Peer victimization, depressive symptoms, and high salivary cortisol predict poorer memory in children

The predictive relations of peer victimization, depressive symptoms, and salivary cortisol on memory in 168 children aged 12 at Time 1 (T1) were examined using a longitudinal design in which data were collected on four occasions over a 2-year period. Results indicated that: (1) peer victimization, depressive symptoms, and evening cortisol were stable over time, (2) peer victimization and elevated symptoms of depression were concurrently linked at each time, (3) T1 peer victimization predicted elevated symptoms of depression at T2 which in turn predicted lower cortisol levels at T3, and (4) controlling for earlier associations, T3 peer victimization, depressive symptoms, and higher morning and evening cortisol levels uniquely predicted memory deficits at T4. The links between elevated cortisol, symptoms of depression, and poor memory are consistent with published research on depressed adults and extend the findings to children exposed to peer victimization. These findings highlight that peer abuse is harmful and may impact children's long-term mental health and memory functioning.     

The Role of Emotion Dysregulation in the Links Between Sibling Victimization and Internalizing Symptoms in Middle Childhood

Despite sibling victimization being a relatively common occurrence, there is a dearth of research examining the outcomes associated with this interpersonal stressor, including internalizing symptoms. The current study sought to advance the literature by longitudinally examining the links from sibling victimization to depression and anxiety symptoms while also considering peer victimization in a sample of elementary school-age youth (51.8% boys, M age?=?8.72) who were initially in 3rd and 4th grade. Further, emotion dysregulation was examined as a mediator of these associations. Youth provided self-reports at three separate time points approximately 6 months apart. Path analysis models indicated that emotion dysregulation mediated the association between sibling, but not peer, victimization and increased depression symptoms. However, neither sibling nor peer victimization were associated with anxiety symptoms over time. Results suggest the importance of attending to sibling victimization for the prevention of emotion dysregulation difficulties and ultimately early symptoms of depression. Youth assessments need to include questions about both sibling and peer victimization, and sibling victimization needs to be included as a target of prevention and intervention for subsequent internalizing difficulties.

     

Relation of Depression and Anxiety to Self‐ and Peer‐Reported Relational Aggression

The primary purpose of this multimethod and multimeasure study was to identify how the peer relationships of Australian adolescents (ages 9–15 years; N = 335) at school, including relational aggression and victimization, correlated with their symptoms of depression and anxiety. Moreover, relational aggression and victimization were measured via both self‐ and peer report, and discrepancies between reports were considered as correlates of symptoms and peer relationship status. Adolescents who reported more symptoms of depression and anxiety also self‐reported more relational victimization and reported their peers as less trustworthy. Adolescents who overreported their own relational victimization and aggression compared with peer report had more symptoms compared with those who agreed with their peers or underreported their aggression and victimization. Adolescents who underreported their own aggression were not only more socially prominent but were also more disliked by their peers. When considered independent of self‐reports, no measure of peer‐reported peer status, aggression, or victimization was associated with depressive symptoms; but adolescents reported as more accepted by their peers had fewer anxiety symptoms. Longitudinal research should be conducted to examine adolescents' increasing socioemotional problems as correlates of discrepancies between self‐ and peer reports of relational aggression and victimization.

Overt and relational aggression in adolescents: social-psychological adjustment of aggressors and victims.

Examined the relative and combined associations among relational and overt forms of aggression and victimization and adolescents' concurrent depression symptoms, loneliness, self-esteem, and externalizing behavior. An ethnically diverse sample of 566 adolescents (55% girls) in Grades 9 to 12 participated. Results replicated prior work on relational aggression and victimization as distinct forms of peer behavior that are uniquely associated with concurrent social-psychological adjustment. Victimization was associated most closely with internalizing symptoms, and peer aggression was related to symptoms of disruptive behavior disorder. Findings also supported the hypothesis that victims of multiple forms of aggression are at greater risk for adjustment difficulties than victims of one or no form of aggression. Social support from close friends appeared to buffer the effects of victimization on adjustment.     

Sex differences in the personal costs and benefits of relational and physical aggression in high school

While recent research using peer ratings demonstrates positive relations between youth's reputations for aggression and popularity, it is not clear whether aggressive youth themselves make these links. Using youth's self‐reports, this study assessed the associations of relational and physical aggression with indicators of both personal gains in peer relations (perceived popularity and receipt of prosocial attention) and personal costs in terms of retaliation or depressive responses (peer victimization and depressive symptoms) in a large sample (n=455) of eighth‐ to tenth‐grade students. Regression analyses reveal that more relationally aggressive youth report more prosocial attention but also more relational (but not physical) victimization. In contrast, more physically aggressive youth report more depressive symptoms and physical (but not relational) victimization. Findings suggest that some costs of aggression (victimization) are higher for boys while others (depressive symptoms) are greater for girls. Group differences were also found for aggressive, victimized, and aggressive/victimized youth compared to the typical low aggressive/low victimized youth. These data suggest that the costs of relational and physical aggression may outweigh benefits except for aggressive non‐victimized boys. Aggr. Behav. 32:409–419, 2006. © 2006 Wiley‐Liss, Inc.     

青少年早期同伴拒绝、同伴侵害与抑郁的关系：交叉滞后分析

采用间隔1年的追踪设计,使用结构方程建模对1068名青少年早期个体的同伴拒绝、同伴侵害与抑郁间的关系进行交叉滞后分析。结果发现,（1）在不同时间点上,同伴拒绝、同伴侵害和青少年抑郁之间存在显著正相关;（2）先前的抑郁水平对随后个体遭受的身体侵害和关系侵害均有显著预测作用,而先前的同伴侵害不能显著预测随后青少年的抑郁水平。抑郁对同伴拒绝、以及同伴拒绝对抑郁的预测作用均不显著。（3）同伴拒绝、同伴侵害与抑郁间的关系具有跨性别的一致性。这表明,青少年早期同伴侵害和抑郁间存在单向预测关系,抑郁导致同伴侵害。     

Do extraversion and neuroticism moderate the association between bullying victimization and internalizing symptoms? A three-wave longitudinal study

The current study examined the moderating roles of neuroticism and extraversion in victims of bullying. According to a stress-diathesis model, we hypothesized that adolescents with high levels of neuroticism and low levels of extraversion would react to victimization with increased symptoms of depression and social anxiety. A sample of 1440 adolescents (648 girls and 792 boys; ages between 13- and 17-years-old) completed measures of extraversion and neuroticism at time 1, as well as measures of bullying victimization, depressive symptoms and social anxiety symptoms at time 1, time 2, and time 3 (in intervals of six months). The results of multilevel analyses for longitudinal data indicated that there was a weak association between bullying victimization and social anxiety symptoms for the adolescents who scored high on extraversion. In addition, the adolescents with high levels of extraversion presented a greater reduction in depressive symptoms over time than adolescents with low levels. Although neuroticism predicted both depression and social anxiety, no significant interactions were evident between neuroticism and bullying victimization. Regarding gender differences, the association between bullying victimization and social anxiety was stronger for boys than for girls, whereas the association between neuroticism and depression was stronger for girls.     

Bidirectional Associations between Peer Victimization and Functions of Aggression in Middle Childhood: Further Evaluation across Informants and Academic Years

The current 3-wave study examined bidirectional associations between peer victimization and functions of aggression across informants over a 1-year period in middle childhood, with attention to potential gender differences. Participants included 198 children (51% girls) in the third and fourth grades and their homeroom teachers. Peer victimization was assessed using both child- and teacher-reports, and teachers provided ratings of reactive and proactive aggression. Cross-classified multilevel cross-lagged models indicated that child-reports, but not teacher-reports, of peer victimization predicted higher levels of reactive aggression within and across academic years. Further, reactive aggression predicted subsequent increases in child- and teacher-reports of peer victimization across each wave of data. Several gender differences, particularly in the crossed paths between proactive aggression and peer victimization, also emerged. Whereas peer victimization was found to partially account for the stability of reactive aggression over time, reactive aggression did not account for the stability of peer victimization. Taken together with previous research, the current findings suggest that child-reports of peer victimization may help identify youth who are risk for exhibiting increased reactive aggression over time. Further, they highlight the need to target reactively aggressive behavior for the prevention of peer victimization in middle childhood.     

Peer victimization and social anxiety in adolescence: a prospective study

This study reports a one‐year prospective investigation of the relations between overt and relational victimization and social anxiety and phobia in a sample of adolescents. The Social Experience Questionnaire—Self Report Form (SEQ‐S), Social Anxiety Scale for Adolescents (SAS‐A), and Social Phobia and Anxiety Inventory for Children (SPAI‐C) were administered to 144 ninth grade adolescents. A follow‐up assessment with the SEQ‐S, SAS‐A, and SPAI‐C was conducted one year later. Results indicated that relational victimization predicted symptoms of social phobia but not general social anxiety and avoidance one year later. Overt victimization was not a significant predictor of social anxiety and phobia one year later. Social anxiety and phobia did not predict peer victimization one year later. However, increases in social anxiety and social phobia symptoms (for boys) over time were positively associated with increases in relational victimization over time. Implications of these findings for peer victimization and social anxiety in the development of social phobia and negative peer experiences are discussed. Aggr.

Transactional Associations Between Youths’ Responses to Peer Stress and Depression: The Moderating Roles of Sex and Stress Exposure

This study examined transactional associations between responses to peer stress and depression in youth. Specifically, it tested the hypotheses that (a) depression would predict fewer effortful responses and more involuntary, dysregulated responses to peer stress over time; and (b) fewer adaptive and more maladaptive responses would predict subsequent depression. Youth (M age = 12.41; SD = 1.19; 86 girls, 81 boys) and their maternal caregivers completed semi-structured interviews and questionnaires at three annual waves. Multi-group comparison path analyses were conducted to examine sex and stress-level differences in the proposed reciprocal-influence model. In girls and in youth exposed to high levels of peer stress, maladaptive stress responses predicted more depressive symptoms and adaptive stress responses predicted fewer depressive symptoms at each wave. These findings suggest the utility of preventive interventions for depression designed to enhance the quality of girls’ stress responses. In boys, depression predicted less adaptive and more maladaptive stress responses, but only at the second wave. These findings suggest that interventions designed to reduce boys’ depressive symptoms may help them develop more adaptive stress responses.     

Change Pathways in Indigenous and Nonindigenous Youth Suicide

Multivariate dynamic relationships among suicide attempts, anxiety and/or depressive symptoms, hope, and help‐seeking were examined across time in Native Hawaiian and non‐Hawaiian adolescents, using data from a 5‐year longitudinal cohort study (N = 7,317). The rate of suicide attempts decreased over time, but this reduction was significantly less among Native Hawaiian youth than their non‐Hawaiian peers. There were also significant differences between groups in hope and help‐seeking, with Native Hawaiian youth increasing help‐seeking and decreasing hope to a greater degree. Youth‐centered, cultural approaches to suicide prevention are essential in enhancing well‐being in indigenous communities.     

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.

Behavioral Couples Treatment for Substance Use Disorder: Secondary Effects on the Reduction of Youth Internalizing Symptoms

This study examined the secondary effects of Behavioral Couples Treatment (BCT) for parents with substance use disorder on youth reports of internalizing symptoms (i.e., depressive and anxiety symptoms). Participants were 59 triads (father, mothers, and youth; 32 girls, 27 boys) in which one or both parents met criteria for drug or alcohol use disorder (or both). Mothers, fathers, and youth completed pretreatment, post-intervention, and 6-month post-intervention follow-up assessments. Two piecewise latent growth models examined whether number of sessions attended was associated with parents’ relationship satisfaction or its growth over time, and in turn if parents’ relationship satisfaction was uniquely associated with youth depressive/anxiety symptoms or their growth over time. A significant indirect effect at post-intervention revealed the number of sessions attended contributed to decreases in youth depressive symptoms via increases in mothers’ and fathers’ relationship satisfaction. Mothers’ relationship satisfaction uniquely mediated the relationship between number of sessions attended and youth depressive symptoms at post-intervention. With regards to fathers, there was a non-significant trend such that increases in sessions attended was associated with decreases in youth depressive symptoms post- intervention via increasing relationship satisfaction among fathers. Findings suggest that BCT may have protective secondary effects in reducing youth reports of depressive symptoms among couples in which one or both parents have substance use disorder.     

A Population Study of Victimization, Relationships, and Well-Being in Middle Childhood

The paper presents a population-based study on the association of victimization and peer and adult relationships with children’s life satisfaction, self-esteem, anxiety, and depressive symptoms. The study extends previous research by examining 2-, 3-, and 4-way higher-order interaction effects (moderation hypotheses) of adults and peer relationships, victimization, and gender on positive and negative aspects of children’s well-being. The study draws from a representative population-level sample of 2,792 4th graders (M _age = 9.70 years; 48.2 % girls). Data were obtained via student self-report survey on the Middle Years Development Instrument (MDI). Given the nested data (children within classrooms), we employed multi-level regression analyses. Positive relationships with adults and peers were most strongly associated with life satisfaction and self-esteem, whereas victimization was most strongly associated with depressive symptoms and anxiety. No significant 2- or 3-way interactions were identified. The 4-way interaction of gender, adult connectedness, peer connectedness, and victimization was significant for three outcomes; that is, victimization was particularly strongly associated with low life satisfaction, low self-esteem, and high depressive symptoms for girls with low self-reports of peer and adult connectedness. The findings have implications for promoting children’s well-being in school and community contexts, corroborating interventions that foster relationship-building skills and simultaneously reduce victimization.     

Online racial discrimination and the protective function of ethnic identity and self-esteem for African American adolescents

A growing body of literature has shown that being victimized online is associated with poor mental health. Little is known about the factors that protect youth from the negative outcomes that may result from these victimization experiences, particularly those related to race. Using a risk and resilience framework, this study examined the protective function of ethnic identity and self-esteem among African Americans who experience online racial discrimination. For the sample of 125 adolescents, hierarchical regression results revealed that higher levels of ethnic identity and self-esteem significantly moderated the negative impact of online racial discrimination on anxiety levels. These findings show that ethnic identity and self-esteem can buffer the negative mental health outcomes associated with online racial discrimination, at least with respect to adolescents' anxiety. Findings from the current study have significant implications for adolescent adjustment given the increased time youth spend doing online activities.     

Parental Behaviors During Family Interactions Predict Changes in Depression and Anxiety Symptoms During Adolescence

This study investigated the prospective, longitudinal relations between parental behaviors observed during parent-adolescent interactions, and the development of depression and anxiety symptoms in a community-based sample of 194 adolescents. Positive and negative parental behaviors were examined, with negative behaviors operationalized to distinguish between observed parental expressions of aggression and dysphoria. Results showed that higher levels of parental aggression prospectively predicted higher levels of both depression and anxiety symptoms in adolescents over two-and-a-half years, whereas higher levels of positive parental behaviors prospectively predicted lower levels of depression symptoms only. Parental dysphoric behavior was not related to changes in either symptom dimension. These results suggest that patterns of parental behaviors may be differentially associated with depressive versus anxious outcomes in adolescents, and highlight the potential role for family-focused prevention or treatment interventions aimed at reducing an escalation of depression and anxiety symptoms in adolescence.     

Trajectories of perceived adult and peer discrimination among Black, Latino, and Asian American adolescents: patterns and psychological correlates

This article presents results from a 3-year longitudinal study of the growth patterns and correlates of perceived discrimination by adults and by peers among Black, Latino, and Asian American high school students. Results revealed a linear increase over time in levels of perceived discrimination by adults, whereas perceptions of discrimination by peers remained stable over time. Asian American and non-Puerto Rican Latino adolescents (primarily Dominican) reported higher levels of peer and/or adult discrimination than did Puerto Rican youth, whereas Black adolescents reported a steeper increase over time in levels of perceived discrimination by peers and by adults than did Puerto Rican adolescents. Peer and adult discrimination was significantly associated with decreased self-esteem and increased depressive symptoms over time. Ethnic identity and ethnicity were found to moderate the relationships between perceived discrimination and changes in psychological well-being over time. Results underscore the need to include perceptions of discrimination when studying the development and well-being of ethnic minority adolescents.     

DRD2基因TaqIA多态性与同伴侵害对青少年早期抑郁的交互作用

本研究运用问卷法与DNA分型技术,对1063名青少年(初次测评年龄为12.32±0.47岁,50.3%女生)进行间隔2年的追踪调查,考察DRD2基因TaqIA多态性与同伴身体侵害和关系侵害对青少年早期抑郁的交互作用及其性别差异。结果发现,TaqIA多态性与身体侵害、关系侵害均对男青少年抑郁存在显著的交互作用。在携带A2A2基因型的男生中,身体侵害和关系侵害可以显著正向预测其抑郁水平,而在携带A1等位基因的男生中,同伴侵害对抑郁无预测作用。此外,TaqIA多态性与身体侵害、关系侵害对女生抑郁均无显著交互作用。研究结果提示,同伴侵害是一种重要的候选环境指标,与TaqIA多态性交互影响青少年早期抑郁,并且性别在这一基因×环境交互作用中起到重要的调节效应。
