Smeijers D, Denson TF, Bulten EH, Brazil IA. Validity and reliability of the Dutch version of the displaced aggression questionnaire. World J Psychiatry 2021; 11:1288-1300. [PMID: 35070778 PMCID: PMC8717039 DOI: 10.5498/wjp.v11.i12.1288] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 07/13/2021] [Accepted: 11/04/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Displaced aggression occurs when a person encounters a provoking situation, is unable or unwilling to retaliate against the original provocateur, and subsequently aggresses against a target that is not the source of the initial provocation. The displaced aggression questionnaire (DAQ) was developed to measure individual differences in the tendency to displace aggression.
AIM To develop a Dutch version of the DAQ and examine relationships between the DAQ and novel individual differences.
METHODS The Dutch version of the DAQ was created using a back-translation procedure. Undergraduate students (n = 413) participated in the current study. The questionnaires were administered online.
RESULTS The results confirmed the original three-factor structure and showed good reliability and validity. We also found differential relationships between trait displaced aggression, social anxiety and cognitive distortions.
CONCLUSION The results may indicate that distinct patterns exist in the development of the different dimensions of trait displaced aggression. This study adds to the growing cross-cultural literature showing the robustness of trait displaced aggression in several different cultures.

Lobbestael J, Cima MJ. Virtual Reality for Aggression Assessment: The Development and Preliminary Results of Two Virtual Reality Tasks to Assess Reactive and Proactive Aggression in Males. Brain Sci 2021; 11:1653.

Abstract
Validly measuring aggression is challenging because self-reports are plagued with biased answer tendencies and behavioral measures with ethical concerns and low ecological validity. The current study, therefore, introduces a novel virtual reality (VR) aggression assessment tool, differentially assessing reactive and proactive aggression. Two VR tasks were developed, one in an alley environment (N = 24, all male, Mage = 23.88, 83.3% students) and an improved second one in a bar (N = 50, all male, Mage = 22.54, 90% students). In this bar VR task, participants were randomly assigned to either the reactive condition where they were triggered by a cheating and insulting dart-player or to the proactive condition where they could earn extra money by aggressing. Participants' level of self-reported aggression and psychopathy was assessed, after which they engaged in either the reactive or proactive VR task. Changes in affect and blood pressure were also measured. Aggression in the reactive VR task was evidenced to mostly display convergent validity because it positively correlated with self-reported aggression and total and fearless dominance factor scores of psychopathy, and there was a trend relationship with increased systolic blood pressure. The validity of the proactive aggression variant of our VR bar paradigm received less support, and needs more refinement. It can be concluded that VR is a potentially promising tool to experimentally induce and assess (reactive) aggression, which has the potential to provide aggression researchers and clinicians with a realistic and modifiable aggression assessment environment.

Testing the Effects of a Virtual Reality Game for Aggressive Impulse Management: A Preliminary Randomized Controlled Trial among Forensic Psychiatric Outpatients. Brain Sci 2021; 11:brainsci11111484.

Abstract
Prior laboratory experiments among healthy samples found that training avoidance movements to angry faces may lower anger and aggression, especially people high in trait anger. To enrich this training and make it more suitable for clinical applications, the present researchers developed it into a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME). The current study examined the effects of this training in a randomized controlled trial among forensic psychiatric outpatients with aggression regulation problems (N = 30). In addition to the aggression replacement training, patients played either the VR-GAIME or a control game. Aggressive behavior was measured pre-, half-way, and post-treatment via self-report and clinicians ratings. No difference was found between the VR-GAIME and the control game. However, the participants reported gaining more insight into their own behavior and that of others. Future VR intervention tools in clinical settings may capitalize more on their benefits for self-reflection within interpersonal settings.

Abstract
OBJECTIVE We aim to provide a publicly available Hungarian version of the BPAQ; compare the BPAQ factors to other personality traits; and compare both the original BPAQ factor structure provided by Buss and Perry (J. Pers. Soc. Psychol., 63, 1992, 452), the revised BPAQ-SF factor structure by Bryant and Smith (J. Res. Pers., 35, 2001, 138), and the BAQ by Webster et al. (Aggress. Behav., 40, 2014, 120). METHODS The validation of the Hungarian version of the BPAQ was carried out on a Hungarian university sample (N = 841). There were three main focuses of data analysis: descriptive statistics, correlations, and confirmatory factor analyses. RESULTS CFA-related statistics showed an adequate fit for the BPAQ 4 factors; however, contrary to prior validations of BPAQ, we were not able to clearly define the verbal aggression factor. We found that the shorter form of the BPAQ has a better model fit on our sample than the original form, while the model fit of the BAQ was in-between these. BPAQ scales showed low to moderate relationship with the Barratt Impulsivity Scale and Hospital Anxiety and Depression Scale. CONCLUSION Both the BPAQ and the BPAQ-SF, also the BAQ provide acceptable model fitting on a Hungarian sample of university students. While most of BPAQ items provided adequate loadings on their hypothesized factors, two items (21 and 27) did not. We argue this is the result of conceptual inaccuracy of the original items.

Abstract
OBJECTIVE In forensic psychiatric patients, sleep problems as well as impulsivity and aggression are highly prevalent, yet studies on their association over time are lacking. This study investigates the association between sleep quality and changes in impulsivity and aggression in forensic psychiatric patients over one year. METHODS Data were drawn from an ongoing prospective observational study in adult forensic psychiatric patients admitted to a forensic treatment facility between October 2006 and January 2018. Validated self-reports and observational instruments were used to assess sleep quality, impulsivity and aggression upon admission to the hospital and after one year. Linear regression analyses were performed to examine the association between sleep quality, impulsivity and aggression. All models were adjusted for baseline values of outcome measures, demographic features and general psychopathology. RESULTS Data from 83 men (age 37.7 ± 11.7 years) with completed consecutive measurements were analyzed. Poor sleep quality was associated with increased self-reported aggression (β = 1.08; 95% CI, 0.38-1.78). This association was positively confounded by general psychopathology, indicating that sleep quality is specifically related to self-reported aggression instead of being part of general psychopathology (adjusted β = 1.18; 95% CI, 0.39-1.97). Poor sleep quality was not associated with changes in self-reported impulsivity, clinician-rated impulsivity or clinician-rated hostility in this population. CONCLUSION Poor sleep quality was associated with an increase in self-reported aggression over one year in male forensic psychiatric patients. Early evaluation and treatment of sleep problems in (forensic) psychiatric patients may play an important role in reducing the risk of aggressive behavior.

Abstract
Background: Prior laboratory findings indicate that training avoidance movements to angry faces may lower anger and aggression among healthy participants, especially those high in trait anger. To enrich this training and make it more suitable for clinical applications, it has been developed into a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME). Methods: The proposed study will examine the effects of this training in a randomized controlled trial among forensic psychiatric outpatients with aggression regulation problems (N = 60). In addition to the aggression replacement training, participants will play either the VR-GAIME or a control game. Anger will be assessed using self-report. Aggressive impulses will be measured via self-report, a validated laboratory paradigm, and rated by clinicians. Discussion: The authors hypothesize that the combination of the VR-GAIME and regular aggression treatment will be more successful in reducing aggressive behavior. One of the strengths of the proposed study is that it is the first to examine the effects of a motivational intervention in a clinical sample characterized by problems in regulating anger and aggression. Another strength of the proposed study is that the VR-GAIME will be implemented as a multi-session intervention. Additionally, the VR-GAIME applies, for the first time, serious gaming and virtual reality on an avoidance motivation intervention. If positive results are found, the VR-GAIME may be systematically deployed in forensic psychiatric settings. Trial registration: The trial is registered with The Netherlands National Trial Register, number: NTR6986.

Effect of the interaction between oxytocin receptor gene polymorphism (rs53576) and stressful life events on aggression in Chinese Han adolescents. Psychoneuroendocrinology 2018; 96:35-41. [PMID: 29890447 DOI: 10.1016/j.psyneuen.2018.06.002] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Revised: 04/25/2018] [Accepted: 06/02/2018] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Accumulating evidence suggests that stressful life events are associated with increased risk for aggressive behavior in adolescents; however, aggressive reactions to life stressors exhibit large individual differences. The present study sought to examine whether the interaction between a single nucleotide polymorphism (SNP [rs53576]) within the oxytocin receptor gene (OXTR) and stressful life events is related to aggression in Chinese Han adolescents. METHODS A total of 197 Chinese Han adolescents (14-17 years of age) were included in this study. Aggression was assessed using the 12-item short version of Buss and Perry Aggression Questionnaire. Stressful life events during the past 12 months were assessed using the Adolescent Self-Rating Life Events Checklist. Genomic DNA was extracted from saliva and buccal cells from each individual. RESULTS Multivariate analysis of variance yielded a significant interaction between OXTR rs53576 SNP and life stress (F = 2.449, p = 0.043, partial η2 = 0.051) and of sex × SNP × life stress (F = 3.144, p = 0.016, partial η2 = 0.064). High life stress during the past 12 months was associated with high levels of physical aggression and hostility in OXTR rs53576 homozygous AA adolescents but not in G-carrier adolescents. In boys, homozygous AA individuals in the high life stress group reported significantly higher levels of physical aggression than participants in the other three groups; the interaction, however, was not significant in girls. CONCLUSIONS This study, which analyzed a specific gene-environment interaction, demonstrated that AA OXTR rs53576 homozygosity may correlate with higher levels of aggression under high life stress conditions with a sample of healthy Chinese Han adolescents. These findings promote the etiological understanding of adolescent aggression, highlighting the complex effect of stressful life events on aggression, and adding evidence supporting the relationship between the oxytocin system and aggressive behavior in adolescents.

Abstract
Aggression replacement training (ART) is widely used to reduce aggression. Results regarding its effectiveness, however, are inconclusive regarding adults and specific populations displaying severe aggression. The current open uncontrolled treatment study aimed at assessing the social skills and anger control modules of the ART to reduce aggression in forensic psychiatric outpatients (FPOs). Furthermore, characteristics associated with treatment outcome and dropout were examined. The results suggested that aggression changed during the ART. In addition, higher baseline levels of trait aggression were associated with greater reductions of aggression, whereas more cognitive distortions were associated with less reduction. Treatment dropouts were characterized by higher levels of psychopathic traits, proactive aggression, and more weekly substance use. As there was a considerable amount of dropout; it is important to assess risk of dropping out of treatment and, subsequently, improve treatment motivation. This might enhance treatment adherence which may lead to a more successful reduction of aggression.

Abstract
Aggression Replacement Training (ART) is widely used to reduce aggression and is considered to be effective although there are also inconsistent results. Studies investigating the effectiveness of ART do not focus on neurocognitive characteristics. Focusing on these aspects would result in enhanced understanding of underlying mechanisms of ART. The current open uncontrolled treatment study assessed whether neurocognitive characteristics were associated with change in aggression during the social skills and anger control modules of ART among forensic psychiatric outpatients. Furthermore, differences between treatment dropouts and completers and change in these characteristics during ART were examined. A reduction of trait aggression, cognitive distortions, and social anxiety was observed. Neurocognitive characteristics were not associated with change in aggression, could not distinguish treatment completers from dropouts, and did not change after ART. It is suggested that new paradigms should be developed which take into account the social context in which these impairments appear.

Abstract
The most studied bimodal classifications of aggressive behavior are the impulsive/premeditated distinction measured with the Impulsive Premeditated Aggression Scale and the reactive/proactive distinction measured with the Reactive Proactive Questionnaire. The terms of these classifications are often used interchangeably, assuming that reactive aggression is equivalent to impulsive aggression and that proactive aggressive behavior is the same as premeditated aggression. The correspondence or discrepancy between both aggression classifications/questionnaires, however, is understudied. Therefore, the current study investigated the correspondence between the RPQ and IPAS in a sample of 161 forensic psychiatric outpatients (FPOs) with severe aggressive behavior. Correlation analysis revealed a limited correspondence between the RPQ and IPAS. Cluster analyses derived three clusters from the RPQ as well as the IPAS: these clusters did not match in 60.3% of the cases. Furthermore, the notion that the RPQ measures trait aggression whereas the IPAS assesses state aggression could not be verified. The present study indicates that aggression subtypes as measured by use of the RPQ and IPAS correspond only partially and should not be used interchangeably. Furthermore, it was suggested that RPQ focuses more on actual aggressive behavior and the IPAS more on emotions and their regulation. Future research is needed to elucidate the applicability of both questionnaires in further detail.

Abstract
Individuals with aggression regulation disorders tend to attribute hostility to others in socially ambiguous situations. Previous research suggests that this "hostile attribution bias" is a powerful cause of aggression. Facial expressions form important cues in the appreciation of others' intentions. Furthermore, accurate processing of facial expressions is fundamental to normal socialization. However, research on interpretation biases in facial affect is limited. It is asserted that a hostile interpretation bias (HIB) is likely to be displayed by individuals with an antisocial (ASPD) and borderline personality disorder (BPD) and probably also with an intermittent explosive disorder (IED). However, there is little knowledge to what extent this bias is displayed by each of these patient groups. The present study investigated whether a HIB regarding emotional facial expressions was displayed by forensic psychiatric outpatients (FPOs) and whether it was associated with ASPD and BPD in general or, more specifically, with a disposition to react with pathological aggression. Participants of five different groups were recruited: FPOs with ASPD, BPD, or IED, non-forensic patients with BPD (nFPOs-BPD), and healthy, non-aggressive controls (HCs). Results suggest that solely FPOs with ASPD, BPD, or IED exhibit a HIB regarding emotional facial expressions. Moreover, this bias was associated with type and severity of aggression, trait aggression, and cognitive distortions. The results suggest that a HIB regarding facial expressions is an important characteristic of pathological aggressive behavior. Interventions that modify the HIB might help to reduce the recurrence of aggression. Aggr. Behav. 43:386-397, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
Current approaches in Dutch mental health care institutions towards inpatients' aggression have focused predominantly on environmental factors, such as training the staff in aggression management. However, personality traits might be an important factor in patients' aggression - as shown by incidents in the wards. This study explores the influence of dysfunctional impulsivity and alexithymia on psychiatric patients' aggressive behavior, through self-reports and through involvement in aggressive incidents. Personality traits influencing patients' aggression emphasize the importance of a more direct approach to their aggression. Clinical patients at Dutch mental health care institution Emergis (n=84) filled out questionnaires about their aggressiveness (using Buss and Perry's Aggression Questionnaire Short Form), dysfunctional impulsivity and alexithymia. Multiple regression analyses indicated that dysfunctional impulsivity positively related to self-reported aggressive behavior. The relationship, however, could not be confirmed for inpatients' aggression as reported by the staff on the wards. Unexpectedly affective alexithymia negatively related to hostility. Gender differences in self-reported aggression were found. Female patients showed higher levels of hostility. Regression analyses indicated that the male gender positively related to physical aggression. Findings emphasize the importance of a new approach in Dutch mental health care, in which patients may engage in aggression-regulation training programs.

Abstract
The current study aims to ascertain how different variants of callous-unemotional traits differ in their psychopathology, exposure to aggression and violence, and aggressive and violent behavior. If secondary/distressed variants (high in callous-unemotional traits and high in anxiety) and primary/traditional variants (high in callous-unemotional traits and low in anxiety) differ along these dimensions, it may speak to their different etiologies, treatment needs (e.g., trauma focused), and responsiveness to treatment. The current sample consisted of 799 adolescents from high schools (n = 419) and juvenile detention centers (n = 380). Participants were interviewed regarding their callous-unemotional traits, psychopathology, exposure to aggression and violence, and aggressive and violent behavior. Parents/guardians and teachers/staff members also reported on participants' callous-unemotional traits and aggressive and violent behavior. A model-based cluster analysis indicated that there were four clusters in the data set, based on callous-unemotional traits and anxiety: a nonvariant cluster, a primary/traditional callous-unemotional cluster, a secondary/distressed callous-unemotional cluster, and a "fearful" cluster. Secondary/distressed variants of psychopathy exhibited significantly greater symptoms of depression and psychoticism, more exposure to low level aggression and neighborhood violence, and more aggressive and violent behavior, as compared to the other clusters. Adolescents with callous-unemotional traits might not be a homogeneous group, but rather may differ in attitudes, behaviors, and exposure to risk, therefore differing in their treatment needs and responsiveness.

Abstract
The study assesses the psychometric properties of the Greek version of the Aggression Questionnaire by Buss and Perry in a sample of 760 Greek high school students. This questionnaire has been widely used to study Physical Aggression, Verbal Aggression, Anger, and Hostility. A confirmatory factor analysis of responses showed adequate fit for the original 4-factor model (total variance explained: 68.2%). The analysis also showed satisfactory internal consistency and temporal stability over 6 to 8 weeks. Also, the construct validity, extreme groups' validity, and predictive validity indices were adequate. Greek female students adopted more indirect forms of aggression (Hostility) than males, who applied more direct forms such as Physical Aggression. Findings supported the use of the Greek version of the questionnaire for assessment in high school students.

Relationships of diet-related blood parameters and blood lead levels with psychopathology and aggression in forensic psychiatric inpatients. CRIMINAL BEHAVIOUR AND MENTAL HEALTH : CBMH 2016; 26:196-211.

Abstract
BACKGROUND Earlier studies have suggested associations between diet-related blood parameters and both aggression and psychopathological symptoms, but little is known about this in forensic psychiatric inpatients. AIM This article aims to explore the levels of diet-related blood parameters and their relationship to aggressive behaviour and/or psychopathology among Dutch forensic psychiatric inpatients. METHODS Minerals, vitamins, lead and fatty acid levels were measured in blood samples from 51 inpatients, well enough to consent and participate in the study, from a possible total of 99. Levels of aggression and psychopathology were assessed using questionnaires, observation instruments and clinical data. Associations between blood parameters and behavioural measures were calculated. RESULTS Low average levels of vitamin D3 and omega (ω)-3 fatty acids were found, with nearly two-thirds of the patients having below recommended levels of D3 , while vitamin B6 levels were high. Magnesium, iron, zinc, copper and lead were overall within reference values, but copper/zinc ratios were high. Several significant associations between levels of fatty acid measures and both aggression and psychopathology were observed. CONCLUSION In our sample of forensic psychiatric inpatients, fatty acids - but not mineral or vitamin levels - were associated with aggression and psychopathology. A potentially causal link between fatty acids and aggression could be tested in a randomised, placebo-controlled trial of fish oil supplements. General health of such patients might be improved by better vitamin D status (increased sun exposure and/or supplement use) and better ω-3 fatty acid status (oily fish or fish oil consumption), but discouraging unnecessary self-prescription of B vitamins where necessary.

Abstract
OBJECTIVE This study aims to establish a cut score for the Inventory of Callous-Unemotional Traits, a well-validated measure of callous-unemotional (CU) traits in youth for which there is currently no cutoff score. METHOD We analyzed data on 634 adolescents from high schools (n = 343) and juvenile detention centers (n = 291). Participants, their parents and guardians, and their teachers and staff members reported on participants' CU traits and aggressive/violent behavior. RESULTS All three reports of CU traits as well as intersource composites were associated with aggression, violence, and detained status. Parent report was a better indicator compared to self-reports and teacher reports. Appropriate cut scores based on each report and composite were determined. CONCLUSION We recommend that information from all available informants should be used whenever possible, but when only one informant report is feasible, parent reports are preferable.

Abstract
The aim of the present study was to validate the Buss-Perry Aggression Questionnaire-Short Form (BPAQ-SF) among Portuguese juvenile delinquents. With a total sample of 237 male participants, subdivided into an incarcerated forensic sample (n=192) and a community sample (n=45), the Portuguese version of the BPAQ-SF demonstrated good psychometric properties in terms of factor structure, internal consistency, convergent validity, discriminant validity, predictive validity and known-groups validity that generally justify its use among Portuguese youth. Statistically significant associations were found with drug use and alcohol abuse.

Abstract
To date, most studies regarding the social-psychological effects of martial arts and combat sports (MA&CS) on young people focus on measuring effects without considering mediating factors. The aim of the present study was to analyze three mediating factors that might be influential when examining outcomes of MA&CS for youth (i.e., the type of MA&CS, participants' characteristics, and social background). Young MA&CS participants ( N = 477, M age = 14.0 yr., SD = 2.13) practicing judo, aikido, kick-/Thai boxing or karate, as well as their parents ( N = 307), were assessed in terms of their goal orientations, aggressiveness, psychosocial behavior, and social background. It was concluded that differences exist in the characteristics and social background of participants depending on the type of MA&CS being practiced. The fact that differences in these mediating factors can be identified indicates that in future research these and possible other mediating factors should be considered when trying to determine social-psychological outcomes of MA&CS.

Abstract
The psychometric properties of an Arabic version of the Aggression Questionnaire-Short Form (AQ-SF) were examined in 2 samples of Egyptian and Omani adolescents. Confirmatory factor analysis (CFA) revealed that the 4-factor model had adequate fit to the data of both samples, whereas the unidimensional and hierarchical models did not. Multigroup CFAs revealed culture invariance for the AQ-SF 4-factor model when the 2 samples were compared for each gender. The analysis also revealed gender invariance for the AQ-SF 4-factor model within the Omani sample. However, the analysis showed partial gender invariance for the AQ-SF 4-factor model within the Egyptian sample. A latent mean analysis showed consistent gender differences on Physical Aggression in the male direction when males and females were compared across and within both samples. The AQ-SF correlated positively and significantly with peer nominations but did not correlate with a measure of social desirability.

Abstract
The purpose of the study was to (a) investigate gender and age differences in physical aggression, verbal aggression, anger, and hostility, and (b) examine the discriminatory power of the Greek version of the Aggression Questionnaire (GAQ) with high school students. The sample of the study consisted of 658 high school students (321 boys and 337 girls), with an age range from 13 to 17 years (M = 15.3, SD = 1.5). The students completed the Aggression Questionnaire adapted to Greek. Regarding gender, the overall correct identification rate in the discriminant analysis showed that 73.3% of the cases were correctly classified. In addition, the results indicated that physical aggression declined with age and that, compared to boys, girls of higher grades apply more indirect forms of aggression, such as anger and hostility. The findings of the study provide important information regarding the expression of aggressive behavior during adolescence.

Abstract
This study reports reliability and validity of the Dutch Reactive-Proactive Aggression Questionnaire (RPQ). In total, 845 participants completed the RPQ along with other measures of aggression. Groups consisted of non-offender participants, criminal offenders, youngsters (age 6-18), and adults (age above 18). Test-retest stability in a subsample of 324 childhood arrestees was good (all ICC's > 0.41). A confirmatory factor analysis supported the same two-factor structure as in the original RPQ. Convergent validity was adequate (all r's > 0.16). Moreover, results demonstrated that the proactive and reactive subscales were differentially related to measurements of callousness and impulsiveness, respectively. Criterion validity was shown in that non-offender subjects demonstrated significantly lower RPQ scores than offender samples. Finally, construct validity was demonstrated in that violent offenders showed higher aggression scores than non-violent offenders. Proactive aggression showed different developmental trajectories within non-offender versus criminal samples, indicating that this form of aggression may be more pathological.

Abstract
Personality disorder is prevalent among offenders with intellectual disabilities (ID), and it is associated with their risk for violence and recurrent offending behaviour. A new staff-rated instrument, the Personality Disorder Characteristics Checklist (PDCC), designed to screen for ICD-10 dissocial and emotionally unstable personality characteristics was evaluated for its reliability and validity, as applied to 129 male forensic patients with ID. Internal consistency and test-retest reliability were very good. Supportive evidence for concurrent and discriminant validity was obtained in conjunction with an established staff-rated instrument, but not for patient self-report measures. Construct validity support was found for the PDCC in association with violent offence and hospital assault history and in significantly accounting for the number of physical assaults in hospital, controlling for multiple covariates. Results for the new measure were favourable in comparison to established instruments. It clinical utility for treatment planning and for the management of risk is discussed.

Abstract
The Inventory of Callous-Unemotional (CU) Traits (ICU) is a self-report questionnaire which was developed to measure the affective features of psychopathy in children and adolescents. Previous studies reported both support and difficulties with this promising new measure. The present study investigated the psychometric and discriminating qualities of the Dutch questionnaire across different groups by examining its structure, distribution and correlates. The ICU was administered to young clinical offenders (detained, N=127), healthy controls (community, N=172), non-clinical offenders (not detained, N=42) and an externalizing non-offender group (under treatment for behavioral problems, N=42). The age range for all groups was 13-20years. Since confirmatory factor analysis of models from earlier research did not yield an acceptable fit, exploratory factor analysis was conducted. Five factors were extracted: Lack of Conscience, Uncaring, Unemotional, Callousness and Lack of Empathy. The results indicated moderate to good test-retest stability and adequate internal consistency. CU traits correlated well with measures of conduct problems and aggression, indicating a good criterion and convergent validity. Results indicate weak associations with expert (Psychopathy Checklist: Youth Version, PCL:YV) and informant (Antisocial Process Screening Device, APSD) measures of psychopathic traits. Although groups could be differentiated on a statistical basis, no meaningful distinction based on CU traits alone was possible. Results of this study cast doubt on the validity of the current ICU. Suggestions are made for improvement.

Abstract
Less is understood about the relationship between ADHD symptoms and academic performance in adolescents than the relationship in younger children. As such, the aim of the present study was to investigate the prospective relationship between ADHD symptoms and academic performance in a community adolescent sample. Three hundred and twenty-four participants, aged 15 and 16, in their final year of compulsory education, completed measures of ADHD, anxiety, depression, and motivation, and a test of general cognitive ability. Participants were also asked for permission for their academic grades to be viewed on a later occasion (approximately 6 months later). In regression analyses, ADHD symptoms were the most significant independent psychopathological predictor of academic performance, and were almost as significant as motivation and cognitive ability. The results suggest that adolescents with more ADHD symptoms are likely to encounter greater academic difficulties.

Abstract
In an earlier study, improvement of dietary status with food supplements led to a reduction in antisocial behavior among prisoners. Based on these earlier findings, a study of the effects of food supplements on aggression, rule-breaking, and psychopathology was conducted among young Dutch prisoners. Two hundred and twenty-one young adult prisoners (mean age=21.0, range 18-25 years) received nutritional supplements containing vitamins, minerals, and essential fatty acids or placebos, over a period of 1-3 months. As in the earlier (British) study, reported incidents were significantly reduced (P=.017, one-tailed) in the active condition (n=115), as compared with placebo (n=106). Other assessments, however, revealed no significant reductions in aggressiveness or psychiatric symptoms. As the incidents reported concerned aggressive and rule-breaking behavior as observed by the prison staff, the results are considered to be promising. However, as no significant improvements were found in a number of other (self-reported) outcome measures, the results should be interpreted with caution.

Abstract
Research suggests that rumination increases anger and aggression. Mindfulness, or present-focused and intentional awareness, may counteract rumination. Using structural equation modeling, we examined the relations between mindfulness, rumination, and aggression. In a pair of studies, we found a pattern of correlations consistent with rumination partially mediating a causal link between mindfulness and hostility, anger, and verbal aggression. The pattern was not consistent with rumination mediating the association between mindfulness and physical aggression. Although it is impossible with the current nonexperimental data to test causal mediation, these correlations support the idea that mindfulness could reduce rumination, which in turn could reduce aggression. These results suggest that longitudinal work and experimental manipulations mindfulness would be worthwhile approaches for further study of rumination and aggression. We discuss possible implications of these results.

Abstract
The primary aim of the current article was the evaluation of the factorial composition of the Aggression Questionnaire (AQ(29)) in the Greek population. The translated questionnaire was administered to the following three heterogeneous adult samples: a general population sample from Athens, a sample of young male conscripts and a sample of individuals facing problems related to substance use. Factor analysis highlighted a structure similar to the one proposed by Buss and Perry [Buss, A.F., Perry, M., 1992. The Aggression Questionnaire. Journal of Personality and Social Psychology 63, 452-459]. However, the refined 12-item version of Bryant and Smith [Bryant, F.B., Smith, B.D., 2001. Refining the architecture of aggression: a measurement model for the Buss-Perry Aggression Questionnaire. Journal of Research in Personality 35, 138-167] provided a better fit to our data. Therefore, the refined model was implemented in further analysis. Multiple group confirmatory factor analysis was applied in order to assess the variability of the 12-item AQ across gender and samples. The percentage of factor loading invariance between males and females and across the three samples defined above was high (higher than 75%). The reliability (internal consistency) of the scale was satisfactory in all cases. Content validity of the 12-item AQ was confirmed by comparison with the Symptom Check-List 90 Revised.

Abstract
OBJECTIVE This study investigates the clustering of a broad range of health-compromising and delinquent behaviors. We examine whether these behaviors belong to a single but broad cluster, 'risk-taking behavior', and whether the nature and degree of clustering in adolescents differs from that in adults. METHOD A representative sample (N=4395) of the Dutch population aged 12 to 40 (overall response rate 67%), was asked about various health-compromising behaviors, such as alcohol consumption, smoking, illegal drug use, unsafe sexual behavior, physical inactivity, poor nutrition (such as skipping breakfast and not eating fruit and vegetables), poor sleep behavior, unlawful traffic behavior, and delinquent and aggressive behavior. Data were collected from fall 2005 to spring 2006 using internet questionnaires and face-to-face computer-assisted interviews. RESULTS No single broad cluster was found. Instead, there were several separate but interrelated clusters. The contents of these clusters differed between age groups. For young adolescents (12-15) two clusters were identified: Alcohol and Delinquency. For older adolescents (16-18) and adults (19-40) three clusters were identified: Alcohol, Delinquency and Health. CONCLUSION The findings of this study support a more integrated approach to promoting healthier lifestyles, and suggest that the behavior targets of integrated prevention programs should be different for adolescents and adults.

Abstract
The psychometric properties of a Dutch version of Buss and Perry's Aggression Questionnaire (AQ) were examined in a sample of violent forensic psychiatric inpatients and outpatients and a sample of secondary vocational students. The internal consistency, interitem correlations, and item—scale correlations of the subscales Physical Aggression, Anger, and Hostility were good but turned out to be unsatisfactory for the subscale Verbal Aggression. The four-factor structure of the AQ could not be confirmed, but the four-factor structure of a 12-item version (short form) of the AQ, the AQ-SF, produced an acceptable fit. The test—retest reliability of the AQ and AQ-SF total scores was good, although the test—retest reliability of the AQ-SF subscale Physical Aggression was not satisfactory. The validity of both the AQ and AQ-SF could be demonstrated by meaningful correlations with alternative measures of aggression and personality, but inpatients were not found to display higher scores on the AQ or AQ-SF than the students.

Abstract
I developed a Chinese version of the Aggression Questionnaire (Buss & Perry, 1992) by translating scale items into Chinese and subjecting them to standard validation procedures. I used confirmatory factor analysis via structural equation modeling to compare several measurement models. Models based on Buss and Perry's (1992) original four-factor (29-item) scale failed to replicate in the Chinese sample; however, the construct validity of Bryant and Smith's (2001) abridged version of the Aggression Questionnaire received strong overall support. The new 12-item scale demonstrated good fit to the data and adequate internal reliability. Evidence for criterion validity was provided by the scale's sensitivity to differing levels of aggression in males and females. Convergent and discriminant validity received partial support from the pattern of correlations with a measure of anger rumination. Linguistic and metric equivalence were supported by high correlation coefficients between scores on Chinese and English versions of the scale completed by bilingual Chinese on separate occasions. Consistent replications of these preliminary results across three independent samples suggest that the Chinese version of the Aggression Questionnaire may be useful for clinical assessment and cross-cultural research.

Abstract
Alcohol consumption increases aggression, but only in some drinkers. This study extends previous work to show how expectancies for alcohol-induced aggression and dispositional rumination moderate the link between alcohol consumption and alcohol-related aggression and hostility in a sample of 285 men and women. Alcohol-aggression expectancies and quantity of alcohol interacted to predict alcohol-related hostility and aggression. Trait rumination moderated the effect of alcohol consumption on aggressive acts. Finally, women who ruminated were more likely to report alcohol-related aggression than were men who ruminated. These results suggest that alcohol expectancies for aggression and rumination constitute two important cognitive facilitators of alcohol-related aggression and hostility, and that gender plays an important role in these relations.

Abstract
Aggressive and hostile behaviours and anger constitute an important problem across cultures. The Buss-Perry Aggression Questionnaire (AQ), a self-rating scale was published in 1992, and has quickly become the gold-standard for the measurement of aggression. The AQ scale has been validated extensively, but the validation focused on various narrowly selected populations, typically, on samples of college students. Individuals, however, who are at risk of displaying aggressive and hostile behaviours may come from a more general population. Therefore, it is important to investigate the scale's properties in such a population. The objective of this study was to examine the factorial structure and the psychometric properties of the AQ scale in a nationally representative sample of the Hungarian adult population.A representative sample of 1200 subjects was selected by a two-step procedure. The dimensionality and factorial composition of the AQ scale was investigated by exploratory and confirmatory factor analyses. Since spurious associations and increased factorial complexity can occur when the analysis fails to consider the inherently categorical nature of the item level data, this study, in contrast to most previous studies, estimated the correlation matrices subjected to factor analysis using the polychoric correlations. The resulting factors were validated via sociodemographic characteristics and psychopathological scales obtained from the respondents. The results showed that based on the distribution of factor loadings and factor correlations, in the entire nationally representative sample of 1200 adult subjects, from the original factor structure three of the four factors (Physical and Verbal Aggression and Hostility) showed a good replication whereas the fourth factor (Anger) replicated moderately well. Replication further improved when the sample was restricted in age, i.e. the analysis focused on a sample representing the younger age group, comparable to that used in the original Buss-Perry study. Similar to the Buss-Perry study, and other investigations of the AQ scale, younger age and male gender were robustly related to physical aggression. In addition, level of verbal aggression was different between the two genders (with higher severity in males) whereas hostility and anger were essentially the same in both genders.In conclusion, the current study based on a representative sample of adult population lends support to the use of the AQ scale in the general population. The authors suggest to exclude from the AQ the two inverse items because of the low reliability of these items with regard to their hypothesized constructs.

Abstract
Bryant and Smith [(2001). Refining the architecture of aggression: A measurement model for the Buss-Perry Aggression Questionnaire. Journal of Research in Personality, 35, 138-167] refined the 29-item Aggression Questionnaire and obtained a 12-item short form of the AQ that has yet to be validated with samples outside of North America and England. Confirmatory factor analysis (CFA) with two Asian adolescent samples revealed that while the hierarchical AQ model had an acceptable fit to the data, the multidimensional AQ model demonstrated a superior fit. The unidimensional AQ model was shown to be an unacceptable measurement model in both samples. Results obtained replicated previous findings using the original 29-item measure and supported the AQ's multidimensionality. Multigroup CFA analyses revealed partial measurement invariance for the 12-item fourfactor AQ model for both samples with respect to gender. Supplementary t-tests revealed a consistent gender difference on physical aggression in the male direction for both samples and a gender difference on verbal aggression in the male direction only for one sample. No other gender differences were found. These results are consistent with recent meta-analytic research.

Abstract
Previous measures of aggressive personality have focused on direct aggression (i.e., retaliation toward the provoking agent). An original self-report measure of trait displaced aggression is presented. Exploratory and confirmatory factor analyses provided support for a 3-factor conceptualization of the construct. These analyses identified an affective dimension (angry rumination), a cognitive dimension (revenge planning), and a behavioral dimension (general tendency to engage in displaced aggression). The trait measure demonstrated good internal consistency and test-retest reliability as well as convergent and discriminant construct validity. Unlike other related personality measures, trait displaced aggression significantly predicted indirect indicators of real-world displaced aggression (i.e., self-reported domestic abuse and road rage) as well as laboratory displaced aggression in 2 experiments.

Abstract
OBJECTIVE To examine relationships between self-reported attachment style and parental rearing behaviors, on the one hand, and anger/hostility, on the other hand, in a sample of nonclinical adolescents (N=441). METHOD Participants completed (a) a single-item measure of attachment style; (b) a questionnaire measuring perceptions of parental rearing behaviors; and (c) two scales assessing anger and hostility. RESULTS Self-reported attachment style was related to anger/hostility. That is, adolescents who defined themselves as avoidantly or ambivalently attached displayed higher levels of anger/hostility than adolescents who classified themselves as securely attached. Furthermore, perceived parental rearing was also related to anger/hostility. More specifically, low levels of emotional warmth and high levels of rejection, control, and inconsistency were accompanied by high levels of anger/hostility. Finally, regression analyses showed that both attachment status and parental rearing behaviors accounted for a unique and significant proportion of the variance in anger/hostility. CONCLUSION These findings are in keeping with the notion that family environment factors such as attachment style and parental rearing are involved in the development of anger/hostility in youths.
