A longitudinal path analysis of peer victimization, threat appraisals to the self, and aggression, anxiety, and depression among urban African American adolescents

Effects of peer victimization on cortical processing of social-evaluative stress in patients with major depressive disorder

Peer victimization contributes to the development of major depressive disorders (MDDs). While previous studies reported differentiated peripheral physiological responses in peer-victimized individuals with depression, little is known about potential alterations of cortical event-related potentials (ERPs) in response to social stimuli in depressive patients with a history of peer victimization. Using a social condition paradigm, the present study examined whether peer victimization alters conditioned cortical responses to potentially threatening social stimuli in MDD patients and healthy controls. In the task, we studied ERPs to conditioned stimuli (CSs), i.e. still images of faces, that were coupled to unconditioned socially negative and neutral evaluative video statements. Peer victimization was related to more pronounced P100 amplitudes in reaction to negative and neutral CSs. Attenuated P200 amplitudes in peer-victimized individuals were found in response to negative CSs. Cortical responses to CSs were not influenced by a diagnosis of MDD. The results suggest altered responsiveness to interpersonal information in peer-victimized individuals. Facilitated early processing of social threat indicators may prevent peer-victimized individuals from adaptive responses to social cues, increasing their vulnerability for depression.

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.

Distinct physiological responses to social-evaluative stress in patients with major depressive disorder reporting a history of peer victimization

Peer victimization is a risk factor for the development of major depressive disorders, but little is known about the mechanisms. This study examined whether peer victimization alters physiological and affective responses to potentially threatening social stimuli. For this purpose, reactions to socially evaluative stimuli of depressive patients and healthy controls with varying histories of peer victimization were compared. In a social conditioning task, we studied heart rate responses to unconditioned socially negative and neutral evaluative video statements, followed by the heart rate reactions to conditioned stimuli, i.e. still images of the faces of the same actors. Diagnosis of depression and peer victimization were both associated with a more pronounced heart rate deceleration in response to unconditioned stimuli, irrespective of valence. The effect of peer victimization was stronger in depressive patients than in healthy controls. However, heart rate responses to the CSs were not related to depression or peer victimization. The results indicate a hypervigilant processing of social stimuli in depressive patients reporting histories of peer victimization. This distinct processing may be associated with inappropriate behavioral and emotional responses to social challenges, putting individuals at risk for depressive symptoms.

Longitudinal associations between traditional and cyberbullying victimization and depressive symptoms among young Chinese: A mediation analysis

BACKGROUND

The impacts of bullying victimization on psychological health are long-lasting. However, the longitudinal mediating processes of the association between being bullied (traditionally and in a cyber context) and depressive symptoms of Chinese youth remain underexplored, including across the sexes.

OBJECTIVE

This study investigated the longitudinal association between bullying victimization and depressive symptoms, including the mediating effects of physical health, healthy lifestyles, sleep quality, and academic achievements. Different pathways from traditional bullying and cyberbullying victimization regarding depressive symptoms were also explored, with a comparison across the sexes.

PARTICIPANTS AND SETTING

Data were obtained from the China Education Panel Survey, and ninth graders aged approximately 15 years constituted the baseline cohort.

METHODS

The baseline data and longitudinal data at two- and five-year follow-ups, respectively, were evaluated to estimate structural equation models.

RESULTS

Baseline traditional bullying and cyberbullying victimization significantly predicted subsequent depressive symptoms at both follow-ups (P < 0.001). Being bullied also predicted worse healthy lifestyles, poorer sleep quality, and lower academic achievements (P < 0.05), all significantly correlated with the development of depressive symptoms (P < 0.001) regarding both bullying victimizations. Physical health was the mediator of the traditional bullying victimization-depressive symptoms linkage (P < 0.05). Female victims have a relatively higher risk of depression versus male victims, with different mediating pathways from victimization to depressive symptoms.

CONCLUSIONS

Our findings strengthen the evidence of a longitudinal association between bullying victimization and depressive symptoms, provide new explanations for mechanisms of mediation, and highlight the importance of long-term comprehensive mental health interventions for victims of bullying.

Cybervictimization and cyberbullying among college students: The chain mediating effects of stress and rumination

The popularity of the Internet has led to an increase in cybervictimization and cyberbullying. Many studies have focused on the factors influencing cybervictimization or cyberbullying, but few have researched the mechanism that mediates these phenomena. Therefore, in this study, we use a chain mediation model to explore the mechanisms of cybervictimization and cyberbullying. This research is based on the general aggression model and examines whether stress and rumination play a mediating role in the relationship between cybervictimization and cyberbullying among Chinese college students. This study included 1,299 Chinese college students (597 men and 702 women, M = 21.24 years, SD = 3.16) who completed questionnaires on cybervictimization, stress, rumination, and cyberbullying. Harman's one-factor test was used to analyze common method bias; mean and standard deviations were used to analyze the descriptive statistics, Pearson's moment correlation was used to determine the relationship between variables, and Model 6 of the SPSS macro examined the mediating effect of stress and rumination. The results indicate that rumination mediated the relationship between cybervictimization and cyberbullying. In addition, stress and rumination acted as a chain mediator in this association. These results have the potential to reduce the likelihood of college students engaging in cyberbullying as a result of cybervictimization, minimize the rate of cyberbullying among youths, and lead to the development of interventions for cybervictimization and cyberbullying.

Dimensions of Parenting and Children's Bullying Victimization: A Look at the Racial/Ethnic and Grade Level Differences

The associations between the various dimensions of parenting and adolescent bullying have been widely studied, but it is unclear whether these associations vary by race/ethnicity and grade. The current study utilized the Health Behavior in School-Aged Children data in the United States for the investigation. The findings show that supportive parenting and permissive parenting were negatively associated with bullying victimization. However, controlling parenting and neglectful parenting were positively associated with bullying victimization. The results further revealed that the dimensions of parenting were similarly associated with bullying victimization across racial/ethnic groups. Parenting was also similarly associated with bullying victimization for both middle and high school students, except for supportive parenting, where middle school students with more parental support reported less bullying victimization. The implications of the findings are discussed.

Negative School Gossip and Youth Adolescents' Mobile Phone Addiction: Mediating Roles of Anxiety and Experiential Avoidance

Being the target of negative school gossip, a form of relational aggression, has been shown to be associated with psychological and behavioral problems in youth adolescents. Based on the experience avoidance model, this study tested the association between negative school gossip and youth adolescents' mobile phone addiction, and the serial mediation roles of anxiety and experience avoidance in this relationship. Junior high school students (N = 837; ages 12-15; 50% girls) completed the Negative School Gossip Scale, Anxiety Scale, Acceptance and Action Questionnaire (AAQ-II), and Mobile Phone Addiction Scale in their classrooms. The results of regression-based analyses showed that after controlling for age and gender, (1) negative school gossip was significantly associated with mobile phone addiction; (2) anxiety and experience avoidance each significantly mediated this association; (3) anxiety and experience avoidance serially mediated this association. The results support the experience avoidance model and highlight emotional factors as an internal mechanism by which negative school gossip is associated with youth adolescents' mobile phone addiction. The results also have implications for preventing and reducing youth adolescents' mobile phone addiction.

The influence of family incivility on cyberbullying perpetration: A moderated mediation model

Previous research has extended the stress literature by exploring the relationship between family incivility and cyberbullying perpetration, yet relatively less attention has been paid to underlying psychological mechanisms between that relationship among university students. According to the Frustration-Aggression Theory, this study examined the relationships of family incivility, cyberbullying perpetration, negative emotions and neuroticism among Chinese university students. Data were collected from 814 university students (females, N = 423; Mage = 19.96 years, SD = 3.09). The results examined the mechanism through which family incivility was significantly related to cyberbullying perpetration through the mediation of negative emotions, suggesting a strong link of stressful life events to online aggression. In addition, high levels of neuroticism moderated the relationship between family incivility and cyberbullying perpetration, as well as that between family incivility and negative emotions. The study revealed the chronic and potential impact of family incivility, underlined the interaction between stressful life events and online aggression, and put forward the intervention strategies of cyberbullying among university students.

Internet-delivered cognitive processing therapy for individuals with a history of bullying victimization: a randomized controlled trial

The purpose of this randomized controlled trial was to test an internet-delivered version of cognitive processing therapy (CPT) for the psychological distress associated with bullying victimization. The sample comprised 52 adults (i.e. 69.20% women; mean age = 43.37 (SD = 12.47); 3.85% ethnic minority) who self-identified as having a lifetime history of bullying victimization. Participants were randomized into three groups, which received 12 sessions of internet-delivered, therapist-guided, and content-modified version of CPT, 12 sessions of internet-delivered and therapist-guided stress management (SM), or a waitlist. Treatment outcomes included maladaptive trauma appraisals, symptoms of posttraumatic stress disorder (PTSD), depression, general anxiety and stress, social anxiety, and anger. Hierarchical linear modeling was used to analyse the data. Findings indicated that CPT was effective in reducing the strength of maladaptive appraisals related to bullying victimization and symptoms of PTSD compared to the waitlist and SM. SM outperformed CPT and the waitlist in reducing symptoms of depression, general anxiety, and stress. In conclusion, the results of this trial suggest that internet-delivered CPT is effective for the psychological distress and maladaptive appraisals associated with bullying victimization but that adaptions might be needed to target more effectively symptoms of anxiety and depression.

Like me Back: Neural Correlates of Low Perceived Relational Value in Peer Victimized Youth

Perceived relational value describes the extent to which individuals consider themselves to be liked and valued. Given the salience of peer opinions in adolescence, perceived relational value is an important part of adolescents' developing self-concept. Here, we examined the neural correlates of youth's perceptions of their relational value in two independent samples (N = 33, M_age  = 13.71, SD = 2.71; N = 26, M_age  = 15.43, SD = 0.33). In both studies, peer victimization was associated with lower perceived relational value behaviorally and with altered frontostriatal connectivity when perceiving low relational value during fMRI. Our results suggest that peer victimization may lead youth to become biased about how they will be perceived socially and may disrupt connectivity between brain regions involved in responding to appetitive social stimuli.

Pathways from bullying victimization to suicidal thoughts among urban African American adolescents: Implications for nurse practitioners

PURPOSE

Children and adolescents who are victimized by their peers are at an elevated risk of suicidal thoughts and behaviors. Bullying and suicide are major public health concerns; however, studies have not fully addressed the link between peer victimization and suicidal behavior among urban African American youth. The current study proposed and explored the pathways from peer victimization to suicidal thoughts via internalizing behaviors (i.e., low self-esteem, depression, and hopelessness).

DESIGN AND METHODS

The sample consisted of 638 African American adolescents (aged 12-22) from low-income communities in Chicago's Southside. A path model using the structural equation model was employed, controlling for biological sex, age, and government assistance.

RESULTS

The study found that victims of bullying are likely to develop low self-esteem and depression, and depression can contribute to feelings of hopelessness, thereby increasing suicidal risks.

CONCLUSIONS

Understanding the pathways from bullying victimization to suicidal thoughts is beneficial for nurse practitioners who assess and provide services and treatment to adolescents.

PRACTICE IMPLICATIONS

Because of limited resources in urban schools, anti-bullying programs need to be cost-effective.

Victimization and Peer and Parents Attachment: The Mediating Effect of Regulatory Emotional Self-Efficacy

Studies of the Spanish adolescent population has concluded that victimization is related to lack of emotional regulation and impulse control. Therefore, if a victim is unable to recognize, understand and regulate their emotions, this can result in rejection by their peers. A cross-sectional study was conducted to examine regulatory emotional self-efficacy as a possible mediator in the association between peer and parents attachment and victimization. Adolescents (n = 563) completed Regulatory Emotional Self-Efficacy, Inventory of Parents and Peer Attachment and Kid at School questionnaires. Structural equation models (SEMs) were used to predict a latent variable of victimization with parents and peer attachment, emphasizing the mediating role of regulatory emotional self-efficacy, as comprised by a positive and a negative aspect. Results showed that peer attachment had an indirect negative effect, through perceived self-efficacy, in managing a positive effect in victimization, while father attachment had an indirect negative affect, through perceived self-efficacy, in managing a negative affect in victimization, and Mother attachment had no statistically significant indirect effect in victimization. This study suggests that the roles of parents and peers, and also between mothers and fathers, are different in relation to the perception of victimization of adolescents. Findings provide relevant information regarding implications for prevention and intervention in victimization.

Hungry for inclusion: Exposure to peer victimization and heightened social monitoring in adolescent girls

Belonging to a social group is one of the most important factors contributing to well-being. The Belonging Regulation model proposes that humans possess a social monitoring system (SMS) that evaluates social inclusion and monitors belonging needs. Here, we used a prospective longitudinal design to examine links between peer victimization experienced across 7 years and social monitoring at the behavioral and neural level in adolescent girls (n = 38, Mage = 15.43 years, SD = .33). Participants completed a social evaluation task during a functional magnetic resonance imaging (fMRI) scan. More severe peer victimization was associated with increased activation to in-group versus out-group peers in the amygdala, ventral striatum, fusiform gyrus, and temporoparietal junction. Moreover, participants who displayed increased activation in these regions reported lower social self esteem and higher levels of internalizing and externalizing symptoms. These results suggest that exposure to peer victimization across the school years is associated with heightened social monitoring at the neural level during adolescence, which has potential adverse implications for girls' adjustment and well-being.

Peer Victimization and Problem Behaviors: The Roles of Self-Esteem and Parental Attachment Among Chinese Adolescents

Guided by the social-ecological diathesis-stress model, this longitudinal study examined the roles of self-esteem, parental attachment, and gender on the association between peer victimization and problem behaviors among Chinese early adolescents. A total of 466 Chinese middle school students (M_age  = 12.8 years) completed measures of peer victimization, self-esteem, and paternal and maternal attachment twice (T1 and T2; 6-month interval). Their guardians also completed ratings on adolescents' problem behaviors at both T1 and T2. Results indicated that self-esteem mediated the association between peer victimization and problem behaviors. Paternal attachment, but not maternal attachment, moderated the mediating effect of self-esteem. Moreover, the moderating effect of maternal attachment on the association between peer victimization and self-esteem varied depending on adolescents' gender.

The Differential Victimization Associated With Depression and Anxiety in Cross-Cultural Perspective: A Meta-Analysis

Traditional bullying and cyberbullying have become serious worldwide issues. The meta-analysis in this article took a cross-cultural perspective to explore whether there were any differences between the effects of cyber victimization and traditional victimization on the presence of depression and anxiety in children and adolescents and to examine the effects of moderators in explaining these differences/similarities. Fifty-six empirical studies (generating 148 independent samples) were included with a total sample size of 214,819 participants. The results indicated that the effects of cyber victimization and the subtypes of traditional victimization on anxiety were significantly different, and there was a marginally significant difference for depression. The moderating effects of country of origin were found to be significant for depression, with the mean effect size in North America being significantly higher than in China and Europe, which suggested that culture was an important factor. The moderating effects of age were also found to be significant for the relationships between traditional victimization and depression, traditional victimization and anxiety, cyber victimization and depression, and cyber victimization and anxiety. In addition, the effect size for cyber victimization and depression has increased in more recent publication years.

Subtypes of peer victimization, depressive symptoms, and self-harm behaviors among children affected by parental HIV

OBJECTIVES

Peer victimization is a salient stressor contributing to self-harm behaviors in children. However, the psychological mechanisms underlying this process are not well understood. The aim of this study was to examine the role of depressive symptoms in the relationships between subtypes of peer victimization and self-harm behaviors among children affected by parental HIV using a prospective design.

METHODS

Participants in this study consisted of a subsample (N = 521, 6-12 years of age at baseline) of a larger research project on the psychological adjustment of children affected by parental HIV. Children self-reported subtypes of peer victimization including physical, verbal, and relational forms, depressive symptoms, and self-harm behaviors.

RESULTS

Structural equation models showed that verbal victimization, but not physical or relational victimization, was associated with increases in self-harm behaviors over a 24-month period (β = 0.18, p = .029). Moreover, the association between verbal victimization and self-harm behaviors was mediated by increases in depressive symptoms (indirect effect = 0.04, 95%CI [0.01, 0.08]), controlling for baseline self-harm behaviors, depressive symptoms, gender, AIDS orphan status, and age. In addition, such a mediation pathway was consistent across gender.

CONCLUSIONS

Depressive symptoms might be a psychological mechanism linking verbal victimization to self-harm behaviors among children affected by parental HIV. The findings highlight the importance of detection of depressive symptoms as a potential way to prevent self-harm behaviors among victimized children or those at high risk of experiencing peer victimization such as children affected by parental HIV.

Relational victimization and peer affiliate prosocial behaviors in African American adolescents: Moderating effects of gender and antisocial behavior

INTRODUCTION

Experiencing relational victimization (e.g., peer exclusion, untrue rumors) during adolescence can have negative social-emotional consequences, including increased antisocial behavior and substance use. The negative impact of relational victimization may be lessened by spending time with supportive, prosocial peers.

METHODS

This study examined the concurrent and predictive associations between relational victimization and peer affiliates' prosocial behaviors in 244 predominately African American adolescents (ages 13-14) living in U.S. urban neighborhoods. Questionnaires were collected every six months for two years. Overt victimization was controlled for in the analysis and the moderation of gender and antisocial behaviors were tested.

RESULTS

Peer affiliates' prosocial behavior was stable across the two years. Relational victimization was not associated with peers' prosocial behavior at baseline or across time. Gender did not moderate the association between relational victimization and peers' prosocial behavior. Moderating effects were found for antisocial behavior; relational victimization was positively associated with peer affiliates' prosocial behavior but only for adolescents who were low on antisocial behavior at baseline.

CONCLUSIONS

For African American youth, efforts to reduce relational aggression and increase peer support in prosocial activities prior to adolescence may be useful for preventing social-emotional problems.

Chronic peer victimization heightens neural sensitivity to risk taking

Although behavioral and experimental studies have shown links between victimization and antisocial behavior, the neural correlates explaining this link are relatively unknown. In the current study, we recruited adolescent girls from a longitudinal study that tracked youths' reports of peer victimization experiences annually from the second through eighth grades. Based on these reports, 46 adolescents were recruited: 25 chronically victimized and 21 nonvictimized. During a functional magnetic resonance imaging scan, participants completed a risk-taking task. Chronic peer victimization was associated with greater risk-taking behavior during the task and higher levels of self-reported antisocial behavior in everyday life. At the neural level, chronically victimized girls showed greater activation in regions involved in affective sensitivity, social cognition, and cognitive control, which significantly mediated victimization group differences in self-reported antisocial behavior.

The impact of extrafamilial victimization and poly-victimization on the psychological well-being of English young people

Childhood victimization impacts on the well-being of children and young people, particularly those experiencing an extreme amount of different types of victimization (i.e., poly-victims). However, limited attention has been given to the impact of different categories of extrafamilial victimization (experienced outside of the family), particularly in the UK. The intricacies of the significant detrimental impact poly-victimization has on victims are also poorly understood. In this study, 730 young people, aged 13 to 16 years (mean 13.8 years), from one county in the UK, were surveyed about their lifetime and past year experiences of extrafamilial victimization, the locations in which these occurred, and current trauma symptoms. The results showed that interpersonal forms of extrafamilial victimization (e.g., sexual victimization) were significant predictors of trauma, whilst more indirect forms of extrafamilial victimization (e.g., witnessing the victimization of others) were not. When extrafamilial poly-victimization and number of extrafamilial victim locations were accounted for within regression models, however, this impact was reduced. Poly-victimization within the past year was the strongest predictor of trauma symptoms. Number of victim locations did not significantly predict trauma symptoms above and beyond the impact of poly-victimization, although it was a contributory predictor. These findings suggest that a holistic exploration of a young person's extrafamilial victim experiences is needed in any clinical assessment or research into its psychological impact. Specifically, attention should be given to the experiencing of extreme levels of victimization (e.g., poly-victimization). Further longitudinal research is needed to understand why poly-victimization has the greatest impact on psychological well-being.

A Longitudinal Rejection Sensitivity Model of Depression and Aggression: Unique Roles of Anxiety, Anger, Blame, Withdrawal and Retribution

In this longitudinal study, attributional and social processes involved in symptoms of mental health problems (depressive symptoms and aggressive behavior) were identified by investigating anxious and angry rejection sensitivity (RS), causal attributions of self-blame and peer-blame, and responses to rejection threat of withdrawal and retribution. Young adolescents (N = 713, grades 5-7) completed questionnaires three times in their regular classrooms over 14 months. Participants who reported more self-blame for rejection were more likely to withdraw in response to rejection threat, and withdrawal and anxious RS were associated with increased depressive symptoms at T3 relative to T1. In contrast, adolescents higher in the angry form of RS and who reported more peer-blame for rejection were more likely to seek retribution, which in turn was associated with more overt/relational aggressive behavior at T3 relative to T1. Depressive symptom level measured at T1 also was associated with later RS and coping with withdrawal, and aggressive behavior at T1 was associated with later retribution. Sex of the participants did not moderate any longitudinal associations, and only one prospective path, from T1 depressive symptoms to T2 RS anxious, was moderated by age.

Longitudinal and Incremental Relation of Cybervictimization to Negative Self-Cognitions and Depressive Symptoms in Young Adolescents

Adolescents are among the most frequent users of social media websites, raising concern about the dangers of cyber bullying or cybervictimization (CV). A 12-month longitudinal study examined the unique, prospective relation of CV to the development of negative self-cognitions and depressive symptoms in a community sample of 827 children and young adolescents (ages 8-13; 55.1 % female) from the southeastern United States. Over and above conventional types of peer victimization, CV significantly predicted changes in self-referential negative cognitions, victimization-related cognitive reactions, and depressive symptoms, even after controlling for baseline levels of the dependent variables. Results also showed that CV was significantly less stable than other forms of victimization and tended to increase slightly with time. The study highlights the unique effects of CV and has implications for research and practice.

School Violence, Depressive Symptoms, and Help-seeking Behavior: A Gender-stratified Analysis of Biethnic Adolescents in South Korea

OBJECTIVES

In South Korea (hereafter Korea), the number of adolescent offspring of immigrants has rapidly increased since the early 1990s, mainly due to international marriage. This research sought to examine the association between the experience of school violence and mental health outcomes, and the role of help-seeking behaviors in the association, among biethnic adolescents in Korea.

METHODS

We analyzed cross-sectional data of 3627 biethnic adolescents in Korea from the 2012 National Survey of Multicultural Families. Based on the victim's help-seeking behavior, adolescents who experienced school violence were classified into three groups: 'seeking help' group; 'feeling nothing' group; 'not seeking help' group. Multivariate logistic regression was applied to examine the associations between the experience of school violence and depressive symptoms for males and females separately.

RESULTS

In the gender-stratified analysis, school violence was associated with depressive symptoms in the 'not seeking help' (odds ratio [OR], 7.05; 95% confidence interval [CI], 3.76 to 13.23) and the 'seeking help' group (OR, 2.77; 95% CI, 1.73 to 4.44) among male adolescents after adjusting for potential confounders, including the nationality of the immigrant parent and Korean language fluency. Similar associations were observed in the female groups. However, in the 'feeling nothing' group, the association was only significant for males (OR, 8.34; 95% CI, 2.82 to 24.69), but not females (OR, 0.77; 95% CI, 0.18 to 3.28).

CONCLUSIONS

This study suggests that experience of school violence is associated with depressive symptoms and that the role of victims' help-seeking behaviors in the association may differ by gender among biethnic adolescents in Korea.

Rumination about Social Stress Mediates the Association between Peer Victimization and Depressive Symptoms during Middle Childhood

Although prior research has established a link between exposure to peer victimization and depressive symptoms, relatively little is known about the processes underlying this association. This study examined whether maladaptive responses to a novel social stressor - specifically, lower levels of problem solving or higher levels of rumination - mediate this association. Data were gathered from 130 children (64 boys, 66 girls; M age = 9.46, SD = .33) who participated in a laboratory social stressor task with an unfamiliar peer. Results indicated that prior exposure to peer victimization in the school context was associated with ruminative responses to the novel stressor, which mediated the association between victimization and depressive symptoms. These results indicate that ruminative responses to social stress outside of the victimization context may serve as one process explaining the association between victimization and heightened depressive symptoms.

Interpersonal stressors in the schoolyard and depressive symptoms among Chinese adolescents: The mediating roles of rumination and co-rumination

Stressors have been identified as significant vulnerability factors in the development of adolescents’ depression. The present study focused on the relationship between depressive symptoms and two types of interpersonal stressors in the schoolyard, namely teacher-student interaction stressors (TSIS) and peer interaction stressors (PIS). More importantly, rumination and co-rumination were examined as two possible mechanisms to account for these relationships. A convenience sample of 570 Chinese adolescents aged from 12- to 19-years-old participated in this research. Results indicated that TSIS and PIS were significantly related to participants’ depressive symptoms. Furthermore, rumination partially mediated the relationship between PIS and depressive symptoms. Co-rumination was a partial mediator between both types of interpersonal stressors and depressive symptoms. Hence, rumination and co-rumination might serve as two mechanisms linking interpersonal stressors in the schoolyard and depressive mood in adolescence. The findings are discussed in the light of related literature and potential implications for school practitioners.

A Longitudinal Rejection Sensitivity Model of Depression and Aggression: Unique Roles of Anxiety, Anger, Blame, Withdrawal and Retribution

In this longitudinal study, attributional and social processes involved in symptoms of mental health problems (depressive symptoms and aggressive behavior) were identified by investigating anxious and angry rejection sensitivity (RS), causal attributions of self-blame and peer-blame, and responses to rejection threat of withdrawal and retribution. Young adolescents (N = 713, grades 5-7) completed questionnaires three times in their regular classrooms over 14 months. Participants who reported more self-blame for rejection were more likely to withdraw in response to rejection threat, and withdrawal and anxious RS were associated with increased depressive symptoms at T3 relative to T1. In contrast, adolescents higher in the angry form of RS and who reported more peer-blame for rejection were more likely to seek retribution, which in turn was associated with more overt/relational aggressive behavior at T3 relative to T1. Depressive symptom level measured at T1 also was associated with later RS and coping with withdrawal, and aggressive behavior at T1 was associated with later retribution. Sex of the participants did not moderate any longitudinal associations, and only one prospective path, from T1 depressive symptoms to T2 RS anxious, was moderated by age.

Latent trajectories of adolescent antisocial behavior: Serotonin transporter linked polymorphic region (5-HTTLPR) genotype influences sensitivity to perceived parental support

Although prevailing theories of antisocial behavior (ASB) emphasize distinct developmental trajectories, few studies have explored gene–environment interplay underlying membership in empirically derived trajectories. To improve knowledge about the development of overt (e.g., aggression) and covert (e.g., delinquency) ASB, we tested the association of the 44-base pair promoter polymorphism in the serotonin transporter linked polymorphic region gene (5-HTTLPR), perceived parental support (e.g., closeness and warmth), and their interaction with ASB trajectories derived using latent class growth analysis in 2,558 adolescents followed prospectively into adulthood from the National Longitudinal Study of Adolescent Health. Three distinct trajectories emerged for overt (low desisting, adolescent peak, and late onset) and covert ASB (high stable, low stable, and nonoffending). Controlling for sex, parental support inversely predicted membership in the adolescent-peak overt ASB trajectory (vs. low desisting), but was unrelated to class membership for covert ASB. Furthermore, the 5-HTTLPR genotype significantly moderated the association of parental support on overt ASB trajectory membership. It is interesting that the pattern of Gene × Environment interaction differed by trajectory class: whereas short allele carriers were more sensitive to parental support in predicting the late-onset trajectory, the long/long genotype functioned as a potential “plasticity genotype” for the adolescent-peak trajectory group. We discuss these preliminary findings in the context of the differential susceptibility hypothesis and discuss the need for future studies to integrate gene–environment interplay and prospective longitudinal designs.

Social Information Processing Mechanisms and Victimization: A Literature Review

The aim of the current literature review, which is based on 64 empirical studies, was to assess to what extent mechanisms of the Social Information Processing (SIP) model of Crick and Dodge (1994) are related to victimization. The reviewed studies have provided support for the relation between victimization and several social information processing mechanisms, especially the interpretation of cues and self-efficacy (as part of the response decision). The relationship between victimization and other mechanisms, such as the response generation, was only studied in a few articles. Until now research has often focused on just one step of the model, instead of attempting to measure the associations between multiple mechanisms and victimization in multivariate analyses. Such analyses would be interesting to gain more insight into the SIP model and its relationship with victimization. The few available longitudinal studies show that mechanisms both predict victimization (internal locus of control, negative self-evaluations and less assertive response selection) and are predicted by victimization (hostile attribution of intent and negative evaluations of others). Associations between victimization and SIP mechanisms vary across different types and severity of victimization (stronger in personal and severe victimization), and different populations (stronger among young victims). Practice could focus on these stronger associations and the interpretation of cues. More research is needed however, to investigate whether intervention programs that address SIP mechanisms are suitable for victimization and all relevant populations.

Multifinality of peer victimization: maladjustment patterns and transitions from early to mid-adolescence

Peer victimization is a common and pervasive experience in childhood and adolescence and is associated with various maladjustment symptoms, including internalizing, externalizing, and somatic problems. This variety suggests that peer victimization is multifinal where exposure to the same risk leads to different outcomes. However, very little is known about the relative likelihood of each form of maladjustment. We used a latent profile approach to capture multiple possible outcomes and examined prediction by peer victimization. We also examined the role of peer victimization with regard to stability and change in maladjustment. Maladjustment symptoms and peer victimization were assessed from the participants of the large cohort study TRacking Adolescents' Individual Lives Survey in early and mid-adolescence. Latent profile and latent transition analyses were conducted to examine associations between victimization and maladjustment profile and to test the role of victimization in maladjustment profile transitions. Four maladjustment profiles were identified for early adolescence (Low, Internalizing, Externalizing, Comorbid) and three profiles (Low, Internalizing, Externalizing) were identified for mid-adolescence. Internalizing problems were more likely in victimized adolescents than low symptom levels or externalizing problems. Victimized adolescents were at greater risk to develop internalizing problems between early and mid-adolescence than non-victimized adolescents. Peer victimization is multifinal mostly when outcomes are examined separately. If multiple outcomes are tested simultaneously, internalizing problems seem to be the most likely outcome.

Peer victimization in middle childhood impedes adaptive responses to stress: a pathway to depressive symptoms

Although associations between peer victimization in childhood and later psychopathology are well documented, surprisingly little research directly examines pathways accounting for these enduring effects. The present study addresses this issue by examining whether maladaptive responses to peer aggression (less effortful engagement coping and more involuntary responses) mediate associations between peer victimization and later depressive symptoms. Data were collected on 636 children (338 girls, 298 boys; M = 8.94 years, SD = .37) for three consecutive years beginning in 3rd grade. Findings supported the proposition that peer victimization predicts lower levels of effortful engagement coping and higher levels of involuntary engagement and disengagement responses to stress. Moreover, these responses to stress helped to explain the link between 3rd-grade peer victimization and 5th-grade depressive symptoms. No sex differences in these linkages emerged. These findings build on prior theory and research by providing a more nuanced understanding of how and why peer victimization serves as an early risk factor for depressive symptoms.

Contributions of Socialization of Coping to Physiological Responses to Stress

The messages mothers communicate to their children about coping may play an important role in children's emotional development by shaping children's responses to stress. Building on prior research demonstrating associations between maternal socialization of coping (SOC) and children's self-reported coping and emotional functioning (Abaied & Rudolph, 2010; 2011), we examined the contribution of SOC to children's physiological responses to stress. Mothers completed a measure of SOC with peer victimization. Children (N = 118; M age = 9.46 years, SD = 0.33) completed a measure of peer victimization and participated in a laboratory social challenge task. Saliva samples were collected prior to and following the task and were assayed for alpha-amylase (sAA), a marker of autonomic nervous system (ANS) activation. Hierarchical linear modeling analyses revealed that SOC contributed to sAA reactivity. Peer victimization predicted greater sAA reactivity when mothers made few engagement suggestions (orienting toward stress and associated emotions and cognitions) but not when mothers made many engagement suggestions. Mothers' distress responses predicted greater sAA reactivity. These findings provide novel evidence that the messages parents communicate about coping have implications for children's physiological reactivity to stress during middle childhood.

Early childhood precursors and adolescent sequelae of grade school peer rejection and victimization

This study examined the early childhood precursors and adolescent outcomes associated with grade school peer rejection and victimization among children oversampled for aggressive-disruptive behaviors. A central goal was to better understand the common and unique developmental correlates associated with these two types of peer adversity. There were 754 participants (46% African American, 50% European American, 4% other; 58% male; average age=5.65 at kindergarten entry) followed into seventh grade. Six waves of data were included in structural models focused on three developmental periods. Parents and teachers rated aggressive behavior, emotion dysregulation, and internalizing problems in kindergarten and Grade 1 (Waves 1-2); peer sociometric nominations tracked "least liked" and victimization in Grades 2, 3, and 4 (Waves 3-5); and youth reported on social problems, depressed mood, school adjustment difficulties, and delinquent activities in early adolescence (Grade 7, Wave 6). Structural models revealed that early aggression and emotion dysregulation (but not internalizing behavior) made unique contributions to grade school peer rejection; only emotion dysregulation made unique contributions to grade school victimization. Early internalizing problems and grade school victimization uniquely predicted adolescent social problems and depressed mood. Early aggression and grade school peer rejection uniquely predicted adolescent school adjustment difficulties and delinquent activities. Aggression and emotion dysregulation at school entry increased risk for peer rejection and victimization, and these two types of peer adversity had distinct as well as shared risk and adjustment correlates. Results suggest that the emotional functioning and peer experiences of aggressive-disruptive children deserve further attention in developmental and clinical research.
