Subjective, Autonomic, and Endocrine Reactivity during Social Stress in Children with Social Phobia

Reports of exaggerated anxiety and physiological hyperreactivity to social-evaluative situations are characteristic of childhood social phobia (SP). However, laboratory research on subjective, autonomic and endocrine functioning in childhood SP is scarce, inconsistent and limited by small sample sizes, limited breadth of measurements, and the use of non-standardized stressor tasks. We exposed 8–12-year-old children with DSM-IV SP (n = 41) and matched healthy control children (HC; n = 40) to the Trier Social Stress Test for Children (TSST-C) while measuring subjective anxiety, heart rate (HR) and salivary alpha-amylase (sAA) as well as salivary cortisol. The SP children showed heightened reactivity to the TSST-C on subjective anxiety compared to the HC children but not a heightened reactivity in HR, sAA or cortisol. However, the SP children showed chronically elevated HR levels throughout the whole laboratory session. Whereas subjective anxiety seems to respond specifically to social-evaluative stress in childhood SP, HR levels may be chronically elevated suggesting a more generalized autonomic hyperreactivity.     

Hypothalamic Pituitary Adrenal Axis Functioning in Reactive and Proactive Aggression in Children

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to elicit fear (N = 33) or frustration (N = 32), or a validity check condition (N = 8). This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples for cortisol analysis were collected including 12 post-stress samples at 5-min intervals. Reactive and proactive aggression levels were assessed via the teacher-completed Aggression Behavior Teacher Checklist (Dodge and Coie, J Pers Soc Psychol, 53(6), 1146–1158, 1987). Reactive aggression significantly predicted total and peak post-stress cortisol regardless of stress modality. Proactive aggression was not a predictor of any cortisol index. Examination of pure reactive, proactive, combined, or non-aggressive children indicated that reactive aggressive children had higher cortisol reactivity than proactive and non-aggressive children. Our data suggest that while an overactive HPA-axis response to stress is associated with reactive aggression, stress induced HPA-axis variability does not seem to be related to proactive aggression.     

Associations between Maternal Physical Discipline and Peer Victimization among Hong Kong Chinese Children: The Moderating Role of Child Aggression

This study examines the relation between maternal physical discipline and victimization by peers, as moderated by child aggression. The sample consisted of 211 Hong Kong Chinese children (98 boys, 113 girls; average age of 11.9). Physical discipline was assessed with a questionnaire completed by mothers, and victimization by peers and aggression were measured using a peer nomination inventory. Latent variable models revealed a moderately strong link between children’s experiences with maternal physical discipline and peer victimization, but this effect held only for children who were also high on aggression. These results highlight the interplay between harsh home environments and child aggression and their contributions to the child’s adjustment in the peer group.     

Friendship as Protection from Peer Victimization for Girls with and without ADHD

The goal of this study was to examine the ability of friendship to moderate the association between behavioral risk and peer victimization for girls with attention-deficit/hyperactivity disorder (ADHD; n = 140) and comparison girls (n = 88) in a 5-week naturalistic summer camp setting. Participants were an ethnically and socioeconomically diverse group of girls ages 6–12. Parents and teachers reported on pre-summer internalizing behavior, externalizing behavior, and social competence. Participants reported on friendships and peer victimization through a peer report measure at the summer camps; friendship was scored via mutual nominations. Pre-summer externalizing behavior, internalizing behavior, and low social competence predicted peer victimization at the summer camps. Friendship moderated the association between behavioral risk and victimization for the entire sample, such that the presence of at least one friend reduced the risk of victimization. Additional analyses suggested that girls with ADHD were no more or less protected by the presence of a friendship than were comparison girls. Finally, preliminary analyses suggested that girls having only friends with ADHD were not significantly less protected than girls with at least one comparison friend. Future directions and implications for intervention are discussed.     

Coping with Social Stress: Implications for Psychopathology in Young Adolescent Girls

This study investigated the impact of social stress on symptoms of psychopathology at the entry into adolescence (111 girls, Mage = 11.84, SD = 0.77). We examined whether peer stress and pubertal timing were associated with internalizing distress and aggression, and whether responses to stress and cortisol reactivity mediated or moderated these associations. Cortisol samples were collected from saliva samples during in-home visits, and the YSR was used to assess psychopathology. Interestingly, pubertal timing demonstrated a trend association with cortisol. Responses to stress mediated the association between social stress and symptoms of internalizing distress and aggression. Specifically, early maturers and girls with higher levels of peer stress exhibited more problematic responses to stress, in turn demonstrating higher levels of internalizing distress and aggression. Significant moderation effects also emerged. For example, early maturers who experienced higher levels of emotional/cognitive numbing in response to peer stress were at greater risk for aggression. Findings identify coping strategies that may be used in evidence-based programming to help girls transition more successfully into adolescence will be discussed.

The Effect of Induced Mood on Children’s Social Information Processing: Goal Clarification and Response Decision

We investigated whether induced mood influenced the social information processing steps of goal clarification and response decision in 480 1st–3rd graders, and in more selected groups of low accepted-aggressive (n = 39), average accepted-nonaggressive (n = 103), and high accepted-nonaggressive children (n = 68). Children participated in two sessions; in the first session peer assessments were administered. In the second session children were randomly assigned to receive either a happy, angry, or neutral mood induction prior to participating in a social cognitive interview assessing goals, outcome expectancies, and self efficacy for competent, hostile, and passive responses in the context of ambiguous provocations. Results revealed that an angry mood increased focus on instrumental goals. Low accepted-aggressive children were more susceptible to the effects of mood than were high accepted- and average-nonaggressive children. In addition, children’s predominant goal orientation was related to children’s response decisions; children with predominantly instrumental goals evaluated nonhostile responses to provocation more negatively and had higher self efficacy for hostile responses. Implications and future research directions are discussed.     

The Latent Structure of Youth Responses to Peer Provocation

This study examined whether the three categories often applied to children’s behavior—aggressive, avoidant, and assertive—actually capture the structure of a naturalistic sample of youth behavior coded at a more micro level. A sample of lower-income youth (N = 392; M age = 12.69, SD = 0.95) completed a new multiple-choice measure asking them to select responses to scenarios depicting physical, verbal, and relational provocation by a peer. Youth responses to the vignettes showed the expected associations with self-reported aggression and regulation of anger, providing preliminary evidence for the convergent validity of the measure. Factor analysis confirmed that responses loaded on three factors: aggression, avoidance, and assertion. Model fit was adequate (RMSEA = .028) and cross-validated in a second sample (RMSEA = .039). Several types of responses loaded on two factors suggesting that some strategies that youth use to manage provocation are not “pure” examples of these broadband categories. Implications for conceptualization and measurement of youth social behavior are discussed.     

Positive Illusions of Social Competence in Girls with and Without ADHD

We compared social self-competence ratings in 9–12 year old girls with (n = 42) versus without (n = 40) ADHD, relative to ratings of the girls’ social competence made by mothers, teachers, and blind raters during a social laboratory task. Relative to scores from mothers, teachers, and the lab-task, girls with ADHD over-estimated their competence significantly more than control girls. Over-estimates were greater for girls with ADHD who also had heightened oppositional-defiant symptoms, or lower depressive symptoms. Over-estimates were positively related to a socially desirable reporting bias for girls with ADHD, but not for control girls, suggesting that girls with ADHD attempt to present themselves in an unduly positive, self-protective light. For girls with ADHD, over-estimates also were positively related to maladjustment and negatively related to adjustment. However, for girls without ADHD, over-estimates were positively related to adjustment. Overall, over-estimates of competence function differently in girls with and without ADHD.     

Biased Self-Perceptions,Peer Rejection,and Aggression in Children

This study examined whether children’s biased self-perceptions of peer acceptance are associated in a linear or curvilinear fashion with aggression, whether associations are moderated by peer rejection status, and whether associations apply uniquely to reactive aggression. Children in the 4th through 7th grades completed a self-report measure on their social functioning (SPPC; Harter 1982), and teachers reported on children’s social functioning and aggression. Self-perceptual bias was operationalized as the standardized residual difference between children’s self-perceptions and their teachers’ perceptions of their peer acceptance. Rejected status moderated associations between biased self-perceptions and reactive aggression. Among non-rejected children, biased perceptions were not significantly associated with reactive aggression. In contrast, among peer-rejected children, reactive aggression was elevated in those who greatly underestimated as well as in those who even modestly overestimated their peer acceptance. This pattern was observed whether or not proactive aggression was statistically controlled. In contrast, biased self-perceptions were not associated with proactive aggression for rejected or nonrejected children. Implications are discussed with regard to future research and potential interventions for aggressive children.     

Longitudinal Pathways Between Political Violence and Child Adjustment: The Role of Emotional Security about the Community in Northern Ireland

Links between political violence and children’s adjustment problems are well-documented. However, the mechanisms by which political tension and sectarian violence relate to children’s well-being and development are little understood. This study longitudinally examined children’s emotional security about community violence as a possible regulatory process in relations between community discord and children’s adjustment problems. Families were selected from 18 working class neighborhoods in Belfast, Northern Ireland. Participants (695 mothers and children, M = 12.17, SD = 1.82) were interviewed in their homes over three consecutive years. Findings supported the notion that politically-motivated community violence has distinctive effects on children’s externalizing and internalizing problems through the mechanism of increasing children’s emotional insecurity about community. Implications are considered for understanding relations between political violence and child adjustment from a social ecological perspective.     

Middle school students' perceptions of school climate,bullying prevalence,and social support and coping

The aim of this exploratory study was to examine middle school students’ (N = 88) perceptions of bullying, school climate and social support and coping. Data were collected using online surveys (n = 80) and face-to-face interviews (n = 8). Quantitative analyses revealed that prevalence of teasing, victimization, and bullying experiences significantly predicted perceptions of school climate. Qualitative findings provided further insight into student perceptions of bullying indicating several overlapping themes, when examining victimization, verbal and social bullying, causes of bullying, coping, and frustration with school resources dealing with aggressive behavior. Recommendations for addressing potential detrimental outcomes of bullying behavior and for improving perceptions of school climate are provided.     

Toddlers’ Temperament Profiles: Stability and Relations to Negative and Positive Parenting

This study investigated the type and stability of temperament profiles in toddlers, and relations of profile probability to negative and positive parenting trajectories. Mothers (N = 96) rated their child’s (41 girls and 54 boys) Sociability, Anger Proneness, and Activity Level four times during 1 year. The assessment of parenting included both maternal self-reports and observational measures. Latent profile analysis indicated three child temperament profiles: a well-adjusted ‘typical’ profile, an ‘expressive’ profile with heightened externalizing problems, and a ‘fearful’ profile with heightened internalizing problems. Although toddlers’ profile classifications were highly stable across 1 year, individual differences in (changes in) toddlers’ temperament profile probability occurred. We identified negative and positive parenting as environmental mechanisms that were related to the development of temperament profiles over time. These results support the notion that, in addition to having a genetic base, temperament is subject to maturation and experience over time.     

Depressive Symptoms Following Coping with Peer Aggression: The Moderating Role of Negative Emotionality

The way in which children cope with peer aggression may determine their subsequent adjustment, but different forms of coping may be more or less effective for particular children. This research examined whether the contribution of children’s coping to subsequent depressive symptoms was contingent on children’s temperament (i.e., level of negative emotionality; NE) and gender. Children (N?=?235, 102 boys, 133 girls, M?=?7.94 years, SD?=?0.33) reported on exposure to peer victimization. Parents rated children’s NE and depressive symptoms, and teachers rated children’s coping. For girls with high NE, problem solving protected against depressive symptoms whereas seeking retaliation heightened risk for depressive symptoms. Advice seeking protected children with low NE against depressive symptoms whereas ignoring protected children with high NE against depressive symptoms. Humor predicted fewer depressive symptoms in boys with high NE but more depressive symptoms in boys with low NE. This research helps to elucidate individual differences in the effects of coping on adjustment, and has implications for interventions aimed at reducing risk resulting from exposure to peer aggression.     

Proactive and Reactive Aggression and Physical Activity

The current study examined relations between physical activity and proactive and reactive aggression. Additionally, physical activity was examined as a potential moderator of the associations between these subtypes of aggression and peer delinquency. Relations were examined in a community recruited sample of 89 children (56% male, 74% Caucasian) ranging from 9 to 12 years of age (M = 10.44, SD = 1.14). As expected, physical activity was negatively related to proactive aggression and unrelated to reactive aggression. Moreover, physical activity moderated the relation between proactive aggression and peer delinquency, such that at high levels of physical activity, proactive aggression was unrelated to peer delinquency but at low levels of physical activity, proactive aggression was positively associated with peer delinquency. Thus, physical activity may be an important factor to consider when understanding the link between aggression and other problem behavior, as physical activity appears to impact the link between proactive aggression and delinquent peer affiliations.     

Within-Family Differences in Internalizing Behaviors: The Role of Children’s Perspectives of the Mother-child Relationship

The goal of this exploratory, within-family, longitudinal study was to examine whether children’s perspectives of the mother-child relationship explained within-family differences in children’s responses to a shared family stressor (maternal depressive symptoms) over time. Children (ages 8 to 15 years; N = 68) residing in 34 families were drawn from a general population study in the UK. Predictor variables were assessed at Time 1 and change in internalizing behavior from Time 1 to Time 2 (2 years later) was examined. As children were nested within families, data were analyzed using multilevel modeling, controlling for previous child behavior. Child perspective of the mother-child relationship, in interaction with maternal depressive symptoms, was found to explain within-family differences in internalizing over time. Children with a negative perspective (compared to mothers’ perspectives) were the most vulnerable to the adverse effects of maternal depressive symptoms.     

Stability of Early Identified Aggressive Victim Status in Elementary School and Associations with Later Mental Health Problems and Functional Impairments

Aggressive victims—children who are both perpetrators and victims of peer aggression—experience greater concurrent mental health problems and impairments than children who are only aggressive or only victimized. The stability of early identified aggressive victim status has not been evaluated due to the fact that most studies of aggressor/victim subgroups have focused on preadolescents and/or adolescents. Further, whether children who exhibit early and persistent patterns of aggression and victimization continue to experience greater mental health problems and functional impairments through the transition to adolescence is not known. This study followed 344 children (180 girls) previously identified as socially adjusted, victims, aggressors, or aggressive victims at Grade 1 (Burk et al. 2008) to investigate their involvement in peer bullying through Grade 5. The children, their mothers, and teachers reported on children’s involvement in peer aggression and victimization at Grades 1, 3, and 5; and reported on internalizing symptoms, externalizing symptoms, inattention and impulsivity, as well as academic functioning, physical health, and service use at Grades 5, 7, and 9. Most children categorized as aggressive victims in Grade 1 continued to be significantly involved in peer bullying across elementary school. Children with recurrent aggressive victim status exhibited higher levels of some mental health problems and greater school impairments across the adolescent transition when compared to other longitudinal peer status groups. This study suggests screening for aggressive victim status at Grade 1 is potentially beneficial. Further early interventions may need to be carefully tailored to prevent and/or attenuate later psychological, academic, and physical health problems.     

The Effects of Marital Conflict on Korean Children’s Appraisal of Conflict and Psychological Adjustment

This study examined the effects of marital conflict on Korean children’s psychological adjustment and appraisal of hypothetical marital conflict situations. Children between the ages of 10 and 12 were divided into “high-conflict” (n = 58) and “low-conflict” (n = 58) groups based on their self-reported degree of perceived interparental conflict in the home environment. Hypothetical marital conflict situations were provided in cartoon format, and were differentiated based conflict intensity (verbal versus physical aggression) and content (child-related conflict versus non-child-related conflict). In general, children reported greater negative affect and perceived threat to hypothetical conflict situations involving physical aggression compared to situations involving verbal conflict. In child-related conflict situations, children reported more fear of being drawn in and endorsed coping strategies that involved direct intervention. “High-conflict group” children evidenced stronger reactivity in responding to marital conflict situations in general and endorsed indirect intervention strategies—a finding previously not found in similar studies conducted with European-American children—indicating the possibility of cross-cultural difference in coping preferences in interparental conflict situations. Furthermore, “high-conflict group” children manifested more indices of maladjustment as indicated by externalizing and internalizing behavior problems, in addition to more self-reported depressive symptoms. Results highlight the effects of marital conflict on children’s psychological adjustment and indicate the possibility of cross-cultural differences in preferred coping mechanism in interparental conflict situations for Korean children.     

Dynamic Associations between Maternal Depressive Symptoms and Adolescents’ Depressive and Externalizing Symptoms

The current prospective study investigated transactional relations between maternal depressive symptoms and children’s depressive and externalizing symptoms. Participants included 240 children (M age = 11.86 years, SD = 0.56; 53.9% female) and their mothers who were part of a 6-year longitudinal study. Measures of maternal depression (Beck Depression Inventory), child depression (Children’s Depression Inventory), and children’s externalizing symptoms (Youth Self-Report Form) were assessed annually. Data analyses using dynamic latent difference score structural equation models indicated that the observed relations between mothers’ and adolescents’ symptoms were stable across the 6 years. Higher levels of maternal depressive symptoms predicted subsequent elevations in children’s depressive symptoms and in their externalizing problems over time. Among mothers with high initial levels of depression, children’s depressive symptoms predicted subsequent declines in mothers’ depressive symptoms. Children’s externalizing problems were not related to subsequent change in maternal symptoms.     

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.
