescents in three rural counties who completed self-administered questionnaires in the fall semester of grades 8-10 and again in the spring semester. The sample (N = 2,414) was 44.08% male and 61.31% white. Bullying perpetration in the fall semester predicted physical dating violence perpetration in the spring semester when there was no bullying victimization, but not when there was any bullying victimization. Bullying perpetration was positively associated with anger at all levels of bullying victimization and with social status when there was no or low amounts of victimization; it was negatively associated with social status at high levels of victimization. Bullying victimization was positively associated with anger, depression, and anxiety at all levels of bullying perpetration. Anger mediated the association between bullying perpetration and dating violence, regardless of level of victimization; depression, anxiety, and social status did not mediate the association at any level of bullying victimization. The findings have implications for dating violence prevention efforts and for future research on the link between bullying and dating violence.
