You Have to Hit Some People! Measurement and Criminogenic Nature of Violent Sentiments in Australia

Criminal sentiments are the highest risk factor for recidivism. Although criminal sentiments have been reliably measured, there are few scales measuring violent sentiments. The aim of this study was to report on three studies exploring the theory and psychometrics of a new Justification for Violence Scale (JFV). The JFV items have high ecological validity in that they were drawn from in-depth interviews with violent men. Psychometric analysis showed that the JFV was unifactorial with high criterion-related validity differentiating three distinct groups (sample N = 530): male offenders, men and women from the community, and university undergraduates. In a further study of 250 community adults, high correlations with self-reported physical aggression and violent fantasies, and negative correlations with social desirability supported the JFV's convergent and discriminant validity. The JFV can be used by researchers or clinicians as a single measure or the items can be inserted into the Criminal Sentiments Scale to enhance the measurement of violent and criminal attitudes and beliefs.

Prediction of sexual trauma via disruption of sex–aggression associations

A variant of the Implicit Association Test focusing on the association of sexual and aggressive themes was administered to 90 college students (61 women) and correlated with a series of variables based on participant history of sexually traumatic events. A history of sexual abuse was correlated with increased difficulties in processing sexual and aggressive concepts simultaneously. Furthermore, this relationship remained significant after controlling for general level of emotional distress, and even after controlling for self-reported aggressiveness and positive feelings towards sex. The findings provide grounds for further exploration of deficits in associations between sexual and aggressive concepts as a possible indicator of the cognitive effects of sexual abuse.

Examining Associations Between Narcissism, Behavior Problems, and Anxiety in Non-Referred Adolescents

The present study examined associations between narcissism (total, adaptive, and maladaptive), self-esteem, and externalizing and internalizing problems in 157 non- referred adolescents (aged 14 to 18). Consistent with previous research, narcissism was positively associated with self-reported delinquency, overt aggression, and relational aggression. Maladaptive narcissism showed unique positive associations with aggression and delinquency variables, while adaptive narcissism showed unique negative associations with anxiety symptoms. In general, self-esteem was negatively related to internalizing and externalizing problems. An interaction effect was observed for self-esteem and narcissism in predicting overt aggression. Specifically, at high levels of self-esteem narcissism was significantly associated with overt aggression, whereas it was not at low levels of self- esteem. The current results add to the growing body of research on the role of narcissism in the development of adjustment problems in youth.

Defending girlfriends, buddies and oneself: Injunctive norms and male barroom aggression

Objective Research has demonstrated that young adults tend to overestimate their peers' approval of risky behaviors (i.e., injunctive norms) and that perceived peer approval is associated with actual behavior; however, no empirical studies have assessed injunctive norms in relation to male barroom aggression. The objectives of the present study were to compare young men's own approval of male barroom aggression with their perceptions of approval by male and female peers and to determine the extent that perceived peer approval of male barroom aggression was associated with self-reported physical aggression at a bar, controlling for own approval and heavy episodic drinking. Method 525 young adult male university and community college students who reported drinking and going to a bar, club or pub rated their own approval and perceptions of peers' approval of bar aggression on items reflecting four domains of approval: (1) general approval, (2) defend self, (3) defend friend and (4) protect girlfriend. Results For all four domains, participants attributed greater approval to male peers than to themselves. Aggression was positively associated with own approval for all domains and with perceived male peer approval for general approval, defend self and defend friend, controlling for heavy episodic drinking and own approval of aggression. Perceived approval by female peers was not associated with increased likelihood of aggression. Conclusion The findings suggest that both perceived male peer approval and personal approval are factors associated with male barroom aggression and that addressing approval of barroom aggression is a critical direction for prevention programming.

Self-report and laboratory measures of impulsivity in patients with schizophrenia or schizoaffective disorder and healthy controls

This study examined self-reported impulsivity and aggression and performance on the stop-signal task in patients with schizophrenia or schizoaffective disorder and healthy volunteers. Compared to controls, patients had higher scores on interview and questionnaire measures of impulsivity and aggression and showed increased stop-signal reaction time and greater response variability. These findings are consistent with a specific impairment in response inhibition in schizophrenia.

The neurocognition of conduct disorder behaviors: specificity to physical aggression and theft after controlling for ADHD symptoms

There is growing evidence that among the different conduct disorder (CD) behaviors, physical aggression, but not theft, links to low neurocognitive abilities. Specifically, physical aggression has consistently been found to be negatively related to neurocognitive abilities, whereas theft has been shown to be either positively or not related to neurocognition. The specificity of these links needs further examination because attention deficit hyperactivity disorder (ADHD) links to both physical aggression and neurocognitive variation. The development of self-reported physical aggression and theft, from age 11 to 17 years, was studied in a prospective at-risk male cohort via a dual process latent growth curve model. Seven neurocognitive tests at age 20 were regressed on the growth parameters of physical aggression and theft. The links between neurocognition and the growth parameters of physical aggression and theft were adjusted for ADHD symptoms at ages 11 and 15 (parent, child and teacher reports). Results indicated that verbal abilities were negatively related to physical aggression while they were positively associated with theft. However, inductive reasoning was negatively associated with increases in theft across adolescence. Symptoms of ADHD accounted for part of the neurocognitive test links with physical aggression but did not account for the associations with theft. These differences emphasize the importance of examining specific CD behaviors to better understand their neurodevelopmental mechanisms. They also suggest that youth who engage in different levels of physical aggression or theft behaviors may require different preventive and corrective interventions.

Neural Correlates of Affect Processing and Aggression in Methamphetamine Dependence

Methamphetamine abuse is associated with high rates of aggression but few studies have addressed the contributing neurobiological factors. To quantify aggression, investigate function in the amygdala and prefrontal cortex, and assess relationships between brain function and behavior in methamphetamine-dependent individuals. In a case-control study, aggression and brain activation were compared between methamphetamine-dependent and control participants. Participants were recruited from the general community to an academic research center. Thirty-nine methamphetamine-dependent volunteers (16 women) who were abstinent for 7 to 10 days and 37 drug-free control volunteers (18 women) participated in the study; subsets completed self-report and behavioral measures. Functional magnetic resonance imaging (fMRI) was performed on 25 methamphetamine-dependent and 23 control participants. We measured self-reported and perpetrated aggression and self-reported alexithymia. Brain activation was assessed using fMRI during visual processing of facial affect (affect matching) and symbolic processing (affect labeling), the latter representing an incidental form of emotion regulation. Methamphetamine-dependent participants self-reported more aggression and alexithymia than control participants and escalated perpetrated aggression more following provocation. Alexithymia scores correlated with measures of aggression. During affect matching, fMRI showed no differences between groups in amygdala activation but found lower activation in methamphetamine-dependent than control participants in the bilateral ventral inferior frontal gyrus. During affect labeling, participants recruited the dorsal inferior frontal gyrus and exhibited decreased amygdala activity, consistent with successful emotion regulation; there was no group difference in this effect. The magnitude of decrease in amygdala activity during affect labeling correlated inversely with self-reported aggression in control participants and perpetrated aggression in all participants. Ventral inferior frontal gyrus activation correlated inversely with alexithymia in control participants. Contrary to the hypotheses, methamphetamine-dependent individuals may successfully regulate emotions through incidental means (affect labeling). Instead, low ventral inferior frontal gyrus activity may contribute to heightened aggression by limiting emotional insight.

The Latent Structure of Youth Responses to Peer Provocation

This study examined whether the three categories often applied to children’s behavior—aggressive, avoidant, and assertive—actually capture the structure of a naturalistic sample of youth behavior coded at a more micro level. A sample of lower-income youth (N = 392; M age = 12.69, SD = 0.95) completed a new multiple-choice measure asking them to select responses to scenarios depicting physical, verbal, and relational provocation by a peer. Youth responses to the vignettes showed the expected associations with self-reported aggression and regulation of anger, providing preliminary evidence for the convergent validity of the measure. Factor analysis confirmed that responses loaded on three factors: aggression, avoidance, and assertion. Model fit was adequate (RMSEA = .028) and cross-validated in a second sample (RMSEA = .039). Several types of responses loaded on two factors suggesting that some strategies that youth use to manage provocation are not “pure” examples of these broadband categories. Implications for conceptualization and measurement of youth social behavior are discussed.

Adolescent cancer survivors’ smoking intentions are associated with aggression, attention, and smoking history

The present study examines behavioral and psychosocial factors associated with smoking intentions and experimentation among adolescent survivors of pediatric cancer. Adolescent survivors of brain tumor and acute lymphoblastic leukemia (n = 99) provided information about their smoking histories and their intentions to smoke in the future. Behavior rating scales were completed by survivors, parents, and teachers. Past experimentation with smoking and higher levels of self-reported aggression were associated with intentions to smoke in the future (OR = 4.18, 95% CI 1.02-17.04, and OR = 1.08, 95% CI 1.01-1.15, respectively), while teacher-ratings of inattention in the classroom were negatively associated with intentions to smoke (OR = 0.94, 95% CI.88-.99), all p < .05. Experimentation with smoking was more likely among older survivors (OR = 1.76, 95% CI 1.16-2.66, p < .01) and those whose parents had divorced (OR = 4.40, 95% CI 1.21-16.06, p < .05). A concerning minority of adolescent survivors have clear intentions to smoke, a behavior that adds to their overall health risk. Smoking intentions and experimentation are important precursors to regular smoking. Prevention efforts are needed to interrupt the progression from intentions and experimentation to established smoking and nicotine dependence in this medically vulnerable population. Assessment of an adolescent's history of parental divorce, past experimentation with smoking, and aggressive behavior will identify those survivors who are likely to consider smoking in the future. Screening for these characteristics will allow clinicians to be more vigilant in health promotion.

Stages of Change and the Group Treatment of Batterers: A Randomized Clinical Trial

A stages-of-change motivational interviewing (SOCMI) treatment approach was compared with a standard cognitive behavioral therapy gender reeducation (CBTGR) approach in a sample of 528 English-speaking and Spanish-speaking male batterers who were randomly assigned to 49 26-week groups in either condition. Blind ratings of therapist adherence differentiated the two conditions. Language spoken neither predicted outcome nor interacted with treatment. The SOCMI curriculum led to significant reductions in female partners' reports of physical aggression at follow-up, but not to changes in self-reported aggression. Men who were initially less ready to change benefited more from the SOCMI approach while men who were more ready to change benefited more from the CBTGR approach. Results suggest the importance of tailoring abuser intervention programs to individuals' initial readiness to change.

Developmental trajectories of physical aggression: prediction of overt and covert antisocial behaviors from self- and mothers' reports.

Physical aggression declines for the majority of children from preschool to elementary school. Although this desistance generally continues during adolescence and early adulthood, a small group of children maintain a high level of physical aggression over time and develop other serious overt and covert antisocial behaviors. Typically, researchers have examined relations of developmental changes in physical aggression to later violence with teachers' or mothers' reports on surveys. Little is known about the degree to which children's self-reported physical aggression predicts later antisocial behavior. The longitudinal study in this article had a staggered, multiple cohort design. Measures of physical aggression were collected through self- and mother reports from age 11-14 years, which were used to construct trajectory groups (attrition was 6 and 14% from age 11-14, respectively, for self- and mother reports). Overt and covert antisocial behaviors were self-reported at age 18-19 years (attrition was 36% from age 11 to 18-19). Four trajectory groups (low stable, 11%; moderate-low declining, 34%; moderate declining, 39%; high stable, 16%) were identified from self-reports, whereas three trajectories (low declining, 33%; moderate declining, 49%; high stable, 18%) were identified from mothers' ratings. We examined the prediction of overt and covert antisocial behaviors in early adulthood from the high stable and the moderate declining trajectories. According to both informants, higher probability of belonging to the high stable group was associated with higher overt and covert antisocial behavior, whereas higher probability of belonging to the moderate declining group was associated with higher covert antisocial behavior. Our results support the value of children's as well as mothers' reports of children's aggression for predicting different types of serious antisocial behavior in adulthood.

The latent structure of childhood aggression: A taxometric analysis of self-reported and teacher-rated aggression in Israeli schoolchildren.

The purpose of this study was to determine whether the latent structure of childhood aggression, like the latent structure of adult antisocial behavior, is dimensional. One thousand and five Israeli schoolchildren completed a translation of the Buss-Perry Aggression Questionnaire (AQ; Buss & Perry, 1992) and were rated by their homeroom teachers on the Eyberg Child Behavior Inventory (ECBI; Robinson, Eyberg, & Ross, 1980). The AQ Physical Aggression and Verbal Aggression scales were combined to form the 1st indicator, the AQ Anger and Hostility scales were combined to form the 2nd indicator, the 10-item ECBI Oppositional Defiant Behavior Toward Adults scale composed the 3rd indicator, and the 8-item ECBI Conduct Problem Behavior scale composed the 4th indicator. Subjecting these indicators to taxometric analysis revealed consistent support for dimensional latent structure in the full sample as well as in 5 of the 6 subsamples. Childhood aggression, it would seem, differs quantitatively along a dimension (degree of aggression) rather than bifurcating into qualitatively distinct categories (aggressive vs. nonaggressive).

Capturing the friendship context with a collective property: Friendship group engagement vs. disaffection

The purpose of this study was to introduce a motivational property of the group, friendship group engagement vs. disaffection, and to examine different composition models for combining individual reports into an indicator of a group-level property. Data were collected from 312 ninth grade students and their teachers. Self-reported friendship group (FG) engagement and disaffection were related to self-reported classroom engagement, aggression, and peer problem behavior, but not to teacher-reported classroom engagement. Group-reported FG engagement and disaffection were related to self-reported FG engagement and disaffection, classroom engagement, aggression, and peer problem behavior, but these relationships were moderated by within-group agreement on the group property. Findings underscore the importance of a priori conceptualization of group-level properties that are theoretically linked to adolescent adjustment, and the need to consider composition models when aggregating individual reports to create profiles of the group. Implications for future work on capturing properties of friendship groups are discussed.

Effects of a Brief Intervention for Reducing Violence and Alcohol Misuse Among Adolescents

Emergency department (ED) visits present an opportunity to deliver brief interventions to reduce violence and alcohol misuse among urban adolescents at risk of future injury. To determine the efficacy of brief interventions addressing violence and alcohol use among adolescents presenting to an urban ED. Between September 2006 and September 2009, 3338 patients aged 14 to 18 years presenting to a level I ED in Flint, Michigan, between 12 pm and 11 pm 7 days a week completed a computerized survey (43.5% male; 55.9% African American). Adolescents reporting past-year alcohol use and aggression were enrolled in a randomized controlled trial (SafERteens). All patients underwent a computerized baseline assessment and were randomized to a control group that received a brochure (n = 235) or a 35-minute brief intervention delivered by either a computer (n = 237) or therapist (n = 254) in the ED, with follow-up assessments at 3 and 6 months. Combining motivational interviewing with skills training, the brief intervention for violence and alcohol included review of goals, tailored feedback, decisional balance exercise, role plays, and referrals. Self-report measures included peer aggression and violence, violence consequences, alcohol use, binge drinking, and alcohol consequences. About 25% (n = 829) of screened patients had positive results for both alcohol and violence; 726 were randomized. Compared with controls, participants in the therapist intervention showed self-reported reductions in the occurrence of peer aggression (therapist, -34.3%; control, -16.4%; relative risk [RR], 0.74; 95% confidence interval [CI], 0.61-0.90), experience of peer violence (therapist, -10.4%; control, +4.7%; RR, 0.70; 95% CI, 0.52-0.95), and violence consequences (therapist, -30.4%; control, -13.0%; RR, 0.76; 95% CI, 0.64-0.90) at 3 months. At 6 months, participants in the therapist intervention showed self-reported reductions in alcohol consequences (therapist, -32.2%; control, -17.7%; odds ratio, 0.56; 95% CI, 0.34-0.91) compared with controls; participants in the computer intervention also showed self-reported reductions in alcohol consequences (computer, -29.1%; control, -17.7%; odds ratio, 0.57; 95% CI, 0.34-0.95). Among adolescents identified in the ED with self-reported alcohol use and aggression, a brief intervention resulted in a decrease in the prevalence of self-reported aggression and alcohol consequences. clinicaltrials.gov Identifier: NCT00251212.

Young men's intimate partner violence and relationship functioning: long-term outcomes associated with suicide attempt and aggression in adolescence

Longitudinal research supports that suicidal thoughts and behaviors in adolescence predict maladjustment in young adulthood. Prior research supports links between suicide attempt and aggression, perhaps because of a propensity for impulsive behavior in states of high negative affect that underlies both problems. Such vulnerability may increase risk for intimate partner violence and generally poor young adulthood relational adjustment. A total of 153 men participated in annual assessments from ages 10-32 years and with a romantic partner at three assessments from ages 18-25 years. Multi-method/multi-informant constructs were formed for parent/family risk factors, adolescent psychopathology (e.g. suicide-attempt history, mother-, father-, teacher- and self-reported physical aggression) and young adulthood relational distress (jealousy and low relationship satisfaction) and maladaptive relationship behavior (observed, self- and partner-reported physical and psychological aggression toward a partner, partner-reported injury, official domestic violence arrest records and relationship instability). Across informants, adolescent aggression was correlated with suicide-attempt history. With few exceptions, aggression and a suicide attempt in adolescence each predicted negative romantic relationship outcomes after controlling for measured confounds. Adolescent aggression predicted young adulthood aggression toward a partner, in part, via relationship dissatisfaction. Boys' aggression and suicide-attempt history in adolescence each predict poor relationship outcomes, including partner violence, in young adulthood. Findings are consistent with the theory of a trait-like vulnerability, such as impulsive aggression, that undermines adaptation across multiple domains in adolescence and young adulthood. Prevention and intervention approaches can target common causes of diverse public health problems.

Narcissistic personality disorder and self-esteem: An examination of differential relations with self-report and laboratory-based aggression

A controversy exists regarding the strength and replicability of relations between self-related constructs of self-esteem and narcissism in relation to aggression. Methodological issues have been posited to be responsible for these inconsistent results including an over-reliance on self-report measures and the use of dissimilar measures of aggression. In the current study, we examined the relations among Narcissistic personality disorder (NPD), self-esteem and aggression in two samples. Both self-report and interview ratings of NPD were correlated with both laboratory-based and self-reported aggression. Alternatively, self-esteem manifested primarily nonsignificant relations with aggression, except when controlling for the variance shared with NPD. The current results add to the extant literature suggesting that narcissism may be the more powerful correlate of aggressive behavior.

The Relationship Between Parents' Verbal Aggression and Young Adult Children's Intimate Partner Violence Victimization and Perpetration

This study examines the relationships between perceived and self-reported parent verbal aggression and their young adult children's intimate partner violence (IPV) victimization and perpetration. Two hundred undergraduate students completed an in-person self-administered survey measuring IPV victimization and perpetration, as well as perceived parent verbal aggression. Three-hundred and eighty-six mail surveys were also sent to their parents; 79% of parents returned the surveys. Results indicate that perceived mother and father verbal aggression was related to higher levels of victimization and perpetration across several forms of IPV for both daughters and sons. The data appear to support theory that suggests parents of the same sex as their children are stronger models for aggressive behavior (Bandura, 1986). In addition, there were some differences in perceived and self-reported data for ratings of parent verbal aggression. Results of this investigation indicate that perceived parent communication has a significant impact on young adult children's victimization and perpetration of violence in intimate partner relationships. The findings also suggest that interventions aimed at developing and enhancing parent communication skills can help prevent or reduce the risk of young adult children becoming involved in violent relationships, as well as reducing risk factors for other adverse health problems.

Deployment and the Probability of Spousal Aggression by U.S. Army Soldiers

To determine the relationship between length of soldier deployment and self-reports of moderate and severe spousal violence. The Conflict Tactics Scale was used to measure self-reports of behaviors exhibited in marital conflict. Surveys were administered to a 15% random sample of 26,835 deployed and nondeployed married active duty U.S. Army men and women in the 50 United States during the period 1990 to 1994. Multinomial logistic regression and ordered probit analysis were used to estimate the probabilities of moderate and severe violence by length of deployment. After controlling for demographic variables, the probability of severe aggression was significantly greater for soldiers who had deployed in the past year compared with soldiers who had not deployed. Deployment contributes a significant but small increase to the probability of self-reported spousal aggression during a 1-year period. Although deployment is a military operation, similar effects may be observed in certain civilian occupations.

Peer group self-identification as a predictor of relational and physical aggression among high school students.

Adolescent peer group self-identification refers to adolescents' affiliation with reputation-based peer groups such as "Goths" or "Jocks." These groups tend to vary on normative characteristics, including the group members' attitudes and behaviors. This article examined whether adolescents' baseline peer group self-identification predicted their self-reported relational and physical aggression 1 year later. Self-report data were collected from 1614 students from 9 regular and 9 continuation (alternative) high schools in Southern California, at baseline and 1-year follow-up. Subjects' mean baseline age was 15.21 years (SD = 1.18) and 51.6% of the subjects were female. Findings indicated that compared with self-identified "Regular" or "Normal" students, adolescents who identified with high-risk peer groups (eg, "Druggies,""Goths") tended to report higher relational and physical aggression 1 year later, controlling for baseline aggression and demographic variables. In addition, adolescents' self-identification with high-status peer groups (eg, "Jocks,""Populars") was predictive of higher relational aggression 1 year later. Gender and school type (ie, regular vs continuation) were not found to moderate these effects. It appears that peer group self-identification is a salient predictor of physical and relational aggression across gender and school type. Adolescents who identify with high-risk peer groups tend to report higher levels of physical as well as relational aggression in the future. In addition, adolescents who affiliate with elite groups tend to become more relationally aggressive over time. School-based prevention programs targeting aggression may benefit from addressing the impacts of peer group self-identification on adolescents' aggressive behavior.
