The bidirectional relationship between peer relationships and bullying: Evidence from cross-lagged analyses among Chinese children.

BACKGROUND: In the digital age, bullying manifests in two distinct forms: traditional bullying and cyberbullying. Children's peer relationships are important predictors of bullying, and bullying in turn predicts peer relationships. However, few researchers have noted the bidirectional relationship between peer relationships and bullying. METHODS: The present study used a two-wave cross-lagged longitudinal design to fill this gap. The potential sex differences were also examined in this relationship. The sample consisted of 527 Chinese children aged 8 to 12 years (M = 9.69, SD = .96; 53.5% female). Participants completed peer nominations for peer acceptance, peer rejection and social dominance, as well as self-reports of traditional bullying and cyberbullying. RESULTS: Results showed that peer rejection at the first time point (T1) significantly and positively predicted traditional bullying perpetration, cyberbullying perpetration and cyberbullying victimization at the second time point (T2). Traditional bullying victimization at T1 significantly and negatively predicted peer acceptance and social dominance at T2. The results also revealed significant male and female differences. For instance, among boys, peer acceptance at T1 significantly and negatively predicted cyberbullying victimization at T2. In contrast, this relationship was not observed among girls. The present findings have important implications for understanding the cyclical relationship between peer relationships and bullying and providing practical guidance for improving peer relationships and reducing bullying.

Potential Mechanism Linking Peer Relationships and Adolescent Prosocial Behavior: Mediation of Cognitive Empathy and Moderations of OXTR and DRD2.

Peers are important socializers of adolescent prosocial behavior. Still, the proximal cognitive and emotional process underlying this link and the sources of individual differences in sensitivity to peer influence have yet to be explored. Utilizing the gene-gene-environment (G × G × E) approach and multi-informant measurement, this study investigated how peer relationships operate to influence adolescent prosocial behavior by examining the mediating role of cognitive and emotional empathy, and the moderating role of the OXTR and DRD2 genes. The study utilized longitudinal data from a community sample of Chinese adolescents (N = 1080, Mage = 13.32 years at T1). Results showed that cognitive empathy rather than emotional empathy mediated the link between peer acceptance/rejection and prosocial behavior. Furthermore, the association among peer acceptance, cognitive empathy, and prosocial behavior was moderated by OXTR and DRD2. Specifically, adolescents with the combinations of AA/AA or G/G genotypes of OXTR/DRD2 benefited more from peer acceptance compared to their counterparts carrying other combined genotypes. The findings highlight cognitive empathy as a proximal process linking peer interaction to prosocial behavior and lend support to the interaction between oxytocinergic and dopaminergic systems on environmental sensitivity.

Bullying perpetration and social status in the peer group: A meta-analysis.

INTRODUCTION: Associations between bullying perpetration and social status vary, not only between different facets of social status but also between bullying in primary versus secondary school. The main aim of the present study was to meta-analyse existing evidence regarding the prospective associations between bullying perpetration and various facets of social status, that is, popularity, peer acceptance, peer rejection, and social preference. METHODS: Electronic databases were searched to identify studies on bullying perpetration and later social status published up to January 17, 2022. Multilevel random effects models were performed using Metafor and differences in effect sizes as a function of substantive and methodological moderators were tested. RESULTS: In total, 116 effects were included from 18 publications, reporting on 17 different samples and more than 15,000 participants (mean age bullying assessment = 11.57 years, on average 51% female participants). Most samples were from the United States (7) or Europe (7). Overall, bullies were more popular, but also more rejected and scored lower on social preference compared with non-bullies. These associations remained when effects were adjusted for previous social status and other confounders. No link between bullying perpetration and acceptance was found. There was little evidence that effect sizes differed as a function of moderators. CONCLUSIONS: Bullies become more popular over time, but also have a higher risk of being rejected and being less socially preferred. Bullying perpetrators are more popular but also more rejected by their peers. There is no evidence that these links differ depending on sex or age at which perpetrators bully, reporter or type of bullying.

Lunchroom-Specific Peer Acceptance and Children's Internalizing Symptoms.

Prior research suggests the elementary school lunchroom is an important context for children's social development. Using a sample of 659 fourth-grade students in 10 public schools (50.7% female; 42.7% Hispanic/Latinx, 30.3% White, 10% Pacific Islander, 7.8% bi/multiracial, 2.2% American Indian, 2.2% Black, 1.9% Asian, and 2.9% other), we examined the association between lunchroom-specific peer acceptance and internalizing symptoms (i.e., depression and social anxiety symptoms). We hypothesized that lunchroom peer acceptance would predict self-rated depression and social anxiety symptoms when controlling for social preference scores. Using hierarchical linear modeling, results indicated self-rated lunchtime peer acceptance scores in December significantly predicted depression symptoms in May when controlling social preference scores and accounted for changes in depression scores across a school year. However, some significant gender differences emerged. Results suggest that elementary school lunchroom interventions should attend to children's perceptions of lunchroom likability and their experiences of depression symptoms.

Connecting the dots: social networks in the classroom and white matter connections in the brain.

BACKGROUND: Peer connections in school classrooms play an important role in social-emotional development and mental health. However, research on the association between children's peer relationships and white matter connections in the brain is scarce. We studied associations between peer relationships in the classroom and white matter structural connectivity in a pediatric population-based sample. METHODS: Bullying and victimization, as well as rejection and acceptance, were assessed in classrooms in 634 children at age 7. White matter microstructure (fractional anisotropy (FA), mean diffusivity (MD)) was measured with diffusion tensor imaging at age 10. We examined global metrics of white matter microstructure and used Tract-Based Spatial Statistics (TBSS) for voxel-wise associations. RESULTS: Peer victimization was associated with higher global FA and lower global MD and peer rejection was associated with lower global MD; however, these associations did not remain after multiple testing correction. Voxel-wise TBSS results for peer victimization and rejection were in line with global metrics both in terms of direction and spatial extent of the associations, with associated voxels (pFWE <.05) observed throughout the brain (including corpus callosum, corona radiata, sagittal stratum and superior longitudinal fasciculi). CONCLUSIONS: Although based only on cross-sectional data, the findings could indicate accelerated white matter microstructure maturation in certain brain areas of children who are victimized or rejected more often. However, repeated measurements are essential to unravel this complex interplay of peer connections, maturation and brain development over time.

Bidirectional Associations of Prosocial Behavior with Peer Acceptance and Rejection in Adolescence.

As most studies on the link between peer status and prosocial behavior are cross-sectional, conducted with children, and operationalize status as the difference between acceptance and rejection, it remains unclear whether peer acceptance and rejection are consequences or prerequisites of prosocial behavior in adolescence. To fill this gap, this study examines the bidirectional associations of prosocial behavior with peer acceptance and peer rejection with data collected at 3 time points, 6 months apart, in a sample of 660 early Chilean adolescents (M = 12.94, SD = 0.62; 55.1% boys). Cross-lagged panel analyses showed that prosocial behavior positively predicted future peer acceptance, whereas peer acceptance had no significant effect on future prosocial behavior. The association between rejection and prosocial behavior was negative and bidirectional between Time 1 and Time 2. When a new academic year began, between Time 2 and Time 3, prosocial behavior negatively predicted rejection, whereas rejection in the previous grade level was positively associated with prosocial behavior at the beginning of the next grade. Multi-group panel analyses did not detect significant differences between boys and girls in the cross-lagged associations of prosociality with peer acceptance and peer rejection. The results suggest that acting prosocially can make adolescents better liked by their peers and highlight the possible importance of the transition to a new academic year for the prosocial behavior of previously rejected students. Implications for future research on peer relations are discussed.

Disaggregating the Between-Person and Within-Person Associations Between Peer Acceptance and Academic Achievement in Early Elementary School.

We examined the between-person and within-person associations between peer acceptance and academic achievement in early elementary school years. Drawing on a sample of 784 academically at-risk students, the random intercept cross-lagged panel model was implemented to disaggregate the between- and within-person associations between peer acceptance and academic achievement from Grades 1 to 3. Academic achievement was measured using standardized achievement tests and teacher reports. Peer acceptance was measured using sociometric ratings. Positive associations between peer acceptance and academic achievement were found at the between-person level. At the within-person level, peer acceptance was not associated with standardized achievement test scores, and it was negatively predicted by teacher-reported academic achievement. These findings reveal the heterogeneous associations between peer relation and academic achievement at different levels of analyses and highlight the importance of disaggregating the between- and within-person associations for a better understanding of the nature of this developmental relation.

Bullying Experiences and Nonsuicidal Self-injury among Chinese Adolescents: A Longitudinal Moderated Mediation Model.

Bullying experiences play an important role in non-suicidal self-injury (NSSI). However, little is known about how and in what conditions different bullying experiences (i.e., experiences of being pure bullies, pure victims, and bully-victims) may influence NSSI. Guided by the transactional model of development and the integrated model of NSSI, the current study investigated two potential mediators (i.e., peer acceptance and depressive symptoms) and one potential moderator (i.e., psychological resilience) of the relations between different bullying experiences and NSSI. Participants were 812 Chinese adolescents (43% female; Mage at Wave 1 = 13.15 years) from a two-wave longitudinal study with data spanning 1 year. The results show that all three types of bullying experiences can relate to a higher likelihood of NSSI through two indirect pathways: (a) lower peer acceptance to more depressive symptoms, or (b) more depressive symptoms. These indirect effects were weaker for adolescents with higher (versus lower) levels of psychological resilience. Moreover, when bully-victims were distinguished from pure bullies and pure victims and the unique effects for all three groups were tested, the direct and indirect effects were most evident among bully-victims. These findings imply that it is necessary to distinguish bully-victims from pure bullies and pure victims. The results indicate that NSSI may be effectively reduced if interventions focus on promoting peer acceptance and reducing adolescent depressive symptoms, particularly for bully-victims with lower levels of psychological resilience.

The social withdrawal and social anxiety feedback loop and the role of peer victimization and acceptance in the pathways.

Social withdrawal and social anxiety are believed to have a bidirectional influence on one another, but it is unknown if their relationship is bidirectional, especially within person, and if peer experiences influence this relationship. We investigated temporal sequencing and the strength of effects between social withdrawal and social anxiety, and the roles of peer victimization and acceptance in the pathways. Participants were 2,772 adolescents from the population-based and clinically referred cohorts of the Tracking Adolescents' Individual Lives Survey. Self- and parent-reported withdrawal, and self-reported social anxiety, peer victimization, and perceived peer acceptance were assessed at 11, 13, and 16 years. Random-intercept cross-lagged panel models were used to investigate within-person associations between these variables. There was no feedback loop between withdrawal and social anxiety. Social withdrawal did not predict social anxiety at any age. Social anxiety at 11 years predicted increased self-reported withdrawal at 13 years. Negative peer experiences predicted increased self- and parent-reported withdrawal at 13 years and increased parent-reported withdrawal at 16 years. In turn, self-reported withdrawal at 13 years predicted negative peer experiences at 16 years. In conclusion, adolescents became more withdrawn when they became more socially anxious or experienced greater peer problems, and increasing withdrawal predicted greater victimization and lower acceptance.

Bidirectional effects between expressive regulatory abilities and peer acceptance among Chinese adolescents.

The current study examined potential bidirectional effects between adolescents' expressive regulation (the ability to enhance and suppress overt emotional behavior in line with situational demands) and peer interactions via two experiments. Experiment 1 tested the hypothesis that adolescents' expressive regulation affects their social acceptance from peers. Participants (N = 147) were randomly divided into three conditions and watched video clips in which a same-sex partner differed in his or her levels of expressive enhancement and suppression abilities. Results showed that participants reported greater liking of the partner when he or she was able to flexibly enhance and suppress emotional expressions in line with situational demands compared with when either one of these abilities was impaired. Experiment 2 then examined whether peer rejection reduced participants' enhancement and suppression abilities. We manipulated participants' feelings of rejection through a virtual Cyberball game. Following this manipulation (N = 100; Inclusion vs. Exclusion), we tested participants' expressive enhancement and suppression abilities, as well as their natural expressivity, via an observational task. Peer exclusion resulted in lower levels of enhancement ability and natural expressive behaviors but did not impair suppression ability. The results of these experiments suggest that both expressive enhancement and expressive suppression are important for adolescents to obtain higher peer acceptance. In addition, peer exclusion also caused impairments in expressive regulation, specifically reduced enhancement abilities. In summary, these results evidenced the bidirectional effects between expressive regulation and peer acceptance.

Why are you so optimistic? Effects of sociodemographic factors, individual experiences, and peer characteristics on optimism in early adolescents.

OBJECTIVE: Although a growing body of research has confirmed the manifold advantages of being an optimist, only a limited body of previous research has addressed the antecedents of optimism in real-life situations. This study examined whether parental socioeconomic status (SES), age-salient experiences (i.e., doing well in school and perceiving acceptance from peers), and aspects of the student composition at school contribute to changes in the optimism of early adolescents. METHOD: We followed a large sample of German seventh graders (N = 7,272; 52.9% females; baseline Mage = 14.1) at two measurement points over a period of 5 months and estimated latent regression models. RESULTS: First, optimism showed medium-sized rank-order stability between both measurement points. Second, parental SES predicted changes in optimism, but this effect was fully mediated by age-salient experiences. Third, positive age-salient experiences (i.e., academic achievement and perceived peer acceptance) predicted positive changes in early adolescents' optimism. Fourth, our results suggested no effects of school peer composition. CONCLUSIONS: The findings broaden our current knowledge about antecedents of changes in optimism during early adolescence by highlighting the effects of positive age-salient experiences, namely, academic achievement and perceived acceptance from peers.

Peer Acceptance and Sexual Behaviors from Adolescence to Young Adulthood.

Well-liked adolescents are more likely than their peers to engage in sexual behaviors, which may place them at higher risk of negative outcomes such as sexually transmitted infections and unwanted pregnancy. Yet, little is known regarding whether peer acceptance in adolescence predicts sexual outcomes in young adulthood. Understanding developmental links between peer acceptance and sexual outcomes will inform theories of how peers affect health and can help identify targets for health promotion efforts. Using longitudinal sociometric data from 1878 participants in the PROSPER study (54% female, 82% White, mean age = 11.79 at baseline), the present research examined the association of adolescent peer acceptance, reported annually from grades 6-11, with adolescent and young adult sexual outcomes. Well-liked adolescents were more likely to have sexual intercourse by age 16. At age 19, well-liked individuals were more likely to have had sexual intercourse but were less likely to be diagnosed with a sexually transmitted infection. For boys but not girls, peer acceptance was linked to having more past year sexual partners in young adulthood. Adolescent peer acceptance was not associated with other young adult sexual outcomes, such as sex without a condom or casual sex. Overall, well-liked adolescents demonstrated healthy sexual development into young adulthood, despite a higher likelihood of sexual initiation early in adolescence. Findings demonstrate the importance of peer acceptance for healthy development into young adulthood and suggest that well-liked adolescents may be appropriate targets for peer-led sexual health education programs.

Peer Acceptance and Nonsuicidal Self-injury among Chinese Adolescents: A Longitudinal Moderated Mediation Model.

Peer relationship plays an important role in non-suicidal self-injury (NSSI). However, little is known about how and in what conditions peer relationship may influence NSSI. By integrating multiple theories (i.e., attachment theory, the emotional regulation model of self-compassion and NSSI, and the differential-susceptibility theory), the current study investigated two potential mediators (i.e., self-compassion and depressive symptoms) and one potential moderator (i.e., behavioral impulsivity) of the relation between peer acceptance and NSSI. Participants were 813 Chinese adolescents (43% female; Mage at Wave 1 = 13.15 years) from a two-wave longitudinal study with data spanning one year. The results revealed that the indirect pathways linking peer acceptance and NSSI were conditioned on the level of behavioral impulsivity. Specifically, for adolescents with lower levels of impulsivity, a higher level of peer acceptance was related to fewer depressive symptoms directly or indirectly through self-compassion; fewer depressive symptoms, in turn, were linked to fewer NSSI behaviors longitudinally. For adolescents with higher levels of behavioral impulsivity, peer acceptance was related to fewer NSSI behaviors only through self-compassion. Results indicate that increasing peer acceptance is important in reducing adolescent NSSI. Interventions designed to reduce adolescent NSSI may also be effective if they focus on promoting adolescent self-compassion, particularly for adolescents with higher levels of behavioral impulsivity.

Teacher Support, Peer Acceptance, and Engagement in the Classroom: A Three-Wave Longitudinal Study in Late Childhood.

Although research has examined the bivariate effects of teacher support, peer acceptance, and engagement, it remains unclear how these key classroom experiences evolve together, especially in late childhood. This study aims to provide a detailed picture of their transactional relations in late childhood. A sample of 586 children (M age = 9.26 years, 47.1% boys) was followed from fourth to sixth grade. Teacher support and engagement were student-reported and peer acceptance was peer-reported. Autoregressive cross-lagged models revealed unique longitudinal effects of both peer acceptance and teacher support on engagement, and of peer acceptance on teacher support. No reverse effects of engagement on peer acceptance or teacher support were found. The study underscores the importance of examining the relative contribution of several social actors in the classroom. Regarding interventions, improving both peer acceptance and teacher support can increase children's engagement, and augmenting peer acceptance can help to increase teacher support.

The Catechol-O-Methyltransferase and Dopamine Transporter Genes Moderated the Impact of Peer Relationships on Adolescent Depressive Symptoms: A Gene-Gene-Environment Study.

Behavioral genetics studies and new empirical evidence suggest that depression cannot simply be explained by the influence of single genes but that gene-gene-environment interactions are important to better understanding the etiology of depression. The present study investigated the main and interactive effects of COMT gene Val158Met polymorphism, DAT1 gene rs27072 polymorphism, and peer relationships (i.e., peer acceptance and rejection) on adolescent depressive symptoms. In a sample of 1045 Chinese Han adolescents (Mage = 12.34 ± 0.47 years, 50.1% girls), saliva samples, self-reported depressive symptoms and within-classroom peer nominations were collected. After controlling for gender, age, and SES, the three-way interaction of COMT, DAT1, and peer acceptance significantly concurrently predicted adolescent depressive symptoms. Adolescents with ValVal genotype of COMT and CC genotype of DAT1 were more sensitive to acceptance, compared to their counterparts carrying other combined genotypes. However, a similar three-way interaction was not significant in the case of peer rejection. Additionally, the split-half validation generally replicated these findings. More importantly, this study underscores complex polygenic underpinnings of depression and lends support for the gene-gene-environment interactions implicated in the etiology of depressive symptoms.

Family-Peer Linkages for Children with Intellectual Disability and Children with Learning Disabilities.

Family interactions are potential contexts for children with intellectual and learning disabilities to develop skillful social behaviors needed to relate effectively with peers. This study examined problem solving interactions within families of elementary school-age children (7-11 years) with intellectual disability (n = 37), specific learning disabilities (n =48), and without disabilities (n = 22). After accounting for group differences in children's behaviors and peer acceptance, across all groups, mothers' behaviors that encouraged egalitarian problem solving predicted more engaged and skillful problem solving by the children. However, mothers' controlling, directive behaviors predicted fewer of these behaviors by the children. Fathers' behaviors had mixed associations with the children's actions, possibly because they were reactive to children's unengaged and negative behaviors. For the children, greater involvement, more facilitative behaviors, and less negativity with their families were associated with greater acceptance from their peers, supporting family-peer linkages for children at risk for peer rejection.

Positively biased self-perceptions of peer acceptance and subtypes of aggression in children.

There is a growing body of research linking children's positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the "disputed overestimation hypothesis," which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children's peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications.

Positively Biased Self-Perceptions: Who Has Them and What are Their Effects?

This study examined demographic and social competency characteristics of children who hold overly-positive self-perceptions of their social acceptance (positive bias). The effects of holding positive bias on aggressive and depressive symptoms were examined in a sample that excluded children on the extreme negative end of the bias continuum. Measures of peer-rated and self-perceived acceptance were obtained for 366 children in the 3rd through 5th grades. Peer-rated aggressive behavior and self-reported depressive symptoms were also collected. Results demonstrated sex, ethnicity, and social preference were uniquely associated with positive bias. Positive bias was related to aggression beyond the effects of social preference. Positive bias was not related to depressive symptoms. This study clarified who is likely to hold positive bias and replicated findings that suggest positive bias is a risk factor for aggressive outcomes. The idea that positive bias is neither a risk nor protective factor for depressive symptoms is discussed.

A Survival Analysis of Adolescent Friendships: The Downside of Dissimilarity.

The present study examined whether adolescent friendships dissolve because of characteristics of friends, differences between friends, or both. Participants were 410 adolescents (201 boys, 209 girls; mean age = 13.20 years) who reported a total of 573 reciprocated friendships that originated in the seventh grade. We conducted discrete-time survival analyses, in which peer nominations and teacher ratings collected in Grade 7 predicted the occurrence and timing of friendship dissolution across Grades 8 to 12. Grade 7 individual characteristics were unrelated to friendship stability, but Grade 7 differences in sex, peer acceptance, physical aggression, and school competence predicted subsequent friendship dissolution. The findings suggest that compatibility is a function of similarity between friends rather than the presence or absence of a particular trait.

Direct and indirect relations between parent-child attachments, peer acceptance, and self-esteem for preschool children.

The present study aims to test Bowlby's suggestions concerning relations between the child's attachment quality with parents and subsequently constructed models of self-worth during early childhood. In most research on this question, attachment with mothers is considered in relation to self-worth but the child's attachment with fathers is not. Neither has the peer group been studied as an influence on child self-esteem, in the context of attachment research. This study addresses these relatively unstudied influences on child self-esteem. Attachment security to mother and father was measured by the Attachment Behavior Q-Set at two and half years of age. At five years of age social acceptance was measured using two sociometric techniques, and the self-esteem with the California Child Q-Sort. Our analyses indicated that security of the attachment to father and peer acceptance are both unique, significant predictors of the childrens' self-esteem. The security of the attachment to mother was also related to child self-esteem but did not emerge as a uniquely significant predictor. Peer acceptance appeared to moderate of the effect of the security of the attachment to father on the self-esteem of children. Our results extend the relatively sparse literature relating early attachments to self-esteem during early childhood.
