A social identity approach to explaining children's aggressive intentions

This study explored the effects of group norms, intra-group position, and age on the direct and indirect aggressive intentions of 247 children (aged 5.50 to 11.83 years). Participants were assigned to a team, with team norms (aggression vs. helping) and the child's position within the team (prototypical vs. peripheral–prototypical vs. peripheral) manipulated. Results showed that children in the aggressive norm condition reported greater aggressive intentions than those in the helping norm condition, although, when age was considered, this effect remained evident for younger, but not older, children. Similarly, intra-group position influenced the aggressive intentions of younger children only. For these children, when group norms supported aggression, prototypical members and peripheral members who anticipated a future prototypical position reported greater aggressive intentions than peripheral members who were given no information about their future position. The implications of these findings for understanding childhood aggression, and for intervention, are discussed.     

Group membership,group norms,empathy, and young children's intentions to aggress

This study assessed the effect of ingroup norms and empathy on 6 and 9‐year‐old children's (N=161) attitudes and aggressive intentions toward outgroup members. Prior to an intergroup drawing competition against an outgroup, participants' empathy was measured, and they were randomly assigned to a simulated group with a norm of direct or indirect aggression, or no aggression norm. Results indicated participants' attitudes were less positive toward the outgroup vs. the ingroup, and that both direct and indirect aggressive intentions were displayed toward the outgroup. Most importantly, the ingroup was liked less when it had an aggression norm, and the participants' aggressive intentions were not enhanced by the group aggression norm. Empathy was a significant negative predictor of direct but not indirect aggression intentions. Implications for understanding the instigation and inhibition of children's aggression intentions are discussed. Aggr. Behav. 35:244–258, 2009. © 2009 Wiley‐Liss, Inc.     

Social group norms,school norms,and children's aggressive intentions

This study examined whether the effect of social group norms on 7‐ and 10‐year‐old children's aggression can be moderated or extinguished by contrary school norms. Children (n=384) participated in a simulation in which they were assigned membership in a social group for a drawing competition against an outgroup. Participants learnt that their group had a norm of inclusion, exclusion, or exclusion‐plus‐relational aggression, toward non‐group members, and that the school either had a norm of inclusion, or no such norm. Findings indicated that group norms influenced the participants' direct and indirect aggressive intentions, but that the school norm moderated the group norm effect, with the school's norm effect tending to be greater for indirect vs. direct aggression, males vs. females, and younger vs. older participants. Discussion focused on how school norms can be developed, endorsed, and presented so that they have their most lasting effect on children. Aggr. Behav. 36:195–204, 2010. © 2010 Wiley‐Liss, Inc.     

Associations Between Proactive and Reactive Aggression and Risky Sexual Behavior Among Emerging Adults

This study examined associations between proactive and reactive aggression and types of risky sexual behavior. Additionally, gender was examined as a moderator of these associations. The sample included emerging adults (N = 232; male = 132) ranging from 18 to 25 years of age. Of the overall sample, 155 individuals (53.5% male) reported engaging in sexual intercourse. Proactive, but not reactive, aggression was uniquely associated with 4 types of risky sexual behavior (i.e., ever engaging in sexual intercourse, number of lifetime sexual partners, number of partners within past 3 months, and frequency of contraception use). Further, associations with number of sexual partners were strongest when levels of reactive aggression were low. With regard to gender differences, proactive aggression was associated with lower likelihood of contraception use in males. Gender also moderated the association between reactive aggression and number of lifetime sexual partners. Implications and future directions are discussed.     

Testing a Bifactor Model of Relational and Physical Aggression in Early Childhood

Different approaches have been used to classify children as relationally aggressive, physically aggressive, or both relationally and physically aggressive (co-occurring aggression). The goal of the current study (N = 164, 50.9% boys, M _age = 47.75 months, SD = 7.37) was to test a bifactor model of aggression, which allows for aggression to be assessed dimensionally, and postulates a co-occurring aggression factor as well as unique relational and physical aggression factors, during early childhood. Aggression was measured using reliable observer and teacher reports of physical and relational aggression subscales. The two-factor model was an adequate fit to the data but the bifactor model was a significant improvement in model fit compared to the two-factor model. Alternative statistics for evaluating bifactor models were used in the current study. The measurement invariance (e.g., configural invariance, metric invariance, and scalar invariance) of the bifactor model was tested across gender and results from the bifactor model using teacher report showed that the model was invariant across gender. Lastly, the criterion validity of the model was examined by evaluating the relations between the bifactor model and observations of physical and relational aggression and results generally supported the validity of the bifactor model. Overall, results suggest that a bifactor model of aggression may be a useful method for studying aggression in early childhood.     

The Role of Intimate Exchange in the Link Between Reactive Aggression and Child Depressive Symptoms

Although the link between reactively aggressive behavior and depressive symptoms in childhood has been demonstrated in previous work, few studies have examined how peer factors may influence this association. Examining the role of peers in the link between reactive aggression and depressive symptoms is necessary, as peers have been found to buffer the impact of factors that contribute to depressive symptoms in childhood. Accordingly, we examined whether intimate exchange with a best friend moderated the association between reactive aggression and depression in childhood in a sample of 115 children (aged 5–14; M = 8.88; 87 % minority; 53 % male) who attended a community based summer program. Consistent with expectation, reactive aggression was positively associated with child depressive symptoms whereas proactive aggression was negatively associated with depressive symptoms. Further, the interaction between intimate exchange and reactive aggression was associated with child depressive symptoms. Specifically, the association between reactive aggression and depressive symptoms was weaker when levels of intimate exchange were high. Thus, the current study suggests that close peer relationships may help to buffer the link between reactively aggressive behavior and depressive symptoms. Implications for findings include the need to target friendships to help prevent depressive symptoms for reactively aggressive youth.     

Relation Between Aggression Exposure During Youth and Later Resting Skin Conductance Levels

Recent research efforts have focused on examining the relationship between environmental and physiological factors to better understand the effect that childhood chronic stress might have on adult health outcomes. This study examines the relation between childhood parental aggression exposure and the sympathetic nervous system (SNS), as measured by resting skin conductance levels (SCLs). Participants (N = 155) completed retrospective self-report measures of childhood exposure to interparental aggression and physically aggressive parenting. The 2-way interaction between exposure to physically aggressive parenting and interparental aggression accounted for unique variance in adulthood SCL. Sex differences emerged in this relationship. Results suggest that the type of aggression exposure might play an important role in the relationship between stressors in youth and resting SNS activity in adulthood. Future research areas are identified, including the need to examine plasticity in the SNS depending on the age of experienced aggression and the age of intervention.     

Humility attenuates negative attitudes and behaviors toward religious out-group members

Humility is marked by the regulation of selfish impulses for the sake of others, including holding a modest view of one’s beliefs (and their relative strengths and weaknesses). In three studies, we evaluated the extent to which humility attenuates negative attitudes, behavioral intentions, and behaviors toward religious out-group members. In Study 1 (N = 159), humility regarding religious beliefs was associated with positive attitudes toward religiously different individuals. In Study 2 (N = 149), relational and intellectual humility were associated with less aggressive behavioral intentions in a hypothetical situation in which their cherished beliefs were criticized. In Study 3 (N = 62), participants implicitly primed with humility administered significantly less hot sauce (a behavioral measure of aggression) to a religious out-group member who criticized their cherished views relative to participants in the neutral prime condition. We highlight the importance of humility in promoting positive attitudes and behaviors toward religious out-group members.     

A daily diary investigation of self-reported alcohol-related direct and indirect aggression

Research supports the relationship between alcohol use and direct aggression, however, scant research has examined the association between alcohol use and indirectly aggressive behavior. Further, extant research has relied on retrospective reporting of behaviors, which may be subject to recall bias. The daily diary methodology enables the assessment of both the between- and within-subject variation, as well as reduces the likelihood of biased reporting. Consequently, the current study utilized a daily diary design to examine (a) associations between daily alcohol use and alcohol-related aggressive behaviors (i.e., direct and indirect); and (b) the co-occurrence of alcohol-related direct and indirect aggression. Participants were 105 (80% female) college student drinkers. Students completed baseline questionnaires and up to 14 consecutive, daily surveys regarding their previous day alcohol use, alcohol-related direct aggression, and alcohol-related indirect aggression. Findings revealed that alcohol use was associated with same day alcohol-related direct and indirect aggression, after controlling for baseline alcohol use. Self-reported alcohol-related direct aggression was more likely to occur on days in which self-reported alcohol-related indirect aggression occurred, after controlling for dispositional aggression, trait self-control, and baseline alcohol use. Results of the study suggest that, similar to alcohol-related direct aggression, alcohol use is associated with an increased likelihood of alcohol-related indirect aggression. Further, the co-occurrence of alcohol-related indirect and direct aggression supports that individuals may be engaging in multiple types of aggressive behaviors. Findings extend previous cross-sectional and qualitative research suggesting that indirect aggression may co-occur, perhaps increasing in severity.     

Evaluating the Relationship Between Childhood Abuse and Neglect,Interpersonal Hostile-Dominance,and Aggression in Psychiatric Hospitals

This study examined whether interpersonal hostile-dominance (HD) mediated the relationship between childhood trauma and aggression in 200 psychiatric inpatients (M age = 38.32 years, 66% male). Childhood emotional (50.5%), physical (42.0%), and sexual (42.0%) abuse, and emotional (46.5%) and physical (41.0%) neglect of moderate to extreme severity was reported. More severe emotional, physical, and sexual abuse, and physical neglect in childhood were associated with higher HD. Higher levels of HD and all forms of childhood abuse and neglect were associated with aggression; HD mediated the relationship between childhood emotional abuse, sexual abuse, and physical neglect and aggression. Findings highlight the high prevalence of childhood trauma in adult psychiatric inpatients. Further, childhood trauma contributes to HD, which increases the risk of aggression.     

Incongruence between workload and occupational norms for time pressure predicts depressive symptoms

Workplace aggression poses a significant challenge to organizations due to its potential impact on employees' mental and physical well-being. Using two studies, this article investigates whether emotion regulation could alleviate the negative effects of exposure to workplace aggression on employees' experience of strain, among social workers (N = 77) and emergency services personnel (N = 70). As predicted from coping theories of emotion regulation, Studies 1 and 2 showed that using the emotion regulation strategy of reappraisal during interactions with individuals from inside the organization (e.g., coworkers or managers) attenuated the workplace aggression–strain link. Conversely, but consistent with emotional labour theories of emotion regulation, engaging in reappraisal and suppression during interactions with legitimate outsiders (e.g., clients or patients) strengthened the workplace aggression–strain link. The findings have implications for both theory and practical interventions regarding workplace aggression.     

Outcome expectancies and outcome values as predictors of children's aggression

Social learning theory predicts that outcome expectancies and values should independently predict behavior, but past studies of aggression have failed to test this hypothesis specifically. We asked low–socioeconomic status children to imagine themselves engaging in aggressive behaviors and to rate the likelihood of each of a number of outcomes (outcome expectancies) and to rate how much they cared about those outcomes (outcome values). The relationship between self-reported aggression and outcome expectancies, values, and expectancy by value interactions was assessed. Expectancies, values, and their interactions were differentially related to aggression depending on the specific outcome investigated (e.g., punishment, bad feelings in self or other, prevention of future aggression, and peer respect). Results are discussed in terms of implications for theory and for future research. Aggr. Behav. 24:439–454, 1998. © 1998 Wiley-Liss, Inc.     

Can harmful intergroup behaviors truly represent the self?: The impact of harmful and prosocial normative behaviors on intra-individual conflict and compartmentalization

This research investigates how group members subjectively feel about their prosocial vs. harmful intergroup behaviors, and whether these behaviors can represent who they are more globally as a person. Three experiments tested how group norms (pro-merit/parity vs. pro-discrimination) and congruence with these norms predicted compartmentalization of these intergroup behaviors in the self and intra-individual conflict. Experiment 1 (N = 122) revealed that participants who conformed to a pro-discrimination norm reported compartmentalizing this behavior to a greater extent than participants who conformed to a pro-merit norm. Experiments 2 (N = 149) and 3 (N = 222) replicated and extended these findings in real and conflictual intergroup settings, also over and above the effect of relevant superordinate norms. Mediated moderation analyses also revealed that following discriminatory norms was associated with more intra-individual conflict, and that this conflict in turn predicted higher compartmentalization.     

Sport team identification and willingness to consider anonymous acts of hostile aggression

Previous research indicated that a sizeable minority of individuals report a willingness to consider engaging in anonymous acts of instrumental aggression directed toward players and coaches of a rival team. Individuals with a high degree of identification with their favorite team were particularly likely to consider such acts. The current investigation was designed to extend this research by examining the likelihood that individuals would consider engaging in hostile anonymous aggression. It was expected that highly identified persons would be particularly likely to consider these acts, even though the acts would not provide a competitive advantage for their team. Data collected from 175 university students confirmed the expectations. In addition, the results indicated that males were more likely than females to report a willingness to consider the hostile aggressive acts and that participants were more likely to report a willingness to engage in less destructive acts (e.g., tripping an opposing player or coach) than more destructive acts (e.g., murdering an opposing player or coach).

Loyal peripherals? The interactive effects of identification and peripheral group membership on deviance from non-beneficial ingroup norms

For ensuring the well-being of groups, people are needed who deviate from ingroup norms that harm the group (“loyal deviance”). Qualifying previous results that loyal deviants have to be highly identified with the group, we hypothesize and show that this is only true when group members at the same time feel that they are highly prototypical for the group. No such effects occurred for peripheral members. In all three studies (N1 = 207, N2 = 115, N3 = 107), we measured people's intention to conform to a non-beneficial (vs. beneficial; Study 1) ingroup norm, self-investment in the group, and perceived (manipulated in Study 3) marginalization. Obviously, dissent from non-beneficial norms requires both a deep psychological investment in the group as well as secure ingroup membership. Implications are discussed.     

Doctor-patient relationship and quality of life in Irritable Bowel Syndrome: an exploratory study of the potential mediating role of illness perceptions and acceptance

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterised by unpredictable bowel symptoms. These can be difficult to manage, consequently impacting quality of life (QoL). In addition, a strained doctor–patient relationship is independently reported in the qualitative literature. Given the doctor is often the first port of call for people with IBS, a difficult relationship may influence subsequent IBS management. Research suggests illness perceptions are important in determining IBS outcomes in therapy; however, their association with doctor–patient relationship and QoL is yet to be investigated. This exploratory study aimed to investigate the association between these constructs in IBS, as well as potential mediation by illness perceptions. Online questionnaires measuring doctor–patient relationship, illness perceptions, acceptance and QoL, were completed by 167 participants who reported an IBS diagnosis (144 female, mean age = 44.22 years, SD = 15.91 years). Bootstrapped pathway analysis was used to model the relationship and mediation effects. There was a significant positive correlation between patient–doctor relationship and QoL, r = .258, n = 167, p = .001. There was a significant indirect effect between doctor–patient relationship and QoL through illness coherence and acceptance (bootstrapped estimate = .058, 95%CI Lower-Upper = .02, .095, p = .002). No other indirect effects were observed in combination with good fit indices for the other illness perceptions. Findings suggest a doctor–patient relationship which fosters mutual understanding and helps patients make sense of symptoms, increases their ability to manage their IBS in a psychologically flexible manner, subsequently helping them maintain their QoL.     

Social information processing skills link executive functions to aggression in adolescents with mild to borderline intellectual disability

Executive Functions (EFs) have been associated with aggression in children and adolescents. EFs as higher-order cognitive abilities are assumed to affect cognitive functions such as Social Information Processing (SIP). We explored SIP skills as a mediating mechanism linking EFs to aggression in adolescents with mild to borderline intellectual disability (MBID with IQ from 50–84), a high risk group for aggressive behaviors and EF impairments. A total of 153 adolescents (M_age = 15.24, SD = 1.35; 54% male) with MBID participated. Focused attention, behavioral inhibition, and working memory were tested with multiple neurocognitive tasks to define latent EF constructs. Participants responded to a video-based SIP task. A latent construct for aggression was defined by caretaker, teacher, and adolescent self-reports of aggression (Child Behavior Check List, Teacher Report Form, and Youth Self Report). Structural equation modeling was performed to test mediation. Results were consistent with mediation of the relation between focused attention and aggression by SIP, namely via hostile interpretations and self-efficacy for aggression. Behavioral inhibition was linked to aggression, but this relation was not mediated by SIP. The relation between working memory and aggression was mediated by SIP, namely via hostile interpretations, aggressive response generation and via self-efficacy for aggressive responses. Bearing the cross-sectional design in mind, support was found for SIP skills as a mechanism linking EFs, in particular focused attention and working memory, to aggression, providing a viable explanation for the high vulnerability of adolescents with MBID for aggression.     

Influence of coaching efficacy and coaching competency on athlete‐level moral variables in Botswana youth soccer

This study examined coach‐perceived coaching efficacy and athlete‐perceived coaching competency, perceptions of coaches' endorsement of unfair play, and team norm for aggression on athlete‐level moral variables in Botswana youth soccer. Participants were youth soccer players (n = 506) and their coaches (n = 24). Players completed the coaching competency scale, the Judgments About Moral Behavior in Youth Sports Questionnaire, and the Team Norm Questionnaire. Coaches completed the Coaching Efficacy Scale. Multilevel analysis revealed that team norm for aggression, athletes' perceptions of their coaches' endorsement of aggression/cheating, and Game Strategy Coaching Competency were significant predictors of athletes' likelihood to aggress and perceptions of peer cheating. The findings contribute to previous research demonstrating the influence of the coach on athletes' antisocial behaviors.     

LGBTQ and Heterosexual Adolescents’ Use of Indirect Forms of Aggression

In this study, researchers investigated whether lesbian, gay, bisexual, transgender, and questioning (LGBTQ) adolescents use indirect aggression and exhibit prosocial behavior in their relationships at rates comparable to their heterosexual peers. In a sample of 666 college students (median age = 19.5 years), LGBTQ adolescents (N = 22) used relationally and socially aggressive behaviors at a level consistent with their heterosexual peers. This suggests that sexual orientation identification does not appear to differentially affect the use of indirectly aggressive behaviors during social interactions. There were also no differences in self-reported interpersonally mature behaviors (e.g., use of prosocial skills) exhibited by heterosexual and LGBTQ adolescents in this sample, which indicates that sexual and gender identity were also unrelated to the use of prosocial behaviors.     

Does bullying others at school lead to adult aggression? The roles of drinking and university participation during the transition to adulthood

This study uses a three‐wave longitudinal study of young Australians to identify developmental processes underlying the relationship between school bullying and physical aggression in early adulthood. The central question is whether and how drinking and participation in work or university study disrupt or entrench aggressive pathways from school bullying to adult aggression. Self‐report data were collected from 88 females and 63 males (N = 151) during childhood (age 10), adolescence (age 14), and early adulthood (age 20). Participants who bullied other students during childhood and adolescence, or during adolescence only, reported more physical aggression during early adulthood than those who never bullied. However, those who had bullied during adolescence only reported significantly higher adult aggression if they were also drinking at above‐average frequencies. Conversely, participation in university, compared to being in the workforce, was associated with significantly less adult aggression among the at‐risk groups. Findings suggest that particular contexts during early adulthood can offer youth on aggressive trajectories (as evidenced by bullying at school) unique opportunities to turn their behaviour around. Other contexts, however, may exacerbate aggressive behaviour patterns.
