Peer Victimization, Aggression, and Their Co-Occurrence in Middle School: Pathways to Adjustment Problems

An ethnically diverse sample of 6th-grade students completed peer nomination procedures that were used to create subgroups of students with reputations as victims, aggressors, aggressive victims, and socially adjusted (neither aggressive nor victimized). Self-report data on psychological adjustment, attributions for peer harassment, and perceived school climate were gathered. In addition, homeroom teachers rated participating students on academic engagement and students' grades were collected from school records. Victims reported the most negative self-views, aggressors enjoyed the most positive self-views, and aggressive victims fell between these two groups, although their psychological profile more closely resembled that of victims. However, all three subgroups encountered more school adjustment problems when compared to their socially adjusted classmates. Different pathways to school adjustment problems for aggressors and victims were examined. For victims, characterological self-blame for victimization and psychological maladjustment were the key mediators, whereas for aggressors, the significant pathway was mainly through perceived unfairness of school rules. Analyses by ethnicity revealed that African American boys were most likely to be perceived as aggressive and as aggressive victims and they were doing most poorly in school. Implications for intervention with subgroups of problem behavior youth and the particular vulnerabilities of African American adolescents were discussed.     

Male and Female Victims of Male Bullies: Social Status Differences by Gender and Informant Source

We examine two sources of variation in victims’ social adjustment: (a) the informant who identifies a child as victim (i.e., peer, self, or both), and (b) victim gender. Peer and self nominations were provided by 508 fourth and fifth graders from the Midwest U.S. Girls were more likely than boys to be victimized, and victims were evenly distributed among informant source. Self-nominated female victims had lower social status and were involved in more antipathies than their peer-nominated counterparts. Among boys, self-and-peer reported victims had the lowest social status. Having friends was associated with positive social adjustment. Implications are discussed for at-risk victim subgroups: girls whose self-reports of victimization are not validated by others, and boys whose victimization is publicly acknowledged.     

Psychosomatic complaints in adolescence: Untangling the relationship between offline and online peer victimization,psychosomatic complaints and social support

Offline peer victimization has been linked to psychosomatic complaints. As peer victimization is no longer limited to adolescents’ offline relationships, it is crucial that we investigate whether online peer victimization has similar negative consequences. To date, no study systematically investigated the unique contribution of online vs. offline peer victimization on psychosomatic complaints, and the possible protective effect of social support. The current study disentangled offline and online peer victimization by distinguishing four victim types: non-victims, offline, online, and dual victims (N = 897, 9-to-18-year-olds). In addition, we assessed perceived social support from teachers, parents, friends and classmates. A main effect was found for victim type on psychosomatic complaints. Victims (offline or dual) reported more psychosomatic complaints than non-victims. Notably, online victims reported similar levels of psychosomatic complaints compared to non-victims. Furthermore, although social support from parents and classmates was related to fewer psychosomatic complaints, only limited support was found for a buffering effect of social support.     

Peer Victimization and Parental Psychological Control in Adolescence

With a sample of 831 U.S. adolescents (49% girls) followed from 9th to 11th grade, the directionality of the association between school-based peer victimization and adolescents’ perception of their parents’ psychological control were examined. Possible mediating influences of internalizing symptoms were also explored. The results highlight the relevance of adolescent-to-parent influences during adolescence by demonstrating that physical peer victimization was predictive of increases in mother’s psychological control but parental psychological control did not predict subsequent peer victimization. These direct effects were present above and beyond the contribution of adolescent internalizing symptoms to higher parental psychological control. Practical implications of the primacy of adolescent-to-parent influences in predicting the social adjustment of victims of peer harassment are discussed.     

Subtypes of Victims and Aggressors in Children's Peer Groups

This study reports an investigation of the behavioral profiles and psychosocial adjustment of subgroups of victims and aggressors in elementary school peer groups. Peer nomination scores for aggression and victimization were used to classify 354 inner-city children (mean age of 10.3 years) into one of four subgroups: aggressive victims, nonaggressive victims, nonvictimized aggressors, and normative contrasts. Subgroup comparisons were then conducted using multi-informant assessment of social behavior, social acceptance-rejection, behavioral regulation, academic functioning, and emotional distress. Children in each of the victim-aggressor subgroups were characterized by a degree of social and behavioral maladjustment. However, impairments in behavioral and emotional regulation were most evident for the aggressive victim subgroup. Aggressive victims were also characterized by academic failure, peer rejection, and emotional distress. The results of this investigation highlight the distinctive nature of the aggressive victim subgroup.     

Stability of Early Identified Aggressive Victim Status in Elementary School and Associations with Later Mental Health Problems and Functional Impairments

Aggressive victims—children who are both perpetrators and victims of peer aggression—experience greater concurrent mental health problems and impairments than children who are only aggressive or only victimized. The stability of early identified aggressive victim status has not been evaluated due to the fact that most studies of aggressor/victim subgroups have focused on preadolescents and/or adolescents. Further, whether children who exhibit early and persistent patterns of aggression and victimization continue to experience greater mental health problems and functional impairments through the transition to adolescence is not known. This study followed 344 children (180 girls) previously identified as socially adjusted, victims, aggressors, or aggressive victims at Grade 1 (Burk et al. 2008) to investigate their involvement in peer bullying through Grade 5. The children, their mothers, and teachers reported on children’s involvement in peer aggression and victimization at Grades 1, 3, and 5; and reported on internalizing symptoms, externalizing symptoms, inattention and impulsivity, as well as academic functioning, physical health, and service use at Grades 5, 7, and 9. Most children categorized as aggressive victims in Grade 1 continued to be significantly involved in peer bullying across elementary school. Children with recurrent aggressive victim status exhibited higher levels of some mental health problems and greater school impairments across the adolescent transition when compared to other longitudinal peer status groups. This study suggests screening for aggressive victim status at Grade 1 is potentially beneficial. Further early interventions may need to be carefully tailored to prevent and/or attenuate later psychological, academic, and physical health problems.     

Peer and teacher bullying/victimization of South Australian secondary school students: Prevalence and psychosocial profiles

This study examined the nature and prevalence of bullying/victimization by peers and teachers reported by 1,284 students (mean age = 15.2 years) drawn from a representative sample of 25 South Australian government and private schools. Students completed a self‐report survey containing questions relating to teacher and peer‐related bullying, measures of psychosocial adjustment, and personality. The results showed that students could be clearly differentiated according to the type of victimization they had experienced. Students reporting peer victimization typically showed high levels of social alienation, poorer psychological functioning, and poorer self‐esteem and self‐image. By contrast, victims of teacher victimization were more likely to be rated as less able academically, had less intention to complete school and were more likely to be engaged in high‐risk behaviours such as gambling, drug use and under‐age drinking. Most bullying was found to occur at school rather than outside school and involved verbal aggression rather than physical harm. Boys were significantly more likely to be bullied than girls, with the highest rates being observed amongst boys attending single‐sex government schools. Girls were more likely to be subject to bullying if they attended coeducational private schools. The implications of this work for enhancing school‐retention rates and addressing psychological distress amongst adolescent students are discussed.     

Self and peer nominations of bullying: An analysis of incident rates,individual differences,and perceptions of the working environment

Within workplace bullying research, the use of different criteria to identify victim samples, and a tendency to rely on self-reported victimization without including reports from other stakeholders have been considered major methodological problems associated with incidence studies (Cowie, Naylor, Rivers, Smith, & Pereira, 2002; Hoel, Rayner, & Cooper, 1999; Randall, 2001). Using diverse criteria to identify victim and perpetrator samples (such as self report, peer report, and self- and peer report), this study found rates of victimization and bullying varied quite considerably. Rates for victims ranged from 3.9% to 39.6% and for perpetrators from 2.7% to 19.3%. Differences in personality and perceptions of the organizational environment were then examined between victim/bully groups and a control sample. Results indicated that all victim samples differed significantly from controls on stability. However, self- and peer-reported victims differed significantly from controls on both the poised and relaxed subscales, whereas self-reported victims only differed significantly on the relaxed subscale. Additionally, self- and peer-reported victims were the only group that significantly differed from controls in their views of the negative aspects of the work environment. The notion that victim and perpetrator samples are not homogenous groups and considerations of why this is the case are discussed.     

Connected and Isolated Victims of Relational Aggression: Associations with Peer Group Status and Differences between Girls and Boys

Some adolescents who are relationally victimized by gossip and ostracism have limited close connections to a peer or friendship group, but victimization also can be group-based, occurring between or within friendship groups. The purpose of this study was to test gender differences in these two forms of victimization, referred to as isolated and connected victimization, and to test associations of each form with peer status (social prominence and preference within the peer group) and aggressive behavior. We expected that associations between victimization, especially connected victimization, peer status and aggressive behavior would differ for boys and girls. Australian students (N = 335, M _age = 12.5 years) self-reported victimization, and nominated peers who were victimized, accepted, rejected, socially prominent, and unpopular. Connected and isolated forms of victimization were correlated, but differences were found in their correlations with other measures and by gender. Especially when reported by peers, adolescents higher in connected victimization were also higher in both aggression and social prominence (i.e., they were more popular and considered leaders); yet, they were also more disliked (rejected). In contrast to connected victimization, isolated victimization was associated with negative peer status only, and weakly and inconsistently associated with aggression. Finally, gender moderation was found, which showed a pattern of aggression, prominence and dislike among adolescent females who were connected victims, but this pattern was not nearly as pronounced in their male counterparts.

青少年友谊网络与受欺凌的共同变化关系：一项纵向社会网络分析研究

欺凌是一种涉及多类行为和多主体互动的群体过程, 但是已有研究很少在同伴的群体互动和关系变化过程中研究欺凌相关行为的发展。尤其是受欺凌作为一种被动承受而非主动选择的行为结果, 对其在同伴情境中的变化过程研究更为有限。本研究从青少年的友谊网络与其受欺凌的共变关系入手, 采用纵向社会网络分析法, 对来自26个班1406名学生进行为期1年的3个时间点(七年级末、八年级上学期末、八年级下学期末)的追踪研究, 结果发现：(1)受欺凌影响群体内友谊关系的建立：受欺凌水平高的青少年更难以与同伴建立朋友关系(同伴回避效应), 且更倾向于选择同样受欺凌水平高的个体作为朋友(同伴选择效应); (2)友谊关系影响受欺凌水平的变化：在群体中拥有更多朋友关系的青少年, 其受欺凌水平会逐渐降低(同伴保护效应); 但另一方面, 拥有高受欺凌水平朋友的青少年, 自己的受欺凌水平会随着时间呈增高趋势(同伴影响效应); (3)随着时间的发展, 女生的受欺凌水平比男生更容易降低(性别影响效应)。研究结果揭示了友谊网络和受欺凌的共变关系, 为校园欺凌群体干预提供启示。     

Using latent class analysis to identify aggressors and victims of peer harassment

This study used latent class analysis (LCA) to identify and classify individuals into aggressor and victim latent classes. Participants were over 2,000 sixth grade students who completed peer nomination procedures that identified students who had reputations as perpetrators and/or victims of physical, verbal, or relational harassment. Results showed five latent classes. Consistent with previous research, LCA identified latent classes of victims, aggressors, and socially adjusted students. However, rather than a single aggressive-victim subgroup, LCA identified latent classes of highly-victimized aggressive-victims and highly-aggressive aggressive-victims. Comparisons showed differences in mean profiles and classification criteria between LCA and traditional dichotomization approaches. Adjustment outcomes showed that highly-victimized aggressive-victims generally experienced greater negative psychological and social adjustment outcomes than highly-aggressive aggressive-victims. Implications of these findings for better assessment of victim and aggressor subgroups were discussed.     

The evaluation of perpetrators and victims of peer victimization: An extended crossed‐categorization approach

This research uses a crossed‐categorization design for examining the perception of peer victimization. Using vignettes and an experimental design, perpetrator and victim evaluations of Dutch and Turkish‐Dutch early adolescents were examined in terms of ethnic and gender similarities between (1) respondent and perpetrator, (2) respondent and victim, and (3) perpetrator and victim. When the perpetrator was a double‐ingroup member of the respondent (same ethnicity and same gender), perpetrators were evaluated less negatively and victims less positively than when the perpetrator was a single (gender or ethnicity) or double‐outgroup member. Further, when the victim was a double‐ingroup member of the respondent, perpetrators were evaluated more negatively and victims more positively. No perpetrator–victim crossed‐categorization effects were found for perpetrator and victim evaluations. Perceived norms of intervention in the classroom had the expected main effects but did not moderate the crossed‐categorization effects. The usefulness of a crossed‐categorization approach for examining the perception of negative peer behavior is discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Psychological Dating Violence Perpetration and Victimization: Trajectories From Middle to High School

Despite evidence documenting the negative consequences, psychological dating violence occurs frequently in adolescent dating relationships. No information exists on the trajectories that adolescents follow and their association to nonphysical peer violence. The sample comprised 624 randomly selected 6th graders. In yearly surveys from 6th through 12th grade, 550 of the 624 students reported dating at least twice during the 3 months prior to completing the survey. These students responded to questions about frequency of engagement in psychological dating violence perpetration and victimization. We used Proc TRAJ to identify developmental trajectories of behavior over time and generalized estimating equation models to examine the associations of the trajectories and peer aggression. Adolescents followed three distinct developmental trajectories related to psychological dating violence victimization and perpetration: low, increasing, and high. Based on the joint probabilities of victimization and perpetration, we identified four predominant groups: low victimization/low perpetration (LVLP; 36%), increasing victimization/increasing perpetration (40%), high victimization/high perpetration (HVHP; 15%), and increasing victimization/low perpetration (IVLP; 7%). The LVLP had significantly more boys and White students; the HVHP group had an even gender distribution and more African‐American students. For all groups, peer aggression decreased from Grade 6 to 12; students in the HVHP group reported the highest peer aggression, and students in the LVLP reported the lowest peer aggression. Findings suggest a strong, reciprocal relationship in the developmental trajectories of adolescents who experience and perpetrate psychological dating violence. Those highly engaged in these behaviors were also more likely to be violent toward peers. Aggr. Behav. 38:510‐520, 2012. © 2012 Wiley Periodicals, Inc.     

A Cluster Analytic Investigation of Victimization Among High School Students

ABSTRACT

Victimization experiences of 504 racially diverse high school students were evaluated. Questionnaires assessed sexual harassment victimization, psychological and physical abuse in dating relationships, peer victimization, childhood sexual abuse, school belonging, and psychological functioning. Results showed that 70% of students had been sexually harassed by peers during the past year, 40% had experienced physical dating violence, 66% had been victimized by emotional abuse in dating relationships, and 54% had been bullied. A cluster analysis of victimization measures revealed heterogeneity in victimization experiences; five distinct groups of students emerged. Individuals who had experienced multiple forms of victimization tended to have lower psychological well-being and a diminished sense of school belonging. Results are discussed in terms of implications for clinical and school interventions.     

Individual and social network predictors of the short‐term stability of bullying victimization in the United Kingdom and Germany

Background. There is still relatively little research on the social context within which bullying develops and remains stable. Aim. This study examined the short‐term stability of bullying victimization among primary school students in the United Kingdom and Germany (mean age, 8.9 years) and the individual and social network factors that contributed to remaining a victim of bullying. Sample. The sample consisted of 454 children (247 males and 207 females). Methods. Participants completed questionnaires on bullying victimization at three assessment points over a 9‐week period. Other measures consisted of self‐reported demographic, peer, and family relationship characteristics. Social network indices of density, reciprocity, and hierarchy were constructed using friendship and peer acceptance nominations. Results. Relative risk analyses indicated a six‐fold increased risk of remaining a victim at consequent follow‐ups, compared to a child not victimized at baseline becoming a victim over the follow‐up period. Individual characteristics explained substantially more variance in the stability of bullying victimization than class‐level factors. Hierarchical logistic regression analyses revealed that being victimized by siblings and being rejected by peers predicted remaining a victim over a 9‐week period. Conclusions. Bullying victimization among primary school students proved moderately stable over a 9‐week period. Individual characteristics were more influential in predicting the stable victim role than class‐level factors. Our findings have implications for the identification of stable victims in primary school and early preventative bullying programs.     

Relation between childhood peer victimization and adult perfectionism: are victims of indirect aggression more perfectionistic?

Using two independent samples and two different measures of perfectionism, this study investigated the hypothesized relation between retrospective accounts of perceived peer-inflicted emotional abuse during childhood and perfectionism in adulthood. Emotional victimization ('indirect' aggression) is characterized by behavior in which mental harm is inflicted on victims through exclusionary acts, gossiping, and rumor spreading. Study one: Self-reported questionnaires of indirect victimization [DIAS; Bjorkqvist, Lagerspetz, and Osterman, 1992] and perfectionism [multidimensional perfectionism scale; Hewitt and Flett, 1991] were administered to 162 (mean age=20.14 years) female undergraduate psychology students. Results support the predicted positive relationship between recalled indirect peer victimization and current socially prescribed/self-oriented perfectionism. Study two: self-reports of indirect peer victimization and perfectionism (eating disorder inventory-perfectionism) were collected from 196 (mean age=19.5 years) female undergraduate students. Again, recalled indirect peer victimization was a statistically significant predictor of current socially prescribed/self-oriented perfectionism whereas recalled direct (physical, verbal) peer victimization held no relation. Discussion addresses the implications of these results, which hold importance for both the bullying and perfectionism literatures.     

童年中期身体侵害、关系侵害与儿童的情绪适应

采用整群抽样法选取2603名小学儿童（平均年龄9.05 ± 0.53岁）作为被试,考察童年中期同伴侵害现象的基本特点,以及同伴侵害与情绪适应（孤独感、社交焦虑和抑郁）的关系。结果发现：（1）在性别差异方面,男生的身体侵害与关系侵害水平均显著高于女生,与身体侵害相比,关系侵害的性别差异程度较小。在同伴侵害的类型特点方面,儿童遭受身体侵害的水平显著高于关系侵害。（2）身体侵害、关系侵害与儿童的各情绪适应指标显著正相关,身体侵害和关系侵害能同时预测儿童的情绪适应不良;并且与身体侵害相比,关系侵害对情绪适应的影响更大。（3）身体侵害与社交焦虑的关系表现出性别差异,即身体侵害能预测女生的社交焦虑,而对男生的社交焦虑不存在预测作用;但同伴侵害与孤独感、抑郁的关系不受性别的调节。总体而言,有同伴侵害经历的男生和女生具有相似的情绪适应问题。     

Peer victimization during adolescence: concurrent and prospective impact on symptoms of depression and anxiety

Background: Peer victimization is ubiquitous across schools and cultures, and has the potential for long-lasting effects on the well-being of victims. To date, research has focused on the consequences of peer victimization during childhood but neglected adolescence. Peer relationships and approval become increasingly important during adolescence; thus, peer victimization at this age may have a damaging psychological impact. Methods: Participants were 5030 adolescents aged 11–16 recruited from secondary schools in the UK. Self-report measures of victimization and symptoms of anxiety and depression were administered on three occasions over a 12-month period. Latent growth models examined concurrent and prospective victimization-related elevations in anxiety and depression symptoms above individual-specific growth trajectories. Results: Peer victimization was associated with a concurrent elevation of 0.64 and 0.56 standard deviations in depression and anxiety scores, respectively. There was an independent delayed effect, with additional elevations in depression and anxiety (0.28 and 0.25 standard deviations) six months later. These concurrent and prospective associations were independent of expected symptom trajectories informed by individual risk factors. Conclusions: Adolescent peer victimization was associated with immediate and delayed elevations in anxiety and depression. Early intervention aimed at identifying and supporting victimized adolescents may prevent the development of these disorders.     

Parental Psychological Control and Peer Victimization among Chinese Adolescents: The Effect of Peer Pressure as a Mediator

Peer victimization is a serious problem among children and adolescents. Family and peers are two of the most proximal and influential microsystems for children. The present study examined the influence of parental psychological control and peer pressure on peer victimization. According to social learning theory and attachment theory, parent–child interactions may serve as a model of peer interactions. Therefore, we proposed the hypothesis that peer pressure functioned as a mediator in the association between parental psychological control and peer victimization. We tested this hypothesis in a sample of Chinese adolescents and examined whether this mediation model varied by gender. Participants were 2382 seventh grade students (1166 girls and 1216 boys) in Beijing, China. The results showed that both parental psychological control and peer pressure were positively associated with peer victimization in Chinese adolescents. Additionally, peer pressure partially mediated the effect of psychological control on peer victimization. Furthermore, multi-group comparisons showed that gender differences existed in the mediation model. The direct effect of psychological control on peer victimization was a little larger in boys, whereas the indirect effect was larger in girls. The findings suggest that parental psychological control contributes to peer victimization in non-Western culture as well. These findings also improve our understanding of the underlying mechanisms involved in peer victimization by interrelating family and peer factors.
