There is convincing evidence that demonstrates traumatic stress and aggressive behavior are highly related among adolescents. The evidence is less clear regarding the direction of this relation. The purpose of this study was to examine the reciprocal longitudinal relations between physical aggression and traumatic stress among a predominantly African American sample of middle school students. Support was found for traumatic stress predicting increased levels of physical aggression across the winter to the spring of the sixth grade for boys and across all waves from the fall of the seventh grade to the fall of the eighth grade for both boys and girls. Conversely, physical aggression during the winter of the sixth grade predicted a decrease in traumatic stress in the spring of the sixth grade for both boys and girls. These findings suggest that interventions may need to incorporate skills that are aligned with trauma-informed care practices in order to reduce traumatic stress and physical aggression among adolescents.

Impulsivity, venturesomeness, and pride variables were examined as potential moderators of the associations between childhood trauma and physical aggression, alcohol use and physical aggression, and drug use and physical aggression. Participants (n = 457) were college students recruited from a university in the Southeast. It was hypothesized that childhood trauma, alcohol use, and drug use would be associated with increased scores of physical aggression. In addition, it was hypothesized that impulsivity, venturesomeness, authentic pride, and hubristic pride would moderate these relationships. Linear, multivariate hierarchical regression analyses were used to examine these variables as potential moderators. Hypotheses concerning hubristic pride as a moderator of the relationship between alcohol use and physical aggression as well as the relationship between drug use and physical aggression were supported. In addition, the hypothesis concerning authentic pride as a moderator of the relationship between alcohol use and physical aggression was supported albeit in the opposite direction than predicted. Hypotheses concerning the moderating roles of impulsivity and venturesomeness were not supported. Findings support the idea that the deleterious psychological effects of substance use can be compounded by personality factors such as authentic and hubristic pride. The discussion encompasses why interventions should target attributions and cognitions and why simply encouraging someone to have a more “healthy pride” is likely to be ineffective at reducing physical aggression in the context of drug use and alcohol use.

This study seeks to explicate the impact of sex and gender in the relationships among attachment, romantic jealousy, and aggression. Attachment theory (e.g., Bowlby, 1969) posits that unique attachment styles develop based on experiences with primary caregiver(s). These attachment styles (e.g., secure, preoccupied, dismissing, and fearful) are enduring, and come to define attachment in adult romantic relationships (Bartholomew & Horowitz, 1992; Hazan & Shaver, 1987). Attachment theory argues that differences in jealousy in adult romantic relationships are a function of attachment style (e.g., Guerrero, 1998). Similarly, attachment frameworks explain aggression (e.g., physical, verbal, and indirect/social/relational) as a function of attachment style, suggesting that these constructs (both aggression and jealousy) are borne from early childhood experiences. Theories that posit sex and gender differences, however, argue that aggression and jealousy are rooted in biological (i.e., sex-linked), evolutionary (i.e., adaptive), and social (i.e., learned) explanations of how men and women differ.This study aims to examine these theoretical perspectives in an attempt to further understand how differences between the two (attachment and sex/gender theories) can be explained. Results from this study indicate that sex and gender are unique, and do have differential effects on the relationships among attachment, aggression, and romantic jealousy in romantic relationships. Though the moderating effects of sex and gender are not always strong, findings from this study suggest that biology, evolution, and socialization likely interact and influence variability in attachment, aggression, and romantic jealousy.

This study provided the first direct test of the cognitive underpinnings of the attention-allocation model and attempted to replicate and extend past behavioral findings for this model as an explanation for alcohol-related aggression. Men were randomly assigned to a beverage (Alcohol, No-Alcohol Control) and a distraction (Moderate Distraction, No Distraction) condition. All men were provoked by a male confederate and completed a dot probe task and a laboratory aggression task without distraction or while presented with a moderate distraction task. Results indicated that intoxicated men whose attention was distracted displayed significantly lower levels of aggression bias and enacted significantly less physical aggression than intoxicated men whose attention was not distracted. However, aggression bias did not account for the lower levels of alcohol-related aggression in the distraction, relative to the no-distraction, condition. Discussion focused on how these data inform intervention programming for alcohol-related aggression.

Thesis (MSc)--Stellenbosch University, 2001. / AFRIKAANSE OPSOMMING: Die primêre doel van die huidige studie was om kruis-kulturele verskille ten opsigte van direkte en indirekte aggressie tussen Xhosa, Zulu, Kleurling en Blanke Suid-Afrikaanse studente te bestudeer. 'n Totaal van 832 studente het die Richardson Conflict Response Questionnaire (RCRQ), 'n vraelys wat direkte en indirekte aggressie meet, voltooi. Die Kleurling-deelnemers het beduidend-hoër vlakke van direkte aggressie gerapporteer as enige van die ander groepe. Die Zulu-deelnemers het beduidend-hoër vlakke van indirekte aggressie as beide die Xhosa- of Kleurling-deelnemers gerapporteer. Geen beduidende geslagsverskille kon vasgestel word nie. Daar is tot die slotsom gekom dat kultuur 'n groter bepaler van verskille ten opsigte van aggressiewe gedrag was as geslag van die deelnemers. Daar word vertrou dat die resultate van die huidige studie 'n bydra sal maak tot die effektiewe bestuur van aggressie in Suid-Afrika, asook tot die bevordering van internasionale begrip vir die kulturele diversiteit van die land. / ENGLISH ABSTRACT : The primary aim of the present study was to examine cross-cultural differences in direct and indirect aggression between Xhosa, Zulu, Coloured and White South African students. A total of 832 students completed the Richardson Conflict Response Questionnaire (RCRQ), a measure of direct and indirect aggression. The Coloured participants reported using significantly higher levels of direct aggression than any of the other cultural groups involved. The Zulu participants reported using significantly more indirect aggression than their Xhosa or Coloured counterparts. No significant gender differences could be established. It was concluded that culture was more predictive of differences in aggressive behaviour than was sex of the participants. It is hoped that these results may contribute towards the effective management of aggression in South Africa and assist in promoting international understanding of the cultural diversity in this country.

High prevalence rates exist for physical (i.e., threatened or actual physical force) and relational (i.e., actions meant to harm another’s social relationships) aggression within early adolescence, and these behaviors lead to detrimental social, physical, and mental health outcomes. Thus, there is a need to identify risk and protective processes related to these subtypes of aggression, especially those that can inform violence prevention efforts. Prior studies including early adolescents have shown emotion dysregulation to be a risk factor for aggression. However, few studies have incorporated the emotional competence process of poor emotional awareness, which may be a risk factor for emotion dysregulation and, in turn, for aggression. Furthermore, little research has assessed relations between subtypes of emotion dysregulation (i.e., anger and sadness) and physical and relational aggression. The current study examined longitudinal relations between poor emotional awareness and these subtypes of emotion dysregulation and aggression, as well as concurrent pathways between the emotion dysregulation and aggression variables. Exploratory tests for gender differences were also conducted. Rating scales were collected from 528 sixth graders (51% girls, 49% boys; missing data n = 8) and their teachers over a six month period in the fall and spring of the school year. Across the full sample, 65% of students identified as African-American, 19% European-American, 2%, Hispanic Latino, 11% Multiracial, and 3% as “Other”(missing data n = 8). Results indicated no significant differences by gender in the strength of relations between study variables. Poor emotional awareness was not directly related to changes in subsequent frequency of physical or relational aggression. However, poor emotional awareness at Time 1 was associated with later rates of anger and sadness dysregulation. Furthermore, an indirect effect was found for poor emotional awareness on both physical and relational aggression via anger dysregulation, and this was true for student- and teacher-rated outcomes. Sadness dysregulation showed a negative concurrent association with teacher-rated physical aggression; and there was an indirect effect of poor emotional awareness on teacher-rated physical aggression via sadness dysregulation. Study findings have important implications for theoretical treatises, youth violence prevention programs, and future directions for research, which are all discussed.

There is convincing support for the link between family composition and adolescents’ problem behaviors. What is less clear is the extent to which these relations exist for African-American adolescents. Previous studies have demonstrated that this relation varies by gender. However, there is limited evidence to suggest the potential moderating influence of adult support. The purpose of this study was to examine the influence of family composition on adolescents’ physical aggression, delinquency, and substance use. The study comes from secondary analyses of a larger study that evaluated the effectiveness of a violence prevention program. The current study included 1,116 African-American middle school students from an urban setting who endorsed living with their biological mother and considered her to be their parent. Results indicated that among adolescents who identified their nonresidential biological father as their parent, those in stepfather families reported lower levels of delinquency than those in single-mother families. Support was not found for similar differences in self-report of delinquency and substance use, and teacher-report of adolescents’ physical aggression. No other differences in family composition were found for adolescent problem behavior. Support was also not found for the moderating roles of gender or adult support. However, self-report of delinquency and substance use, and teacher-report of physical aggression were negatively related to adult support. This was not the case for self-report of physical aggression. These findings suggest that interventions may need to provide additional resources that would help both parents and adolescents within single-parent families.

This study explored the effects of a gender-based violence prevention program called Owning Up on a group of middle school students in Tampa, Florida. The majority of participants were African-American at-risk youth who voluntarily participated in the intervention. This study is novel in that it is one of the first to empirically validate curricula that addresses an array of aggressive behaviors. A mixed methods design was used to gain insight into significant changes over time, as well as treatment integrity throughout the implementation. Findings from the study found females to be more aggressive than males on all forms of aggression across time. Additionally, results suggest that minimal gains were found between pre- and post-test administrations indicating that the intervention with this particular group may have not been effective. Cultural fit, systems-level issues, and problem-solving tactics are discussed to explain the findings.
