Overt and relational aggression in adolescents: social-psychological adjustment of aggressors and victims.

Examined the relative and combined associations among relational and overt forms of aggression and victimization and adolescents' concurrent depression symptoms, loneliness, self-esteem, and externalizing behavior. An ethnically diverse sample of 566 adolescents (55% girls) in Grades 9 to 12 participated. Results replicated prior work on relational aggression and victimization as distinct forms of peer behavior that are uniquely associated with concurrent social-psychological adjustment. Victimization was associated most closely with internalizing symptoms, and peer aggression was related to symptoms of disruptive behavior disorder. Findings also supported the hypothesis that victims of multiple forms of aggression are at greater risk for adjustment difficulties than victims of one or no form of aggression. Social support from close friends appeared to buffer the effects of victimization on adjustment.     

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。     

Distinguishing Proactive and Reactive Aggression in Chinese Children

This study examined proactive and reactive aggression and their relation to psychosocial adjustment in three samples (N = 767, 368 girls, M age = 10.03) of Chinese school age children. Confirmatory factor analyses revealed that a two-factor model which distinguished both proactive and reactive aggression fit the data reasonably well, and also fit the data better than a single-factor model in all three samples. The distinction between proactive and reactive aggression was found for both boys and girls. Reactive aggression was more strongly related to reciprocated friendship (negatively), peer victimization, emotion dysregulation, hostile attributions of others' behavior in ambiguous social situations, and self-reported loneliness and social anxiety (positively) than was proactive aggression. Proactive aggression was related to positive outcome expectancies and efficacy beliefs of aggression for boys but not for girls, but the significant gender difference was only found for positive outcome expectancies. The findings suggest that proactive and reactive aggression represent two distinct forms of aggression which are associated with specific adjustment outcomes in Chinese children.     

Friendships with Peers Who are Low or High in Aggression as Moderators of the Link between Peer Victimization and Declines in Academic Functioning

This paper reports two prospective investigations of the role of friendship in the relation between peer victimization and grade point averages (GPA). Study 1 included 199 children (105 boys, 94 girls; mean age of 9.1 years) and Study 2 included 310 children (151 boys, 159 girls; mean age of 8.5 years). These children were followed for two school years. In both projects, we assessed aggression, victimization, and friendship with a peer nomination inventory, and we obtained children's GPAs from a review of school records. Peer victimization was associated with academic declines only when children had either a high number of friends who were above the classroom mean on aggression or a low number of friends who were below the classroom mean on aggression. These results highlight the importance of aggression levels among friends for the academic adjustment of victimized children.     

Interactive Links Between Theory of Mind,Peer Victimization,and Reactive and Proactive Aggression

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.     

Lonely in the crowd: Recollections of bullying

This study examined the long‐term correlates of victimization in school with aspects of functioning in adult life, using a specially designed Retrospective Bullying Questionnaire, which also included questions about short‐term effects (e. g. suicidal ideation and intrusive memories) and victimization experiences in adulthood. Current relationship quality was assessed in terms of self‐perception, attachment style and friendship quality. In total, 884 adults (35% male) from two occupations (teacher, student) and three countries (Spain, Germany, UK) participated. Victims and especially stable victims (in both primary and secondary school) scored lower on general self‐esteem and higher on emotional loneliness, and reported more difficulties in maintaining friendships, than non‐victims. Victims in secondary school had a lower self‐esteem in relation to the opposite sex and were more often fearfully attached. The data revealed additional differences by gender, occupation and country level, but no further interactions with victim status. This indicates a general association between victimization in school and quality of later life predominately robust to variations in gender, occupation and country. Possible limitations caused by the retrospective nature of victimization reports are acknowledged.     

Relation of Depression and Anxiety to Self‐ and Peer‐Reported Relational Aggression

The primary purpose of this multimethod and multimeasure study was to identify how the peer relationships of Australian adolescents (ages 9–15 years; N = 335) at school, including relational aggression and victimization, correlated with their symptoms of depression and anxiety. Moreover, relational aggression and victimization were measured via both self‐ and peer report, and discrepancies between reports were considered as correlates of symptoms and peer relationship status. Adolescents who reported more symptoms of depression and anxiety also self‐reported more relational victimization and reported their peers as less trustworthy. Adolescents who overreported their own relational victimization and aggression compared with peer report had more symptoms compared with those who agreed with their peers or underreported their aggression and victimization. Adolescents who underreported their own aggression were not only more socially prominent but were also more disliked by their peers. When considered independent of self‐reports, no measure of peer‐reported peer status, aggression, or victimization was associated with depressive symptoms; but adolescents reported as more accepted by their peers had fewer anxiety symptoms. Longitudinal research should be conducted to examine adolescents' increasing socioemotional problems as correlates of discrepancies between self‐ and peer reports of relational aggression and victimization.

Prospective Associations Between Peer Victimization and Internalizing Symptoms in Adolescence: The Protective Role of Hope

Youth who experience aggression at the hands of peers are at an increased risk for a variety of adjustment difficulties, including depressive and anxiety symptoms and lower self-esteem. The links between peer victimization and internalizing problems are robust, but less work has been done to identify individual-level protective factors that might mitigate these outcomes. The current study investigated whether hope served as a moderator of the prospective links from peer victimization to depressive and anxiety symptoms and self-esteem during adolescence. Participants included 166 high school students (64% female; 88% Black/African American). Youth completed self-report measures at three different time points across the Spring semester of an academic year. As predicted, hope interacted with peer victimization to predict changes in depressive and anxiety symptoms over the course of the semester. That is, for youth with low levels of hope, peer victimization predicted more stable patterns of depressive and anxiety symptoms. For adolescents with average levels of hope, however, peer victimization did not influence anxiety and depressive symptoms over time. Finally, for adolescents with high levels of hope, peer victimization predicted greater decreases in anxiety symptoms over time. Hope did not interact with peer victimization to predict self-esteem. Rather, hope uniquely predicted higher levels of self-esteem, whereas peer victimization uniquely predicted lower levels of self-esteem. The current study provides initial support for the notion that hope can serve as a protective factor among youth who are victims of peer aggression.

     

When is peer rejection justifiable? Children's understanding across two cultures

This study investigated how Korean (N = 397) and U.S. (N = 333) children and adolescents (10 and 13 years of age) evaluated personality (aggression, shyness) and group (gender, nationality) characteristics as a basis for peer rejection in three contexts (friendship rejection, group exclusion, victimization). Overall, peer rejection based on group membership was viewed as more unfair than peer rejection based on personality traits. Children viewed friendship rejection as more legitimate than group exclusion or victimization and used more personal choice reasoning for friendship rejection than for rejection in any other context. Although there were a few cultural differences, overall, the findings provided support for the cultural generalizability of social reasoning about peer rejection.     

Do Friends’ Characteristics Moderate the Prospective Links between Peer Victimization and Reactive and Proactive Aggression?

This study examined (a) the predictive link between peer victimization and children’s reactive and proactive aggression, and (b) the potential moderating effect of reciprocal friends’ reactive and proactive aggression in this context. The study also examined whether these potential moderating effects of friends’ characteristics were stronger with respect to more recent friends compared to previous friends. Based on a convenience sample of 658 twin children (326 boys and 332 girls) assessed in kindergarten and first grade, the results showed that peer victimization uniquely predicted an increase in children’s teacher-rated reactive aggression, but not teacher-rated proactive aggression. The relation of peer victimization to increased reactive aggression was, however, moderated by recent ˉ not previous ˉ reciprocal friends’ similarly aggressive characteristics. These findings, however, tended to be mostly true for boys, but not for girls. The findings are discussed in terms of their theoretical and practical implications for victimized children’s risk of displaying reactive and proactive aggressive behaviors.

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.     

Proactive and Reactive Aggression and Physical Activity

The current study examined relations between physical activity and proactive and reactive aggression. Additionally, physical activity was examined as a potential moderator of the associations between these subtypes of aggression and peer delinquency. Relations were examined in a community recruited sample of 89 children (56% male, 74% Caucasian) ranging from 9 to 12 years of age (M = 10.44, SD = 1.14). As expected, physical activity was negatively related to proactive aggression and unrelated to reactive aggression. Moreover, physical activity moderated the relation between proactive aggression and peer delinquency, such that at high levels of physical activity, proactive aggression was unrelated to peer delinquency but at low levels of physical activity, proactive aggression was positively associated with peer delinquency. Thus, physical activity may be an important factor to consider when understanding the link between aggression and other problem behavior, as physical activity appears to impact the link between proactive aggression and delinquent peer affiliations.     

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.     

Children’s ADHD Symptoms and Friendship Patterns across a School Year

Symptoms of attention-deficit/hyperactivity disorder (ADHD) in elementary school-age children are associated with poor relationships with classroom peers, as indicated by poor social preference, low peer support, and peer victimization. Less is known about how friendship patterns relate to ADHD symptoms, or how friendships may buffer risk for negative peer experiences. Participants were 558 children in 34 classrooms (grades K-5). At the beginning (fall) and end (spring) of an academic year, children completed (a) sociometric interviews to index friendship patterns and social preference, and (b) self-report questionnaires about their support and victimization experiences from classmates. In fall, higher teacher-reported ADHD symptoms were associated with children having more classmates with no friendship ties (non-friends) and who the child nominated but did not receive a nomination in return (unreciprocated friends), and with having fewer classmates with mutual friendship ties (reciprocated friends) and who nominated the child but the child did not nominate in return (unchosen friends). Higher fall ADHD symptoms predicted more non-friend classmates, poorer social preference, and more victimization in the spring, after accounting for the same variables in fall. However, having many reciprocated friends (and to a lesser extent, many unchosen friends) in fall buffered against the trajectory between fall ADHD symptoms and poor peer functioning in spring. By contrast, having many unreciprocated friends in fall exacerbated the trajectory between fall ADHD symptoms and poor peer functioning in spring. Thus, elevated ADHD symptoms are associated with poorer friendship patterns, but reciprocated friendship may protect against negative classroom peer experiences over time.

     

青少年早期同伴拒绝、同伴侵害与抑郁的关系：交叉滞后分析

采用间隔1年的追踪设计,使用结构方程建模对1068名青少年早期个体的同伴拒绝、同伴侵害与抑郁间的关系进行交叉滞后分析。结果发现,（1）在不同时间点上,同伴拒绝、同伴侵害和青少年抑郁之间存在显著正相关;（2）先前的抑郁水平对随后个体遭受的身体侵害和关系侵害均有显著预测作用,而先前的同伴侵害不能显著预测随后青少年的抑郁水平。抑郁对同伴拒绝、以及同伴拒绝对抑郁的预测作用均不显著。（3）同伴拒绝、同伴侵害与抑郁间的关系具有跨性别的一致性。这表明,青少年早期同伴侵害和抑郁间存在单向预测关系,抑郁导致同伴侵害。     

Bidirectional Associations between Peer Victimization and Functions of Aggression in Middle Childhood: Further Evaluation across Informants and Academic Years

The current 3-wave study examined bidirectional associations between peer victimization and functions of aggression across informants over a 1-year period in middle childhood, with attention to potential gender differences. Participants included 198 children (51% girls) in the third and fourth grades and their homeroom teachers. Peer victimization was assessed using both child- and teacher-reports, and teachers provided ratings of reactive and proactive aggression. Cross-classified multilevel cross-lagged models indicated that child-reports, but not teacher-reports, of peer victimization predicted higher levels of reactive aggression within and across academic years. Further, reactive aggression predicted subsequent increases in child- and teacher-reports of peer victimization across each wave of data. Several gender differences, particularly in the crossed paths between proactive aggression and peer victimization, also emerged. Whereas peer victimization was found to partially account for the stability of reactive aggression over time, reactive aggression did not account for the stability of peer victimization. Taken together with previous research, the current findings suggest that child-reports of peer victimization may help identify youth who are risk for exhibiting increased reactive aggression over time. Further, they highlight the need to target reactively aggressive behavior for the prevention of peer victimization in middle childhood.     

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.     

Temperament, ADHD and peer relations among schoolchildren: the mediating role of school bullying

The goal of the study is to investigate the link between temperament, attention-deficit hyperactivity disorder (ADHD) symptoms, social preference, bullying and victimization. The study sample consisted of 195 children attending the fourth and fifth grade (age 8-10), their mothers and their teachers. A multiinformant approach was used: mothers were interviewed about the temperament of their children; teachers were asked about ADHD symptoms; children responded to a peer nominations inventory designed to investigate their roles as bullies and/or victims and their social preferences (liked and disliked peers). A Structural Equation Model multigroup analysis (males and females) was used to test the relationships among variables hypothesized by the authors. The analysis showed that temperamental variables have a direct relation to ADHD symptoms, that ADHD has a direct relation to bullying behavior in males and to victimization in females and that bullies and victims are less well accepted than peers who belong to neither category. ADHD has only an indirect relation to social preference through the mediating role of school bullying.     

Functions of Aggression and Peer Victimization in Elementary School Children: the Mediating Role of Social Preference

This study examined whether social preference was a mechanism that explained the relation between proactive and reactive aggression and peer victimization. Participants were 494 children in grades 2–5. Proactive and reactive aggression was assessed via a self-report measure and indices of social preference and peer victimization were assessed via a peer nomination inventory. Data was collected during the fall and spring of two academic years. The relations among aggression, social preference, and peer victimization varied as a function of aggression and gender. For girls, reactive aggression was a significant negative predictor of social preference. Findings also revealed social preference mediated the relation between reactive aggression and peer victimization for girls. This pathway did not hold for boys. There was some evidence that proactive aggression was negatively associated with peer victimization, but only for girls. Findings from the current study suggest social preference may be a key mechanism through which reactive aggression is associated with future victimization for girls. Boys’ aggression was not related to subsequent peer victimization. Future research and intervention efforts should consider gender differences and the function of aggression when investigating children’s peer victimization experiences.
