The impact of violence exposure on aggressive behavior through social information processing in adolescents

Polygenic risk and hostile environments: Links to stable and dynamic antisocial behaviors across adolescence

Adverse environments are linked to elevated youth antisocial behavior. However, this relation is thought to depend, in part, on genetic susceptibility. The present study investigated whether polygenic risk for antisociality moderates relations between hostile environments and stable as well as dynamic antisocial behaviors across adolescence. We derived two antisocial-linked polygenic risk scores (PRS) (N = 721) based on previous genome-wide association studies. Forms of antisocial behavior (nonaggressive conduct problems, physical aggression, social aggression) and environmental hostility (harsh parenting and school violence) were assessed at age 13, 15, and 17 years. Relations to individual differences stable across adolescence (latent stability) vs. time-specific states (timepoint residual variance) of antisocial behavior were assessed via structural equation models. Higher antisocial PRS, harsh parenting, and school violence were linked to stable elevations in antisocial behaviors across adolescence. We identified a consistent polygenic-environment interaction suggestive of differential susceptibility in late adolescence. At age 17, harsher parenting was linked to higher social aggression in those with higher antisocial PRS, and lower social aggression in those with lower antisocial PRS. This suggests that genetics and environmental hostility relate to stable youth antisocial behaviors, and that genetic susceptibility moderates home environment-antisocial associations specifically in late adolescence.

Perpetration of Adolescent Dating Violence: Child Abuse, Attitudes, Impulsivity, Reactive and Proactive Aggression; Automatic or Complex Processes?

Adolescent dating violence (ADV) research has neglected the environmental factors at play in contexts of perpetration. This study, conducted in Chile, investigated the socio-cognitive processes inherent to the relationship between child abuse and ADV perpetration by examining the association between child abuse, impulsivity, reactive aggression, proactive aggression, attitudes that rationalize or justify ADV, and actual ADV perpetration. Data were collected from 655 adolescents using self-reported measures of child abuse, impulsivity, reactive and proactive aggression, attitudes justifying ADV, and ADV perpetration using structural equation modeling. Having experienced child abuse predicted higher levels of impulsivity, which in turn predicted higher levels of aggressive traits, both for reactive and proactive aggression. Proactive aggression predicted higher levels of ADV perpetration, whereas reactive aggression did not. While we did not find that child abuse predicted a greater propensity for ADV, nor that such a disposition indicated a higher level of proactive aggression by influencing ADV perpetration, we did find that a positive attitude toward ADV predicted a higher frequency of ADV perpetration. Our results suggest that the socio-cognitive process underlying ADV involves automatic and complex processes stemming from child abuse, thus linking environmental and individual factors.

Examining the causal effects of exposure to violence on crime among youth involved in the justice system: Experienced, witnessed, and experienced-witnessed violence

Previous studies on exposure to violence lack a nuanced understanding of the causal effects of different exposure types on offending behaviors. This study, drawing on Pathways to Desistance Study (PDS) data tracking 1354 adjudicated youths aged 14-18 over 7 years, explores the contemporaneous (cross-sectional), acute (after 1 year), enduring (after 3 years), and long-term (after 6 years) causal effects of violence exposure on property and violent offending. The sample, predominantly male (86%), consisted of White (20%), Black (42%), and other (38%) individuals. The generalized propensity score is used to match unbalanced covariates across multiple exposure types, namely noninvolved (n = 392), witnessed (n = 577), experienced (n = 31), and experienced-witnessed violence (n = 305). Results demonstrate the contemporaneous, acute, enduring, and long-term effects of violence exposure on both violent and property offending, with varying durations and strengths across exposure types. The most pronounced risk effects are immediate, diminishing over time and potentially reversing in the long term as youth transition into adulthood. Among exposure types, experienced-witnessed violence exhibits the most potent effects on offending, followed by witnessed violence and then experienced violence-a pattern consistent across the observed time points. Noteworthy is the finding that the impact of violence exposure is more pronounced for violent offending, diminishing more rapidly compared to the effects on property offending.

A Four-Wave Cross-Lagged Study of Exposure to Violent Contexts, Cognitive Distortions, and School Bullying during Adolescence

School bullying represents a widespread expression of violence in the peer context. Guided by the social-ecological model, this study investigated the longitudinal and transactional pathways linking domestic and neighborhood/community violence exposure (through direct victimization and witnessing), self-serving cognitive distortions (CDs), and school bullying perpetration. Furthermore, consistent with the previous literature, we tested the cognitive desensitization process that could develop in response to chronically violent contexts. Two four-wave cross-lagged panel mediation models were tested in a sample of 778 high school students (28.1% males; Mage [Time 1; T1] = 14.20, SD = 0.58). The results showed differential effects of multiple contexts and forms of violence exposure, with domestic violence victimization and community violence witnessing being associated with self-serving CDs and bullying perpetration over time. Moreover, significant associations between CDs and bullying perpetration over time were found, with bidirectional effects for each of these longitudinal patterns. Finally, self-serving CDs significantly mediated the relationships between both domestic violence victimization and community violence witnessing and school bullying perpetration. These findings highlight the need to consider school bullying as a social phenomenon stemming from a complex and bidirectional interplay between individuals and the environments they inhabit, confirming a basic postulate that "violence breeds violence".

Interpersonal school violence and mother-child communication about violence in relation to empathy in early adolescence

INTRODUCTION

Exposure to interpersonal violence at school has been linked with lower empathy, but less is known about factors that may moderate this relationship. Positive parent-child communication has been associated with higher empathy during adolescence and children of parents that communicate their disapproval of violent behavior respond more peacefully in situations involving violence. Mother-child communication about violence may therefore reduce the risk of desensitization to violent behavior and promote empathy in youth that are frequently exposed to violence. Thus, this study examines whether mother-child communication about violence mitigates the association between exposure to interpersonal school violence and adolescents' empathy.

METHODS

This study addressed this question using a diverse sample of early adolescents from the Southeastern United States in 2003 (N = 642; mean age 11.3 years; 52% male; 76% Black, 22% non-Hispanic White). Adolescents reported on how often they witness or experience interpersonal violence at school and how often they communicate with their mother about violence and how to avoid it. Adolescents also self-reported on their level of empathy.

RESULTS

Results from a hierarchical regression model showed that exposure to interpersonal school violence and lower mother-child communication about violence were uniquely associated with lower empathy, but communication about violence did not moderate the link between interpersonal school violence exposure and empathy. There were no sex differences in these relationships.

CONCLUSIONS

Contrary to the hypothesis, youth who experience and witness interpersonal violence at school show lower empathy independent of whether youth communicate with their mother about violence and responding to violent situations.

Bullying Victimization and Malevolent Creativity in Rural Adolescents: The Longitudinal Mediational Role of Hostile Attribution

Extensive research has documented bully victimization as a pivotal risk factor contributing to aggressive behaviors among adolescents. Particularly, the negative outcome of increased aggressive behaviors may be exacerbated when the aggressive actions are novel and difficult to detect. The present study aims to explore the complex relationships between cyberbullying and school bullying victimization and malevolent creativity and the potential mediating role of hostile attribution using two-wave longitudinal data. The present study analyzed data from 262 rural adolescents. The results revealed that cyberbullying victimization significantly predicted malevolent creativity, whereas school bullying victimization did not. Hostile attribution served as a mediator in the relationship between cyberbullying victimization and malevolent creativity in the longitudinal models. These findings provide significant implications for mitigating the negative influence of bullying victimization on the emergence of malevolent creativity in rural adolescents.

Restorative Parental Discipline and Types of Defending Bystander Intervention in Cyberbullying: The Mediate Role of Justice Sensitivity

Parental socialization strategies are critical in explaining adolescents' online behavior. This study examined the relationships between parental restorative discipline, observed justice sensitivity, and cyber-bystander defender intervention (constructive and aggressive) in cyberbullying. The sample comprised 900 Mexican adolescents (40.2% male and 58.8% female), of which 450 were from secondary school (M age = 13.6, SD = 0.8) and 450 were from high school (M age = 15.4, SD = 1.3). Structural equation modeling with latent variables was performed. Overall, the results indicate that parental restorative discipline positively relates to the observer's justice sensitivity and the adoption of constructive interventions by cyber-bystander defenders. However, restorative discipline had no significant direct relationship with aggressive intervention. Observers' justice sensitivity mediates the association between restorative parenting discipline and aggressive or constructive defender interventions. Gender does not moderate the relationship proposed in the structural model. These findings suggest that parental restorative discipline explains constructive and aggressive cyber-bystander defender interventions in cyberbullying.

The Role of Peer- and Self-Appraisals in the Association Between Maltreatment and Symptomatology

Recent research highlights the use of artificial boundaries between distinct types of adverse experiences, including forms of maltreatment. Commonly-utilized methods that isolate the impact of one maltreatment subtype over others and fail to consider the often co-occurring nature of maltreatment may not adequately capture the complex heterogeneous nature of maltreatment and may obscure understanding of developmental pathways. Moreover, childhood maltreatment is associated with the development of maladaptive peer relationships and psychopathology, with negative conceptions of relationships identified as a risk pathway. The current study utilizes structural equation modeling to examine the impact of an adapted threat versus deprivation framework for conceptualizing maltreatment via children's negative conceptions of relationships, which have not been previously tested as mechanisms in the context of this conceptual framework. Participants included 680 socioeconomically disadvantaged children who attended a week-long summer camp. Multi-informant methods were used to assess children's symptomatology and interpersonal functioning. Results did not support differences between threatening versus depriving maltreatment experiences, but indicated that all groups of children who experienced maltreatment, including those enduring both threatening and depriving experiences, showed more maladaptive functioning and more negative conceptions of relationships relative to non-maltreated peers. Results of the current study support the mediating role of children's appraisals of the self and peers in the effect of maltreatment on children's internalizing and externalizing symptomatology.

Longitudinal Associations Between Community Violence Exposure and Mental Health Problems in Inner-City Youth: Ethnicity and Gender Perspectives

There is a lack of agreement on whether children and adolescents with different cultural/ethnic backgrounds react to trauma in a similar fashion. This study adds to the existing literature by providing ethnicity and gender perspectives on the longitudinal associations between the degree of community violence exposure (CVE) and mental health problems in U.S. inner-city youth. The study was conducted on a representative sample of predominantly ethnic minority youth (N = 2,794; 54.1% female; age 11-16 years old (M [SD] = 12.77 [1.29]); 60.0% African-American, 26.1% Hispanic American, 13.9% White). Self-reported information was obtained on CVE in year 1 and on mental health problems (depressive symptoms, posttraumatic stress, alcohol use, and conduct problems) in year 1 and year 2. Multivariate analyses of covariance (MANCOVA) were used to compare mental health problems in youth from the three ethnic groups in relation to the different degrees of CVE experienced one year prior, while controlling for their baseline mental health problem levels, age, and socio-economic status. Mental health problems in year 2 increased in a similar fashion in relation to the degree of severity of CVE in year 1 in all three ethnic groups. The interaction effects suggested a gender-specific response to CVE, where girls in the three ethnic groups reported higher levels of depression and posttraumatic stress in relation to the same degree of CVE, as compared to boys. Adolescents from different ethnic backgrounds respond similarly to differing degrees of CVE with an increase in mental health problems over time. In response to a similar degree of exposure, girls tend to experience greater levels of internalizing problems than boys. Timely recognition of traumatic exposure and associated mental health problems is important for early prevention and intervention strategies.

Supporting Children Who Experience Domestic Violence: Evaluating the Child Witness to Domestic Violence Program

Impacting 1 in 4 children in the United States, childhood exposure to domestic violence predicts myriad negative sequelae. Intervening post exposure is critical to help children and their protective parent heal and avoid long-term negative consequences. Children aged 2-17 and their mothers who were victims of domestic violence participated in a 12-week group program delivered by domestic violence agency staff that provides psychoeducation on the impact of trauma and domestic violence and aims to improve parent and child well-being. The impact of the Child Witness to Domestic Violence (CWDV) program was tested in an intervention group (n = 69 children, 33 mothers) who participated in CWDV and control group (n = 80 children, 39 mothers) consisting of children whose mothers received adult-focused domestic violence services but were not enrolled in CWDV or other child-focused services. Multiple regression analyses controlling for child gender, child age, mother's age, and the outcome of interest at time 1 found that participation in CWDV program significantly predicted better child functioning as indicated by less hyperactivity (B = -.85, p = .06), fewer negative emotional symptoms (B = -1.14, p = .01), and fewer total behavioral difficulties (B = -2.48, p = .02) as well as higher maternal hope (B = .57, p = .03). These data provide promising evidence of the impact of a brief, replicable group intervention that promotes healing and well-being among children and parents exposed to domestic violence. Limitations include a quasi-experimental design and reliance on maternal report.

Gender Moderates the Association Between Exposure to Interpersonal Violence and Intermittent Explosive Disorder Diagnosis

Exposure to interpersonal violence (EIV) is a prevalent risk-factor for aggressive behavior; however, it is unclear whether the effect of EIV on clinically significant aggressive behavior is similar across gender. We examined whether gender moderates the association between experiencing and witnessing interpersonal violence and the diagnosis of intermittent explosive disorder (IED). We also examined potential pathways that might differentially account for the association between EIV and IED in men and women, including emotion regulation and social information processing (SIP). Adult men and women (N = 582), who completed a semistructured clinical interview for syndromal and personality disorders, were classified as healthy controls (HC; n = 118), psychiatric controls (PC; n = 146) or participants with an IED diagnosis (n = 318). Participants also completed the life history of experienced aggression (LHEA) and life history of witnessed aggression (Lhwa) structured interview and self-report measures of emotion regulation and SIP. Men reported more EIV over the lifetime. In multiple logistic regression analysis, experiencing and witnessing aggression within the family and experiencing aggression outside the family were associated with lifetime IED diagnosis. We found that the relationship between EIV and IED was stronger in women than in men. Affective dysregulation mediated certain forms of EIV, and this relation was observed in both men and women. SIP biases did not mediate the relation between EIV and IED. EIV across the lifespan is a robust risk factor for recurrent, clinically significant aggressive behavior (i.e., IED). However, the relationship between EIV and IED appears to be stronger in women. Further, this relation appears partially mediated by affective dysregulation.

Efficacy to avoid violence and parenting: A moderated mediation of violence exposure for African American urban-dwelling boys

We took a risk and resilience approach to investigating how witnessing physical violence influences adolescent violent behaviors overtime. We proposed efficacy to avoid violence as a major path of influence in this negative trajectory of adolescent development. We also focus on the protective roles of parenting behaviors for African American boys living in disadvantaged contexts. Most of our sample of 310 African American adolescent males (M age = 13.50, SD = .620) had experienced significant amounts of violence, but they also reported continued efficacy to avoid violence. We tested a first stage dual moderated mediation model and found that higher levels of witnessing violence lead to more violent behavior and less efficacy to avoid violence, and that efficacy was the mediator in that link. Youth who witness more violence may feel that engagement in violence is inescapable and thus may themselves end up engaging in it. These problematic long-term trajectories were moderated by parent's communication about violence and monitoring revealing possible protections for youth, and an enhancement of youths' internal strengths. Our findings propose pathways that can inform interventions that may protect African American adolescent boys against the vicious cycle of exposure to, and acts of, violence.

Violence exposure across multiple contexts as predictors of reactive and proactive aggression in Chinese preadolescents

Based on different functions of aggression, the conceptual distinction of reactive and proactive aggression has been proposed. It is widely acknowledged that adolescents' violence exposure contributes to later perpetration of aggressive behaviors. However, few studies have compared the effects of violence exposure on reactive/proactive aggression based on the forms (i.e., witnessing and being victimized) and the contexts (i.e., family, community, and school), especially in preadolescents. Thus, the relationship between two forms of violence exposure (witnessing and victimization) and later perpetrating reactive and proactive aggression were compared within and across three social contexts in a sample of Chinese preadolescents. Participants were 609 preadolescents 51.9% boys) recruited from five primary schools in China. Information on two forms of violence exposure across multiple contexts and demography were collected at Time 1 (M_age  = 10.65), and aggression data (i.e., reactive and proactive aggression) were collected a year later at Time 2. Results evidenced witnessing and being victimized by violence in the home were more consistently related to later perpetration of reactive and proactive aggression. Witnessing family violence was significantly associated with later perpetration of reactive aggression than witnessing violence in the community. Being victimized by violence in the community and the home were significantly associated with later perpetration of proactive aggression than school victimization. These findings provide a deeper understanding of the roles of both types of violence exposure across contexts in later perpetration of aggression during early adolescence.

Beliefs as Mediators of Relations Between Exposure to Violence and Physical Aggression During Early Adolescence

This study examined beliefs about aggression and self-efficacy for nonviolent responses as mediators of longitudinal relations between exposure to violence and physical aggression. Participants were a predominantly African American (79%) sample of 2,705 early adolescents from three middle schools within urban neighborhoods with high rates of violence. Participants completed measures across four waves (fall, winter, spring, and summer) within a school year. Beliefs supporting proactive aggression, beliefs against fighting, and self-efficacy for nonviolence partially mediated relations between witnessing violence and physical aggression. Indirect effects for beliefs supporting proactive aggression and self-efficacy were maintained after controlling for victimization and negative life events. Beliefs supporting proactive aggression mediated the effects of violent victimization on physical aggression, but these effects were not significant after controlling for witnessing violence and negative life events. The findings underscore the importance of examining the unique pathways from witnessing community violence versus violent victimization to physical aggression.

Intergenerational maltreatment in parent-child dyads from Burundi, Africa: Associations among parental depression and connectedness, posttraumatic stress symptoms, and aggression in children

Studies investigating the associations between histories of childhood maltreatment (CM) in parent-child dyads have primarily involved samples from high-income countries; however, CM rates are higher in low- and middle-income countries. The present study aimed to examine the (a) association between maltreatment in parents and maltreatment of their children through risk (i.e., parent depression) and protective (i.e., parent-child connectedness) factors and (b) associations between CM in children with aggression through posttraumatic stress symptoms (PTSS) and peer/sibling victimization. Participants were 227 parent-child dyads from Burundi, Africa, a low-income country. Parents were 18 years of age or older, and children were 12-18 years (M = 14.76, SD = 1.88, 57.7% female). Among parents, 20.7%-69.5% of participants reported a history of physical and emotional abuse and neglect; among children, the rates of sexual, physical, and emotional abuse ranged from 14.5% to 89.4%. A history of CM in parents was associated with CM in children, B = 0.19, p < .01, and CM in parents was indirectly associated with CM in children through parent-child connectedness, β = .04, 95% CI [.01, .10], and parental depression, β = .08, 95% CI [.03, .15]. In children, maltreatment was positively associated with peer/sibling victimization, and CM was associated with aggression, β = .07, 95% CI [.04, 0.11], through PTSS but not via peer/sibling victimization. Continued efforts to improve CM-related preventive strategies and the accessibility of prevention services are needed to reduce CM in low-income countries such as Burundi.

Additive and Interactive Effects of Victimization on Adolescent Aggression Across Social Settings

Considering that children and adolescents can face multiple exposures to violence due to their involvement in different socialization domains, this study aimed to analyze additive and interactive effects of physical and verbal victimization by parents, peers, and schoolteachers on adolescent aggression across social settings. With regard to parent-child and teacher-adolescent relationships, physical and verbal forms of aggression were differentiated, whereas aggression by and toward peers was assessed by a composite measure of overt and indirect aggression. Data were drawn from three large secondary school surveys of ninth-grade students within one federal German state conducted in the years 2013, 2015, and 2017. Based on a sample of 8,458 adolescents (mean age = 14.9 years), results provided evidence for additive as well as interactive effects of victimization across settings. Controlling for a range of risk factors associated with victimization and aggression, victimization by parents, peers, and teachers was uniquely related to adolescent aggression across social settings. In addition, three significant interaction effects were identified between different combinations of victimization: Students exposed to earlier parent-to-child physical aggression perpetrated more physical aggression toward parents within the last 12 months if they were also recently victimized by peers. Furthermore, parent-to-child physical aggression exacerbated the positive relationship between teacher-to-adolescent physical aggression and adolescent-to-teacher physical aggression. In contrast, exposure to teacher-to-adolescent verbal aggression reduced the positive link between peer-to-adolescent aggression and aggression toward peers. Findings suggest that intervention should be particularly sensitive toward multiple exposure to violence across socialization contexts, as well as toward the interdependence of cross-setting victimization.

The Interplay of Depression and Hostile Attributions in the Link Between PTSD Symptoms and Peer Victimization in Child Victims of Sexual Abuse

This study sought to test a serial mediation model in which depressive symptoms and hostile attributions mediate the relationship between post-traumatic stress symptoms and peer victimization in a sample of child victims of sexual abuse. Participants included 771 children aged 6 to 12 years old, consulting specialized intervention settings following disclosure of sexual abuse. Children completed questionnaires assessing their levels of post-traumatic stress symptoms, depressive symptoms and experiences of peer victimization in the school context. Vignettes were used to assess hostile attributions for instrumental and relational provocations. Results of the path analysis revealed that post-traumatic stress symptoms were associated with depressive symptoms, which were linked to greater hostile attributions for relational provocations, which were in turn associated to a greater likelihood of reporting peer victimization. Hostile attributions for instrumental provocations were not related to peer victimization.

Is the association between childhood maltreatment and aggressive behavior mediated by hostile attribution bias in women? A discordant twin and sibling study

Understanding the mechanisms behind aggressive behavior (AGG) is vital so that effective prevention and intervention strategies can be developed. Maltreated children are hypothesized to be prone to social information processing biases, such as hostile attribution bias (HAB), which, in turn, may increase the likelihood of behaving aggressively. The first aim of the present study was to replicate findings regarding associations between childhood maltreatment (CM), HAB, and aggression in a population-based sample of Finnish female twins and their sisters (N = 2,167). However, these associations might not be causal but instead confounded by familial factors, shared between the variables. The second aim was, thus, to test the associations when potential confounding by familial (genetic or common environmental) effects were controlled for using a multilevel discordant twin and sibling design within (a) 379 pairs of twins (n_pairs  = 239) or siblings (n_pairs  = 140), and (b) within the 131 monozygotic (MZ) twin pairs. Consistent with previous studies, HAB mediated the association between CM and AGG when familial confounding was uncontrolled. No support was found for the mediation when controlling for familial confounding. Between-pair associations were found between CM and AGG, and between CM and HAB. In addition, within-pair associations were found between HAB and AGG, and between CM and AGG, however, these were nonsignificant in the discordant MZ analysis, offering the most stringent control of familial confounding. The results indicate the necessity of taking familial confounding into account when investigating the development of AGG.

The Juxtaposition of Revenge and Forgiveness in Peer Conflict Experiences of Youth Exposed to Violence

In a sample of 95 urban Colombian mid-adolescents, this mixed-method study examined how youths' retaliatory desires and actions were juxtaposed with forgiveness and nonforgiveness in their narrative accounts of peer conflict. Quantitative analyses examined how retaliatory desire and action were associated with variations in youths' lifetime exposure to violence (ETV) and recent victimization by peers at school. These measures of violence exposure were related to revenge only in the context of unforgiven harms. Qualitative analyses explored aspects of youths' narrative accounts that may underlie the observed associations. Overall, findings suggest that ETV may interfere with youths' capacity to reflect on revenge in ways that recognize their own fallibility and thus open the door to forgiveness.

Effects of Parenting and Community Violence on Aggression-Related Social Goals: a Monozygotic Twin Differences Study

Community violence exposure and harsh parenting have been linked to maladaptive outcomes, possibly via their effects on social cognition. The Social Information Processing (SIP) model has been used to study distinct socio-cognitive processes, demonstrating links between community violence exposure, harsh parenting, and maladaptive SIP. Though much of this research assumes these associations are causal, genetic confounds have made this assumption difficult to rigorously test. Comparisons of discordant monozygotic (MZ) twins provide one empirical test of possible causality, as differences between MZ twins must be environmental in origin. The present study examined effects of parenting and community violence exposure on SIP - specifically aggressive and avoidant social goals - in a sample of 426 MZ twin dyads (N = 852 twins, 48% female). Phenotypically, we found that lower positive parenting and greater harsh parenting were associated with greater endorsement of dominance and revenge goals. We also found that indirect and direct community violence exposure was associated with greater endorsement of avoidance goals. Using an MZ difference design, we found that the relationships between lower levels of positive parenting and endorsement of dominance and revenge goals were due, in part, to environmental processes. Moreover, the relationships between the impact of indirect and direct community violence exposure and avoidance goals, as well as between the impact of indirect community violence exposure and revenge goals, appeared to be due to non-shared environmental processes. Our results establish social and contextual experiences as important environmental influences on children's social goals, which may increase risk for later psychopathology.

Contextual violence and its link to social aggression: a study of community violence in Juárez

The city of Juárez, Mexico has been immersed in an atmosphere of violence and danger for more than a decade. Due to this violence, residents of Juárez may be at risk of severe contextual victimization, which occurs when individuals are indirectly affected by the physical and socio-cultural conditions of their violent communities through second-hand information (e.g., witnessing or hearing about violent acts in their everyday life). The objective of this study was to explore the effects of contextual victimization on variables related to community violence such as aggression, post-traumatic stress disorder (PTSD), and acceptance of violence. Data were collected from a sample of university students in Juárez (n = 298) using the Aggression Questionnaire (AQ), the Acceptance of Violence Scale (AVS), Checklist for PTSD Traits scale, and the Contextual Victimization by Community Violence scale (CVCV). Participants’ responses were analyzed in structural equation models (SEM) to uncover the latent variables behind each scale and test the hypothesized effects of CVCV on PTSD, AQ and AVS. Good validity indexes and internal consistency of all instruments were confirmed. SEM show significant positive effects of contextual violence on PTSD and PTSD on the disposition to aggression, but not on the acceptance of violence. Also, the variance explained of PTSD and AQ found in the sample of women (20% of PTSD and 23% of AQ) is almost twice than in men’s sample (9% for PTSD and 14% for AQ).

Exploring parent-child agreement on reports of exposure to community violence: Utilizing a latent profile approach

Exposure to community violence (ECV) has a number of implications for children including poor mental health functioning, impaired cognition, memory, learning, and school performance (Edlynn et al, 2008 Am. J. Orthopsychiat., 78, 249-258; Gardner et al., 1996, J. Consult. Clin. Psychol., 64, 602-609). Discrepancies in child and parent reports of the child's ECV may exacerbate these adverse effects (Hill & Jones, 1997 J. Natl Med. Assoc., 89, 270-276). This study aimed to categorize dyads based on the agreement in reports of ECV. Furthermore, this study aimed to identify ethnic differences within these groups in addition to mental health issues. Four profiles, based on average exposure to violence, emerged: Low exposure (LE), moderate exposure, high exposure, and severe exposure. Ethnic differences among these profiles indicate ethnic minorities are less likely to belong to the LE profile and more likely to represent the other profiles. There were differences among profiles based on mental health functioning.

Family Violence, Sibling, and Peer Aggression During Adolescence: Associations With Behavioral Health Outcomes

Bullying and sibling aggression can appear as similar behavior, though the latter is comparatively understudied. Aligned with the Theory of Intergenerational Transmission of Violence, research suggests that exposure to family violence increases an individual's risk for perpetrating violence in their own future relationships. Additionally, Problem Behavior Theory suggests that engaging in one problem behavior (e.g., bullying) increases the likelihood of engaging in other problem behavior (e.g., substance use). In Phase 1, this study of middle school students from the U.S. examined how exposure to family violence predicted membership in latent classes of bullying and sibling aggression perpetration (N = 894, sampled from four middle schools). In Phase 2, we used mixture modeling to understand how latent classes of family violence, sibling aggression, and bullying predict future substance use, mental health outcomes, and deviance behavior later in high school. Results yielded four profiles of peer and sibling aggression: high all, high sibling aggression, high peer aggression, and low all aggression. Youth who reported witnessing more family violence at home were significantly more likely to fall into the sibling aggression only and high all classes, compared to the low all class. Phase 2 results also yielded four classes: a high all class, a sibling aggression and family violence class, a peer aggression class, and a low all class. Individuals in the high all class were more likely to experience several unfavorable outcomes (substance use, depression, delinquency) compared to other classes. This study provides evidence for pathways from witnessing violence, to perpetrating aggression across multiple contexts, to developing other deleterious mental and behavioral health outcomes. These findings highlight the negative impact family violence can have on child development, providing support for a cross-contextual approach for programming aimed at developing relationships skills.

Understanding the Buffering Effects of Protective Factors on the Relationship between Adverse Childhood Experiences and Teen Dating Violence Perpetration

Prior research has demonstrated the scope and impact of adverse childhood experiences (ACEs) on health and wellbeing. Less is known about the trajectories from exposure to ACEs, such as witnessing family conflict and violence in the community, to teen dating violence perpetration, and the protective factors that buffer the association between early exposure to ACEs and later teen dating violence perpetration. Students (n = 1611) completed self-report surveys six times during middle and high school from 2008 to 2013. In early middle school, the sub-sample was 50.2% female and racially/ethnically diverse: 47.7% Black, 36.4% White, 3.4% Hispanic, 1.7% Asian/Pacific Islander, and 10.8% other. Youth were, on average, 12.7 years old. Latent transition analysis was used to assess how trajectories of exposure to parental conflict and community violence during middle school transition into classes of teen dating violence perpetration (e.g., sexual, physical, threatening, relational, and verbal) in high school. Protective factors were then analyzed as moderators of the transition probabilities. Three class trajectories of ACEs during middle school were identified: decreasing family conflict and increasing community violence (n = 103; 6.4%), stable low family conflict and stable low community violence (n = 1027; 63.7%), stable high family conflict and stable high community violence (n = 481; 29.9%). A three class solution for teen dating violence perpetration in high school was found: high all teen dating violence class (n = 113; 7.0%), physical and verbal only teen dating violence class (n = 335; 20.8%), and low all teen dating violence class (n = 1163; 72.2%). Social support, empathy, school belonging and parental monitoring buffered some transitions from ACEs exposure trajectory classes to teen dating violence perpetration classes. Comprehensive prevention strategies that address multiple forms of violence while bolstering protective factors across the social ecology may buffer negative effects of exposure to violence in adolescence.

A Longitudinal Analysis of the Indirect Effect of Violence Exposure on Future Orientation Through Perceived Stress and the Buffering Effect of Family Participation

Exposure to violence (ETV) during adolescence has been associated with negative effects in later life, and may negatively affect an individual's future orientation. Future orientation has important health implications and warrants being studied. Yet, few researchers have examined how ETV affects an individual's future orientation as a young adult. The purpose of this study was to examine the indirect effect of ETV during adolescence on future orientation as a young adult through perceived stress. We also tested the moderating effect of family participation on the relationship between perceived stress and future orientation. Longitudinal data from a sample of 316 African American participants (42.10% male and 57.90% female, Mage = 14.76 at Wave 1) from low socioeconomic backgrounds recruited from a Midwestern school district were used in the analysis. Multigroup structural equation modeling (SEM) was used to test our hypotheses. Our findings indicated that greater ETV during adolescence is associated with higher levels of perceived stress and, in turn, a more negative outlook on one's future as a young adult. This indirect effect occurred for individuals with lower family participation, but was not evident for individuals with greater family participation. These findings provide important implications for youth development interventions.

Exposure to Family Violence and Internalizing and Externalizing Problems Among Spanish Adolescents

Exposure to intimate partner violence (IPV) and child maltreatment may have devastating consequences on children's development. The aim of this research was to examine the predictive associations between exposure to violence at home (witnessing violence against the mother and/or direct victimization by the parents) and adolescent internalizing and externalizing problems. A total of 613 Spanish adolescents (13-18 years) took part in this study. Results indicate that psychological victimization by the parents predicted an increase in anxious/depressive symptoms, aggressive and rule-breaking behavior, and substance abuse at Time 2. In addition, rule-breaking behavior predicted an increase in adolescents' substance abuse at Time 2. Concerning gender, psychological victimization predicted an increase in anxiety/depression, aggressive behavior, rule-breaking behavior, and substance abuse in boys; whereas in girls, psychological victimization only predicted an increase in anxiety/depression.

Trauma and Aggression: Investigating the Mediating Role of Mentalizing in Female and Male Inpatient Adolescents

High rates of posttraumatic stress disorder (PTSD) symptoms and elevated levels of aggression are common among youth in inpatient psychiatric settings. Several models link trauma exposure to aggression through anomalous mental state reasoning. Some theoretical frameworks linking trauma to aggression specify that the over-attribution of hostile mental states contributes to the development of aggressive behavior whereas other theories suggest that an inhibition of mental state reasoning leads to aggressive behavior. Using a sample of inpatient adolescents, the current study examined relations between PTSD symptoms and four forms of aggression, exploring the role of both over- and under-mentalizing (i.e., hypo- and hypermentalizing) as mediators and gender as a moderator. The results suggest that hypermentalizing, but not hypomentalizing, mediates the relation between trauma and aggression, extending prior research related to inpatient adolescents for the first time. Evidence of moderated mediation was noted, such that this mediational relation was evident for females but not males. The current study offers support for differential underlying causes of aggression among males and females with PTSD symptoms.

The Role of Socio-Economic Status in Adoption of Coping Strategies Among Adolescents Against Domestic Violence

In the current study, researchers explored different types of coping strategies such as problem-focused coping, emotion-focused coping, and non-constructive coping of adolescents witnessing and experiencing domestic violence. Furthermore, they tried to find out the association of socio-economic status with coping strategies against domestic violence in family sphere. A cross-sectional survey was conducted with 210 adolescents of both sexes, aged 13 to 18 years in Hafizabad city using multistage sampling technique. Multivariate analysis was used to find out the association between adolescents' resistance and resilience strategies against domestic violence. The information was collected through a structured interview schedule. This study revealed that age, gender, parents' education, and family income were major factors that influenced the adoption of coping strategy among adolescents. Overall, the study suggested that adolescents were being victimized of various forms of domestic violence frequently in Pakistan, which needs to be addressed on immediate basis through policies and programs by integrating the social institutions of family and education. Findings of the study can enable parents to nurture and support the developmental needs of children in their care. It can help youth in defending themselves from extreme violent behavior adopters and preventing them from becoming the perpetrators of the domestic violence.

How children's victimization relates to distorted versus sensitive social cognition: Perception, mood, and need fulfillment in response to Cyberball inclusion and exclusion

This study examined whether victimization is associated with negatively distorted social cognition (bias), or with a specific increased sensitivity to social negative cues, by assessing the perception of social exclusion and the consequences for psychological well-being (moods and fundamental needs). Both self-reported and peer-reported victimization of 564 participants (M_age=9.9years, SD=1.04; 49.1% girls) were measured, and social exclusion was manipulated through inclusion versus exclusion in a virtual ball-tossing game (Cyberball). Children's perceptions and psychological well-being were in general more negative after exclusion than after inclusion. Moreover, self-reported-but not peer-reported-victimization was associated with the perception of being excluded more and receiving the ball less, as well as more negative moods and less fulfillment of fundamental needs, regardless of being excluded or included during the Cyberball game. In contrast, peer-reported victimization was associated with more negative mood and lower need fulfillment in the exclusion condition only. Together, these results suggest that children who themselves indicate being victimized have negatively distorted social cognition, whereas children who are being victimized according to their peers experience increased sensitivity to negative social situations. The results stress the importance of distinguishing between self-reported and peer-reported victimization and have implications for interventions aimed at victimized children's social cognition.

The clinical utility of social information processing theory in assessing and treating offenders with autism spectrum disorder

Purpose

Social deficits are central within conceptualisations of autism spectrum disorder (ASD), and separately linked to offending behaviour. Social problem-solving interventions are often used with offenders, but little research has examined the social information processing (SIP) skills of individuals with ASD and a history of criminal offending behaviours. The paper aims to discuss this issue.

Design/methodology/approach

This conceptual paper will introduce the SIP model, review SIP research as applied to those with ASD and in forensic populations, and further consider the relevance to the assessment and treatment of offenders with ASD.

Findings

Difficulties in all areas of the SIP model are noted in ASD and research suggests these difficulties may be directly linked to behaviour.

Practical implications

It is possible that identifying SIP abilities and deficits could improve the effectiveness of rehabilitation programmes for this group.

Originality/value

This paper reviews the utility of social information models in the offending behaviour of people with ASD.

Walking Away Hurt, Walking Around Scared

Using a person-centered approach, we examine phenomenological variations in exposure to violence for Black males and describe risk and protective factors associated with patterns of violence exposure. We ran K-means iterative cluster analysis to determine patterns of violence exposure and conducted analysis of variance to test whether clusters differed. Data are from 287 Black males ( M = 18.9) who participated in the Black Youth Project–Youth Culture Survey. Participants in the current study self-identified as Black or African American and male, and completed the political participation, health, and demographic portions of the survey questionnaire. We found four clusters of violence exposure that were related to demographic characteristics, maternal closeness, neighborhood condition, and sociopolitical inequity. Our findings highlight the heterogeneity of exposure to violence among young Black males and the individual and environmental risk and protective factors that are related to types and levels of exposure. This examination of quality of violence exposure in the context of available risks and protective factors may help clinicians and researchers improve their intervention efforts.

You Do What You See

African American boys are more likely than same-aged counterparts to live in disadvantaged neighborhoods characterized by exposure to physical violence, lower socioeconomic status, poor parent education, and acts of violence. The current study used structural equation modeling to test the associations between witnessing violence, peer and parent expectations, peer behaviors, self-efficacy to avoid violence, and violent behavior as the outcome. Results suggest that African American boys who witnessed physical violence are more likely to engage in violence themselves. Peer and parent violence expectations, peer violence, and adolescent’s self-efficacy to avoid violence mediate this. These findings suggest potential for prevention of violent behaviors through modification of norms of male African American adolescents at risk for witnessing violence in their daily life.

Social Information Processing Mechanisms and Victimization: A Literature Review

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

Aggression Norms in the Classroom Social Network: Contexts of Aggressive Behavior and Social Preference in Middle Childhood

In a cross-sectional sample of African-American 2nd-4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers' social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children's direct and indirect connections in the classroom. Results of multilevel models indicate that network-based classroom aggression norms moderated relations between children's aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.

Children who are exposed to intimate partner violence: Interviewing mothers to understand its impact on children

Children's victimization related to intimate partner violence (IPV) has damaging effects on their well-being and development. The purpose of this research was to assess the impact of IPV on children's emotional and behavioral problems through their mothers' narratives. A total of 30 Spanish mothers (mean age=41.57 years, SD=8.54 years) were individually interviewed. The results showed that many of the children directly suffered from aggression, and most of them witnessed IPV. As a result of their exposure to violence, children often develop psychological, social, and school problems. Their learning of aggressive behaviors is especially remarkable, and these behaviors are sometimes directed towards their mothers. Thus, women can suffer a twofold victimization: by their partner and by their children. These additional problems contribute to hindering the recovery process of victims. Fortunately, not all children develop problems as a result of exposure to IPV; some of them are capable of mature responses.

Social cognitions, distress, and leadership self-efficacy: associations with aggression for high-risk minority youth

Urban ethnic minority youth are often exposed to high levels of aggression and violence. As such, many aggression intervention programs that have been designed with suburban nonethnic minority youth have been used or slightly adapted in order to try and meet the needs of high-risk urban youth. The current study contributes to the literature base by examining how well a range of social-cognitive, emotional distress and victimization, and prosocial factors are related to youth aggression in a sample of urban youth. This study utilized data gathered from 109 9- to 15-year-old youth (36.7% male; 84.4% African American) and their parents or caregivers. A series of hierarchical multiple regressions were fit predicting youth aggression from social-cognitive variables, victimization and distress, and prosocial variables, controlling for youth gender and age. Each set of variables explained a significant and unique amount of the variance in youth aggressive behavior. The full model including all predictors accounted for 41% of the variance in aggression. Models suggest that youth with stronger beliefs supportive of violence, youth who experience more overt victimization, and youth who experience greater distress in overtly aggressive situations are likely to be more aggressive. In contrast, youth with higher self-esteem and youth who endorse greater leadership efficacy are likely to be less aggressive. Contrary to hypotheses, hostile attributional bias and knowledge of social information processing, experience of relational victimization, distress in relationally aggressive situations, and community engagement were not associated with aggression. Our study is one of the first to address these important questions for low-income, predominately ethnic minority urban youth, and it has clear implications for adapting aggression prevention programs to be culturally sensitive for urban African American youth.

Money and age in schools: Bullying and power imbalances

School bullying continues to be a serious problem around the world. Thus, it seems crucial to clearly identify the risk factors associated with being a victim or a bully. The current study focused in particular on the role that age and socio-economic differences between classmates could play on bullying. Logistic and multilevel analyses were conducted using data from 53,316 5th and 9th grade students from a representative sample of public and private Colombian schools. Higher age and better family socio-economic conditions than classmates were risk factors associated with being a bully, while younger age and poorer socio-economic conditions than classmates were associated with being a victim of bullying. Coming from authoritarian families or violent neighborhoods, and supporting beliefs legitimizing aggression, were also associated with bullying and victimization. Empathy was negatively associated with being a bully, and in some cases positively associated with being a victim. The results highlight the need to take into account possible sources of power imbalances, such as age and socio-economic differences among classmates, when seeking to prevent bullying. In particular, interventions focused on peer group dynamics might contribute to avoid power imbalances or to prevent power imbalances from becoming power abuse. Aggr.

Child-to-parent violence: emotional and behavioral predictors

Child-to-parent violence (CPV) includes acts committed by a child to intentionally cause physical, psychological, or financial pain to a parent. Available data indicate increasing rates of CPV in Spain, which have been attributed to a tendency toward more permissive parenting styles and changes in the power cycles within the families. The primary aim of this study was to assess the predictive role of some behavioral and emotional characteristics of adolescents who perpetrate CPV. A total of 1,072 adolescents (601 girls) filled out measures of CPV, proactive and reactive aggression, depressive symptoms, and substance abuse at Time 1, and measures of CPV 6 months later. The results showed that CPV was predicted by proactive, but not by reactive, aggression. This finding supports an instrumental role for CPV, which should be understood in the context of permissibility and lack of limits within the family. Depression and substance abuse also predicted the increase of CPV over time. Moreover, there were no sex differences in the prevalence of physical CPV, but verbal CPV was more predominant among girls. Although there were sex differences in some of the risk factors for CPV, the predictive model linking these risks to CPV was similar for boys and girls. Findings of this study suggest a psychological profile that combines internalizing problems and an instrumental use of violence in adolescents who perpetrate CPV. These characteristics are important for interventions.

The impact of peer victimization on later maladjustment: mediating and moderating effects of hostile and self-blaming attributions

BACKGROUND

Evidence indicates that being a victim of bullying or peer aggression has negative short- and long-term consequences. In this study, we investigated the mediating and moderating role of two types of attributional mechanisms (hostile and self-blaming attributions) on children's maladjustment (externalizing and internalizing problems).

METHODS

In total, 478 children participated in this longitudinal study from grade 5 to grade 7. Children, parents, and teachers repeatedly completed questionnaires. Peer victimization was assessed through peer reports (T1). Attributions were assessed through self-reports using hypothetical scenarios (T2). Parents and teachers reported on children's maladjustment (T1 and T3).

RESULTS

Peer victimization predicted increases in externalizing and internalizing problems. Hostile attributions partially mediated the impact of victimization on increases in externalizing problems. Self-blame was not associated with peer victimization. However, for children with higher levels of self-blaming attributions, peer victimization was linked more strongly with increases in internalizing problems.

CONCLUSIONS

Results imply that hostile attributions may operate as a potential mechanism through which negative experiences with peers lead to increases in children's aggressive and delinquent behavior, whereas self-blame exacerbates victimization's effects on internalizing problems.

Moderating effects of childhood maltreatment on associations between social information processing and adult aggression

BACKGROUND

Associations between early life maltreatment, social information processing (SIP) and aggression in childhood and adolescence have been widely documented. Few studies have examined the importance of childhood maltreatment independent of SIP in the etiology of adult aggression. Furthermore, moderating effects of childhood maltreatment on the SIP-aggression links have not been explored.

METHOD

Hierarchical, multi-level models were fitted to data from n=2752 twins aged 20-55 years from the PennTwins Cohort. Adult aggression was assessed with the Life History of Aggression questionnaire. Childhood maltreatment was measured using the Childhood Trauma Questionnaire. Two aspects of SIP were examined: hostile attribution biases (HAB); negative emotional responses (NER).

RESULTS

Childhood maltreatment was positively correlated with adult aggression, independently of HAB and NER. In addition, childhood maltreatment moderated the relationships between both aspects of SIP and adult aggression. Specifically, the relationship between NER and aggression was stronger among individuals with higher levels of childhood maltreatment and NER was not associated with aggression for adults who experienced low levels of childhood maltreatment. Moderating effects of childhood maltreatment on the NER-aggression link were supported for total childhood maltreatment, emotional neglect and emotional abuse. In contrast, HAB was more strongly associated with adult aggression at lower levels of emotional abuse and physical neglect.

CONCLUSIONS

The current study provides insight into the mechanisms by which early life experiences influence adult aggression. Our findings suggest that childhood maltreatment may not only lead to increased levels of aggression in adulthood but may also modify the associations between SIP and adult aggression.

Understanding interpersonal trauma in children: why we need a developmentally appropriate trauma diagnosis

Childhood exposure to victimization is prevalent and has been shown to contribute to significant immediate and long-term psychological distress and functional impairment. Children exposed to interpersonal victimization often meet criteria for psychiatric disorders other than posttraumatic stress disorder (PTSD). Therefore, this article summarizes research that suggests directions for broadening current diagnostic conceptualizations for victimized children, focusing on findings regarding victimization, the prevalence of a variety of psychiatric symptoms related to affect and behavior dysregulation, disturbances of consciousness and cognition, alterations in attribution and schema, and interpersonal impairment. A wide range of symptoms is common in victimized children. As a result, in the current psychiatric nosology, multiple comorbid diagnoses are necessary-but not necessarily accurate-to describe many victimized children, potentially leading to both undertreatment and overtreatment. Related findings regarding biological correlates of childhood victimization and the treatment outcome literature are also reviewed. Recommendations for future research aimed at enhancing diagnosis and treatment of victimized children are provided.
