Maladaptive Peer Relationships and the Development of Relational and Physical Aggression During Middle Childhood

This study examined the unique roles of peer rejection and affiliation with aggressive peers in the development of relational and physical aggression in a sample of 979 2nd through 4th grade children. Information about target children and their best friends’ aggression and peer rejection was gathered via peer‐nominations when the majority of children were in the 3rd grade, and again approximately one year later. Friendships were identified by having target children nominate their three best friends in their classroom. Path analyses conducted with children who had at least one reciprocated friendship revealed that peer rejection and friends’ aggression predicted changes in target children's aggression; however, the patterns of relations varied by gender and form of aggression. Higher initial levels of rejection and friends’ relational aggression predicted increases in relational aggression among girls only, whereas rejection and friends’ physical aggression predicted increases in physical aggression among boys and girls. The significance of these results for the application of peer influence theories to relational aggression, and to females, is discussed.     

Anger Perception, Caregivers' Use of Physical Discipline, and Aggression in Children at Risk

We analyzed the relations between teacher reports of aggressive behaviors, caregiver reports of their use of physical discipline, anger perception accuracy, and anger perception bias in middle childhood and teacher reports of aggressive behaviors two years later in a sample of children from economically disadvantaged families (n =152). Fisher r‐to‐z analyses showed a gender difference in the relation between anger perception accuracy and aggressive behavior in third grade. For girls, anger perception accuracy was significantly negatively related to aggression, and for boys, there was no relation between anger perception accuracy and aggression. Hierarchical multiple regression analyses showed that third grade aggressive behavior, caregivers’ reports of their use of physical discipline, and anger perception bias were significantly positively related to teacher reports of aggressive behavior two years later after controlling for gender and anger perception accuracy.     

Peer Victimization: The Role of Emotions in Adaptive and Maladaptive Coping

Mediator models were examined in which children's emotional reactions to peer aggression were hypothesized to mediate their selection of coping strategies and subsequent peer victimization and internalizing problems. Self‐report data were collected from 145 ethnically diverse kindergarten through fifth grade children (66 females and 79 males) who attended a predominantly low‐ to middle‐class school. Hypothetical scenarios were used to assess children's anticipated responses to peer aggression. Victims reported more intense negative emotions (e.g., fear and anger) than did nonvictims. Fear emerged as a predictor of advice seeking which, in turn, predicted conflict resolution and fewer internalizing problems. Conflict resolution was associated with reductions in victimization. Anger and embarrassment predicted revenge seeking which, in turn, was associated with increases in victimization. Additional pathways predicting changes in peer victimization across a single academic year as a function of children's emotional and coping responses to peer abuse are discussed.     

Teacher–Child Relationship Quality and Children's Peer Victimization and Aggressive Behavior in Late Childhood

This investigation examines the extent to which characteristics of the teacher–child relationship (closeness, dependency, and conflict) are predictive of changes in children's peer victimization and aggressive behavior over the course of a school year. Relational and physical forms of victimization and aggression were studied, and changes in peer acceptance and number of friendships were tested as possible mediators. Longitudinal data from 410 fourth‐ and fifth‐grade students (193 boys; 217 girls) and their teachers (N = 25) were analyzed. Whereas dependency on the teacher predicted heightened victimization from peers, a close relationship with the teacher forecasted less physical aggression toward peers. Moreover, decreases in number of friendships partially mediated the link between dependency on the teacher and heightened relational victimization for boys. These findings have implications for understanding the continuing influence of teacher–child relationships on children's social development in late childhood and for identifying interpersonal risk factors associated with involvement in peer harassment.     

Theory of mind,gender, gains in friendships versus peer acceptance and anxious solitude from middle childhood through early adolescence

This investigation proposes that theory of mind (ToM) may be related more strongly to change in friendships than peer acceptance in late middle childhood through early adolescence, and examines the relation between ToM and anxious solitude. Fourth grade ToM was tested as a predictor of change in reciprocated friendships, peer acceptance, and anxious solitude from 4th to 7th grade, and, conversely, reciprocated friendships, peer acceptance, and anxious solitude in 3^rd grade were tested as predictors of 4th grade ToM. Gender moderation of these relations was evaluated. Participants were 688 American public-school children (51.5% girls), 193 of whom completed a ToM questionnaire in 4th grade. In 3rd–7th grade children and their peers reported reciprocated friendship, and peers reported peer acceptance and anxious solitude annually. A multi-group (gender split) autoregressive cross-lagged panel analysis modeled relations between ToM and reciprocated friendship, peer acceptance, and anxious solitude over time. Consistent with hypotheses, girls’ more advanced 4th grade ToM predicted incremental gains in their number of friendships two years later, but not their peer acceptance. In contrast, boys’ more advanced 4th grade ToM did not predict change in their number of friendships or peer acceptance over time. Gender differences in the relation between ToM and friendship are discussed in the context of gender-specific peer relations patterns in late middle childhood and early adolescence. Additionally, more advanced 4th grade ToM predicted gains in anxious solitude in middle school for both genders. This somewhat surprising result is discussed in relation to ToM assessment and peer relations in anxious solitary children.     

Gender Differences in Preschool Aggression During Free Play and Structured Interactions: An Observational Study

We observed 48 children from rural preschools (M=64 months old) in two different social contexts to test hypotheses about the type (relational, physical, verbal, nonverbal), contextual independence, and sociometry of girls’ and boys’ aggressive tactics. We predicted and generally found that (1) girls displayed more relational aggression than boys while boys displayed more physical and verbal aggression than girls, and that children received more physical and verbal aggression from male peers, and tended to receive more relational aggression from female peers, (2) behavioral observations of aggression corresponded with teacher reports of children's aggressive styles, (3) aggression observed during free play predicted children's aggressive styles in a structured setting at both the group and individual levels, and (4) aggressive tactics were associated with projected sociometric characteristics (dominance and peer acceptance).     

Social Competence with Peers in Third Grade: Associations with Earlier Peer Experiences in Childcare1

The early developmental antecedents of individual differences in children's social functioning with peers in third grade were examined using longitudinal data from the large‐scale National Institute of Child Health and Human Development (NICHD) study of early child care. In a sample of 1,364 children, with family and child factors controlled, the frequency of positive and negative peer interactions in childcare between 24 and 54 months and the number of hours spent in childcare peer groups of different sizes (alone, dyad, small, medium, large) predicted third graders' peer competence at three levels of analysis: individual social skills, dyadic friendships, and peer‐group acceptance. Children who had more positive experiences with peers in childcare had better social and communicative skills with peers in third grade, were more sociable and co‐operative and less aggressive, had more close friends, and were more accepted and popular. Children with more frequent negative experiences with peers in childcare were more aggressive in third grade, had lower social and communicative skills, and reported having fewer friends. When children spent more time in small‐sized peer groups in childcare (four or fewer children at 24 months of age up to seven or fewer at 54 months), they were more sociable and co‐operative in third grade, but their teachers rated them as more aggressive, suggesting that such children may be more socially outgoing and active both positively and negatively. Like those who spent more time in small peer groups, children who spent more hours in medium‐sized groups received higher ratings for peer aggression by their third‐grade teachers. Children who spent more time with one other child in childcare or in small peer groups had fewer classroom friends in third grade as reported by the teacher but not according to maternal report or self‐report. There were no significant associations between the amount of time children spent in large childcare‐based peer groups and third‐grade peer social competence.     

Predicting the development of dependency on the teacher in late childhood: The role of peer victimization and peer beliefs

Evidence indicates that being overly dependent on the teacher places children's academic and socioemotional development at risk. However, little is known about what predicts dependency on the teacher or how the quality of interactions occurring within the classroom peer system may impact how children relate to their teacher the following school year. The current study tested the proposition that peer victimization may result in negative perceptions of classmates (i.e., peer beliefs), leading to overreliance on teachers. Data were collected from 365 children in the fall and spring of their third/fourth grade year and the fall of their fourth/fifth grade year (195 girls; M_age = 8.92 years; 86.8% white). Peer-reports of peer victimization and self-reports of peer beliefs were collected at each wave of the study. Teacher-reports of dependency were collected in the fall of the first and second years of the study. Path analyses showed that for boys peer victimization directly predicted higher levels of dependency on the next year's teacher, and, for boys and girls, peer victimization indirectly predicted dependency through lower levels of prosocial peer beliefs. Supplemental analyses assessing teacher-child conflict and closeness confirmed that findings were unique to dependency. These results underscore how children's perceptions of their classmates may contribute to dependency in their relationships with teachers and highlight the need for further research into the transactional and cumulative impact of difficulties within peer and teacher relationships.     

Associations between sleep consolidation in infancy and peer relationships in middle childhood

Sleep plays an important role in many aspects of children's development. Research on children's sleep and their peer relationships has begun to emerge in the last years. However, these studies are mostly cross‐sectional. The current study aimed to investigate the associations between infant sleep and peer relationships in middle childhood. The sample comprised 72 children. Sleep was measured at 1 year using a sleep diary completed by mothers. In the second and third grades of elementary school (7 and 8 years of age), mothers and fathers reported on their children's functioning with peers. When they were in third grade, children were interviewed regarding their friendship quality with a best friend. Results revealed negative associations between children's sleep consolidation (i.e., ratio of nighttime sleep) and parent‐reported peer problems, and positive associations between sleep consolidation and perceived friendship quality. These findings suggest that well‐regulated sleep in infancy may help children develop the skills necessary for later appropriate social functioning in peer contexts.     

Predictors of Peer Victimization among Urban Youth

This study examined aggression and withdrawal as predictors of peer victimization. In addition, peer rejection was evaluated as both a moderator and mediator of these relations. The sample consisted of 1956 African-American, Hispanic, and White elementary school-aged boys and girls attending urban and inner-city schools that were classified as high or moderate disadvantage. Correlation and regression analyses revealed that aggression predicted both contemporaneous and longitudinal victimization by peers. This relation maintained across school disadvantage, ethnicity, age, and sex, andwas mediated by rejection. Withdrawal, mediated by rejection, predicted victimization for fourth graders only; withdrawal also reduced risk for victimization for low rejected children. The implications for understanding the dynamics of childhood victimization and intervention are discussed.     

Aggressive and Prosocial Peer Group Functioning: Effects on Children's Social,School, and Psychological Adjustment

This study examined the effects of aggressive and prosocial contexts of peer groups on children's socioemotional and school adjustment. Data on informal peer groups, social functioning, and different aspects of adjustment were collected from multiple sources in a sample of elementary school children (149 boys, 181 girls; M age = 10 years). Multilevel analyses indicated that group aggressive and prosocial orientations made direct contributions to children's social, school, and psychological functioning. Group contexts also moderated the individual‐level relations between social behavior and self‐perceptions; prosocial behavior was associated with social or scholastic self‐perceptions more evidently in low prosocial and high aggressive groups. The results suggest that the peer group is an important context for children's performance and adjustment in various domains.     

Relational Aggression in Peer and Dating Relationships: Links to Psychological and Behavioral Adjustment

We examined the contribution of relational aggression in adolescents' peer and dating relationships to their psychological and behavioral adjustment. In the Fall and again four months later, 1279 (646 female) grade 9 students reported on relational aggression perpetration and victimization in their romantic and peer relationships, depression/anxiety symptoms (psychological adjustment) and delinquency (behavioral adjustment). Using hierarchical regression analyses, controlling for Time 1 adjustment/behavior, peer relational aggression perpetration predicted depression/anxiety. Dating relational victimization also predicted depression/anxiety, but only for girls. Furthermore, girls who were perpetrators of relational aggression in both peer and dating contexts were most likely to show increases in delinquent behavior. We conclude that dating and peer relationships are not redundant, but make independent and additive contributions to adolescent adjustment. Girls, in particular, may be at greatest risk for poor outcomes when they have relationally aggressive relationships. Results also highlight the need for greater awareness of the complexity and significance of adolescent dating relationships.     

The Role of Respect in the Relation of Aggression to Popularity

Can aggressive children be popular with peers? Generally, sociometric popularity (liking nominations) has been shown to be negatively associated with aggression, and perceived popularity (popularity nominations) has been shown to be positively associated with aggression. The thesis of the present research was that being respected by peers moderates the relation between aggression and popularity. For both third‐ through sixth‐grade boys (N = 107) and girls (N = 117), perceived popularity by peers was positively associated with nominations for aggression (both overt and relational) only for children high in respect. Aggression was negatively associated with sociometric popularity for girls who were low in respect; sociometric popularity for girls high in respect was not related to aggression nominations. In sum, aggressive children were considered to be popular only if they were respected; aggressive girls were not disliked if they were respected.     

Young Children's Prosocial and Aggressive Behaviors and Their Experiences of Being Targeted for Similar Behaviors by Peers

Children's target experiences (as recipients of prosocial peer acts and victims of peer aggression) were investigated for their concurrent and longitudinal associations with prosocial and aggressive behavior. Forty‐four children (initially 22–40 months) were observed in naturalistic interactions with peers during a two‐month period for each of three consecutive years. Results revealed no consistency over time in children's experiences as targets for aggressive or prosocial peer acts, although there was some indication that altruistic target experiences may be stable from the end of the preschool period. Early behavior appeared to affect the way children were later treated by peers, but no support was found for the idea that early target experiences influence later behavior. Prosocial behavior was concurrently and longitudinally associated with prosocial target experiences. Aggressive behavior reduced the likelihood of children being targets of prosocial peer behavior and, over time, also of their being targets of peers’ aggression.     

From Classroom to Dyad: Actor and Partner Effects of Aggression and Victim Reputation

This study examined whether early adolescents’ classroom aggression predicted their aggression in a one‐on‐one dyadic setting, and whether early adolescents’ classroom victimization predicted their victimization in the dyadic setting. After completing peer nominations for aggression and victimization, 218 early adolescents (M age = 11.0 years) participated in a dyadic paradigm in which they were led to believe that they played against a same‐sex classmate for whom they could set the intensity of noise blasts. Analyses with the actor–partner interdependence model by Olsen and Kenny showed that peer‐nominated physical aggression for boys and relational aggression for girls predicted noise blast aggression in the dyadic setting. For girls but not boys, peer‐nominated victimization predicted victimization in the dyadic setting.     

Children's Anger Attribution Bias: Relations to Family Environment and Social Adjustment

We examined the relations of caregiver depression and family instability to preschool children's anger attribution bias and emotion attribution accuracy on a test of emotion situation knowledge. After controlling for age, gender, and verbal ability, caregiver depression and family instability predicted children's anger attribution bias but not the overall accuracy of their emotion attributions. We also divided children into groups low and high on teacher reports of aggression and groups low and high on teacher reports of peer rejection and examined the anger attribution bias of these groups. For boys but not girls, greater anger attribution bias predicted higher levels of aggression. For all children, greater anger attribution bias predicted higher levels of peer rejection. Results suggest that the misattribution of anger to others may be an important component of some children's early emotional and social difficulties.     

Can Both Low and High Self‐esteem Be Related to Aggression in Children?

This study examined the opposing hypotheses that either low or exaggerated but disputed self-esteem is related to aggression in 652 12-year-old schoolchildren. Children provided peer nominations of social acceptance and of physical aggression, self-ratings of global self-worth and of social satisfaction. Teachers rated aggressive behavior and internalizing problems. Exaggerated but disputed self-esteem was conceptualized as discrepancies between self and peer evaluations of social satisfaction and of social acceptance, respectively, in combination with peer rejection. The main results showed that both low levels of global self-worth and exaggerated but disputed self-esteem were related to aggression. The findings indicated that, depending on how self-esteem is conceptualized, aggressive children may appear to have both a low and a high self-esteem. Regarding gender differences, exaggerated self-esteem was more strongly related to aggression in boys than in girls.     

Links between friends’ behaviors and the emergence of leadership in childhood: A genetically informed study of twins

Using a genetically informed design, this study examined whether children's leadership behavior varied as a function of their reciprocal friends’ behavioral characteristics. Specifically, we tested (a) whether friends’ use of a dual strategy (specifically, indirect aggression with prosocial behavior) was associated with children's leadership behavior and (b) whether, in line with a gene‐environment interaction (GxE), the predictive association between friends’ behaviors and children's leadership behavior varied depending on the child's genetic likelihood for leadership. The sample comprised 239 Monozygotic and same‐sex Dizygotic twin pairs (50% boys) assessed in grade 4 (mean age = 10.4 years, SD = 0.26). Reciprocal friendship and children's and their friends’ prosocial, indirectly aggressive, and physically aggressive behaviors were measured via peer nominations. Children's and friends’ leadership was measured through teacher ratings. Multilevel regression analyses revealed that children's genetic likelihood for leadership was positively associated with their leadership behavior. Moreover, the higher their genetic likelihood for leadership, the more children displayed increased leadership behavior when friends showed a combination of indirect aggression and prosocial behavior (GxE). These results underline the role of friends’ behaviors in explaining children's leadership. Socializing with bistrategic friends seems to foster leadership skills especially in children with a genetic likelihood for leadership.     

Is preventing peer victimization sufficient? The role of prosocial peer group treatment in children's socioemotional development

Despite extensive research on the harmful effects of peer victimization, little is known about whether prosocial treatment from peers contributes to healthy socioemotional development. To address this issue, 366 third and fourth graders (170 boys; M _age = 9.34) were followed over three time points. Children completed measures of prosocial peer treatment, peer victimization, depressive affect, and friendship quality. Teacher‐reports of depressive affect and peer‐reports of aggression, victimization, and friendships were also obtained. Controlling for peer victimization, number of friends, and friendship quality, prosocial peer treatment negatively predicted depressive affect. For boys, prosocial peer treatment mediated the association between victimization and teacher‐reported depressive affect. These findings underscore the importance of prosocial peer group treatment and the need to broaden the goals of anti‐bullying interventions to include the promotion of positive peer interactions.     

Prospective Associations between Peer Aggression and Victimization: The Moderating Roles of Physiological Stress Reactivity and Gender

The present investigation examined whether heightened skin conductance reactivity (SCLR) to peer stress strengthened the prospective associations between physical and relational aggression and victimization, and whether associations were stronger for physical forms of aggression and victimization among boys and relational forms of aggression and victimization among girls. A total of 91 children [M age = 10.18 years, standard deviation (SD) = .68] were assessed twice over 1 year. At the first assessment, SCLR in response to recounting a relational stressor (e.g., exclusion; SCLR‐R) and an instrumental stressor (e.g., property theft; SCLR‐I), and teacher‐reported aggression were measured. Parents reported on child victimization at both time points. Among youth with heightened SCLR‐I, physical aggression was associated with increases in physical victimization for boys and decreases in physical victimization for girls. Among youth with heightened SCLR‐R, relational aggression was associated with increases in physical victimization for girls only. Results were largely consistent with the hypothesis that aggressors with a propensity to exhibit negative displays of emotion, as indexed by heightened sympathetic nervous system (SNS) reactivity to peer stress, may be especially likely to suffer peer victimization. Gender‐specific effects highlight the importance of including both physical and relational forms of aggression and victimization to capture victimization risk among aggressive boys and girls.
