Links between stressful life events and proactive and reactive functions of aggression

Examining the Moderating Role of Parental Stress in the Relationship between Parental Beliefs on Corporal Punishment and Its Utilization as a Behavior Correction Strategy among Colombian Parents

Understanding beliefs about corporal punishment is crucial, as evidence suggests that positive beliefs in its effectiveness predict its use. High parental stress, especially in those valuing corporal punishment, increases the potential for child abuse. Factors such as having many children or low education and socioeconomic status contribute to parental tensions, leading to the use of corporal punishment for behavior correction. We posit that the accumulation of such variables results in heightened stress levels. Our focus aimed to determine the moderating role of stress levels among parental beliefs about corporal punishment and its reported use through quantitative research. In our study, 853 Colombian parents of low, middle, and high socioeconomic status, and from four different regions of Colombia, with children aged 0 to 17 participated. They provided information about their beliefs on corporal punishment, using the Beliefs and Punishment Scale. Correlations indicated that older parents with better socioeconomic status were less inclined to believe that strictness improves children. Regressions suggested that increased belief in corporal punishment modifying behavior, along with higher parental stress, increases corporal punishment use. Moderation models highlighted that when more stressors were present, corporal punishment was used due to stress rather than parental beliefs. Ultimately, stress emerged as a crucial factor influencing corporal punishment use among Colombian parents.

Does sports participation affect the mediating role of impulsivity in the association between adverse childhood experiences and aggression?

Introduction

Adverse childhood experiences (ACEs) and self-reported aggression have often been associated, however, the mediating and moderating mechanisms underlying this association are not fully understood. In addition, less is known about potential factors that could serve as protection against the development of aggressive behavior. In this study, we investigated a moderated mediation model of sports participation and five impulsivity traits including positive and negative urgency, sensation seeking, and lack of premeditation and perseverance, in the association between ACEs and two forms of aggression.

Methods and results

The sample comprised 651 (68.5% females) individuals from a Dutch community ranging in age from 18 to 82 years (M = 34.08). Contrary to our expectations, sports participation did not affect the associations of ACEs, the five impulsivity traits, and reactive and proactive aggression, except the association between ACEs and lack of premeditation. Specifically, the detrimental effect of ACEs on the propensity to act without thinking, increases among individuals with lower levels of sports participation. In addition, it was also found that sports participation directly contributed to higher levels of sensation seeking. Finally, after controlling for sociodemographic variables, the positive association between ACEs and reactive aggression was significantly mediated by negative urgency, lack of perseverance, and lack of premeditation, while the positive association between ACEs and proactive aggression was significantly mediated by lack of premeditation and positive urgency.

Conclusion

The findings of this study add to the body of knowledge about the role of sports participation and impulsivity traits in the development of both forms of aggression, however, replication studies among multiple populations are needed before firm conclusions can be drawn.

Stressful life events: Typology of aggression and mistreatment in male perpetrators of gender-based violence

The objective of this study was to analyze groups based on the stressful life events suffered and to know the relationship of these profiles with the type of abuse exercised against women in the couple. A sample of 118 heterosexual men who perpetrated gender-based violence was used, with a mean age of 40.46 years (SD = 11.14). The results show that those who suffered a greater number of adverse experiences abused their partners more frequently and with a more aggravated character. In addition, knowing typologies based on previous stressful life events could favor specific interventions in the elimination of the normalization of violence as a maladaptive relational strategy. It is necessary to continue investigating the characteristics of men who exercise gender-based violence, as well as to analyze previous exposure to violence in the family of origin due to the influence it exerts on subsequent abuse.

The centrality of cognition and coping styles in driving aggressive responses

OBJECTIVE

Despite the presence of theoretical frameworks explaining aggression, they still require refinement in the form of a specification of mechanisms that facilitate such behaviour.

METHOD

Study 1 recruited participants (N = 31) from the general population (N = 20) and from a forensic hospital (N = 11). It was expected that aggression supportive cognitions and stress would be positively associated with aggressive behaviour. An experimental paradigm was used to induce stress and participants were subsequently given the opportunity to aggress. Study 2 was based on self-report questionnaires in community sample (N = 462). It was expected that aggressive behaviour and traits would be associated with experienced stress, hostile attributions, coping styles, and attitudes to violence. Specifically, that criminal attitudes to violence will mediate the effect of hostile attribution on aggression, while coping styles will mediate the effect of perceived stress.

RESULTS

An Implicit Theory "I am the law" was found to be associated with aggression. Furthermore, elevated skin conductance, but not changes in the heart rate, during the stress task was positively associated with aggression, and only among patients. Structural Equation Model confirmed the mediating role of criminal attitudes to violence and of maladaptive coping style for aggressive behaviour.

CONCLUSION

Aggression-supportive cognitions and maladaptive coping style are specific mechanisms through which external demands or subjective perception of a situation can result in aggressive behaviour.

Prevalence and determinants of aggressive behavior among adults with problematic substance use in Northwest Ethiopia: a cross-sectional survey

BACKGROUND

The recent WHO data reported that a high treatment gap for behavioral illnesses (70%) in low- and- middle-income countries and the mortality rate of aggressive behavior reaches up to 32.1 per 100,000 populations in the region. However, the magnitude of aggressive behavior is not well stated in resource-limited settings. Therefore, the aim of this study was to assess the prevalence and determinant factors of aggressive behavior among adults with problematic substance use in northwest Ethiopia.

METHODS

A community-based cross-sectional study was employed from January to March 2019. A multi-stage cluster sampling method was used to screen a total of 4028 adults for problematic substance use by using the Cutdown, Annoyed, Guilty, and Eye-opener questionnaire (CAGE AID). Finally, 838 participants were positive for problematic substance use and interviewed for aggressive behavior using a modified overt aggression scale. Multiple logistic regression analysis was used to show the adjusted odds ratios (AOR) and p-value < 0.05 considered statistically significant. A multilevel binary logistic regressions model was employed for the hierarchical structure of two-level data for the individual and woreda/district levels.

RESULTS

The prevalence of aggressive behavior was found to be 37.9% (301/795, 95% CI: 34.5, 41.3). Stressful life events (AOR = 2.209, 95 CI; 1.423, 3.429), family history of mental illness (AOR = 4.038, 95 CI; 2.046, 7.971), comorbid physical illness (AOR = 2.01, 95 CI; 1.332, 3.032) and depressive symptoms (AOR = 2.342, 95 CI; 1.686, 3.253) were associated with aggressive behavior among individual with problem substance use.

CONCLUSION

Aggressive behavior was found to be high among problematic substance uses. An individual with problematic substance use is recommended to be screened by health extension workers for aggressive behavior at the community level.

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.

Association between schizoid tendencies and aggressive behaviors: mediating and moderating influences in childhood trauma and life events among Chinese adolescents

BACKGROUND

This study investigated an association between schizoid tendencies and aggressive behaviors in Chinese adolescents, and explored the underlying mechanism.

METHODS

The data of 3094 adolescents aged 12 to 16 years were collected from an epidemiological survey in China. All the subjects or their parents completed the Achenbach's Child Behavior Checklist, the Childhood Trauma Questionnaire-Short Form, and the Adolescent Self-rating Life Event Checklist (ASLEC).

RESULTS

Relative to the non-schizoid group, adolescents with schizoid tendencies (male or female) showed significantly higher scores for aggressive behaviors, emotional abuse, and ASLEC. Regarding females only, those with schizoid tendencies had significantly higher (lower) scores for physical abuse and emotional neglect (physical neglect). The aggressive behaviors score was predicted by scores for schizoid tendencies (β_male = 0.620, β_female = 0.638, both P < 0.001) and ASLEC (β_male = 0.125, β_female = 0.061, both P < 0.01), and by childhood trauma score (males: emotional neglect [β = 0.045, P = 0.021]; females: emotional abuse and sexual abuse [β = 0.118 and - 0.062, both P < 0.01]). The ASLEC and childhood trauma scores mediated the association between scores for schizoid tendencies and aggressive behaviors, specifically, emotional neglect (emotional abuse and sexual abuse) in males (females). In females, the interaction between scores for childhood trauma and ASLEC affected the aggressive behaviors score (P = 0.023).

CONCLUSIONS

Schizoid tendencies are associated with aggressive behaviors among Chinese adolescents. Recent life events and childhood trauma mediated an association between schizoid tendencies and aggressive behaviors. The interaction between childhood trauma and recent life events affected aggressive behaviors in females. Aggressive behaviors in adolescents may be ameliorated by reducing childhood trauma and life events.

The Role of Psychopathic Traits in Explaining Associations Between Childhood Traumatic Experiences and Aggression

The present study reports on a preregistered investigation of the potential mediating role of the triarchic psychopathy components Boldness, Meanness, and Disinhibition for associations between childhood traumatic experiences (CTE) and aggression. Three nonclinical samples (total N = 1,729; 1,176 women, 68.02%) completed self-report instruments of CTE, triarchic psychopathy traits, reactive and proactive aggression (Samples 1 and 2), and general aggression (Sample 3). Cross-sectional path analyses revealed that both Meanness and Disinhibition consistently mediated associations between CTE and aggression. These indirect effects were consistent across gender, even though the direct effect of Meanness on proactive aggression was stronger in men than in women (Samples 1 and 2). Finally, Boldness had weak negative associations with childhood traumatic experiences in all three samples, but no direct association with aggression. Taken together, these correlational findings suggest potential developmental mechanisms linking early traumatic experiences to adult aggression through elevated levels of psychopathic traits.

Exposure to Gun Violence: Associations with Anxiety, Depressive Symptoms, and Aggression among Male Juvenile Offenders

Objective: To examine whether at-risk male youth experience increases in anxiety, depressive symptoms, and aggression during years when they are exposed to gun violence, adjusting for relevant covariates.Method: Participants were 1,216 male, justice-involved adolescents who were recently arrested for the first time for a moderate offense. They were interviewed 9 times over 5 years. Fixed effects (within-individual) regression models were used to estimate concurrent associations between exposure to gun violence and three outcomes: depressive symptoms, anxiety symptoms, and aggression (both overall and separately for proactive and reactive aggression). The reverse direction (anxiety, depressive symptoms, and aggression predicting gun violence exposure) was also modeled.Results: After controlling for covariates, exposure to gun violence was significantly associated with increases in reactive aggression and, to a lesser extent, increases in proactive aggression. In addition, gun violence exposure was associated with increased anxiety but not depressive symptoms. We found no support for the reverse direction.Conclusions: At-risk males experienced significant increases in anxiety and aggression (particularly reactive aggression) during years when they are exposed to gun violence, even after accounting for several potential confounding factors. The greater impact on reactive aggression suggests that exposure to gun violence may affect self-regulation and/or social information processing. The analyses shed light on the less-visible damage wrought by gun violence and underscore the importance of mental health screening and treatment for youth who have been exposed to violence - especially gun violence - both to assist individual youths and to disrupt cycles of violence.

Pathways From Early Family Violence to Adolescent Reactive Aggression and Violence Victimization

PURPOSE

The current study examined how early childhood (EC) family violence and risk (i.e., maternal aggression, sibling aggression, environmental risk) predicted early adolescent (EA) reactive physical and relational aggression and violence victimization through middle childhood (MC) parenting (i.e., guilt induction, power assertive discipline).

METHOD

Mother-infant dyads (N = 216; 72% African American) were recruited as part of a larger longitudinal study on prenatal cocaine and other substance exposure. Observations, interviews, and maternal and child self-report measures were collected from dyads in early childhood (1 to 36 months), middle childhood (84 months), and early adolescence (12 to 15 years).

RESULTS

A cascading path model was specified where current variables were regressed on variables from the preceding time point. Primary results showed that environmental risk and EC child physical aggression predicted higher levels of MC caregiver power assertive discipline, which subsequently predicted lower levels of EA reactive relational aggression. Maternal substance use in pregnancy and the child's continuous placement with biological caregivers predicted higher levels of reactive physical aggression in EA. Finally, MC physical aggression and EA reactive relational aggression predicted higher levels of EA violence victimization.

CONCLUSION

There were a series of direct paths from early childhood family violence and demographic factors to reactive aggression and violence victimization. The current study underscores the importance of evaluating multiple facets of family violence and risk when evaluating aggressive behavior and victimization.
