Association Between Peer Victimization, Gender Diversity, Mental Health, and Recurrent Headaches in Adolescents: A Canadian Population-Based Study.

It is unknown whether bullying and gender diversity are associated with increased headache frequency in adolescents. Our study aimed to assess the association between peer victimization, gender diversity, and frequent recurrent headaches in adolescents, while controlling for age, sex, socioeconomic status, and potential confounders (mood and anxiety disorders, suicidality). This was a cross-sectional observational study of adolescents aged 12-17 years using data from a Canadian population-based health survey. Headache frequency was dichotomized into "≤once/wk" or ">once/wk" (i.e., frequent recurrent headaches). Logistic regression was used to quantify the association between frequent peer victimization (overt or relational), gender diversity (female sex at birth + male gender, male sex at birth + female gender, or gender diverse), mood/anxiety disorder, suicidality, and the odds of frequent recurrent headaches. The fully adjusted multivariable logistic regression model included all exposures and was controlled for age, sex, and socioeconomic status. Bootstrap replicate weighting was used to account for survey design effects. There were an estimated 2,268,840 eligible participants (weighted sample size) (mean age = 14.4 years, 48.8% female, 0.5% gender diverse), and 11.2% reported frequent recurrent headaches. Frequent recurrent headaches were associated with older age (odds ratio [OR] = 1.26 per year of age, 95% CI 1.20-1.31), female sex (OR = 2.89, 95% CI 2.47-3.37), and being gender diverse (OR = 3.30, 95% CI 1.64-6.63, adjusted for age/sex). Youth with frequent headaches had higher odds of experiencing both overt and relational bullying compared with peers (OR = 2.69, 95% CI 2.31-3.14, and OR = 3.03, 95% CI 2.58-3.54, adjusted for age/sex). In the fully adjusted model, frequent headaches were no longer associated with gender diversity (OR = 1.53, 95% CI 0.63-3.69) but were still associated with frequent overt and relational peer victimization (OR = 1.82, 95% CI 1.41-2.34, and OR = 1.54, 95% CI 1.17-2.03, respectively), suicidality (OR = 1.83, 95% CI 1.44-2.32), and having a mood or anxiety disorder (OR = 1.50, 95% CI 1.01-2.21, and OR = 1.74, 95% CI 1.24-2.45, respectively). In a model adjusted for age, sex, and mood/anxiety disorders, the risk of suicidality increased incrementally with headache frequency. Peer victimization and suicidality may be associated with higher headache frequency in adolescents with headaches, independently of mood and anxiety symptoms. Gender-diverse adolescents may have a higher risk of experiencing frequent headaches when compared with cisgender peers, and this may be explained by associated psychosocial factors (anxiety, depression, suicidality, and peer victimization).

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

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. 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. 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. 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.

Relational Peer Victimization as a Predictor of Academic Engagement.

Peer victimization can be detrimental to youth. This study examines a particular type of peer victimization, relational peer victimization, and its effect on students' engagement in the classroom. We specifically investigate the longitudinal relationship between relational peer victimization and academic engagement in a sample of 204 Black 3rd through 5th grade elementary school students by utilizing multiple informants: students and their parents reported on relational peer victimization, and teachers reported on students' academic engagement. Our findings showed convergence between student and parent reports of relational peer victimization and revealed that experiencing relational peer victimization during the beginning of the school year (fall) negatively predicts teacher reported academic engagement towards the end of the school year (spring). Our study suggests that relational peer victimization is a critical issue that educators and researchers should consider when trying to foster academic engagement. There is also a need for further research regarding the role that families play in providing support to Black relationally victimized youth.

Can school climate or peer preference moderate the adjustment difficulties associated with peer victimization among Chinese middle school students?

Most research on peer victimization has focused on Western samples, but in recent years peer victimization in China has become more prevalent. As a result, limited information is available on how peer victimization, school climate, peer preference, and adjustment difficulties impact Chinese middle school students. This cross-sectional study explored these relations. With a sample of 734 7th and 8th-grade students (54.1% male, 45.8% female) from two middle schools in Beijing, China, findings revealed that peer victimization and peer preference predicted adjustment difficulties; however, school climate did not. Although peer preference was not a significant moderator of the association between peer victimization and adjustment difficulties, school climate significantly moderated the relation between relational peer victimization and adjustment difficulties. Limitations, future directions, and implications are further discussed.

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.

Exploring joint HPA-inflammatory stress response profiles in adolescent girls: Implications for developmental models of neuroendocrine dysregulation.

Prior research has struggled to differentiate cortisol stress response patterns reflective of well-regulated versus dysregulated hypothalamic-pituitary-adrenal (HPA) axis function among adolescents. Here, we show how exploring profiles of joint HPA-inflammatory stress responsivity, and linking those profiles to pubertal development and peer stress exposure may aid such distinction. Adolescent girls (N=157, Mage =14.72 years, SD=1.38) at risk for psychopathology completed assessments of salivary cortisol and pro-inflammatory cytokines (i.e., tumor necrosis factor-α, interleukin-1β, and interleukin-6) prior to and following the Trier Social Stress Test. Adolescents, a close friend, and a caregiver completed questionnaire measures of peer stress and pubertal status. Multitrajectory modeling of adolescents' cortisol and cytokine levels revealed three profiles: low cortisol response-stably low cytokine (n=75), high cortisol response-stably moderate cytokine (n=47), and low cortisol response-stably high cytokine (n=35). Relative to low cortisol response-stably low cytokine, adolescents exhibiting the high cortisol response-stably moderate cytokine profile were more advanced in their pubertal development, but presented with similarly low levels of peer stress exposure. Despite showing cortisol responses that were indistinguishable from low cortisol response-stably low cytokine, adolescents exhibiting the low cortisol response-stably high cytokine profile were more pubertally advanced, but also more likely to have experienced chronic peer strain (self-report) and relational peer victimization (close friend-report). These findings thus illustrate the potential value of taking a multisystem approach to studying adolescent stress responsivity and underscore the importance of considering developmental and social factors when interpreting cortisol stress response patterns. Ultimately, such work may help inform developmental models of neuroendocrine dysregulation and related risk for psychopathology.

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.

Forms of peer victimization in adolescence: Covariation with symptoms of depression.

Peer victimization is a common concern in adolescence that includes both relational (e.g., exclusion, rumor spreading) and overt (e.g., hitting, threatening) forms (Crick & Bigbee, 1998). Relational and overt peer victimization have shown to be differentially associated with depressive symptoms, with relational peer victimization showing a stronger association to depressive symptoms than overt peer victimization (Casper & Card, 2017). The current study uses an accelerated longitudinal research design to investigate: (a) how relational and overt peer victimization and depressive symptoms change over an accelerated age period from 11.1 to 16.8 years (centered at 12.5 years), and (b) concurrent and prospective associations of relational and overt peer victimization with depressive symptoms. Gender differences are investigated. Participants included 1,434 adolescents in grades 7 to 9 (53.5% girls; Mage = 13.5 years, SD = .9) who were assessed over 2 school years. Adolescents were from diverse ethnic groups (45% racialized groups) and from low- to middle-income households. Adolescents reported the frequency of their experiences of relational and overt peer victimization (Crick & Grotpeter, 1996) and depressive symptoms (Bevans et al., 2012) in the fall and spring of each school year. Both forms of peer victimization and depressive symptoms increased from age 12.5 to age 14 before decreasing by age 16.8 years. Frequency of relational peer victimization at age 12.5 was related to depressive symptoms at age 16.8. Frequency of depressive symptoms at age 12.5 predicted change in both forms of peer victimization at age 16.8. Some gender differences were observed.

The moderating role of pessimism in the association between retrospective relational peer victimization, interpersonal risk factors, and suicide ideation.

Peer victimization (PV) is a serious concern for youth and is associated with subsequent suicide ideation in young adulthood. The interpersonal theory of suicide may provide a framework for understanding suicide ideation in this population. Specifically, thwarted belongingness (TB) and perceived burdensomeness (PB) have been significantly associated with suicide ideation among young adults with a history of peer victimization. Additionally, the personality trait of pessimism is associated with elevated suicide ideation. Thus, this study tested the association between self-reported frequency of retrospective relational (i.e., verbal and indirect) PV in primary and secondary school, thwarted interpersonal needs (TB and PB), and current suicide ideation, as well as how these relations may vary based on current pessimism. Participants were 330 undergraduate students. Nonparametric bootstrap moderated mediation procedures were used to test hypotheses. Results indicated significant indirect effects of frequency of retrospective relational PV and suicide ideation through PB and TB. Contrary to predictions, results did not indicate significant moderated mediation; however, the association between PB and suicide ideation was stronger at lower pessimism levels. We also provide supplemental analysis with optimism as the moderator. These findings suggest that clinicians may consider targeting TB, PB, as well as pessimism and optimism among those with a history of relational PV when assessing and intervening on current suicide ideation. Implications, limitations, and future directions are further discussed.

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.

Extracurricular activities and peer relational victimization: Role of gender and school social norms

ABSTRACT Participation in extracurricular activities is associated with positive developmental indicators and wellbeing. However, involvement in some activities may place adolescents at-risk for peer victimization. This study focuses on the effect of participating in sports and academic/arts extracurricular activities on relational victimization, focusing on the role that gender (stereotypical activities for boys and girls) and school norms (proportion of participation) might have in this association. The study uses data from the Chilean National Survey on Violence in the School Context (ENVAE, 2014), considering a national representative sample of 38,286 7th to 12th graders. Results indicate that for boys breaking school social norms is associated with experiencing victimization, whereas for girls breaking gender norms increases their likelihood of being victimized. Implications for research and intervention are discussed.

Verbal, physical, and relational peer victimization: The role of immigrant status and gender.

Most studies suggest that immigrant youth are more likely to be victimized than their non-immigrant counterparts. In Italy, a country in which the number of foreign migrants has grown exponentially over recent decades, this line of research is particularly interesting. Thus, the main objective of the present study was to examine the relationship between peer victimization, gender, and immigrant status in a large sample of students. The research used data from a cross-sectional Italian survey on the "Integration of Second Generations", which was administered to 68,127 students in grades 6 through 13 (49% female; 47% immigrant). Multinomial logistic regression analyses were used to examine the association between immigrant status and gender with verbal, physical, and relational victimization, after adjusting for socio-demographic variables. Immigrant and male participants were more likely to be classified as frequently victimized. The significant interaction effect between immigrant status and gender revealed that male immigrant students were more likely to belong to the frequently relationally victimized category compared to their counterparts. The study highlights the importance of including immigrant status disparities in peer victimization research. Prevention efforts and intervention strategies should be implemented to create safe environments in Italy.

Relational Peer Victimization Interacts With Depression Severity to Predict the Timing of Alcohol Use Initiation in Adolescent Girls.

Peer victimization is consistently linked to adolescents' alcohol use. However, the relative influence of relational and physical peer victimization on alcohol use, and timing of drinking initiation, is not well understood. In this study, we evaluate the impact of both relational and physical peer victimization on adolescent girls' alcohol use initiation, and the extent to which depression severity moderates these associations. Participants were 2,125 girls in the Pittsburgh Girls Study, a longitudinal community-based study. Participants reported experiences of relational and physical peer victimization, depression severity, and alcohol use each year from ages 10 to 17. Cox proportional hazards (PH) regression analyses predicting the timing of first drink were conducted in 2 stages, testing for main effects of peer victimization in Model 1 and moderation by depression severity in Model 2. Analyses were split at age 14 to adjust for PH violations. Model 1 results supported a main effect for relational (Hazards ratio [HR]=1.83, CI: 1.46 to 2.28≤age 13; HR=1.23, CI: 1.05 to 1.45≥age 14) but not physical victimization on timing of alcohol use onset (HR=1.10, CI: 0.88 to 1.39). Model 2 results show that depression severity moderates the association between relational victimization and alcohol use initiation: the association between relational victimization and early alcohol use onset was stronger for lower depression severity (-1 SD HR=2.38, CI: 1.68 to 3.39≤age 13; -1 SD HR=1.48, CI: 1.10 to 1.52≥age 14). Results demonstrate that relational (and not physical) victimization predicts earlier drinking among adolescent girls. Relational peer victimization conferred greater risk for alcohol use initiation when depression severity was lower, whereas girls with high depression severity engaged in early alcohol use regardless of peer victimization. Results suggest that interventions focused on relational peer victimization may have spillover effects for delaying girls' alcohol use initiation, particularly in early adolescence, when this association is most robust.

Direct and indirect pathways to early school adjustment: Roles of young children’s mental representations and peer victimization

We examined direct and indirect associations among preschool-age children’s attachment-related mental representations of mothers and peer relationships with their early school adjustment. One hundred and eighteen preschoolers attending Head Start programs were administered a story stem completion task to measure prosocial and antisocial themes in their attachment representations. Approximately two months later, teachers reported on children’s physical and relational peer victimization and prosocial attention from peers. Another three months later, trained observers rated preschoolers’ school adjustment. Children’s prosocial themes in their attachment-related mental representations were negatively related to reported experiences of physical and relational peer victimization. Physical peer victimization was associated with poorer school adjustment and prosocial attention from peers was associated with better school adjustment. Children’s prosocial themes in their attachment-related mental representations were indirectly associated with better school adjustment via lower physical peer victimization. We discuss the implications of these findings for future research and intervention on peer victimization in early childhood.

Heart rate (variability) and the association between relational peer victimization and internalizing symptoms in elementary school children.

Relational victimization typically emerges first during the elementary school period, and has been associated with increased levels of internalizing symptoms in children. Individual differences in autonomic nervous system functioning have been suggested as a potential factor linking social stressors and internalizing symptoms. The aim of this study was therefore to examine whether heart rate and heart rate variability mediated the association between relational victimization and internalizing symptoms in 373 mainstream elementary school children. Children were assessed in 2015 (T0; Grades 3-5, M age = 9.78 years, 51% boys) and reassessed in 2016 (T1). Heart rate and heart rate variability were assessed during a regular school day at T1. A multi-informant (teacher and peer report) cross-time measure of relational victimization, and a multi-informant (self- and teacher report) measure of internalizing problems at T1 was used. Results showed that heart rate variability, but not heart rate, mediated the association between relational victimization and internalizing symptoms. This study provides tentative support that in children from a general population sample, a psychobiological factor may mediate the association of relational victimization with internalizing symptoms.

Attentional avoidance in peer victimized individuals with and without psychiatric disorders

BackgroundAttentional biases are a relatively robust phenomenon among clinical populations but less pronounced in healthy participants. However, regarding the components of attentional biases and the directions of attention allocation, there are several inconsistencies in the literature. The present study examined whether these inconsistencies can be traced back to previous experiences of relational peer victimization in clinical populations.MethodsParticipants were subjects with a diagnosed psychiatric disorder (n = 30) and healthy controls (n = 31). Additionally, the sample was divided into two subgroups according to the participants’ reports of previous relational peer victimization (high peer victimization: n = 28; low peer victimization: n = 33). Attentional biases were measured by the Emotional Stroop task and a dot-probe task.ResultsIn both samples, peer victimized participants showed delayed response times when color-naming negative and positive compared to neutral adjectives in the Emotional Stroop task. Likewise, the dot-probe task indicated attentional avoidance of both negative and positive words in peer victimized participants with and without a psychiatric disorder. Interestingly, presence of a psychiatric disorder did not have a significant effect on attentional biases.ConclusionBoth tasks could detect that attentional processes were linked to the experience of peer victimization rather than to the current diagnostic status of the participants. Attentional avoidance of emotional stimuli may prevent victimized individuals from responding adequately to environmental stimuli, which may increase the risk for the development of psychopathology.

Peer victimization, aggression, and depression symptoms in preschoolers

Our primary aim was to test the developmentally-based interpersonal model of depression in preschool-age children. Socio-behavioural deficits (i.e., non-normative use of physical and relational aggression) were expected to interact with relationship disturbances (i.e., physical and relational peer victimization) in relation to depression symptoms in preschool-age children. We tested this theory using multiple regression in a sample of 198 preschool children (Mage 33.61 months, SDage = 5 months) using a multi-informant approach. Depression symptoms and physical aggression were measured by the Caregiver–Teacher Report form and relational aggression was measured by the Preschool Social Behaviour Scale. Physical and relational victimization were measured by the Preschool Peer Victimization Measure — Teacher Report and observations of peer victimization and aggression from the Early Childhood Play Project observation system. As a secondary aim, we examined the moderating role of sex. When children were relationally victimized by peers, engaging in high relational aggression was related to depression symptoms in the teacher-reported model; whereas physical aggression did not moderate the relation between physical peer victimization and depression symptoms. These findings were not replicated across reporters. No sex differences were found. Results supported the application of the developmentally-based interpersonal model of depression in preschool-aged children. Those experiencing relational victimization and engaging in relational aggression in preschool may be at risk for heightened concurrent depression symptoms.

Peer Victimization in Children With ADHD: A Community-Based Longitudinal Study

Objectives: To investigate (a) whether children with ADHD experience higher levels of overt and relational peer victimization (PV) than children without ADHD and (b) child, family, and school predictors of PV in children with ADHD. Method: 173 children with ADHD and 199 non-ADHD controls were recruited through 43 Melbourne schools at mean age 7.3 years. Parent- and teacher-reported PV (Social Experience Questionnaire) data were collected at mean age 8.9 years. Potential child, family, and school predictors of PV were measured at baseline. Results: Children with ADHD experienced higher levels of PV than children without ADHD by both parent- and teacher-report. Child predictors accounted for the greatest variance in PV, and the strongest predictors of PV were teacher-reported conduct problems, and medication use. Conclusion: Children with ADHD are at higher risk of PV compared with non-ADHD controls. Recognizing and addressing PV is important to reduce additional impairment in children with ADHD.

Experiences of physical and relational victimization in children with ADHD: The role of social problems and aggression.

The social risk factors for physical and relational peer victimization were examined within a mixed-gender sample of children with and without attention-deficit/hyperactivity disorder (ADHD). Participants were 124 children (ages 8-12 years; 48% boys), with 47% exhibiting sub-clinical or clinical elevations in ADHD symptoms. ADHD and oppositional defiant disorder (ODD) symptom counts were assessed based on parent- and teacher-reports; parents rated children's social problems and teachers rated children's use of physical and relational aggression and experiences of physical and relational victimization. A multiple mediator model was used to test whether there were indirect effects of ADHD or ODD symptoms on physical and relational victimization through social problems, physical aggression, or relational aggression. At the bivariate level, ADHD and ODD symptoms were both significantly associated with higher rates of physical and relational victimization. In the mediational model, there were significant indirect effects of ADHD symptoms on relational victimization via social problems, of ODD on relational victimization via relational aggression, and of ODD symptoms on physical victimization via physical aggression. Results suggest that there are distinct risk factors implicated in the physical and relational victimization of youth with ADHD and that the co-occurrence of ODD symptoms is important to assess. Clinical implications for addressing victimization in children with ADHD are discussed.

Past Peer Victimization and Current Adult Attachment in College Students

The authors examined the potential long‐term effects of peer victimization experiences during childhood on attachment quality in current adult relationships in a sample of 386 university students attending 2 northeastern universities. Findings included (a) no significant gender differences regarding verbal or relational peer victimization; (b) significant correlations between all forms of previous victimization; and (c) previous verbal and relational victimization predicting less stable adult attachments, with verbal victimization being more significant.
