Trajectories of peer victimization among left-behind children in rural China: The role of positive school climate.

Left-behind children are likely to experience peer victimization, which can have detrimental consequences in their developmental outcomes. Yet, limited longitudinal research have examined peer victimization trajectories over time or the factors associated with left-behind children in China. The purpose of the present study was to examine what, if any, distinct trajectories of peer victimization exist among left-behind children and whether these trajectories are related to school climate, left-behind status, and their interactions. Participants were 853 Chinese left-behind children (Mage = 14.25, SD = 2.39; 43.4% girls) who participated in a four-wave longitudinal study conducted in rural China. Participants reported school climate (indexed by safety and order, acceptance and support, equality and fairness, autonomy and cooperation) at T1 and peer victimization across T1 to T4 spanning 2 years. Latent class growth analyses identified four peer victimization trajectories, including a stably low-decreasing group, a moderate-decreasing group, a high-decreasing group, and an increasing group. Multinomial logistic regression analyses revealed that children who perceived more positive school climate were more likely to exhibit a stably low-decreasing trajectory compared to the other three groups. In addition, among left-behind children who perceived more positive school climate, children with single-parent migrating were more likely to be members of the stably low-decreasing group as compared to those with both-parent migrating. Peer victimization among left-behind children is a concern especially for those who were left behind by both parents and perceived less positive school climate. Targeted school-based interventions and services focused on reducing peer victimization and improving school climate are needed for left-behind children, especially those with both-parent migrating.

Concurrent and longitudinal associations of developmental language disorder with peer victimization in adolescence: evidence from a co-twin study.

Children with developmental language disorder (DLD) experience higher levels of peer victimization than their peers. However, it is not known if such associations reflect genetic and environmental confounding. We used a co-twin control design to investigate the association of language difficulties (DLD and separately poor pragmatic language) with peer victimization and compare the developmental trajectories of peer victimization across adolescence for those with and without language difficulties. Participants were 3,400 pairs of twins in the Twins Early Development Study (TEDS), a UK-based population birth cohort. Language abilities were assessed via online tests at age 11 and peer victimization was self-reported at ages 11, 14 and 16. Language difficulties were defined as language abilities at least -1.25 SD below the mean of the TEDS sample. We performed linear regressions and latent growth curve modeling at a population level and within monozygotic and same-sex dizygotic twin pairs. At population level, youth with DLD experienced higher levels of peer victimization at ages 11 (β = 0.27, 95% Confidence Interval (CI) 0.20-0.35), 14 (β = 0.15, 95% CI 0.03-0.27) and 16 (β = 0.17, 95% CI 0.03-0.32) and a sharper decline in peer victimization between ages 11 and 16 compared to their peers without DLD. The associations between DLD and peer victimization were reduced in strength and not statistically significant in within-twin models. Moreover, there was no difference in the rate of change in peer victimization between twin pairs discordant for DLD. Results were similar for the association of poor pragmatic language with peer victimization. Associations between language difficulties (DLD and separately, poor pragmatic language) and peer victimization were confounded by genetic and shared environmental factors. Identifying specific factors underlying these associations is important for guiding future work to reduce peer victimization among adolescents with language difficulties.

Peer victimization trajectories and their relationships with depressive symptoms and externalizing problems: Risk enhancement or risk susceptibility

Peer victimization trajectories and their relationships with depressive symptoms and externalizing problems: Risk enhancement or risk susceptibility

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.

Interactive effects of coping strategies and emotion dysregulation on risk for peer victimization

The aim of the current longitudinal study was to examine the interactive effects of six common coping strategies (i.e., adult support seeking, friend support seeking, problem solving, humor, passive coping, and cognitive distancing) and emotion (i.e., anger and sadness) dysregulation on concurrent levels and subsequent trajectories of peer victimization over a 2-year period. Participants were 287 predominantly Caucasian students (53.7% boys; ages 6–9) from an elementary school located in the Midwestern United States. Self-reported coping strategies and emotion dysregulation were assessed at baseline; children also provided ratings of peer victimization annually over a 2-year period. Results indicated that the effectiveness of particular coping strategies may depend on children's overt, undercontrolled displays of anger and sadness. Consistent with recent recommendations, these findings suggest that some youth may require interventions that focus on both enhancing emotion regulation skills and teaching strategies for responding to peer victimization in a more adaptive manner.

The Role of Pubertal Timing in the Development of Peer Victimization and Offending From Early- to Mid-Adolescence

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of Swedish adolescents ( N = 1,515, 51% girls, [Formula: see text]age at T1 = 13.0 years). The results revealed negative developmental trends for peer victimization and offending. Early pubertal timing was linked to higher initial levels and a steeper decrease of peer victimization and offending. The only effect of pubertal timing that differed between the genders was that the initial level of offending was stronger for boys than girls. In conclusion, the negative impact of early pubertal timing on peer victimization and offending occurs in the early stages of adolescence and disappears thereafter.

Social status and friendship in peer victimization trajectories

Background/Objective: Most studies have evaluated victimization at a single time point, making it difficult to determine the impact of the time during which an individual is victimized. This longitudinal study aims to examine the differences in the levels of social status (social preference and perceived popularity) and friendship in peer victimization trajectories, and to analyse if there were changes over time in the levels of social status and friendship in each trajectory. Method: The final sample was composed of 1,239 students (49% girls) with ages between 9 and 18 (M = 12.23, SD = 1.73), from 22 schools in southern Spain. Peer nominations were collected. Results: The General Linear Model results associated the highest levels of social preference, perceived popularity and friendship with the sporadic victimization profile and the lowest levels of these dimensions with the stable profile. Conclusions:The results are discussed based on important personal aspects of stable victimization that confirms social rejection, unpopularity, and the low social support that victimization causes. This contribution is discussed in terms of health and social welfare in adolescence.

Early Childhood Factors Associated With Peer Victimization Trajectories From 6 to 17 Years of Age.

To describe (1) the developmental trajectories of peer victimization from 6 to 17 years of age and (2) the early childhood behaviors and family characteristics associated with the trajectories. We used data from 1760 children enrolled in the Quebec Longitudinal Study of Child Development, a population-based birth cohort. Participants self-reported peer victimization at ages 6, 7, 8, 10, 12, 13, 15, and 17 years. Participants' behavior and family characteristics were measured repeatedly between ages 5 months and 5 years. We identified 4 trajectories of peer victimization from 6 to 17 years of age: low (32.9%), moderate-emerging (29.8%), childhood-limited (26.2%), and high-chronic (11.1%). Compared with children in the low peer victimization trajectory, children in the other 3 trajectories were more likely to exhibit externalizing behaviors in early childhood, and those in the high-chronic and moderate-emerging trajectories were more likely to be male. Paternal history of antisocial behavior was associated with moderate-emerging (odds ratio [OR] = 1.54; 95% confidence interval [CI] = 1.09-2.19) and high-chronic (OR = 1.93; 95% CI = 1.25-2.99) relative to low peer victimization. Living in a nonintact family in early childhood was associated with childhood-limited (OR = 1.48; 95% CI = 1.11-1.97) and high-chronic (OR = 1.59; 95% CI = 1.09-2.31) relative to low peer victimization. Early childhood externalizing behaviors and family vulnerabilities were associated with the development of peer victimization. Some children entered the cascade of persistent peer victimization at the beginning of primary school. Support to these children and their families early in life should be an important component of peer victimization preventive interventions.

Exploring Early Childhood Factors as an Avenue to Address Chronic Peer Victimization.

Most youth experience peer victimization, and when chronic, it can lead to problems related to social-emotional development,1 peer relationships,1 and school engagement.2 In their study, “Early Childhood Factors Associated With Peer Victimization Trajectories from 6 to 17 Years of Age,” Oncioiu et al3 investigate peer victimization over time, beginning with the first years of school. This study is one of the largest and most extensive studies ever conducted on this topic. The authors use a repeated-measure, person-centered approach that allows for the comparison of personal trajectories over time and for causal inferences to be drawn. Four developmental trajectories of peer victimization are uncovered. Approximately one-third of children are in the low-victimization trajectory. The remaining two-thirds of children are in either the high-chronic (11%) trajectory, in which victimization is persistently higher than peers; the childhood-limited (26%) trajectory, in which early childhood victimization decreases by adolescence; or the moderate-emerging (30%) trajectory, in which victimization levels are moderate, remaining relatively steady and above normative levels, compared with those in the low-victimization trajectory across childhood and adolescence. Given that nearly two-thirds of school-aged youth in the current study report peer victimization during elementary and/or middle school, … Address correspondence to Stephen S.

Associations between developmental trajectories of peer victimization, hair cortisol, and depressive symptoms: a longitudinal study.

Peer victimization has been associated with long-lasting risks for mental health. Prior research suggests that stress-related systems underlying adaptation to changing environments may be at play. To date, inconsistent findings have been reported for the hypothalamic-pituitary-adrenal (HPA) axis, and its end product cortisol. This study tested whether peer victimization was associated with hair cortisol concentrations (HCC), and whether this association varied according to sex, timing, and changes in exposure. We also examined whether peer victimization differentially predicted depressive symptoms according to HCC. The sample comprised 556 adolescents (42.0%; 231 males) who provided hair for cortisol measurement at 17years of age. Peer victimization was reported at seven occasions between the ages of 6 and 15years. Peer victimization was nonlinearly associated with HCC for boys only, whereas changes in peer victimization were related to HCC for boys and girls. Peer victimization predicted more depressive symptoms for all participants, except those with lower HCC. Our findings provide further support for persistent dysregulation of the HPA axis following exposure to chronic adversity, of which the expression may change according to sex and the severity of victimization.

Childhood trajectories of peer victimization and prediction of mental health outcomes in midadolescence: a longitudinal population-based study

Exposure to peer victimization is relatively common. However, little is known about its developmental course and its effect on impairment associated with mental illnesses. We aimed to identify groups of children following differential trajectories of peer victimization from ages 6 to 13 years and to examine predictive associations of these trajectories with mental health in adolescence. Participants were members of the Quebec Longitudinal Study of Child Development, a prospective cohort of 2120 children born in 1997/98 who were followed until age 15 years. We included 1363 participants with self-reported victimization from ages 6 to 13 years and data available on their mental health status at 15 years. We identified 3 trajectories of peer victimization. The 2 prevailing groups were participants with little or moderate exposure to victimization (441/1685 [26.2%] and 1000/1685 [59.3%], respectively); the third group (244 [14.5%]) had been chronically exposed to the most severe and long-lasting levels of victimization. The most severely victimized individuals had greater odds of reporting debilitating depressive or dysthymic symptoms (odds ratio [OR] 2.56, 95% confidence interval [CI] 1.27-5.17), debilitating generalized anxiety problems (OR 3.27, CI 1.64-6.51) and suicidality (OR 3.46, CI 1.53-7.81) at 15 years than those exposed to the lowest levels of victimization, after adjustment for sex, childhood mental health, family hardship and victimization perpetration. The association with suicidality remained significant after controlling for concurrent symptoms of depression or dysthymia and generalized anxiety problems. Adolescents who were most severely victimized by peers had an increased risk of experiencing severe symptoms consistent with mental health problems. Given that peer victimization trajectories are established early on, interventions to reduce the risk of being victimized should start before enrolment in the formal school system.

Peer victimization trajectories from kindergarten through high school: Differential pathways for children’s school engagement and achievement?

This investigation’s aims were to map prevalence, normative trends, and patterns of continuity or change in school-based peer victimization throughout formal schooling (i.e., Grades K–12), and determine whether specific victimization patterns (i.e., differential trajectories) were associated with children’s academic performance. A sample of 383 children (193 girls) was followed from kindergarten (Mage = 5.50) through Grade 12 (Mage = 17.89), and measures of peer victimization, school engagement, academic self-perceptions, and achievement were repeatedly administered across this epoch. Although it was the norm for victimization prevalence and frequency to decline across formal schooling, 5 trajectory subtypes were identified, capturing differences in victimization frequency and continuity (i.e., high-chronic, moderate-emerging, early victims, low victims, and nonvictims). Consistent with a chronic stress hypothesis, high-chronic victimization consistently was related to lower—and often prolonged—disparities in school engagement, academic self-perceptions, and academic achievement. For other victimization subtypes, movement into victimization (i.e., moderate-emerging) was associated with lower or declining scores on academic indicators, and movement out of victimization (i.e., early victims) with higher or increasing scores on these indicators (i.e., “recovery”). Findings provide a more complete account of the overall prevalence, stability, and developmental course of school-based peer victimization than has been reported to date.

Peer Victimization Trajectories at the Adolescent Transition: Associations Among Chronic Victimization, Peer-Reported Status, and Adjustment

The current study demonstrated that chronic peer victimization, as compared to time-limited victimization, is particularly associated with peer status and peer-reported adjustment at the adolescent transition. Using a cohort sequential design, a sample of 653 adolescents (48% female, 87% Caucasian) in Grades 6–8 were assessed at 3 annual time points; data captured indices of peer victimization, likeability, popularity, and several peer-reported indices of internalizing (e.g., sadness, worry) and externalizing (e.g., anger, fighting) symptoms across Grades 6–10. Four trajectories of victimization experiences were identified—chronic, high decreasing, low increasing, and low stable—suggesting instability in victimization experiences over time. Adolescents who experienced chronic victimization, as compared to those with low-stable, decreasing, or increasing levels of victimization, were rated by peers more often on indices of maladjustment and less often on measures of popularity and likeability. Findings highlight negative associations with chronic victimization and underscore the need for targeted interventions to prevent chronic victimization. Overall, findings further emphasize the role of chronicity in victimization and highlight the importance of identifying chronic victims for intervention and prevention efforts.

Personal and familial predictors of peer victimization trajectories from primary to secondary school.

Using a sample of 767 children (403 girls, 364 boys), this study aimed to (a) identify groups with distinct trajectories of peer victimization over a 6-year period from primary school through the transition to secondary school, and (b) examine the associated personal (i.e., aggression or internalizing problems) and familial (family status, socioeconomic status, the parent-child relationship) predictors. Peer victimization was assessed via self-reports from Grades 4 through 9 (ages 10 through 15 years), aggression and internalizing problems were assessed in Grade 4 via peer nominations, and the parent-child relationship was assessed in Grade 7 (i.e., right after the transition to secondary school) via parent-reports. Growth Mixture modeling revealed 1 group (62%) who experienced little victimization in primary school and even less in secondary school, another group (31%) who was victimized in primary but not or much less in secondary school, and a third group (7%) who was chronically victimized in both school contexts. Boys were more likely than girls to follow any elevated victimization trajectory. Chronic victimization across primary and secondary school was predicted by nonintact family status and a combination of both internalizing problems and aggression compared with nonvictimized youth. In contrast, transitory victimization during primary but not in secondary school was predicted by aggression, but not internalizing problems. Support as well as conflict in the parent-child relationship also showed significant, albeit distinct associations with the different peer victimization trajectories. (PsycINFO Database Record

Developmental Trajectories of Peer Victimization: Off-line and Online Experiences During Adolescence

This study investigated the development and consequences of off-line and online victimization during adolescence. We examined the number and shapes of off-line and online victimization trajectories, the relationship between trajectories of off-line and online victimization, and their effect on life satisfaction. A four-wave panel study with 6-month time intervals was conducted among a representative sample of Dutch adolescents aged 12-17 years (N = 1,762). We used group-based modeling to investigate the victimization trajectories. Three off-line victimization trajectories could be distinguished. One group followed a trajectory of low to no victimization experiences across adolescence. A second group followed a pathway of moderate and decreasing victimization. A third group followed a pathway of high and decreasing victimization. Two groups in online victimization could be distinguished. One group followed a trajectory of low to no victimization experiences. A second group followed a pathway of moderate victimization that peaked at age 14. Dual-trajectory analyses revealed a substantial overlap between off-line and online victimization trajectories. Finally, victimization and life satisfaction were longitudinally related; moderate and high victimization trajectories resulted in lower levels of life satisfaction during wave 4. The overlap between the off-line and online victimization trajectories and their negative consequences on life satisfaction suggests that prevention of victimization should focus on both types of victimization. The results suggest that peer victimization should not be studied without considering adolescent peer relationships on the Internet.

Parental strategies and trajectories of peer victimization in 4 to 5 year olds

This study was designed to examine how parental strategies contribute to explaining trajectories of peer victimization in young children. A total of 73 4 and 5 year old children identified as victims of peer aggression in the fall semester and their parents were recruited from 46 classrooms in 18 schools in the Netherlands. All children were followed-up twice in order to determine for whom victimization was stable. Hypothetical vignettes describing various forms of victimization were presented to one parent of each child in order to assess parental responses to victimization events. Findings indicated that autonomy supporting and autonomy neutral strategies were associated with a decrease of victimization in the first semester of the school year. No protective effects were found in the second semester. Autonomy undermining strategies were not related to the course of peer victimization. These findings underscore the importance of joint and coordinated efforts of teachers and parents as partners in supporting victimized young children at school.

Peer victimization trajectories and their association with children’s affect in late elementary school

The current study examined peer victimization trajectories for 1528 children from third to fifth grade and the association of those trajectories to children’s positive and negative affect. On average, victimization was low to moderate and remained stable (self-report) or increased (peer-reports). In addition, five distinct trajectories were identified based on self-report: Low, Moderate, Increasing, Decreasing, and Chronic. Peer-reported victimization did not reveal distinct trajectories. Although the level of victimization was related to concurrent negative affect (self- and peer-reported victimization) and to positive affect (self-report victimization only), relations between change in victimization and change in affect were less consistent. Also, a chronic victimization trajectory was associated with greatest affective distress and a decreasing trajectory was associated with partial, but not full, recovery in terms of affect. Results largely support a chronic model of victimization’s effects in which victimization has compounding and enduring effects on adjustment. Intervention implications include the importance of including selective interventions for highly victimized youth with universal anti-bullying programs, assessing both past and current victimization, and including indicators of adjustment when evaluating anti-bullying interventions.

Trajectories of Peer Victimization: The Role of Multiple Relationships.

This study examined early elementary school children's trajectories of peer victimization with a sample of 218 boys and girls. Peer victimization was assessed (via peer report) in kindergarten, 1(st), 2(nd), and 5(th) grades. Hierarchical linear modeling (HLM) was used to examine multiple types of relationships (mother-child, student-teacher, friendship) as predictors of kindergarten levels of peer victimization and changes in peer victimization across time. Results indicated that the mother-child relationship predicted kindergarten levels of peer victimization, and that the student-teacher relationship did not provide additional information, once the mother-child relationship was accounted for in the analyses. Friendship predicted changes in peer victimization during the elementary school years. Results are discussed in a developmental psychopathology framework with special emphasis on the implication for understanding the etiology of peer victimization.
