How Peer Victimization in Childhood Affects Social Networking Addiction in Adulthood: An Examination of the Mediating Roles of Social Anxiety and Perceived Loneliness

ABSTRACT Research to date has rarely addressed the association between peer victimization in childhood and social networking addiction in adulthood, much less the internal mechanism underlying that association. By integrating the relational self-system processes model and the cognitive–behavioral model of pathological internet use, our study marked an initial effort to explore whether social anxiety and perceived loneliness independently and/or sequentially mediate the impact of peer victimization on social networking addiction. Using school-based random cluster sampling, we recruited 1,136 students at various colleges in eastern, central, and western China (mean age = 21.98 years, 56.2% women) to complete an online survey. The results confirmed social anxiety’s single mediation effect, perceived loneliness’s single mediation effect, and the serial mediation effect of social anxiety and perceived loneliness between peer victimization and social networking addiction. The findings suggest that certain psychopathological and cognitive factors mediate the effect of peer victimization in childhood on individuals’ symptoms of social networking addiction in adulthood both independently and sequentially. Our research contributes to clarifying how interpersonal stressors lead to psychopathological symptoms, maladaptive cognitions, and, in turn, addictive behavior, which has important implications for theory, interventions, and future research.

Effects of Peer Victimization in Childhood and Trait Anxiety on Job Stress in Adulthood.

The experience of peer victimization in childhood increases the risk of developing anxiety disorders and depression, risk of suicide, as well as sensitivity to stress, in adulthood. Various personality traits are known to be associated with these effects. However, the influence of trait anxiety on job stress has not yet been reported. In the present study, we tested the hypothesis that the experience of peer victimization in childhood and trait anxiety influence job stress in adulthood. A questionnaire survey, including State-Trait Anxiety Inventory, Childhood Victimization Rating Scale, and Brief Job Stress Questionnaire, was administered to 566 adult workers. The interrelationship between multiple variables was analyzed by multiple regression analysis and path analysis. In the path model, childhood peer victimization had a positive direct effect on trait anxiety and the psychological and physical stress response (PPSR). Trait anxiety had a positive direct effect on job stressors and PPSR, and job stressors had a positive direct effect on PPSR. Regarding indirect effects, childhood peer victimization had a significant adverse effect on job stressors and PPSR via trait anxiety. Our results showed that childhood peer victimization has a negative impact on job stress in adulthood, which is influenced by trait anxiety. Interventions to address peer victimization in childhood and trait anxiety may reduce job stress in adulthood, and thus contribute to improved occupational mental health and productivity in the workplace.

Teacher–student relationships and peer victimization among Chinese children: The roles of peer status and gender

AbstractPrevious studies have shown that peer victimization causes a great variety of severe adverse effects on children's development, and it is necessary to explore the influential factors and mechanisms of peer victimization. This study examined the associations between teacher–student relationships and peer victimization, as well as the roles of peer status and gender in China. The participants were 734 primary school students from Grades 5 ~ 6. Structural equation models were conducted to test the roles of peer status in the associations between teacher–student relationships and peer victimization, as well as the gender differences in the above associations. The findings showed that teacher–student closeness negatively predicted peer victimization, and teacher–student conflict positively predicted peer victimization. It was also found that teacher–student conflict but not closeness could negatively predict peer status, which was in turn negatively associated with peer victimization. The above associations did not vary across genders. The findings indicated that both teacher–student closeness and conflict were directly associated with children's peer victimization, and teacher–student conflict was indirectly associated with peer victimization via peer status. This implies that interventions for decreasing children's peer victimization should not only focus on improving teacher–student relationships but also target peer status.

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 10.47years (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 6-8years, depressive symptoms (mean symptoms, and dichotomized top 30% symptoms) and suicidal ideation at 15-17years. Cohort 2: Epigenome-wide DNA methylation (EPIC array) was measured in blood collected from participants aged 45.13years (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 7-11years, self-reported depressive symptoms at 50years, and suicidal ideation at 45years. 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.

Within-person reciprocal associations between peer victimization and need for approval.

Prior research links need for approval (NFA; the extent to which self-worth is contingent on peer approval or disapproval) to critical developmental outcomes, but little is known about how NFA develops over time or within social contexts. To address this gap, the present study used a sophisticated analytic approach (autoregressive latent trajectory modeling with standardized residuals) to examine dynamic associations between one salient social experience-peer victimization-and two dimensions of NFA, conceptualized in terms of approach motivation (NFAapproach; enhanced self-worth based on peer approval) and avoidance motivation (NFAavoid; depleted self-worth based on peer disapproval). Following 636 youth (338 girls; Mage = 7.96 years at Wave 1; 66.7% White; 35.0% subsidized school lunch) from second to seventh grade, analyses revealed that peer victimization predicts subsequent increases in NFAavoid, which in turn predicts subsequent increases in victimization. Findings also revealed that although mean levels of NFAavoid decrease during childhood, increases or decreases in NFA become more entrenched. Thus, childhood peer victimization may disrupt normative decreases in NFAavoid and contribute to a cycle in which negative peer judgments increasingly foster low self-worth and further peer difficulties. Preventing this cycle may require encouraging peer-victimized youth to base their self-worth on internal standards rather than peer feedback while helping them develop positive relationships that promote self-worth.

Profiles of family maltreatment and peer victimization: Associations with psychosocial adjustment in Chinese children

BackgroundAlthough the family and peer systems are both important for children's development, few studies have simultaneously considered the impact of adversity experienced in these systems on children. ObjectiveThe first purpose of this study was using latent profile analysis (LPA) to identify profiles of family maltreatment (i.e., physical abuse, emotional abuse, and neglect) and peer victimization (i.e., physical victimization and relational victimization) among Chinese elementary school children. The second purpose was to examine associations between the identified profiles and short-term psychosocial adjustment (i.e., self-esteem, depression symptoms, prosocial behavior, and externalizing behavior). Participants and settingThe sample included 4313 children (45.6 % girls) with an average age of 10.9 years (SD = 0.49) from a large city in China. MethodAssessments were conducted on two occasions six months apart. Family maltreatment and peer victimization were assessed at Time 1. Psychosocial adjustment was assessed at Time 2. ResultsThe potential complexity of children's adversity experiences was revealed in that six profiles of family maltreatment and peer victimization in children were identified: (a) Low-risk; (b) Slight peer victimization; (c) Severe peer victimization; (d) Serious neglect; (e) Severe maltreatment; (f) Doubly disadvantaged. Children in the low-risk profile showed the best psychosocial adjustment whereas children in the doubly disadvantaged profile showed the worst psychosocial adjustment. The findings revealed additional differences in the subsequent psychosocial adjustment of the children in the six profiles. ConclusionsThe identification of multiple profiles and differing relations to psychosocial adjustment implies that interventions should be tailored to members of specific profiles.

Psychiatric Disorders and Peer-Victimization in Children and Adolescents With Growth Hormone Deficiency.

In this study, we aimed to investigate psychiatric disorders, bullying/victimization, and quality of life in children and adolescents with idiopathic growth hormone deficiency (GHD). Sixty-one children and adolescents who were diagnosed as having idiopathic GHD were evaluated using a semistructured interview by a child and adolescent psychiatrist. Some 45.9% of the subjects with GHD were diagnosed with at least 1 psychiatric disorder. The most common psychiatric diagnosis was social anxiety disorder (18.3%). Twenty-eight percent of the subjects reported being bullied by their peers. Victimization rates were less frequent in those treated for more than 1 year. Children aged between 6 and 12 years had poorer quality of life and higher anxiety levels than adolescents aged between 13 and 18 years. Due to the higher rates of existing psychiatric disorders, the clinical management of patients with GHD should be conducted with a multidisciplinary approach, in which pediatric endocrinologists and mental health professionals work in coordination.

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.

Peer relations and friendships in early childhood: The association with peer victimization.

We examined the association between involvement in peer victimization in early childhood and different measures of peer relations to examine the role of the peer group in victimization with a special focus on the role of the aggressor, defender, and target. Children (N = 200; 45.5% girls) and teachers (N = 8; 100% women) were recruited from three primary schools in the south‐east of England. Children were aged 5−7 years (M = 75.6 months, SD = 10.39). Child and teacher reports of children's friendships were obtained. Children reported on the quality of their best friendship. Children provided peer reports on involvement in peer victimization (as aggressor, defender, and target) and social status (like‐most and like‐least). Results show that aggressive children received more like‐least nominations than other children, defenders were the most liked by peers, but targets' social status was not clearly identifiable. There were no significant differences between role in peer victimization and best friend nominations—most children said that they had a best friend. Similarly, there were no differences in reciprocated friendship between different roles. However, children who had their friendship reciprocated received more defender nominations. In line with the homophily hypothesis, aggressive children tended to have aggressive friends and have friendships characterized by conflict. Defenders were friends with other defenders. Targets tended to follow the social competence model of friendships by indicating defenders as their best friends. We discuss these findings in relation to the role that group processes may play in peer victimization in early childhood.

Peer Victimization Influences Attention Processing Beyond the Effects of Childhood Maltreatment by Caregivers.

BackgroundDifferent types of maltreatment (emotional, physical, and sexual) lead to distortions in emotion and attention processing. The present study investigated whether the experience of peer victimization in childhood and adolescence has an additional influence on attention processing in adulthood.MethodsTwo non-clinical samples consisting of individuals with different levels of experiences of maltreatment were recruited. In an evaluative conditioning task, images of faces with neutral emotional expression were either associated with short videos of intense negative statements, or associated with neutral videos. Subsequently, these faces were used as stimuli in an emotional Stroop task as well as a dot-probe task.ResultsIn both tasks, hierarchical regression analyses revealed that retrospective reports of relational peer victimization made an incremental contribution to the prediction of attentional biases beyond child maltreatment. In the emotional Stroop task, emotional abuse was the strongest predictor for an attentional bias showing delayed responses to negatively associated faces, while peer victimization was associated with faster responses to negatively associated faces. In the dot-probe task, relational peer victimization was the strongest predictor for an attentional bias. When the attentional bias was examined in more detail, though, peer victimization did not show incremental contributions although emotional abuse remained the strongest predictor for facilitated attention toward negatively associated neutral faces.ConclusionExperiences of peer victimization leave additional cognitive scars beyond effects of childhood maltreatment by caregivers. It is likely that attentional biases in the aftermath of victimization put individuals at risk for the development of psychopathology.

A multi-informant and multi-polygenic approach to understanding predictors of peer victimisation in childhood and adolescence.

Peer victimisation is a prevalent occurrence in childhood and adolescence and can often have long-lasting consequences. Previous research using polygenic scores (PGSs) have revealed various genetic vulnerabilities as predictive of victimisation in childhood. However, findings were based on self-report and may therefore be influenced by varying self-perceptions. Previous investigations also focused on average victimisation across childhood, and thus do not capture variability in polygenic predictability over time. The present study, therefore, aimed to investigate associations between PGSs and victimisation using separate and combined reports from teachers and peers in childhood, as well as self-reports in later adolescence to explore trajectories of victimisation. Data were derived from the Quebec Newborn Twin Study. Participants were assessed for victimisation using self-reports from 7 to 17years and using teacher ratings and peer nominations between 7 and 10years (n=536). Ten PGSs related to mental health, cognitive abilities and physical traits were examined as possible predictors of victimisation using linear regressions and growth curve models. Findings revealed that PGSs associated with victimisation are consistent across informants, but to varying extent according to estimated effect sizes. Self-reported victimisation was predicted by PGSs related to mental health, while PGSs related to cognitive and physical traits had larger effect estimates when predicting teacher- and peer-reported victimisation. The PGS for educational attainment was consistently negatively associated with victimisation across informants, producing the largest effect estimates (β=-.104, 95% CI=-.169 to -.039) when predicting a multi-informant measure of victimisation. No PGS predicted changes in victimisation over time. While the PGS for educational attainment is a robust predictor of victimisation, many PGSs are differentially associated with victimisation depending on the informant. Such findings highlight the need to pay close attention to the phenotypic assessment of victimisation, and show that using multiple informants can both strengthen and provide unique insight into how associations may occur.

Pathways From Witnessing Parental Intimate Partner Violence to Involvement in Bullying: Empirically Testing a Proposed Conceptual Framework

We tested a proposed conceptual framework in which we hypothesized that witnessing parental intimate partner violence (witnessing parentalIPV) is linked to children's bullying and peer victimization. We also hypothesized that the relationship between witnessing parental IPV and bullying and peer victimization in childhood would be mediated by increased psychological problem behavior, school absences, and problematic peer interactions. We utilized data from the National Survey of Children's Health. We found that witnessing parental IPV was positively related to children's bullying and peer victimization not only directly, but also indirectly through the mediating role of psychological problem behavior, school absences, and problematic peer interactions. Our findings highlight the importance of exploring the mechanisms by which bullying and peer victimization increase in those who have witnessed parental IPV.

Contributions of childhood peer victimization and/or maltreatment to young adult anxiety, depression, and suicidality: a cross-sectional study

BackgroundChildhood maltreatment and peer victimization are major risk factors for depression and suicidal behavior. Furthermore, childhood maltreatment increases the risk of peer victimization. Our objective was to distinguish between the contributions of parental maltreatment and peer victimization to the development of mental health problems in young adulthood. Specifically, we tested whether peer victimization alone or in combination with parental maltreatment before 18 years old was associated with anxiety, depression, and suicidal thoughts and behaviors at age 21 years.MethodsWe analyzed data collected from questionnaires administered in the i-Share (Internet-based Students’ Health ResearchEnterprise) study in France from February 2013 to September 2019 (N = 2271 participants). We performed multinomial and binary logistic regression analyses to assess the single and combined contributions of childhood peer victimization and parental maltreatment to anxiety, depression, and suicidality in adulthood.ResultsNearly one third of students (28.8%) reported at least one mental health problem; 29.8% reported peer victimization alone; 7.5% reported parental maltreatment alone; and 10.3% reported both parental maltreatment and victimization. In multivariate models, compared to participants that did not experience maltreatment or peer victimization, those that experienced peer victimization alone were more likely to report anxiety (adjusted odds ratio [aOR]: 1.90; 95% CI: 1.50–2.40), depression (aOR: 1.95; 95% CI: 1.46–2.60), or suicidal ideation, without (aOR: 1.62; 95% CI: 1.26–2.09) or with a suicide attempt (aOR: 2.70; 95% CI: 1.51–4.85). Similar associations were observed for participants that experienced maltreatment alone. Participants that experienced both maltreatment and peer victimization were at increased risk of depression (aOR: 2.63; 95% CI: 1.79–3.86) and suicidal ideation, with (aOR: 9.19; 95% CI: 4.98–16.92) and without a suicide attempt (aOR: 2.64; 95% CI: 1.86–3.76).ConclusionsSeparate and combined exposures to parental maltreatment and peer victimization in childhood or adolescence were associated with increased risks of anxiety, depression, and suicidal behaviors. Peer victimization appeared to play a specific role in mental health disorders that were not otherwise explained by polyvictimization. Currently, peer victimization is a frequent, but avoidable type of child abuse; therefore, these findings have implications for policies for preventing and dealing with peer victimization.

Childhood Peer Victimization, Identity Diffusion and Disordered Eating Behaviors in Emerging Adults

Childhood peer victimization (CPV) has been associated with clinical and subclinical forms of disordered eating behaviors (DEBs). However, less is known about the mechanisms involved in this association, especially in emerging adulthood. The present study examined the relationship between harmfulness of the CPV experiences, identity diffusion and DEBs using Structural Equation Modeling. Emphasis was given in the investigation of the indirect effect of CPV harmfulness on DEBs through identity diffusion. Data from 414 emerging adults was collected via an online questionnaire. The analysis indicated significant direct effects of CPV harmfulness on both restrictive and binge-eating. More importantly, findings supported the indirect relationship between CPV harmfulness and binge-eating through identity diffusion. Results provide preliminary support for the role of CPV harmfulness and identity diffusion as contributing factors in the development of DEBs in emerging adults. Implications for future research are discussed.

Parental Corporal Punishment and Peer Victimization in Middle Childhood: A Sex-Moderated Mediation Model of Aggression.

There is a peak in peer victimization during middle childhood, with multiple negative consequences. Parental use of corporal punishment and child aggression are the most widely studied predictors of this phenomenon. The aim of the present study was to analyze whether parental use of corporal punishment affects peer victimization through child aggression. This mediation model was explored for both mothers and fathers and for both physical and relational forms of aggression and peer victimization. Furthermore, we also analyzed whether the mediation models were moderated by the sex of the child. Participants were 234 third graders (46% girls). Child aggression and victimization were measured by peers using the Mini Direct Indirect Aggression Inventory. Independent measures of mother’s and father’s use of corporal punishment were obtained from a PCA of items from the Parental Styles and Dimensions Questionnaire (PSDQ). Conditional process modeling was carried out using a macro for SPSS developed by Hayes (2013). Results indicated that aggression mediated the relation of parental corporal punishment to peer victimization. Some interesting moderating effects of sex in this mediation model were found; specifically, physical, and relational aggression mediated the relation of maternal corporal punishment to peer victimization only in boys. Few studies to date have addressed the connection between aggressive behavior and peer victimization as outcomes of corporal punishment, taking into consideration the role of parent’s and child’s sex, and both physical and relational forms of aggression and victimization during childhood.

Resiliency in Young Adulthood and Associations among Retrospective Peer Victimization and Internalizing Problems.

The social-ecological diathesis-stress model and related empirical work suggests that individuals who experienced peer victimization in childhood are at risk of revictimization and internalizing problems in young adulthood. The current study examined the association between retrospective and current reports of traditional and cyber victimization and internalizing problems, and the buffering effect of resiliency among 1141 young adults. Results indicated that retrospective traditional victimization was positively associated with current traditional and cyber victimization. Retrospective cyber victimization, however, was positively associated with current cyber victimization only. Retrospective traditional and cyber victimization were positively associated with internalizing problems while controlling for current victimization for both males and females. Resiliency buffered the positive association between retrospective cyber victimization, but not traditional victimization, and current internalizing problems. Findings suggest that retrospective accounts of peer victimization may have a lasting impact on symptoms of depression and anxiety for young adults, regardless of current victimization experiences. Longitudinal studies are needed to examine the associations among revictimization and mental health, and potential buffering mechanisms, among young adults.

A latent class analysis of parent-child discrepancies in reports of peer victimization: Associations to child sexual abuse status and psychological adjustment.

Researchers face an important challenge when assessing peer victimization in children, since self-reports are often discrepant with parent-reports. A latent class analysis identified patterns of response to items assessing peer victimization, which were either divergent or convergent between the parent and the child. Classes were then compared on the child sexual abuse status and on various behavioral and social outcomes. Participants were 720 school-aged child victims of sexual abuse and a comparison group of 173 nonvictims and their caregivers. We identified two discordant subgroups (self-identified and parent-identified) and two concordant groups (nonvictims and concordant victims of peer victimization). Compared to children of the comparison group, sexually abused children were five times more likely to be identified as targets of peer victimization solely by their parent than the contrary. Sexually abused children with concordant reports of peer victimization showed the poorest adjustment on all studied outcomes assessed 6 months later. Children who discounted experiencing peer victimization while their parent reported it were also at risk of maladjustment. Results underscore the importance of supplementing self-reports with other available sources of information, especially in young and vulnerable populations who may be inclined to discount their victimization experiences.

Peer Victimisation in Early Childhood; Observations of Participant Roles and Sex Differences

During middle childhood and adolescence, victimisation appears to be a group process involving different participant roles. However, peer reports with younger children (four to six years old) have failed to identify the participant roles of assistant (to the bully) reinforcers or defenders with much reliability. This may be because peer victimisation is a more dyadic process among younger children (behavioural reality), or because of limitations in young children’s cognitive capacity to identify these behaviours (cognitive limitations). The findings of an observational study which examined the group nature of peer victimisation among young children are presented. Observations were made of 56 children aged four and five years using time sampling during free play at school (totalling 43.5 h of observation). Records were made of their behaviour when an onlooker witnessed aggression by others, and also of others’ behaviour when they were being aggressive or being victimised. Although children other than the aggressor and target were present in nearly two thirds of the episodes of peer victimisation observed, few exhibited behavioural responses in line with the assistant, reinforcer or defender roles. This supports the behavioural reality rather than the cognitive limitations explanation. Sex differences were observed in types of aggression displayed by children, with boys more likely than girls to be physically aggressive. Children were less likely to be aggressive to other-sex peers and were most likely to be victimised by children of the same sex as them. There were also sex differences in children’s onlooker behaviour. The implications for our understanding of the development of peer victimisation and bullying in children are discussed.

Okulöncesi Eğitime Devam Eden Atipik ve Tipik Gelişim Gösteren Çocukların Saldırganlıklarının ve Akran Şiddetine Maruz Kalma Düzeylerinin Belirlenmesi

The present study aimed to determine aggression and exposure to peer victimization levels of children attending preschool education and displaying atypical and typical development. The study group consisted of 60 children with atypical and 60 with typical development who attended inclusive education activities in state kindergartens and preschools affiliated to primary education in Burdur and Isparta and the town of Soma in Manisa district. The data was collected using The Child Behavior Scale developed by Ladd and Profilet (1996), The Peer Victimization Scale developed by Ladd and Kochenderfer (2002), and the Personal Information Form developed by the researcher. The data were analyzed using correlation calculations with Mann Whitney U and Two-Factor ANOVA techniques on SPSS 16.0. At the end of the study, a positive relation was found between aggression and exposure to preschool children's peer victimization levels displaying atypical and typical development. The aggression level of children with atypical and typical development increases parallel with their exposure to peer victimization. No significant relation was found between atypically and typically developing children’s aggression and exposure to peer victimization levels and their genders and age groups. Moreover, levels of exposure to peer victimization did not differ by children’s state of having atypical or typical development.
