RESUMO
OBJECTIVE: Resource deprivation is linked to systemic factors that disproportionately impact historically marginalized communities, and theoretical work suggests that resource deprivation may increase risk for bullying behaviors. Bullying perpetration is an intransigent social problem and an early risk factor that perpetuates the school-to-prison pipeline. This study explored how resource deprivation (family- and neighborhood-level metrics) was associated with early childhood bullying behaviors and clinician-rated symptoms of psychopathology, while accounting for other known risk factors (early life stressors, traumatic events, parental arrest, domestic violence). METHOD: Participants (306 children, mean age = 4.45 years) were enrolled in a longitudinal study (Preschool Depression Study) where demographics, clinician-rated assessments of psychopathology, and parent reports of social functioning were collected. Measures of bullying behaviors (bullying perpetration, generalized aggression, and victimization) were constructed. A cross-sectional approach was employed, and analyses examined the interrelations between race, bullying-related behaviors, resource deprivation, and psychopathology, while accounting for confounding variables, at the baseline assessment time point. RESULTS: The bullying measure showed acceptable model fit (comparative fit index = 0.956, Tucker-Lewis index = 0.945, root mean square error of approximation = 0.061, standardized root mean residual = 0.052, normed χ2 ratio = 2). Neighborhood resource deprivation was more strongly associated with bullying perpetration (r = 0.324, p < .001) than generalized aggression (r = 0.236, Williams t303 = 2.11, p = .036) and remained significant when controlling for other known risk factors (parental arrests, domestic violence, stressors, traumas) and demographic factors. Bullying perpetration was linked with racial category, but the relation was fully mediated by neighborhood resource deprivation. Linear regression including bullying behaviors and symptoms of clinical psychopathology suggested that resource deprivation specifically led to increases in bullying perpetration (t = 2.831, p = .005) and clinician-rated symptoms of conduct disorder (t = 2.827, p = .005), which were attributable to increased rates of resource-driven conduct symptoms (bullies, lies to obtain goods, stolen without confrontation). CONCLUSION: Resource deprivation is strongly and specifically associated with increases in bullying perpetration. Children growing up in impoverished neighborhoods show significant increases in resource-driven conduct behaviors, yet interventions often target individual-level factors. These results highlight the need to target social inequity to reduce bullying perpetration and suggest that interventions targeting neighborhoods should be tested to reduce bullying in early childhood.

RESUMO
BACKGROUND: The National Academy of Sciences has recognized bullying as a serious public health issue, with the outcomes of bullying immediate and long-term. The purpose of this study was to examine the relationship between 7 selected positive childhood experiences, such as having a mentor, and bullying victimization, and bullying perpetration. METHODS: We used cross sectional data from the 2019-2020 National Survey of Children's Health, children ages 6 to 17 (n = 43,999). Bivariate analyses were used, with p < .05 deemed significant. To examine the association between experiences and bullying victimization or perpetration, multivariable regression models were used. RESULTS: Children who experienced any of the following positive childhood experiences had a lower odds of perpetration of bullying victimization: resilient family; safe neighborhood; supportive neighborhood; or connected caregiver. The following covariates had a lower odds of perpetrating bullying, across all models: race other than white, female sex, age of 13 or older, primary language not English, and a guardian education of a high school diploma or less. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Schools can play a formative role in promoting positive childhood experiences identified herein. CONCLUSIONS: Findings from this study may be beneficial for educators, policy makers, and child advocacy stakeholders as they design and implement school or community-based youth development programs.

Despite the extensive literature on the psychosocial determinants of bullying and cyberbullying among adolescents, there is not sufficient comprehensive analysis of the differences between perpetrators. This study aims to assess the psychosocial similarities and differences between bullies and cyberbullies. Data of 3650 students from two grades, K9 and K11 (47% females, mean age = 16.53), were used from a survey conducted in Poland in 2018 as part of the Health Behaviour in School-aged Children study. Perpetration was measured by questions adapted from the Olweus Bully/Victim Questionnaire. The following predictors were analyzed: demographic, socioeconomic status measured with the Family Affluence Scale-III (FAS), and individual and social factors. Multiple binary logistic regression was applied. The random sampling design was based on stratification according to the local deprivation index of the region where the school was located. Male gender, younger age, and non-intact family were associated with a higher risk of bullying and cyberbullying. Family support, empathy, school performance, and school attachment had a protective effect against both aggressive behaviors. Life dissatisfaction and high FAS were revealed as determinants of cyberbullying and local deprivation of bullying only. Bullying and cyberbullying school prevention programs should take into account these psychosocial differences and consider the economic deprivation of the region.

PURPOSE: Social patterns in bullying show consistent gender differences in adolescent perpetration and victimization with large cross-national variations. Previous research shows associations between societal gender inequality and gender differences in some violent behaviors in adolescents. Therefore, there is a need to go beyond individual associations and use a more social ecological perspective when examining gender differences in bullying behaviors. The aim of the present study was twofold: (1) to explore cross-national gender differences in bullying behaviors and (2) to examine whether national-level gender inequality relates to gender differences in adolescent bullying behaviors. METHODS: Traditional bullying and cyberbullying were measured in 11-year-olds to 15-year-olds in the 2017/18 Health Behaviour in School-aged Children study (n = 200,423). We linked individual data to national gender inequality (Gender Inequality Index, 2018) in 46 countries and tested their association using mixed-effects (multilevel) logistic regression models. RESULTS: Large cross-national variations were observed in gender differences in bullying. Boys had higher odds of perpetrating both traditional and cyberbullying and victimization by traditional bullying than girls. Greater gender inequality at country level was associated with heightened gender differences in traditional bullying. In contrast, lower gender inequality was associated with larger gender differences for cyber victimization. DISCUSSION: Societal gender inequality relates to adolescents' involvement in bullying and gendered patterns in bullying. Public health policy should target societal factors that have an impact on young people's behavior.

Although job-related work environment studies found associations to workplace bullying perpetration, little work with longitudinal designs has been conducted on broader organizational measures, which may help design effective interventions for perpetration. Using a three-wave longitudinal design and drawing on Conservation of Resources Theory, we investigated whether organizational trust and justice predicted perpetration six months later. The sample consisted of 2447 employees from Spain and Turkey from various industries, such as services, manufacturing, and education. We also investigated whether physical and psychological health explained the relationship between organizational trust, justice, and perpetration. The results indicated that, in three months, organizational justice negatively predicted psychological and physical health deterioration, while unexpectedly, organizational trust positively predicted the same. Health conditions did not predict perpetration, in three months, while organizational conditions did not predict perpetration directly or indirectly in six months. Assessing and improving organizational trust and justice practices may help employee health improve over time. As organizational trust, justice, and health status are significantly related to current perpetration incidents, assessments of these subjects may be instrumental in identifying possible current perpetration phenomena.

Previous research indicates that the disproportionate distribution of income within society is associated with aggression and violence. Although research has been conducted identifying the relationship between income inequality and bullying victimization and perpetration, little is known about possible mediators. We investigated the association between income inequality and bullying perpetration and victimization among adolescents participating in the Cannabis, Obesity, Mental health, Physical activity, Alcohol use, Smoking, and Sedentary behavior (COMPASS) study. We identified whether school connectedness and psychosocial well-being mediated the relationship between income inequality and bullying behavior. This study used pooled cross-sectional data from 147,748 adolescents aged 13 to 18 from three waves (2015-2016, 2016-2017, 2017-2018) of the COMPASS study from 157 secondary schools in British Columbia, Alberta, Ontario, and Quebec (Canada). The Gini coefficient was calculated based on the school Census Divisions (CD) using the Canada 2016 Census and linked with student data. We used multilevel modeling to investigate the relationship between income inequality and self-reported bullying victimization and perpetration, while controlling for individual-, school-, and CD-level characteristics. A standard deviation increase in Gini coefficient was associated with increased odds for bullying victimization and perpetration. Findings were observed among girls; however, inequality was only associated with perpetration among boys. We identified social cohesion and psychosocial well-being as potential mediators. To counter the adverse effects of income inequality, school-based interventions designed to increase school connectedness and student psychosocial well-being should be implemented to protect against bullying.

Despite putative gender differences in the expression of narcissism, prominent theories have virtually dismissed the role of females in the development and manifestation of narcissism. The contention that narcissism is a pathology of the self that may partly differ in males and females is further evident in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 reports that up to 75% of those diagnosed with Narcissistic Personality Disorder (NPD) are men. Such figures suggest that the representation of narcissism as codified in the DSM-5 may only be marginally applicable to females, given its prominent focus and nature on capturing grandiose themes which closely resemble commonly masculine norms. The overemphasis on grandiose features extends to the empirical literature which defines narcissism as a normative personality trait and is widely assessed using the Narcissistic Personality Inventory (NPI), on which males obtain significantly higher scores than females. As this review will demonstrate, one limitation frequently occurring in the literature is the attempt to comprehend narcissistic manifestations in females through the lens of what has commonly been defined as narcissism (DSM/NPI). In this review, the literature concerning the diagnostic assessment and conceptualisation of narcissistic personality disorder, aetiological factors, aggression, and partner violence perpetration will be discussed in relation to the importance of gender. This is followed by a review of existing gaps in theory and research, and suggestions for fruitful directions that can aid a richer and more meaningful literature on narcissism inclusive of gender issues.

University-based sexual aggression is an international public health issue; however, to date, there have been no formal assessments of the prevalence or psychological indicators associated with the proabuse behaviors of the most common perpetrators at UK universities: heterosexual male students. To facilitate the development of effective primary prevention interventions for domestic students who have sexually harmed, we assess across two empirical studies (Ns = 259 and 295) the psychological risk factors associated with recent sexual aggression amongst two distinct samples of UK male university students. Cumulatively, results highlighted that one in nine participants (11.4%) self-reported recent sexual aggression. These participants could be statistically differentiated from their non-offending peers on various established indicators of general sexual offending, of which logistic regression analyses highlighted atypical sexual fantasies, general aggression, hostility toward women, and rape myth acceptance as being the most reliable predictors. Our data extend the international evidence base by providing the first detailed overview of sexual aggression amongst UK male university students, as well as the psychological risk factors associated with their proabuse behaviors. We discuss the importance of our findings for the development of more effective evidence-based reduction strategies and primary prevention interventions for male students who have sexually harmed.

The occurrence of aggressive behavior in intimate relationships carries serious mental and physical health consequences for the victims and children exposed to such events. Studies have been devoted toward understanding the nature and prevalence of the phenomenon; however, there has been a paucity of empirical investigation into the complexities and nuances of the subject matter, and this study seeks to address one of such complexities. This study examines the dynamics of intimate partner violence (IPV) within the context of perpetration and victimization among residents in Bariga Local Community Development Area in Lagos State, Nigeria. Using a cross-sectional survey, 218 married residents of the area were analyzed through bivariate and multivariate regression analysis. The results of the study revealed that gender and socioeconomic factors were not associated with IPV victimization. Educational differences between the respondent and spouse were associated with IPV victimization. Individuals who perpetrated IPV were about 19 times more likely to experience IPV. This study sheds light on the areas of IPV that tend to be ignored in academic literature and it calls for more empirical investigation, both at the quantitative and qualitative levels, to be conducted for better understanding of the subject matter.

Objective: There are concerns about the measurement of teen dating violence (TDV) perpetration. The current study compares data on TDV perpetration derived from a cumulative assessment procedure and a single assessment procedure. The prevalence and frequency of TDV perpetration are examined, as well as their associations with hypothesized precursors of TDV. Method: A sample of court-referred adolescents (n = 147, Mage = 15.85) completed a baseline assessment that included measures of three hypothesized precursors to TDV: externalizing problems, exposure to community violence, and attitudes about dating violence. For the cumulative assessment procedure, adolescents then completed up to 6 phone interviews on their TDV perpetration (physical, sexual, and emotional), once every 2 weeks over the course of a 3-month period. Data from these interviews were aggregated to form a cumulative measure of TDV perpetration over the 3 months. For the single assessment procedure, adolescents completed an identical interview on their TDV perpetration in a lab assessment 3 months after baseline, but were asked about perpetration over the entire 3 months. Results: Results of within-subjects comparisons indicated that, compared to the single assessment procedure, the cumulative assessment procedure yielded higher prevalence and greater frequency of physical, sexual, and emotional TDV. Across analytic methods, all types of TDV perpetration were more strongly related to externalizing problems, and sexual TDV perpetration was more strongly related to exposure to community violence, when measured cumulatively. Conclusions: Cumulative assessment procedures might provide a more sensitive and valid measurement of TDV perpetration than single assessment procedures.
RESUMO
Three dopamine genes (DAT1, DRD2, and DRD4) have been associated with interpersonal delinquency, aggression, and violence when individuals experience adverse environmental exposures. Guided by the catalyst model of aggression, risk alleles identified in previous studies were hypothesized to be associated with intimate partner violence (IPV) perpetration in the presence of financial stressors, a possible environmental trigger. This hypothesis was tested using weighted, clustered logistic regression with data from the National Longitudinal Study of Adolescent to Adult Health. The direct effects DAT1, DRD2, and DRD4 on IPV perpetration, and the interaction of DAT1, DRD2, and DRD4 and financial stressors on IPV perpetration were assessed. Due to cell size, only White men and women were included in this analysis. Increasing number of financial stressors was associated with increased odds of IPV perpetration, regardless of DAT1, DRD2, and DRD4 alleles. As predicted, increasing number of financial stressors was more strongly associated with IPV perpetration among individuals with high-risk DAT1 alleles, than individuals with low-risk alleles. However, this relationship was inverted for DRD2. Although there was still a significant interaction between DRD2 and financial stressors, individuals with low-risk alleles had higher odds of IPV perpetration in the presence of financial stressors. A similar, nonsignificant relationship was found for DRD4. These findings indicate that these genes may interact differently with environmental exposures and types of violent behavior. In addition, the findings may, if replicated, suggest dopamine plays a different role in IPV perpetration compared with other forms of aggression and violence.

Patterns of-and correlates associated with-bullying perpetration and peer victimization have received widespread research attention. Somewhat less research has considered how protective factors in the parental domain help to buffer against both adverse behaviors. And perhaps more importantly, even less research has considered potential racial differences in the manner in which family-level variables relate to both bullying perpetration and peer victimization. Using a nationwide sample of adolescents, the present study examines (a) how parent/guardian support, mother's parental monitoring, father's parental monitoring, and family satisfaction buffer against bullying perpetration and peer victimization; and (b) whether these relationships vary across race. Data are derived from the 2009 to 2010 Health Behavior in School-Aged Children study in the United States. A total of 8,998 adolescents were included in the study sample, which consisted of 6,521 European Americans and 2,477 African Americans. Findings show that both European American and African American youth who received parental/guardian support were less likely to report being bullied. Among both African American and European American sub-samples, results showed that mother's parental monitoring was negatively associated with both bullying perpetration and peer victimization. Father's parental monitoring was negatively associated with peer victimization and bullying perpetration for European Americans only. Both European and African American youth who reported being satisfied with their family were less likely to report being bullied while European American youth who reported higher family satisfaction were less likely to engage in bullying. In sum, several family variables help to buffer against both bullying perpetration and peer victimization, but for the most part these relationships are race-invariant.

A unique form of sexual victimization that often goes undiscussed and, therefore, underassessed is that of being forced to penetrate another person (i.e., forced penetration). Due to forced penetration being a relatively novel addition to the definition of rape, there is a lack of assessment tools that identify forced penetration cases. Thus, the goal of this study was to assess the utility and validity of new items designed to assess forced penetration. More than 1,000 participants were recruited across three different studies to assess forced penetration victimization and perpetration. The rate of forced penetration victimization ranged from 4.51% to 10.62%. Among men who reported victimization of any type, 33.8% to 58.7% of victimized men reported experiencing forced penetration across the samples, suggesting this experience is common. All new and unique cases of sexual victimization identified by the forced penetration items were those of heterosexual men. These findings suggest that assessing for forced penetration would increase the reported prevalence rates of sexual victimization, particularly in heterosexual men (and correspondingly, rates of perpetration in women).
RESUMO
This article explores the ways poly-victimized youth (those experiencing multiple different types of victimization over the course of 1 year) use technology to interact with peers. Particular attention is given to the peer harassment victimization and perpetration experiences of poly-victimized youth compared with less victimized and non-victimized youth-both overall and through technology. Data were collected as part of the Technology Harassment Victimization (THV) study; a national survey of 791 youth, ages 10 to 20 across the United States. Study results document the heightened risks that poly-victimized youth experience when interacting with peers. Low and high poly-victimized youth were both at significantly greater risk of being dual victims and perpetrators of peer harassment when compared with non-victimized youth even after taking into account other potentially explanatory factors. This was not found to be the case for less victimized youth. This was true for high poly-victims and technology-involved harassment risk as well. There were indications that poly-victimized youth were interacting with peers in more intense and risky ways in general using new technology. The increase in attention to poly-victimization in recent years has importantly identified the detrimental role that experiencing different forms of victimization have on youth. This study not only adds to that literature but suggests that there is an opportunity to interrupt additional victimization by understanding how poly-victimized youth interact with peers before and during adolescence. Although preliminary, the differences in technology use by poly-victimized youth versus others suggest that more information is needed to understand how they are relating to peers in both positive and risky ways in this environment.

BACKGROUND: Violence against women is driven by gender norms that normalize and justify gender inequality and violence. Gender norms are substantially shaped during adolescence. Programs offered through schools offer an opportunity to influence gender attitudes toward gender equity if we understand these to be partly shaped by peers and the school environment. OBJECTIVE: We present an analysis of the baseline research conducted for a randomized controlled trial with 1752 grade 6 boys and girls and their attitudes toward gender roles, VAWG, and associated factors. METHODS: We used baseline data from a cluster randomised control study. Interviews were conducted in 40 public schools in Hyderabad, with 25-65 children per school. Questions were asked about attitudes toward gender roles, peer-to-peer perpetration, and victimization experiences, and family life, including father- or in-law-to- mother violence and food security. Multiple regression models were built of factors associated with gender attitudes for boys and girls. RESULTS: Our result have shown youth attitudes endorsing patriarchal gender beliefs were higher for boys, compared to girls. The multiple regression model showed that for boys, patriarchal gender attitudes were positively associated with hunger, depression, being promised already in marriage, and being a victim and/or perpetrator of peer violence. For girls gender attitudes were associated with hunger, experiencing corporal punishment at home, and being a perpetrator (for some, and victim) of peer violence. CONCLUSION: Youth patriarchal attitudes are closely related to their experience of violence at school and for girl's physical punishment, at home and for boys being promised in early marriage. We suggest that these variables are indicators of gender norms among peers and in the family. The significance of peer norms is that it provides the possibility that school-based interventions which work with school peers have the potential to positively impact youth patriarchal gender attitudes and foster attitudes of gender equality and respect, and potentially to decrease youth victimization and perpetration.

Growing concerns exist about violent crimes perpetrated by U.S. military personnel. Although interventions exist to reduce violent crimes in high-risk populations, optimal implementation requires evidence-based targeting. The goal of the current study was to use machine learning methods (stepwise and penalized regression; random forests) to develop models to predict minor violent crime perpetration among U.S. Army soldiers. Predictors were abstracted from administrative data available for all 975,057 soldiers in the U.S. Army 2004-2009, among whom 25,966 men and 2728 women committed a first founded minor violent crime (simple assault, blackmail-extortion-intimidation, rioting, harassment). Temporally prior administrative records measuring socio-demographic, Army career, criminal justice, medical/pharmacy, and contextual variables were used to build separate male and female prediction models that were then tested in an independent 2011-2013 sample. Final model predictors included young age, low education, early career stage, prior crime involvement, and outpatient treatment for diverse emotional and substance use problems. Area under the receiver operating characteristic curve was 0.79 (for men and women) in the 2004-2009 training sample and 0.74-0.82 (men-women) in the 2011-2013 test sample. 30.5-28.9% (men-women) of all administratively-recorded crimes in 2004-2009 were committed by the 5% of soldiers having highest predicted risk, with similar proportions (28.5-29.0%) when the 2004-2009 coefficients were applied to the 2011-2013 test sample. These results suggest that it may be possible to target soldiers at high-risk of violence perpetration for preventive interventions, although final decisions about such interventions would require weighing predicted effectiveness against intervention costs and competing risks.

PURPOSE: To examine the association between exposures to violence in childhood, including exposure to multiple forms of violence, with young men's perpetration of intimate partner violence (IPV) in Malawi. METHODS: We analyzed data from 450 ever-partnered 18- to 24-year-old men interviewed in the Malawi Violence Against Children and Young Woman Survey, a nationally representative, multistage cluster survey conducted in 2013. We estimated the weighted prevalence for perpetration of physical and/or sexual IPV and retrospective reporting of experiences of violence in childhood and examined the associations between childhood experiences of violence and perpetration of IPV using logistic regression. RESULTS: Among young men in Malawi, lifetime prevalence for perpetration of sexual IPV (24%) was higher than for perpetration of physical IPV (9%). In logistic regression analyses, the adjusted odds ratios for perpetration of sexual IPV increased in a statistically significant gradient fashion, from 1.2 to 1.4 to 3.7 to 4.3 for young men with exposures to one, two, three, and four or more forms of violence in childhood, respectively. CONCLUSIONS: Among young men in Malawi, exposure to violence in childhood is associated with an increased odds of perpetrating IPV, highlighting the need for programs and policies aimed at interrupting the intergenerational transmission of violence.

BACKGROUND: Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration. METHODS: This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health. We used logistic regression to examine the associations of financial stressors and each type of IPV (minor, severe, causing injury), and multinomial logit regression to examine the associations of financial stressors and patterns of co-occurring types of IPV perpetration (only minor; only severe; minor and severe; minor, severe, and causing injury; compared with no perpetration). RESULTS: Fewer men perpetrated threats/minor physical IPV (6.7 %) or severe physical IPV (3.4 %) compared with women (11.4 % and 8.8 %, respectively). However, among physical IPV perpetrators, a higher percentage of men (32.0 %) than women (21.0 %) reported their partner was injured as a result of the IPV. In logistic regression models of each type of IPV perpetration, both the number of stressors experienced and several types of financial stressors were associated with perpetrating each type of IPV. Utilities nonpayment, housing nonpayment, food insecurity, and no phone service were associated with increased odds of perpetrating each form of IPV in adjusted analysis. Eviction was associated with perpetrating severe physical IPV but not threats/minor IPV or IPV causing injury. In multinomial logit regression comparing patterns of IPV perpetration to perpetrating no physical IPV, the relationships of financial stressors were less consistent. Food insecurity was associated with perpetrating only minor physical IPV. Comparatively, overall number of financial stressors and four types of financial stressors (utilities nonpayment, housing nonpayment, food insecurity, and disconnected phone service) were associated with perpetrating all three forms of physical IPV. CONCLUSIONS: Combined with prior research, our results suggested interventions to improve financial well-being may be a novel way to reduce physical IPV perpetration.
RESUMO
BACKGROUND: Although interventions exist to reduce violent crime, optimal implementation requires accurate targeting. We report the results of an attempt to develop an actuarial model using machine learning methods to predict future violent crimes among US Army soldiers. METHOD: A consolidated administrative database for all 975 057 soldiers in the US Army in 2004-2009 was created in the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS). Of these soldiers, 5771 committed a first founded major physical violent crime (murder-manslaughter, kidnapping, aggravated arson, aggravated assault, robbery) over that time period. Temporally prior administrative records measuring socio-demographic, Army career, criminal justice, medical/pharmacy, and contextual variables were used to build an actuarial model for these crimes separately among men and women using machine learning methods (cross-validated stepwise regression, random forests, penalized regressions). The model was then validated in an independent 2011-2013 sample. RESULTS: Key predictors were indicators of disadvantaged social/socioeconomic status, early career stage, prior crime, and mental disorder treatment. Area under the receiver-operating characteristic curve was 0.80-0.82 in 2004-2009 and 0.77 in the 2011-2013 validation sample. Of all administratively recorded crimes, 36.2-33.1% (male-female) were committed by the 5% of soldiers having the highest predicted risk in 2004-2009 and an even higher proportion (50.5%) in the 2011-2013 validation sample. CONCLUSIONS: Although these results suggest that the models could be used to target soldiers at high risk of violent crime perpetration for preventive interventions, final implementation decisions would require further validation and weighing of predicted effectiveness against intervention costs and competing risks.

The relative impact of school transition versus development on peer victimization and bullying perpetration were examined in a natural experiment involving 698 students where half transitioned into middle school from Grade 5 to Grade 6 and the other half remained in their elementary school over the same period. Results indicated that, on average, peer victimization decreased over the transition period while bullying perpetration remained stable for the whole sample. Multilevel modeling was used to investigate the effects of school transition and sex on changes in victimization and perpetration. Results indicated that the effect of transition status on changes in peer victimization was moderated by sex. Middle school transition status predicted decreases in peer victimization for girls, but not for boys, who transitioned. However, school transition status and participants' sex (and their interaction) did not predict changes in perpetration over time. Our findings indicate that changes in student involvement with peer victimization are better understood as a contextual rather than a typical developmental process, whereas bullying perpetration may be better understood as developmental.
