Social cognitive and emotional mediators link violence exposure and parental nurturance to adolescent aggression

Prediction of Youth Violence Perpetration by Parental Nurturing Over Time

Parental nurturing, including maternal and paternal caring and discussing ethics, is likely to predict violence perpetration in the youth negatively. This prediction stands on social bond theory, which specifies that parents and their bonding are crucial to curb violence perpetration. Nevertheless, the prediction is unclear from adolescence to young adulthood. To clarify this, the present study examines the effects over 6 years, using the panel data of the National Longitudinal Study of Adolescent to Adult Health on 3,947 U.S. youths. The examination controlled for prior violence perpetration and, thus, its confounding factors. Results showed that paternal nurturing but not maternal nurturing at Wave 1 and Wave 2 consistently displayed statistically significant inverse effects on violence perpetration at Wave 3. However, the significant effects were very weak. Paternal nurturing was very weakly inversely predictive of youth violence perpetration 6 years later. This conclusion implies that promoting paternal nurturing is slightly but not tremendously helpful to prevent violence perpetration in youth later. Meanwhile, practice can capitalize on the features of paternal bonding to deploy male nurturing and role modeling for such prevention.

Violence against women and its effects on mental health and quality of life: A study of Myanmar migrant workers in Central Thailand

Background

Women migrant workers are vulnerable to violence. Violence against women is a pervasive public health problem, violates women's rights, and may adversely affect women's quality of life (QoL) and mental health. However, few studies have focused on this problem among migrant women workers from Myanmar.

Objective

This study aimed to use structural equation modeling to investigate the effect of violence against migrant women workers from Myanmar on their QoL and mental health.

Methods

This study was a cross-sectional study of 378 migrant women workers from Myanmar in Central Thailand, conducted by multistage sampling. The authors collected the data through a face-to-face structured interview using standard questionnaires and then investigated the effects of violence on QoL and mental health mediated by social support while considering the effects of socioeconomic status on violence.

Results

More than half the women had experienced violence within 12 months (58.7 %). Violence had a direct negative impact on their QoL and a direct positive association with mental health problems. Social support did not mediate these effects but did have a direct positive impact on QoL and a direct negative association with mental health problems. Socioeconomic status was directly affected by violence and had an indirect impact on QoL and mental health mediated by violence.

Conclusion

The study raises awareness about violence's impact on the QoL and mental health of migrant women workers from Myanmar in Thailand. We highlight the urgent need for comprehensive initiatives to provide social support mechanisms and promote socioeconomic empowerment. Collaborative efforts among government, nongovernment organizations, and communities are crucial for ensuring legal protections and safe working conditions, with regular monitoring and evaluation to gauge effectiveness in preventing violence and promoting these women's QoL and mental health.

Social environment risk factors for violence, family context, and trajectories of social-emotional functioning among Latinx adolescents

INTRODUCTION

High social-emotional functioning, including emotion regulation and nonviolent conflict resolution, constitute developmental competencies of adolescence that promote health and well-being. We used prospective longitudinal data from a predominantly Latinx population to understand how family context and social environment risk factors for violence related to patterns of social-emotional functioning during the transition between middle school and high school.

METHODS

We prospectively interviewed 599 8th graders every 6 months for 2 years. We used trajectory models to explore longitudinal patterns of emotion regulation and nonviolent problem solving and multinomial regression to distinguish how these groups were associated with family context, partner and peer gang involvement, and neighborhood social disorder.

RESULTS

Youth reporting lower neighborhood disorder in 8th grade were more likely to be in the high emotion regulation trajectory group. Youth without exposure to gangs through peers and partners in 8th grade were more likely to be in the high nonviolent problem-solving skills trajectory group. Family cohesion was associated with being in the high trajectory groups for both emotional regulation and problem-solving skills.

CONCLUSION

Emotion regulation and nonviolent problem-solving skills had different associations with the social environment risk factors for violence examined, indicating that mechanisms of influence and strategies for intervention may vary. The association between problem-solving skills and exposure to gangs through peers and partners shows that social norms may be important targets of change. Additionally, interventions with parents that build family cohesion during adolescence may buffer environmental exposures that shape adolescents' ability to practice protective social-emotional behaviors.

The Complex Nature of School Violence: Attitudes Toward Aggression, Empathy and Involvement Profiles in Violence

Background

Aggressive behavior in adolescents has become a concern in education, where adapting to and going through high school may generate important behavior problems in adolescents.

Purpose

Analyze the relationships between parental and adolescent attitudes toward aggression and empathy. Identify profiles of direct and indirect involvement in school violence and determine differences between groups with respect to the components of empathy and attitudes toward aggression.

Methods

The sample was comprised of 1287 high school students who were administered the Beliefs about Aggression and Alternatives questionnaire, the Parental Support for Fighting and the Interpersonal Reactivity Index.

Results

The results show that beliefs in favor of the use of aggression in adolescents correlate positively with the perception of strong support from parents for aggression in response to conflict. Similarly, higher levels of support for the use of nonviolent strategies are positively related to the perception of strong support from parents. The relationships established with the components of empathy analyzed, both cognitive and emotional, were negatively correlated with favorable attitudes toward aggression. Results concerning the groups directly involved indicated that there were significant differences in the components of empathy between the groups. Furthermore, the multivariate analysis applied to the direct involvement groups showed significant differences between the groups in taking perspective. Between-group differences in empathic concern were also statistically significant for the group of active observers.

Conclusion

Taking perspective and empathic concern are moderating variables both for observers and victims and their parents in situations of violence.

Parental Psychological Control and Children's Relational Aggression: Examining the Roles of Gender and Normative Beliefs about Relational Aggression

Drawing on the information processing model for the development of aggression, children's acquisition of aggressive responses could be associated with parenting that communicated norms favoring aggression. Extending this view, the present study examined the mediating role of children's normative beliefs about relational aggression (NBRA) on the association between psychologically controlling parenting and children's relational aggression (RA), and further explored whether this possible indirect effect would be contingent on the child's gender. 341 upper elementary school students (174 boys and 166 girls) reported perceived paternal psychological control (PPC) and maternal psychological control (MPC) during their fifth-grade fall semester, rated their NBRA during their sixth-grade fall semester, and assessed RA through a peer-nomination procedure during their sixth-grade spring semester. Results demonstrated that the indirect effects of perceived PPC and MPC on children's RA via their NBRA were both significant among the entire sample. However, by means of conditional process analysis, we found that whereas perceived PPC positively predicted boys' and girls' NBRA, perceived MPC positively predicted boys' but not girls' NBRA. In addition, children's NBRA was only positively predictive of RA for girls. As such, the indirect effect was exclusively significant for perceived PPC among girls.

Emotional Desensitization to Violence Contributes to Adolescents' Violent Behavior

Many adolescents are exposed to violence in their schools, communities and homes. Exposure to violence at high levels or across multiple contexts has been linked with emotional desensitization, indicated by low levels of internalizing symptoms. However, the long-term consequences of such desensitization are unknown. This study examined emotional desensitization to violence, together with externalizing problems, as mediators of the relationship between exposure to violence in pre-adolescence and violent behavior in late adolescence. A community sample of youth (N = 704; 48% female; 76% African American, 22% Caucasian) reported on their exposure to violence in multiple settings at ages 11, 13 and 18. Internalizing and externalizing problems were assessed at ages 11 and 13; violent behavior was measured at age 18. Structural Equation Modeling showed that exposure to high levels of violence at age 11 was associated with lower levels of internalizing problems (quadratic effect) at age 13, as was exposure to violence across multiple contexts (linear effect). In turn, fewer internalizing problems and more externalizing problems at age 13 predicted more violent behavior at age 18. The results suggest that emotional desensitization to violence in early adolescence contributes to serious violence in late adolescence.

Multiple Forms and Settings of Exposure to Violence and Values: Unique and Interactive Relationships With Antisocial Behavior in Adolescence

The general purpose of this study was to investigate the relationships between multiple forms and settings of exposure to violence (ETV) as well as personal values and antisocial behavior (ASB) in adolescence. The association of ETV as witness or victim in different contexts (family, school, or neighborhood) and the association of the selected values of power, universalism, and conformity with ASB were analyzed. In addition, the role of ETV in moderating the relationship between values and ASB was tested. A total of 369 adolescents participated in the study. Hierarchical multiple regression analysis was performed. Results revealed that ASB was independently affected by exposure to family violence as a victim, exposure to school violence as a witness, exposure to neighborhood violence as a witness, and by all three selected values. The associations of ASB with universalism and conformity were negative. Conversely, the association of ASB with power was positive. One interaction had statistically significant effects. Results revealed that exposure to school violence as a witness moderates the relationship between universalism and ASB. The results highlight a high percentage of explained variance by ETV and values on ASB and suggest the importance of adopting a socio-ecological framework in interpreting adolescent behavior.

Neurochemical correlates of accumbal dopamine D2 and amygdaloid 5-HT 1B receptor densities on observational learning of aggression

Social learning theory postulates that individuals learn to engage in aggressive behavior through observing an aggressive social model. Prior studies have shown that repeatedly observing aggression, also called "chronic passive exposure to aggression," changes accumbal dopamine D2 receptor (D2R) and amygdaloid 5-HT1B receptor (5-HT1BR) densities in observers. But, the association between these outcomes remains unknown. Thus, in our study, we used a rat paradigm to comprehensively examine the linkage between aggression, D2R density in the nucleus accumbens core (AcbC) and shell (AcbSh), and 5-HT1BR density in the medial (MeA), basomedial (BMA), and basolateral (BLA) amygdala following chronic passive exposure to aggression. Male Sprague-Dawley rats (N = 72) were passively exposed to either aggression or nonaggression acutely (1 day) or chronically (23 days). When observer rats were exposed to aggression chronically, they showed increased aggressive behavior and reduced D2R density in bilateral AcbSh. On the other hand, exposure to aggression, regardless of exposure length, increased the 5-HT1BR density in bilateral BLA. Finally, low D2R in the AcbSh significantly interacted with high 5-HT1BR density in the BLA to predict high levels of aggression in observer rats. Our results advance our understanding of the neurobiological mechanisms in the observational learning of aggression, highlighting that dopamine-serotonin interaction, or AcbSh-BLA interaction, may contribute to a risk factor for aggression in observers who chronically witness aggressive interactions.

Emotional and physiological desensitization to real-life and movie violence

Youth are exposed to large amounts of violence in real life and media, which may lead to desensitization. Given evidence of curvilinear associations between exposure to violence and emotional distress, we examined linear and curvilinear associations of exposure to real-life and movie violence with PTSD symptoms, empathy, and physiological arousal, as well emotional and physiological reactivity to movie violence. College students (N = 209; mean age = 18.74) reported on their exposure to real-life and televised violence, PTSD symptoms, and empathy. Then, students were randomly assigned to view a series of violent or nonviolent high-action movie scenes, providing ratings of emotional distress after each clip. Blood pressure was measured at rest and during video viewing. Results showed that with increasing exposure to real-life violence, youth reported more PTSD symptoms and greater identification with fictional characters. Cognitive and emotional empathy increased from low to medium levels of exposure to violence, but declined at higher levels. For males, exposure to higher levels of real-life violence was associated with diminishing (vs. increasing) emotional distress when viewing violent videos. Exposure to televised violence was generally unrelated to emotional functioning. However, those with medium levels of exposure to TV/movie violence experienced lower elevations of blood pressure when viewing violent videos compared to those with low exposure, and those with higher levels of exposure evidenced rapid increase in blood pressure that quickly declined over time. The results point to diminished empathy and reduced emotional reactivity to violence as key aspects of desensitization to real-life violence, and more limited evidence of physiological desensitization to movie violence among those exposed to high levels of televised violence.

Peripuberty stress leads to abnormal aggression, altered amygdala and orbitofrontal reactivity and increased prefrontal MAOA gene expression

Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression induced by peripubertal exposure to stress with face, construct and predictive validity. We show that male rats submitted to fear-induction experiences during the peripubertal period exhibit high and sustained rates of increased aggression at adulthood, even against unthreatening individuals, and increased testosterone/corticosterone ratio. They also exhibit hyperactivity in the amygdala under both basal conditions (evaluated by 2-deoxy-glucose autoradiography) and after a resident-intruder (RI) test (evaluated by c-Fos immunohistochemistry), and hypoactivation of the medial orbitofrontal (MO) cortex after the social challenge. Alterations in the connectivity between the orbitofrontal cortex and the amygdala were linked to the aggressive phenotype. Increased and sustained expression levels of the monoamine oxidase A (MAOA) gene were found in the prefrontal cortex but not in the amygdala of peripubertally stressed animals. They were accompanied by increased activatory acetylation of histone H3, but not H4, at the promoter of the MAOA gene. Treatment with an MAOA inhibitor during adulthood reversed the peripuberty stress-induced antisocial behaviors. Beyond the characterization and validation of the model, we present novel data highlighting changes in the serotonergic system in the prefrontal cortex-and pointing at epigenetic control of the MAOA gene-in the establishment of the link between peripubertal stress and later pathological aggression. Our data emphasize the impact of biological factors triggered by peripubertal adverse experiences on the emergence of violent behaviors.
