Children's Friends and Behavioral Similarity in Two Social Contexts

The general purpose of this study was to examine similarity between friends with respect to behavior. The specific goals were to consider; 1) different sources of evaluation (peer ratings and direct observations); 2) different social contexts (classroom and play group); and 3) different subtypes of aggressive behavior (proactive and reactive aggression). In the first phase of the study, sociometric assessments and peer evaluations of behavior were conducted in the school setting with third-grade boys and girls (n - 268). In the second phase, a subsample of boys participated in a series of play group sessions (n = 66). Direct observations and peer ratings of children's behavior were conducted in those sessions. Results showed in both social contexts a tendency towards similarity among friends, especially with respect to aggressive behavior. Separate analyses for subtypes of aggressive behavior revealed that the similarity hypothesis applied for proactive aggression but not for reactive aggression.     

Reactive and proactive aggression in children with and without ADHD and negative emotional lability

Children with attention‐deficit/hyperactivity disorder (ADHD) exhibit marked difficulty with frequent and intense shifts in negative or positive emotions, referred to as emotional lability. This study examines the relationships between negative emotional lability (NEL), ADHD, and reactive and proactive aggression. A community sample of 96 children (53 with ADHD, 43 control) ages 8–12 and their parents completed a baseline session include a diagnostic structured interview and the Reactive–Proactive Aggression Questionnaire (RPAQ). Parents then rated their child's NEL using the Positive and Negative Affect Scale as part of an Ecological Momentary Assessment protocol 3 times a day for 28 days. Seventy‐three participants (37 with ADHD, 36 control) completed the RPAQ at follow‐up. Hierarchical regression analyses indicated that NEL significantly and independently estimates reactive aggression at baseline and follow‐up, regardless of ADHD status. NEL and ADHD status significantly estimates concurrent proactive aggression, but not at follow‐up. Results of this study suggest that NEL accounts for a significant amount of the variability in reactive aggression, a common difficulty in children with ADHD. Further, individuals that are reportedly emotionally labile become more reactively aggressive over time. Both ADHD diagnostic and NEL are predictors of proactive aggression at baseline, although no interaction occurred.     

Media Exposure, Aggression and Prosocial Behavior During Early Childhood: A Longitudinal Study

Preschool children (N = 78) enrolled in multi‐informant, multi‐method longitudinal study were participants in a study designed to investigate the role of media exposure (i.e., violent and educational) on concurrent and future aggressive and prosocial behavior. Specifically, the amount of media exposure and the nature of the content was used to predict concurrent and future physical, verbal and relational aggression as well as prosocial behavior for girls and boys. This two‐year longitudinal study found that media exposure predicted various subtypes of aggression and prosocial behavior. These findings are qualified by the gender of the focal child. That is, parental reports of media exposure were associated with relational aggression for girls and physical aggression for boys at school. Ways in which these findings extend our understanding of the role of media during early childhood are discussed.     

Bullying and Victimization Among School-age Children: Stability and Links to Proactive and Reactive Aggression

The main aim of the study relates to the links between bullying and victimization on the one hand and reactive and proactive aggression on the other. In addition, we also investigated stability and incidence of bullying and victimization. At age 7, 236 children were rated on bullying and victimization using peer reports. At age 8, 242 children were rated again. Two hundred and fifteen children (114 girls and 101 boys) were present at both time points. Reactive and proactive aggression was assessed by teachers. The results showed that bullies and bully/victims were both reactively and proactively aggressive, while victims were only reactively aggressive. A moderate degree of stability of bullying and victimization was found, with bullying being more stable than victimization. Boys were more often bullies than girls and more stable than girls in victimization. Stable victims and stable bully/victims were more reactively aggressive than their unstable counterparts. The relevance of the outcomes to preventing future maladjustment and suggestions for further research are discussed.     

The Relations among Observational, Physiological, and Self-Report Measures of Children's Anger

Our first goal was to examine the relations among observational, physiological, and self‐report measures of children's anger. Our second goal was to investigate whether these relations varied by reactive or proactive aggression. Children (272 second‐grade boys and girls) participated in a procedure in which they lost a game and prize to a confederate who cheated. Skin conductance reactivity, heart rate reactivity, self‐reports of anger, angry facial expressions, and angry nonverbal behaviors were measured for each turn of the game. We used multi‐level regressions to calculate the relations among the 10 pairs of the five anger variables over the course of the game. Six of the 10 pairs of anger variables were positively related. These findings suggest that measuring children's anger using any one approach may not capture the full complexity of children's overall experience and expression of anger. Furthermore, three of the 10 relations were stronger at higher levels of reactive aggression, although none varied by proactive aggression. These findings suggest that reactive aggression is related to greater cohesiveness in the experience and expression of anger than is proactive aggression.     

Patterns of Reactive and Proactive Aggression in Young Adolescents in Singapore

The authors investigated the patterns of reactive and proactive aggression exhibited by young male (N = 604) and female (N = 544) adolescents in Singapore. Self‐report measures of reactive and proactive aggression, behavioral and emotional adjustment, parenting styles, and delinquency were administered to students aged 13–14. Using cluster analysis, three distinct patterns of aggression emerged: a low aggressive group, a combined aggressive group with high reactive and proactive aggression, and a reactively aggressive group with low proactive and high reactive aggression. The two aggressive groups showed similar disturbances in adjustment and delinquency, but the combined group showed the greatest disruptions. Findings indicate cross‐cultural stability of patterns of aggression as well as the usefulness of the reactive/proactive distinction in early identification of individuals with adjustment problems.     

Social intelligence as moderator in the relation between narcissism and aggression in at-risk adolescents

This study examined the moderating role of social intelligence (SI) in the associations of grandiose and vulnerable narcissism (VN) with peer-reported overt and relational aggression (RA). The sample consisted of 286 adolescents aged 15 to 19 recruited from a residential program for youth who have dropped out of school. Results showed that whereas grandiose narcissism (GN) was related to both forms of aggression, VN was related to neither overt nor RA. However, SI moderated the relation between VN and both forms of aggression such that SI works as either a risk or protective factor for adolescents with higher levels of narcissism depending on the subdimensions of SI and aggression. The findings indicate that SI may play a role in how adolescent peers perceive the behavior of relatively narcissistic individuals.     

Actualization of Social Cognitions into Aggressive Behavior toward Disliked Targets

The basic premise that social cognitions guide behavior (aggression) was evaluated within relationships marked by dislike. At Time 1, a disliked target was identified for each participant (195 fifth‐grade children; 109 boys; 11–12 years old at Time 1) who then responded to questions about different aggression‐supporting social cognitions with regard to the chosen target. In addition, aggression directed at the identified peer (from the disliked child's perspective) was measured twice over a one‐year interval. Our results show that aggressogenic thought predicts increases in aggression only when the target is chronically disliked. Moreover, within chronically disliked relationships, the actualization of aggressogenic thought is maximized when children have high initial levels of reactive (in the case of hostile attributions) and proactive aggression (in the case of self‐efficacy beliefs), and when targets are initially high on reactive aggression. These findings suggest that social cognitions, assessed within a specific relationship context, can have more predictive validity than traditionally used decontextualized measures.     

Associations between Sadness and Anger Regulation Coping, Emotional Expression, and Physical and Relational Aggression among Urban Adolescents

This study examined associations between self-reports of sadness and anger regulation coping, reluctance to express emotion, and physical and relational aggression between two cohorts of predominantly African-American fifth (N  =  191; 93 boys and 98 girls) and eighth (N  =  167; 73 boys and 94 girls) graders. Multiple regression analyses indicated unique associations between relational aggression and expressive reluctance and sadness regulation coping. In contrast, physical aggression, but not relational aggression, was associated with anger regulation coping. These relations did not differ across gender, but the strength of the association between anger regulation coping and physical aggression varied by grade. Sadness regulation coping moderated the association between expressive reluctance and relational aggression. Conversely, anger regulation coping moderated the relation between expressive reluctance and physical aggression; however, the strength of this relation differed by gender. These findings have important implications for intervention efforts.     

Understanding Popularity and Relational Aggression in Adolescence: The Role of Social Dominance Orientation

This study investigated a potential moderator of the association between popularity and relational aggression: social dominance orientation (SDO), the degree to which an individual endorses the importance of social hierarchy. One hundred eighty‐five ninth graders completed a sociometric assessment of RA and popularity, and a self‐report SDO measure. SDO was positively associated with popularity for both boys and girls, and with RA for girls. Popularity and RA were positively correlated for both genders. Regression analyses showed that SDO moderated the association between popularity and RA for girls, but not for boys. Girls who were both popular and who were social dominance‐oriented were particularly high in peer‐nominated RA. SDO may provide a useful framework for understanding the role of popularity in adolescent peer groups.     

Who Dislikes Whom, and For Whom Does It Matter: Predicting Aggression in Middle Childhood

This study investigated the role of mutual dislike dyads (MDDs) in the development of aggressive behavior across the middle childhood years. Of particular interest was whether involvement in MDDs predicted later aggression, and whether the magnitude of the association between MDDs and later aggression varied based on characteristics of target children and 'others' involved in their MDDs. Data were collected on a community sample of 453 children participating in an ongoing longitudinal study. Classroom peer nomination and rating-scale measures were collected in kindergarten through third grade; aggressive behavior problems were assessed via teacher ratings in the early elementary years (kindergarten and first grade) and late elementary years (fourth and fifth grade). MDD involvement in the middle elementary years (second and third grade) was associated with higher levels of aggression in the late elementary years among boys (but not girls), and these predictions held after controlling for group-level peer disliking in the middle elementary years, aggression in the early elementary years, and demographic variables. The association between MDD involvement and subsequent aggression was also qualified by the aggressiveness of others in children's MDDs: Having more MDDs predicted later aggression only among boys whose MDDs involved mostly non-aggressive others.     

Aggression in toddlers: Associations with temper loss and parent-child conflict

Using a normative US sample of 477 mothers of 6- to 24- month-old children, we explored the relations among toddlers’ physical aggression, child temper loss, and parent-child conflict to gain a better understanding of how aggression develops from infancy to toddlerhood. An inventory of specific aggressive acts was subject to factor analysis to test whether the acts clustered as hypothesized. Consistent with our hypothesis, confirmatory factor analyses supported the distinction between the two types of aggression, directed and exploratory physical aggression. Although the two types were correlated, they showed differential associations with temper loss and parent-child conflict consistent with theory. Directed aggression had a relatively stronger relation with child defiance and temper loss than did exploratory aggression. Moreover, the association between directed aggression and defiance was stronger for older children. The findings from this cross-sectional study provide preliminary support for two forms of early aggression that may differ in trajectory and context.     

The Relationship Between Indirect and Physical Aggression on Television and in Real Life

Viewing indirect aggression on television has been shown to have negative short‐term effects on a viewer's subsequent aggressive behavior; however, the longer term relationship between viewing indirect aggression on television and in real life has not yet been examined. Three hundred and forty‐seven adolescents, aged 11–14, were asked to list their five favorite television programs. These programs were analyzed for the amount and type of aggression they contained. Peer‐nominated indirect aggression was predicted by other aggressive behavior, sex, and televised indirect aggression. In particular, indirectly aggressive girls viewed more indirect aggression on television than any other group. Peer‐nominated physical aggression was predicted by other aggressive behavior and sex, but not by televised physical or indirect aggression. This study provides a starting point for future long‐term research on the effect of viewing indirect aggression in the media.     

A Latent Class Analysis of Factors Associated with Levels of Aggression among Low-Income African American Youth in Chicago

Abstract

African American youth are often stereotyped as being more aggressive than and experience more severe negative social sanctions relative to their European American peers. This cross-sectional study assessed self-reported levels of aggression among a sample of 538 low-income African American youth in Chicago, and employed latent class analysis to determine groups of aggression. Major study findings showed low, middle high aggression group. The largest number of youth fell within the low aggression group. Social factors (e.g., low student-teacher connectedness, high risky peer norms, neighborhood violence, and family conflict) were associated with inclusion in the high aggression group. Intrapersonal factors (e.g., depression, anxiety, post-traumatic stress disorder) were associated with inclusion in the middle aggression group. Future longitudinal research should examine what factors are associated with movement across aggression groups and capitalize upon knowledge gained in the current study to develop interventions.     

Top Ten Challenges for Understanding Gender and Aggression in Children: Why Can’t We All Just Get Along?

This essay identifies ten significant methodological challenges for understanding aggression and gender. In light of the recent explosion of research on indirect/relational/social aggression, it seems important to clarify gaps in our current understanding and to identify promising methods by which better answers might be found. The discussion begins with basic issues of definitions, contexts and subtypes, moves on to points concerning sampling and measures, and addresses whether current evidence warrants deciding that girls are as aggressive as boys. We conclude that although research has shown that the majority of girls' aggression takes indirect/relational/social forms, it is premature to conclude that boys do not also engage in these behaviors. We caution against assuming that physical and indirect/relational/social aggression are comparable in their developmental origins and consequences, and urge researchers to consider that fully understanding indirect/relational/social aggression might require different conceptual frameworks and research methods.     

Relational Aggression, Relational Victimization, and Language Development in Preschoolers

We investigated language development, relational aggression, and relational victimization in ethnically, socioeconomically diverse preschoolers. Relational aggression was positively related to language development. Girls were more relationally aggressive than boys, and higher‐socioeconomic status (SES) children were more relationally aggressive and victimized than lower‐SES children. Neither gender nor SES conclusively moderated the relation between language and relational aggression, though some findings suggest the possibility of stronger relations among boys and lower‐SES children. Teachers agreed on ratings of relational aggression and relational victimization to a moderate extent.     

Maternal Sensitivity Moderates the Relation between Negative Discipline and Aggression in Early Childhood

Three models regarding the relation between maternal (in)sensitivity, negative discipline, and child aggression were examined in a sample of 117 mother–child pairs with high scores on child externalizing behavior: (1) Sensitivity and discipline are uniquely related to child aggression (the additive model); (2) the relation between discipline and aggression is moderated by maternal sensitivity (the moderating model); (3) the relation between sensitivity and aggression is mediated by maternal discipline (the mediating model). Parenting and child aggression were observed when the children were on average 26.71 months old (range of 13.58 to 41.91 months) and again one year later. Results supported the moderating model. More negative discipline was related to more child aggression one year later, but only when mothers were insensitive. This finding supports the idea that the affective context is important for the impact of negative discipline on child development.     

Hostile interpretation as a transdiagnostic factor for cooccurring anxiety in boys with aggressive behavior problems

Many children with aggressive behavior problems also suffer from anxiety. This cooccurrence may perhaps be explained by transdiagnostic factors. Identifying these factors seems crucial, as they may be important targets to treat these cooccurring problems effectively. This two-study paper investigates whether hostile interpretation of others’ intentions is a transdiagnostic factor for cooccurring aggression and anxiety problems, examining two samples of boys in middle childhood. We assessed boys’ aggression and anxiety using teacher-report in Study 1 (N = 84, M_age = 10.10), and parent-report in Study 2 (N = 115, M_age = 10.55). In both studies, we assessed hostile interpretation using vignettes describing ambiguous provocations by peers. Both studies revealed a strong association between aggression and anxiety problems, underscoring the necessity to examine factors that can explain this cooccurrence. However, in neither study was this association reduced when we added hostile interpretation to the model, suggesting that hostile interpretation did not function as a transdiagnostic factor in our samples. One possible explanation for these findings is that hostile interpretation predicts both aggression and anxiety problems, but in different children. We, therefore, encourage scholars to conduct more research to explain the high comorbidity of aggression and anxiety problems in children. Future research should also examine hostile interpretation as predictor or transdiagnostic factor for aggression and anxiety problems in more diverse population, including girls and other age groups.     

The distinction between provoked and unprovoked aggression in toddlerhood,and associations with empathy-related processes

Physical aggression in toddlerhood has received considerable attention in the past 20 years. The underlying theme has been that toddlers behave aggressively due to not yet being able to regulate their frustration. However, there is some evidence to suggest that early aggression can occur for other reasons. In this study, we tested the distinction between provoked and unprovoked aggression in toddlerhood, and examined whether different empathy-related processes would show unique associations with each type of aggression. Participants were 200 mothers of children aged 15–21 months (M_age = 18.32 months, SD = 1.75) who completed measures of provoked and unprovoked aggression, and empathy-related processes. We found that the two-factor aggression model fit the data well. In addition, when controlling for the overlap between other-oriented empathy and personal distress, other-oriented empathy demonstrated a negative association with unprovoked aggression, and personal distress showed a positive link with provoked aggression. Our findings underscore the importance of studying early physical aggression in a more nuanced way to better understand different functions it may serve in toddlerhood.     

Interplay between Friends' Aggression and Friendship Quality in the Development of Child Aggression during the Early School Years

The aim of this study was to investigate the unique and combined role of friendship quality and friends' aggression in regard to the persistence of young children's physical aggression from kindergarten to grade 2. The sample included 1555 children (808 girls) assessed annually using teacher ratings. Two theoretical perspectives (i.e., the social learning and the social bonding perspectives) served as frameworks to guide the analyses and interpret the results. In line with the social learning perspective, friends' aggression was related to a significant increase in children's physical aggression. However, in line with the social bonding perspective, good friendship quality played both a compensatory and a protective role, by, respectively, reducing children's initial level of physical aggression and by mitigating, albeit marginally, the associations between friends' and children's physical aggression. These results suggest that fostering a positive relationship between friends in the early school years may decrease physical aggression even if the friends are aggressive.
