Peer victimization, posttraumatic stress symptoms, and chronic pain: A longitudinal examination

Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10-18 years recruited from a tertiary level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. Pain was re-assessed at 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference, while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.

Peer Victimization and Adolescent Mental Health: School-level Victimization as a Moderator

As a global issue, peer victimization is closely associated with adolescent mental health. Although previous research has explored the relationship between peer victimization and mental health in some contexts, the school context, particularly within the Chinese cultural context, has not received sufficient attention. Based on the Healthy Context Paradox, this study aimed to explore the moderating role of school-level victimization in the relationship between individual-level peer victimization and mental health. This study tested two hypotheses by using a multilevel design: higher individual-level and school-level peer victimization are associated with higher depressive symptoms and lower life satisfaction (Hypothesis 1); school-level victimization moderates the association between individual-level peer victimization and mental health (Hypothesis 2). Participants were 39,720 adolescents (50.41% females; Mage = 13.68, SD = 2.39) across 292 Chinese schools. They completed a set of questionnaires, including the Center for Epidemiologic Studies Depression Scale, the single-item Life Satisfaction Questionnaire, the Peer Victimization Scale, and demographics. The multilevel model indicated that both individual-level and school-level peer victimization were positively correlated with depressive symptoms and negatively correlated with life satisfaction. In schools with lower levels of victimization, there was a stronger association between individual peer victimization and adolescent mental health. A potential explanation for these results might be the victimization visibility and perceived severity in different contexts. These findings extended the discussion of the Healthy Context Paradox within the Chinese school context and provided valuable insights for developing school support strategies for victimized adolescents. School management might play a significant role in affecting the mental health of victimized adolescents.

Bidirectional Longitudinal Associations between Parental Psychological Control and Peer Victimization among Chinese Adolescents: The Mediating Role of Basic Psychological Need Satisfaction

Despite evidence indicating a connection between inappropriate parenting styles and peer victimization, the dynamic processes and mechanisms underlying this link and whether it is consistent across genders and different developmental stages have yet to be explored. To address these gaps, the current 2-year longitudinal study explored the potential bidirectional associations between parental psychological control and peer victimization, as well as the mediating role of adolescent basic psychological need satisfaction. A total of 4,990 adolescents (49.4% boys, Mage T1 = 12.21 years, SDage T1 = 2.60) across different developmental stages (early adolescents, N = 1,819, 49.2% boys, Mage T1 = 9.34 years, SDage T1 = 0.62; middle adolescents, N = 1,525, 50.75% boys, Mage T1 = 12.47 years, SDage T1 = 0.69; late adolescents, N = 1,646, 46.5% boys, Mage T1 = 15.26 years, SDage T1 = 0.50) participated in this three-wave longitudinal survey. The results revealed that parental psychological control was bidirectionally associated with peer victimization. Additionally, basic psychological need satisfaction played the meditating role in this vicious cycle. Further analysis demonstrated interesting developmental differences. Parental psychological control was directly associated with subsequent peer victimization at all three developmental stages, and peer victimization was only directly associated with subsequent parental psychological control in the next year among early adolescents and middle adolescents. The mutual mediating role of basic psychological need satisfaction between parental psychological control and peer victimization was observed exclusively in early adolescents. Both male and female adolescents could be equally affected by these dynamics. This research underscores the reciprocal dynamics inherent in parent-child interactions, intervening in either of these processes (i.e., family, peers, and adolescent basic psychological need satisfaction) may break this destructive cycle.

The Protective Roles of Self-Compassion and Parental Autonomy Support Against Depressive Symptoms in Peer-Victimized Chinese Adolescent Girls: A Longitudinal Study

Peer victimization (PV) is a common and serious problem in school contexts, which hinders adolescents' emotional development and social adaptation. The present study aimed to test the longitudinal relationship between PV and the increase of depressive symptoms (DSs) among Chinese mid-late adolescents using a two-wave longitudinal design and examine the buffering effects of self-compassion (SC) and parental autonomy support (PAS) on this relationship. A relatively large sample of Chinese high school students (N = 722, 52.1% boys; age at Time 2 = 16.23 years old, SD = 0.79) were surveyed annually at two time points. The results showed that PV at Time 1 positively predicted DSs at Time 2 after controlling for the DSs at Time 1. In addition, SC and PAS moderated the longitudinal relationship between PV and the development of DSs, while such moderating effects only existed in girls but not in boys. Specifically, the positive relationship between PV and DSs was non-significant among girls with higher levels of SC or PAS. Our findings highlighted that SC and PAS might be important protective factors buffering against DSs for victimized girls.

Companion animals and the relationship between peer victimization and emotion regulation in youth

Peer victimization can negatively impact emotion regulation in youth and is associated with harmful mental health outcomes. One protective factor against the impacts of peer victimization is a strong attachment to family and positive peer relationships. Given that pets are commonly seen as family members and that youth report turning to their pet for emotional comfort, companion animals could provide an avenue of support for youth experiencing victimization. A geographically diverse sample of 5725 adolescents in the United States from the Adolescent Brain Cognitive Development (ABCD) Study® was used to explore whether the relationship between peer victimization and emotion regulation was moderated by whether a pet lives in the home. Having a pet in the home did not moderate the relationship between peer victimization and emotion regulation; however, mean-level differences were present across types of household pet (i.e., youth with no pets, youth with at least one dog, and youth with non-dog pets). Participants who did not live with a companion animal showed higher levels of both maladaptive emotion regulation (expressive suppression) and adaptive emotion regulation (cognitive reappraisal), suggesting that having a pet might lower overall emotion regulation pathways regardless of adaptive directionality. Relational victimization was a significant predictor of expressive suppression regardless of whether there was a pet in the home, although overt victimization was not a predictor of either kind of emotion regulation. This research demonstrates the complex nature of human-animal relationships and suggests more research is needed to understand the nuanced relationship between pets, peer victimization, and emotion regulation.

Decoding the effects of varied peer victimization forms on depression and anxiety among Chinese adolescents: An exploration through latent transition analysis

This study aims to examine co-occurrence patterns of depression and anxiety among Chinese adolescents and their associations with various forms of peer victimization. We collected longitudinal data from 1005 middle school students using the Multidimensional Peer Victimization Scale, Center for Epidemiological Studies Depression Scale, and State-Trait Anxiety Inventory. Then we conducted latent profile analysis, latent transition analysis, and logistic regression analysis. The results reveal the presence of three depression-anxiety profiles among participants: low depression-anxiety group, moderate depression-anxiety group, and high depression-anxiety group. As verbal and relational victimization increase, adolescents are more likely to transition to a higher level of depression-anxiety profile. However, an increase in physical and property victimization predicts a transition to a lower level of depression-anxiety profile. The diverse effects resulting from different forms of victimization exhibit gender differences. For boys, an increase in relational victimization made participants in the moderate depression-anxiety group more likely to transition to the high depression-anxiety group, whereas this effect was not significant among girls. This study is theoretically significant for understanding the link between depression, anxiety, and their influencing factors. It suggests that educators, while addressing verbal and relational harm in adolescents, should reconsider the potential impact of physical and property harm. Opportunities to transform negative events into positive ones should be explored. Educators should tailor their focus based on gender, with a particular emphasis on addressing relational harm among male students. This underscores the need for differentiated approaches to effectively support students.

Temporal relation between pubertal development and peer victimization in a prospective sample of US adolescents

Peer victimization typically peaks in early adolescence, leading researchers to hypothesize that pubertal timing is a meaningful predictor of peer victimization. However, previous methodological approaches have limited our ability to parse out which puberty cues are associated with peer victimization because gonadal and adrenal puberty, two independent processes, have either been conflated or adrenal puberty timing has been ignored. In addition, previous research has overlooked the possibility of reverse causality-that peer victimization might drive pubertal timing, as it has been shown to do in non-human primates. To fill these gaps, we followed 265 adolescents (47% female) prospectively across three-time points (Mage : T1 = 9.6, T2 = 12.0, T3 = 14.4) and measured self-report peer victimization and self- and maternal-report of gonadal and adrenal pubertal development on the Pubertal Development Scale. Multilevel modeling revealed that females who were further along in adrenal puberty at age 9 were more likely to report peer victimization at age 12 (Cohen's d = 0.25, p = .005). The relation between gonadal puberty status and peer victimization was not significant for either sex. In terms of the reverse direction, the relation between early peer victimization and later pubertal development was not significant in either sex. Overall, our findings suggest that adrenal puberty status, but not gonadal puberty status, predicted peer victimization in females, highlighting the need to separate gonadal and adrenal pubertal processes in future studies.

Preschool Aggression and Victimization: A Short-Term Longitudinal Analysis of the Immediate Social Environment

Introduction

Preschool aggression, a significant concern, requires an in-depth examination beyond individual factors. This study explored the link between individual characteristics, immediate social environment variables, and the likelihood of preschoolers being nominated as aggressors or victims. The novelty of the study lies in its comprehensive longitudinal examination, using a multi-informant approach, of how family dynamics, peer relations, teacher-child interactions, and community factors are related to preschool aggression within the context of Bronfenbrenner's ecological system theory.

Methods

Data was collected at two points, four months apart, to investigate the interplay among sociodemographic, individual, family, and school factors and subsequent child aggression. The study included 394 children (184 girls, 210 boys), aged 3 to 6 years (M = 4.36, SD = 0.87). Caregivers completed questionnaires on socioeconomic status, community relationships, children's emotional regulation, and family functioning. Teachers rated closeness with each child, while children nominated liked and disliked peers, as well as those exhibiting aggressive or victimized behaviour.

Results

Logistic regression models revealed stronger associations between peer aggression and victimization and individual factors over microsystems. Surprisingly, community cohesion showed a robust positive link with an increased likelihood of children being nominated as victims, challenging the assumption that positive parenting practices and strong community cohesion always leads to positive outcomes for individuals.

Discussion

The study advances theoretical understanding by examining how factors within preschoolers' microsystems influence aggressive behaviors, contributing to more holistic models for addressing preschool aggression and victimization in schools. The findings highlight the significance of targeted interventions, emphasizing early identification of aggression or victimization signs and customized programs for social and emotional skill development. Addressing parental stress and interparental conflict is crucial. Additionally, community-based initiatives, like strengthening support networks, play a pivotal role in fostering healthier social dynamics among preschoolers.

Longitudinal study of peer victimization, social support, and mental health during early adolescence

BACKGROUND

Peer victimization predicts the development of mental health symptoms in the transition to adolescence, but it is unclear whether and how parents and school environments can buffer this link.

METHODS

We analyzed two-year longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study, involving a diverse sample of 11 844 children across the United States (average at baseline = 9.91 years; standard deviation = 0.63; range = 8.92-11.08; complete case sample = 8385). Longitudinal associations between peer victimization and two-year changes in mental health symptoms of major depression disorder (MDD), separation anxiety (SA), prodromal psychosis (PP), and attention-deficit/hyperactivity disorder (ADHD) were examined including a wide range of covariates. Mixed linear models were used to test for the moderating effects of parental warmth and prosocial school environment.

RESULTS

20% of children experienced peer victimization. Higher exposure to peer victimization was associated with increases in MDD, SA, and ADHD symptoms. Parental warmth was associated with decreases in MDD symptoms but did not robustly buffer the link between peer victimization and mental health symptoms. Prosocial school environment predicted decreases in PP symptoms and buffered the link between peer victimization and MDD symptoms but amplified the link between peer victimization and SA and ADHD symptoms.

CONCLUSIONS

Peer victimization is associated with increases in mental health symptoms during the transition to adolescence. Parental warmth and prosocial school environments might not be enough to counter the negative consequences of peer victimization on all mental health outcomes.

Facing ambiguity: Social threat sensitivity mediates the association between peer victimization and adolescent anxiety

Peer victimization is a developmentally salient stressor that elevates adolescents' risk for anxiety disorders. However, modifiable mechanisms that explain this link and can be targeted via therapeutic interventions remain poorly understood. Drawing from psychobiological models implicating aberrant threat sensitivity in the development and maintenance of psychopathology, the current study investigated sensitivity to peer-related social threats as a mechanism underlying the association between peer victimization and anxiety. A sample of 197 dyads of early adolescents (M age = 12.02; 46% female) and parents/guardians (M age = 41.46; 90% female) completed online surveys assessing peer victimization, sensitivity to potential (i.e., ambiguous) social threats, and anxiety. Controlling for potentially confounding demographic and psychosocial factors, both self- and parent-reported peer victimization were positively associated with adolescent anxiety symptoms. Additionally, there were significant indirect effects from self- and parent-reported peer victimization to anxiety via social threat sensitivity. Supplemental analyses indicated unique effects of covert, but not overt, peer victimization on social threat sensitivity and anxiety. The findings provide initial evidence that peer victimization experiences lower adolescents' threshold for interpreting threats in ambiguous social situations, which contributes to heightened anxiety. These results implicate social threat sensitivity as a potential therapeutic target for interrupting links from peer victimization to psychological distress.

Emotional problems and peer victimization in adolescents born very preterm and full-term: Role of self-control skills in childhood

The aim of the current study was to examine whether self-control skills in childhood moderate the association between very preterm birth (<32 weeks of gestational age) and emotional problems and peer victimization in adolescence. We used data from four prospective cohort studies, which included 29,378 participants in total (N = 645 very preterm; N = 28,733 full-term). Self-control was mother-reported in childhood at 5-11 years whereas emotional problems and peer victimization were both self- and mother-reported at 12-17 years of age. Findings of individual participant data meta-analysis showed that self-control skills in childhood do not moderate the association between very preterm birth and adolescence emotional problems and peer victimization. It was shown that higher self-control skills in childhood predict lower emotional problems and peer victimization in adolescence similarly in very preterm and full-term borns.

Impacts of difficulties with emotion regulation on the longitudinal relationship between peer victimization and changes in adolescent nonsuicidal self-injury

INTRODUCTION

Research has found that peer victimization is associated with adolescent nonsuicidal self-injury (NSSI) behavior; however, most of these studies ignored the association between these constructs at the within-person level. Additionally, the association between peer victimization and NSSI may vary among adolescents with different personal characteristics. With a longitudinal design, this study investigated whether and how emotion regulation (ER) difficulties moderate the relationship between peer victimization and changes in NSSI, with particular attention given to the unique moderating role of different dimensions of ER difficulties.

METHODS

The study sample comprised 3,561 adolescents aged between 10 and 17 years old (Mage  = 13.22, SD = 0.85; 56.9% males). Self-report assessments were administered in December 2021 and June 2022 in Shanxi province, China.

RESULTS

The latent change score model showed that the adolescent NSSI increased during our assessments, with peer victimization as a significant predictor. ER difficulties moderated the association between peer victimization and NSSI changes, but interestingly, in an unexpected pattern. Specifically, peer victimization significantly predicted NSSI changes among adolescents with low ER difficulties but not for those with high ER difficulties. Moreover, among the multiple dimensions of ER difficulties, only nonacceptance of emotional responses and limited access to emotion regulation strategies interacted with peer victimization to predict NSSI changes and showed interaction patterns similar to those at the overall level of ER difficulties.

CONCLUSIONS

The current study revealed the moderating role of ER difficulties in the relationship between peer victimization and changes in NSSI. These findings provide intervention implications for adolescents who engage in NSSI.

Associations between forms of aggression and peer victimization: Does prosocial behavior matter?

Relatively little is known regarding factors that may mitigate the strength of the associations between forms of aggressive behavior and peer victimization. The goal of the current study was to investigate prosocial behavior as a moderator of these links over a 2-year period during middle childhood. Participants included 410 third-grade students (53% boys) and their homeroom teachers. Results indicated that prosocial behavior was associated with lower initial levels of victimization, whereas relational aggression was associated with higher initial levels of victimization. Physical aggression predicted more stable patterns of victimization over time, and prosocial behavior moderated the prospective link from relational aggression to peer victimization; specifically, relational aggression predicted decreases in victimization at higher levels of prosocial behavior and more stable patterns over time when levels of prosocial behavior were low. Further, gender differences were observed in the moderating effect of prosocial behavior on the prospective link from physical aggression to peer victimization, such that it served as a risk factor for boys and a protective factor for girls.

The effect of peer victimization on adolescents' revenge: the roles of hostility attribution bias and rumination tendency

Although previous studies revealed that peer victimization was closely related to revenge, mechanisms underlying this association have been unclear. The purpose of this study is to examine the mediating role of hostility attribution bias (HAB) and the moderating role of rumination tendency in the relationship between peer victimization and revenge. The data were collected from 6,622 adolescents. The PROCESS macro of SPSS 26.0 was used to examine the hypotheses. The results show that peer victimization positively associates with revenge. Hostile attribution bias play a partial mediating role between peer victimization and revenge. Both the direct effect of peer victimization on revenge and the first half of the mediating effect of HAB are moderated by rumination tendencies. Specifically, both direct and indirect effects of peer victimization on revenge are stronger in individuals with concrete experiential rumination (CER) tendency than in those with abstract analytic rumination (AAR) tendency.

Parental corporal punishment and adolescent drinking: the protective role of personal growth initiative and gender difference

Introduction

Parenting and peer victimization (PV) are crucial for adolescent drinking. To further explore the cause of adolescent drinking, the present study investigated the role of PV and personal growth initiative (PGI) in the relationship between parental corporal punishment (PCP) and adolescent drinking.

Methods

Present study build moderated mediation models to test the hypothesis, and detailed analysis of gender differences was conducted on the models. The data were collected in a cross-sectional questionnaire study with n = 1,007 adolescents (mean age = 13.16 years, 51.84% girls, n = 522).

Results

Model analysis showed that: (1) PV totally mediated the relationship between PCP and adolescent girls' drinking behavior; (2) The positive association between PV and drinking was only significant for girls with low PGI.

Discussion

These findings underscore the importance of the protective effect of a personality trait characterized by spontaneous self-promotion on adolescent girls' drinking.

Developmental interactions between peer victimization and depressive symptoms in adolescents: A latent change score analysis

Peer victimization and depressive symptoms are highly relevant risks during adolescence. Understanding the dynamic patterns of interactions between peer victimization and depressive symptoms as well as gender differences in these variables can improve intervention strategies for adolescents navigating this critical transition period. In the present study, a large sample of Chinese adolescents reported peer victimization and depressive symptoms in four survey waves at six-month intervals. A total of 2534 adolescents (51.9% boys, M = 12.98 ± 0.60 years) were included in the latent change score (LCS) analysis. The results supported the reciprocal effects model obtained in the full sample. Changes in peer victimization were influenced by prior changes in depressive symptoms over time, and changes in depressive symptoms were influenced by prior levels of peer victimization. There were also gender differences, with boys exhibiting depressive symptom-driven effects on peer victimization, while girls exhibiting peer victimization-induced depressive symptoms. The dynamic relationships between peer victimization and depressive symptoms that promote and constrain each other in adolescents are elucidated in this study. Differentiating effects on boys and girls is crucial for enhancing the effectiveness of practical interventions.

Peer victimization and Internet addiction among adolescents: The role of anger rumination and social dominance orientation

INTRODUCTION

Internet addiction has garnered growing attention in recent years, and peer victimization plays a major contributor to adolescents' Internet addiction. However, little is known about the mediating and moderating mechanisms in the association between peer victimization and Internet addiction. Guided by cognitive behavioral model and worldview verification model, this study examined a moderated mediation model in which anger rumination at Time 1 (T1) mediated the association between peer victimization at T1 and Internet addiction at Time 2 (T2), and this mediation effect was moderated by T1 social dominance orientation (SDO).

METHODS

A short-term longitudinal design was adopted, incorporating two measurement occasions (with approximately 6-month intervals). Participants were 2597 adolescents (51.5% male, Mage  = 13.9, SD = 0.60) from seven secondary schools in Zhengzhou City, China. All participants were invited to complete the self-reported questionnaires assessing peer victimization, anger rumination, SDO at T1 (December 2015) and Internet addiction at T2 (June 2016), respectively. A short-term longitudinal moderated mediation model was conducted to analyze the association between variables.

RESULTS

The results showed that T1 peer victimization was positively associated with T2 Internet addiction in which association was mediated by T1 anger rumination. T1 SDO moderated the associations between T1 peer victimization and T1 anger rumination and this effect was stronger with lower levels of SDO. In terms of gender differences, SDO moderated the associations between peer victimization and anger rumination only for boys.

CONCLUSIONS

Results highlight that anger rumination is a potential mechanism explaining how peer victimization is related to Internet addiction and that this relation may be moderated by SDO.

Peer victimization and children's internet addiction in China: a moderated mediation model

Background

Peer victimization used to be considered as a crucial risk factor for children addicted to the internet. Whereas some victimized ones are function better than would be expected. Variability across individuals indicates that it is necessary to understand how children cope with being bullied and why they do not exhibit maladaptive outcomes.

Objective

We explored the underlying mechanisms by testing whether subjective well-being was a mediator between peer victimization and Internet addiction and whether the mediation effects conditioned on the levels of parent-child relationship (PCR).

Methods

Data were collected from 65, 868 elementary school students in China (Mage = 9.56 years, SD = 0.62, 54.0% male) using four questionnaires.

Results

We found that: (1) subjective well-being can partially mediate the relationship of the two variables; and (2) PCR can moderate direct path and second half of the intermediary process. These moderating effects were stronger for children with higher PCR vs. lower PCR, as a strong PCR can help children to deal with intense emotions and to access effective resources to obtain support.

Conclusion

This study deepens our understanding of how peer victimization leads to internet addiction, identifies a supportive PCR as a crucial factor that strengthens the resilience of child victims, and highlights the value of focusing on improving the relationship between parents and children in intervening internet addiction related to peer victimization.

Peer functioning difficulties may exacerbate symptoms of attention-deficit/hyperactivity disorder and irritability over time: a temporal network analysis

BACKGROUND

Children with attention-deficit/hyperactivity disorder (ADHD) have been consistently found to experience impairments in peer functioning. Irritability is highly prevalent in children with ADHD and may worsen social impairments given the frequent temper outbursts and low frustration tolerance characterizing irritability. However, it is still unclear how ADHD and irritability symptoms interact with peer functioning difficulties over time. Assessing these temporal dynamics using a novel longitudinal approach (i.e., temporal network analysis) may reveal precise targets for intervention.

METHODS

This study investigates the dynamic associations between ADHD symptoms, irritability, and peer functioning in a community sample of 739 children (ages 8-11 years, Mage  = 10.06 [SD = 0.59], 47.77% females) assessed at three timepoints, 6 months apart, in a school-based study. Parents reported their child's ADHD symptoms using the Swanson, Nolan, and Pelham Rating Scale (SNAP-IV), and irritability symptoms using the Child Behavior Checklist (CBCL) irritability items. Children's peer functioning (i.e., peer acceptance, peer rejection, number of friendships, and victimization) was measured via peer nomination. To estimate the longitudinal associations between the variables, we built a graphical vector autoregression model for panel data.

RESULTS

The longitudinal network highlighted that poor peer functioning contributed to increases in symptoms over time. Specifically, (1) physical victimization predicted increases in inattention, hyperactivity, and irritability; (2) peer rejection predicted increases in inattention, which in turn predicted increases in irritability; (3) peer acceptance predicted decreases in inattention and irritability; and (4) higher numbers of mutual friendships increased inattention.

CONCLUSIONS

These results suggest that a negative social environment involving physical bullying and rejection may aggravate ADHD and irritability symptoms. Conversely, positive social interactions, such as being liked by peers, may improve inattention and irritability symptoms. Fostering social-emotional skills and positive social interactions and environments in children with ADHD and irritability may be a promising target for future interventions to reduce symptoms.

Mother-Adolescent Agreement Concerning Peer Victimization:Predictors and Relation to Coping

The current study analyzed adolescent, maternal, and family factors associated with mother-adolescent agreement on reports of verbal, relational, and physical forms of peer victimization. It also assessed the relationship between mother-adolescent agreement and adolescents' coping response to peer victimization. The sample consisted of 783 adolescents (337 male, 446 female) between the ages 13-15 and their mothers. Consistent with previous research, results showed mother-adolescent agreement to be low, with kappa coefficients ranging from .15 to .30 on items measuring adolescent peer victimization. A multinomial logistic regression analysis indicated that adolescent factors (age, gender, depression symptomology), maternal factors (depression symptomology, history of victimization), and family cohesion were significantly related to mother-adolescent agreement on reports of peer victimization. Lastly, mother-adolescent agreement on reports of adolescent peer victimization was associated with adolescents' increased use of adult support seeking and problem-solving and decreased use of passive-coping, distancing, and revenge-seeking as a coping response to peer victimization.

Chronic, increasing, and decreasing peer victimization trajectories and the development of externalizing and internalizing problems in middle childhood

Children's peer victimization trajectories and their longitudinal associations with externalizing and internalizing problems were investigated from Grades 2 to 5. Secondary data analysis was performed with the Early Childhood Longitudinal Study (ECLS-K-2011; n = 13,860, M age = 8.1 years old in the spring of Grade 2; 51.1% male, 46.7% White, 13.2% African-American, 25.3% Hispanic or Latino, 8.5% Asian, and 6.1% other or biracial). Children who experienced high and persistent levels of peer victimization (high-chronic victims) exhibited co-occurring externalizing and internalizing problems. Moreover, among high-chronic victims, boys had a more pronounced increase in their externalizing trajectories, and girls had greater increases in their social anxiety trajectories. In contrast, those with decreasing peer victimization across time exhibited signs of recovery, particularly with respect to their social anxiety. These findings elucidated how chronic, increasing, and decreasing victims exhibited distinct patterns in the co-occurring development of their externalizing and internalizing problems, and how findings varied depending on the form of problem behavior and by child sex.

Bidirectional spillover between maladaptive parenting and peer victimization and the mediating roles of internalizing and externalizing problems: A within-person analysis among Chinese early adolescents

Parenting practices and relationships with peers are crucial aspects of youth socialization. Although theoretically expected reciprocal associations between changes in maladaptive parenting and adolescent peer victimization exist, there is a lack of studies that examine this link and address the mediating mechanisms at the within-person level. This longitudinal study examined reciprocal relations between peer victimization and two types of maladaptive parenting including harsh punishment and psychological control, and the potential mediating roles of internalizing and externalizing problems within these relations, by disentangling between- and within-person effects. A total of 4,731 Chinese early adolescents (44.9% girls; M age = 10.91 years, SD = 0.72) participated in a four-wave longitudinal study with 6-month intervals. The results of random intercept cross-lagged panel modeling showed: (a) harsh punishment did not directly predict peer victimization, and vice versa; (b) psychological control directly predicted peer victimization, and vice versa; (c) psychological control indirectly predicted peer victimization via internalizing problems, and peer victimization also indirectly predicted psychological control via internalizing problems. These findings provide evidence of a bidirectional spillover effect between psychological control and peer victimization at the within-person level, suggesting Chinese early adolescents may become caught in a vicious cycle directly or indirectly via their internalizing problems.

Anxious-Withdrawal and Sleep Problems during Adolescence: The Moderating Role of Peer Difficulties

Anxious-withdrawal is a well-established individual risk factor for psychosocial difficulties during adolescence. It is unknown, however, whether it also places youth at increased risk for physical health problems, such as sleep difficulties. This study examines the concurrent and prospective associations between anxious-withdrawal and six types of sleep difficulties (i.e., sleeping too much, sleeping too little, talking/walking in sleep, being overtired, nightmares, and general trouble sleeping). We further evaluate whether these associations differ for adolescents who are high versus low in exclusion and victimization. The participants were 395 adolescents (Mage = 13.61 years; 35% ethnic minority) who completed peer nominations of anxious-withdrawal, exclusion, and victimization at Time 1 (T1). Their mothers completed reports of sleep difficulties at T1 and at Time 2 (T2). Path analyses revealed unique associations between anxious-withdrawal and several types of sleep difficulties (e.g., sleeping too much) at T1. Analyses also revealed a significant interaction effect between T1 anxious-withdrawal and exclusion/victimization such that anxious-withdrawal was prospectively associated with trouble sleeping only for those young adolescents who are highly excluded/victimized. Our findings are the first to link anxious-withdrawal to a physical health outcome in adolescence and point to the need for future research to not only examine anxious-withdrawal and physical health but also to include assessments of peer difficulties.

Reciprocal associations between peer victimization and depressive symptoms among Chinese children and adolescents: Between- and within-person effects

Peer victimization is detrimental to child mental health. Research has indicated a reciprocal relationship between peer victimization and mental health problems. Yet limited evidence was from children and adolescents in China. The present study used the random intercepts cross-lagged panel model (RI-CLPM) to examine both between-person and within-person associations between peer victimization and depressive symptoms among Chinese children and adolescents. Participants were 1205 Chinese students (Mage  = 11.27 years; ranged from 9 to 15 years; SD = 1.75; 55% boys) who completed four surveys (Time 1 to Time 4) between 2017 and 2019 on demographics, peer victimization, and depressive symptoms. At the between-person level, peer victimization was positively associated with depressive symptoms. Controlling for between-person effects, RI-CLPM suggested positive within-person effects from peer victimization to depressive symptoms across adjacent waves. The model also suggested a positive within-person effect from Time 2 depressive symptoms to Time 3 peer victimization. The multi-group analysis showed that these effects did not differ by gender, age, or subjective socioeconomic status. Peer victimization and depression appear to be reciprocally related at the transitioning period between late childhood and early adolescence in Chinese students. Mental health interventions should attend to peer victimization for children and adolescents in China.

The relationship between parent-child relationship and peer victimization: a multiple mediation model through peer relationship and depression

Introduction

Peer victimization is a highly prevalent worldwide issue with cross-cultural characteristics. Parent-child relationship and peer victimization is known to be interrelated, but how they influence each other remains unclear. This study explored the mechanisms of peer victimization related to parent-child relationship.

Methods

A total of 58,756 fourth grade students aged 10-12 years (10.83 ± 0.83, 54.4% males) from China completed four questionnaires. A multiple mediator model was tested, in which the two variables influenced each other through the mediating factors of peer relationship and depression.

Results

Peer victimization was indirectly negatively impacted by parent-child relationship through two chain mediating factors of peer relationship and depression: (1) the mediational path through peer relationship with an effect size of 44.66%; (2) the mediational path through depression with an effect size of 21.64%; and (3) the mediational path through peer relationship and depression with an effect size of 18.08%. The total mediational effect size was 84.11%.

Conclusion

The effect size through peer relationship is the strongest among the three mediation paths, suggesting that peer relationship is the key determinant in breaking the link between parent-child relationship and victimization. Poor parent-child and peer relationships may be risk factors eliciting peer victimization. Compared to internalizing behaviors (e.g., depression), low-quality interpersonal relationships maybe the root cause of the formation and maintenance of victimization. Thus, intervention programs against bullying should pay more attention on children's contextual factors, especially their relationships with their families and peers, among children at an early age.

Resilience mediates the effect of peer victimization on quality of life in Chongqing adolescents: from a perspective of positive childhood experiences

Background

Peer victimization is a harmful experience that contributed to one's psychological problems, physical health deterioration, and so on. Quality of life (QoL) is an important indicator of adolescent health assessment. To identify potential pathways of positive experiences in preventing peer victimization's detrimental effects and then provide intervention ideas for adolescent health, this study was conducted to examine the relationship between peer victimization and QoL in Chongqing adolescents and discover whether resilience plays a mediating role and positive childhood experiences (PCEs) act as a moderating role in the relationship.

Methods

Data were the first follow-up of a cohort study conducted in four complete middle schools in two districts of Chongqing, China. Self-designed peer victimization items, the Connor-Davidson Resilience Scale, the Adolescent Quality of Life Scale, and the Benevolent Childhood Experiences Scale were used. We investigated the differences and correlations in peer victimization, QoL, and resilience between the two PCEs groups. Mplus version 8.3 was used to analyze the mediating role of resilience and the moderating role of PCEs in peer victimization and QoL.

Results

Peer victimization, resilience, and QoL differed between the two PCEs groups (P < 0.001). Peer victimization negatively correlated with QoL and resilience, while resilience positively correlated with QoL (P < 0.001). In the models with total QOL as the dependent variable, the indirect effect was -0.431 (8.08% of the total effect) in the low-PCEs group vs. -2.077 (41.97% of the total effect) in the high-PCEs group. In the models with four dimensions of QOL as the dependent variable, the indirect effects ranged from -0.054 to -0.180 (6.07-12.95% of the total effects) in the low-PCEs group and from 0.295 to -0.823 in the high-PCEs group (35.89-68.76% of the total effects). Both total and indirect effects were significant (P < 0.05). In addition, the differences in indirect effects were significant between the two PCEs groups (P < 0.05), while differences in total and direct effects were almost not apparent.

Conclusion

Resilience partially mediated the effect of peer victimization on QoL in Chongqing adolescents, and PCEs moderated this mediation. Schools, families, and society should focus on resilience intervention and prioritize the enhancement of PCEs for improving adolescent QoL.

Relationship between Harsh Parenting and Aggressive Behaviors in Male Juvenile Delinquents: Potential Mediating Roles of Peer Victimization and Hostile Attribution Bias

Harsh parenting can be regarded as a harsh behaviors, feelings, and attitudes toward children in the process of parenting. According to the theory of intergenerational transmission of violence, harsh parenting is an important factor affecting children's aggressive behavior, but the theory does not clarify the specific action path between harsh parenting and aggressive behavior. In order to reveal the relationship between harsh parenting and the aggressive behavior of juvenile delinquents, 604 male juvenile delinquents (N = 604; M_age = 16.57 years; SD = 0.612 years) were investigated using the Harsh Parenting Questionnaire, the Buss-Perry Aggression Questionnaire, the Multidimensional Peer Victimization Scale, and the Word Sentence Association Paradigm for Hostility in Chinese. Analysis using structural equation modeling procedures showed that (a) all variables were positively associated with each other; (b) the partial indirect effect of harsh parenting on aggressive behaviors was determined through the mediators of peer victimization and hostile attribution bias independently; and (c) the partial indirect effect was determined through the mediators of peer victimization and hostile attribution bias sequentially. The results suggest that harsh parenting can explain the highly aggressive behavior of male juvenile delinquents. Moreover, harsh parenting may also predict the risk of peer victimization and hostile attribution bias, thereby predicting the development of highly aggressive behaviors.

Associations Between Peer Victimization and Problematic Internet Use Among Adolescents: Humor Makes a Difference

With the increasing development of science and technology, the Internet has become an essential part of people's daily lives providing great convenience. However, the Internet also leads to problematic Internet use (PIU) among adolescents, which has attracted increasing attention from the academic community. Peer victimization is a pervasive stressor among adolescents and has been proven to lead to a series of mental health challenges. Although the association between peer victimization and PIU has been well documented, the underlying mechanism remains unclear. This study aimed to understand how and when peer victimization increases the risk of PIU among adolescents. Building on Agnew's general strain theory, this study hypothesized that depression mediates the relationship between peer victimization and PIU and humor moderates the mediating model. To examine these hypotheses, 469 middle school students were recruited to complete a series of questionnaires on peer victimization, depression, humor, and PIU. The results showed that depression partially mediated the relationship between peer victimization and PIU. A moderated mediation analysis indicated that humor moderated the indirect pathway, consistent with the reverse stress-buffering model, the relationship between peer victimization and depression was stronger for adolescents with high humor. However, the relationship between depression and PIU was weaker in adolescents with high humor, which is in line with the stress-buffering model. These findings could be of significance in understanding the underlying mechanism of PIU associated with peer victimization and provide a new perspective for preventing PIU among adolescents, especially those experiencing peer victimization. The limitations and considerations for future research are discussed.

Peer Victimization and Subjective Well-Being Among Chinese Adolescents: Moderated Mediation by Forgiveness and Self-Esteem

Considerable developmental research has shown an association between peer victimization and subjective well-being among adolescents. However, the mediating processes and protective factors that constrain this association are less understood. To fill these gaps, we investigated whether self-esteem mediates the association between peer victimization and subjective well-being and whether forgiveness moderates the direct and indirect associations of peer victimization with adolescents' subjective well-being via self-esteem. A large sample of 2,758 adolescents (M_age = 13.53 years, SD = 1.06) from 10 middle schools in China participated in this study. Participants provided data on demographic variables, peer victimization, self-esteem, forgiveness, and subjective well-being by answering anonymous questionnaires. After controlling for demographic covariates, we found that self-esteem mediated the relationship between peer victimization and subjective well-being. Furthermore, as a protective factor, forgiveness moderated the relationship between peer victimization and self-esteem. Consistent with the protective-reactive model, when adolescents experienced more peer victimization, those with higher forgiveness levels exhibited a greater decline in self-esteem, and low self-esteem was then associated with decreased subjective well-being. These findings demonstrate the utility of examining both mediating and moderating factors in this relationship and highlight the negative impact of peer victimization on adolescent self-worth and the limited role of forgiveness as a protective factor.

Peer Victimization and Psychosocial Adjustment among Children of Parents with Physical Disabilities in China: A Comparative Study

This study investigated whether the children of parents with physical disabilities endured higher levels of peer victimization. Particularly, this study focused on the mediating effects of peer victimization in the relationships between parental disability and both the emotional symptoms and prosocial behaviors exhibited by their children. Data were obtained from a survey on health and mental health among children and adolescents from disadvantaged families. The survey was conducted by Renmin University of China from August to September 2018 using multistage probability sampling method. The sample in this study included 716 adolescents, of whom 390 had at least one parent with physical disabilities and reported more severe peer victimization. In contrast to respondents who did not have parents with physical disabilities, these adolescents experienced more emotional symptoms and engaged in fewer prosocial behaviors. Furthermore, the analysis showed that 15.16% of the total effect of parental disability on emotional symptoms was mediated by peer victimization, which had a nonsignificant mediating effect in the relationship between parental disability and prosocial behaviors. These findings can inform practitioners who aim to help children of parents with physical disabilities improve their coping strategies and social skills to manage peer relationships. Moreover, these results highlight the importance of establishing an inclusive school and community environment to reduce social stigma and peer victimization toward children from disadvantaged families.

Child Maltreatment, Peer Victimization, and Mental Health: Neurocognitive Perspectives on the Cycle of Victimization

Children who experience maltreatment are at increased risk of revictimization across the life span. In childhood, this risk often manifests as peer victimization. Understanding the nature of this risk, and its impact on mental health, is critical if we are to provide effective support for those children who are most vulnerable. A systematic scoping review was conducted using Google Scholar and PsycINFO. Studies on adults, psychiatric, and/or inpatient populations were excluded. Included studies concerned all forms of child maltreatment and peer victimization. We found 28 studies about the association between maltreatment experience and peer victimization as well as peer rejection. We review the evidence documenting the relation between these adverse childhood experiences and mental health. The evidence suggests that maltreatment and peer victimization have additive effects on mental health outcomes. A number of theoretical developmental frameworks that delineate putative mechanisms that might account for an association are considered. Building on prior research, we then discuss the role of recent neurocognitive findings in providing a multilevel framework for conceptualizing mental health vulnerability following maltreatment. In addition, we consider how altered neurocognitive functioning following maltreatment may shed light on why affected children are more likely to be victimized by their peers. Specifically, we consider the threat, reward, and autobiographical memory systems and their role in relation to stress generation, stress susceptibility, and social thinning. Such a mechanistic understanding is necessary if we are to reduce the likelihood of peer victimization in children exposed to maltreatment, and move to a preventative model of mental health care.

Contribution of Risk and Resilience Factors to Suicidality among Mental Health-Help-Seeking Adolescent Outpatients: A Cross-Sectional Study

BACKGROUND

Peer victimization is an established risk factor for youth suicidal thoughts and behavior (suicidality), yet most peer-victimized youth are not suicidal. More data are needed pertaining to factors that confer resilience to youth suicidality.

AIM

To identify resilience factors for youth suicidality in a sample of N = 104 (Mean age 13.5 years, 56% female) outpatient mental health help-seeking adolescents.

METHODS

Participants completed self-report questionnaires on their first outpatient visit, including the Ask Suicide-Screening Questions, a battery of risk (peer victimization and negative life events) and resilience (self-reliance, emotion regulation, close relationships and neighborhood) measures.

RESULTS

36.5% of participants screened positive for suicidality. Peer victimization was positively associated with suicidality (odds ratio [OR] = 3.84, 95% confidence interval [95% CI] 1.95-8.62, p < 0.001), while an overall multi-dimensional measure of resilience factors was inversely associated with suicidality (OR, 95% CI = 0.28, 0.11-0.59, p = 0.002). Nevertheless, high peer victimization was found to be associated with a greater chance of suicidality across all levels of resilience (marked by non-significant peer victimization by resilience interaction, p = 0.112).

CONCLUSIONS

This study provides evidence for the protective association of resilience factors and suicidality in a psychiatric outpatient population. The findings may suggest that interventions that enhance resilience factors may mitigate suicidality risk.

The meditating role of sleep in the longitudinal associations between peer victimization and internalizing symptoms: A cross-lagged panel analysis

Adolescence is a time of heightened vulnerability for both peer victimization (PV) and internalizing symptoms. While the positive association between them is well established, there is little understanding of the mechanisms underpinning this relationship. To address this gap, the current study aimed to investigate sleep hygiene and school night sleep duration as individual and sequential mediators of the relationship between PV and both depressive and social anxiety symptoms during pre- to mid-adolescence. The study drew upon a community sample of 528 Australian youth aged 10-12 years at baseline (M age = 11.19, SD = .55; 51.1% boys) and data were collected over five annual measurement occasions. Direct and indirect longitudinal and bidirectional associations were examined using cross-lagged panel analysis. There was no evidence of sequential mediation through both sleep hygiene and sleep duration to depression and social anxiety. Instead, the findings show that sleep hygiene mediated the prospective association between PV and both depressive and social anxiety symptoms, and between PV and sleep duration. Overall, sleep hygiene represents a modifiable transdiagnostic factor that can be targeted to break the cycle of PV, inadequate sleep, and internalizing symptoms.

Are there negative cycles of peer victimization and rejection sensitivity? Testing ri-CLPMs in two longitudinal samples of young adolescents

This study's aim was to examine whether there are negative increasing cycles of peer victimization and rejection sensitivity over time. Drawing from Social Information Processing Theory, we hypothesized that victimization leads to higher levels of rejection sensitivity, which would put adolescents at risk for higher future victimization. Data were collected in a four-wave study with 233 Dutch adolescents starting secondary education (Mage = 12.7 years), and a three-wave study with 711 Australian adolescents in the last years of primary school (Mage = 10.8 years). Random-intercept cross-lagged panel models were used to disentangle between-person from within-person effects. In each sample, a significant between-person association was found: adolescents with higher levels of victimization as compared to their peers also reported higher levels of rejection sensitivity. At the within-person level, all concurrent associations between individual fluctuations of victimization and rejection sensitivity were significant, but there were no significant cross-lagged effects (except in some sensitivity analyses). These findings demonstrate that victimization and rejection sensitivity are interrelated, but there may not be negative victimization-rejection sensitivity cycles during the early-middle adolescent years. Possibly, cycles establish earlier in life or results are due to shared underlying factors. Further research is needed examining different time lags between assessments, age groups, and contexts.

Trajectories of physical and relational aggression across early childhood: Relations with peer risk factors

The goal of the current study was to examine trajectories of relational and physical aggression in early childhood and evaluate peer predictors of these trajectories (i.e., peer rejection, relational victimization, and physical victimization). The study spanned three-time points (T1 in the spring, T2 in the fall, and T3 in the spring) in early childhood (N = 300; 44.0% girls; M_age  = 44.70 months, SD = 4.38; 3.0% African American/Black, 7.6% Asian/Asian American/Pacific Islander, 1.0% Hispanic/Latinx, 11.3% multiracial, 62.1% White, and 15.0% missing/unknown). Observations of peer victimization and teacher report of peer rejection were collected at T1, and teacher report of aggression was collected at all time points. Results from piecewise latent growth models demonstrated that both forms of aggression decreased from T1 to T2 as children entered a new classroom and increased from T2 to T3 as they remained in that classroom. The increase in physical aggression from T2 to T3 was only significant for boys. Peer rejection at T1 emerged as a predictor of both intercepts and slopes from T1 to T2, and physical victimization predicted the physical aggression intercept and physical aggression slope from T1 to T2. Children high on these peer risk variables had higher initial levels of aggression, followed by a greater decrease in aggression from T1 to T2. Results underscore the importance of studying incremental change in aggression in early childhood and suggest that children who experience negative peer treatment have greater fluctuations in aggression over time.

Gene-Environment Interplay Linking Peer Victimization With Adolescents' Trajectories of Depressive Symptoms

OBJECTIVE

This study examined to what extent genetic and environmental factors explain-either additively or interactively with peer victimization-different trajectories of adolescents' depressive symptoms and whether genetic factors related to distinct trajectories are correlated with peer victimization.

METHOD

Participants included 902 twins (52% girls) who self-reported peer victimization and depressive symptoms in grades 6, 7, 8, 9, and 11.

RESULTS

Growth mixture modeling revealed 3 trajectories of depressive symptoms: low (69.2% of participants), increasing (19.5%), and high-decreasing-increasing (11.3%). Biometric modeling showed that, for both sexes, genetic factors explained roughly half (52.6%, 47.5%) of the probability of following either a low or an increasing trajectory. Genetic influences (41%) were also observed for the high-decreasing-increasing trajectory, albeit only for girls. Nonshared environmental influences explained the remaining variances, along with shared environmental influences (27%) on the high-decreasing-increasing trajectory. Only for the low and the increasing trajectories, nonshared environmental influences increased with more frequent peer victimization (b_low = 0.206, 95% CI [0.094, 0.325]; b_increasing = 0.246, 95% CI [0.143, 0.356]). Moreover, peer victimization was associated with a lower probability of a low trajectory and a higher probability of an increasing or high-decreasing-increasing trajectory, and these associations were mostly explained by common underlying genetic factors.

CONCLUSION

Youth expressing (partly inherited) depressive symptoms may be at risk of peer victimization. However, increasing depressive symptoms in victims may be mitigated by other environmental factors except for those who enter adolescence with already high levels of depressive symptoms.

Peer Victimization and Adolescent Non-Suicidal Self-Injury: The Mediating Role of Alienation and Moderating Role of Mindfulness

Peer victimization and non-suicidal self-injury (NSSI) are two major public health problems, with the former being associated with outward attack and the latter characterizing inward attack. Peer victimization has been shown to be associated with adolescents' NSSI. However, less is known about the mechanism underlying the association. Based on the experiential avoidance model of NSSI, this study tested whether the sense of alienation mediated the association between peer victimization and NSSI, and whether this process was weakened by mindfulness. A total of 1,574 Chinese adolescents (51.1% girls; ages 12-16 years) completed questionnaires concerning NSSI, peer victimization, alienation, and mindfulness. Regression-based analyses indicated that peer victimization predicted adolescents' NSSI through the indirect effect of alienation, and mindfulness weakened this indirect effect. These findings suggest that victimized adolescents may injure themselves as an emotion regulation strategy. The results highlight the importance to implement programs aimed to improve the school climate to reduce the risk of adolescent NSSI. Furthermore, we underscore the need to include emotion-regulation training (e.g., mindful practice) into bully intervention programs to prevent NSSI.

Longitudinal associations between coping and peer victimization: Moderation by gender and initial peer victimization

Stress coping theories suggest that the effectiveness of coping depends on the level of stress experienced. Existing research shows that efforts to cope with high levels of peer victimization may not prevent subsequent peer victimization. Additionally, associations between coping and peer victimization often differ between boys and girls. The present study included 242 participants (51% girls; 34% Black, 65% White; Mage = 15.75 years). Adolescents reported on coping with peer stress at age 16 and on overt and relational peer victimization at ages 16 and 17. Greater use of primary control engaged coping (e.g., problem-solving) was associated positively with overt peer victimization for boys with higher initial overt victimization. Primary control coping was also associated positively with relational victimization regardless of gender or initial relational peer victimization. Secondary control coping (e.g., cognitive distancing) was associated negatively with overt peer victimization. Secondary control coping was also associated negatively with relational victimization for boys. Greater use of disengaged coping (e.g., avoidance) was associated positively with overt and relational peer victimization for girls with higher initial victimization. Gender differences and the context and level of stress should be considered in future research and interventions related to coping with peer stress.

Can Lower Levels of Classroom Victimization be harmful? Healthy Context Paradox Among Chinese Adolescents

The healthy context paradox is defined as the phenomenon that victims' psychological adjustment worsens in a context with a lower rate of victimization. The unexpected pattern was primarily confirmed in children and adolescents from western societies, and it is unclear whether classroom-level victimization could moderate the link between peer victimization and psychological adjustment in the Chinese cultural context, where Confucian philosophies and collectivism are highly valued. Furthermore, most existing research used a single method to assess peer victimization. The current study attempted to examine classroom-level peer victimization as a moderator in the association between individual-level peer victimization and depression, self-esteem, and well-being among 2613 Chinese seventh graders (1237 girls, M_age = 13.00±.61) from 47 classrooms (M_{classroom size} = 55.60, range from 45 to 65) using both self-reported and peer-reported information on peer victimization. At the individual level, the results revealed that both self- and peer-reported victimization were positively related to depression and negatively related to self-esteem and well-being. Most importantly, consistent with past findings documenting the healthy context paradox, self-reported victimized youth experienced a higher level of depression and lower level of self-esteem and well-being in classrooms where the overall level of victimization was relatively low. However, the healthy context paradox was not replicated in the nominated data of peer victimization. These results confirmed the healthy context paradox in Chinese culture to some extent. The findings emphasize the importance of measuring peer victimization from multiple sources and suggest there is a need for additional support to victimized middle school students where the classroom context was relatively healthy.

Early co-occurrence of peer victimization and aggression

An accelerated longitudinal research design was used to examine heterogeneity in the developmental co-occurrence of peer relational victimization and aggression and of peer overt victimization and aggression from age 4.5 to 10.5 years. Data were gathered from four cohorts of children in kindergarten to Grade 3 (N = 503) on six occasions across 2 years. Psychopathology, peer, and social-cognitive factors were examined as predictors of the joint trajectories. Sequential process latent growth mixture models identified four distinct subgroups for the relational trajectories (co-occurring increasing aggression, co-occurring increasing victimization, high chronic victimization, typical low risk) and four distinct subgroups for the overt trajectories (co-occurring decelerating aggression, high chronic victimization, moderate chronic victimization, typical low risk). Membership in the co-occurring trajectories was associated with psychopathology and membership in the chronic victimization trajectories was related to internalizing and social-cognitive problems but also peer likeability.

Is it my fault? The role of the feeling of guilt in adolescent peer victimization

Introduction

The aim of this study was to analyze the relationships between feelings of guilt, peer victimization in school, and loneliness based on adolescents' gender.

Methods

A total of 671 Spanish students (50.7% boys), aged 10-16 years old (M = 13.04, SD = 1.80) from six public primary and secondary schools participated in the study. A Multivariate Analysis of Variance (3 × 2) was calculated.

Results

Adolescents with high levels of guilt presented greater physical, verbal, and relational victimization, as well as higher levels of loneliness. In addition, boys high in guilt had the highest scores in overt physical victimization, while girls high in guilt had the highest levels of loneliness.

Discussion

Results obtained suggest that adolescents with greater feelings of guilt feel responsible for being victims of peer aggression and for feeling lonely. These findings suggest the need to address the feeling of guilt, taking into account the gender perception.

Associations between epigenetic aging and childhood peer victimization, depression, and suicidal ideation in adolescence and adulthood: A study of two population-based samples

Background: Prior studies indicate that peer victimization (including bullying) is associated with higher risk for depression and suicidal ideation across the life course. However, molecular mechanisms underlying these associations remain unclear. This two-cohort study proposes to test whether epigenetic aging and pace of aging, as well as a DNA methylation marker of responsive to glucocorticoids, are associated to childhood peer victimization and later depressive symptoms, or suicidal ideation. Methods: Cohort 1: Epigenome-wide DNA methylation (EPIC array) was measured in saliva collected when participants were 10.47 years (standard deviation = 0.35) in a subsample of the Quebec Longitudinal Study of Child Development (QLSCD, n = 149 participants), with self-reported peer victimization at 6-8 years, depressive symptoms (mean symptoms, and dichotomized top 30% symptoms) and suicidal ideation at 15-17 years. Cohort 2: Epigenome-wide DNA methylation (EPIC array) was measured in blood collected from participants aged 45.13 years (standard deviation = 0.37) in a subsample of the 1958 British Birth cohort (1958BBC, n = 238 participants) with information on mother-reported peer victimization at 7-11 years, self-reported depressive symptoms at 50 years, and suicidal ideation at 45 years. Five epigenetic indices were derived: three indicators of epigenetic aging [Horvath's pan-tissue (Horvath1), Horvath's Skin-and-Blood (Horvath2), Pediatric-Buccal-Epigenetic age (PedBE)], pace of aging (DunedinPACE), and stress response reactivity (Epistress). Results: Peer victimization was not associated with the epigenetic indices in either cohort. In the QLSCD, higher PedBE epigenetic aging and a slower pace of aging as measured by DunedinPACE predicted higher depressive symptoms scores. In contrast, neither the Horvath1, or Horvath2 epigenetic age estimates, nor the Epistress score were associated with depressive symptoms in either cohort, and none of the epigenetic indices predicted suicidal ideation. Conclusion: The findings are consistent with epigenome-wide and candidate gene studies suggesting that these epigenetic indices did not relate to peer victimization, challenging the hypothesis that cumulative epigenetic aging indices could translate vulnerability to depressive symptoms and suicidal ideation following peer victimization. Since some indices of epigenetic aging and pace of aging signaled higher risk for depressive symptoms, future studies should pursue this investigation to further evaluate the robustness and generalization of these preliminary findings.

Adolescent Peer Victimization and Deliberate Self-Harm: A Three-Wave Moderated Mediation Model

Background: Identifying deliberate self-harm (DSH) and peer victimization in adolescents is a public health issue. The present study evaluates a three-wave longitudinal model to examine the effect of peer victimization on DSH and the roles of internalizing problems (depression and anxiety) and perceived peer and teacher support climate in this relationship. Methods: The participants were 2381 adolescents (51.2% boys, Mage = 13.38, SD = .59) from Chinese middle schools. Self-report measures were used to collect data every 6 months in three waves. Results: (1) Peer victimization at T1 positively predicted DSH at T3. (2) Depression at T2, rather than anxiety, mediated the relationship between peer victimization at T1 and DSH at T3. (3) Perceived peer support climate at T1 played a moderating role between peer victimization at T1 and depression and anxiety at T2, but perceived teacher support climate did not. Peer victimization had a stronger predictive effect on depression and anxiety for students with high level of perceived peer support climate. Limitations: Study limitations include the short interval (6 months) of the longitudinal design, the reliance on self-report questionnaires, the inclusion of only one aspect of student-student and teacher-student relationships, and the age limitation. Conclusions: The results demonstrated the importance of prevention for improving social and emotional skills to reduce peer victimization and of interventions to promote a peer support climate in the classroom. The findings highlight the need to consider different types of internalizing problems and perceived support in studies of DSH in adolescents.

A longitudinal mediation study of peer victimization and resting-state functional connectivity as predictors of development of adolescent psychopathology

Background

Peer victimization (PV) is associated with alterations in neural responses in regions subserving emotional regulatory processes and with increased risk of psychopathology during adolescence. The present study examined the longitudinal mediating effects of resting-state functional connectivity (rsFC) between adolescent PV and subsequent internalizing (depression and anxiety), and externalizing (conduct and hyperactivity/inattention) symptoms.

Methods

151 adolescents (baseline mean age 12-14; 54% males) were assessed and imaged three times during a five-year period. We focused on rsFC of a priori determined Regions-of-Interest (ROIs) guided by the literature (i.e., amygdala, anterior and posterior insula, anterior cingulate cortex, and medial prefrontal cortex). Multilevel mediation (MLM) analyses simultaneously examined the between-person, concurrent within-person, and lagged within-person associations between PV and internalizing/externalizing symptoms through changes in couplings of the amygdala with the other four ROIs. All models controlled for the effects of self-reported childhood maltreatment and sex differences.

Results

An increased rsFC of the amygdala-posterior insula significantly mediated the lagged within-person association of PV and internalizing symptoms (β = 0.144; 95% CI [0.018, 0.332]). This effect was significant regardless of childhood maltreatment, concurrent externalizing symptoms, and sex differences. The rsFC did not mediate the relationship between PV and externalizing symptoms.

Conclusions

Results of this study suggest that adolescent PV may lead to long-lasting maladaptive neural communication between emotional response and sensory perception of pain (i.e., bottom-up emotion regulation) and that these neural responses may serve as unique markers for increased internalizing symptoms that appear in later adolescence in peer-victimized youth. These findings have implications for interventions targeting internalizing symptoms in victimized adolescents.

Attentional bias for sad facial expressions in adults with a history of peer victimization

Introduction

Previous research has indicated altered attentional processing in individuals with experiences of maltreatment or victimization in childhood and adolescence. The present study examined the impact of child and adolescent experiences of relational peer victimization on attentional processes in adulthood when confronted with emotional facial expressions.

Methods

As part of an online study, a community sample of adults completed a facial dot-probe task. In the present task, pictures of facial expressions displaying four different emotions (anger, disgust, happiness, and sadness) were used.

Results

The results of the hierarchical regression analyses showed that retrospective reports of peer victimization made a significant contribution to the prediction of facilitated orienting processes for sad facial expressions. Experiences of emotional child maltreatment, on the other hand, made a significant contribution to the prediction of attentional biases for angry facial expressions.

Discussion

Our results emphasize the relevance of experiences of emotional and relational maltreatment in childhood and in adolescence for the processing of social stimuli in adulthood. The findings regarding emotional child maltreatment are more indicative of attentional biases in the context of threat detection, whereas the altered attentional processes in peer victimization are more indicative of mood-congruent biases. These altered processes may be active in social situations and may therefore influence future social situations, behavior, feelings, and thus mental health.

Motivational mediation between coping and post-traumatic growth in previously bullied college students

Research has consistently shown that experiences of peer victimization may have long lasting negative consequences on health and academic achievement. Less attention has been paid to the association between past bullying and post-traumatic growth in college students. This cross-sectional study aims to examine the role of different motivational orientations (The Behavioral Inhibition and Behavioral Activation Systems (BIS/BAS) and regulatory focus) as potential mediators between cognitive strategies (rumination and resilient coping) and post-traumatic growth (PTG). Using a large sample of 1,134 college students, 85 were selected who were in their first year of college and had reported having previously experienced bullying. After classifying the participants acording to their the 33^rd and 66^th percentile scores on post-traumatic growth, a univariate analysis of variance (ANOVA) indicated significant differences between the low and high groups, with those highest in PTG showing the highest scores on drive approach, focus on promotion, and resilient coping. Conditional process analysis with these significant variables revealed that regulatory focus on promotion mediates between resilient coping and post-traumatic growth, whereas drive moderates the link between both variables. The findings shed light on the motivational mechanisms underlying PTG, which may be useful to guide interventions to prevent the consequences of bullying.

Experiences of peer victimization and teacher support in secondary school predict university enrolment 5 years later: Role of school engagement

BACKGROUND

Peer victimization has an adverse effect on academic outcomes. However, longitudinal research on how peer victimization affects access to higher education is lacking.

AIMS

In this study, we investigated the mechanisms through which peer victimization and teacher support affect aspirations for and enrolment at university 5 years later through engagement in secondary school. We also examined whether these effects were moderated by ethnicity, and whether teacher support may compensate for the effects of peer victimization.

SAMPLE

The sample (N = 15,110, 51% male, 68% White, 12% Black and 20% Asian) was drawn from a nationally representative study of young people in England. We used data from four waves, following adolescents over 3 years of secondary education (T1-T2-T3, age 13 to 15 years) until university (T4, age 18 years).

METHOD

Data were analysed in a longitudinal structural equation model in Mplus 8.

RESULTS

Adolescents subjected to more peer victimization at T1 had lower university aspirations 2 years later and were less likely to attend university 5 years later. These effects were mediated via secondary school engagement. Teacher support at T1 was related to higher school engagement, leading to higher aspirations (T3) and higher likelihood of university enrolment (T4) over time. We also found evidence that teacher support may lessen the effect of peer victimization on school engagement, and that ethnic background may moderate the effect of teacher support.

CONCLUSIONS

Peer victimization had a small long-lasting negative effect on university choices via school engagement, while teacher support had a positive effect. In summary, relationships in secondary school have long-lasting implications for university aspirations and enrolment.

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 (p_FWE  <.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.

The Association between Peer Victimization and Risk-Taking Behavior among Chinese Adolescents: Testing a Moderated Mediation Model

Peer victimization has been considered a main source of risk-taking behavior among adolescents, but little is known about the mechanisms underlying this association. Based on the social-cognitive theory and the person-environment interactions model, the current study built a moderated mediation model to explore whether self-control mediated the link between peer victimization and adolescent risk-taking behavior and whether positive parenting moderated this link. We used a 2-time longitudinal design (6 months apart) to investigate 488 adolescents (M_age = 15.63 years, SD = 1.64) from 3 middle schools in Guangzhou. The results were as follows: (1) There were significant correlations among peer victimization, adolescent risk-taking behavior, self-control, and positive parenting when controlling for demographic variables. (2) Peer victimization not only influenced risk-taking behavior directly, but also indirectly through self-control. (3) Positive parenting moderated the influence of self-control on risk-taking behavior. In other words, positive parenting could enhance the inhibitory effect of self-control on risk-taking behavior. The results help reveal the mechanism by which adolescent risk-taking behavior forms and may help inform interventions against adolescent risk-taking behavior.

Peer sexual harassment, affect, and substance use: Daily level associations among adolescents

INTRODUCTION

Peer sexual harassment is associated with adolescent substance use at the global level; however, it is unknown whether substance use occurs proximal in time to the sexual harassment experience. This study used daily reports to examine the proximal relations between sexual harassment victimization and affect and substance use. Based on theories of self-medication, we hypothesized that negative affect and substance use (cigarettes, electronic cigarettes, alcohol, and marijuana) would be higher than typical on days when sexual harassment occurred relative to nonvictimization days.

METHOD

A community sample of 13-16-year-old adolescents (N = 204, 55.4% female) from a metropolitan area in the northeastern United States completed 56 days of online reports assessing experiences with peer sexual harassment, substance use (cigarettes, electronic cigarettes, alcohol, and marijuana), and positive and negative affect.

RESULTS

Multilevel modeling revealed that experiencing sexual harassment on a given day was associated with higher than typical negative affect on that day, relative to nonvictimization days. The likelihood of cigarette and alcohol use (but not electronic cigarettes, marijuana, or positive affect) was greater on days when sexual harassment occurred.

CONCLUSION

Sexual harassment victimization is proximally associated with negative affect and alcohol and cigarette use, suggesting that adolescents may be using substances to cope with sexual harassment victimization. The co-occurrence of sexual harassment with negative affect and substance use points to the need for prevention efforts that conjointly address sexual harassment victimization, coping, and substance use.
