Personal and interpersonal antecedents and consequences of victimization by peers.

This study was designed to determine whether the personal and interpersonal difficulties that characterize victimized children are antecedents of victimization, consequences of victimization, or both. Boys and girls in the 3rd through 7th grades (N?=?173, mean age?=?11.3 years) were assessed on victimization, personal variables (internalizing problems, externalizing problems, and physical strength), and interpersonal variables (number of friends and peer rejection). One year later children were assessed again on all variables. Internalizing problems, physical weakness, and peer rejection contributed uniquely to gains in victimization over time. Moreover, initial victimization predicted increases in later internalizing symptoms and peer rejection. These reciprocal influences suggest the existence of a vicious cycle that supports the strong temporal stability of peer victimization.

The power of friendship: Protection against an escalating cycle of peer victimization.

This study examined 2 aspects of friendship (presence and perceived qualities of a best friend) as moderators of behavioral antecedents and outcomes of peer victimization. A total of 393 children (188 boys and 205 girls) in the 4th and 5th grades (mean age 10 years 7 months) participated during each of 2 waves of data collection in this 1-year longitudinal study. Results indicated that teacher-reported internalizing and externalizing behaviors predicted increases in peer-reported victimization, but the relation of internalizing behaviors to increases in victimization was attenuated for children with a protective friendship. Victimization predicted increases in internalizing and externalizing behaviors but only for children without a mutual best friendship. Results highlight the importance of peer friendships in preventing an escalating cycle of peer abuse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relational and physical forms of peer victimization in preschool.

Recent studies of peer victimization have demonstrated the importance of studying relational as well as physical forms of peer maltreatment for understanding children's social-psychological adjustment problems. Studies in this area have been limited thus far by a focus on school-age children (9–12-year olds). Given the significance of early identification of children's social difficulties for intervention and prevention efforts, this research was designed to assess relational and physical peer victimization among preschool-age children (3–5-year-olds). Results indicated that boys were significantly more physically victimized than girls whereas girls were more relationally victimized. Both relational and physical victims experienced greater adjustment problems than did their peers. Relational victimization contributed unique information about adjustment beyond that provided by physical victimization. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Marital conflict, maternal and paternal parenting, and child adjustment: A test of mediation and moderation.

Parenting was examined as a mediator of associations between marital and child adjustment, and parent gender was examined as a moderator of associations among marital, parental, and child functioning in 226 families with a school-age child (146 boys). Parenting fully mediated associations between marital conflict and child internalizing and externalizing behaviors. Parent gender did not moderate associations when data from the full sample or families with girls only were evaluated. Parent gender did moderate associations when families with boys were evaluated, with the association between marital conflict and parenting stronger for fathers than mothers. A trend suggested fathers' parenting may be more strongly related to internalizing behavior and mothers' parenting may be more strongly related to externalizing behavior in boys.

Individual risk and social risk as interacting determinants of victimization in the peer group.

This study evaluated the hypothesis that the behavior problems that place children at risk for victimization by peers are associated with victimization primarily when children are also at social risk for victimization. Social risk was defined as lacking supportive friends or as being rejected by the peer group. Participants were 229 boys and girls in the 3rd through 7th grades (M age?=?11 years 2 months). As predicted, behavior problems (internalizing problems, externalizing problems, and physical weakness) were more strongly related to victimization when children had few friends, had friends who were incapable of fulfilling a protective function (e.g., were physically weak), or were rejected by peers than when children had more friends, had friends capable of defending them, or were better liked by peers. Results illustrate the principle that individual risk variables depend on social context for expression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Victimization in the Peer Group and Children's Academic Functioning.

This short-term longitudinal investigation focused on associations between victimization in the peer group and academic functioning over a 1-year period. The authors used a multi-informant approach to assess peer victimization, symptoms of depression, and academic outcomes for 199 elementary schoolchildren (average age of 9.0 years; 105 boys, 94 girls). Frequent victimization by peers was associated with poor academic functioning (as indicated by grade point averages and achievement test scores) on both a concurrent and a predictive level. Additionally, the authors' analyses provided some evidence that peer group victimization predicts academic difficulties through the mediating influence of depressive symptoms. Taken together, these results highlight the potential negative impact of victimization by peers on children's academic functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Coping with perceived peer stress: Gender-specific and common pathways to symptoms of psychopathology.

This study investigated gender differences in the moderating and mediating effects of responses to stress on the association between perceived peer stress and symptoms of psychopathology. A sample of 295 middle school students (63.7% female; Mage = 12.39 years, SD = 0.99) completed self-report surveys on stress, coping, and behavioral problems. Involuntary responses to stress (e.g., physiological arousal, intrusive thoughts, impulsive action) mediated the association between perceived stress and anxiety/depression and aggression for girls and for boys. Disengagement coping (e.g., denial, avoidance) partially mediated the association between peer stress and anxiety/depression for boys and for girls. In contrast, disengagement coping mediated the association between peer stress and overt aggression for boys only. Finally, engagement coping (e.g., problem solving, emotion regulation, cognitive restructuring) buffered the indirect effect of peer stress on symptoms of psychopathology for girls only. Implications for prevention and intervention efforts are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Marital Adjustment, Child-Rearing Disagreements, and Overreactive Parenting: Predicting Child Behavior Problems.

Using structural equation modeling, the authors evaluated the hypothesis that the relation between marital adjustment and children's behavior problems is mediated by child-rearing disagreements, whose effects are mediated by parents' overreactive discipline. In a community sample, fully or partially mediated models of internalizing and externalizing behavior problems of 3- to 7-year-old boys (N = 99) and girls (N = 104) were supported for mothers and fathers in 7 of 8 cases. Child-rearing disagreements always mediated the relation of marital adjustment and child behavior problems, and overreactive discipline was a final mediator in 3 cases. More variance was accounted for in mothers' than fathers' ratings. For mothers' ratings, the most variance was accounted for in boys' externalizing and girls' internalizing behavior problems.

Relational and overt forms of peer victimization: A multiinformant approach.

This research addressed 2 limitations of past research on peer victimization: the tendency to study boys only and the tendency to focus on forms of peer maltreatment that are common in boys' peer groups (victimization through overt aggression) but occur much less frequently in girls' peer groups. Peer- and self-report instruments were used to assess a relational form of victimization in addition to the overt form that has been the focus of past research. Results showed that girls were more relationally victimized, whereas boys were more overtly victimized. Both forms of victimization were shown to predict concurrent sociopsychological adjustment problems significantly (e.g., peer rejection, loneliness) beyond aggression. Victims identified through a combination of self- and peer-reports were particularly maladjusted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing the forms and functions of aggression using self-report: Factor structure and invariance of the Peer Conflict Scale in youths.

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.

Emotion dysregulation as a mechanism linking peer victimization to internalizing symptoms in adolescents.

Peer victimization experiences represent developmentally salient stressors among adolescents and are associated with the development of internalizing symptoms. However, the mechanisms linking peer victimization to adolescent psychopathology remain inadequately understood. This study examined emotion dysregulation as a mechanism linking peer stress to changes in internalizing symptoms among adolescents in a longitudinal design. Peer victimization was assessed with the Revised Peer Experiences Questionnaire (M. J. Prinstein, J. Boergers, & E. M. Vernberg, 2001) in a large (N = 1,065), racially diverse (86.6% non-White) sample of adolescents 11–14 years of age. Emotion dysregulation and symptoms of depression and anxiety were also assessed. Structural equation modeling was used to create a latent construct of emotion dysregulation from measures of discrete emotion processes and of peer victimization and internalizing symptoms. Peer victimization was associated with increased emotion dysregulation over a 4-month period. Increases in emotion dysregulation mediated the relationship between relational and reputational, but not overt, victimization and changes in internalizing symptoms over a 7-month period. Evidence for a reciprocal relationship between internalizing symptoms and relational victimization was found, but emotion dysregulation did not mediate this relationship. The implications for preventive interventions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

When girls versus boys play alone: Nonsocial play and adjustment in kindergarten.

The goal of the present study was to examine the relations between different forms of children's nonsocial play behaviors and adjustment in kindergarten. The participants in this study were 77 kindergarten children (38 boys, 39 girls; mean age?=?66.16 months, SD?=?4.11 months). Mothers completed ratings of child shyness and emotion dysregulation. Children's nonsocial play behaviors (reticent, solitary-passive, solitary-active) were observed during free play. In addition, teachers rated child behavior problems (internalizing and externalizing) and social competence; academic achievement was assessed through child interviews. Results from regression analyses revealed that different types of nonsocial play were differentially associated with child characteristics and indices of adjustment. For some forms of nonsocial play, the nature of these associations differed significantly for boys and girls. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Maltreatment, competency deficits, and risk for academic and behavioral maladjustment.

Maltreatment was predicted to negatively affect children's academic and behavioral adjustment through the creation of deficits in academic engagement, social competencies, ego resiliency, and ego control. Teachers' comprehensive evaluations, school records, and camp counselors' ratings were obtained for 229 socioeconomically disadvantaged children (ages 5–12 years), 146 of whom had been maltreated. Maltreated children showed less academic engagement, more social skills deficits, and lower ego resiliency than nonmaltreated comparison children. Maltreated children manifested multiple forms of academic risk and showed more externalizing and internalizing behavior problems. The effects of maltreatment on academic maladjustment were partially mediated by academic engagement, whereas maltreatment's effects on behavior problems were mediated fully by social competencies and ego resiliency.

Social functioning and adjustment in Canadian-born children with Chinese and European backgrounds.

The purpose of the study was to examine social functioning and adjustment in peer context in Chinese Canadian and European Canadian children. A sample of elementary school children participated in the study. Data on social functioning, peer acceptance and rejection, and victimization were collected from peer assessments and sociometric nominations. The results indicated that Chinese Canadian children were viewed by peers as less aggressive-disruptive than European Canadian children. Chinese Canadian girls, but not boys, were more shy-sensitive than their European Canadian counterparts. Sociability was associated with peer acceptance, whereas aggression was associated with peer rejection and victimization. Shyness was associated with peer relationship difficulties more evidently in European Canadian children than in Chinese Canadian children. These results indicate the relevance of ethnic background to children's peer social experiences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The significance of cross-racial/ethnic friendships: Associations with peer victimization, peer support, sociometric status, and classroom diversity.

This short-term longitudinal study examined the associations between cross-racial/ethnic friendships and relative changes in forms of peer victimization or peer support and the roles of classroom diversity and sociometric status (i.e., social preference) in these associations. A total of 444 children (age range: 9–10 years) from racially/ethnically diverse elementary schools participated in this study. Results demonstrated that cross-racial/ethnic friendships (but not same-racial/ethnic friendships) uniquely predicted relative decreases in relational victimization. Further, classroom diversity moderated the relations of cross-racial/ethnic friendships with relative decreases in physical victimization and relative increases in peer support, such that these relations were stronger for children in highly diverse classrooms. Finally, social preference mediated the association between cross-racial/ethnic friendships and relative decreases in relational victimization. The associations among cross-racial/ethnic friendships, same-racial/ethnic friendships, social experiences with peers, and classroom diversity are discussed.

Gender differences in ADHD: a meta-analysis and critical review

OBJECTIVE: To quantitatively review and critically evaluate literature examining gender differences in attention-deficit hyperactivity disorder (ADHD). METHOD: A meta-analysis of relevant research based on 18 studies meeting inclusion criteria was performed. Domains evaluated included primary symptomatology, intellectual and academic functioning, comorbid behavior problems, social behavior, and family variables. RESULTS: Gender differences were not found in impulsivity, academic performance, social functioning fine motor skills, parental education, or parental depression. However, compared with ADHD boys, ADHD girls displayed greater intellectual impairment, lower levels of hyperactivity, and lower rates of other externalizing behaviors; it was not possible to evaluate the extent to which referral bias affected these findings. Some gender differences were clearly mediated by the effects of referral source; among children with ADHD identified from nonreferred populations, girls with ADHD displayed lower levels of inattention, internalizing behavior, and peer aggression than boys with ADHD, while girls and boys with ADHD identified from clinic-referred samples displayed similar levels of impairment on these variables. CONCLUSIONS: The need for future research examining gender differences in ADHD is strongly indicated, with attention to methodological limitations of the current literature, including the potential confounding effects of referral bias, comorbidity, developmental patterns, diagnostic procedures, and rater source.     

Peer victimization and academic achievement in a multiethnic sample: The role of perceived academic self-efficacy.

This study examines the link between perceived peer victimization and academic adjustment in an ethnically diverse sample of 1,895 Grade 6 students nested within 108 school classes. It was hypothesized that students' academic self-efficacy mediates the (negative) link between victimization experiences and academic achievement outcomes. Multilevel analyses were used to test this hypothesis and to explore whether there are differences between ethnic minority and majority group children. Results indicated that peer victimization was negatively associated with both relative class-based, and absolute test-based measures of academic achievement. These associations were similar across different school classes. As expected, the link between victimization and achievement was mediated by perceived academic self-efficacy, suggesting that victimized students did less well academically because they considered themselves to be less competent. The lower perceived self-efficacy of victimized children could be partly attributed to lower global self-esteem and depressed affect. Results were largely similar for ethnic minority and majority group children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Examining student responses to frequent bullying: A latent class approach.

Bullying is a major concern in schools, yet there has been limited research examining the ways in which students respond to frequent victimization by their peers. The current study explored whether there are discrete groups of children who display similar patterns of responses to frequent bullying. We also examined the associations between the patterns of responding, characteristics of the victimization (form, chronicity, and perpetration of bullying), and co-occurring internalizing and externalizing symptoms. Latent class analysis regarding response strategies was conducted on data from 4,312 frequently victimized middle and high school students. The results revealed 4 common patterns of responses, including passive/low, active/support-seeking, aggressive and an undifferentiated/high pattern. The patterns of responses were differentially related to internalizing and externalizing symptoms, such that the children with the undifferentiated/high pattern were most likely to experience social–emotional problems and were more likely to experience indirect forms of victimization. Implications for future research on interventions with victimized children are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

A multivariate model of gender differences in adolescents' internalizing and externalizing problems.

Gender differences observed in interpersonal and self-critical vulnerabilities, reactivity to stressful life events, quality of relationships, and self-concepts inform a multivariate theoretical model of the moderating effects of gender on internalizing and externalizing problems in adolescence. To test this model, data were collected in a 1-year prospective study from an ethnically diverse sample of 460 middle school students. Increases in girls' internalizing symptoms, compared with boys', were partly explained by greater stability in girls' interpersonal vulnerabilities and greater magnitude in coefficients linking girls' relationships with parents and peers and internalizing problems. Boys' risks for externalizing problems, compared with girls', were partly explained by the greater stability in boys' vulnerability to self-criticism. Coefficients for most pathways in the model are similar for boys and girls. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Correlates of victimization in Chinese children's peer groups.

This study reports a cross-sectional investigation of the behavioral and academic correlates of victimization in Chinese children's peer groups. The participants were 296 children (161 boys and 135 girls; mean age?=?11.5 years) from Tianjin, China. Multi-informant assessments (peer nominations, teacher ratings, and self-reports) of peer victimization, aggression, submissiveness-withdrawal, assertiveness-prosociability, and academic functioning were obtained. Structural equation models indicated that peer victimization was associated with poor academic functioning, submissive-withdrawn behavior, aggression, and low levels of assertive-prosocial behavior. These findings suggest that there is considerable similarity in the social processes underlying peer group victimization across Chinese and Western cultural settings.
