Low expressing alleles of the MAOA gene (MAOA-L) have been associated with an increased risk for developing an aggressive personality. This suggests an MAOA-L-specific neurobiological vulnerability associated with trait aggression. The neural networks underlying this vulnerability are unknown. The present study investigated genotype-specific associations between resting state brain networks and trait aggression (Buss-Perry Aggression Questionnaire) in 82 healthy Caucasian males. Genotype influences on aggression-related networks were studied for intrinsic and seed-based brain connectivity. Intrinsic connectivity was higher in the ventromedial prefrontal cortex (VMPFC) of MAOA-L compared to high expressing allele (MAOA-H) carriers. Seed-based connectivity analyses revealed genotype differences in the functional involvement of this region. MAOA genotype modulated the relationship between trait aggression and VMPFC connectivity with supramarginal gyrus (SMG) and areas of the default mode network (DMN). Separate analyses for the two groups were performed to better understand how the genotype modulated the relationship between aggression and brain networks. They revealed a positive correlation between VMPFC connectivity and aggression in right angular gyrus (AG) and a negative correlation in right SMG in the MAOA-L group. No such effect emerged in the MAOA-H carriers. The results indicate a particular relevance of VMPFC for aggression in MAOA-L carriers; in specific, a detachment from the DMN along with a strengthened coupling to the AG seems to go along with lower trait aggression. MAOA-L carriers may thus depend on a synchronization of emotion regulation systems (VMPFC) with core areas of empathy (SMG) to prevent aggression.

Impulsive aggression has commonly been associated with a dysfunction of the serotonin (5-HT) system: many, but not all, studies point to an inverse relationship between 5-HT and aggression. As cerebral 5-HT4 receptor (5-HT4R) binding has recently been recognized as a proxy for stable brain levels of 5-HT, we here test the hypothesis in healthy men and women that brain 5-HT levels, as indexed by cerebral 5-HT4R, are inversely correlated with trait aggression and impulsivity. Sixty-one individuals (47 men) underwent positron emission tomography scanning with the radioligand [(11)C]SB207145 for quantification of brain 5-HT4R binding. The Buss-Perry Aggression Questionnaire (BPAQ) and the Barratt Impulsiveness Scale were used for assessment of trait aggression and trait impulsivity. Among male subjects, there was a positive correlation between global 5-HT4R and BPAQ total score (P = 0.037) as well as BPAQ physical aggression (P = 0.025). No main effect of global 5-HT4R on trait aggression or impulsivity was found in the mixed gender sample, but there was evidence for sex interaction effects in the relationship between global 5-HT4R and BPAQ physical aggression. In conclusion we found that low cerebral 5-HT levels, as indexed by 5-HT4R binding were associated with high trait aggression in males, but not in females. © The Author (2016).

Previous studies have reported associations between aggression and Internet addiction disorder (IAD), which has also been linked with anxiety, depression, and impulsiveness. However, the causal relationship between aggression and IAD has thus far not been clearly demonstrated. This study was designed to (a) examine the association between aggression and IAD and (b) investigate the mediating effects of anxiety, depression, and impulsivity in cases in which IAD predicts aggression or aggression predicts IAD. A total of 714 middle school students in Seoul, South Korea, were asked to provide demographic information and complete the Young's Internet Addiction Test (Y-IAT), the Buss-Perry Aggression Questionnaire, the Barratt Impulsiveness Scale-11, the State-Trait Anger Expression Inventory-2, the Beck Anxiety Inventory, the Beck Depression Inventory, and the Conners-Wells Adolescent Self-Report Scale. Three groups were identified based on the Y-IAT: the usual user group (n=487, 68.2%), the high-risk group (n=191, 26.8%), and the Internet addiction group (n=13, 1.8%). The data revealed a linear association between aggression and IAD such that one variable could be predicted by the other. According to the path analysis, the clinical scales (BAI, BDI, and CASS) had partial or full mediating effects on the ability of aggression to predict IAD, but the clinical scales had no mediating effect on the ability of IAD to predict aggression. The current findings suggest that adolescents with IAD seem to have more aggressive dispositions than do normal adolescents. If more aggressive individuals are clinically prone to Internet addiction, early psychiatric intervention may contribute to the prevention of IAD.

A recent [(18)F]FDOPA-PET study reports negative correlations between dopamine synthesis rates and aggressive behavior. Since dopamine is among the substrates for monoamine oxidase A (MAOA), this investigation examines whether functional allelic variants of the MAOA tandem repeat (VNTR) promotor polymorphism, which is known to modulate aggressive behavior, influences dopamine release and aggression in response to violent visual stimuli. We selected from a genetic prescreening sample, strictly case-matched groups of 2×12 healthy male subjects with VNTRs predictive of high (MAOA-High) and low (MAOA-Low) MAOA expression. Subjects underwent pairs of PET sessions (dopamine D2/3 ligand [(18)F]DMFP) while viewing a movie of neutral content, versus violent content. Directly afterwards, aggressive behavior was assessed by the Point Subtraction Aggression Paradigm (PSAP). Finally, PET data of 23 participants and behavioral data of 22 participants were analyzed due to post hoc exclusion criteria. In the genetic prescreening sample MAOA-Low carriers had significantly increased scores on the Buss-Perry Aggression Questionnaire. In the PET-study-group, aggressive behavior under the emotional neutral condition was significantly higher in the MAOA-Low group. Interestingly, the two MAOA-groups showed inverse dopaminergic and behavioral reactions to the violent movie: The MAOA-High group showed higher dopamine release and increased aggression after the violent movie; MAOA-Low subjects showed decreases in aggressive behavior and no consistent dopamine release. These results indicate a possible impact of the MAOA-promotor polymorphism on the neurobiological modulation of aggressive behavior. However, the data do not support approaches stating that MAOA-Low fosters aggression by a simple pro-dopaminergic mechanism. Copyright © 2015 Elsevier Inc. All rights reserved.

REM sleep behavior disorder (RBD) is a parasomnia characterized by motor activity during sleep with dream mentation. Aggressiveness has been considered a peculiar feature of dreams associated with RBD, despite normal score in aggressiveness scales during wakefulness. We aimed to measure daytime aggressiveness and analyze dream contents in a population of patients with Parkinson disease (PD) with and without RBD. This is a single-center prospective observational study; it concerns the description of the clinical features of a medical disorder in a case series. The study was performed in the Department of Neurosciences of the Catholic University in Rome, Italy. Three groups of subjects were enrolled: patients with PD plus RBD, patients with PD without RBD, and healthy controls. The diagnosis of RBD was determined clinically and confirmed by means of overnight, laboratory-based video-polysomnography. For the evaluation of diurnal aggressiveness, the Buss-Perry Aggression Questionnaire (BPAQ) was used. The content of dreams was evaluated by means of the methods of Hall and Van De Castle. Patients with PD without RBD displayed higher levels of anger, and verbal and physical aggressiveness than patients with PD and RBD and controls. Patients with PD and RBD and controls did not differ in hostility. It can be hypothesized that a noradrenergic impairment at the level of the locus coeruleus could, at the same time, explain the presence of RBD, as well as the reduction of diurnal aggressiveness. This finding also suggests a role for REM sleep in regulating homeostasis of emotional brain function. © 2015 Associated Professional Sleep Societies, LLC.

Alcohol dependence (AD) is a common chronic brain disorder precipitated by complex interactions between biological, genetic, and environmental risk factors. Aggression often occurs in the context of AD. Previous studies have shown that Oxytocin (OXT) and OXT receptor (OXTR) are involved in the regulation of aggression. The present study investigated whether variations and interactions of OXT and OXTR genes were associated with AD-related aggression in a genetically homogeneous northern Chinese Han population. Three hundred and twenty-four male AD patients and 510 male healthy controls (HCs) were recruited. A Chinese version of the Buss-Perry Aggression Questionnaire was used as a subjective measurement of aggressive behavior. Three variations, rs2254298, rs53576, and rs6133010 were genotyped using TaqMan and ligase detection reaction for all subjects. Generalized Multifactor Dimensionality Reduction was used to detect interactions between genetic attributes and environmental attributes. The frequencies of alleles and genotypes of rs6133010 were significantly different between AD patients and HCs (p<0.001). In HCs, the effect of genotype GG of rs53576 on hostility aggression was significantly stronger than that of genotype AA and AG (p=0.001 and p=0.004, respectively), and the subjects with the interaction combination of rs6133010AA×rs2254298GG×rs53576AG exhibited significant effect on physical aggression (p=0.0107). The present study found that rs6133010 in the OXT gene is associated with AD in the northern Chinese Han population. The polymorphisms of OXT/R may play a key role in the susceptibility of AD-related aggression. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Research of GABRA2 gene in alcohol use and impulse control suggests its role in aggressive behaviour. The purpose of the present study was to examine the effects of GABRA2 genotype and stressful life events on aggressive behaviour, alcohol use frequency and occurrence of alcohol use disorder in a population representative sample of adolescents followed up from third grade to 25 years of age. The sample consisted of the younger cohort of the longitudinal Estonian Children Personality, Behaviour and Health Study. Aggressive behaviour was rated with the activity scale of af Klinteberg, Illinois Bully Scale and Buss-Perry Aggression Questionnaire. Stressful life events and alcohol use were self-reported. Life history of aggression and lifetime occurrence of psychiatric disorders were estimated in a structured interview. The sample was genotyped for GABRA2 rs279826 and rs279858 polymorphisms that are in strong linkage disequilibrium and yielded very similar findings: Higher number of stressful life events reported at age 15 was associated with increased fighting in A-allele carriers, but not in GG homozygotes. At age 25, A-allele carriers with more stressful life events scored higher on physical aggression than those with less stress, and this was also observed regarding life history of aggression. A-allele carriers exposed to higher stress had consumed alcoholic beverages more frequently at age 15, and by age 25, they had alcohol use disorder with higher prevalence. The results of the present study suggest that the GABRA2 genotype interacts with stress in young people with impact on the development of alcohol use and aggressive behaviour.

Understanding motives for offending is important for the development and delivery of effective interventions. To explore associations between variables with motivational implications and the offence committed in the past year rated by people with antisocial personality disorder and substance use disorder as putting them and their status at most risk. Participants were 127 outpatients from a sample recruited for a pragmatic randomised controlled trial of an intervention for adults attending substance abuse treatment clinics in 13 municipalities in Denmark. Motives for offending were assessed on one occasion, using the Offending Motivation Questionnaire, aggression was assessed using the Buss-Perry Aggression Questionnaire and substance-related problems, including mental state difficulties, were assessed using the Substance Use Risk Profile. Attributing offending to provocation, excitement or financial gain differed substantially by type of offence, whereas attribution of offending to compliance did not. Personality scale scores were associated with attributing offences to provocation, excitement or compliance but not with financial gain. Motives for offending among substance users with antisocial personality disorder must be understood both in light of the type of offence and personality traits. Offending behaviour prevention strategies that draw on these distinctions, run in parallel to treatment for substance use, could improve reduction in recidivism.

Antisocial personality disorder often co-exists with drug and alcohol use disorders. This trial examined the effectiveness of offering psycho-education for antisocial personality disorder in community substance use disorder treatment centers in Denmark. A total of 176 patients were randomly allocated to treatment as usual (TAU, n = 80) or TAU plus a psycho-educative program, Impulsive Lifestyle Counselling (ILC, n = 96) delivered by site clinicians (n = 39). Using follow-up interviews 3 and 9 months after randomization, we examined changes in drug and alcohol use (Addiction Severity Index Composite Scores), percent days abstinent (PDA) within last month, and aggression as measured with the Buss-Perry Aggression Questionnaire-Short Form and the Self-Report of Aggression and Social Behavior Measure. Overall engagement in psychological interventions was modest: 71 (76 %) of participants randomized to psycho-education attended at least one counselling session, and 21 (23 %) attended all six sessions. The Median number of sessions was 2. All patients reduced drug and alcohol problems at 9 months with small within-group effect sizes. Intention-to-treat analyses indicated significant differences between ILC and TAU in mean drugs composite score (p = .018) and in PDA (p = .041) at 3 months. Aggression declined in both groups, but no differences between ILC and TAU were observed in terms of alcohol problems or aggression at any follow-up. Moderate short-term improvements in substance use were associated with randomization to Impulsive Lifestyle Counselling. The findings support the usefulness of providing psycho-education to outpatients with antisocial personality disorder. ISRCTN registry, ISRCTN67266318 , 17/7/2012.

Genetic and Psychosocial Predictors of Aggression: Variable Selection and Model Building With Component-Wise Gradient Boosting.

Rationale : Given datasets with a large or diverse set of predictors of aggression, machine learning (ML) provides efficient tools for identifying the most salient variables and building a parsimonious statistical model. ML techniques permit efficient exploration of data, have not been widely used in aggression research, and may have utility for those seeking prediction of aggressive behavior. Objectives : The present study examined predictors of aggression and constructed an optimized model using ML techniques. Predictors were derived from a dataset that included demographic, psychometric and genetic predictors, specifically FK506 binding protein 5 (FKBP5) polymorphisms, which have been shown to alter response to threatening stimuli, but have not been tested as predictors of aggressive behavior in adults. Methods : The data analysis approach utilized component-wise gradient boosting and model reduction via backward elimination to: (a) select variables from an initial set of 20 to build a model of trait aggression; and then (b) reduce that model to maximize parsimony and generalizability. Results : From a dataset of N = 47 participants, component-wise gradient boosting selected 8 of 20 possible predictors to model Buss-Perry Aggression Questionnaire (BPAQ) total score, with R 2 = 0.66. This model was simplified using backward elimination, retaining six predictors: smoking status, psychopathy (interpersonal manipulation and callous affect), childhood trauma (physical abuse and neglect), and the FKBP5_13 gene (rs1360780). The six-factor model approximated the initial eight-factor model at 99.4% of R 2 . Conclusions : Using an inductive data science approach, the gradient boosting model identified predictors consistent with previous experimental work in aggression; specifically psychopathy and trauma exposure. Additionally, allelic variants in FKBP5 were identified for the first time, but the relatively small sample size limits generality of results and calls for replication. This approach provides utility for the prediction of aggression behavior, particularly in the context of large multivariate datasets.

Digit ratio (2D:4D) is a putative marker for prenatal testosterone and is correlated with performance in many sports. Low 2D:4D has been linked to strength but the evidence is mixed and strength is also influenced by mass, testosterone, and behavioural factors. It has been hypothesised that the 2D:4D-strength correlation may be strongest in challenge conditions when short-term changes occur in steroid hormones. We tested this suggestion in men. We used a cross-over study design with a challenge (an aggressive video of rugby tackles) and control (a blank screen) condition. 89 healthy men. Finger lengths (2nd and 4th for both hands), hand-grip strength (HGS), testosterone (T), cortisol (C), aggression (Buss-Perry Aggression Questionnaire) and personality type (Ten Item Personality Measure). In both conditions participants provided saliva samples (for hormone assays). In the challenge condition there was a highly significant increase in HGS, and modest changes in T, physical aggression and emotional stability. HGS correlated negatively with left hand 2D:4D. In a multiple regression, left hand 2D:4D was negatively related to HGS and emotional stability was positively related to HGS. In the control condition HGS was not correlated with 2D:4D. In a multiple regression, BMI, physical aggression, and emotional stability were significantly related to HGS. 2D:4D is a negative correlate of strength in challenge situations. This finding may in part explain associations between 2D:4D and sports performance. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The main enzyme for serotonin degradation, monoamine oxidase (MAO) A, has recently emerged as a key biological factor in the predisposition to impulsive aggression. Male carriers of low-activity variants of the main functional polymorphism of the MAOA gene (MAOA-uVNTR) have been shown to exhibit a greater proclivity to engage in violent acts. Thus, we hypothesized that low-activity MAOA-uVNTR alleles may be associated with a higher risk for criminal violence among male offenders. To test this possibility, we analyzed the MAOA-uVNTR variants of violent (n=49) and non-violent (n=40) male Caucasian and African-American convicts in a correctional facility. All participants were also tested with the Childhood Trauma Questionnaire (CTQ), Barratt Impulsivity Scale (BIS-11) and Buss-Perry Aggression Questionnaire (BPAQ) to assess their levels of childhood trauma exposure, impulsivity and aggression, respectively. Our results revealed a robust (P<0.0001) association between low-activity MAOA-uVNTR alleles and violent crime. This association was replicated in the group of Caucasian violent offenders (P<0.01), but reached only a marginal trend (P=0.08) in their African American counterparts. While violent crime charges were not associated with CTQ, BIS-11 and BPAQ scores, carriers of low-activity alleles exhibited a mild, yet significant (P<0.05) increase in BIS-11 total and attentional-impulsiveness scores. In summary, these findings support the role of MAOA gene as a prominent genetic determinant for criminal violence. Further studies are required to confirm these results in larger samples of inmates and evaluate potential interactions between MAOA alleles and environmental vulnerability factors. PMID:25082653

Controversy exists regarding the similarity between depression as seen in patients with epilepsy and in those with idiopathic major depression. The objective of this study was to examine whether anger is a distinctive feature of depression in epilepsy. Participants included 487 adult patients with epilepsy (study group) and 85 patients with idiopathic major depression according to Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) criteria, and without other neurological complications (control group). All participants completed the Inventory of Depressive Symptomatology Self-Report (IDS-SR) and the Buss-Perry Aggression Questionnaire (BAQ). The IDS-SR is a self-report questionnaire that measures depression severity and assesses all symptoms of depression as defined by the DSM-IV. The BAQ is a self-rating scale designed for assessing aggression. After examining potential confounding factors (i.e., demographic and clinical variables) using a multivariate linear regression model, BAQ scores were compared between the study (n = 85) and control groups (n = 54) for patients with moderate or severe depression using established cut-off points (IDS-SR score > 25). BAQ scores were significantly higher in the study group (P = 0.009). Among the BAQ subscales, only anger showed a statistically significant difference (P = 0.013). Although a significant correlation was revealed between the IDS-SR and BAQ scores in the study group, no such correlation was found in the control group. Thus, anger might be a constituent component of depression among epilepsy patients, but not among idiopathic major depression patients.

The primary objective of this study was to determine if second-generation antipsychotic (SGA) administration was associated with lower aggressiveness scores compared to first-generation (FGA) in schizophrenia (SZ). The secondary objective was to determine if antidepressants, mood stabilizers, and benzodiazepines administration were respectively associated with lower aggressiveness scores compared to patients who were not administered these medications. Three hundred thirty-one patients with schizophrenia (N = 255) or schizoaffective disorder (N = 76) (mean age = 32.5 years, 75.5 % male gender) were systematically included in the network of FondaMental Expert Center for Schizophrenia and assessed with the structured clinical interview for DSM-IV Axis I disorders and validated scales for psychotic symptomatology, insight, and compliance. Aggressiveness was measured by the Buss-Perry Aggression Questionnaire (BPAQ) score. Ongoing psychotropic treatment was recorded. Patients who received SGA had lower BPAQ scores than patients who did not (p = 0.01). More specifically, these patients had lower physical and verbal aggression scores. On the contrary, patients who received benzodiazepines had higher BPAQ scores than patients who did not (p = 0.04). No significant difference was found between BPAQ scores of patients respectively being administered mood stabilizers (including valproate), antidepressant, and the patients who were not. These results were found independently of socio-demographical variables, psychotic symptomatology, insight, compliance into treatment, daily-administered antipsychotic dose, the way of antipsychotic administration (oral vs long acting), current alcohol disorder, and daily cannabis consumption. The results of the present study are in favor of the choice of SGA in SZ patients with aggressiveness, but these results need further investigation in longitudinal studies. Given the potent side effects of benzodiazepines (especially dependency and cognitive impairment) and the results of the present study, their long-term prescription is not recommended in patients with schizophrenia and aggressive behavior.

Using a sample of 116 Japanese men who had been placed under parole/probationary supervision or released from prison, the present study examined standardization, reliability, and validation of the Japanese Criminal Thinking Inventory (JCTI) that was based on the short form of the Psychological Inventory of Criminal Thinking Styles (PICTS), a self-rating instrument designed to evaluate cognitive patterns specific to criminal conduct. An exploratory factor analysis revealed that four dimensions adequately captured the structure of the JCTI, and the resultant 17-item JCTI demonstrated high internal consistency. Compared with the Japanese version of the Buss-Perry Aggression Questionnaire (BAQ), the JCTI showed a favorable pattern of criterion-related validity. Prior criminal environment and drug abuse as the most recent offense also significantly correlated with the JCTI total score. Overall, the JCTI possesses an important implication for offender rehabilitation as it identifies relevant cognitive targets and assesses offender progress. © The Author(s) 2014.

The link between depression and aggressive behavior in adults has been found in many studies. In adolescents, this relationship is still controversial. Several studies point out that irritability is a key symptom in adolescent depressed. Few studies have analyzed precisely the kind of aggressive behavior. This study sets out to assess the relationship between aggressive behavior and depressive affects in adolescents. We also pay attention in this population to hopelessness feelings, anxiety, global functioning and the type of aggressive behavior. This is a descriptive and observational cross-sectional study. Data was collected from 49 successive adolescents admitted for a 24-hour evaluation in the emergency department of the Sainte-Anne psychiatric hospital. The inclusion period was from February to April 2012, with age limits between 15 and 18. For each patient, the clinician completed with the parents or other caregivers the Modified Overt Aggressive Scale (MOAS) searching for existence of aggressive behavior in the week prior to the consultation. The population was divided into two groups: P- group when the MOAS score was < 3 and the P+ group when the MOAS score was ≥ 3. The Global Assessment of Functioning Scale and Adolescent Depression Rating Scale for clinicians (ADRSc) were also completed. Each patient completed the self-report Buss-Perry Aggression Questionnaire (QA), the Beck Hopelessness scale and the Adolescent Depression Rating Scale for patients (ADRSp). Forty-nine adolescents with a median age of 16 years and 4 months participated. The first reason for consultation was depressive symptoms, followed by disruptive behavior. The analysis was conducted on 39 questionnaires. The demographic profile of the two groups was similar. We did not find any significant difference between the groups P+ and P- on ADRSc scores and secondary criteria. However, we found higher scores in the QA in the more depressed patient, especially a higher hostility score in this sample. In the subgroup analysis: as expected self-aggressive behavior was associated with a higher depression score, more hospitalization and a poor global functioning score. Surprisingly, the patients who showed physical aggression against others had a better prognosis and lower depression scores. The study did not conclude on the link between aggressive behavior and depression in this population. The adolescent hostility appears more characteristic of depression compared to other dimensions of aggressivity (anger, verbal aggression, physical aggression) in adolescents. Physical aggression against others appeared not only less typical in depression but was also associated with a better global functioning. Clinicians should pay particular attention to the kind of aggressive behavior in clinical evaluations of adolescents in an emergency context. Copyright © 2014 L’Encéphale, Paris.

Aggressiveness has been considered a peculiar feature of dreams associated with RBD, despite normal score in aggressiveness scales during wakefulness. We aimed to measure daytime aggressiveness and analyze dream contents in a population of patients with Parkinson disease (PD) with and without RBD. Design: This is a single-center prospective observational study; it concerns the description of the clinical features of a medical disorder in a case series. Setting: The study was performed in the Department of Neurosciences of the Catholic University in Rome, Italy. Patients: Three groups of subjects were enrolled: patients with PD plus RBD, patients with PD without RBD, and healthy controls. Interventions: The diagnosis of RBD was determined clinically and confirmed by means of overnight, laboratory-based video-polysomnography. For the evaluation of diurnal aggressiveness, the Buss-Perry Aggression Questionnaire (BPAQ) was used. The content of dreams was evaluated by means of the methods of Hall and Van De Castle. Measurements and Results: Patients with PD without RBD displayed higher levels of anger, and verbal and physical aggressiveness than patients with PD and RBD and controls. Patients with PD and RBD and controls did not differ in hostility. Conclusions: It can be hypothesized that a noradrenergic impairment at the level of the locus coeruleus could, at the same time, explain the presence of REM sleep behavior disorder, as well as the reduction of diurnal aggressiveness. This finding also suggests a role for REM sleep in regulating homeostasis of emotional brain function.

Explore relationships among traumatic brain injury (TBI), substance misuse and other mental health disorders in US service members and to identify risk factors for substance misuse. Service members (n = 93 in final sample) injured while deployed to Operation Enduring Freedom or Operation Iraqi Freedom. Longitudinal survey at 6 and 12 months post-intake. The following measures were used: problem substance use, Alcohol Expectancies Questionnaire-III, MINI International Neuropsychiatric Interview Substance Abuse Modules, Ohio State University TBI Identification Method, Neurobehavioural Symptom Inventory, Rivermead Post-Concussion Symptoms Questionnaire, Buss-Perry Aggression Questionnaire, Post-Traumatic Stress Disorder Checklist-Civilian Version, Beck Depression Inventory-II, Beck Anxiety Inventory. More severe TBI and post-traumatic stress disorder (PTSD) symptoms at 6 months post-enrolment were associated with decreased odds of substance misuse 12 months after study enrolment. Alcohol expectancies and incurring a TBI at a younger age increased the odds of substance misuse. While the ability to generalize the current findings to a larger population is limited, the results provide direction for future studies on the prevention and treatment of substance misuse following TBI. The unexpected protective effect of more severe TBI may result from prospective attention to the injury and its consequences. Greater preventive benefit may result from identifying more service members with elevated risk. Lifetime history of TBI and alcohol expectancies may be candidate indicators for greater attention.

Current knowledge on genetic basis of aggressive behavior is still contradictory. This may be due to the fact that the majority of studies targeting associations between candidate genes and aggression are conducted on industrial societies and mainly dealing with various types of psychopathology and disorders. Because of that, our study was carried on healthy adult individuals of both sex (n = 853). Three populations were examined: two traditional (Hadza and Datoga) and one industrial (Russians), and the association of aggression with the following polymorphisms 5-HTTLPR, rs6295 (5HTR1A gene), and rs6311 (5HTR2A gene) were tested. Aggression was measured as total self-ratings on Buss-Perry Aggression Questionnaire. Distributions of allelic frequencies of 5-HTTLPR and 5HTR1A polymorphisms were significantly different among the three populations. Consequently, the association analyses for these two candidate genes were carried out separately for each population, while for the 5HTR2A polymorphism, it was conducted on the pooled data that made possible to introduce ethnic factor in the ANOVA model. The traditional biometrical approach revealed no sex differences in total aggression in all three samples. The three-way ANOVA (μ + 5-HTTLPR + 5HTR1A + 5HTR2A +ε) with measures of self-reported total aggression as dependent variable revealed significant effect of the second serotonin receptor gene polymorphism for the Hadza sample. For the Datoga, the interaction effect between 5-HTTLPR and 5HTR1A was significant. No significant effects of the used polymorphisms were obtained for Russians. The results of two-way ANOVA with ethnicity and the 5HTR2A polymorphism as main effects and their interactions revealed the highly significant effect of ethnicity, 5HTR2A polymorphism, and their interaction on total aggression. Our data provided obvious confirmation for the necessity to consider the population origin, as well as cultural background of tested individuals, while searching for associations between genes and behavior, and demonstrated the role of cultural attitudes towards the use of in-group aggression. Our data partly explained the reasons for disagreement in results of different teams, searching for candidate-gene associations with behavior without considerations of culturally desirable norms. Previous studies suggested that the 5HTR2A gene polymorphism associates with aggression and criminality. Our data extended these findings, demonstrating the role of rs6311 (5HTR2A gene) in aggression in adult healthy men and women from our samples. We found that G-allele carriers were rated higher on total aggression.

To determine the factors involved in violent behavior in patients with bipolar disorder (BD) and to investigate the relationship between violence and substance use disorder (SUD). A sample of 100 male inpatients diagnosed with BD type I who were experiencing a current mood episode participated in the study. Violent behavior was defined as physical aggression against others. All patients were evaluated using the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HDRS), Positive and Negative Syndrome Scale-positive subscale (PANSS-p), Barratt Impulsivity Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BPAQ) and Overt Aggression Scale (OAS). Lifetime SUD and current use of substances were evaluated. Logistic regression analysis was conducted to predict violent behavior. Current substance use (CSU) rather than lifetime SUD was found to be related to violent behavior in patients with BD, and CSU was associated with a threefold increase in the risk of violence. The rate of lifetime SUD in our sample was 59%, and the rate of CSU was 39%. The most commonly abused substances were cannabis and alcohol, followed by synthetic cannabinoids, in both groups of patients with lifetime SUD and CSU. Individuals abusing any substance were more likely to have a criminal record and history of incarceration than other patients. One of the most significant risk factors for violence was a previous history of violent behavior. The sample was limited to male patients. Data on some participants' recent substance use from standard urine analysis was not obtained. The data on the use of synthetic cannabinoids was obtained from patients and their families owing to the lack of equipment for detecting synthetic cannabinoids using laboratory analysis. CSU appears to be a significant predictive factor in violent behavior in male patients. Further investigation of co-occurrence of violence with CSU and improvement in treatment strategies might reduce or prevent violence in patients with BD. Copyright © 2015 Elsevier B.V.

We aimed to investigate the predictive factors of violent behavior in schizophrenia and the relationship between violent behavior and insight and cognitive functions in this study. 68 patients diagnosed with schizophrenia were separated into two groups; with a history of violent behavior (n = 30) and without (n = 38). Both group swere administered the Positiveand Negative Syndrome Scale (PANSS), Buss-Perry Aggression Questionnaire, Schedule for Assessing the Three Components of Insight, California Verbal Learning Test (CVLT), Trail Making Test, Wisconsin Card Sorting Test, and Stroop Test. Male gender, the number of hospitalizations, incompliance with the treatment, alcohol and substance abuse, the number of suicide attempts, the mean score of PANSS positive symptoms, PANSS general symptoms and PANSS total were significantly higher in patients with schizophrenia with a history of violent behavior, compared to non-violent group. Long delayed response subsection of CVLT mean score was lower in patients with violent behavior. Incompliance with the treatment (OR:5.927, p=0.041), alcohol and substance abuse (OR:21.089, p=0.000), and PANSS total score (OR:1.053, p=0.011)were identified as predictive factors of violent behavior in patients with schizophrenia. Lack of insight and executive function impairment are the core symptoms of schizophrenia and not seems to be associated with violent behavior in patients with schizophrenia. Impairment of memory may be associated with violent behavior in patients with schizophrenia. Incompliance with treatment, alcohol and substance abuse, and the severity of positive symptoms are important factors in predicting violence behavior in patients with schizophrenia.

Hoarseness is most frequent complaint notified by ill in phoniatric outpatient clinics. Looking of causes notified of disturbances of voice often we ascertain in larynx existence of vocal nodules. Changes these come into being in consequence of excessive or irregular phonations. Single incident of disturbances of voice caused with oedema changes nascent of in consequence of inappropriate work with voice does not wake of our trouble, instead returns this of type of complaint provoke to other researches coexisting of etiological factors this diseases. Estimation of influence of individual personality trait of ill on formation of vocal nodules. One examined 20 patients with vocal nodules classified to treatments operating and 20 without disturbances of voice. All patients were subjected to otolaryngological and stroboscopic examinations. Character created of voice one examined at help of scale GRBAS, instead influence of disturbances of voice on quality of life ill at help of test VHI. Psychological examinations one executed using questionnaire State-Trait-Anxiety-Inventory (STAI), questionnaire NEO-FFI and questionnaire of aggression Buss-Perry. Obtained results showed, that persons with returning vocal nodules, both during of research as in different situations everyday lives characterizes with higher level of fear and have greater inclination to worry oneself. Ill from groups examined in greater degree are extroverts, show greater activity and more are contagious socially in comparison to persons of comparative group. Attitude this in situations extorting rivalry will be able to be ruthless, are well organized guided, scrupulous and consistently endeavour to aim. Wanting efficiently to treat persons with returning vocal nodules we should subject to ill psychological examination and in once of ascertainment of irregularity to correct it, what at simultaneous correct treatment of organic changes should diminish frequency or to eliminate returns of disease. Skill psychological looks on patient by therapists treating disturbances of voice and speeches in case not large emotional instabilities probably would be able to improve results of treatment ill not only with functional disturbances of voice but also with disturbances of voice caused with organic changes in larynx.

Aggression in online contexts has received much attention over the last decade, yet there is a need for measures identifying the proximal psychological drivers of cyber-aggressive behavior. The purpose of this study was to present data on the newly developed Cyber-Aggression Typology Questionnaire (CATQ) designed to distinguish between four distinct types of cyber-aggression on dimensions of motivational valence and self-control. A sample 314 undergraduate students participated in the study. The results confirmed the predicted four-factor structure providing evidence for distinct and independent impulsive-aversive, controlled-aversive, impulsive-appetitive, and controlled-appetitive cyber-aggression types. Further analyses with the Berlin Cyberbullying Questionnaire, Reactive Proactive Aggression Questionnaire, and the Behavior Inhibition and Activation Systems Scale provide support for convergent and divergent validity. Understanding the motivations facilitating cyber-aggressive behavior could aid researchers in the development of new prevention and intervention strategies that focus on individual differences in maladaptive proximal drivers of aggression.

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. © 2018 Wiley Periodicals, Inc.

Telomere shortening, a marker of cellular aging, has been considered to be linked with psychosocial stress as well as with chronic alcohol consumption, possibly mediated by oxidative stress and inflammatory response. Recent findings suggested that early life adversity on telomere dynamics may be related to impulsive choice. To further our understanding of the association of impulsive choice and childhood trauma on telomere length, we examined whether delayed discounting and childhood trauma or their interaction is related to leukocyte telomere length, while controlling for multiple potential confounding variables, in patients with alcohol dependence who are considered to have higher impulsive choice and shorter telomere length. We recruited 253 male patients with chronic alcohol dependence. All participants performed the delay discounting task, and the area under curve was used as a measure of delay discounting. Steeper delay discounting represents more impulsive choices. The modified Parent-Child Conflict Tactics Scale was used to measure childhood maltreatment. In addition, confounding factors, including socio-demographic characteristics, the Alcohol Use Disorders Identification Test, the Buss-Perry Aggression Questionnaire, the Resilience Quotient, the Beck Depression Inventory, and the Beck Anxiety Inventory, were also assessed. Hierarchical regression analyses showed a significant main effect of delay discounting (β=0.161, t=2.640, p=0.009), and an interaction effect between delay discounting and childhood maltreatment on leukocyte telomere length (β=0.173, t=2.138, p=0.034). In subsequent analyses stratified by childhood maltreatment, patients with alcohol dependence and high childhood trauma showed a significant relationship between delay discounting and leukocyte telomere length (β=0.279, t=3.183, p=0.002), while those with low trauma showed no association between them. Our findings suggest that higher impulsive choice is associated with shorter telomere length, and childhood trauma may exert a moderating effect in the relationship between impulsive choice and telomere length.

Aggression and anger have been linked with depression, and anger suppression has been linked with somatic symptoms of somatoform disorders. However, the relationship between aggression or anger and genes in patients with depression and somatoform disorders has not been clearly elucidated. The objective of this study was to examine the effect of serotonin-related gene polymorphism on aggression in depressive disorders and somatoform disorders. A serotonin-related polymorphic marker was assessed by using single nucleotide polymorphism (SNP) genotyping. 106 outpatients with major depressive disorder (MDD), 102 outpatients with undifferentiated somatoform disorder, and 133 healthy subjects were enrolled between October 2005 and May 2008. Diagnoses were made according to the Korean version of the Structured Clinical Interview Schedule for DSM-IV. The allele and genotype frequencies of tryptophan hydroxylase-1 (TPH1) A218C were compared between groups. The Hamilton Depression Rating Scale and the Aggression Questionnaire were used for psychological assessment. Each of the 2 disorder groups scored significantly higher on all the Aggression Questionnaire subscales and on the total Aggression Questionnaire score than the healthy subjects (P < .001). Patients with MDD had significantly higher frequencies of TPH1 C allele (P = .0002) and CC homozygote (P = .0003) than healthy subjects, regardless of sex and age. However, no significant differences were found in TPH1 C allele and CC homozygote frequencies between the undifferentiated somatoform disorder patients and the healthy subjects. TPH1 CC homozygote in the MDD group scored significantly higher in terms of verbal aggression (P = .03) and total Aggression Questionnaire score (P = .04) than A-carrier genotypes, regardless of sex and age. However, no significant differences were found in the scores of all the Aggression Questionnaire subscales and the total Aggression Questionnaire score between TPH1 CC homozygote and A-carrier genotypes in the undifferentiated somatoform disorder group and the control group, respectively. Aggression in MDD patients is more susceptible to an excess of TPH1 CC homozygote than in undifferentiated somatoform disorder patients, though the 2 disorders are high risk groups for aggression. In addition, TPH1 gene is most likely to have a shared effect on aggression and MDD. © Copyright 2012 Physicians Postgraduate Press, Inc.

Patient initiated aggression toward general practice staff can cause distress among staff, however, it is unknown how frequently practice staff experience patient aggression in the workplace. The aim of this study is to determine the national prevalence of patient aggression toward general practice staff. A clustered cross sectional survey involving general practice staff working in Australia. A questionnaire was posted to 1109 general practices nationally and 217 questionnaires were completed and returned (19.6% response rate). It was found that verbal aggression is commonly experienced by practice staff, particularly receptionists, whereas physical aggression is infrequent. Staff working in larger practices experience more verbal aggression and property damage or theft and it was reported that verbal aggression has a greater impact on staff wellbeing than physical aggression. This study provides some national evidence of the prevalence of patient aggression toward general practice staff. This may inform the development of policy and procedures.

Excessive aggression is a common behaviour problem in dogs that can have various destructive effects on the affected people and the implicated dog. Aggressive behaviour directed towards the owner or other family members is one of the most frequently occurring aggressive phenotypes. Here, we examine the reliability of a short questionnaire assessing aggressive behaviours by two, contextually different behavioural tests: 'take away bone' and 'roll over'. Based on dogs' behaviour in the tests, we sorted dogs ( N  = 93) in two groups for each test, namely a less and a more disobedient/resistant group. The two principal components obtained in our questionnaire-'obedient' and 'aggressive towards owner'-showed significant differences between the behaviour groups. While dogs in the less disobedient/resistant groups had significantly higher 'obedient' and significantly lower 'aggressive towards owner' scores, dogs in the more disobedient/resistant groups had significantly higher 'aggressive towards owner' and significantly lower 'obedient' scores. Dogs' age, sex and neuter/spay status expressed their effect through interactions. Males, young dogs and intact dogs were less 'obedient' than older ones, while resistant spayed/neutered dogs were more aggressive towards the owner. The questionnaire used is a safe, easy to deploy and time-efficient tool to reliably assess certain owner-directed aggressive tendencies of family dogs.

Some situations require psychiatric staff nurses to respond to service users' negativity or aggression. As a result, psychiatric staff nurses may experience anger. The current study examined how anger levels of psychiatric staff nurses triggered by anger-generating situations by service users affected nurses' confidence and attitudes. A questionnaire survey was administered among 386 psychiatric staff nurses. The questionnaire surveyed anger levels in anger-generating situations, aggressiveness, nurses' attitudes toward aggression, and self-efficacy of intervening in aggressive situations. Path analysis revealed differences between male and female nurses. Male nurses' anger in response to physical aggression was mild when they were confident in handling aggression. Furthermore, female nurses who had high confidence in intervening in an aggressive situation had low anger levels. Confidence in intervening in aggressive situations appeared to dissipate anger and ease nurses during aggressive interactions.

Aggressive behavior and violence directed by patients at nurses are increasing worldwide. Aggressive behavior against nurses in their workplace can result in personal problems, such as impairment of physical and mental well-being, and, consequently, in organizational problems. Underreporting of patients' aggressive behavior is prevalent among nurses. Although underreporting might lead to inefficient attention to strategies for preventing aggressive behavior, the reasons for such behavior not being reported frequently have not been well examined. To explore the frequency of nurses' reporting to their managers of patients' aggressive behavior by type and degree of impact suffered by the nurses, to examine the association between reporting of aggressive behavior and demographic factors, and to determine the reasons for underreporting. A questionnaire-based cross-sectional survey. Six acute care hospitals in two regions in Japan. A total of 1953 nurses working at general acute care hospitals participated. Data were collected through a questionnaire seeking sociodemographic information, information on experience of aggressive behavior from patients, and the frequency with which they had reported such behavior in the previous month. The questionnaire also contained items assessing barriers to reporting of patients' aggressive behavior. The association between the possible influencing factors and reporting behavior was assessed using multiple logistic regression analyses. Of the 1953 questionnaires distributed, 1498 (76.7%) were returned, and 1385 (70.9%) fully completed questionnaires were analyzed. More than one-third of the respondents had experienced the mildest assessed level of impact from patients' aggressive behavior, and 70% of those hardly reported any incidents. The milder the impact was, the less the nurse victims tended to report the incident. Nurse's tendency to feel that aggressive behavior was mitigated by the situation, less work experience, and lack of confidence that management would defend staff nurses from patients' aggressive behavior were found to be negatively associated with reporting behavior. This study identified factors associated with nurses' reporting of patients' aggressive behavior. Underreporting was found to be associated with the level of impact, managerial attitudes, nurses' work experience, and nurses' perception that the behavior was mitigated by the situation. Improving education among nurses to promote reporting incidents and establishing an organized system is needed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Prevalence and clinical correlates of intermittent explosive disorder in Turkish psychiatric outpatients.

Intermittent explosive disorder (IED) is defined as the failure to resist aggressive impulses resulting in repeated acts of verbal and/or physical aggression. Although it is frequently encountered in clinical psychiatric practice, there is a paucity of data concerning IED in the scientific literature both internationally and in Turkey. The aim of this study was to evaluate the prevalence of IED and associated sociodemographic and clinical features in a clinical setting. A total of 406 patients who were referred to our psychiatry outpatient clinic for the first time in a six-month period were included in the study. The diagnosis of IED was made using both Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) and DSM-5 criteria. Axis I disorder and personality disorder diagnoses were made according to DSM-5 criteria. Diagnoses were based on information from the Structured Clinical Interview for DSM-IV (SCID I) and the Structured Clinical Interview for DSM-IV personality disorders (SCID II), Symptom Checklist-90 (SCL-90), Wender Utah Rating Scale, Adult Attention Deficit Hyperactivity Disorder (ADHD) DSM-IV Based Diagnostic Screening and Rating Scale, a clinical interview conducted by the researcher, and a sociodemographic data form. In addition, participants were administered the Buss-Perry Aggression Scale and Barratt Impulsiveness Scale Version 11 (BIS-11) to assess aggression and impulsivity. Lifetime and 12-month prevalence of IED according to DSM-5 were 16.7% and 11.3%, respectively. Mean age at onset was 16.4 years. The prevalence of lifetime IED was 3.8 times higher in males than females (95% CI = 1.9-7.5); twice as high in individuals living in rural areas compared to those living in urban centers (95% CI = 1.1-3.7); 2.7 times higher among those with lifetime suicide attempt versus those without (95% CI = 1.3-5.6); 4.5 times higher in those with lifetime self-injurious behavior compared to those without (95% CI = 2.3-8.7); and 3 times higher in individuals reporting aggression/anger problems in the family compared to those without (95% CI = 1.5-5.9). The prevalences of childhood ADHD, conduct disorder, and oppositional defiant disorder were significantly higher in the IED group. The result of the current study has revealed that approximately one-sixth of respondents experienced lifetime IED according to DSM-5 diagnostic criteria. Statistically significant sociodemographic correlates of IED include gender, urbanicity, history of suicide attempt, history of self-injurious behavior, and family history of aggression/anger problems.

For thousands of years it has been known that aggression as a symptom appears in numerous psychiatric disorders and diseases. During the last decade the appearance of the aggressive behavior related to the posttraumatic stress disorder (PTSD) has been frequently investigated, often associated with war trauma. The goal of this study is to analyze the impact of alcoholism on a way war veterans suffering from chronic PTSD express and control aggression. The sample included 240 war veterans with chronic PTSD. The subjects were divided in two groups. PTSD group (n=147) and controlled group composed of those suffering from alcoholism in addition to PTSD (n=93). In this study, the following psychological instruments were used: The Harvard trauma questionnaire for PTSD diagnosis (HTQ); the questionnaire for self-evaluation of aggression (STAXI); The Profile Index Emotion (PIE); questionnaire for auto-diagnosis of alcoholism (CAGE). The obtained results indicate that subjects who have PTSD with co-morbid alcoholism are more deprived, aggressive (p < 0.001) and oppositional (p < 0.05) in comparison to subjects whose PTSD is not combined with alcoholism (PIE). The aggression is statistically more expressed in subjects with PTSD who have also been diagnosed with alcoholism on all subscales in comparison to subjects with PTDS who have not been diagnosed with alcoholism: the current state of aggression, the general state of aggression, aggression towards an unfair treatment, aggression directed inwards and outwards (p < 0.001); aggression towards nonspecific provocation and a general way of expressing aggression (p < 0.05) (STAXI). Subjects that had PTSD combined with alcoholism show a higher degree of aggression in comparison to subjects with PTDS who are not diagnosed with alcoholism.

The paper addresses the issue of violence among correctional officers. The aim of the study was to assess the frequency of exposure to violence in this professional group. The study comprised the sample of 222 correctional officers who voluntary and anonymously fulfilled the MDM questionnaire. The MDM Questionnaire allows for assessing exposure to aggression and mobbing at work. Preliminary assessment of exposure to single aggressive acts and mobbing shows a quite alarming tendency--around one third of subjects under the study experienced repetitive aggressive acts from coworkers and/or superiors. The problem of organizational aggression in correctional institutions should be recognized in details to develop effective preventive measures against violent behaviors occurring at work.

A maternal authoritarian style has been related to the development of physical aggression during childhood and later future social problems; however, not too many studies have detected other than individual or family factors that may buffer this maternal effect. This work examines whether daycare center attendance may moderate the relationships between a mother authoritarian style and physical aggression. The study sample was 72 (40 girls) kindergarten children from Spain. Parents were asked to complete two questionnaires focused on individual family characteristics and parenting styles. At age 5, children physical aggression was assessed by direct observation at playtime; aggression scores at 6 was obtained by a peer-rated questionnaire. A least squared multiple regression was performed after controlling for children’s level of physical aggression at 5, child sex and siblings. A positive contribution of maternal authoritarian style on physical aggression was detected. Daycare center attendance appears to attenuate the effect of the mother’s authoritarian style on physical aggression, only in boys. PMID:28377733

A maternal authoritarian style has been related to the development of physical aggression during childhood and later future social problems; however, not too many studies have detected other than individual or family factors that may buffer this maternal effect. This work examines whether daycare center attendance may moderate the relationships between a mother authoritarian style and physical aggression. The study sample was 72 (40 girls) kindergarten children from Spain. Parents were asked to complete two questionnaires focused on individual family characteristics and parenting styles. At age 5, children physical aggression was assessed by direct observation at playtime; aggression scores at 6 was obtained by a peer-rated questionnaire. A least squared multiple regression was performed after controlling for children's level of physical aggression at 5, child sex and siblings. A positive contribution of maternal authoritarian style on physical aggression was detected. Daycare center attendance appears to attenuate the effect of the mother's authoritarian style on physical aggression, only in boys.

This study compares adults with and without attention deficit hyperactivity disorder (ADHD) on measures of direct and displaced aggression and illicit drug use. Three hundred ninety-six adults were administered the Wender Utah Rating Scale, the Risk Behavior Assessment, the Aggression Questionnaire (AQ), and the Displaced Aggression Questionnaire (DAQ). Those with ADHD were higher on all scales of the AQ and DAQ, were younger at first use of amphetamines, and were more likely to have ever used crack and amphetamines. A Structural Equation Model found a significant interaction in that for those with medium and high levels of verbal aggression, ADHD predicts crack and amphetamine. Follow-up logistic regression models suggest that blacks self-medicate with crack and whites and Hispanics self-medicate with amphetamine when they have ADHD and verbal aggression.

Canine aggression is one of the most frequent problems in veterinary behavioral medicine, which in severe cases may result in relinquishment or euthanasia. As it is important to reveal underlying factors of aggression for both treatment and prevention, we recently developed a questionnaire on aggression and temperamental traits and found that “reactivity to stimuli” was associated with aggression toward owners, children, strangers, and other dogs of the Shiba Inu breed. In order to examine whether these associations were consistent in other breeds, we asked the owners of insured dogs of Anicom Insurance Inc. to complete our questionnaire. The top 17 contracted breeds were included. The questionnaire consisted of dogs' general information, four items related to aggression toward owners, children, strangers, and other dogs, and 20 other behavioral items. Aggression-related and behavioral items were rated on a five-point frequency scale. Valid responses (n = 5610) from owners of dogs aged 1 through 10 years were collected. Factor analyses on 18 behavioral items (response rate over 95%) extracted five largely consistent factors in 14 breeds: “sociability with humans,” “fear of sounds,” “chase proneness,” “reactivity to stimuli,” and “avoidance of aversive events.” By stepwise multiple regression analyses, using the Schwartz's Bayesian information criterion (BIC) method with aggression points as objective variables and general information and temperamental factor points as explanatory variables, “reactivity to stimuli,” i.e., physical reactivity to sudden movement or sound at home, was shown to be significantly associated with owner-directed aggression in 13 breeds, child-directed aggression in eight breeds, stranger-directed aggression in nine breeds, and dog-directed aggression in five breeds. These results suggest that “reactivity to stimuli” is simultaneously involved in several types of aggression. Therefore, it would be worth taking “reactivity to stimuli” into account in the treatment and prevention of canine aggression. PMID:24972077

It is still not clear what the unique contribution of particular psychopathological factors is in explaining aggression in schizophrenia. The current study examined whether persecutory ideations, psychopathy and substance use are associated with different measures of aggressive behavior. We expected that persecutory ideations are associated with reactive aggression, and psychopathic traits are more associated with proactive aggression of inpatients. 59 inpatients with schizophrenia were included. Persecutory ideations we assessed using the Persecutory Ideation Questionnaire (PIQ), psychopathic traits with the revised version of Psychopathic Personality Inventory (PPI-R) and substance use was assessed using the Comprehensive Assessment of Symptoms and History (CASH). In addition, aggression was measured with the Reactive and Proactive Aggression Questionnaire (RPQ), in an experimental task using the Point Subtraction Aggression Paradigm (PSAP) and on the ward using the Social Dysfunction and Aggression Scale (SDAS). Results showed that psychopathy explains most of the variance in self-reported proactive and reactive aggression. In contrast, persecutory ideations explain most of the variance in observed aggression on the ward. Results implicate that it is important to acknowledge comorbid factors in patients with schizophrenia for more precise risk assessment and appropriate treatment for aggressive patients with schizophrenia.

The aim of this research was to determine the relation between death attitude and distress tolerance and aggression and anger. For this, 135 subjects among 7,535 professional and specialist members of the Iran National Library were selected using convenience sampling method. They replied to Death Attitudes Profile-Revised, distress tolerance questionnaire, and aggression questionnaire. The results showed that the attitudes of approach acceptance, neutral acceptance, and escape acceptance had positive relation to distress tolerance and negative relation to aggression and anger while the attitudes of fear of death and death avoidance had negative relation to distress tolerance and positive relation to aggression and anger. Furthermore, all death attitudes predicted distress tolerance. But only the attitudes of approach acceptance, escape acceptance, fear of death, and death avoidance predicted aggression, and only approach acceptance, neutral acceptance, fear of death, and death avoidance predicted anger.

ABSTRACT Canine aggression is one of the behavioral problems for which veterinary behaviorists are most frequently consulted. Despite this, the classification of canine aggression is controversial, and there are several classification methodologies. While the etiology of canine aggression differs among the types of aggression, the behavioral background underlying aggression is not well understood. Behavior trait-based evaluation of canine aggression would improve the effectiveness and efficiency of managing canine aggression problems. We developed a questionnaire addressing 14 behavioral items and items related to four types of canine aggression (owner-, child-, stranger- and dog-directed aggression) in order to examine the associations between behavioral traits and aggression in Shiba Inu. A total of 400 Shiba Inu owners recruited through dog events (n=134) and veterinary hospitals (n=266) completed the questionnaire. Factor analysis sorted the behavioral items from both the event and clinic samples into four factors: “sociability with humans,” “reactivity to stimuli,” “chase proneness” and “fear of sounds.” While “reactivity to stimuli” correlated significantly positively with all of the four types of aggression (P=0.007 to <0.001), “sociability with humans” correlated significantly negatively with child- and stranger-directed aggression (P<0.001). These results suggest that the behavioral traits involved in canine aggression differ among the types of aggression and that specific behavioral traits are frequently simultaneously involved in several types of aggression.

Both attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are frequently accompanied by serious aggression that requires psychiatric treatment. However, little is known about the experiences psychiatrists have had using pharmacotherapy to treat aggression in patients who have both ASD and ADHD (ASD/ADHD). The purpose of this study was to examine the experiences of Japanese child and adolescent psychiatrists in prescribing medication for aggression in patients with ASD/ADHD. A prospective questionnaire was mailed to 2001 psychiatrists affiliated with the Japanese Society for Child and Adolescent Psychiatry. Multivariate logistic regression analysis was used to identify factors predicting the outcome of pharmacotherapeutic treatment of aggression in pediatric and adolescent patients with ASD/ADHD. Of 2001 psychiatrists, 571 (28.5%) completed the full questionnaire (final sample). Of these, 488 (85.4%) prescribed psychotropic medication in treating pediatric and adolescent patients with ASD/ADHD, 299 (61.3%) of them doing so to treat aggression. Prescribers' duration of practice (odds ratio, 1.055; P = 0.038) and patient symptoms of residual impulsivity (odds ratio, 2.479; P = 0.039) increased the odds of prescribing psychotropic medications to treat aggression in these patients. The respondents reported a similar effect for patients with ADHD/ASD compared with those with ADHD only in treating aggression. Japanese psychiatrists tended to prescribe psychotropic medication for aggression in pediatric and adolescent patients with ASD/ADHD. Future studies examining aggression in pediatric and adolescent patients with ASD/ADHD should aim to accumulate evidence for the use of psychotropic medications, which could help clinicians make better decisions. © 2017 The Authors.

This study reports the development of the Reactive–Proactive Aggression Questionnaire (RPQ), and the differential correlates of these two forms of aggression. Antisocial, psychosocial and personality measures were obtained at ages 7 and 16 years in schoolboys, while the RPQ was administered to 334 of the boys at age 16 years. Confirmatory factor analysis indicated a significant fit for a two-factor proactive–reactive model that replicated from one independent subsample to another. Proactive aggression was uniquely characterized at age 7 by initiation of fights, strong-arm tactics, delinquency, poor school motivation, poor peer relationships, single-parent status, psychosocial adversity, substance-abusing parents, and hyperactivity, and at age 16 by a psychopathic personality, blunted affect, delinquency, and serious violent offending. Reactive aggression was uniquely characterized at age 16 by impulsivity, hostility, social anxiety, lack of close friends, unusual perceptual experiences, and ideas of reference. Findings confirm and extend the differential correlates of proactive–reactive aggression, and demonstrate that this brief but reliable and valid self-report instrument can be used to assess proactive and reactive aggression in child and adolescent samples.

The present study explored whether aggression, emotional regulation, cognitive inhibition, and attentional bias towards emotional stimuli were related to risky driving behavior (driving errors, and driving violations). A total of 117 applicants for taxi driver positions (89% male, M age=36.59years, SD=9.39, age range 24-62years) participated in the study. Measures included the Ahwaz Aggression Inventory, the Difficulties in emotion regulation Questionnaire, the emotional Stroop task, the Go/No-go task, and the Driving Behavior Questionnaire. Correlation and regression analyses showed that aggression and emotional regulation predicted risky driving behavior. Difficulties in emotion regulation, the obstinacy and revengeful component of aggression, attentional bias toward emotional stimuli, and cognitive inhibition predicted driving errors. Aggression was the only significant predictive factor for driving violations. In conclusion, aggression and difficulties in regulating emotions may exacerbate risky driving behaviors. Deficits in cognitive inhibition and attentional bias toward negative emotional stimuli can increase driving errors. Predisposition to aggression has strong effect on making one vulnerable to violation of traffic rules and crashes. Copyright © 2017 Elsevier Ltd. All rights reserved.

2013-01-01

The relationship between the use of alcohol and aggression is complex and represents major public health issues. Delving into the nature of this association is vital, since various underlying factors may contribute to the expression of aggression. This study examined trait aggression by assessing correlates and, subsequently, the unique contribution of alcohol craving, and dysfunctional impulsivity, by means of correlational and mediational analyses. Forty inpatient detoxified alcohol-dependent patients were recruited. These participants completed the Desire for Alcohol Questionnaire (DAQ), Dickman Impulsivity Inventory (DII), and the Aggression Questionnaire (AQ). The findings indicated that aggression, dysfunctional impulsivity, and alcohol craving were all positively intercorrelated. The association between dysfunctional impulsivity and aggression was robust. The mediational analyses yielded that craving partially mediated this relationship, although not very substantial. It was shown that impulsivity, as a personality characteristic, is strongly associated with aggressive behaviors, whereby the impact of craving on the relationship between impulsivity and trait aggression in alcohol-dependent inpatients was weak. Since it has been posited that factors such as impulsivity and craving may contribute to the lucid association between substance use and aggression, these findings mirror previous research on stimulant users and, subsequently, substantiates that craving exerts only a minor weight on the strong impulsivity-aggression relationship.

To investigate the association of monoamine oxidase Agene polymorphisms with aggression. The study was conducted in an ethnic community in Lahore, Pakistan, from August 2008 to December 2009 on the basis of data that was collected through a questionnaire between August 2004 and September 2005. It analysed 10 single nucleotide polymorphisms of monoamine oxidase A in unrelated males from the same ethnic background who were administered a Punjabi translation of the Buss and Perry aggression questionnaire. SPSS 13 was used for statistical analysis. Of the total 133 haplotypes studied, 52(39%) were Haplotype A, 58(43.6%) B, 8(6%) C, 3(2.3%) D, 9(6.8%) E and 3(2.3%) F. The six haplotypes were analysed for association with scores of the four subscales of the aggression questionnaire and multivariate analysis of variance showed no significant differences (p>0.05 each) in the error variances of the total scores and scores for three of the sub-scales across the haplotypes. The variance was significantly different only for the anger sub-scale (p<0.05). The association of an extended haplotype with low levels of self-reported aggression in this study should assist in characterisation of functional variants responsible for non-aggressive behaviour in male subjects.

Sexual-perception processes in acquaintance-targeted sexual aggression.

Treat, Teresa A; Viken, Richard J

2018-05-01

This study analyzes data from seven published studies to examine whether three performance-based indices of men's misperception of women's sexual interest (MSI), derived from a self-report questionnaire, are associated with sexual-aggression history, rape-supportive attitudes, sociosexuality, problem drinking, and self-reported MSI. Almost 2000 undergraduate men judged the justifiability of a man's increasingly unwanted advances toward a woman on the Heterosocial Perception Survey-Revised. Participants self-reported any sexual-aggression history, and some completed questionnaires assessing rape-supportive attitudes, sociosexuality, problem drinking, and self-reported MSI. A three-parameter logistic function was fitted to participants' justifiability ratings within a non-linear mixed-effects framework, which provided precise participant-specific estimates of three sexual-perception processes (baseline justifiability, bias, and sensitivity). Sexual-aggression history and rape-supportive attitudes predicted: (a) reduced sensitivity to women's affect; (b) more liberal biases, such that the woman's affect had to be more negative before justifiability ratings dropped substantially; and (c) greater baseline justifiability of continued advances after a positive response. Sexual-aggression history and attitudes correlated more strongly with sensitivity than baseline justifiability; remaining variables showed the opposite pattern. This work underscores the role of sexual-perception processes in sexual aggression and illustrates the derivation of performance-based estimates of sexual-perception processes from questionnaire responses. © 2018 Wiley Periodicals, Inc.

Background Associations between early life maltreatment, social information processing (SIP) and aggression in childhood and adolescence have been widely documented. Few studies have examined the importance of childhood maltreatment independent of SIP in the etiology of adult aggression. Furthermore, moderating effects of childhood maltreatment on the SIP–aggression links have not been explored. Method Hierarchical, multi-level models were fitted to data from n=2752 twins aged 20–55 years from the PennTwins Cohort. Adult aggression was assessed with the Life History of Aggression questionnaire. Childhood maltreatment was measured using the Childhood Trauma Questionnaire. Two aspects of SIP were examined : hostile attribution biases (HAB) ; negative emotional responses (NER). Results Childhood maltreatment was positively correlated with adult aggression, independently of HAB and NER. In addition, childhood maltreatment moderated the relationships between both aspects of SIP and adult aggression. Specifically, the relationship between NER and aggression was stronger among individuals with higher levels of childhood maltreatment and NER was not associated with aggression for adults who experienced low levels of childhood maltreatment. Moderating effects of childhood maltreatment on the NER–aggression link were supported for total childhood maltreatment, emotional neglect and emotional abuse. In contrast, HAB was more strongly associated with adult aggression at lower levels of emotional abuse and physical neglect. Conclusions The current study provides insight into the mechanisms by which early life experiences influence adult aggression. Our findings suggest that childhood maltreatment may not only lead to increased levels of aggression in adulthood but may also modify the associations between SIP and adult aggression. PMID:22008562

Effect of motor limitations on the expression of aggressiveness among adolescents.

This study examined how motor limitations in terms of reduced possibilities to move influence aggression, starting from the fact that motor skills and movement have an important place in the expression of aggression, as well as the tendency of adolescents to "body language". Adolescent with motor deficit is hindered in gaining experience of one's own body, which is reflected in the formation of complete experience of himself, or constitution of the self. In many of the functions of motor skills and movement aggression has a significant place that we wanted to determine without deeper analysis of whether the origin of aggression is instinctive or it is always just the result of frustration. The sample on which testing was performed consisted of 100 randomly selected subjects of both genders aged 16-18 years. Fifty subjects had motor limitations due to illness or injury, and another fifty subjects had intact motor functions. The study used three instruments: 1) A-87 questionnaire for aggressiveness examination; 2) structured interview; and 3) protocol for observation under natural conditions. Results of the analysis of data obtained in total score, as well as in all five subscales of the A-87 questionnaire for aggressiveness examination showed that the two groups were not significantly different. The results obtained by structured interview showed the adolescents with motor limitations to demonstrate greater verbal aggressiveness, then latent physical aggressiveness. A statistically significant between-group difference was obtained on the factor of self-destructiveness, which implies that adolescents with motor limitations are somewhat more self-destructive compared to those in control group. From the results obtained by the protocol for systematic observation in natural conditions, it was evident that there were significant differences on most of perceptual conducts between control and experimental group, whereby adolescents with motor limitations were more aggressive than control group subjects, especially in behaviors that apply to all forms of verbal aggressiveness. All examined adolescents in which some apparent forms of aggressive behavior were noticed in the observation protocol showed comparable expression of aggressiveness according to the results obtained on the subscales of the A-87 aggressiveness questionnaire, which connects these two measuring instruments and justifies their use in the study of aggressiveness regardless of the understanding of the origin of aggression.

Can Questionnaire Reports Correctly Classify Relationship Distress and Partner Physical Abuse?

2006-01-01

Relationship adjustment (e.g., Dyadic Adjustment Scale; DAS) and physical aggression (e.g., Conflict Tactics Scale) measures are used both as screening tools and as the sole criterion for classification. This study created face valid diagnostic interviews for relationship distress and physical abuse, through which one could compare preliminarily the classification properties of questionnaire reports. The DAS (and a global measure of relationship satisfaction) had modest agreement with a structured diagnostic interview; both questionnaires tended to overdiagnose distress compared with the interview. Results for partner abuse reiterated the need to go beyond occurrence of aggression as the sole diagnostic criterion, because men’s aggression was more likely than women’s to rise to the level of “abuse” when diagnostic criteria (injury or substantial fear) were applied.

2015-06-01

The present study was designed to examine the relationship between parents' emotional intelligence and adolescents' aggression, through the mediation of parenting styles. Two hundred and twenty five undergraduate students (113 boys & 112 girls; age 17-18 years), from four universities in Pakistan, participated with their parents. The Parenting Styles and Dimensions Questionnaire (Robinson, Mandleco, Olsen, & Hart, 1995), and the Scale of Emotional Intelligence (Batool & Khalid, 2011) were completed by parents. The Aggression Questionnaire (Buss & Perry, 1992) was completed by their adolescent offspring. Mediational path analysis supported our hypothesised model. Results indicate that emotional intelligence of parents indirectly links to aggression among offspring, through parenting styles. It was concluded that emotional intelligence training will help parents to improve their parenting styles, and it will lower the risk of aggression in their children. © 2014 International Union of Psychological Science.

The aim of this study was to examine the degree of aggressive behaviour of secondary school youth. A survey was conducted among 508 secondary school students in Biała Podlaska district. Among the examined subjects were 231 (45.5%) women and 277 (54.5%) men. The surveyed group was divided into two groups: aged 18 and 19-21 yrs. The research tool was a Buss and Perry Aggression questionnaire (Amity version) and the author's own questionnaire, which was developed for research purposes. It was found that the average level of aggression in all analysed categories (verbal aggression, physical, anger, hostility and aggression in general), was higher in the older group of interviewees (aged between 19 and 21). It was noticed that men are more aggressive than women. Higher level of aggression was noticed among respondents who live in block of flats in the city rather than the residents of singlefamily homes in the countryside. Significant differences were found in the level of overall aggression, physical and verbal aggression depending on the type of school the tested subjects attended to. It was noticed that higher level of aggression affects vocational school students. Having both parents did not influence the occurrence of aggressive behaviour. 1. Significant difference in the level of aggression among males and females requires accurate planning of preventive programmes aimed at specific groups of recipients, including sex. 2. Programmes which prevent negative outcomes of verbal and physical aggression should also influence the age of adolescents.

Nurses can be exposed to aggressive behavior from patients, patient's relatives, colleagues and visitors. To determine the prevalence of workplace aggression among Palestinian nurses in the Hebron district and to examine cross-sectional associations between exposure to workplace aggression and the occurrence of psychological distress and job satisfaction. Of 372 nurses eligible for the study, 343 were included (response rate of 92.2%). The sample comprised 62% females and 38% males. The participants responded to questions about their socio-demographic status, workplace aggression (WHO questionnaires), psychological distress (General Health Questionnaire, GHQ-30), and job satisfaction (Generic Job Satisfaction Scale). Ninety-three (27.1%) of the respondents reported exposure to workplace aggression of any kind. Seventeen (5%) reported exposure to physical aggression, 83 (24.2%) reported exposure to verbal aggression, and 25 (7.3%) reported exposure to bullying. The patients and the patients' relatives were the main sources of physical and verbal aggression, whereas colleagues were the main source of bullying. Males reported a higher prevalence of bullying than females. Younger nurses reported a higher prevalence of exposure to physical aggression, verbal aggression and bullying. Verbal aggression was associated with more psychological distress. Bullying was associated with lower job satisfaction. More than a quarter of the nurses reported that they had been subject to some sort of aggression at the workplace. Verbal aggression was associated with higher psychological distress. Workplace bullying was associated with lower job satisfaction. Increased awareness and preventive measures to address this problem among health care workers are warranted.

Solomon, C R; Serres, F

1999-04-01

The aim of the study was to distinguish the effects of verbal aggression from those of physical aggression and investigate whether parental verbal violence has negative effects on children's self-esteem and academic achievements. One hundred and forty-four 10-year-old children completed the Harter Self-perception Profile for Children questionnaire and a questionnaire concerning their mothers' and fathers' verbal aggression towards them and their use of physical punishment. The researchers used school records to obtain the subjects' marks in French (their native language) and Mathematics. Six children had never been the targets of either verbal aggression or physical punishment. Thirty-four children had been subjected to both types of aggression. Verbal aggression alone was found to be in significant negative correlation with three of six components of self-esteem. Verbal aggression alone was also found to be in significant negative correlation with French marks. In addition children who had been subject to greater verbal aggression had lower self-esteem and lower marks in French than children who had been subject to lesser verbal aggression. They were also significantly negatively affected in a fourth component of self-esteem. Parental verbal aggression alone as separate and distinct from physical punishment contributes to lowering children's self-esteem and school achievements. Given the extent of the use of verbal aggression by ordinary parents the authors suggested a need for parent education on the topic of positive methods of child rearing.

The relationship between the type of physical aggressive behavior, callous/unemotional traits and behavioral problems was extensively studied in the literature, but no similar data exist in Hungarian adolescents. In the present study, the type of aggressive behavior was assessed in adolescents on a normative sample to study its relationship with callous/unemotional traits and behavioral problems. 223 students were participated in the study after informed consent (girls, n=106, age: 14.2±1.5 years; boys, n=117, age: 13.9±1.6 years) from primary and secondary schools in Miskolc and adjacent areas. The Reactive/Proactive Aggression Questionnaire was used to assess the level of aggressive behavior, the Inventory of Callous Unemotional Traits was used to measure callous/unemotional traits, while behavioral problems were established by the means of the Strengths and Difficulties Questionnaire. In the present non-clinical sample, the level of reactive aggression was higher than the level of proactive aggressive behavior. In boys, proactive and total aggression measures were significantly higher compared to girls. In both genders, reactive aggression was specifically associated with emotional and peer-related problems. Proactive aggression was correlated positively with callous traits in both genders, while self-reported prosocial behavior had an inverse correlation with proactive aggressive behavior in boys. Self reported conduct- and hyperactivity problems were positively correlated with both types of aggressive behavior in both genders. The strongest positive correlation was observed between self-reported conduct symptoms and both types of aggressive behavior. Callous/unemotional traits were related with proactive forms of aggression, similar to literature data. Reactive aggressive behavior was related to peer-related and emotional problems, thus our data outlined the importance of the distinction between the two main types of aggression.

International studies show that aggressive behavior against primary care physicians is not an uncommon occurrence. There has been no systematic study to date of the nature and frequency of such occurrences in Germany. A four-page questionnaire was sent to a nationwide random sample of 1500 primary care physicians. It contained questions about the type, frequency, severity, and site of aggressive behavior against the physician. 831 (59%) of 1408 correctly delivered questionnaires could be included in the analysis. 91% of the respondents (95% confidence interval [CI], 89%-93%) said they had been the object of aggressive behavior at some time in their career as a primary care physician, 73% (95% CI, 70%-76%) in the previous 12 months. Severe aggression or violence had been experienced by 23% (95% CI, 20%-25%) in their entire career and 11% (95% CI, 8%-13%) in the previous year. The vast majority of respondents said they felt safe in their offices. 66% of female and 34% of male respondents said they did not feel safe making house visits while on on-call duty. The frequency and extent of aggression and violence against primary care physicians in Germany is comparable to those reported by international studies. Strategies for dealing with this problem should be developed. In particular, the issue of safety on emergency call needs to be addressed.

Victimization and aggression among adolescents in school settings is a growing problem, not yet fully understood or properly evaluated, particularly in Portugal. A sample of 1320 adolescents was recruited (52.7% female), with ages varying from 10 to 18 years old, attending middle and high school. Confirmatory factor analysis confirms the measurement model of the instrument's bully and victim versions, as evaluating overt, relational, and reputational aggression/victimization and providing/receiving prosocial behavior, respectively. This measurement model was invariant across schooling and gender, showed adequate internal consistency indicators, and presented evidence for construct validity in relation to other variables. Descriptive analyses indicate that boys are more aggressive in overt and relational forms and victimized through overt aggression, whereas girls are more aggressive and victimized relationally. More than any form of aggression or victimization, boys and girls revealed higher values for engaging in and receiving prosocial behavior. These results suggest that this instrument is a reliable, valid, and structurally sound measure of aggression, victimization and prosocial behavior in this Portuguese school-based community sample. Hence, its use may assist researchers in gaining a better understanding of adolescent aggression and victimization. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Excessive aggression is a common behaviour problem in dogs that can have various destructive effects on the affected people and the implicated dog. Aggressive behaviour directed towards the owner or other family members is one of the most frequently occurring aggressive phenotypes. Here, we examine the reliability of a short questionnaire assessing aggressive behaviours by two, contextually different behavioural tests: ‘take away bone’ and ‘roll over’. Based on dogs' behaviour in the tests, we sorted dogs (N = 93) in two groups for each test, namely a less and a more disobedient/resistant group. The two principal components obtained in our questionnaire—‘obedient’ and ‘aggressive towards owner’—showed significant differences between the behaviour groups. While dogs in the less disobedient/resistant groups had significantly higher ‘obedient’ and significantly lower ‘aggressive towards owner’ scores, dogs in the more disobedient/resistant groups had significantly higher ‘aggressive towards owner’ and significantly lower ‘obedient’ scores. Dogs' age, sex and neuter/spay status expressed their effect through interactions. Males, young dogs and intact dogs were less ‘obedient’ than older ones, while resistant spayed/neutered dogs were more aggressive towards the owner. The questionnaire used is a safe, easy to deploy and time-efficient tool to reliably assess certain owner-directed aggressive tendencies of family dogs. PMID:29134099

We previously reported that trait aggression, proposed as an endophenotype for suicidal behavior, is positively associated with Toxoplasma gondii ( T. gondii ) seropositivity in females, but not in males. Additionally, older males seropositive for T. gondii had lower scores on measures of trait aggression, including self-aggression. Trait aggression may be influenced by dopaminergic signaling, which is known to be moderated by gender and age, and potentially enhanced in T. gondii positives through the intrinsic production of dopamine by the microorganism. Therefore, we investigated associations between trait aggression and interactions between T. gondii enzyme-linked immunoabsorbant assay (ELISA) IgG titer-determined seropositivity and high-performance liquid chromatography- (HPLC-) measured blood levels of dopamine precursors phenylalanine (Phe), tyrosine (Tyr), and their ratio in a sample of 1000 psychiatrically healthy participants. Aggressive traits were assessed using the questionnaire for measuring factors of aggression (FAF), the German version of the Buss-Durkee hostility questionnaire. We found that 1) the decrease in trait aggression scores in T. gondii -positive older males was only present in individuals with a low Phe:Tyr ratio, and 2) that there was a positive correlation between Phe:Tyr ratio and total aggression and selected subscales of aggression in T. gondii -positive males, but not in T. gondii -negative males. These findings point toward a gender-specific reciprocal moderation by Phe:Tyr ratio and T. gondii seropositivity of their associations with aggression scores, and lead to experimental interventions geared to manipulating levels of dopamine precursors in selected T. gondii positive individuals with increased propensity for aggression.

The incidence of juvenile delinquency has increased in the past decade in India and juvenile crimes are increasingly being reported. This has been attributed to many biopsychosocial factors. It is essential to understand these issues in the context of India to determine the response of acts of children in conflict with the law. We aimed to assess the sociodemographic characteristics and the aggression quotient of children in conflict with the law (juvenile delinquents) in observation homes across India and compare them with those who were not. We did a case-control study in five juvenile homes in the cities of Hyderabad, Lucknow and Pune. Ninety inmates (74 boys, 16 girls) were included in the study. Sociodemographic characteristics and aggression quotient of children in conflict with the law were evaluated using two separate questionnaires, i.e. a sociodemographic questionnaire and the modified Buss and Perry aggression questionnaire. These were compared with a control group of similar age, sex and income status. All the children in conflict with the law surveyed belonged to the lower socioeconomic strata, had a significantly higher chance (p<0.05) of coming from broken homes, have addictions, jailed family members and suffered physical and sexual abuse than controls. They also scored higher on all domains of the aggression questionnaire than controls. A collection of sociodemographic attributes such as broken homes, addictions and abuse seem to have an important association with juvenile delinquency. Children in conflict with the law are also more likely to be associated with a higher aggression quotient as compared to children who were not. Copyright 2015, NMJI.

Parental attitudes and aggression in the Emo subculture.

Chęć, Magdalena; Potemkowski, Andrzej; Wąsik, Marta; Samochowiec, Agnieszka

2016-01-01

A better functioning of adolescents involves proper relationships with parents, whereas negative relationships lead to aggressive behaviour. Young members of Emo subculture, characterised by deep emotional sensitivity, are particularly vulnerable to parental influence. The aim was to specify a relationship between parental attitudes and aggression among adolescents from the Emo subculture in comparison with a control group. 3,800 lower secondary school students took part in the introductory research. A target group constituted 41 people from the Emo subculture as well as a control group involving 48 people. A screening survey, the Parental Attitudes Scale, the Aggression Questionnaire and the author's questionnaire including questions concerning the functioning in the Emo subculture were used in the study. The results obtained in the research study suggest that there is a relationship between the indicated improper parental attitudes and aggressive behaviour among adolescents from the Emo subculture in comparison with the control group. In the Emo subculture, teenagers'aggressive behaviour is related to improper parental attitudes. It has been stated that mother's attitudes, irrespective of subculture, are much more strongly associated with the aggression among adolescents than father's attitudes. Moreover, aggressive behaviour in the Emo subculture occurs when father displays an excessively demanding attitude. A reduction of the level of almost all kinds of aggression manifested among teenagers from the Emo subculture is associated with mothers' attitude of acceptance. Mothers' autonomous attitude leads to an increase in the aggression in this group, whereas an inconsistent attitude of mothers fosters an increase in aggression among all teenagers.

2017-09-01

Several studies have related aggressive and risky driving behaviours to accidents. However, the cognitive processes associated with driving aggression have received very little attention in the scientific literature. With the aim of shedding light on this topic, the present research was carried out on a sample of 414 participants in order to validate the Driver's Angry Thoughts Questionnaire (DATQ) with a sample of Spanish drivers and to test the hypothesis of the mediation effect of aggressive and risky driving on the relationship between drivers' angry thoughts and crash-related events. The results showed a good fit with the five-factor model of the questionnaire (Judgmental and Disbelieving Thinking, Pejorative Labelling and Verbally Aggressive Thinking, Revenge and Retaliatory Thinking, Physically Aggressive Thinking, and Coping Self-Instruction). Moreover, slight gender differences were observed in drivers' angry thoughts, with women scoring higher than men (η 2 =0.03). However, younger drivers had higher scores than older drivers in general (η 2 =0.06). Finally, several mediation effects of aggressive driving and risky driving on the relationship between aggressive thinking and the crash-related events were found. Implications of the results for research in traffic psychology and clinical assessment of aggressive drivers as well as limitations of the study are discussed. Copyright © 2017 Elsevier Ltd.

The Appetitive Aggression Scale—development of an instrument for the assessment of human's attraction to violence.

PubMed Central

Weierstall, Roland; Elbert, Thomas

2011-01-01

Background Several instruments, notably Buss and Perry's Aggression Questionnaire, have been developed for the assessment of aggressive behavior. However, in these instruments, the focus has been on reactive rather than instrumental forms of aggression, even though men in particular may find aggressive behavior attractive. A questionnaire or structured interview for the systematic assessment of the attraction to violence is not yet available. Objective We, therefore, developed a freely available short form for the assessment of a person's attraction to violent and planned forms of aggression based on reports of former combatants on the attraction to violence and the characteristics of instrumental aggression described in the literature. Method The Appetitive Aggression Scale (AAS) was administered to nine samples drawn from different populations, with a total of 1,632 former combatants and participants from war-affected regions (1,193 male and 439 female respondents). Results From the initial set of 31 items, a selection of 15 items was extracted to improve the scale's psychometric properties and assess the construct of appetitive aggression validly with respect to content. Cronbach's Alpha coefficient of 0.85 was appropriate. All items loaded significantly on a single factor accounting for 32% of the total variance. Further analysis revealed that the scale measures a specific construct that can be distinguished from other concepts of human aggression. Conclusions With the AAS, we present an easily administrable tool for the assessment of the attraction to violence. PMID:22893817

Park, MiJeong; Choi, Jihea; Lim, Seung-Joo

2014-12-01

The study was undertaken to assess levels of aggression, and to determine factors affecting aggression among South Korean middle school students. A descriptive study was conducted using self-report questionnaires. The participants were 340 girls and boys from two middle schools and 302 questionnaires were used for the final data analysis. Aggression, academic stress, depression, self esteem, decision-making competency, and happiness were measured. Data were analyzed using descriptive statistics including t tests, one-way analysis of variance, Pearson's correlation coefficients and multiple regressions. Aggression had significant correlations with academic stress (r = .21, p < .001), depression (r = .43, p < .001), self esteem (r = -.25, p < .001), decision-making competency (r = -.25, p < .001), and happiness (r = -.21, p < .001). Mean score for aggression was 2.49 out of 5. Significant explanatory variables for aggression were grade (t = 4.39, p < .001), academic stress (t = 2.78, p = .006), and depression (t = 5.03, p < .001). The explanatory power of these factors was 26.9%, and this was statistically significant (F = 16.06, p < .001). Findings indicate that depression, academic stress, and grade (second grade) influence aggression. To decrease aggressive behavior, it is necessary to provide systematic and political programs in schools and local communities that can ameliorate negative emotional factors like depression and academic stress. Additionally, development of positive factors such as self esteem, decision-making skills, and happiness in middle school students is important to reduce aggression. Copyright © 2014.

2014-01-01

Objective Aggression in schizophrenia is a major societal issue, leading to physical harm, stigmatization, patient distress, and higher healthcare costs. Impulsivity is associated with aggression in schizophrenia, but it is multidetermined. The subconstruct of urgency is likely to play an important role in this aggression, with positive urgency referring to rash action in context of positive emotion, and negative urgency to rash action in context of negative emotion. Method We examined urgency and its neural correlates in 33 patients with schizophrenia or schizoaffective disorder and 31 healthy controls. Urgency was measured using the Urgency, Premeditation, Perseverance and Sensation Seeking scale. Aggressive attitudes were measured using the Buss Perry Aggression Questionnaire. Results Positive urgency, negative urgency, and aggressive attitudes were significantly and selectively elevated in patients (1.21< Cohen’s ds < 1.50). Positive and negative urgency significantly correlated with Aggression Questionnaire total score (rs>.48) and each uniquely accounted for a significant portion of the variance in aggression over and above the effect of group. Urgency measures correlated with reduced cortical thickness in ventral prefrontal regions including right frontal pole, medial and lateral orbitofrontal gyrus and inferior frontal gyri, and rostral anterior cingulate cortex. In patients, reduced resting state functional connectivity in some of these regions was associated with higher urgency. Conclusions Findings highlight the key role of urgency in aggressive attitudes in people with schizophrenia and suggest neural substrates of these behaviors. They also suggest behavioral and neural targets for interventions to remediate urgency and aggression. PMID:25073506

Effects of viewing relational aggression on television on aggressive behavior in adolescents: A three-year longitudinal study.

PubMed

Coyne, Sarah M

2016-02-01

Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing relational aggression on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of different questionnaires involving media and aggression at 3 different time points. Results revealed that viewing relational aggression on TV was longitudinally associated with future relational aggression. However, early levels of relational aggression did not predict future exposure to televised relational aggression. Conversely, there was a bidirectional relationship between TV violence and physical aggression over time. No longitudinal evidence was found for a general effect of viewing TV, as all significant media effects were specific to the type of aggression viewed. These results support the general aggression model and suggest that viewing relational aggression in the media can have a long-term effect on aggressive behavior during adolescence.

2006-06-01

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.

Strang, Emily; Peterson, Zoë D

2013-12-01

Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

This study examined three models depicting the relations between mother and father attachment, self-esteem and aggression. A total of 385 participants (173 males and 212 females), aged from 18 to 20 years, completed self-rating questionnaires covering mother and father attachment, self-esteem and aggression. Results showed that self-esteem had additive and mediation effects on both the father attachment-aggression and mother attachment-aggression relationships, and also moderated the mother attachment-aggression relation. These findings are discussed in terms of different models for the inter-relations of mother and father attachment, self-esteem and aggression in late adolescence. Copyright 2006 Wiley-Liss, Inc.

2009-01-01

The aim of the study was to evaluate the consequences of the exposure to workplace aggression from coworkers and clients. Participants belonged to two professional groups: nurses (N = 1163) and public service workers (N = 391). Aggression from coworkers and clients/patients was analysed separately. Several multiple regression models were tested to assess the effect of work-related aggression experienced by the subjects on their job satisfaction, professional functioning and mental health status. The frequency and type of violent behaviours against employee was measured by Exposure to Workplace Aggression Questionnaire (EWAQ), level of burnout was determined by Maslach Burnout Inventory (MBI), mental health status by General Health Questionnaire (GHQ-28), and the level of work satisfaction was measured by 22-items survey, developed at NIOM Work Psychology Department. In the regression models, several possible confounders were controlled (sex, age, individual direct reaction to aggressive act, and physical health status). Results of our study point to adverse consequences of exposure to aggression at workplace, irrespective of its source. Employees experiencing workplace aggression are less satisfied with work, show symptoms of burnout, and their general health is poorer. We assume that aggression towards coworkers by peers and supervisors, as the phenomenon reflecting quality of long term interpersonal relationships, may affect health and functioning of workers stronger than a single incident in the short term contacts with clients. Aggression from clients usually results in compassion of peers, and it is perceived as the organisational problem that should be solved. On the contrary, dealing with an aggressive coworker usually is perceived as employee's own business and results in the sense of unfairness and isolation.

The aim of this study was to identify implicit cognitive predictors of aggressive behavior. Specifically, the predictive value of an attentional bias for aggressive stimuli and automatic association of the self and aggression was examined for reactive and proactive aggressive behavior in a non-clinical sample (N = 90). An Emotional Stroop Task was used to measure an attentional bias. With an idiographic Single-Target Implicit Association Test, automatic associations were assessed between words referring to the self (e.g., the participants' name) and words referring to aggression (e.g., fighting). The Taylor Aggression Paradigm (TAP) was used to measure reactive and proactive aggressive behavior. Furthermore, self-reported aggressiveness was assessed with the Reactive Proactive Aggression Questionnaire (RPQ). Results showed that heightened attentional interference for aggressive words significantly predicted more reactive aggression, while lower attentional bias towards aggressive words predicted higher levels of proactive aggression. A stronger self-aggression association resulted in more proactive aggression, but not reactive aggression. Self-reports on aggression did not additionally predict behavioral aggression. This implies that the cognitive tests employed in our study have the potential to discriminate between reactive and proactive aggression. Aggr.

The phenomenon of violence and aggression in the workplace is frequent and constantly increasing. Healthcare professionals are most exposed to this phenomenon, especially those who work in urgent and psychiatric emergency departments. To validate the Italian version of the questionnaire "Workplace Violence in the Health Sector Case Study Research Instruments Survey Questionnaire", conducted by WHO. 55 randomly selected workers took part in the validation of the questionnaire among physicians, nurses and nursing trainees. The internal consistency analysis of the demand of 5 dichotomous variables on binary values ​​for violence levels suggests that Cronbach's alpha is 0.61, and Cronbach's alpha calculated on standardized elements is 0.69, which means that Reliability shows sufficient levels. The Italian translation carried out in this WHO questionnaire study shows good internal reliability and consistency and could be considered a useful tool in assessing and preventing aggression and violence against health professionals.

Context Childhood trauma may predispose individuals to aggressive behavior, and both childhood trauma and aggressive behavior are associated with hypothalamicpituitary-adrenal axis dysregulation. Objective To determine whether there would be an interaction between genetic variation in FKBP5 and childhood trauma in predicting aggressive behavior. Design Cross-sectional study. Four FKBP5 single-nucleotide polymorphisms used in previous studies (rs3800373, rs9296158, rs1360780, and rs9470080) were genotyped. Three diplotypes were derived from 2 major putatively functional haplotypes regulating protein expression that were previously associated with glucocorticoid receptor sensitivity. Setting Penitentiary District of Abruzzo-Molise in central Italy. Participants A population of 583 male Italian prisoners recruited between 2005 and 2008. Main Outcome Measures A comprehensive analysis of aggression and impulsivity was undertaken using the Brown-Goodwin Lifetime History of Aggression (BGHA) questionnaire, the Buss-Durkee Hostility Inventory (BDHI), and the Barratt Impulsiveness Scale (BIS). A history of childhood trauma was investigated with the Childhood Trauma Questionnaire. The interaction between the FKBP5 diplotypes and childhood trauma on measures of aggression was analyzed. Analyses were replicated with a second behavioral measure of aggression: violent behavior in jail. Individual single-nucleotide polymorphism analysis was performed. Results Childhood trauma had a significant effect on BGHA and BDHI scores but not on BIS scores. We observed a significant influence of the FKBP5 high-expression diplotype on both a lifetime history of aggressive behavior (BGHA) (P = .012) and violent behavior in jail (P = .025) but only in individuals exposed to childhood trauma, in particular to physical abuse. No main effect of the FKBP5 diplotypes was observed. Conclusion These data suggest that childhood trauma and variants in the FKBP5 gene may interact to increase the risk of overt aggressive behavior.

This study extends the use of the Impulsive/Premeditated Aggression Scale for subtyping aggressive behavior among adolescents with Conduct Disorder. Of the Conduct Disorder symptoms, aggression has the strongest prognostic and treatment implications. While aggression is a complex construct, convergent evidence supports a dichotomy of impulsive and premeditated aggressive subtypes that are qualitatively different from one another in terms of phenomenology and neurobiology. Previous attempts at measuring subtypes of aggression in children and adults are not clearly generalizable to adolescents. Sixty-six adolescents completed a questionnaire for characterizing aggression (Impulsive/Premeditated Aggression Scale), along with standard measures of personality and general functioning. Principal components analysis demonstrated two stable factors of aggression with good internal consistency and construct validity. Compared to the premeditated aggression factor, the impulsive aggression factor was associated with a broader range of personality, thought, emotional, and social problems. As in the adult and child literature, characterization of aggressive behavior into two subtypes appears to be relevant to understanding individual differences among adolescents with Conduct Disorder.

Aggressive patterns of behavior often start early in childhood, and tend to remain stable into adulthood. The negative consequences include poor academic performance, disciplinary problems and encounters with the juvenile justice system. Early school intervention programs can alter this trajectory for aggressive children. However, there are no studies evaluating the feasibility of such interventions in Africa. This study therefore, assessed the effect of group-based problem-solving interventions on aggressive behaviors among primary school pupils in Ibadan, Nigeria. This was an intervention study with treatment and wait-list control groups. Two public primary schools in Ibadan Nigeria were randomly allocated to an intervention group and a waiting list control group. Teachers rated male Primary five pupils in the two schools on aggressive behaviors and the top 20 highest scorers in each school were selected. Pupils in the intervention school received 6 twice-weekly sessions of group-based intervention, which included problem-solving skills, calming techniques and attribution retraining. Outcome measures were; teacher rated aggressive behaviour (TRAB), self-rated aggression scale (SRAS), strengths and difficulties questionnaire (SDQ), attitude towards aggression questionnaire (ATAQ), and social cognition and attribution scale (SCAS). The participants were aged 12 years (SD = 1.2, range 9-14 years). Both groups had similar socio-demographic backgrounds and baseline measures of aggressive behaviors. Controlling for baseline scores, the intervention group had significantly lower scores on TRAB and SRAS 1-week post intervention with large Cohen's effect sizes of 1.2 and 0.9 respectively. The other outcome measures were not significantly different between the groups post-intervention. Group-based problem solving intervention for aggressive behaviors among primary school students showed significant reductions in both teachers' and students' rated aggressive behaviours with large effect sizes. However, this was a small exploratory trial whose findings may not be generalizable, but it demonstrates that psychological interventions for children with high levels of aggressive behaviour are feasible and potentially effective in Nigeria.

This study used a within-participant design to evaluate the concurrent validity and test-retest reliability of the Violent Ideations Scale in a general population, English-speaking opportunistic sample. Data from 116 adult participants ( M age = 33.7, SD = 11.9, male = 30 [25.9%]) were used to compare scores on the Violent Ideations Scale and Aggression Questionnaire and responses to the Schedule of Imagined Violence. A subgroup of 27 participants ( M age = 37.2, SD = 13.6, male = 8 [29.6%]) completed the Violent Ideations Scale on a second occasion, 2 weeks later. The Violent Ideations Scale was found to correlate significantly with the Aggression Questionnaire subscale and total scores, with the strongest correlations being with physical aggression and total scores. Participants were more likely to be categorized as having experienced a violent ideation based on responses to the Violent Ideation Scale, compared with the Schedule of Imagined Violence, most likely due to the Schedule of Imagined Violence underestimating the prevalence of violent ideation. A significant, strong correlation was found between total Violent Ideations Scale scores at Time 1 and Time 2. Overall, the Violent Ideations Scale was found to have concurrent validity when compared with the Aggression Questionnaire and good test-retest reliability, suggesting that it would be suitable for use with a nonclinical, English-speaking sample.

Mental stress is inseparably connected with work. The stress reaction is favored by stagnation in life, lack of prospects for professional growth, uncertainty of stable employment, pressure to work reliably and flexibly, excessive workload, and lack of assigned duties. Interpersonal relations among members of the team represent another significant factor in the appearance and persistence of social pathology. Identification of forms and sources of aggression implicated in stress among physicians at the workplace. The study was performed in 501 physicians employed by inpatient and outpatient institutions in the province of Podlaskie. We used questionnaires assessing the intensity and type of aggression against physicians and the GHQ28 General Heath Questionnaire. The patient source of stress for physicians included hostile comportment (53%) and extortion (41%). The source of stress from superiors included vulgar acts in the presence of coworkers (18%) and threats (17%). Stress was also caused by raised voice of other physicians (44%) and nurses (25%). The main source of stress for physicians was aggression by patients and fellow physicians.

The study was conducted by using two questionnaires: the Psychological Inventory of Aggression Syndrome-1 authorship by Z.B. Gaś as well as Extinguishes and the Chosen Marriage Questionnaire-2 developed by M. Plop and J. Rostowski The analysis of the results showed the influence of the weight loss on the aggressive behaviour at the examined group. Important differences were shown in the first phase of the examination among the examined group and the control group on scales: emotional self-aggression, the hostility towards surroundings and directed outside aggression. Regression analysis showed a statistical relationship between outward aggression and disappointment, 0.346 p<0.01, intimacy 0.943 p<0.01, and the result of general satisfaction with the relationship 0.832 p<0.05.While self-realization is negatively correlated with a displaced aggression -0.342 p<0.01 and the intermediate one -0.225 p<0.01. Hostility towards the environment correlates positively with intimacy 0.326 p<0.01. Indirect aggression correlates negatively with a disappointment -0.324 for p <0.05. Important differences were shown in the second stage of the examination among groups examined on the scale inspection of the aggressive behaviour. Substantial results weren't demonstrated on scales: emotional self-aggression, hostility towards the environment and directed outside aggression In the regression analysis we received a statistically significant result: controlling an aggressive behavior correlates negatively with disappointment -0, 355 p <0,01. However, no statistically significant results were received from the partners of obese people. Weight loss after gastric-by-pass surgery has the significant impact on the rarer occurrence of an aggressive behavior, which improving the quality of the connubial or cohabitation relationship.

Violence among adolescents is one of the most serious problems, and has significantly increased in recent years. Studies conducted in 2011 on aggression and violence in schools reported that the most widespread form of offence is verbal aggression. As many as 63% of students had experience of being ridiculed, humiliated or offended. According to research, 33% of students suffered from physical aggression (PA). The aim of the study to evaluate the relationship between physical activity and the incidence of aggressive behaviour in adolescents of lower -secondary school age. The study was conducted in autumn 2013, in West Pomerania province in Poland, among 807 students of a lower -secondary school. A diagnostic survey method with a standardized questionnaire (Aggression Questionnaire) by H. Buss and M. Perry of 1992 (Amity version) was used. Statistical analysis was performed in Statistica Pl version 10 using the Kruskal–Wallis test and the U Mann–Whitney test with a significance level of p ≤ 0.05. The Kruskal–Wallis test showed only a statistically significant difference between the groups surveyed in relation to the frequency of attendance at additional sports activities and the level of PA (p = 0.02). Subjects who engage in team sports show a higher tendency for physical aggression than those engaged in individual sports. Taking into account the higher level of PA in adolescents performing sport 3–4 times a week compared to physically inactive and very active adolescents (more than 5 times a week), it may be presumed that sport attracts people with high physical aggression tendencies. Only with strong involvement in sport is the level of aggression reduced. There is a need for research on the personality of young athletes, which would give credence to this thesis.

Recent advances in the study of affective-cognitive regulation of aggressive behavior suggest positive correlations between poor executive capacities (ECF) and dispositional negative reactivity (Posner & Rothbart, 2000). If the global assumption is correct what are the likely implications of predicted relation? The central issue in present research was to verify this assumption and examine how situational characteristics could alter executive performance in persons with Dysexecutive Syndrome (DES, Baddeley, 1998) and healthy adults (students, health workers) to explore some of the consequences of those modifications for aggressive tendencies. Precisely, we expected the positive correlations between poor executive performances and high aggressive tendencies at dispositional as well situational levels, except for health workers, given their professional duties. In order to assess cognitive capacities and dispositional as well as situational aggressive tendencies, during two studies (First study: N=60 students; Second study: N= 60 students, N= 24 patient with Dysexecutive Syndrome, N= 45 health care workers) right-handed French-speakers participants completed twice, during an initial phase of the study and one week after, a series of standard executive functions neuropsychological tests and aggression questionnaires. During second phase, participants executed a task introducing the experimental feedbacks (success, neutral, failure) before completion of neuropsychological tests and questionnaires. The results provided evidence of a dispositional relationship between poor executive functioning and aggressive tendencies, and extended it to situational level. For all participants, it showed that increases in impulsiveness (negative emotionality and aggressive choices) due to a negative feedback were concomitant with an inability to focus individuals’ attention on ongoing tasks.

This study used the latent class analysis (LCA) to identify and classify Chinese adolescent children's aggressive behaviors. It was found that (1) Adolescent children could be divided into four categories: general children, aggressive children, victimized children and aggressive victimized children. (2) There were significant gender differences among the aggressive victimized children, the aggressive children and the general children. Specifically, aggressive victimized children and aggressive children had greater probabilities of being boys; victimized children had equal probabilities of being boys or girls. (3) Significant differences in loneliness, depression, anxiety and academic achievement existed among the aggressive victims, the aggressor, the victims and the general children, in which the aggressive victims scored the worst in all questionnaires. (4) As protective factors, peer and teacher supports had important influences on children's aggressive and victimized behaviors. Relative to general children, aggressive victims, aggressive children and victimized children had lower probabilities of receiving peer supports. On the other hand, compared to general children, aggressive victims had lower probabilities of receiving teacher supports; while significant differences in the probability of receiving teacher supports did not exist between aggressive children and victimized children.

The link between empathy and aggression is well documented; yet, studies examining potential mechanisms that explain this association are limited. In the present study, we tested the relation between empathy and aggression and examined both the mediating and moderating effects of moral disengagement on this relation among Chinese male juvenile delinquents. Three hundred and fifty-seven male juvenile delinquents from one Chinese juvenile correctional facility completed the interpersonal reactivity index, the moral disengagement scale and the aggression questionnaire. The results indicated that moral disengagement partially mediated the influence of empathy on aggression. Moreover, moral disengagement moderated the relation between empathy and aggression. Specifically, there was a significant negative relation between empathy and aggression at low levels of moral disengagement. However, at high levels of moral disengagement, the relation between empathy and aggression was non-significant. The significance and limitations of the results are discussed.

Individual, team, and coach predictors of players' likelihood to aggress in youth soccer.

The purpose of this study was to examine personal and socioenvironmental factors of players' likelihood to aggress. Participants were youth soccer players (N = 258) and their coaches (N = 23) from high school and club teams. Players completed the Judgments About Moral Behavior in Youth Sports Questionnaire (JAMBYSQ; Stephens, Bredemeier, & Shields, 1997), which assessed athletes' stage of moral development, team norm for aggression, and self-described likelihood to aggress against an opponent. Coaches were administered the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999). Using multilevel modeling, results demonstrated that the team norm for aggression at the athlete and team level were significant predictors of athletes' self likelihood to aggress scores. Further, coaches' game strategy efficacy emerged as a positive predictor of their players' self-described likelihood to aggress. The findings contribute to previous research examining the socioenvironmental predictors of athletic aggression in youth sport by demonstrating the importance of coaching efficacy beliefs.

This study investigated aggressive behaviour in Serbian adolescents with intellectual disability (ID) compared to typically developing peers. The sample consisted of both male and female adolescents aged 12-18 years. One hundred of the adolescents had ID, and 348 adolescents did not have ID. The adolescents were asked to complete the Reactive-Proactive Aggression Questionnaire (RPQ), and their teachers provided ratings of aggression for the adolescents using the Children's Scale of Hostility and Aggression: Reactive-Proactive (C-SHARP). Results indicated that adolescents reported a higher prevalence of aggressive behaviour than their teachers. Reactive aggression was more prevalent than proactive aggression in both subsamples. In the subsample of adolescents with ID, there were no sex or age differences for aggression. However, in the normative subsample, boys and older adolescents scored significantly higher on aggression. According to adolescent self-reports the prevalence of aggression was higher in adolescents without ID, while teachers perceived aggressive behaviour to be more prevalent in adolescents with ID. Scientific and practical implications are discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

This study examined the effectiveness of Chinese martial arts in reducing reactive and proactive aggressive behavior among schoolchildren with a cluster-randomized trial. A screening questionnaire was completed by 3511 schoolchildren of Grades 2 to 5 from 13 sites in Hong Kong. We shortlisted 298 children who scored z ≥ 1 on the total score of the Reactive-Proactive Aggression Questionnaire in their respective sites to participate in the experiment. They were divided into 31 clusters that were blinded and randomly assigned to one of the 4 conditions: skills only, philosophy only, skills and philosophy, and physical fitness (placebo). Subjects were assessed at baseline, posttraining, and 6 months after training using aggression scales. Results from the linear mixed model indicated that the time × training interaction effects were significant for aggressive behavior (reactive and proactive), delinquent behavior, anxiety/depression, and attention problems. Although all measures declined in all conditions over time, only the skills-and-philosophy condition showed a significant reduction at posttraining and/or 6-month follow-up compared with the placebo. The results provided a theoretical proof for the relationship between aggression and sport involvement combined with children's moral reasoning. This study gives practical implications to intervention that solely playing sports or teaching moral lessons is not effective enough for high-risk schoolchildren with aggressive behavior. However, combined traditional Chinese martial arts skills and moral philosophy training could be considered in the school curriculum to reduce school violence and facilitate creation of harmonious schools.

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.

Consistent with the view that adolescent relationships are established in the context of important characteristics of their social networks, we examined the effects of adolescents’ experiences of parenting (psychological control and positive monitoring) and of peer aggression and victimization, on their self reports of dating victimization and aggression. We also examined the effects of individual differences in emotional and behavioral problems. We used questionnaire data from a population-based sample of youth 12–18 years old who were in dating relationships (n = 149). Parental monitoring emerged as a protective factor in reducing both dating victimization and relational aggression. Our findings also point to a significant transfer of aggression in peer relationships to relational aggression in dating relationships. PMID:27307651

Background Controversies remain over the safety and efficacy of vitamin E (i.e., α–tocopherol) supplementation use for the prevention of prostate cancer (CaP); however, associations of different tocopherol forms and CaP aggressiveness have yet to be examined. Methods This study examined whether food intake of tocopherols, vitamin E supplement use, and adipose tissue biomarkers of tocopherol were associated with CaP aggressiveness among African-American (AA, n=1,023) and European-American (EA, n=1,079) men diagnosed with incident CaP. Dietary tocopherols were estimated from a food frequency questionnaire, supplement use from questionnaire/inventory, and biomarkers from abdominal adipose samples measured using high-performance liquid chromatography. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated from logistic regression comparing high aggressive CaP to low/intermediate aggressive CaP, adjusting for covariates. Results Dietary intakes of α-and δ-tocopherol were related inversely to CaP aggressiveness among EAs [OR (95% CI), highest versus lowest quartile: α-tocopherol, 0.34 (0.17–0.69), Ptrend = 0.006; δ-tocopherol, 0.45 (0.21–0.95) Ptrend = 0.007]. Inverse associations between dietary and supplemental α-tocopherol and CaP aggressiveness were observed among AAs, though these did not reach statistical significance [OR (95% CI), highest versus lowest quartile: dietary α-tocopherol, 0.58 (0.28–1.19), Ptrend = 0.20; supplemental α-tocopherol, 0.64 (0.31–1.21) Ptrend = 0.15]. No significant association was observed between adipose tocopherol levels and CaP aggressiveness [OR (95% CI), highest versus lowest quartiles of α-tocopherol for EAs 1.43 (0.66–3.11) and AAs 0.66 (0.27–1.62)]. Conclusions The inverse associations observed between dietary sources of tocopherols and CaP aggressiveness suggests a beneficial role of food sources of these tocopherols in CaP aggressiveness.

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed. We analyzed their thorax and pelvis movements, as well as speed of gait. Participants completed personality questionnaires, including a Big Five measure and a trait aggression questionnaire. We found that gait related to several of our personality measures. The magnitude of upper body movement, lower body movement, and walking speed, were related to Big Five personality traits and aggression. Here, we present evidence that some gait measures can relate to Big Five and aggressive personalities. We know of no other examples of research where gait has been shown to correlate with self-reported measures of personality and suggest that more research should be conducted between largely automatic movement and personality.

This study examines the association between maternal childhood maltreatment and psychopathology and aggression in intimate relationships during pregnancy and the postpartum period. Forty-four pregnant women who were recruited from an obstetric clinic and local advertising periodical completed questionnaires about childhood maltreatment and psychopathology during their first trimester of pregnancy. Approximately 1 year after the birth of the child, 32 of the original participants completed these same questionnaires. Regression models were used to test the relationship between childhood maltreatment and psychopathology and aggression during pregnancy and 1 year postpartum. Sexual abuse and emotional neglect were related to psychopathology during pregnancy, and emotional neglect and physical abuse and neglect predicted poorer maternal outcomes 1 year postpartum. Contrary to expectations, physical abuse was related to less aggression during pregnancy, and emotional abuse was associated with less pathology postpartum. The results of this study indicate that childhood maltreatment is associated with poorer maternal mental health during pregnancy and 1 year postpartum and points to the need to improve targeting and treatment of psychopathology during this time.

There is a strong link between personality disorders (PDs) and aggression. This is reflected in high prevalence rates of PD diagnoses in forensic samples, and in several diagnostic criteria of PDs directly referring to elevated levels of aggression. Aggression can stem from two distinct types of motivation; reactive or impulsive aggression that serves as a defensive reaction to provocation, and proactive or premeditated aggression used to gain extrinsic benefits. Although some clinical conditions like antisocial, borderline, and narcissistic PDs or PD traits, have been empirically linked to reactive and/or proactive aggression, the current study pioneers assessing the relationship between reactive and proactive aggression and traits of all 10 PDs. A mixed sample of patient and non-patient (N=238) participants were administered with the SCID II to assess the level of PD traits; they also completed the Reactive Proactive Questionnaire to determine levels of reactive and proactive aggression. Results showed that paranoid PD traits were positively related to reactive aggression, whereas proactive aggression was uniquely related to antisocial PD traits. This highlights the importance of differentiating between distinct motivations for aggression in PD samples. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Aim of the study: This study tried to identify risk factors of aggressive behavior in a population of schizophrenic inpatients. We tested the association between aggressive behavior and socio-demographic characteristics, addictive disorders, history of suicide attempt, and sexual violence, impulsivity, and sensation seeking. Methods: All consecutive schizophrenic inpatients (100) were assessed during 6 months. Aggressive behavior was quantified with a standardized scale, the Overt Aggression Scale (OAS). We studied socio-demographic characteristics and the history of suicide attempt and sexual violence with a specific standardized questionnaire. Addictive disorders were identified with the Fagerström and CAGE questionnaires and with the DSM-IV-R diagnostic criteria for nicotine, alcohol, cannabis opiates, and cocaine abuse and dependence disorders. Lastly, we studied sensation seeking with the Zuckerman scale and impulsivity with the Barratt scale. Results: Linear regression identified four factors associated with aggressive behavior: male gender (odd ratio = 12.8), history of sexual violence (odd ratio = 3.6), Fagerström score (odd ratio = 1.3), number of cigarettes smoked each day (odd ratio = 1.16). Patients with nicotine use or dependence had significantly higher levels of OAS scores. This difference was not observed between patients with or without alcohol dependence. OAS scores were correlated to the number of cigarettes smoked each day and to Fagerström scores. Patients with a higher level of sensation seeking and impulsivity also had higher OAS scores. Conclusion: A typical schizophrenic patient at risk of showing aggressive behavior is a man, who smokes and presents a history of sexual violence. PMID:24027539

Associations between adolescent health-related quality of life (HRQoL), bullying, and aggression are not well understood. We used baseline data from a large-cluster randomized school trial to study the relationship between HRQoL, bullying experience, and other demographic factors. Cross-sectional self-reported questionnaires collected pre-randomization from the on-going INCLUSIVE trial. The questionnaires were completed in the classroom. The Gatehouse Bullying Scale measured bullying victimization and the Edinburgh Study of Youth Transitions and Crime school misbehavior subscale (ESYTC) measured aggressive behaviors. HRQoL was assessed using the Child Health Utility 9 Dimensions (CHU-9D) and general quality of life using the Pediatric Quality of Life Inventory (PedsQL). Participants were a cohort of year 7 students (age 11-12 years) from 40 state secondary schools in England. Descriptive statistics for the CHU-9D and PedsQL were calculated using standard methods with tests for differences in median scores by sex assessed using quantile regression. Correlation between HRQoL measures was conducted using Spearman's rank correlation coefficients. Predictors of HRQoL were identified using univariate and multiple regressions. A total of 6667 students filled out the questionnaire. The CHU-9D was correlated with the PedsQL (0.63, p < 0.001). The multivariable regression results suggest that if students were bullied frequently and upset it resulted in a decrement in CHU-9D scores of (-0.108) and fall in PedsQL score of (-16.2). The impact of the antisocial/aggressive behavior on the ESYTC scale resulted in a utility decrement of -0.004 and fall of -.5 on the PedsQL. Adolescents' involvement in bullying and aggression is a strong correlate of HRQoL. These data have important implications for the potential cost-effectiveness of reducing bullying and aggression in schools.

Cognitions are starting to receive more prominence as important when examining a number of factors including the topography of challenging behaviour. This study examined the relationships between maternal stress, challenging behaviour (aggressive and self-injurious behaviours) and parental cognitions and specifically whether maternal cognitions mediated the effect of challenging behaviour on parenting stress. 46 mothers of children and young adults with ID completed questionnaires regarding their child's challenging behaviour, maternal cognitions and stress. Significant correlations were found between challenging behaviour and maternal stress. The overall mediation models for aggression and self-injurious behaviour were significant. The Challenging Behaviour Perception Questionnaire: Consequences client subscale was the only independent significant mediator for both behaviours. Cognitions do play an important part in mediating the relationship between challenging behaviour and stress. Further research is needed to examine the similarities and differences between the mediation models for aggression and self-injurious behaviour.

The present research was designed to examine the psychometric properties of Chinese versions of the Self Report Driver Behavior Aggression and Assertiveness subscales, the Driving Vengeance Questionnaire, and the Violent Driving Questionnaire. Study 1 found that the all scales demonstrated good internal consistency, with alphas ranging from .76 to .87 and that assertive driving was related to demerit points received over the past 12 months while driver aggression and violence were linked to collisions over the past 12 months. Study 2 found that the scales exhibited reasonable test-retest reliability, with correlations ranging from .82 to .89. Finally, Study 3 showed that each scale was predicted by other dangerous driving attitudes and behaviors, similar to the original versions. The consistency between the translated and original scales, the implications for use in a Chinese sample, and the uniformity of actions in the traffic environment across cultures are discussed.

This study examines the relationship between parenting style, androgen levels, and measures of physical and indirect aggression. Peer ratings of aggression were obtained from 159 eight-year-old children (89 boys and 70 girls). Parenting styles (authoritative, authoritarian or permissive) were assessed using the Parenting Styles and Dimensions Questionnaire (PSDQ).Saliva samples were obtained from children and assayed for testosterone and androstenedione concentrations. A regression analysis revealed that high testosterone levels were associated with a higher level of physical aggression in boys with authoritarian mothers. Testosterone was also found to moderate the relationship between father's authoritarian parenting and physical aggression in girls, with both moderate and high levels being significant. In relation to indirect aggression, moderate and high levels of testosterone were associated with higher levels of this type of aggression in girls with permissive mothers. Our results highlight the importance of taking into account the interaction of biological and psychosocial variables when investigating aggressive behavior. © 2014 Wiley Periodicals, Inc.

When do normative beliefs about aggression predict aggressive behavior? An application of I3 theory.

PubMed

I(3) theory assumes that aggressive behavior is dependent on three orthogonal processes (i.e., Instigator, Impellance, and Inhibition). Previous studies showed that Impellance (trait aggressiveness, retaliation tendencies) better predicted aggression when Instigator was strong and Inhibition was weak. In the current study, we predicted that another Impellance (i.e., normative beliefs about aggression) might predict aggression when Instigator was absent and Inhibition was high (i.e., the perfect calm proposition). In two experiments, participants first completed the normative beliefs about aggression questionnaire. Two weeks later, participants' self-control resources were manipulated either using the Stroop task (study 1, N = 148) or through an "e-crossing" task (study 2, N = 180). Afterwards, with or without being provoked, participants played a game with an ostensible partner where they had a chance to aggress against them. Study 1 found that normative beliefs about aggression negatively and significantly predicted aggressive behavior only when provocation was absent and self-control resources were not depleted. In Study 2, normative beliefs about aggression negatively predicted aggressive behavior at marginal significance level only in the "no-provocation and no-depletion" condition. In conclusion, the current study provides partial support for the perfect calm proposition and I(3) theory. © 2015 Wiley Periodicals, Inc.

In the present era, delinquency in children and adolescents is undoubtedly a difficult and upsetting issue attracting the attention of many experts such as psychologists, sociologists, and criminologists. These experts often try to answer why a number of children and adolescents engage in various crimes such as aggressive and anti-social crimes. They also try to find out how these crimes can be prevented. The present study investigates the effectiveness of mindfulness-based cognitive therapy training (MBCT) in reducing aggression in a juvenile correction and rehabilitation center of Zahedan province during years 1991 to 1992. This experimental study included an experimental and a control group with a pretest, posttest, and follow-up approach. The Buss and Perry aggression questionnaire (1992) was used for data collection. The sample group included 22 (10 experimental and 12 control groups) adolescent males in a juvenile correction and rehabilitation center of Zahedan province who were selected through a census method. Using a matching method based on the pre-test scores of the aggression questionnaire, they were then divided into two equivalent categories and were randomly assigned to the two groups. Mindfulness-based cognitive training took the group training in 8 sessions administered on experimental group. The follow-up test was conducted two weeks after the end of the posttest sessions. The results were analyzed using ANCOVA. The results of ANCOVA showed that mindfulness-based cognitive training could significantly reduce aggression during posttest and follow-up test phases in the experimental group, compared to the control group (P < 0.01). Moreover, the results indicated the effectiveness of this method in significantly reducing anger, physical aggression, and hostility during posttest and follow-up test phases (P < 0.05). However, no significant reduction was observed in the verbal aggression subscale. According to the results of the present study, mindfulness-based cognitive training seems to be effective for reducing aggressive behaviors.

China has the highest excess of male births in the world at 118 to every 100 female, with a current excess of 20 million men of reproductive age. The impact on the psychological well-being of the large numbers of men who will never marry is unclear. This study was carried out to test the hypothesis that older never-married men are more predisposed to depression, low self-esteem and aggression. The study was a cross-sectional survey using a self-completion questionnaire conducted in high sex ratio rural areas of Yunnan and Guizhou provinces. The tools used were the Beck Depression Inventory, Rosenberg's Self-Esteem Scale and the Bryant-Smith Aggression questionnaire. A total of 1,059 never-married men and 1,066 married men aged 30-40 completed questionnaires. Never-married men were financially poorer and had lower education levels than married ones. After adjusting for age, education and income, never-married men were significantly more likely to have lower self-esteem scores (P < 0.001), higher depression scores (P < 0.001), higher aggression scores (P < 0.001) and were more likely to have suicidal thoughts or wishes (P < 0.001) than married men. The high prevalence of severe depression and suicide ideation in these men is of particular concern. In rural China mental health services are currently very sparse, but rural doctors could be trained to use a check score to identify severe depression, and refer as appropriate to specialist services.

Verbal aggression and swearing are the most frequently encountered violence in the health care industry. Nurses are the most frequent victims. Not known is the incidence and impact of swearing against nurses in China. (a) Develop a Chinese version of the Nursing Swearing Impact Questionnaire; (b) report the preliminary findings from the use of the tool. Using a translation-back translation procedure, focus groups and expert review, followed by a survey of 32 participants. The Chinese version of the Nursing Swearing Impact Questionnaire has been developed, and cultural differences and different attitudes toward verbal aggression and swearing in disparate groups and workplaces have been highlighted. This is the first Chinese tool to research nurses' perspectives and experiences of swearing in the workplace. Nurses in China face serious challenges, and the impact of swearing on nurses requires more attention.

Perceptions of Parenting Practices as Predictors of Aggression in a Low-Income, Urban, Predominately African American Middle School Sample.

PubMed

Murray, Kantahyanee W; Haynie, Denise L; Howard, Donna E; Cheng, Tina L; Simons-Morton, Bruce

This research examined the relation between early adolescent aggression and parenting practices in an urban, predominately African American sample. Sixth graders (N = 209) completed questionnaires about their overt and relational aggressive behaviors and perceptions of caregivers' parenting practices. Findings indicated that moderate levels of parental expectations for peaceful solutions at Time 1 were associated with a lower likelihood of overt aggression at Time 2. Furthermore, findings suggest that when caregivers' support and knowledge of adolescents' whereabouts were relatively low or when caregivers' exerted high psychological control, moderate levels of parental expectations for peaceful solutions protected early adolescents against engagement in both overt and relational aggression. The implications of the findings for schools and other youth violence prevention settings are discussed.

Orue, Izaskun; Calvete, Esther

2012-02-01

The aim of this study was to evaluate the mediating role of the justification of violence schema in the relationship between exposure to violence and reactive and proactive aggressive behavior. We differentiated between direct and indirect exposure in four contexts: home, neighborhood, school and TV. A total of 675 children, aged between 8 and 12 years, participated in the study. They answered questionnaires about exposure to violence, justification of violence, and proactive and reactive aggressive behavior in two waves six months apart. The results showed that witnessing violence at home and on TV predicted aggressive behavior, and this relationship was mediated by the justification of violence. Victimization in all contexts predicted aggressive behavior and this relationship was generally mediated by the justification of violence.

A case-control study was conducted to investigate associations between organophosphate pesticide (OP) exposure, aggression, impulsivity, and attempted suicide. Questionnaires were used to collect information; impulsivity and aggression were measured by the Barratt Impulsivity Scale (BIS) and the Aggression Inventory (AI). A greater number of OP symptoms was associated with an increased odds of a suicide attempt after adjusting for marital status and income (OR = 1.45; CI 1.14-1.86). Attempted suicide was significantly associated with high impulsivity scores (means: 72.4 vs. 60.6, P < 0.0001) and high aggression scores (means: 38.5 vs. 26.1, P < 0.0001). Suicide attempters had a higher number of OP exposure symptoms than controls and scored higher on scales of impulsivity and aggression.

In this study were examined associations among physical education teachers' verbal aggressiveness as perceived by students and students' intrinsic motivation and reasons for discipline. The sample consisted of 265 Greek adolescent students who completed four questionnaires, the Verbal Aggressiveness Scale, the Lesson Satisfaction Scale, the Reasons for Discipline Scale, and the Intrinsic Motivation Inventory during physical education classes. Analysis indicated significant positive correlations among students' perceptions of teachers' verbal aggressiveness with pressure/ tension, external reasons, introjected reasons, no reasons, and self-responsibility. Significant negative correlations were noted for students' perceptions of teachers' verbal aggression with lesson satisfaction, enjoyment/interest, competence, effort/importance, intrinsic reasons, and caring. Differences between the two sexes were observed in their perceptions of teachers' verbal aggressiveness, intrinsic motivation, and reasons for discipline. Findings and implications for teachers' type of communication were also discussed and suggestions for research made.

This short report presents preliminary data on the role of emotional intelligence (EI) in moderating the relationship between psychopathy and aggression in a nonforensic sample. A sample of 109 volunteer men was administered the Psychopathic Personality Inventory-Revised (PPI-R), the Reactive-Proactive Aggression Questionnaire, and the Mayer-Salovey-Caruso emotional intelligence Test in individual sessions. Correlation and moderation analyzes showed that, at low levels of EI (in terms of strategic ability to understand and manage one's own and others' emotions), people scoring high on the total PPI-R and impulsivity dimension seemed to be both reactively and proactively aggressive. By contrast, at high levels of strategic ability, the relationships between psychopathy and aggression were no longer significant. These preliminary results encourage further investigation into the role of EI ability in mitigating aggressive outcomes in psychopathic subjects. © 2017 American Academy of Forensic Sciences.

Aggression and risk of future violence in forensic psychiatric patients with and without dyslexia.

Selenius, Heidi; Hellström, Ake; Belfrage, Henrik

2011-05-01

Dyslexia does not cause criminal behaviour, but it may worsen aggressive behaviour tendencies. In this study, aggressive behaviour and risk of future violence were compared between forensic psychiatric patients with and without dyslexia. Dyslexia was assessed using the Swedish phonological processing battery 'The Pigeon'. The patients filled in the Aggression Questionnaire, and trained assessors performed the risk assessments using HCR-20 version 2. Patients with dyslexia self-reported more aggressive behaviour compared with those without dyslexia. There was only a nearly significant tendency (p = 0.06) for the patients with dyslexia to receive higher scores in the HCR-20 compared with the patients without dyslexia, and phonological processing skills did not significantly predict aggression or risk of future violence. However, regression analyses demonstrated that poor phonological processing skills are a significant predictor of anger, which in turn significantly predicts risk of future violence.

The present study examined the direct and indirect relationships between parenting processes (parental closeness, parental monitoring, and parental peer approval), low self-control, and aggression. Participants were 546 adolescents aged 14-18 attending state high schools in Turkey. Participants completed a questionnaire that included measures of parenting processes, self-control, and aggression. Findings provided evidence of both direct and indirect effects of maternal and paternal parenting processes on aggression through low self-control. Specifically, results showed that maternal closeness, paternal peer approval and both maternal and paternal monitoring were positively and directly related to low self-control, and indirectly related to aggression through low self-control. Together, parenting processes and low self-control explained 21% of the variance in aggression. Implications for self-control theory and directions for future research are discussed.

Vida, Péter; Halász, József; Gádoros, Júlia

2013-01-01

Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

Aggression in residential youth care institutions is a frequent problem. The present short-term longitudinal study examined individual and institutional predictors of aggression in a group of 198 adolescents placed in open, semi-secure and secure residential institutions from the perspective of the importation and deprivation model. A total of 198 adolescents in residential youth care filled in questionnaires regarding group climate and aggression with a 3 month interval. Hierarchical multiple regression analyses were performed to test the degree to which individual and contextual factors predict aggression. Very limited support was found for the effect of contextual factors; only repression showed a trend, predicting direct aggression, while gender composition of the living groups yielded a small effect. Girls placed in same-gender groups showed lower levels of indirect (relational) aggression compared to adolescents placed in mixed-gender or boys-only groups, even when controlled for gender and initial levels of aggression. Type of institution (i.e., level of security) did not predict differences in aggression. In particular individual characteristics of the adolescents were associated with later aggression, including initial levels of aggression, showing substantial 3 months stability, age and gender of the adolescents. These findings are in line with research showing that aggression is relatively stable. Very limited support for environmental effects was found.

Car driver attitudes, perceptions of social norms and aggressive driving behaviour towards cyclists.

The interaction of car drivers and cyclists is one of the main causes of cycle incidents. The role of attitudes and social norms in shaping car drivers' aggressive behaviour towards cyclists, is not well understood and merits investigation. A sample of 276 drivers completed an online questionnaire concerning their attitudes towards cyclists, attitudes towards risky driving, perception of social norms concerning aggressive driving towards cyclists, and the frequency with which they engage in such aggressive driving behaviours. The results showed that attitudes towards cyclists, as well as social norm perceptions concerning aggressive driving towards cyclists, were associated with aggressive driving towards cyclists. Negative attitudes towards cyclists were more pronounced in non-cyclists than cyclists and their association with aggressive driving behaviour was stronger in cyclists than non-cyclists. The perception of social norms concerning aggressive driving towards cyclists had a stronger association with aggressive driving in non-cyclists than cyclists. Attitudes towards risk taking did not affect aggressive driving towards cyclists. These findings can inform campaigns that aim to improve cyclist and car driver interaction on the roads, making them safer to use for cyclists. Copyright © 2015 Elsevier Ltd. All rights reserved.

Problematic alcohol use as a risk factor for cyber aggression within romantic relationships.

2018-06-06

Cyber aggression has emerged as a modern form of intimate partner violence which has yet to undergo sufficient research necessary to identify risk factors that may increase the likelihood or severity of cyber aggressive behavior toward a relationship partner. Prior research offers contradictory findings pertaining to the relationship between problematic alcohol use and cyber aggression. We recruited 100 (40 female) adult participants through online crowdsourcing to complete a series of questionnaires assessing traditional partner violence, cyber aggression, and problematic alcohol use. Forty-two percent of the sample reported perpetrating cyber relational aggression and 35% reported perpetrating cyber privacy invasion during the year prior to study participation. Traditional partner violence was associated with both forms of cyber aggression. Problematic alcohol use was only associated with privacy invasion after accounting for demographic factors and traditional partner violence. Cyber aggression was prevalent among the current adult sample. Results suggest that problematic alcohol use is a risk factor for cyber privacy invasion but not cyber relational aggression. Findings add to and clarify the nascent, conflicting results that have emerged from prior research on alcohol-related cyber aggression.

The present study focused on the impact of gender and gender stereotype traits (i.e., masculinity, femininity) on cyber aggression perpetration utilizing different technologies (i.e., social-networking sites, gaming consoles, mobile phones) and behaviors (i.e., cyber relational aggression, cyber verbal aggression, hacking). Participants included 233 eighth graders (108 female; M age = 13.26, SD = 0.36) from two middle schools in the Midwestern United States. Adolescents completed questionnaires on their endorsement of masculinity and femininity traits as well as how often they engaged in cyber aggression perpetration (i.e., cyber relational aggression, cyber verbal aggression, hacking) through mobile phones, social-networking sites, and gaming consoles. Findings indicated that boys and girls with more feminine traits engaged in more cyber relational aggression through social-networking sites and mobile phones, while boys and girls who endorsed more masculine traits perpetrated this behavior and cyber verbal aggression more often through online gaming. In addition, these boys and girls engaged in more hacking through all technologies when compared with girls and boys who reported more feminine traits. Results of this study indicate the importance of delineating gender stereotype traits, behaviors, and technologies when examining cyber aggression perpetration.

Scotland has a particular problem with alcohol, and the links between intimate partner abuse (IPA) and alcohol appear stronger here than elsewhere across Europe. This study explored differences in alcohol use, related aggression and relationship conflict across a number of groups: men convicted for intimate partner abuse, men convicted of general offences and men recruited from community sports teams. Participants (n = 64) completed three questionnaires exploring their experiences of alcohol use (Alcohol Use Disorders Identification Test, AUDIT); alcohol and aggression (Alcohol Related Aggression Questionnaire, ARAQ-28), and relationship conflict (Revised Conflict Tactics Scale, CTS-2). There were significant differences across the groups in terms of AUDIT and ARAQ-28 scores, IPA and general offenders scored higher than the community sample. CTS-2 scores showed significant differences: both offender groups reported more use of negotiation and psychological abuse, than the community men, and IPA offenders reported causing more physical harm than either general offenders or the community sample. ARAQ-28 scores correlated with psychological abuse for general offenders. Alcohol use was very high across all groups, but the community group did not endorse an aggression-precipitating view of alcohol and did not report high IPA. Discussed is the need for cross-cultural research to explore putative mediators and moderators in the relationship between alcohol, aggressiveness and IPA.

Aggression in people with epilepsy (PWE) is not well understood. We investigated interictal aggression in PWE and clarified predictors and the interrelationships among them. This was a case-control study. Eligible subjects who consecutively visited the epilepsy clinic completed several questionnaires including the Aggression Questionnaire (AQ), the Revised Stigma Scale (RSS), the Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), and the Generalized Anxiety Disorder-7 (GAD-7). PWEs had higher overall AQ scores and anger and hostility subscale scores than controls. Patients with uncontrolled epilepsy also had higher physical and verbal aggression subscale scores than controls. Univariate analyses revealed associations between the overall AQ score and job, household income, marriage, antiepileptic drug (AED) load, seizure control, co-administration of psychiatric drugs, the RSS score, the K-NDDI-E score, and the GAD-7 score. Multivariate analyses indicated that the strongest predictor for the overall AQ score was the RSS score (β=0.346, p<0.001), followed by the GAD-7 score (β=0.244, p=0.003), and the K-NDDI-E score (β=0.172, p=0.047). The RSS score exerted a direct effect on the overall AQ score under the influences of the GAD-7 score and the K-NDDI-E score. The GAD-7 score also exerted a direct effect on the overall AQ score, but the K-NDDI-E score only had an indirect effect on the overall AQ score through the RSS score. The degree of interictal aggression is higher in PWE than controls. Perceived stigma is a critical factor for aggression under the influence of depression and anxiety.

The moderating role of empathy in the association between parental support and adolescent aggressive and delinquent behavior.

PubMed

Van der Graaff, Jolien; Branje, Susan; De Wied, Minet; Meeus, Wim

2012-01-01

The present two-wave longitudinal study addressed the role of affective empathy and parental support in aggressive and delinquent behavior in a sample of 323 adolescents (158 boys, 165 girls). Self-report questionnaires were used to assess affective empathy, perceived support from parents, delinquency, and aggression. Guided by theories on children's differential susceptibility to socialization, we expected adolescents with different levels of empathy to vary in their responsiveness to parental support. In agreement with our hypothesis, empathy moderated the relation of perceived parental support with aggressive and delinquent behavior. Controlling for the effect of gender and for the stability of aggression and delinquency, higher perceived parental support was predictive of lower levels of aggression at age 15, but only for adolescents high in empathy. Remarkably, adolescents low in empathy not only appeared to benefit less from parental support, but even showed more aggression and delinquency at age 15 when they perceived their parents to be more supportive at age 14. © 2012 Wiley Periodicals, Inc.

Controversies remain over the safety and efficacy of vitamin E (i.e., α-tocopherol) supplementation use for the prevention of prostate cancer (CaP); however, associations of different tocopherol forms and CaP aggressiveness have yet to be examined. This study examined whether food intake of tocopherols, vitamin E supplement use, and adipose tissue biomarkers of tocopherol were associated with CaP aggressiveness among African-American (AA, n = 1,023) and European-American (EA, n = 1,079) men diagnosed with incident CaP. Dietary tocopherols were estimated from a food frequency questionnaire, supplement use from questionnaire/inventory, and biomarkers from abdominal adipose samples measured using high-performance liquid chromatography. Odds ratios (ORs) and 95% confidence intervals (95%CIs) were estimated from logistic regression comparing high-aggressive CaP to low/intermediate aggressive CaP, adjusting for covariates. Dietary intakes of α-and δ-tocopherol were related inversely to CaP aggressiveness among EAs [OR (95%CI), highest versus lowest quartile: α-tocopherol, 0.34 (0.17-0.69), P(trend)  = 0.006; δ-tocopherol, 0.45 (0.21-0.95) P(trend)  = 0.007]. Inverse associations between dietary and supplemental α-tocopherol and CaP aggressiveness were observed among AAs, though these did not reach statistical significance [OR (95%CI), highest versus lowest quartile: dietary α-tocopherol, 0.58 (0.28-1.19), P(trend)  = 0.20; supplemental α-tocopherol, 0.64 (0.31-1.21) P(trend)  = 0.15]. No significant association was observed between adipose tocopherol levels and CaP aggressiveness [OR (95%CI), highest versus lowest quartiles of α-tocopherol for EAs 1.43 (0.66-3.11) and AAs 0.66 (0.27-1.62)]. The inverse associations observed between dietary sources of tocopherols and CaP aggressiveness suggests a beneficial role of food sources of these tocopherols in CaP aggressiveness. © 2015 Wiley Periodicals, Inc.

To evaluate (a) the association between Internet addiction and aggressive behaviors, as well as the moderating effects of gender, school, and depression on this association; and (b) to evaluate the association between Internet activities and aggressive behaviors. A total of 9405 adolescents were recruited into this study and completed the questionnaires. Their aggressive behaviors, with or without Internet addiction, Internet activities, demographic data, with or without depression, self-esteem, family function, and the watching of violent TV were assessed. The results demonstrated that after controlling for the effects of shared associated factors and watching violent TV programs, adolescents with Internet addiction were more likely to have aggressive behaviors during the previous year. The association was more significant among adolescents in junior high schools than in senior high/vocational schools. Online chatting, adult sex Web viewing, online gaming, online gambling, and Bulletin Board System were all associated with aggressive behaviors. The results suggest that preventive programs for aggressive behaviors should pay attention to Internet addiction among adolescents. Also, intervention to prevent the effects of Internet addiction on aggressive behaviors should be conducted as early as possible.

Emotionally dependent subjects may engage in controlling, restrictive, and aggressive behaviours, which limit their partner's autonomy. The underlying causes of such behaviours are not solely based on levels of aggression, but act as a mean of maintaining the subject's own sense of self-worth, identity, and general functioning. The aim of the paper is to explore the correlation between affective dependency and reactive/proactive aggression and to evaluate individual differences as predisposing factors for aggressive behaviour and emotional dependency. The Spouse-Specific Dependency Scale (SSDS) and the Reactive Proactive Questionnaire (RPQ) were administered to a sample of 3375 subjects. In the whole sample, a positive correlation between emotional dependency and proactive aggression was identified. Differences with regard to sex, age group, and geographical distribution were evidenced for the scores of the different scales. A fundamental distinction between reactive and proactive aggression was observed, anchoring proactive aggression more strictly to emotional dependency. Sociocultural and demographical variables, together with the previous structuring of attachment styles, help to determine the scope, frequency, and intensity of the demands made to the partner, as well as to feed the fears of loss, abandonment, or betrayal.

There is a need for instruments that can be used in correctional settings to measure changes in aggressive behaviors over a limited time period. This study aimed to validate an instrument (the Prison Adjusted Measure of Aggression, PAMA) that assesses specifically the past month's aggressive behaviors and is adapted for use in correctional facilities. The psychometric properties of the self-rated and interview versions of the PAMA were explored and compared to those of two well-established measures of aggression: The Staff Observation Aggression Scale (SOAS); and the self-rate Aggression Questionnaire-Revised Swedish Version (AQ-RSV). The study group comprised 93 male and 59 female inmates, who were followed for two months. During the study, the prevalence of aggressive acts was observed and reported by SOAS. On two occasions, at monthly intervals, subjects reported their own aggressive behaviors using AQ-RSV and the self-report version of the PAMA; also, a psychologist conducted interviews according to PAMA. This study's main finding was that the self-rated version of PAMA is a valid measure of different types and dimensions of aggression (physical and verbal aggression, hostility) and has acceptable psychometric properties. Therefore, PAMA could potentially be of value for use in correctional services evaluating aggression managing treatment interventions. Copyright © 2018 The Authors. Published by Elsevier B.V.

The aim of the present study was to verify that the level of tolerance for aggression is higher in a collective context than in an individual context (polarization effect), and to test the association between moral disengagement, team and self-attitudes toward aggression, and tolerance and realization of aggressive acts in Swiss male soccer and ice hockey. In individual or collective answering conditions, 104 soccer and 98 ice hockey players viewed videotaped aggressive acts and completed a questionnaire, including measures of the perceived legitimacy of videotaped aggression, of the teammates, coach, and self attitudes toward transgressions (modified TNQ), of the moral disengagement in sport (modified MDSS-S), and of self-reported aggressive behavior. A multilevel analysis confirmed a strong polarization effect on the perception of instrumental aggression, the videotaped aggressive acts appearing more tolerated in the collective than in the individual answering condition. Using a structural equation modeling, we found that the moral disengagement, which mediates the effects of perceived coach and ego attitudes toward transgressions, correlates positively with the tolerance of hostile aggression within teams, and with the level of aggressive acts reported by the participants.

Adolescents' Perceptions of Popularity-Motivated Behaviors, Characteristics, and Relationships in Cyberspace and Cyber Aggression: The Role of Gender.

Wright, Michelle F

2017-06-01

Research is increasingly revealing that adolescents utilize electronic technologies to promote and/or maintain their social standing among their peer group. Little is known about whether adolescents' perceptions of popularity-motivated behaviors, characteristics, and relationships in cyberspace are associated with popularity-motivated cyber relational aggression. It is also unclear how gender might impact these associations, especially considering that adolescent girls and boys differ in regard to the type of behaviors, characteristics, and relationships they believe contribute to popularity. To this end, this study examined the potential moderating effect of gender on the association between adolescents' perceptions of popularity-motivated behaviors, characteristics, and relationships in cyberspace and their engagement in popularity-motivated cyber relational aggression over 1 year, from seventh to eighth grade. There were 217 eighth graders (51 percent female; M age = 12.13) from three middle schools in a large Midwestern city in the United States included in this research. They completed questionnaires on their popularity-motivated behaviors, characteristics, and relationships in cyberspace and their perpetration of popularity-motivated cyber relational aggression during the seventh grade. One year later, they completed the perpetration of popularity-motivated cyber relational aggression questionnaire. The results revealed that the association between popularity-motivated behaviors, characteristics, and relationships in cyberspace and the perpetration of popularity-motivated cyber relational aggression was stronger for girls, while such an association was not found for boys. These findings indicate the importance of considering cyberspace as an environment in which adolescents can enhance their social standing among peers from their school.

Gender specific personality profiles in association with the level of aggressive antisocial behavior in offenders have not been previously investigated. In the present study we analyzed data collected from 65 male and 50 female offenders using structured protocols regarding criminal history (by criminal register data), trait aggression (by the Life History of Aggression (LHA) questionnaire), and personality profiles (by the Temperament and Character Inventory (TCI)). Prison inmates differed significantly on several personality dimensions, most pronouncedly were they characterized with low character maturity (low scores in the Self-Directedness and Cooperativeness dimensions of TCI) when compared to gender and age matched controls of the general population. The majority of offenders scored distinctively high on trait aggression. There were moderate to strong associations between the personality dimensions and each of the subscales of LHA (Aggression, Self-directed Aggression and Antisocial behavior). These associations were stronger in the female offender sample. Trait aggression could be best explained by a model, which included male gender, younger age, high novelty seeking temperament and low character maturity. Our results suggest that therapies aiming at strengthening self-governance and increasing cooperativeness (focusing on character maturity) may alleviate aggressive antisocial behavior in offenders.

Androgen levels, parenting styles and aggressive behavior in 5-6-year-old boys and girls. This study explores the relationship between androgen levels, parenting styles, and physical, verbal, and indirect aggression measures in 5-6-year-old children. 129 children (60 boys and 69 girls) were assessed in relation to their aggression levels using a peer-rating technique. Parents completed the Parenting Styles and Dimensions Questionnaire, from which the different parenting styles were obtained. Testosterone, androstenedione and dehydroepiandrosterone (DHEA) were measured using an enzymoimmunoassay technique in saliva samples. A regression analysis indicated that the directive mother-androstenedione interaction at the age of 5 was predictive of physical aggression at the age of 6. In specific terms, the results showed that, in boys with high androstenedione levels, directive maternal behavior is associated with physical aggression. The results are subsequently discussed in light of postulates related to parenting characteristic of developmental psychology and we suggest a potential link of our results with the hypothesis of maternal dominance.

Suicide is one of the leading causes of death worldwide, mortality from suicide being approximately 2%. Attempted suicide appears to be a major risk factor for suicide completion. Anger, aggression and impulsivity are personality traits associated with suicide attempt. In this study we analysed a part of a previously reported sample in order to test anger, impulsivity and temperament/character scales as predictors of aggression and self-aggression in suicide attempters and to compare anger- and aggression-related traits between impulsive and premeditated suicide attempts as well as between violent and non-violent suicide methods. One-hundred-eleven consecutively admitted inpatients with a lifetime history of attempted suicide were assessed for anger (State-Trait Anger Expression Inventory, STAXI), aggression (Questionnaire for Measuring Factors of Aggression, FAF) and temperament/character (Temperament and Character Inventory, TCI). Higher aggression scores, as measured by FAF, were predicted by being male, meeting criteria for borderline personality disorder and having higher angry temperament scores as assessed by STAXI; low cooperativeness was also associated with aggression but not after controlling for STAXI scales. TCI dimensions associated with self-aggression were high harm avoidance, high impulsivity and low self-directedness; state anger, inwardly directed anger and inhibition of aggression were also predictors of self-aggression. In conclusion, impulsivity and harm avoidance have emerged as temperament dimensions independently associated with self-aggressive tendencies in personality. Such interactions could explain the correlation between temperament and suicidality but further research is needed. Anger and self-directedness appear to have some effects on suicide attempt.

Does perceived parental rejection make adolescents sad and mad? The association of perceived parental rejection with adolescent depression and aggression.

To research the association of perceived parental rejection to adolescent depression and aggression. This study focused on 1329 Dutch junior high and high school students (47.9% males and 52.1% females; age range 10-19 years) that completed depression, aggression and perceived parental rejection questionnaires. The data were analyzed by structural equation modeling that assumed a relationship between perceived parental rejection and adolescent aggression, as mediated by adolescent depression. Perceived parental rejection, mediated through adolescent depression, explains aggressive behaviors of adolescents, as tested by a mediation model. Additionally, the fit of this mediation model is somewhat enhanced when direct paths from perceived parental rejection to aggression are included. Further analysis demonstrates that these effects are also somewhat dependent on the gender and the age of the adolescents, as would be expected in light of previous studies of these cohorts. The study of perceived parental rejection should receive the same attention in the research of the development of both adolescent depression and aggression, as has been the case for adolescent peer rejection.

This study examined the fitness of a path model on the relationship among stress, self-esteem, aggression, depression, suicidal ideation, and violent behavior for adolescents. The subjects consisted of 1,177 adolescents. Data was collected through self-report questionnaires. The data was analyzed by the SPSS and AMOS programs. Stress, self-esteem, aggression, and depression showed a direct effect on suicidal ideation for adolescents, while stress, self-esteem, and aggression showed an indirect effect on suicidal ideation for adolescents. Stress, self-esteem, aggression, and suicidal ideation showed a direct effect on violent behavior for adolescents, while stress, self-esteem, aggression, and depression showed an indirect effect on violent behavior for adolescents. The modified path model of adolescent's suicidal ideation and violent behavior was proven correct. These results suggest that adolescent's suicidal ideation and violent behavior can be decreased by reducing stress, aggression, and depression and increasing self-esteem. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes reducing stress, aggression, and depression and increasing self-esteem in order to decrease adolescents' suicide ideation and violence.

This study examined the influences of online gaming on sociability and aggression in real life. It was hypothesized that the effects of online gaming would differ depending on the interaction style of the online-gamers. Online-gamers in Japan (n = 1 477) were asked to respond to questionnaires that measured interaction style during online gaming, the effects of sociability and aggression, as well as social and individual orientation in real life. Factor analysis of the scores for interaction style extracted five factors. Covariance structure analysis indicated that sociable interactions such as "Broadening relations" and "Feeling of belonging" promoted sociability in real life. In addition, "Release from daily hassles" promoted sociability and decreased aggression. In contrast, non-sociable and aggressive interactions decreased sociability and increased aggression. The results also suggested that a social orientation in real life promoted sociable interactions during game playing, while an individual orientation promoted non-sociable and aggressive interactions. These results supported the hypotheses and suggested that online gaming resulted in positive outcomes for those who are socially, but negative outcomes for those who are not.

Incremental prediction and moderating role of the perceived emotional intelligence over aggressive behavior.

The aim of this research was to explore the influence of Perceived Emotional Intelligence (PEI) on aggression dimensions (Physical Aggression, Verbal Aggression, Hostility, and Anger) above and beyond the effects of gender, age, and personality traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience), as well as the moderating role of PEI on the relationship between personality and aggressive behavior, among young adults. The Trait Meta-Mood Scale, the Big-Five Inventory, and the Aggression Questionnaire were administered to a 313 Spanish community sample, comprised of both males (39.0%) and females (61.0%), ranging from 14 to 69 years old (X = 24.74; SD = 9.27). Controlling the effects of age, gender, and personality, PEI dimensions (Attention, Clarity and Repair) accounted for 3% of the variance (p < .05) in Verbal Aggression and Hostility. Interaction analysis showed that all PEI subscales moderated the relationship between four out of the Big-Five personality dimensions (Extraversion, Agreeableness, Neuroticism, and Openness to Experience) and the aggression dimensions. Particularly, the interaction between Attention and Extraversion and between Clarity and Neuroticism were significant predictors of Total Aggression (b = .67, t(313) = 2.35, p < .05; b = -.71, t(313) = -2.50, p < .05). The results show evidence of the predictive and incremental validity of PEI dimensions on aggressive behavior among young adults and of the moderating role of PEI on the personality-aggression relationship.

With the frequent occurrence of campus violence, scholars have devoted increasing attention to college students' aggression. This study aims to estimate the prevalence of aggression in Chinese university students and identify factors that could influence their aggression. We can thus find methods to reduce the incidence of college students' aggression in the future. A multi-stage stratified sampling procedure was used to select university students (N = 4565) aged 16-25 years in Harbin. The Aggression Questionnaire, the Adolescent Self-Rating Life Events Checklist and the Social Support Revalued Scale were used to collect data. Females reported lower levels of aggression than males (p < .001). A multiple linear regression analysis was conducted to determine the influence of factors of aggression, and the model was highly significant (R 2  = .233, Ad R 2  = .230, p < .01). The results show that the aggression is affected by gender, family-level and school-level variables. Aggression scores are significantly correlated with not only family-level or school-level variables independently, but their combination as well. We find that the risk factors for aggression include a dissatisfying profession, higher levels of study pressure, poor parental relationships, poor interpersonal relationships, the presence of siblings, punishment, health maladjustment, less subjective support, and lower levels of utilization of social support.

2015-10-01

The perpetration and receipt of electronic aggression have largely been assessed with self-report questionnaires. Using a sample of 573 adolescents, the current study compared the psychometric properties of a peer-nomination measure of electronic aggression and victimization to the more widely used self-report approach. Estimates of the reliability, stability, and concordance of peer- and self-report assessments were adequate, mirroring those from research on aggressive exchanges in school. Analyses of validity and utility revealed that peer-nominations, compared to self-reports, provide overlapping and distinct information on adolescents' social, emotional, and academic adjustment. Overall, these findings provide evidence that peer-nominations are a reliable, valid, and useful means for measuring electronic aggression and victimization. Future work will benefit from their incorporation into multi-method assessments. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

Childhood physical abuse and aggression: Shame and narcissistic vulnerability.

2016-01-01

This study examined narcissistic vulnerability and shame-proneness as potential mediators between childhood physical abuse (CPA) and adult anger and aggression. Participants were 400 undergraduate students, 134 of whom had a history of CPA. All participants completed self-report questionnaires assessing history of CPA, shame-proneness, narcissistic vulnerability, physical aggression, trait anger, and hostility. Results indicated abused participants were more angry and aggressive and experienced higher levels of shame-proneness and narcissistic vulnerability than nonabused participants. Multiple mediation analyses showed that narcissistic vulnerability, but not shame-proneness, partially mediated the relation between abuse and physical aggression. However, narcissistic vulnerability and shame-proneness both emerged as partial mediators between abuse and the anger and hostility variables. These findings suggest that narcissistic vulnerability and shame-proneness may function as mediators of adjustment following childhood maltreatment. Study limitations and recommendations for future research are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to determine the prediction of aggression among Iranian adolescent based on theory of planned behavior (TPB) as a theoretical framework. Methods: In this cross-sectional study, conducted in Yasuj County, south of Iran, during 2011, a total of 256 male adolescents, were randomly enrolled. Participants filled out a self-administered questionnaire. Data were analyzed by SPSS version 21 using bivariate correlations, and linear regression statistical tests at 95% signifi­cant level. Result:The three predictor variables of 1) attitude, 2) subjective norms, and 3) perceived behavioral control, accounted for 40% of the variation in the outcome measure of the aggression intention. Besides, intention accounted for 15% of the variation in the outcome measure of the aggression behavior. There was a sig­nificant correlation between drug abuse and alcohol consumption, have friend drug user, unprotect sex and parents divorced with aggression (P< 0.05). Conclusions: Designing intervention to reduction positive attitude and subjective norms toward aggressive behavior among adolescents could be usefulness result to aggression prevention.

This study examined the relationships among attitude toward violence, self-esteem, emotion dysregulation, anger, and aggression in community men and women and male inmates. Overall, 166 community men, 197 community women, and 100 male inmates completed a battery of questionnaires containing self-reported measures. Self-esteem and attitude toward violence were significant predictors of aggressive behavior, with emotion dysregulation mediating the relationship between self-esteem and the criterion variable. Anger mediated the relationship between emotion dysregulation and aggressive behavior only among community people. Among men, inmates reported a more favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, more aggressive behaviors, and a lower tendency to get angry. Women showed a less favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, and a higher tendency for anger than men, while no differences emerged for aggressive behavior. These findings suggest that self-related constructs and emotion regulation strategies represent key processes associated with aggressive behavior among all participants, while the role of anger is more prominent in community people. To reduce aggressive tendencies, treatment and prevention interventions might increase self-esteem, emotion regulation skills, and one's ability to direct anger toward other goals. Moreover, programs aimed at changing attitudes toward violence could be useful.

Social cognition in Intermittent Explosive Disorder and aggression

Social-emotional information processing (SEIP) was assessed in individuals with current DSM-5 Intermittent Explosive Disorder (IED: n = 100) and in healthy (n = 100) and psychiatric (n = 100) controls using a recently developed and validated self-rated questionnaire. SEIP vignettes depicted both direct aggressive and relationally aggressive scenarios of a socially ambiguous nature and were followed by questions assessing subjects' reactions and judgments about the vignettes. IED subjects differed from both healthy and psychiatric controls in all SEIP components. While hostile attribution was highly related to history of aggression, it was also directly correlated with negative emotional response. Further analysis revealed that this component, as well as response valuation and response efficiency, rather than hostile attribution, best explained history of aggressive behavior. A reformulated SEIP model, including self-reported history of childhood trauma, found that negative emotional response and response efficiency were the critical correlates for history of aggressive behavior. Psychosocial interventions of aggressive behavior in IED subjects may do well to include elements that work to reduce the emotional response to social threat and that work to restructure social cognition so that the tendency towards overt, or relationally, aggressive responding is reduced.

The theory of planned behavior, materialism, and aggressive driving.

PubMed

Efrat, Kalanit; Shoham, Aviv

2013-10-01

Aggressive driving is a growing problem worldwide. Previous research has provided us with some insights into the characteristics of drivers prone to aggressiveness on the road and into the external conditions triggering such behavior. Little is known, however, about the personality traits of aggressive drivers. The present study proposes planned behavior and materialism as predictors of aggressive driving behavior. Data was gathered using a questionnaire-based survey of 220 individuals from twelve large industrial organizations in Israel. Our hypotheses were tested using structural equation modeling. Our results indicate that while planned behavior is a good predictor of the intention to behave aggressively, it has no impact on the tendency to behave aggressively. Materialism, however, was found to be a significant indicator of aggressive driving behavior. Our study is based on a self-reported survey, therefore might suffer from several issues concerning the willingness to answer truthfully. Furthermore, the sampling group might be seen as somewhat biased due to the relatively high income/education levels of the respondents. While both issues, aggressive driving and the theory of planned behavior, have been studied previously, the linkage between the two as well as the ability of materialism to predict aggressive behavior received little attention previously. The present study encompasses these constructs providing new insights into the linkage between them. Copyright © 2013 Elsevier Ltd. All rights reserved.

Types of aggressiveness and catecholamine response in essential hypertensives and healthy controls.

1991-01-01

Relationships between plasma catecholamine responses, and levels and types of aggression in hyper- and normotensives were investigated by analyses of data obtained in a large psychophysiological experiment on 97 hypertensives (EH) and 98 normotensives (CO) each. Subjects were divided according to levels (high vs low) and types (repressed vs manifest) of aggressiveness according to self rating questionnaire scores. Their plasma catecholamine responses to defined stressors indicating sympathetic arousability were compared by four factor analyses of covariance adjusting for age. Repressed aggression was significantly more frequent among male EH, whereas manifest aggression was significantly more frequent among the male COs. High as compared to low hostility was associated with significantly elevated values of plasma epinephrine in EH but not in CO. The immediate norepinephrine stress response was blunted but showed a delayed increase during the subsequent period of rest in high aggressives of both the EH and CO group, a pattern particularly pronounced in repressed aggressive hypertensives. Neither cardiovascular reactions nor speed of performance were observed to be substantially different in subjects of repressed and of manifest hostility. It was concluded that aggression in general is characterized by a delayed norepinephrine stress response and that an association with high epinephrine is typical for aggressiveness in hypertensives. Repressed hostility, however, does not produce a sympathomedullary pattern substantially different from that of manifest aggression thus casting doubt on the physiological significance of repression claimed by Alexander.

Many epidemiological studies have examined fruit and vegetable consumption in relation to the risk of urothelial cell carcinoma (UCC) of the bladder, but results are inconsistent. The association between fruit and vegetable consumption and UCC risk may vary by bladder tumour aggressiveness. Therefore, we examined the relation between fruit and vegetable consumption and the risk of aggressive and non-aggressive UCC in the European Prospective Investigation into Cancer and Nutrition (EPIC). After 8.9 years of follow-up, 947UCC were diagnosed among 468,656 EPIC participants. Of these, 421 could be classified as aggressive UCC and 433 as non-aggressive UCC cases. At recruitment, fruit and vegetable consumption was assessed by validated dietary questionnaires. Multivariable hazard ratios were estimated using Cox regression stratified by age, sex and center and adjusted for smoking status, duration and intensity of smoking, and energy intake. Total consumption of fruits and vegetables was not associated with aggressive UCC nor with non-aggressive UCC. A 25 g/day increase in leafy vegetables and grapes consumption was associated with a reduced risk of non-aggressive UCC (hazard ratio (HR) 0.88; 95%confidence interval (CI) 0.78-1.00 and HR 0.87; 95%CI 0.77-0.98, respectively), while the intake of root vegetables was inversely associated with risk of aggressive UCC (HR 0.87; 95%CI 0.77-0.98). Our study did not confirm a protective effect of total fruit and/or vegetable consumption on aggressive or non-aggressive UCC. High consumption of certain types of vegetables and of fruits may reduce the risk of aggressive or non-aggressive UCC; however chance findings cannot be excluded. Copyright © 2012 Elsevier Ltd.

Patient aggression affects healthcare quality and, in extreme situations, may even lead to medical malpractice. Little is known, however, about the specific distribution of health care professionals' exposure to patient aggression in various countries. The aim of this study was to assess the exposure of various professional groups of healthcare personnel to patient aggression, and to identify potential determinants (medical profession, age, gender, professional experience and employment at outpatient/inpatient healthcare units) of this exposure. The study was performed between January 2008 - December 2009 in northeastern Poland, and included 1,624 healthcare workers (493 nurses, 504 midwives, 501 physicians and 126 medical rescue workers). Exposure to eight forms of patient aggression was assessed using the MDM Mobbing Questionnaire. Using a raised voice was the most frequently observed form of aggression in all groups, whereas the least frequent form of aggression encountered was the use of direct physical violence. In inpatient healthcare units, the intensity of patient aggression was encountered most by nurses and medical rescue workers, followed by physicians and midwives. In outpatient healthcare units, medical rescue workers experienced significantly higher levels of aggression when compared to other professional groups. Significant differences in mean aggression intensity experienced in inpatient and outpatient healthcare units were observed only in nurses and physicians. Furthermore, no significant effects of gender were observed on the intensity of patient aggression. Nurses are most exposed to different forms of patient aggression, with verbal attacks being most prevalent. Nurses employed at inpatient healthcare units experienced aggression more frequently than those working in outpatient healthcare units.

Rationale Child abuse and neglect are universal risk factors for delinquency, violence, and aggression; this phenomenon is known as the cycle of violence. Additional factors—psychopathy, impulsiveness, and disruptions in the hypothalamic–pituitary–adrenal (HPA) axis—play a role in aggressive behavior but have rarely been examined in the same conceptual and experimental framework. Objectives We sought to examine the above-mentioned risk factors for aggression in a prospective study employing psychopharmacologic and psychometric techniques. Methods Sixty-seven adult participants were given an acute dose of 20 mg cortisol in a placebo-controlled, within-subject, counter-balanced dosing design. Salivary cortisol was measured at baseline and at regular intervals across a 5 h testing period. Following dosing, state-aggressive behavior was measured by a laboratory task, the Point-Subtraction Aggression Paradigm. History of child abuse/−neglect, psychopathy, impulsivity, and a trait measure of aggression were assessed through self-report questionnaires. Results Using multiple regression, a model including abuse/neglect, psychopathy, impulsivity, and baseline cortisol explained 58 % of the variance in trait aggression and 26 % of the variance in state aggression. Abuse/neglect predicted diminished HPA-axis reactivity and HPA-axis reactivity showed a trend toward predicting state and trait aggression, although it was not a significant mediating variable between abuse/neglect and aggression. Conclusions The results indicate that child maltreatment, psychopathy and HPA-axis reactivity interact to provide a confluence over aggressive behavior, and intervention efforts need to consider all these factors.

Aggression affects academic learning and emotional development, can damage school climate and if not controlled early and may precipitate extreme violence in the future. (1) To determine the magnitude and types of aggressive behavior in school children. (2) To identify the influence of age and sex on aggressive behavior. A cross-sectional study was conducted in Anandanagar High School, Singur village, West Bengal. Participants were 161 boys and 177 girls of classes VII to IX. The students were asked to complete a self-administered questionnaire indicating the types of aggressive behavior by them in the previous month and to assess themselves with reference to statements indicating verbal/physical aggression. Overall, 66.5% of the children were physically aggressive in the previous month: Boys 75.8%, girls 58.2% (P = 0.001); 56.8% were verbally aggressive: Boys 55.2%, girls 61% (P = 0.97). Verbal indirect passive aggression was more common among girls (55.3%) than among boys (22.3%) (P = 0.000 [1.17E(-09)]). Boys were more liable to physical aggression, viz. 60.2% of the boys would hit on provocation compared with only 9% of the girls (P = 0.000 [6.6E(-23)]). Regarding attributes indicating verbal aggression, girls were more argumentative (63.8%) than boys (55.2%) (P = 0.134) and disagreeing (41.8%) compared with boys (33.5%) (P = 0.145). With increasing age/class, physical direct active aggression decreased while physical indirect passive and verbal indirect passive aggression increased. No classes had been taken on anger control/management by school the authorities. Aggressive behavior was common both among boys and girls. Life skills education/counseling/classroom management strategies are recommended.

The current study explored how individual differences in endorsement of aggressive behaviors and thoughts relate to individual levels of tolerance and prejudice toward immigrants and established prejudice correlates such as social dominance orientation (SDO) and ethnic out-groups ratings among adolescents. Participants (N = 141; Age M = 16.08, 68% girls) completed the Readiness for Interpersonal Aggression Inventory, the Tolerance and Prejudice Questionnaire, and measures of SDO and ethnic out-groups ratings. Results indicated that higher individual endorsement of aggression was related to higher prejudice and SDO and lower tolerance and ethnic out-groups ratings. Patterns of endorsement of aggression related to habitual and socially determined aggressive acts or stable needs to hurt others as a source of satisfaction were significantly correlated with prejudice. Conversely, the relationship between prejudice and endorsement of impulsive actions lacking of emotional control resulted was less marked. The results highlight how in the cognitive spectrum of prejudice, individual levels of endorsement of aggression may play a significant triggering role during adolescence. These findings may have implications for future studies and interventions aimed at reducing prejudice already in young ages. PMID:28344674

Gene-environment interactions that moderate aggressive behavior have been identified independently in the serotonin transporter (5-HTT) gene and monoamine oxidase A gene (MAOA). The aim of the present study was to investigate epistasis interactions between MAOA-variable number tandem repeat (VNTR), 5-HTTlinked polymorphism (LPR) and child abuse and the effects of these on aggressive tendencies in a group of otherwise healthy adolescents. A group of 546 Chinese male adolescents completed the Child Trauma Questionnaire and Youth self-report of the Child Behavior Checklist. Buccal cells were collected for DNA analysis. The effects of childhood abuse, MAOA-VNTR, 5-HTTLPR genotypes and their interactive gene-gene-environmental effects on aggressive behavior were analyzed using a linear regression model. The effect of child maltreatment was significant, and a three-way interaction among MAOA-VNTR, 5-HTTLPR and sexual abuse (SA) relating to aggressive behaviors was identified. Chinese male adolescents with high expression of the MAOA-VNTR allele and 5-HTTLPR “SS” genotype exhibited the highest aggression tendencies with an increase in SA during childhood. The findings reported support aggression being a complex behavior involving the synergistic effects of gene-gene-environment interactions. PMID:28203149

Do beliefs about gender roles moderate the relationship between exposure to misogynistic song lyrics and men's female-directed aggression?

2017-04-01

Although independent lines of research have identified misogynistic lyrical content and traditional gender role beliefs as reliable predictors of men's female-directed aggression, more research is needed to understand the extent to which these variables may function in synthesis to potentiate aggression. In the current study, men (N = 193), who completed questionnaires relevant to their conformity to masculine norms and level of hostile and benevolent sexism, were exposed to either misogynistic or neutral lyrics before having the opportunity to shock an ostensible female confederate in a bogus reaction time task that, in effect, measured aggression. Results indicated that misogynistic lyrics and hostile sexism significantly predicted both unprovoked and provoked aggression against a female target. Contrary to expectations, moderating effects of gender role beliefs on the relationship between misogynistic lyrics and men's aggression were not found. Implications are discussed in terms of the costs of misogyny in media for women's lives. Aggr. Behav. 43:123-132, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

This paper examines male and female individual differences in situational triggers of aggressive responses (STAR) in three countries as well as cross-cultural sex differences in trait aggression (aggression questionnaire, AQ). Convenience sampling was employed (university students) for the descriptive correlational study (Poland N = 300, 63% female, mean age 21.86, SD = 2.12; UK N = 196, 60% female, mean age 20.48, SD = 3.79; Greece N = 299, 57% female, mean age 20.71, SD = 4.42). The results showed that the STAR scale is an equivalent construct across all three countries. Overall, females were more sensitive to both provocation (SP) and frustration (SF) than males. When controlling for trait aggression, Polish and Greek females scored similarly in SP and higher than UK females. No sex differences in SP or SF were found in the UK sample. Additionally, Polish participants scored the highest in SP. Furthermore, when trait aggression was removed, the Greek participants were most sensitive to frustration, whereas Polish and English participants' SF did not differ. We discuss the results with regard to intercultural differences between investigated countries. © 2014 International Union of Psychological Science.

Finger length ratio (2D:4D) correlates with physical aggression in men but not in women.

PubMed

Bailey, Allison A; Hurd, Peter L

2005-03-01

Finger length ratio (2D:4D) is a sexually dimorphic trait. Men have relatively shorter second digits (index fingers) than fourth digits (ring fingers). Smaller, more masculine, digit ratios are thought to be associated with either higher prenatal testosterone levels or greater sensitivity to androgens, or both. Men with more masculine finger ratios are perceived as being more masculine and dominant by female observers, and tend to perform better in a number of physical sports. We hypothesized that digit ratio would correlate with propensity to engage in aggressive behavior. We examined the relationship between trait aggression, assayed using a questionnaire, and finger length ratio in both men and women. Men with lower, more masculine, finger length ratios had higher trait physical aggression scores (r(partial) = -0.21, N = 134, P = 0.028). We found no correlation between finger length ratio and any form of aggression in females. These results are consistent with the hypothesis that testosterone has an organizational effect on adult physical aggression in men.

Objective Cardiovascular reactivity to laboratory stressors was investigated as (a) a moderator of associations of partner aggression with affective functioning, alcohol problems, and parenting, and (b) a consequence of partner aggression. Method Cohabiting adult couples (N = 453) with 3- to 7-year-old children were recruited by random digit dialing and completed questionnaires assessing couple physical aggression, discipline practices, anger, stress, depressive symptoms, and problem alcohol use. Heart rate and blood pressure were measured at rest and in response to laboratory stressors (mental arithmetic and video presentations of family conflict). Results Males’ physical aggression more strongly predicted women’s affective functioning and alcohol problems when the women had greater cardiovascular reactivity. This pattern did not extend to men. Physical victimization was associated with lower cardiovascular reactivity. Conclusions The present results provide partial support for the Biological Sensitivity to Context model of Boyce and Ellis (2005) and suggest that incorporating the moderating influence of biological reactivity may improve the precision of models of the effects of aggression on adult adjustment.

Pedophilia is characterized by sexual attraction to prepubescent children. Despite the extensive literature documenting the pervasive and pernicious effects of childhood sexual abuse, there is surprisingly little psychiatric literature on pedophilia and its etiology remains enigmatic. In recent years, the psychiatric literature on the phenomenology, neurobiology, and treatment of impulsive-aggressive disorders has grown significantly. As some investigators have conceptualized pedophilia as an impulsive-aggressive disorder, it is of interest whether recent advances in the study of impulsive-aggressive disorders might shed light on pathological mechanisms underlying pedophilia. In the following study, 20 male subjects with a DSM-IV diagnosis of pedophilia, heterosexual type were recruited from an outpatient facility for sexual offenders and compared to 24 demographically similar control subjects. Groups were compared on three personality instruments--the Millon Clinical Multiaxial Inventory-II (MCMI-II), the Temperament and Character Inventory (TCI), and the Dimensional Assessment of Personality Impairment-Questionnaire (DAPI-Q)--to assess for select impairment in impulsive-aggressive personality traits. Pedophiles showed severe and pervasive personality impairment relative to controls. Although there was evidence of impulsivity, the findings do not suggest a predominance of impulsive-aggressive traits, and in fact provide evidence of inhibition, passive-aggression, and harm avoidance. The notion of "compulsive-aggression" in pedophilia is proposed.

Benzodiazepine-related aggression has received insufficient research attention, in particular little is known about the motivational factors which may contribute to the development of this paradoxical response. The revised Reinforcement Sensitivity Theory provides a theoretical framework from which to understand the relevant underlying motivational processes. The current study aimed to identify the role of approach and avoidance motivational tendencies in the occurrence of benzodiazepine-related aggression. Data regarding benzodiazepine and other substance use, approach and avoidance motivation, and general and physical aggressive behaviour were collected via self-report questionnaires. Participants were a convenience sample (n=204) who reported using benzodiazepines in the previous year. Participants were primarily male (62.7%), aged 18-51 years old. Hierarchical multiple regressions indicated that general and physical aggression were predicted by alprazolam use and Drive, a facet of approach motivation. Overall, lower diazepam use significantly predicted higher levels of general aggression. However, when diazepam-preferring participants were examined in isolation of the larger sample (23.5% of sample), problematic (dependent) diazepam use was associated with greater aggression scores, as was dependence risk for alprazolam-preferring participants (39.7% of sample). The findings highlight the importance of motivational factors and benzodiazepine use patterns in understanding benzodiazepine-related aggression, with implications for violent offender rehabilitation.

The influence of adverse early attachment experiences on the development of aggressive sexual behavior has been demonstrated. Nonetheless, there is a gap in the literature regarding the conceptualization of this behavior according to developmental psychopathology models. The purpose of the present study was to investigate a potential association between Early Maladaptive Schemas (EMSs) and aggressive sexual behavior. A total of 166 male college students participated in the study. Participants were divided into two comparative groups according to data from the Sexual Experiences Survey-Short Form Perpetration (SES-SFP): Group of individuals with history of aggressive sexual behavior (N = 37) and Group of individuals without history of aggressive sexual behavior (N = 129). Aggressive sexual behavior was measured by the SES-SFP, and EMSs were measured by the Young Schema Questionnaire (YSQ-S3). Results showed that students who have committed any form of sexually aggressive behavior exhibited significantly higher levels of EMSs from the Disconnection and Rejection domain (namely, Mistrust/Abuse schema), from the Impaired Autonomy and Performance domain (namely, Dependence/Incompetence schema), and from the Overvigilance and Inhibition domain (namely, Negativity/Pessimism schema). These preliminary findings suggest that the EMSs were associated with aggressive sexual behavior, but further investigation is warranted. © 2012 International Society for Sexual Medicine.

This study aimed to examine the mediating role of anger in the relationship between automatic thoughts and physical aggression in adolescents. The study included 224 adolescents in the 9th grade of 3 different high schools in central Burdur during the 2011-2012 academic year. Participants completed the Aggression Questionnaire and Automatic Thoughts Scale in their classrooms during counseling sessions. Data were analyzed using simple and multiple linear regression analysis. There were positive correlations between the adolescents' automatic thoughts, and physical aggression, and anger. According to regression analysis, automatic thoughts effectively predicted the level of physical aggression (b= 0.233, P < 0.001)) and anger (b= 0.325, P < 0.001). Analysis of the mediating role of anger showed that anger fully mediated the relationship between automatic thoughts and physical aggression (Sobel z = 5.646, P < 0.001). Anger fully mediated the relationship between automatic thoughts and physical aggression. Providing adolescents with anger management skills training is very important for the prevention of physical aggression. Such training programs should include components related to the development of an awareness of dysfunctional and anger-triggering automatic thoughts, and how to change them. As the study group included adolescents from Burdur, the findings can only be generalized to groups with similar characteristics.

Gene-environment interactions that moderate aggressive behavior have been identified in association with the MAOA (monoamine oxidase A) gene. The present study examined the moderating effect of MAOA-VNTR (variable number of tandem repeats) on aggression behavior relating to child abuse among Chinese adolescents. A sample of 507 healthy Chinese male adolescents completed the Child Trauma Questionnaire-Short Form (CTQ-SF) and Youth Self-report of the Child Behavior Checklist. The participants' buccal cells were sampled and subjected to DNA analysis. The effects of childhood abuse (CTQ-SF scores), MAOA-VNTR [high-activity allele (H) versus low-activity allele (L)], and their interaction in aggressive behaviors were analyzed by linear regression. Child maltreatment was found to be a significant independent factor in the manifestation of aggressive behavior, whereas MAOA activity was not. There was a significant interaction between MAOA-VNTR and childhood maltreatment in the exhibition of aggressive behaviors. In the context of physical or emotional abuse, boys in the MAOA-L group showed a greater tendency toward aggression than those in the MAOA-H group. Aggressive behavior arising from childhood maltreatment is moderated by MAOA-VNTR, which may be differentially sensitive to the subtype of childhood maltreatment experienced, among Chinese adolescents.

Accumulating evidence suggests that genetic and environmental factors may influence aggression susceptibility. However, the etiology of aggressive behavior remains unknown. Compared to some extensively studied candidate genes of aggression, very little is known about the OXTR gene. The objective of this study was to determine whether OXTR genetic variants were associated with aggression risk and whether these polymorphisms showed interactive effects with childhood maltreatment on aggression in Chinese adolescents. A total of 996 participants including 488 cases and 488 controls were selected in our study. Aggression, childhood maltreatment were measured by self-reported questionnaire. Buccal cells were collected. Genotyping was performed using SNPscan. Logistic regressions were used to estimate both main effects of OXTR polymorphisms and the interactive effects with childhood maltreatment on aggressive behavior. Participants who carried the rs237885 TT genotypes in OXTR had a higher risk of aggression compared to those who carried GG or GT genotypes under the recessive model (OR=1.40, 95% CI, 1.04-1.89) after controlling for potential confounders. In addition, we also found that the polymorphism had a synergic additive interaction with childhood physical abuse on the aggression risk. The subjects in the present study were only males, thus our findings and conclusions could not be generalized to females. The present study provides evidence that OXTR genetic variants may contribute to aggression susceptibility. Moreover, this is the first study reporting significant interactive effects of OXTR polymorphism and childhood physical abuse on aggressive behavior in Chinese adolescents.

Chen, Frances R; Raine, Adrian; Granger, Douglas A

2018-01-20

This study tests a biosocial model of the link between testosterone and proactive-reactive aggression in youth at varying levels of harsh discipline. Given that proactive aggression is used to gain power and status and the importance of social learning in its formation, we hypothesized that testosterone would be associated with proactive aggression at higher levels of harsh discipline, and that this relationship would be more pronounced in boys than girls. Participants (n = 445; 50% male; M age = 11.92 years; 80% African-American) and their caregivers completed questionnaires including demographics, conflict tactics, and proactive-reactive aggression. Youth also provided a saliva sample for testosterone. Analyses revealed an interaction between testosterone and harsh discipline on proactive aggression in both boys and girls, and an interaction between testosterone and harsh discipline on reactive aggression in boys only. For those experiencing high levels of harsh discipline, testosterone was positively associated with proactive aggression, with the magnitude of the association increasing as harsh discipline increased. For below average levels of harsh discipline, there were protective effects of high testosterone for boy's reactive aggression and for girl's proactive aggression. The findings support basic tenets of the biosocial model which suggest that links between testosterone and aggressive behavior are dependent on contextual forces, highlighting the complex relationship between hormones, social context, and aggression. Novel findings include protective effects of high testosterone for those exposed to low levels of harsh discipline. Findings are discussed in light of the context-contingency effect and also within the differential susceptibility framework.

Increasing antisocial and violent behaviors in adolescents and young adults present serious challenges for public health. Children with persistent high levels of aggressiveness are often associated with developing conduct disorders later in life. Early detection of highly aggressive children and sociodemographic risk-modifying factors are important for developing effective preventive strategies. The present study was undertaken to assess levels of aggressiveness for detecting highly aggressive children in sample populations of primary school children in an urban setting and determine significant biosociocultural risk-modifying factors in this scenario. The study was conducted during August-September, 2015 in 5 primary schools of South Delhi Municipal Corporation. Sociodemographic data on 2080 students were collected. Overall aggressiveness scores (OA-Scores) were estimated using a self-report questionnaire in Hindi. Categorizing students according to their OA-Scores, the data revealed that highly aggressive children constituted 4.3% of the study population. Analysis showed significant influence of (a) gender: boys displayed higher levels of aggressiveness compared to girls; (b) dietary pattern: omnivores showed higher aggressiveness than vegetarians; and (c) school environment: boys in mixed-sex (coeducational) schools displayed lower aggressiveness than from single-sex schools. Statistically significant influences of religion (Hindu/Muslim) and family type (joint/nuclear) on aggressiveness profiles were not noticeable. Vegetarian diets and mixed-sex education act as protective factors in the development of aggressiveness in children, especially among boys. Extending investigations to populations differing in geography and cultural backgrounds are warranted to verify present results.

The aim of this study was, on the one hand, to present/display the Spanish version of diverse instruments that assess Empathy, Prosocial behavior, Aggressiveness, Self-efficacy and Personal and social responsibility, and, on the other hand, to analyze which of these variables could predict responsibility. Participants were 822 pupils, ages 8 to 15 years, who studied in 11 educational centres of the Valencian Community. Measures include Spanish versions of the Index of Empathy for Children and Adolescents, Prosocial Behaviour, and Physical and Verbal Aggression, the Multidimensional Scale of Perceived Self-Efficacy, and the Contextual Self-Responsibility Questionnaire. Through structural equation modelling (SEM), the results showed positive relationships between Prosocial behaviour, Empathy, Self-efficacy, and Responsibility; and negative relationships between Aggressiveness and Responsibility. The results and implications for education are discussed.

Concern for personal safety is a pervasive stressor for many women. Developing competencies in physical self-defense may empower women to engage more freely in daily activities with less fear. This study assessed the effects of physical self-defense training on multiple aspects of women's perceived self-efficacy and other self-reported personality characteristics. Training powerfully increased task-specific (self-defense) efficacy beliefs as well as physical and global efficacy beliefs. Training increased self-reported assertiveness, and posttraining decreases in hostility and aggression were found on several of the subscales of The Aggression Questionnaire (A. H. Buss & M. Perry, 1992), indicating that training did not have an aggression-disinhibiting effect. In the experimental condition, most of the effects were maintained (and some delayed effects appeared at follow-up.

We examined the roles of sensation seeking, risk taking, and moral reasoning in the development of reactive and proactive aggression. Data were drawn from a multiethnic, longitudinal study of children from Switzerland (N = 1571; 52 % male; assessed annually over 6 years; 7-years-old at Time 1). At all 6 time points, teachers reported children's reactive and proactive aggression via questionnaire. Children's sensation seeking (at Time 1) and risk taking (at Time 2) were assessed with two interactive computer tasks and their moral reasoning was assessed at Time 2 in response to four hypothetical vignettes depicting moral transgressions. Parallel process Latent Class Growth Analysis (PP-LCGA) identified six dual trajectories of reactive and proactive aggression. Children with either childhood-limited or adolescent-onset aggression showed high sensation seeking. Children with persistent, high levels of both reactive and proactive aggression across time showed high levels of sensation seeking and risk taking, as well as low levels of moral reasoning. Children with only high risk taking were more likely to display moderate levels of aggression across time. These findings highlight the shared and differential roles of sensation seeking, risk taking, and moral reasoning in the dual development of reactive and proactive aggression from mid-childhood to early adolescence. We discuss implications for common and tailored strategies to combat these aggression subtypes.

Nurses' attitudes about the causes and management of aggression affects their choice of intervention. We aimed to compare the attitudes held by patients and staff in a forensic mental health service with the Management of Aggression and Violence Attitudes Scale, and examine the factor validity of the tool in this setting by conducting a prospective comparative questionnaire survey. Staff (n = 72) and patient (n = 98) attitudes differed to a limited extent. Confirmatory factor analysis refuted the previously reported structure of the tool. Exploratory factor analysis suggested three underlying factors related to modifiability of aggression, hands on management, and hands off management. Patients were more optimistic than nurses about the modifiability of aggressive behaviour. Male patients and those with diagnoses other than personality disorder were significantly more likely to agree about modifiability than controls. Forensic inpatients recognize the need for the use of a range of techniques to prevent and manage aggression and violence, but selected groups are most likely to believe that aggression is modifiable. Prevention and management of aggression training should emphasize the modifiability of aggressive behaviour. The development of measures of modifiability and management style would assist in the evaluation of training and would offer new avenues for research. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

Background In contrast with an early implicit “facilitative hypothesis” of humor, a revised specificity hypothesis predicts that the benefits of humor depend on the specific style of humor used. Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being. Methods We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201) aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information. Results High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively) but both initiation competence (positively) and conflict management competence (negatively) predicted aggressive humor. Conclusion The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor. PMID:23180973

Adolescent risk-taking and aggressive behaviours are among the most visible forms of violence in society. A study was carried out to identify the prevalence and risk factors for aggression, violence and criminal behaviour among adolescents in Alexandria, Egypt. Using multistage, cluster sampling of families from all health districts in Alexandria, the mothers of 783 adolescents aged 11-19 years answered an Arabic version of the Mentor Research Institute screening questionnaire. Overall 26.9% of adolescents were assessed to be at high risk and 20.2% at extremely high risk of aggression and criminal behaviour. Living in urban/slum areas, male sex, low level of parents' education/occupation, exposure to violence within the family and changes in behaviour of any family member were associated with risk of aggression/violence. In multivariate analysis, the significant independent variables were adolescents' sex, presence of behavioural changes in the family, violence against brothers and sisters and substance abuse by any family member.

Brief report: Play fighting to curb self-reported aggression in young adolescents.

This study investigated the effects of play fighting on aggressive behaviors. It was hypothesized that the teaching of play fighting during physical education lessons could reduce self-reported aggression in a group of adolescents to a greater extent than playing volleyball (a low physical contact activity). Participants were 210 young adolescents (mean age = 13.27, SD = 0.48 years) from 10 classrooms that were randomly assigned to an 8-lesson play fighting session or to traditional volleyball lessons. They filled in the 12-item short version of the Aggression Questionnaire (AQ-12) pre- and post-interventions. The play fighting group showed a significant reduction in all the four subscales of the AQ-12 (Cohen d ranging from 0.61 to 0.67), while participants in the volleyball group did not. Results suggest that play fighting might provide useful contents in a physical education curriculum, with possible reduction in aggressive behavior.

Objective: The aim of the present study was to analyze the effects of a mindfulness training psycho-educative program on impulsivity and aggression levels in a sample of high school students. Methods: A randomized controlled trial with pre-test-post-test measurements was applied to an experimental group and a control group (waiting list). The Barratt Impulsivity Scale (BIS-11) Patton et al. (1995) and the Aggression Questionnaire (Buss and Perry, 1992) were used. Results: Statistical analyses showed a significant decrease in the levels of impulsivity and aggressiveness in the experimental group compared with the control group. These results have important implications for improving the level of academic engagement and self-efficacy of students and for reducing school failure. Conclusion: This is one of the first studies showing the effectiveness of mindfulness training at reducing impulsive and aggressive behaviors in the classroom. The efficacy of mindfulness-based programs is emphasized.

Correlative evidence suggests that testosterone promotes dominance and aggression. However, causal evidence is scarce and offers mixed results. To investigate this relationship, we administered testosterone for 48h to 41 healthy young adult men in a within-subjects, double-blind placebo-controlled balanced crossover design. Subjects played the role of responders in an ultimatum game, where rejecting a low offer is costly, but serves to destroy the proposer's profit. Such action can hence be interpreted as non-physical aggression in response to social provocation. In addition, subjects completed a self-assessed mood questionnaire. As expected, self-reported aggressiveness was a key predictor of ultimatum game rejections. However, while testosterone affected subjective ratings of feeling energetic and interested, our evidence strongly suggests that testosterone had no effect on ultimatum game rejections or on aggressive mood. Our findings illustrate the importance of using causal interventions to assess correlative evidence. Copyright © 2016. Published by Elsevier Inc.

Teachers promote student learning and well-being in school by establishing a supportive classroom structure. The term classroom structure refers to how teachers design tasks, maintain authority, and evaluate student achievement. Although empirical studies have shown the relation of classroom structure to student motivation, achievement, and well-being, no prior investigations have examined the influence of classroom structure on aggression among peers. The present study examined whether a supportive classroom structure has an impact on verbal and physical aggression. At two points in time, data were collected from 1680 students in Grades 5 to 7 using self-report questionnaires. The results of structural equation modeling revealed that a supportive classroom structure at Time 1 was associated with less perpetrated verbal aggression at Time 2, 9months later. This finding has practical relevance for teacher training as well as for aggression prevention and intervention among children. Copyright © 2012 Society for the Study of School Psychology.

Reactive aggression (RA) refers to angry responses to provocation or frustration, while proactive aggression (PA) denotes nonemotional, instrumental, and unprovoked aggression. The current study examined personality-related and cognitive correlates of both aggressive types. Respectively, the predictive values of antisocial personality disorder (ASPD), and of hostile interpretation bias, which is the tendency to interpret ambiguous stimuli in a hostile manner, were studied. The sample consisted of n = 37 male adult patients with mixed diagnoses and n = 29 male nonpatients that responded to vignettes and pictures of ambiguous situations, using both open and closed answer formats. ASPD was assessed by means of the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II), and the Reactive Proactive Questionnaire (RPQ) measured RA and PA. Results showed that although both RA and PA types were predicted by ASPD traits, RA was additionally predicted by a hostile interpretation bias. These findings suggest that reducing hostile bias is a promising avenue for clinical treatment of ASPD-patients high in RA.

Considerable research has investigated the deleterious effects of teachers responding aggressively to students who misbehave, but the mechanism underlying this dysfunctional behaviour remains unknown. This study investigated whether the mechanism underlying teacher aggression follows I 3 theory or General Aggression Model (GAM) metatheory of human aggression. I 3 theory explains exceptional, catastrophic events of human aggression, whereas the GAM explains common human aggression behaviours. A total of 249 Australian teachers participated in this study, including 142 primary school teachers (Mdn [age] = 35-39 years; Mdn [years teaching] = 10-14 years; 84% female) and 107 secondary school teachers (Mdn [age] = 45-49 years; Mdn [years teaching] = 15-19 years; 65% female). Participants completed four online self-report questionnaires, which assessed caregiving responsiveness, trait self-control, misbehaviour provocation, and teacher aggression. Analyses revealed that the GAM most accurately captures the mechanism underlying teacher aggression, with lower caregiving responsiveness appearing to indirectly lead to teacher aggression via higher misbehaviour provocation and lower trait self-control in serial, controlling for gender, age, years teaching, and current role (primary, secondary). This study indicates that teacher aggression proceeds from 'the person in the situation'. Specifically, lower caregiving responsiveness appears to negatively shape a teacher's affective, cognitive, and arousal states, which influence how they perceive and interpret student misbehaviour. These internal states, in turn, appear to negatively influence appraisal and decision processes, leading to immediate appraisal and impulsive actions. These results raise the possibility that teacher aggression is a form of countertransference. © 2017 The British Psychological Society.

Abstract Previous studies have reported associations between aggression and Internet addiction disorder (IAD), which has also been linked with anxiety, depression, and impulsiveness. However, the causal relationship between aggression and IAD has thus far not been clearly demonstrated. This study was designed to (a) examine the association between aggression and IAD and (b) investigate the mediating effects of anxiety, depression, and impulsivity in cases in which IAD predicts aggression or aggression predicts IAD. A total of 714 middle school students in Seoul, South Korea, were asked to provide demographic information and complete the Young's Internet Addiction Test (Y-IAT), the Buss–Perry Aggression Questionnaire, the Barratt Impulsiveness Scale-11, the State–Trait Anger Expression Inventory-2, the Beck Anxiety Inventory, the Beck Depression Inventory, and the Conners–Wells Adolescent Self-Report Scale. Three groups were identified based on the Y-IAT: the usual user group (n=487, 68.2%), the high-risk group (n=191, 26.8%), and the Internet addiction group (n=13, 1.8%). The data revealed a linear association between aggression and IAD such that one variable could be predicted by the other. According to the path analysis, the clinical scales (BAI, BDI, and CASS) had partial or full mediating effects on the ability of aggression to predict IAD, but the clinical scales had no mediating effect on the ability of IAD to predict aggression. The current findings suggest that adolescents with IAD seem to have more aggressive dispositions than do normal adolescents. If more aggressive individuals are clinically prone to Internet addiction, early psychiatric intervention may contribute to the prevention of IAD. PMID:25902276

Chronic methamphetamine (MA) use can lead to white matter (WM) changes and increased levels of aggression. While previous studies have examined WM abnormalities relating to cognitive impairment, associations between WM integrity and aggression in MA dependence remain unclear. Diffusion Tensor Imaging (DTI) was used to investigate WM changes in 40 individuals with MA dependence and 40 matched healthy controls. A region of interest (ROI) approach using tract based spatial statistics (TBSS) in FSL was performed. We compared fractional anisotropy (FA), mean diffusivity (MD), parallel diffusivity (λ║) and perpendicular diffusivity (λ┴) in WM tracts of the frontal brain. A relationship of WM with aggression scores from the Buss & Perry Questionnaire was investigated. Mean scores for anger (p < 0.001), physical aggression (p = 0.032) and total aggression (p = 0.021) were significantly higher in the MA group relative to controls. ROI analysis showed increased MD (U = 439.5, p = 0.001) and λ┴ (U = 561.5, p = 0.021) values in the genu of the corpus callosum, and increased MD (U = 541.5, p = 0.012) values in the right cingulum in MA dependence. None of the WM changes were significantly associated with aggression scores. This study provides evidence of frontal WM changes and increased levels of aggression in individuals with MA dependence. The lack of significant associations between WM and aggressive behaviour may reflect methodological issues in measuring such behaviour, or may indicate that the neurobiology of aggression is not simply correlated with WM damage but is more complex.

Mental disorders can be associated with suicidal or aggressive ideation and behavior, especially in the context of embitterment. The aim of this study is to investigate the types, prevalence, and dangerousness of aggressive and suicidal ideations associated with embitterment. When therapists from the department of behavioral medicine detected signs of embitterment, aggression, or suicidal thoughts in their patients, they routinely filled out a questionnaire on aggressive ideation, assessed the embitterment, and contacted a senior psychiatrist. Additionally, patients answered an embitterment scale. There were 127 patients (3.84% of all patients) with suicidal and/or aggressive ideation. They had an increased score of 2.93 (SD 0.74) on the embitterment scale, associated with personal vilification (62.7%), breach of trust (30.2%), public humiliation (25.4%), death/loss (5.6%), or attacks by another person (14.3%). We found that 83.5% of the patients harbored aggressive ideations; in 94.1% of this group, these were directed against the person who had caused the problem, 88.3% wanted to inflict severe damage, 38.8% to harm another person, 31.5% showed suicidal ideation, and 3.2% had fantasies of murder-suicide. Only 34.3% of the patients reported spontaneously about their current aggressive ideation. The limitations of the study are that the data come from an inpatient sample and patients were identified according to clinical judgement. Aggressive ideation is regularly associated with embitterment. This deserves the attention of therapists for the prevention of aggressive acts. © 2018 S. Karger AG, Basel.

Impulsive aggression has commonly been associated with a dysfunction of the serotonin (5-HT) system: many, but not all, studies point to an inverse relationship between 5-HT and aggression. As cerebral 5-HT4 receptor (5-HT4R) binding has recently been recognized as a proxy for stable brain levels of 5-HT, we here test the hypothesis in healthy men and women that brain 5-HT levels, as indexed by cerebral 5-HT4R, are inversely correlated with trait aggression and impulsivity. Sixty-one individuals (47 men) underwent positron emission tomography scanning with the radioligand [11C]SB207145 for quantification of brain 5-HT4R binding. The Buss–Perry Aggression Questionnaire (BPAQ) and the Barratt Impulsiveness Scale were used for assessment of trait aggression and trait impulsivity. Among male subjects, there was a positive correlation between global 5-HT4R and BPAQ total score (P = 0.037) as well as BPAQ physical aggression (P = 0.025). No main effect of global 5-HT4R on trait aggression or impulsivity was found in the mixed gender sample, but there was evidence for sex interaction effects in the relationship between global 5-HT4R and BPAQ physical aggression. In conclusion we found that low cerebral 5-HT levels, as indexed by 5-HT4R binding were associated with high trait aggression in males, but not in females. PMID:26772668

Family Risk Factors Associated With Aggressive Behavior in Chinese Preschool Children.

Jia, Shoumei; Wang, Ling; Shi, Yingjuan; Li, Ping

The study explored family predictors of aggressive behavior in preschool children in China. Using a stratified cluster sampling method, 1382 preschool children were recruited from ten kindergarten schools in Shanghai, China. Their parents completed the Child Behavior Checklist (CBCL)-aggression subscale, the Parent Behavior Inventory, the Family Environment Scale, and a demographic questionnaire. The mean age of the 1382 children was 4.97years (SD=.88), with 55.1% (762) boys, and 44.9% (620) girls. According to the CBCL, the prevalence of aggressive behavior in preschool children was 12.4%. Multivariate logistic regression analysis showed that family conflicts (OR = 1.231, 95% CI: 1.115-1.360), hostile/coercive parenting (OR = 1.083, 95% CI: 1.051-1.116), inconsistent parenting between grandparents and parents (OR = 1.658, 95% CI: 1.175-2.341), and more time spent watching TV (OR = 1.999, 95% CI: 1.568-2.550) significantly predicted aggressive behavior of children. Children with more family conflicts who experience hostile/coercive parenting were more likely to engage in aggressive behavior. Moreover, inconsistent parenting attitudes between grandparents and parents, and excessive TV exposure also contributed to childhood aggression. Given that the results of this study show a high prevalence of aggressive behavior in preschool children, future research must pay greater attention to this aspect. Family risk factors identified as relevant to children's aggression in this study provide avenues to develop family-focused strategies for curbing aggression in preschool children.

Individuals with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder report heightened levels of numerous risky and health-compromising behaviors, including aggressive behaviors. Given evidence that aggressive behavior is associated with negative substance use disorder treatment outcomes, research is needed to identify the factors that may account for the association between PTSD and aggressive behavior among patients with substance use disorder. Thus, the goal of this study was to examine the role of impulsivity dimensions (i.e., negative urgency, lack of premeditation, lack of perseverance, and sensation seeking) in the relations between probable PTSD status and both verbal and physical aggression. Participants were 92 patients in residential substance use disorder treatment (75% male; 59% African American; M age = 40.25) who completed self-report questionnaires. Patients with co-occurring PTSD-substance use disorder (vs. substance use disorder alone) reported significantly greater verbal and physical aggression as well as higher levels of negative urgency and lack of premeditation. Lack of premeditation and lack of perseverance were significantly positively associated with verbal aggression, whereas negative urgency, lack of premeditation, and lack of perseverance were significantly positively associated with physical aggression. The indirect relation of probable PTSD status to physical aggression through negative urgency was significant. Results highlight the potential utility of incorporating skills focused on controlling impulsive behaviors in the context of negative emotional arousal in interventions for physical aggression among patients with co-occurring PTSD-substance use disorder.

Chronic lead exposure is associated with neurological ill-health including anti-social behavior such as aggressive behavior. The main aim of this study was to examine the association between lead exposure at 13years old and dimensions of aggressive behavior during mid-adolescence. The study sample included 508 males and 578 females in mid-adolescence (age 14 to 15years) from the Birth to Twenty Plus cohort in Johannesburg, South Africa. Blood samples collected at age 13years were used to measure blood lead levels. Seventeen items characterizing aggression from the Youth Self Report questionnaire were used to examine aggressive behavior. Principal Component Analysis was used to derive composite variables from the original data for aggressive behavior; and data were examined for an association between blood lead levels and dimensionality of direct and indirect aggression and disobedience during mid-adolescence. We also examined the dimensions of aggression during mid-adolescence in relation to gender and socio-demographic factors. Blood lead levels ranged from 1 to 28.1μg/dL. Seventy two percent of males and 47.7% of females in the study had blood lead levels ≥5μg/dL. There was a positive association between elevated blood lead levels and direct aggression (p<0.05). Being male was positively associated with direct aggression (p<0.001) but, negatively associated with indirect aggression (p<0.001). Maternal education and age at birth were negatively associated with direct aggression during mid-adolescence. The significant association between elevated blood lead levels and direct aggressive behavior observed in this study may shed light on a possible environmental toxicological contribution to aggressive behavior in South African youth; and most importantly the type of aggressive behavior associated to lead exposure.

Aggression is a serious problem for both individuals and society. Despite progress in aggression research, its persistence among adolescents living in rural areas remains to be investigated. We evaluate the prevalence of aggression and the association between stressful life events and aggression in a nationwide, school-based sample of adolescents living in rural areas of China. A sample of 13,495 Chinese rural students (7065 boys and 6430 girls; 11-20 years old) was selected from 15 representative rural areas from 5 provinces in China using stratified randomized cluster sampling. Aggression, stressful life events, neglect, emotional management, social support, and demographic characteristics were assessed via self-report questionnaires. Multivariate logistic regressions were used to estimate the association of stressful life events and aggression after controlling for confounds. The prevalence of aggressive behavior among Chinese adolescents living in rural areas was 24.3%. Regression analyses indicated that the odds of aggression were negatively influenced by chronic long-term stressors related to interpersonal problems (OR=2.03, 95% CI [1.75-2.36]), health adaptation difficulties (OR=1.21, 95% CI [1.09-1.34]), and other troubles (OR=1.93, 95% CI [1.74-2.14]), even after adjustment for parental neglect, emotional management, social support, and other relevant factors. This study was cross-sectional; thus, it is necessary to validate the causal relationship between stressful life events and aggression via follow-up studies. Aggression was prevalent among Chinese adolescents living in rural areas, and interpersonal problems, health adaption difficulties, and other troubles were considered potential independent risk factors for aggression.

Reactive and proactive subtypes of aggression have been recognized to help parse etiological heterogeneity of this complex phenotype. With a heritability of about 50%, genetic factors play a role in the development of aggressive behavior. Imaging studies implicate brain structures related to social behavior in aggression etiology, most notably the amygdala and striatum. This study aimed to gain more insight into the pathways from genetic risk factors for aggression to aggression phenotypes. To this end, we conducted genome-wide gene-based cross-trait meta-analyses of aggression with the volumes of amygdala, nucleus accumbens and caudate nucleus to identify genes influencing both aggression and aggression-related brain volumes. We used data of large-scale genome-wide association studies (GWAS) of: (a) aggressive behavior in children and adolescents (EAGLE, N = 18,988); and (b) Magnetic Resonance Imaging (MRI)-based volume measures of aggression-relevant subcortical brain regions (ENIGMA2, N = 13,171). Second, the identified genes were further investigated in a sample of healthy adults (mean age (SD) = 25.28 (4.62) years; 43% male) who had genome-wide genotyping data and questionnaire data on aggression subtypes available (Brain Imaging Genetics, BIG, N = 501) to study their effect on reactive and proactive subtypes of aggression. Our meta-analysis identified two genes, MECOM and AVPR1A, significantly associated with both aggression risk and nucleus accumbens (MECOM) and amygdala (AVPR1A) brain volume. Subsequent in-depth analysis of these genes in healthy adults (BIG), including sex as an interaction term in the model, revealed no significant subtype-specific gene-wide associations. Using cross-trait meta-analysis of brain measures and psychiatric phenotypes, this study generated new hypotheses about specific links between genes, the brain and behavior. Results indicate that MECOM and AVPR1A may exert an effect on aggression through mechanisms involving nucleus accumbens and amygdala volumes, respectively. PMID:29666571

Over the years it has been assumed, that the greater the number of pilot flight hours, the better the development of problem-solving skills among pilots. Research suggests, however, that the problem is more complex than that. Not only one's experience is of importance - temperament, aggression and risk may also affect the decision-making process under stressful conditions. We examined 97 male pilots of passenger planes, who had flew ATRs, Boeings, Airbuses, Embraers, and Saabs. The comparative group was made up of 127 graduates of technical studies (not connected with aviation). In our study, we used the following methods: the PTS (Pavlovian Temperament Survey) Temperament Questionnaire by Strelau, the Aggression Questionnaire by Buss and Perry, and the Stimulating-Instrumental Risk Inventory (SIRI) by Zaleśkiewicz. Following the analyses we could categorize the pilots into 3 distinct groups: group 1 - strong type of nervous system with a tendency to avoid risk; group 2 - strong type of nervous system with a tendency to take risks; group 3 - the relatively weakest type of nervous system with a tendency toward aggressive behavior. Members of each group were analyzed to assess how they function in a task situation, i.e., whilst piloting a passenger plane. The study showed that individuals with high need for stimulation may - consciously or not - seek situations of excessive or unnecessary risks, and this is done in order to reach the right level of stimulation. A constellation of the following variables: temperament, risk, and aggression could be - we argue - useful in psychological examinations, and should be taken into account in training procedures for pilots.

The co-occurrence of bullying and cyberbullying in a dual society like the present calls for specific measures of intervention to be able to forestall the emergence of new problems and slow the increase and diversification of violent behavior. This study's objective was to determine whether the gender of those involved as well as the forms of aggression experienced both in presential and virtual scenarios are predictive indicators of the violent behavior of aggressive-victims. The participant sample was 1,648 adolescents aged 12 to 16 years (48.9% girls). The instrument used was a questionnaire. The results show the existence of four categories of aggressive-victims resulting from the co-occurrence of presential and cyber contexts: aggressive-victims of bullying, cyberaggressive-victims, aggressive-cybervictims, and cyberaggressive-cybervictims. Furthermore, three predictive indicators of the abusive behavior of the aggressive-victims in their different categories were identified: continuity between contexts, type of abuse suffered, and the gender of those involved. These indicators allow one to extract individual profiles of the different types of aggressive-victims, which facilitate, on one hand, the understanding of the processes of victimization and aggression that adolescents experience in both presential and cyber contexts, and, on the other, the design of programs and specific actions based on the characteristics of the adolescents and their previous experiences of victimization or cybervictimization. © The Author(s) 2014.

The aim of this study was to assess the reciprocal associations among social information processing (SIP) in dating conflicts and the perpetration of dating aggression. A first step involved the development of a measure (The Social Information Processing Questionnaire in Dating Conflicts, SIPQ-DC) to assess social information in scenarios of conflict with dating partners. A sample of 1,272 adolescents (653 girls, 619 boys; Mage = 14.74 years, SD = 1.21) completed measures of SIP and dating aggression perpetration in two different times, which were spaced 1 year apart. Confirmatory factor analyses provided support for a model with five correlated factors for the SIPQ-DC, namely, hostile attribution, anger, aggressive response access, anticipation of positive consequences for oneself, and anticipation of negative consequences for partners. Although the perpetration of dating aggression at T1 was cross-sectionally associated with all the SIP components, anger was the only component that predicted the residual increase in dating aggression behavior over time. The perpetration of dating aggression predicted a worsening of cognitive-emotional processes involved in dating conflicts. Some longitudinal paths were significant only in male adolescents. In conclusion, relationships among SIP and aggression are reciprocal. Gender differences in longitudinal paths can contribute to explaining men's higher perpetration of violence in adulthood. © The Author(s) 2014.

Objective This study investigated whether young people’s substance use and aggressive behaviors are related to their listening to music containing messages of substance use and violence. Method Data were collected using self-administered questionnaires and from a sample of community college students aged 15-25 (N = 1056; 43% male). A structural equation modeling method was used to simultaneously assess the associations between listening to various genres of music, alcohol use, illicit drug use, and aggressive behaviors, taking into account respondents’ age, gender, race/ethnicity, and level of sensation seeking. Results Listening to rap music was significantly and positively associated with alcohol use, problematic alcohol use, illicit drug use, and aggressive behaviors when all other variables were controlled. Additionally, alcohol and illicit drug use were positively associated with listening to musical genres of techno and reggae. Control variables such as sensation seeking, age, gender and race/ethnicity were significantly related to substance use and aggressive behaviors. Conclusion The findings suggest that young people’s substance use and aggressive behaviors may be related to their frequent exposure to music containing references to substance use and violence. Conversely, music listening preference may reflect some personal predispositions or lifestyle preferences. Alternatively, substance use, aggression and music preference are independent constructs, but share common “third factors.” PMID:16608146

The link between alcohol and men's aggression is well established, although growing evidence also points to individual and learned social factors. The aim of the present study was to investigate the relationships between male alcohol-related aggression (MARA) among young Australian men and heavy episodic drinking, trait aggression, masculinity, concerns about social honour and expected positive consequences of MARA. The total sample comprised 170 men aged 18-25 years who completed an online questionnaire exploring beliefs and attitudes towards MARA. Those who reported heavy episodic drinking were more likely to be involved in an incident of MARA. In addition, those who were involved in MARA had higher levels of trait aggression, concern for social honour and expected positive consequences of aggression in bars than did those without such involvement. The relationship between socially constructed masculinity factors (a combined variable reflecting masculinity, social honour and expected positive consequences) and MARA was mediated by heavy episodic drinking. Social honour accounted for almost all of the predictive power of masculinity factors. Heavy episodic drinking and trait aggression remained significant predictors of MARA in a multivariate model. The findings from the current study may assist in developing preventative techniques for young men which target masculinity concerns and the consequences of participating in MARA. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Oxytocin (OT) not only modulates positive social interactions but also affects negative ones. Several studies have established a link between OT and aggression. However, they also resulted in an inconsistent picture and showed methodological issues. The current studies aimed to address these lacks and test the hypothesis that OT increases provocation-induced aggression in people low in anxiety. Therefore, two studies with 56 males (Study 1) as well as 40 females and 24 males (Study 2) were conducted. After responding to a trait anxiety questionnaire, participants self-administered OT or a placebo. Thereafter, provocation was manipulated by rejecting vs. accepting (Study 1) or insulting vs. accepting (Study 2) the participants by real human counterparts. Aggressive behavior was quantified by measuring how much hot sauce (Study 1) or unpleasant blasts of white noise (Study 2) participants delivered to their opponents, using two classic aggression paradigms. Both studies provided evidence that OT promotes aggression in response to provocation in low anxiety people which was not the case with no provocation or in high anxiety people. These findings confirm the idea that OT can be involved in the creation of aggressive behavior when accounting for situational and dispositional features. Copyright © 2018 Elsevier Ltd.

This study investigated whether young people's substance use and aggressive behaviors are related to their listening to music containing messages of substance use and violence. Using self-administered questionnaires, data were collected from a sample of community-college students, ages 15-25 years (N=1056; 57% female). A structural equation model (maximum likelihood method) was used to simultaneously assess the associations between listening to various genres of music and students' alcohol use, illicit-drug use, and aggressive behaviors. Respondents' age, gender, race/ethnicity, and level of sensation seeking were included in the analyses as control variables. Listening to rap music was significantly and positively associated with alcohol use, problematic alcohol use, illicit-drug use, and aggressive behaviors when all other variables were controlled. In addition, alcohol and illicit-drug use were positively associated with listening to musical genres of techno and reggae. Control variables (e.g., sensation seeking, age, gender and race/ethnicity) were significantly related to substance use and aggressive behaviors. The findings suggest that young people's substance use and aggressive behaviors may be related to their frequent exposure to music containing references to substance use and violence. Music listening preference, conversely, may reflect some personal predispositions or lifestyle preferences. There is also the possibility that substance use, aggression, and music preference are independent constructs that share common "third factors".

One of the major challenges for research in the field of human aggression is the need to define the role of personality and trait-like dimensions, such as impulsivity and aggressiveness, in predisposing to violent behavior. 1) To determine whether trait- aggressiveness and impulsivity may be associated with socio-demographic, clinical and crime history variables in a sample of male prisoners; 2) to detect any association of those traits with measures of early traumatic experiences and current resilience traits. A sample of male prisoners (n = 1356) underwent the Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA) and the Barratt Impulsivity Scale (BIS). Axis I psychiatric disorders were also assessed. Early traumatic experiences and psychological resilience were detected respectively by the Childhood Trauma Questionnaire (CTQ) and the Connor-Davidson Resilience Scale (CD-RISC). Two non-linear logistic regression models were performed to test for the best predictors of trait-aggressiveness and impulsivity. Subjects with a history of substance use disorders and self-mutilation reported both higher BGLHA and BIS scores. Axis I disorders and suicide attempts were associated with aggressiveness, but not to impulsivity. A consistent correlation was found between BGLHA scores and early traumatic experiences. Resilience was positively correlated to impulsivity but not to aggressiveness scores. Our results support the view that aggressiveness and impulsivity are two different, albeit related trait-like dimensions of personality, having a different relationship with resilience, and, inferentially, a different impact over the development of psychiatric disorders.

Several studies show certain co-occurrence of the traditional bullying and the cyberbullying. However, the results about relation and homogeneity among the roles of each of them are not unanimous. The present study intends to advance in the knowledge about the above-mentioned co-occurrence by exploring the dimensions of victimization and traditional aggression and cyber-victimization and cyber-aggression and by identifying its eventual directionality. A short-term longitudinal design was developed. The sample was formed by 274 adolescents, aging 12 to 18 years-old, belonging to 2 schools of Andalusia (South of Spain). In order to value the impact of bullying and cyberbullying the European Cyberbullying Intervention Project Questionnaire (ECIPQ) and the European Bullying Intervention Project Questionnaire (EBIPQ) were used. The results show important simultaneity among both phenomena and suggest that although in cyberbullying -cyber-victimization and cyber-aggression- may be predicted because of previous involvement of the subject in traditional bullying, on the contrary it does not happen. In addition, previous victimization is a risk factor for traditional bullying and for cyberbullying. Results are discussed in relation to the process and socio-group dynamics arising from the bullying and cyberbullying phenomena, and in terms of their prevention.

Aggression and Violence against primary care physicians is reportedly common in Pakistan but there is no any documented study to-date on this burning issue. A formed written questionnaire was distributed among 769 primary care physicians aged 31 ± 7.68 years. Apart from the demographic data, the questionnaire included questions regarding the level of safety that primary care physicians felt during their work setups and on-call duties, along with the experience of aggression against them by the perpetrators & the support provided by the hospital management in such cases. Response rate was 68% i.e. 524 physicians agreed to participate in the study. It was found that majority (85%) of the physicians has faced mild events, 62% have faced moderate events and roughly 38% were subjected to severe violence. Some physicians revealed more than one form of aggression being faced by them in 12 months preceding months which makes the collective percentage greater than 100%. Verbal abuse is the most frequent type of mistreatment faced by the doctors from the patients or their attendants. A considerable number of physicians participated have faced mild violence in which verbal abuse was commonest; followed by moderate and severe events.

In the present study, the correlation was examined between pre-morbid personality traits and the occurrence of aggressive behaviour in residents of a psychogeriatric nursing home. The participants in the study were the close relatives of 39 residents of a psychogeriatric nursing home. These residents were selected on the basis of two subscales of the BOP assessment scale for elderly patients: Aggressive and annoying behaviour, and mental disability. Residents were divided into two groups: one group did not display aggressive behaviour, the other group displayed a great deal of such behaviour. The groups were comparable with regard to the degree of mental disability. To ascertain pre-morbid personality traits, use was made of the hetero-anamnestic personality questionnaire (HAP) and the Quick Big Five (QBF). We found no significant differences in any of the premorbid personality traits between the two groups. We could not confirm the conclusion of other authors that emotional lability (neuroticism) is a personality trait which makes people susceptible to developing aggressive behaviour. In conclusion, our study did not confirm the hypothesis that pre-morbid personality traits are useful to explain the occurrence of aggressive behaviour in residents of a psychogeriatric nursing home.

The effect of online violent video games on levels of aggression.

In recent years the video game industry has surpassed both the music and video industries in sales. Currently violent video games are among the most popular video games played by consumers, most specifically First-Person Shooters (FPS). Technological advancements in game play experience including the ability to play online has accounted for this increase in popularity. Previous research, utilising the General Aggression Model (GAM), has identified that violent video games increase levels of aggression. Little is known, however, as to the effect of playing a violent video game online. Participants (N = 101) were randomly assigned to one of four experimental conditions; neutral video game--offline, neutral video game--online, violent video game--offline and violent video game--online. Following this they completed questionnaires to assess their attitudes towards the game and engaged in a chilli sauce paradigm to measure behavioural aggression. The results identified that participants who played a violent video game exhibited more aggression than those who played a neutral video game. Furthermore, this main effect was not particularly pronounced when the game was played online. These findings suggest that both playing violent video games online and offline compared to playing neutral video games increases aggression.

The purpose of this study was to examine the following hypothesis: (i) Self-esteem and aggressiveness, adverse childhood experiences (ACE), and a depressive tendency interact with each other. (ii) The subjects show a strong depressive tendency, and each of the other factors exerts a main effect on, and interacts with, the depressive tendency. The subjects were 91 juveniles (all female) admitted to a female juvenile correctional facility between November 2005 and December 2006. They were aged 15-19 years, with a mean age of 17.0 (SD = 1.18) years. Self-esteem scale, aggression scale, ACE questionnaire, and depression scale were conducted. Significant main effects (R(2) = 0.50, P < 0.001) on the depression score were observed in self-esteem (beta = -0.41, P < 0.001) and aggression (beta = 0.21, P < 0.05). Self-esteem, aggression, ACE, and depression were found to be interrelated. Low self-esteem was also shown to exert marked effects on various factors. About half of the inmates of the facility were depressed, and the main effects of self-esteem, aggression, and the ACE score were shown to influence the depression score.

This prospective longitudinal study focused on self-regulatory, social-cognitive, and parenting precursors of individual differences in children's peer-directed aggression at early school age. Participants were 199 3-year-old boys and girls who were reassessed following the transition to kindergarten (5.5-6 years). Peer aggression was assessed in preschool and school settings using naturalistic observations and teacher reports. Children's self-regulation abilities and theory of mind understanding were assessed during a laboratory visit, and parenting risk (corporal punishment and low warmth/responsiveness) was assessed using interview-based and questionnaire measures. Individual differences in children's peer aggression were moderately stable across the preschool to school transition. Preschool-age children who manifested high levels of aggressive peer interactions also showed lower levels of self-regulation and theory of mind understanding, and experienced higher levels of adverse parenting than others. Our main finding was that early corporal punishment was associated with increased levels of peer aggression across the transition from preschool to school, as was the interaction between low maternal emotional support and children's early delays in theory of mind understanding. These data highlight the need for family-directed preventive efforts during the early preschool years.

Behavioral profiles of feline breeds in Japan.

To clarify the behavioral profiles of 9 feline purebreds, 2 Persian subbreeds and the Japanese domestic cat, a questionnaire survey was distributed to 67 small-animal veterinarians. We found significant differences among breeds in all behavioral traits examined except for "inappropriate elimination". In addition, sexual differences were observed in certain behaviors, including "aggression toward cats", "general activity", "novelty-seeking", and "excitability". These behaviors were more common in males than females, whereas "nervousness" and "inappropriate elimination" were rated higher in females. When all breeds were categorized into four groups on the basis of a cluster analysis using the scores of two behavioral trait factors called "aggressiveness/sensitivity" and "vivaciousness", the group including Abyssinian, Russian Blue, Somali, Siamese, and Chinchilla breeds showed high aggressiveness/sensitivity and low vivaciousness. In contrast, the group including the American Shorthair and Japanese domestic cat displayed low aggressiveness/sensitivity and high vivaciousness, and the Himalayan and Persian group showed mild aggressiveness/sensitivity and very low vivaciousness. Finally, the group containing Maine Coon, Ragdoll, and Scottish Fold breeds displayed very low aggressiveness/sensitivity and low vivaciousness. The present results demonstrate that some feline behavioral traits vary by breed and/or sex.

Aggressive behavior in schizophrenia is associated with the low enzyme activity COMT polymorphism: a replication study.

We have previously reported that increased aggressive behavior in schizophrenic patients may be associated with a polymorphism at codon 158 of the catechol O-methyltransferase (COMT) gene that encodes a low enzyme activity variant. The finding has been replicated by one group, but not others. The discordant findings could be due to statistical errors or methodological issues in the assessment of aggressive/violent behavior. Consequently, additional studies are needed. Patients with schizophrenia (SZ) were assessed for violent behavior using the Lifetime History of Aggression (LHA) scale, an 11-item questionnaire that includes Aggression, Self-Directed Aggression, and Consequences/Antisocial Behavior subscales. DNA was genotyped for the COMT 158 polymorphism, as well as a functional polymorphism in the monoamine oxidase A (MAOA) gene promoter. Similar to our previously reported findings, a statistically significant association was found between aggressive behavior in SZ and the COMT 158 polymorphism; mean LHA scores were higher in subjects homozygous for 158Met, the low enzyme activity COMT variant (F(2,105) = 5.616, P = 0.005). Analysis of the major LHA subscales revealed that the association with 158Met was due to high scores on the Aggression, and Self-Directed Aggression subscales, but not the Consequences/Antisocial Behavior subscale. No significant association was detected for the MAOA gene alone. Our findings provide further support that COMT is a modifying gene that plays a role in determining interindividual variability in the proclivity for outward and self-directed aggressive behavior found in some schizophrenic patients.

Parental acceptance, postpartum depression, and maternal sensitivity: mediating and moderating processes.

Crockenberg, Susan C; Leerkes, Esther M

2003-03-01

Mothers (n = 92), fathers (n = 84), and their infants (60% male) participated in a longitudinal study of postpartum depression and maternal sensitivity. Mothers completed questionnaire measures of remembered parental acceptance, depressive symptoms, and infant distress to novelty and limits. Mothers and partners reported on marital aggression and avoidance. Maternal sensitivity was observed in the laboratory at 6 months. Characteristics of mothers, partners, and infants combined to predict postpartum depression and maternal sensitivity. Remembered parental rejection predicted postpartum depressive symptoms with prenatal depression controlled; self-esteem mediated this effect. Paternal acceptance buffered against postpartum depression when infants were highly reactive and when partners were aggressive. Paternal acceptance reduced the impact of postpartum depression on maternal sensitivity; having an aggressive marital partner exacerbated the effect.

Development of the Observation Scale for Aggressive Behavior (OSAB) for Dutch forensic psychiatric inpatients with an antisocial personality disorder.

The Observation Scale for Aggressive Behavior (OSAB) has been developed to evaluate inpatient treatment programs designed to reduce aggressive behavior in Dutch forensic psychiatric patients with an antisocial personality disorder, who are "placed at the disposal of the government". The scale should have the sensitivity to measure changes in the possible determinants of aggressive behavior, such as limited control of displayed negative emotions (irritation, anger or rage) and a general deficiency of social skills. In developing the OSAB 40 items were selected from a pool of 82 and distributed among the following a priori scales: Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent (to aggressive behavior), Sanction (for aggressive behavior) and Social behavior. The internal consistency of these subscales was good, the inter-rater reliability was moderate to good, and the test-retest reliability over a two to three week period was moderate to good. The correlation between the subscales Irritation/anger, Anxiety/gloominess, Aggressive behavior, Antecedent, Sanction was substantial and significant, but the anticipated negative correlation between these subscales and the Social behavior subscale could not be shown. Relationships between the corresponding subscales of the OSAB and the FIOS, used to calculate concurrent validity, yielded relatively high correlations. The validity of the various OSAB subscales could be further supported by significant correlations with the PCL-R and by significant but weak correlations with corresponding subscales of the self-report questionnaires. The Observation Scale for Aggressive Behavior (OSAB) seems to measure aggressive behavior in Dutch forensic psychiatric inpatients with an antisocial personality disorder reliably and validly. Contrary to expectations, a negative relationship was not found between aggressive and social behavior in either the OSAB or FIOS, which were used for calculating concurrent validity.

Aggressive disorders are moderately heritable; therefore, identification of genetic influences is important. The X-linked MAOA gene, encoding the MAOA enzyme, has a functional 30bp repeat polymorphism in the promoter region (MAOA-LPR) that has been shown to influence aggression. Childhood trauma is a known risk factor for numerous psychopathologies in adulthood including aggressive behaviors. We investigated the interactive effect of MAOA-LPR genotype and a history of childhood trauma in predicting aggressive behaviors in a prisoner population. A total of 692 male prisoners were genotyped for MAOA-LPR with genotypes grouped into high and low transcriptional activity. Participant evaluations included measures of aggression (BGHA), hostility (Buss Durkee Hostility Inventory), impulsivity (Barratt Impulsiveness Scale), violence directed towards self and others, and childhood trauma (Childhood Trauma Questionnaire (CTQ)). MAOA-LPR interacted with CTQ physical neglect (PN), the most common (47%) form of childhood trauma in this sample, to predict BGHA aggression (P=0.002). Within the group not exposed to PN, carriers of the MAOA-LPR high activity variant were more aggressive: (t(R) =2.47, p<0.014). We observed a crossover effect in that the increase in aggression scores with PN was greater in low activity individuals (t(R) =5.55, p <0.0001) than in high activity individuals (t(R) =4.18, p <0.0001). These findings suggest that childhood trauma and the functional MAOA-LPR polymorphism may interact to specifically increase risk for over aggressive behavior but not impulsivity or hostility. The MAOA-LPR low activity variant may be protective against the development of aggressive behavior under low stress conditions, at least in this prisoner population. PMID:24805005

[Motives and interpersonal functions of aggression].

PubMed

Ohbuchi, K

1987-06-01

In this review, the author theoretically and empirically examined motives and interpersonal functions of aggression. A factor-analysis of Averill's questionnaire items on anger revealed that motives involved in aggressive responses were clustered into two groups: the hostile and the instrumental. It was also clarified that an individual is likely to engage in aggression particularly when some hostile motives are evoked. Concerning the interpersonal functions, the author proposed that aggression might serve four principal goals. (1) Aggression can be generated as an avoidance response to an aversive stimulus, such as frustration, annoyance, or pain, and so on. It depends on the severity of the stimulus. It was however emphasized that aggression is also mediated by social cognition, such as an attribution of intent to a harm-doer. (2) Aggression can be used as a means of coercing the other person into doing something. An individual is likely to use such a power strategy if he/she is lacking in self-confidence or a perspective for influencing the target person by more peaceful strategies. (3) Aggression can be interpreted as a punishment when it is directed toward a transgressor. In this case, aggression is motivated by restoration of a social justice, and thus its intensity is determined by the perceived moral responsibility of the transgressor. Further, it was indicated that aggression is intensified if it is justified as a sanctional conduct against the immoral. (4) Aggression can be also evoked when an individual's social identity is threatened. It was suggested that impression management motives are involved in aggression by an unexpected finding that the presence of audience or the identifiability rather facilitated retaliative aggression. The aggression-inhibition effect of apology was also explained in terms of impression management. In conclusion, it was presented that aggression is a behavioral strategy as an attempt to resolve interpersonal conflicts including physical or psychological annoyance, the other person's disobedience, perceived injustice, and a threat to one's social identity. Whether one's aggression is performed or not depends on a number of intra- and inter-personal determinants, particularly on social cognitive processes such as attribution, inference, prediction and other judgements.

Gonadectomy is widely used to treat and prevent behavior problems including the aggressive behavior of dogs. The aim of this study was to determine whether aggressive behavior toward familiar people, strangers, or other dogs was significantly different in dogs gonadectomized at various ages vs. intact dogs using the Canine Behavioral Assessment Research Questionnaire (C-BARQ) with multivariate analysis. Of 15,370 initial surveys, those for dogs reported to have been gonadectomized at less than 6 weeks of age or to correct a behavior problem, and those with incomplete answers to questions regarding independent or dependent variables were excluded, leaving 13,795 for the analysis of aggressive behavior toward familiar people: 13,498 for aggressive behavior toward strangers and 13,237 for aggressive behavior toward dogs. Aggressive behavior was defined (a) using mean scores for all questions on the C-BARQ for aggressive behavior (range 0-4) and (b) comparing dogs with no aggressive behavior (all questions answered 0) to dogs with moderate or severe aggression (at least one score of 2, 3, or 4). Data for intact dogs were compared with those for dogs gonadectomized at 6 months or less, 7-12 months, 11-18 months, and >18 months. Neither gonadectomy nor age at gonadectomy showed an association with aggression toward familiar people or dogs. However, there was a low but significant increase in the odds of moderate or severe aggression toward strangers for all gonadectomized dogs compared with intact dogs, but this effect was driven entirely by data for dogs gonadectomized at 7-12 months of age, which were 26% more likely to demonstrate aggression toward strangers. This large, comprehensive study of the relationships between gonadectomy and aggressive behavior in dogs demonstrates that when the many factors affecting aggressive behavior are considered, there is no evidence that gonadectomy at any age alters aggressive behavior toward familiar people or dogs, and there is only a minimal increase in aggression toward strangers. Given the increasing evidence of significant negative health effects of gonadectomy, there is an urgent need to systematically examine other means of preventing unwanted procreation, such as vasectomy and hysterectomy.

The effects of Aggression Replacement Training (ART) were explored in a group of Dutch violent young men aged 16 to 21 years, who were obliged by the court to follow a treatment program in a forensic psychiatric outpatient clinic. To evaluate the training, patients completed a set of self-report questionnaires at three moments in time: at intake/before a waiting period, after the waiting period/before the training, and after the training. During the waiting period, the patients did not change on most measures, although they displayed a significant increase in anger. The patients who completed the therapy scored significantly lower on psychopathy than the patients who dropped out. The training produced significant decreases in physical aggression and social anxiety and showed trends toward a decline in self-reported hostility, general aggression, and anger. After the training, the patients scored comparably with a reference group on measures of hostility and aggressive behavior. Altogether, these results provide tentative support for the efficacy of the ART for violent young men referred to forensic psychiatric outpatient settings. © The Author(s) 2014.

Background In Iran, traffic accidents and deaths from traffic accidents are among the highest in the world, and generally driver behavior rather than either technical failures or environmental conditions are responsible for traffic accidents. In the present study, we explored the extent to which aggressive traits, health status, and sociodemographic variables explain driving behavior among Iranian male traffic offenders. Method A total of 443 male driving offenders (mean age: M =31.40 years, standard deviation =9.56) from Kermanshah (Iran) took part in the study. Participants completed a questionnaire booklet covering sociodemographic variables, traits of aggression, health status, and driving behavior. Results Poor health status, such as symptoms of depression, anxiety, insomnia, and social dysfunction, and also higher levels of trait aggression explained poor driving behavior. Multiple regressions indicated that poor health status, but not aggression, independently predicted poor driving behavior. Conclusion Results suggest that health status concerns are associated with poor driving behavior. Prevention and intervention might therefore focus on drivers reporting poor mental health status.

Mental health nurses are exposed to patient aggression, and required to manage and de-escalate aggressive incidents; coercive measures such as restraint and seclusion should only be used as a last resort. An improved understanding of links between nurses' exposure to aggression, attitudes to, and actual involvement in, coercive measures, and their emotions (anger, guilt, fear, fatigue, sadness), could inform preparation and education for prevention and management of violence. To identify relationships between mental health nurses' exposure to patient aggression, their emotions, their attitudes towards coercive containment measures, and their involvement in incidents involving seclusion and restraint. Cross-sectional, correlational, observational study. Low and medium secure wards for men and women with mental disorder in three secure mental health hospitals in England. N=Sixty eight mental health nurses who were designated keyworkers for patients enrolled into a related study. Participants completed a questionnaire battery comprising measures of their exposure to various types of aggression, their attitudes towards seclusion and restraint, and their emotions. Information about their involvement in restraint and/or restraint plus seclusion incidents was gathered for the three-month period pre- and post- their participation. Linear and logistic regression analyses were performed to test study hypotheses. Nurses who reported greater exposure to a related set of aggressive behaviours, mostly verbal in nature, which seemed personally derogatory, targeted, or humiliating, also reported higher levels of anger-related provocation. Exposure to mild and severe physical aggression was unrelated to nurses' emotions. Nurses' reported anger was significantly positively correlated with their endorsement of restraint as a management technique, but not with their actual involvement in restraint episodes. Significant differences in scores related to anger and fatigue, and to fatigue and guilt, between those involved/not involved in physical restraint and in physical restraint plus seclusion respectively were detected. In regression analyses, models comprising significant variables, but not the variables themselves, predicted involvement/non-involvement in coercive measures. Verbal aggression which appears targeted, demeaning or humiliating is associated with higher experienced anger provocation. Nurses may benefit from interventions which aim to improve their skills and coping strategies for dealing with this specific aggressive behaviour. Nurse-reported anger predicted approval of coercive violence management interventions; this may have implications for staff deployment and support. However, anger did not predict actual involvement in such incidents. Possible explanations are that nurses experiencing anger are sufficiently self-aware to avoid involvement or that teams are successful in supporting colleagues who they perceive to be 'at risk'. Future research priorities are considered. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objective The primary aim of the present investigation was to directly examine a theoretically-based, self-awareness intervention manipulation for at-risk men’s alcohol-related aggression toward women. This study was developed in response to a call in the literature for research to (1) empirically investigate specific intervention techniques that reduce aggression, and (2) identify in whom such interventions will have the greatest impact. Method A community sample (77% African-American) of 94 heavy drinking males age 21 years and older (M = 35.61) completed a battery of questionnaires that assessed alcohol consumption and perpetration of aggression toward women during the past year as well as dispositional masculine gender role stress. Participants were randomly assigned to an intervention manipulation designed to focus attention onto inhibitory, self-awareness cues or a control group. Following beverage consumption, participants were provoked with a gender-relevant provocation from a female confederate and participants’ physical aggression was measured using a shock-based aggression task. Results Men who received the intervention manipulation, relative to control, enacted significantly less alcohol-related physical aggression toward the female confederate. This finding held for men who reported lower, but not higher, levels of masculine gender role stress. Conclusions Findings support the development of interventions that aim to redirect intoxicated men’s attention toward stimuli that is non-aggressive, non-provocative, and/or prohibitive of aggressive behavior. However, caution is warranted that en masse dissemination of such interventions may not impact the most at-risk men for alcohol-related violence toward women. PMID:27176660

Competitive examinations, particularly in mathematics, have made emotional stress a major problem for preuniversity students, emotions like aggression toward fellow students and teachers increase. Mindfulness is a quality that reduces both emotional stress and aggression, so increasing mindfulness should be helpful. To study the effects of Yoga Pranayama (YP) and Vedic Mathematics (VM) on mindfulness, aggression, and emotion regulation. Participants were 12 th graders attending a preuniversity college in Chikkamagaluru, India, of both genders. Exclusion criteria included major psychological problems. Three classes were arbitrarily assigned to one of three interventions, which consisted of 15 days each of 30 min daily instruction in YP, Group 1, VM, Group 2, or 30 min ordinary class work, Group 3, the control group. Assessments were made using the Mindfulness Attention Awareness Scale, the Nonphysical Aggression Scale from Pittsburgh Youth Study, and the Emotion Regulation Questionnaire. SPSS 19.0. Mindfulness, aggression, and negative emotional regulation changed significantly for the YP group, while mindfulness alone improved significantly for the VM group. No group changed on positive emotion regulation. Controls apparently improved on aggression. An interesting post hoc correlation analysis is also reported, among other things directly linking increased mindfulness to decreased aggression. The study showed positive effects of traditional methods of decreasing emotional pressure on students facing preuniversity mathematics examinations. Increasing mindfulness is considered a way of increasing emotion regulation, so the failure of this study to provide evidence for that is of interest.

Background In Iran, traffic accidents and deaths from traffic accidents are among the highest in the world, and generally, driver behavior rather than technical failures or environmental conditions are responsible for traffic accidents. In a previous study, we showed that among young Iranian male traffic offenders, poor mental health status, along with aggression, predicted poor driving behavior. The aims of the present study were twofold, to determine whether this pattern could be replicated among non-traffic offenders, and to compare the mental health status, aggression, and driving behavior of male traffic offenders and non-offenders. Methods A total of 850 male drivers (mean age =34.25 years, standard deviation =10.44) from Kermanshah (Iran) took part in the study. Of these, 443 were offenders (52.1%) and 407 (47.9%) were non-offenders with lowest driving penalty scores applying for attaining an international driving license. Participants completed a questionnaire booklet covering socio-demographic variables, traits of aggression, health status, and driving behavior. Results Compared to non-offenders, offenders reported higher aggression, poorer mental health status, and worse driving behavior. Among non-offenders, multiple regression indicated that poor health status, but not aggression, independently predicted poor driving behavior. Conclusion Compared to non-offenders, offenders reported higher aggression, poorer health status and driving behavior. Further, the predictive power of poorer mental health status, but not aggression, for driving behavior was replicated for male non-offenders. PMID:26300646

The genetic deletion of monoamine oxidase A (MAO A, an enzyme which breaks down the monoamine neurotransmitters norepinephrine, serotonin and dopamine) produces aggressive phenotypes across species. Therefore, a common polymorphism in the MAO A gene (MAOA, MIM 309850, referred to as high or low based on transcription in non-neuronal cells) has been investigated in a number of externalizing behavioral and clinical phenotypes. These studies provide evidence linking the low MAOA genotype and violent behavior but only through interaction with severe environmental stressors during childhood. Here, we hypothesized that in healthy adult males the gene product of MAO A in the brain, rather than the gene per se, would be associated with regulating the concentration of brain amines involved in trait aggression. Brain MAO A activity was measured in-vivo in healthy non-smoking men with positron emission tomography using a radioligand specific for MAO A (clorgyline labeled with carbon 11). Trait aggression was measured with the Multidimensional Personality Questionnaire (MPQ). Here we report for the first time that brain MAO A correlates inversely with the MPQ trait measure of aggression (but not with other personality traits) such that the lower the MAO A activity in cortical and subcortical brain regions the higher the self-reported aggression (in both MAOA genotype groups) contributing to more than a third of the variability. Since trait aggression is a measure used to predict antisocial behavior, these results underscore the relevance of MAO A as a neurochemical substrate of aberrant aggression. PMID:18463263

[Impulsivity - aggression - depression: study of adolescents' problem behavior in light of their personality traits].

Impulsivity is a personality trait that may determine our everyday living, quality of life, decisions. Impulsivity in particular has a great significance during adolescence as a part of the adolescent neuroanatomical and neuropsychiatric developmental processes. The main goal of the present study was to examine correlations among depressive symptomatology, types of aggressive behaviors (verbal, physical, psychic), impulsivity and other personality traits (risk-taking, empathy and self-efficacy) in adolescents. Data collection was going on in Debrecen during the first semester of the year 2012 using classes from three high schools (N = 413), 237 (57,4%) boys and 176 (42,6%) girls. The self-administered questionnaire contained items on mental health and personality traits beyond sociodemographics. After descriptive statistics, correlation and multiple linear regression analyses were applied to detect correlations. Girls reported more depressive symptoms and their level of empathy was also higher. In terms of aggression, significant gender difference was detected only in case of physical aggression with a surplus of boys. Based on multiple regression analyses, we may conclude that impulsivity acted as a risk factor both for mean levels of depressive symptomatology and aggression scales. Besides, lack of empathy proved to be related to physical aggression. In both sexes, self-efficacy was positively associated with verbal and physical aggression. Among girls, self-efficacy was a negative predictor of psychic aggression, that is, it seems to act as a protective factor. In summary, we may conclude that there are strong correlations among depressive symptomatology, aggressive behaviors and impulsivity, and this association may be colored by further personality traits, such as risk-taking, empathy, and self-efficacy. There is a need for learning some basic effective techniques for aggression management and self control as early as adolescence.

Reducing Schoolchildren With Reactive Aggression Through Child, Parent, and Conjoint Parent-Child Group Interventions: A Longitudinal Outcome Effectiveness Study.

PubMed

Fung, Annis Lai Chu

2017-10-10

This study was the first to evaluate the effectiveness of three different group interventions to reduce children's reactive aggression based on the social information processing (SIP) model. In the first stage of screening, 3,734 children of Grades 4-6 completed the Reactive-Proactive Aggression Questionnaire (RPQ) to assess their reactive and proactive aggression. Respondents with a total score of z ≥ 1 on the RPQ were shortlisted for the second stage of screening by qualitative interview. Interviews with 475 children were conducted to select those who showed reactive aggression featuring a hostile attributional bias. Finally, 126 children (97 males and 29 females) aged 8 to 14 (M = 9.71, SD = 1.23) were selected and randomly assigned to one of the three groups: a child group, a parent group, and a parent-child group. A significant Time × Intervention effect was found for general and reactive aggression. The parent-child group and child group showed a significant drop in general aggression and reactive aggression from posttest to 6-month follow-up, after controlling for baseline scores, sex, and age. However, the parent group showed no treatment effect: reactive aggression scores were significantly higher than those in the child group at 6-month follow-up. This study has provided strong evidence that children with reactive aggression need direct and specific treatment to reconstruct the steps of the SIP involving the selection and interpretation of cues. The intervention could help to prevent severe violent crimes at the later stage of a reactive aggressor. © 2017 Family Process Institute.

Physical and psychological aggression in dating relationships of Spanish adolescents: motives and consequences.

The purpose of the study was to examine three aspects of romantic relationships of Spanish adolescents: the prevalence of verbal-emotional and physical aggressive behaviors, correlates of dating violence perpetration (both verbal-emotional and physical aggression), and consequences of violence for victims' well-being. A convenience sample of 567 participants (15-19 years old) who voluntarily completed anonymous, self-report questionnaires was used. All were students from 5 public high schools in Salamanca, Spain. Females reported having perpetrated significantly more aggressive acts in their intimate relationships than males did, although the magnitude of differences between both groups was small; in contrast, no sex differences were noted in the frequency of aggressions suffered by adolescents. A strong relationship was observed between the perpetration and victimization of both verbal-emotional and physical aggression across genders. A strong link was observed between jealousy and aggression perpetration (both verbal-emotional and physical). Finally, verbal-emotional aggression represented the most common form of aggressive behavior used at these ages, and relationship deterioration was the most frequent consequence of arguments. These results demonstrate that the use of abusive behaviors in adolescent dating relationships is prevalent in Spain. Sex differences were evident in the perpetration of aggression, as well as some of the motivations for, and the effects of, dating violence. The present study underlines the need for early intervention programs aimed at decreasing any tolerance for the use of violence in dating relationships of Spanish adolescents. Such programs should include both victimization-based and perpetration-based activities, since the evidence on the relatively mutual nature of dating violence in adolescence points in this direction.

Individual differences in aggressive behavior emerge in early childhood and predict persisting behavioral problems and disorders. Studies of antisocial and severe aggression in adulthood indicate substantial underlying biology. However, little attention has been given to genome-wide approaches of aggressive behavior in children. We analyzed data from nine population-based studies and assessed aggressive behavior using well-validated parent-reported questionnaires. This is the largest sample exploring children's aggressive behavior to date (N = 18,988), with measures in two developmental stages (N = 15,668 early childhood and N = 16,311 middle childhood/early adolescence). First, we estimated the additive genetic variance of children's aggressive behavior based on genome-wide SNP information, using genome-wide complex trait analysis (GCTA). Second, genetic associations within each study were assessed using a quasi-Poisson regression approach, capturing the highly right-skewed distribution of aggressive behavior. Third, we performed meta-analyses of genome-wide associations for both the total age-mixed sample and the two developmental stages. Finally, we performed a gene-based test using the summary statistics of the total sample. GCTA quantified variance tagged by common SNPs (10-54%). The meta-analysis of the total sample identified one region in chromosome 2 (2p12) at near genome-wide significance (top SNP rs11126630, P = 5.30 × 10(-8) ). The separate meta-analyses of the two developmental stages revealed suggestive evidence of association at the same locus. The gene-based analysis indicated association of variation within AVPR1A with aggressive behavior. We conclude that common variants at 2p12 show suggestive evidence for association with childhood aggression. Replication of these initial findings is needed, and further studies should clarify its biological meaning. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Previous research has demonstrated an association between aggressive challenging behaviour (CB) and reductions in work-related well-being for intellectual disability (ID) support staff. Much of this research has used subjective measures of CB. To examine whether exposure to aggressive CB is associated with reduced work-related well-being in staff working in ID residential settings across the UK. A cross-sectional analysis was undertaken as part of a randomised trial; 186 staff from 100 settings completed questionnaires on their CB self-efficacy, empathy, positive work motivation, and burnout. Objective measures of aggressive CB in the preceding 16 weeks were collected from each setting. There was little association between staff exposure to aggressive CB and work-related well-being. Clustering effects were found for emotional exhaustion and positive work motivation, suggesting these variables are more likely to be influenced by the environment in which staff work. The level of clustering may be key to understanding how to support staff working in ID residential settings, and should be explored further. Longitudinal data, and studies including a comparison of staff working in ID services without aggressive CB exposure are needed to fully understand any association between aggressive CB and staff well-being.

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. 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. 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. 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.

Aggressive disorders are moderately heritable; therefore, identification of genetic influences is important. The X-linked MAOA gene, encoding the MAOA enzyme, has a functional 30 bp repeat polymorphism in the promoter region (MAOA-LPR) that has been shown to influence aggression. Childhood trauma is a known risk factor for numerous psychopathologies in adulthood including aggressive behaviors. We investigated the interactive effect of MAOA-LPR genotype and a history of childhood trauma in predicting aggressive behaviors in a prisoner population. A total of 692 male prisoners were genotyped for MAOA-LPR with genotypes grouped into high and low transcriptional activity. Participant evaluations included measures of aggression (Brown-Goodwin Lifetime History of Aggression, BGHA), hostility (Buss-Durkee Hostility Inventory), impulsivity (Barratt Impulsiveness Scale), violence directed toward self and others, and childhood trauma [Childhood Trauma Questionnaire (CTQ)]. MAOA-LPR interacted with CTQ physical neglect (PN), the most common (47%) form of childhood trauma in this sample, to predict BGHA aggression (P = 0.002). Within the group not exposed to PN, carriers of the MAOA-LPR high-activity variant were more aggressive: (tR = 2.47, P < 0.014). We observed a crossover effect in that the increase in aggression scores with PN was greater in low-activity individuals (tR = 5.55, P < 0.0001) than in high-activity individuals (tR = 4.18, P < 0.0001). These findings suggest that childhood trauma and the functional MAOA-LPR polymorphism may interact to specifically increase risk for over aggressive behavior but not impulsivity or hostility. The MAOA-LPR low-activity variant may be protective against the development of aggressive behavior under low stress conditions, at least in this prisoner population. Published 2014.

The present study compared people with depressive symptoms and people without depressive symptoms with reference to their coping styles, level of aggression and interpersonal conflicts. A purposive sample of 128 people (64 depressed and 64 normal controls)was selected from four different teaching hospitals of Lahore. Both the groups were matched on four demographic levels i.e. age, gender, education and monthly income. Symptom Checklist-R was used to screen out depressed and non-depressed people. The Brief COPE, the Aggression Questionnaire and the Bergen Social Relationship Scale were used to assess coping styles, aggression and interpersonal conflicts respectively. The Independent t-test was used to compare the groups. Binary logistic Regression was also carried out to predict the role of research variables in causing depression. The results showed that level of aggression and interpersonal conflict was significantly more in people with depressive symptoms as compared to control group. On the other hand control group was using more adaptive coping styles than people with depressive symptoms but no difference was found in the use of maladaptive coping styles. The present findings revealed that coping styles, aggression and interpersonal conflicts play important role in depression. Therefore, these dimensions must be considered while dealing with the depressive patients. Implications for preventive work are also discussed in the light of previous researches.

Acts of aggression by patients or clients are a part of the average working day for many Health care employees. The objective of the survey was to study the frequency and nature of violence and the handling of aggressive behavior by facility management. The cross-sectional study was conducted in 2017, 81 different healthcare facilities and 1984 employees participated. The questionnaire encompassed socio-demographic details, the frequency of physical violence and verbal abuse, consequences of violence and the stress of employees. In the previous twelve months, 94.1% of the employees in the survey had experienced verbal abuse and 69.8% had experienced physical aggression. Acts of aggression were most commonly encountered in hospitals and residential facilities for the disabled. One third of the employees felt under high levels of stress as a result of the incidents. If the workplace prepares effectively, however, this reduces the perceived stress odds ratio (OR) 0.6, 95% CI 0.4⁻0.8). Violence and aggression are very common. Healthcare facilities are increasingly dealing with this topic. Awareness raising is likely to lead to higher incident reporting rates. Good preparation and an open approach to the topic in the facilities have a positive effect on the feeling of stress and work ability.

The Effect of Online Violent Video Games on Levels of Aggression

2014-01-01

Background In recent years the video game industry has surpassed both the music and video industries in sales. Currently violent video games are among the most popular video games played by consumers, most specifically First-Person Shooters (FPS). Technological advancements in game play experience including the ability to play online has accounted for this increase in popularity. Previous research, utilising the General Aggression Model (GAM), has identified that violent video games increase levels of aggression. Little is known, however, as to the effect of playing a violent video game online. Methods/Principal Findings Participants (N = 101) were randomly assigned to one of four experimental conditions; neutral video game—offline, neutral video game—online, violent video game—offline and violent video game—online. Following this they completed questionnaires to assess their attitudes towards the game and engaged in a chilli sauce paradigm to measure behavioural aggression. The results identified that participants who played a violent video game exhibited more aggression than those who played a neutral video game. Furthermore, this main effect was not particularly pronounced when the game was played online. Conclusions/Significance These findings suggest that both playing violent video games online and offline compared to playing neutral video games increases aggression. PMID:25391143

This prospective longitudinal study focused on self-regulatory, social–cognitive, and parenting precursors of individual differences in children’s peer-directed aggression at early school age. Participants were 1993-year-old boys and girls who were reassessed following the transition to kindergarten (5.5–6 years). Peer aggression was assessed in preschool and school settings using naturalistic observations and teacher reports. Children’s self-regulation abilities and theory of mind understanding were assessed during a laboratory visit, and parenting risk (corporal punishment and low warmth/responsiveness) was assessed using interview-based and questionnaire measures. Individual differences in children’s peer aggression were moderately stable across the preschool to school transition. Preschool-age children who manifested high levels of aggressive peer interactions also showed lower levels of self-regulation and theory of mind understanding, and experienced higher levels of adverse parenting than others. Our main finding was that early corporal punishment was associated with increased levels of peer aggression across the transition from preschool to school, as was the interaction between low maternal emotional support and children’s early delays in theory of mind understanding. These data highlight the need for family-directed preventive efforts during the early preschool years. PMID:21262052

Online Mate-Retention Tactics on Facebook Are Associated With Relationship Aggression.

Brem, Meagan J; Spiller, Laura C; Vandehey, Michael A

2015-10-01

A measure of Facebook-related mate-retention tactics was developed to investigate the relationship between online behaviors and intimate partner aggression. One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor analysis yielded four subscales for the Facebook Mate-Retention Tactic Inventory (FMRTI): Care and Affection, Jealousy and Surveillance, Possession Signals, and Punishment of Infidelity Threat. The FMRTI total scores were positively correlated with Facebook jealousy, Facebook surveillance, and use of offline mate-retention tactics. The Jealousy and Surveillance subscale uniquely predicted intimate partner psychological and physical aggression over and above existing measures. Facebook mate-retention tactics fully mediated the relation between Facebook jealousy and both intimate partner psychological and physical aggression. The current study provides preliminary evidence for conceptualizing Facebook as an environment for the use of mate-retention tactics that have real-life implications for intimate partner violence. © The Author(s) 2014.

The study examined associations between workplace aggression (WPA) and psychosomatic symptoms in Palestinian nurses. The 341 nurses, (62% females and 38% males), answered a WHO questionnaire and a psychosomatic symptoms checklist. A total of 27.3% of the nurses reported exposure to WPA of any kind within the last 12 months. After adjusting for covariates, female nurses exposed to WPA of any kind and those exposed to verbal aggression reported a higher symptom score: (1.5; 95% confidence interval [CI]: 0.3, 2.7), and (1.4; 95%CI 0.2, 2.6), respectively, than unexposed females. Male nurses exposed to bullying reported a higher symptom score: (3.2; 95%CI 1.0, 5.5) than unexposed males. Exposure to WPA was associated with higher occurrences of psychosomatic symptoms for both sexes. The female nurses reacted most strongly to verbal aggression or to WPA of any type, while bullying was associated with the male nurses' symptoms. © 2018 Wiley Periodicals, Inc.

This study attempts to assess childhood maltreatment in prison through a hierarchical approach. The hierarchical approach principally aims to disentangle the independent effects of childhood maltreatment upon psychiatric morbidity/personality traits, if any, from the burden that the adverse family conditions have already imposed to the mental health of the maltreated individual-prisoner. To this direction, a conceptual framework with five hierarchical levels was constructed, namely: immutable demographic factors; family conditions; childhood maltreatment (physical abuse, neglect and sexual abuse); personality traits, habits and psychiatric morbidity; prison-related variables. A self-administered, anonymous set (battery) of questionnaires was administered to 173 male prisoners in the Chalkida prison, Greece; 26% of prisoners disclosed childhood maltreatment. Psychiatric condition in the family, parental alcoholism and parental divorce correlated with childhood maltreatment. After adjustment for immutable demographic factors and family conditions, childhood maltreatment was associated with aggression (both in terms of Lifetime History of Aggression and Buss–Perry Aggression Questionnaire scores), illicit substance use, personal history of psychiatric condition, current smoking, impulsivity and alcohol abuse. In conclusion, childhood maltreatment represents a pivotal, determining factor in the life course of male prisoners. Delinquents seem to suffer from long-term consequences of childhood maltreatment in terms of numerous mental health aspects.

The aim of this study was to identify groups of alcohol-dependent individuals differing in the severity of childhood physical, emotional and sexual abuse and to find the personality variables that discriminate between those groups. The study included 90 individuals dependent on alcohol. The following questionnaires were used: the Temperament and Character Inventory (TCI), the Coping Inventory (COPE), the Buss and Perry Aggression Questionnaire (BPAQ), Cattell's IPAT Anxiety Scale, and the Early Trauma Inventory (ETI). Two groups of subjects addicted to alcohol were identified: group 1 with high and group 2 with low childhood physical, emotional and sexual abuse indices. The subjects in Group 1 had significantly higher scores than the subjects in Group 2 on the TCI Temperament scales of NS and HA and lower scores on the TCI character scales of SD, C2 and C4. Group 1 subjects were significantly more likely than those from Group 2 to use avoidant coping strategies; they were also less likely to use problem-focused strategies and had significantly higher scores on general anxiety, overt anxiety, latent anxiety, level of aggression, physical aggression, hostility and anger. The higher severity of childhood physical, emotional and sexual abuse in alcoholics is associated with those personality traits that seem to be crucial for maintaining abstinence and the quality of cooperation in therapy.

Personality traits are meaningful predictors of many significant life outcomes, including mortality. Several studies have investigated the relationship between specific personality traits and driving behaviours, e.g., aggression and speeding, in an attempt to identify traits associated with elevated crash risk. These studies, while valuable, are limited in that they examine only a narrow range of personality constructs and thus do not necessarily reveal which traits in constellation best predict aberrant driving behaviours. The primary aim of this study was to use a comprehensive measure of personality to investigate which personality traits are most predictive of four types of aberrant driving behaviour (Aggressive Violations, Ordinary Violations, Errors, Lapses) as indicated by the Manchester Driver Behaviour Questionnaire (DBQ). We recruited 285 young adults (67% female) from a university in the southeastern US. They completed self-report questionnaires including the DBQ and the Personality Inventory for DSM-5, which indexes 5 broad personality domains (Antagonism, Detachment, Disinhibition, Negative Affectivity, Psychoticism) and 25 specific trait facets. Confirmatory factor analysis showed adequate evidence for the DBQ internal structure. Structural regression analyses revealed that the personality domains of Antagonism and Negative Affectivity best predicted both Aggressive Violations and Ordinary Violations, whereas the best predictors of both Errors and Lapses were Negative Affectivity, Disinhibition and to a lesser extent Antagonism. A more nuanced analysis of trait facets revealed that Hostility was the best predictor of Aggressive Violations; Risk-taking and Hostility of Ordinary Violations; Irresponsibility, Separation Insecurity and Attention Seeking of Errors; and Perseveration and Irresponsibility of Lapses.

Addressing safe-play knowledge and player aggression could potentially improve ice hockey sport safety. To compare (1) safe-play knowledge and aggression between male and female adolescent ice hockey players and (2) head-impact frequency and severity between players with high and low levels of safe-play knowledge and aggression during practices and games. Cohort study. On field. Forty-one male (n = 29) and female (n = 12) adolescent ice hockey players. Players completed the Safe Play Questionnaire (0 = less knowledge, 7 = most knowledge) and Competitive Aggressiveness and Anger Scale (12 = less aggressive, 60 = most aggressive) at midseason. Aggressive penalty minutes were recorded throughout the season. The Head Impact Telemetry System was used to capture head-impact frequency and severity (linear acceleration [g], rotational acceleration [rad/s(2)], Head Impact Technology severity profile) at practices and games. One-way analyses of variance were used to compare safe play knowledge and aggression between sexes. Players were categorized as having high or low safe-play knowledge and aggression using a median split. A 2 × 2 mixed-model analysis of variance was used to compare head-impact frequency, and random-intercept general linear models were used to compare head-impact severity between groups (high, low) and event types (practice, game). Boys (5.8 of 7 total; 95% confidence interval [CI] = 5.3, 6.3) had a trend toward better safe-play knowledge compared with girls (4.9 of 7 total; 95% CI = 3.9, 5.9; F1,36 = 3.40, P = .073). Less aggressive male players sustained significantly lower head rotational accelerations during practices (1512.8 rad/s (2) , 95% CI = 1397.3, 1637.6 rad/s(2)) versus games (1754.8 rad/s (2) , 95% CI = 1623.9, 1896.2 rad/s(2)) and versus high-aggression players during practices (1773.5 rad/s (2) , 95% CI = 1607.9, 1956.3 rad/s (2) ; F1,26 = 6.04, P = .021). Coaches and sports medicine professionals should ensure that athletes of all levels, ages, and sexes have full knowledge of safe play and should consider aggression interventions for reducing head-impact severity among aggressive players during practice.

Exposure to community violence through witnessing or being directly victimized has been associated with conduct problems in a range of studies. However, the relationship between community violence exposure (CVE) and conduct problems has never been studied separately in healthy individuals and individuals with conduct disorder (CD). Therefore, it is not clear whether the association between CVE and conduct problems is due to confounding factors, because those with high conduct problems also tend to live in more violent neighborhoods, i.e., an ecological fallacy. Hence, the aim of the present study was: (1) to investigate whether the association between recent CVE and current conduct problems holds true for healthy controls as well as adolescents with a diagnosis of CD; (2) to examine whether the association is stable in both groups when including effects of aggression subtypes (proactive/reactive aggression), age, gender, site and socioeconomic status (SES); and (3) to test whether proactive or reactive aggression mediate the link between CVE and conduct problems. Data from 1178 children and adolescents (62% female; 44% CD) aged between 9 years and 18 years from seven European countries were analyzed. Conduct problems were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia diagnostic interview. Information about CVE and aggression subtypes was obtained using self-report questionnaires (Social and Health Assessment and Reactive-Proactive aggression Questionnaire (RPQ), respectively). The association between witnessing community violence and conduct problems was significant in both groups (adolescents with CD and healthy controls). The association was also stable after examining the mediating effects of aggression subtypes while including moderating effects of age, gender and SES and controlling for effects of site in both groups. There were no clear differences between the groups in the strength of the association between witnessing violence and conduct problems. However, we found evidence for a ceiling effect, i.e., individuals with very high levels of conduct problems could not show a further increase if exposed to CVE and vice versa. Results indicate that there was no evidence for an ecological fallacy being the primary cause of the association, i.e., CVE must be considered a valid risk factor in the etiology of CD.

To identify groups of caregivers in terms of their use of measures for dealing with resident aggression and the differences between these groups related to their characteristics. Caregivers in nursing home are confronted with a major challenge when faced with the aggressive behaviour of residents. Therefore, the application of recommended measures is important in supporting caregivers and promoting safety for residents. Cross-sectional survey. A total of 804 caregivers working in 21 Swiss nursing homes provided data. The questionnaire used was based on published recommendations regarding management of aggressive behaviour and amendments by experts. The most widely used measure aimed to calm down the resident and to understand the meaning of aggressive behaviour. Physical activities were applied by around 50% of the respondents, and interdisciplinary case reviews as well as standardised instruments for assessment and documentation were used by <50%. Caregiver characteristics such as employment level, support from superiors, institutionalised support for affected caregivers and training in aggression management are associated with their use of recommended measures. Furthermore, caregivers' competence in empathising with the residents' perspective in connection with their professional experience has a positive influence on applying recommended measures. Caregivers use multifaceted measures in understanding the meaning of underlying aggression, but there is a certain failure to use standardised instruments. Caregivers differ significantly in the frequency of their application of recommended measures. Support from superiors and assistance for affected caregivers positively influence their use of measures, whereas training in aggression management leads to less use. Findings show the importance of support from superiors and institutionalised assistance for affected caregivers. Caregiver competence in empathising with the residents' perspective is important in using person-centred approaches in the care of residents with aggressive behaviour. © 2013 John Wiley & Sons Ltd.

2013-02-01

In 2002, Caspi and colleagues provided the first epidemiological evidence that genotype may moderate individuals' responses to environmental determinants. However, in a correlational study great care must be taken to ensure the proper estimation of the causal relationship. Here, a randomized experiment was performed to test the hypothesis that the MAOA gene promoter polymorphism (MAOA-LPR) interacts with environmental adversity in determining aggressive behavior using laboratory analogs of real-life conditions. A sample of 57 Caucasian male students of Catalan and Spanish origin was recruited at the University of Barcelona. Ostracism, or social exclusion, was induced as environmental adversity using the Cyberball software. Laboratory aggression was assessed with the Point Subtraction Aggression Paradigm (PSAP), which was used as an analog of antisocial behavior. We also measured aggressiveness by means of the reduced version of the Aggression Questionnaire. The MAOA-LPR polymorphism showed a significant effect on the number of aggressive responses in the PSAP (F(1,53) = 4.63, P = 0.03, partial η(2) = 0.08), as well as social exclusion (F(1,53) = 8.03, P = 0.01, partial η(2) = 0.13). Most notably, however, we found that the MAOA-LPR polymorphism interacts significantly with social exclusion in order to provoke aggressive behavior (F(1,53) = 4.42, P = 0.04, partial η(2) = 0.08), remarkably, the low-activity allele of the MAOA-LPR polymorphism carriers in the ostracized group show significantly higher aggression scores than the rest. Our results support the notion that gene-environment interactions can be successfully reproduced within a laboratory using analogs and an appropriate design. We provide guidelines to test gene-environment interactions hypotheses under controlled, experimental settings. © 2012 The Authors.

The Training with Aggressive Children (Petermann & Petermann, 2008) was integrated into the setting of a child welfare service. This study examined, if mental health care of aggressive children in child welfare settings can be improved, compared the effectiveness of a combination of the training and child welfare intervention after six months with effects of the TAK. 25 Children with conduct problems (24 boys, one girl) aged 7;6 to 13;0 years participated in the study. A pretest-follow up comparison of parent ratings on the Child Behavior Checklist (CBCL) documented a large reduction of aggressive-delinquent behaviour and social problems in the training and child welfare group. Furthermore, conduct and peer relationship problems decreased essentially on the Strengths and Difficulties Questionnaire (SDQ). By reducing conduct, attention and social problems, and delinquent behaviour, the therapeutic outcome of the training and child welfare group was clearly superior to training group. In comparison to the training, the combination of child welfare and training seemed to reduce a wider range of behavioural problems more effectively. This indicates that combined intervention programs can optimize mental health care of aggressive children.

Sex, violence, & rock n' roll: Longitudinal effects of music on aggression, sex, and prosocial behavior during adolescence.

2015-06-01

The current study examined longitudinal associations between listening to aggression, sex, and prosocial behavior in music on a number of behavioral outcomes across a one-year period during adolescence. Adolescents (N = 548, M age = 15.32, 52% female) completed a number of questionnaires on musical preferences, general media use, aggression, sexual outcomes, and prosocial behavior at two different time points separated by about one year. Using structural equation modeling to analyze the data, results revealed that listening to aggression in music was associated with increased aggression and decreased prosocial behavior over time, even when controlling for initial levels of these behaviors. Listening to sexual content in music was associated with earlier initiation of sexual intercourse and a trend for a higher number of sexual partners (reported at Time 2). Prosocial behavior in music was not associated with any behavioral outcome longitudinally. Collectively, these results suggest that listening to certain types of content in music can have a longitudinal effect on behavior during adolescence.

Negative correlates of computer game play in adolescents.

PubMed

Colwell, J; Payne, J

2000-08-01

There is some concern that playing computer games may be associated with social isolation, lowered self-esteem, and aggression among adolescents. Measures of these variables were included in a questionnaire completed by 204 year eight students at a North London comprehensive school. Principal components analysis of a scale to assess needs fulfilled by game play provided some support for the notion of 'electronic friendship' among boys, but there was no evidence that game play leads to social isolation. Play was not linked to self-esteem in girls, but a negative relationship was obtained between self-esteem and frequency of play in boys. However, self-esteem was not associated with total exposure to game play. Aggression scores were not related to the number of games with aggressive content named among three favourite games, but they were positively correlated with total exposure to game play. A multiple regression analysis revealed that sex and total game play exposure each accounted for a significant but small amount of the variance in aggression scores. The positive correlation between playing computer games and aggression provides some justification for further investigation of the causal hypothesis, and possible methodologies are discussed.

The present study examined mothers' use of corporal punishment and adolescents' aggression as predictors of mother-youth conflict during early adolescence. Particular attention was given to the potential mediating role that adolescents' hostile attributions of intent (HAI) regarding mothers' behavior might play in connections between corporal punishment, youth aggression, and mother-adolescent conflict for European American (EA) and African American (AA) youth. Data were collected from 268 12- to 14-year-olds (154 European American; 114 African American; 133 girls; 135 boys) and their mothers over a period of 2 years. Questionnaires completed by both mothers and adolescents were used to assess maternal corporal punishment and adolescent aggression, and interviews concerning hypothetical situations were used to assess adolescent HAI in year one. In both year one and year two mother-adolescent conflict was observed in a laboratory interaction session. Data revealed that adolescent HAI mediated the link between maternal corporal punishment and mother-adolescent conflict for EA, but not AA youth. Adolescents' HAI mediated the link between adolescent aggression and mother-adolescent conflict for both EA and AA families. Published by Elsevier Ltd.

Early weaning increases aggression and stereotypic behaviour in cats.

Behaviour problems are common in companion felines, and problematic behaviour may be a sign of chronic stress. In laboratory animals, early weaning increases the risk for aggression, anxiety, and stereotypic behaviour. However, very few studies have focused on early weaning in one of the world's most popular pets, the domestic cat, although weaning soon after the critical period of socialisation is common practice. To study the effects of early weaning (<12 weeks) on behaviour, a large data set (N = 5726, 40 breeds) was collected from home-living domestic cats through a questionnaire survey. The results show that weaning before 8 weeks of age increases the risk for aggression, but not fearful behaviour. Moreover, cats weaned after 14 weeks of age have a lower probability for aggression towards strangers than early weaned cats and a lower probability for stereotypic behaviour (excessive grooming) than cats weaned at 12 weeks. The effect of weaning age on stereotypic behaviour is partially explained by the effects on aggression. These findings indicate that early weaning has a detrimental effect on behaviour, and suggest delayed weaning as a simple and inexpensive approach to significantly improve the welfare of millions of domestic cats.

In psychiatry, most of the focus on patient aggression has been in adolescent and adult inpatient settings. This behaviour is also common in elderly people with mental illness, but little research has been conducted into this problem in old age psychiatry settings. The attitudes of clinical staff toward aggression may affect the way they manage this behaviour. The purpose of this study was to examine the attitudes of clinical staff toward the causes and management of aggression in acute old age psychiatry inpatient settings. A convenience sample of clinical staff were recruited from three locked acute old age psychiatry inpatient units in Melbourne, Australia. They completed the Management of Aggression and Violence Scale, which assessed the causes and managment of aggression in psychiatric settings. Eighty-five staff completed the questionnaire, comprising registered nurses (61.1%, n = 52), enrolled nurses (27.1%, n = 23) and medical and allied health staff (11.8%, n = 10). A range of causative factors contributed to aggression. The respondents had a tendency to disagree that factors directly related to the patient contributed to this behaviour. They agreed patients were aggressive because of the environment they were in, other people contributed to them becoming aggressive, and patients from certain cultural groups were prone to these behaviours. However, there were mixed views about whether patient aggression could be prevented, and this type of behaviour took place because staff did not listen to patients. There was agreement medication was a valuable approach for the management of aggression, negotiation could be used more effectively in such challenging behaviour, and seclusion and physical restraint were sometimes used more than necessary. However, there was disagreement about whether the practice of secluding patients should be discontinued. Aggression in acute old age psychiatry inpatient units occurs occasionally and is problematic. A range of causative factors contribute to the onset of this behaviour. Attitudes toward the management of aggression are complex and somewhat contradictory and can affect the way staff manage this behaviour; therefore, wide-ranging initiatives are needed to prevent and deal with this type of challenging behaviour.

In parts of rural China male-biased sex ratios at birth, combined with out-migration of women, have led to highly male-biased adult sex ratios, resulting in large numbers of men being unable to marry, in a culture where marriage and reproduction are an expectation. The aim of this study was to test the hypotheses that older unmarried men are more predisposed to depression, low self-esteem and aggression than both those who are married, and those who are younger and unmarried. Self-completion questionnaires were administered among men aged 20-40 in 48 villages in rural Guizhou province, southwestern China. Tools used included the Beck Depression Inventory, the Rosenberg's Self-esteem Scale and the Bryant-Smith Aggression Questionnaire. Regression models assessed psychological wellbeing while adjusting for socio-demographic variables. Completed questionnaires were obtained from 957 never-married men, 535 married men aged 30-40, 394 partnered men and 382 unpartnered men aged 20-29. After adjusting for socio-demographic variables, never-married men were more predisposed to depression ( p < 0.05), aggression ( p < 0.01), low self-esteem ( p < 0.05) and suicidal tendencies ( p < 0.001). All the psychological measures deteriorated with age in never-married men. In contrast, married men remained stable on these dimensions with age. Never-married men are a psychologically highly vulnerable group in a society where marriage is an expectation. Since the highest birth sex-ratio cohorts have not yet reached reproductive age, the social tragedy of these men will last for at least another generation.This article is part of the themed issue 'Adult sex ratios and reproductive decisions: a critical re-examination of sex differences in human and animal societies'. © 2017 The Authors.

To establish if voluntary whole-blood donors and compensated platelet donors and plasma donors may differ in their motivation to donate, altruism, aggression and autoaggression. Whole-blood (n=51), platelet (n=52) and plasma donors (n=48) completed a battery of validated questionnaires while waiting to donate. Bivariate and multivariate analyses of variance and t-tests were performed to detect differences between groups as noted. Altruism (mean=40.2) was slightly higher in whole-blood donors than in platelet (mean=38.3) and plasma donors (mean=39.1) (p=0.07). Blood donors (mean=2.8) scored lower in the spontaneous aggression measure than platelet (mean=4.1) and plasma donors (mean=4.4) (p=0.01). Plasma donors (mean=4.9) had higher auto-aggression than whole-blood donors and platelet donors (mean for both groups=3.4) (p=0.01). Differences between the three groups were mediated by sociodemographic variables (MANCOVA). Whole-blood donors donated to help others, platelet and plasma donors mostly to receive the compensation. However, those platelet and plasma donors, who would continue to donate without compensation were similar in altruism and aggression to whole-blood donors. While most platelet donors and plasma donors were motivated by the compensation, those who stated that they would continue to donate without compensation had altruism and aggression scores similar to voluntary whole-blood donors.

Background: The present study compared people with depressive symptoms and people without depressive symptoms with reference to their coping styles, level of aggression and interpersonal conflicts. Methods: A purposive sample of 128 people (64 depressed and 64 normal controls)was selected from four different teaching hospitals of Lahore. Both the groups were matched on four demographic levels i.e. age, gender, education and monthly income. Symptom Checklist-R was used to screen out depressed and non-depressed people. The Brief COPE, the Aggression Questionnaire and the Bergen Social Relationship Scale were used to assess coping styles, aggression and interpersonal conflicts respectively. The Independent t-test was used to compare the groups. Binary logistic Regression was also carried out to predict the role of research variables in causing depression. Results: The results showed that level of aggression and interpersonal conflict was significantly more in people with depressive symptoms as compared to control group. On the other hand control group was using more adaptive coping styles than people with depressive symptoms but no difference was found in the use of maladaptive coping styles. Conclusion: The present findings revealed that coping styles, aggression and interpersonal conflicts play important role in depression. Therefore, these dimensions must be considered while dealing with the depressive patients. Implications for preventive work are also discussed in the light of previous researches. PMID:24688956

Aggression is one of the negative components of emotion and it is usually considered to be the outcome of the activity of the Behavioral Inhibition and the Behavioral Activation System (BIS/BAS): components which can be considered as predisposing factors for personality differences. Therefore, the purpose of this study was to investigate the relationship between brain behavioral systems and the characteristics of the five factor model of personality with aggression among students. The present study has a correlation descriptive design. The research population included all of the Razi University students in the academic year of 2012-2013. The sampling was carried out with a random stratified method and 360 people (308 female and 52 male) were studied according to a table of Morgan. The study instruments were Buss and Perry Aggression Questionnaire, NEO Personality Inventory (Short Form), and Carver and White scale for BAS/BIS. Finally, SPSS20 was utilized to analyze the data using Pearson correlation, regression analysis, and canonical correlation. The data showed a significant positive relationship between the neurosis and agreeableness personality factors with aggression; but there is a significant negative relationship between the extroversion, openness, and conscientiousness personality factors with aggression. Furthermore, there is a significant positive relationship between all the components of brain behavioral systems (impulsivity, novelty seeking, sensitivity, tender) and aggression. The results of regression analysis indicated the personality characteristics and the brain behavioral systems which can predict 29 percent of the changes to aggression, simultaneously. According to a predictable level of aggressiveness by the personality characteristics and brain behavioral systems, it is possible to identify the personality characteristics and template patterns of brain behavioral systems for the students which be presented to them as a necessary training in order to control and manage of anger and aggression. © 2016 KUMS, All rights reserved.

Previous research has focused primarily on corporal punishment as a cause and adolescents' physical aggression as an outcome. However, there is a large gap in knowledge of the potentially bidirectional association and explanatory mechanism underlying the association between corporal punishment and physical aggression. The current study, using a longitudinal design across three time points (the fall semester of 7th grade, the fall of 8th grade, and the fall of 9th grade), aimed to a) examine the reciprocal processes between corporal punishment and physical aggression, and b) explore whether deviant peer affiliation may explain such reciprocal connections. Only adolescents participating in all the three time points were included in this study, resulting in a final sample of 342 adolescents (175 boys, 167 girls) who completed questionnaires regarding corporal punishment, deviant peer affiliation, and aggression. Gender, age and socioeconomic status were controlled for in the analyses. Autoregressive cross-lagged models showed that the results did not support the direct reciprocal effect between corporal punishment and physical aggression among Chinese adolescents. A direct longitudinal link from corporal punishment to physical aggression was found, however, the inverse association was not significant. Moreover, regarding the longitudinal underlying process, in one direction, corporal punishment at 7th grade predicted higher levels of deviant peer affiliation at 8th grade. In turn, higher deviant peer affiliation at 8th grade predicted increased physical aggression at 9th grade. At the same time, in the other direction, adolescent physical aggression at 7th grade significantly predicted deviant peer affiliation at 8th grade. In turn, higher deviant peer affiliation at 8th grade predicted decreased corporal punishment at 9th grade. Identifying the direct and underlying reciprocal processes between corporal punishment and adolescent physical aggression has important implications for an integrative framework of theory and prevention.

Purpose Non-suicidal self-injury (NSSI) in adolescent has drawn increasing attention because it is associated with subsequent depression, drug abuse, anxiety disorders, and suicide. In the present study, we aimed to estimate the prevalence of non-suicidal self-injury (NSSI) in a school-based sample of Chinese adolescents and to explore the association between aggression and NSSI. Methods This study was part of a nationwide study on aggression among adolescents in urban areas of China. A sample of 2907 school students including 1436 boys and 1471 girls were randomly selected in Guangdong Province, with their age ranging from 10 to 18 years old. NSSI, aggression, emotional management and other factors were measured by self-administrated questionnaire. Multinomial logistic regression was used to estimate the association between aggression and NSSI, after adjustment for participants’ emotional management, and other potential confounding variables. Results The one year self-reported prevalence of NSSI was 33.6%. Of them, 21.7% engaged in ‘minor NSSI’, 11.9% in ‘moderate/severe NSSI’. 96.9% of self-injuries engaged in one to five different types of NSSI in the past year. Hostility, verbal and indirect aggression was significantly associated with self-reported NSSI after adjusting for other potential factors both in ‘minor NSSI’ and ‘moderate/severe NSSI’. Hostility, verbal and indirect aggression was significantly associated with greater risk of ‘minor NSSI’ and ‘moderate/severe NSSI’ in those who had poor emotional management ability. Conclusion These findings highlight a high prevalence of NSSI and indicate the importance of hostility, verbal and indirect aggression as potentially risk factor for NSSI among Chinese adolescents.

Background: Aggression is defined as behaviors intended to hurt, harm, or injure another person. Aggression is by no means a new concern in human society, especially in youth. Universities are among the institutions in which most of the members are young people and because of facing with various personal and social stressors, the students usually experience high level of stress. Objectives: This study aimed to determine aggression among university students and its association with their personal, family, and social characteristics. Materials and Methods: This cross-sectional, analytic study was conducted on a representative sample (n = 809) of university students (1 state university and 2 private universities) locating in Gonabad, Iran in 2012. Using proportional to size stratified sampling, we selected the respondents and gathered the required data using a valid and reliable questionnaire. The data were entered into SPSS (version 20) and analyzed through t test, ANOVA, and regression model. Results: A total of 381 (47.2%) male and 428 (52.8%) female students participated in the study. Mean (SD) age of the respondents was 21.79 (2.86) years. Overall mean aggression score (SD) in the students was 72.45 (15.49) and this score for in dorm and out of dorm students was 74.31 (15.59) and 70.93 (15.23), respectively. There were significant associations between the mean aggression score of dormitory students and sex (P = 0.004), age (P = 0.044), and type of the university (P = 0.039). On the other hand, there was no significant association between all independent factors and mean aggression score of students living out of dorm. Conclusions: Regarding the control of aggressive behaviors, paying attention to male, young students living in dormitory, especially in non-governmental universities has the highest priority.

The aim of the study was to investigate if the feline vomeronasal organ (VNO) can be affected by inflammatory lesions and if these changes are associated with behavioural alterations. VNOs from 20 cats were sampled during necropsy, submitted for routine tissue processing and stained with haematoxylin and eosin for histopathological evaluation. For the 20 cats, data on the presence of aggressive behaviours towards cats or humans were collected by questionnaire survey at the point of death. Inflammatory lesions were classified depending on the duration of the process as acute or chronic, both in vomeronasal sensory epithelium (VNSE) and in non-sensory epithelium (NSE). Fisher's exact test was used to compare VNO inflammation with behavioural data. The VNSE was inflamed in 11/20 VNOs (55%) while the NSE was inflamed in 13/20 (65%). Overall, the VNO was affected by inflammation in 14/20 (70%) cats, and all the lesions were classified as chronic. Five out of 20 cats (25%) had documented intraspecific aggressive behaviours and 8/20 (40%) had shown aggression towards humans. Fisher's exact test showed a statistically significant correlation between inflammation of the VNSE and intraspecific aggression (P = 0.038). No statistically correlations were observed between VNSE inflammation and aggression towards humans and between NSE inflammation and aggression towards cats or humans. Our results show, for the first time, the existence of vomeronasalitis in animals and its possible association with intraspecific aggressive behaviours. The inflammatory microenvironment could impair VNSE functionality, causing intraspecific communication alterations, probably through a reduction in chemical communication action and perception. Owing to the pivotal role of the VNO in the social life of cats and other species, this report provides a rationale to further investigate this disease in relation to a variety of behavioural disorders. © The Author(s) 2015.

Rough-and-tumble play and the regulation of aggression: an observational study of father-child play dyads.

2009-01-01

Rough-and-tumble play (RTP) is a common form of play between fathers and children. It has been suggested that RTP can contribute to the development of selfregulation. This study addressed the hypothesis that the frequency of father-child RTP is related to the frequency of physically aggressive behavior in early childhood. This relationship was expected to be moderated by the dominance relationship between father and son during play. Eighty-five children between the ages of 2 and 6 years were videotaped during a free-play session with their fathers in their homes and questionnaire data was collected about father-child RTP frequency during the past year. The play dyads were rated for the degree to which the father dominated play interactions. A significant statistical interaction revealed that RTP frequency was associated with higher levels of physical aggression in children whose fathers were less dominant. These results indicate that RTP is indeed related to physical aggression, though this relationship is moderated by the degree to which the father is a dominant playmate.

Aggressive behavior in adolescents, along with drug use, has become one of the great issues in education in recent years, among other things, due to its relationship with school failure and delinquency. The purpose of this paper was to find out whether social support fulfils a basic role in decision-making on drug use and the behavior of adolescents. 822 high school students participated in the study (M = 14.84, SD = 0.87). Data were collected with the Peer Conflict Scale and the Multidimensional Scale of Perceived Social Support, and an ad hoc questionnaire on drug use. The results show that drug use is significantly related to reactive and proactive aggressive behavior. It was also observed that higher use is significantly related to perceived social support by the peer group, and less support by family. It was shown that substance use is related to perceived social support by the adolescent’s peer group and to aggressive behavior. It is therefore necessary to intervene in both respects to avoid the presence of substance use in schools.

Adolescents in institutionalized care are at a particularly high risk of exhibiting sexually aggressive behavior including sexual harassment. So far, however, studies about the prevalence of sexually aggressive behavior in institutions are lacking. In this survey, 322 adolescents (43% female, average age 16.7 years) from 32 residential care facilities and boarding schools across Germany were asked about sexually aggressive behavior via a standardized questionnaire. Overall, 23.5% of the participants engaged in some form of sexually aggressive behavior in their lives, and 4.6% reported having committed a sexual assault with (actual or attempted) penetration. A closer look at the circumstances of those offenses shows that the victims were in most cases acquainted with and of the same age as the offenders, that threats and violence were used in some cases, and especially in the case of actual or attempted penetration, and that only a minority of offenders suffered any consequences for their acts. The implementation of protective measures for institutions and the treatment of adolescents in institutions will be discussed.

Parallel Syndromes: Two Dimensions of Narcissism and the Facets of Psychopathic Personality in Criminally-Involved Individuals

PubMed Central

2012-01-01

Little research has examined different dimensions of narcissism that may parallel psychopathy facets in criminally-involved individuals. The present study examined the pattern of relationships between grandiose and vulnerable narcissism, assessed using the Narcissistic Personality Inventory-16 and the Hypersensitive Narcissism Scale, respectively, and the four facets of psychopathy (interpersonal, affective, lifestyle, and antisocial) assessed via the Psychopathy Checklist: Screening Version (PCL:SV). As predicted, grandiose and vulnerable narcissism showed differential relationships to psychopathy facets, with grandiose narcissism relating positively to the interpersonal facet of psychopathy and vulnerable narcissism relating positively to the lifestyle facet of psychopathy. Paralleling existing psychopathy research, vulnerable narcissism showed stronger associations than grandiose narcissism to 1) other forms of psychopathology, including internalizing and substance use disorders, and 2) self- and other-directed aggression, measured using the Life History of Aggression and the Forms of Aggression Questionnaire. Grandiose narcissism was nonetheless associated with social dysfunction marked by a manipulative and deceitful interpersonal style and unprovoked aggression. Potentially important implications for uncovering etiological pathways and developing treatment interventions for these disorders in externalizing adults are discussed. PMID:22448731

The purposes of this study were to develop and validate the Empathic-Affective Response Scale, and to examine the relationship of empathic-affective responses with prosocial behaviors and aggressive behaviors. Undergraduate students (N = 443) participated in a questionnaire study. The results of factor analysis indicated that empathic-affective responses involved three factors: (a) sharing and good feeling toward others' positive affect, (b) sharing of negative affect and (c) sympathy toward others' negative affect. Correlations with other empathy-related scales and internal consistency suggested that this scale has satisfactory validity and reliability. Cluster analysis revealed that participants were clustered into four groups: high-empathic group, low-empathic group, insufficient positive affective response group and insufficient negative affective response group. Additional analysis showed the frequency of prosocial behaviors in high-empathic group was highest in all groups. On the other hand, the frequency of aggressive behaviors in both insufficient positive affective response group and low-empathic group were higher than others' groups. The results indicated that empathic-affective responses toward positive affect are also very important to predict prosocial behaviors and aggressive behaviors.

This study evaluated an intervention for patient-handling equipment aimed to improve nursing staffs' use of patient handling equipment and improve their general health, reduce musculoskeletal problems, aggressive episodes, days of absence and work-related accidents. As a controlled before-after study, questionnaire data were collected at baseline and 12-month follow-up among nursing staff at intervention and control wards at two hospitals. At 12-month follow-up, the intervention group had more positive attitudes towards patient-handling equipment and increased use of specific patient-handling equipment. In addition, a lower proportion of nursing staff in the intervention group had experienced physically aggressive episodes. No significant change was observed in general health status, musculoskeletal problems, days of absence or work-related accidents. The intervention resulted in more positive attitudes and behaviours for safe patient-handling and less physically aggressive episodes. However, this did not translate into improved health of the staff during the 12-month study period. Copyright © 2016 Elsevier Ltd. All rights reserved.

Context:  Addressing safe-play knowledge and player aggression could potentially improve ice hockey sport safety. Objectives:  To compare (1) safe-play knowledge and aggression between male and female adolescent ice hockey players and (2) head-impact frequency and severity between players with high and low levels of safe-play knowledge and aggression during practices and games. Design:  Cohort study. Setting:  On field. Patients or Other Participants:  Forty-one male (n = 29) and female (n = 12) adolescent ice hockey players. Intervention(s):  Players completed the Safe Play Questionnaire (0 = less knowledge, 7 = most knowledge) and Competitive Aggressiveness and Anger Scale (12 = less aggressive, 60 = most aggressive) at midseason. Aggressive penalty minutes were recorded throughout the season. The Head Impact Telemetry System was used to capture head-impact frequency and severity (linear acceleration [g], rotational acceleration [rad/s2], Head Impact Technology severity profile) at practices and games. Main Outcome Measure(s):  One-way analyses of variance were used to compare safe play knowledge and aggression between sexes. Players were categorized as having high or low safe-play knowledge and aggression using a median split. A 2 × 2 mixed-model analysis of variance was used to compare head-impact frequency, and random-intercept general linear models were used to compare head-impact severity between groups (high, low) and event types (practice, game). Results:  Boys (5.8 of 7 total; 95% confidence interval [CI] = 5.3, 6.3) had a trend toward better safe-play knowledge compared with girls (4.9 of 7 total; 95% CI = 3.9, 5.9; F1,36 = 3.40, P = .073). Less aggressive male players sustained significantly lower head rotational accelerations during practices (1512.8 rad/s2, 95% CI = 1397.3, 1637.6 rad/s2) versus games (1754.8 rad/s2, 95% CI = 1623.9, 1896.2 rad/s2) and versus high-aggression players during practices (1773.5 rad/s2, 95% CI = 1607.9, 1956.3 rad/s2; F1,26 = 6.04, P = .021). Conclusions:  Coaches and sports medicine professionals should ensure that athletes of all levels, ages, and sexes have full knowledge of safe play and should consider aggression interventions for reducing head-impact severity among aggressive players during practice.

Research into online gaming has steadily increased over the last decade, although relatively little research has examined the relationship between online gaming addiction and personality factors. This study examined the relationship between a number of personality traits (sensation seeking, self-control, aggression, neuroticism, state anxiety, and trait anxiety) and online gaming addiction. Data were collected over a 1-month period using an opportunity sample of 123 university students at an East Midlands university in the United Kingdom. Gamers completed all the online questionnaires. Results of a multiple linear regression indicated that five traits (neuroticism, sensation seeking, trait anxiety, state anxiety, and aggression) displayed significant associations with online gaming addiction. The study suggests that certain personality traits may be important in the acquisition, development, and maintenance of online gaming addiction, although further research is needed to replicate the findings of the present study.

This work is a study of the personality of the wives of alcoholic patients composed by means of a structures interview, the MMPI personality questionnaire and the Instrument I used to evaluate aggressivity. Among the discoveries made, we must emphasize that 20% of the wives knew of their partner's excessive alcohol consumption before marriage, while married, 75% were victims of some kind of violent incident, 43% had personal psychopathological backgrounds, 15% were "repeaters wives" "those who had alcoholic parents). In the MMPI test, these women represent a significantly high profile, in which the scales Hs, D and Hy are the highest, amongst which their most outstanding personality traits include passivity, dependency and insecurity. Furthermore, those wives whose husbands have had relapses, represent a higher Pd scale than the other group. The Instrument I used to evaluate aggressivity also emphasizes this passive-aggressive tendency in the wives.

This study investigated time series changes and relationships of affects, cognitions, and behaviors immediately, a few days, and a week after anger episodes. Two hundred undergraduates (96 men, and 104 women) completed a questionnaire. The results were as follows. Anger intensely aroused immediately after anger episodes, and was rapidly calmed as time passed. Anger and depression correlated in each period, so depression was accompanied with anger experiences. The results of covariance structure analysis showed that aggressive behavior was evoked only by affects (especially anger) immediately, and was evoked only by cognitions (especially inflating) a few days after the episode. One week after the episode, aggressive behavior decreased, and was not influenced by affects and cognitions. Anger elicited all anger-expressive behaviors such as aggressive behavior, social sharing, and object-displacement, while depression accompanied with anger episodes elicited only object-displacement.

Development and Validation of Videotaped Scenarios

Researchers using scenarios often neglect to validate perceived content and salience of embedded stimuli specifically with intended participants, even when such meaning is integral to the study. For example, sex and aggression stimuli are heavily influenced by culture, so participants may not perceive what researchers intended in sexual aggression scenarios. Using four studies, the authors describe the method of scenario validation to produce two videos assessing alcohol-related sexual aggression. Both videos are identical except for the presence in one video of antiforce cues that are extremely salient to the young heterosexual men. Focus groups and questionnaires validate these men's perceptions that (a) the woman was sexually interested, (b) the sexual cues were salient, (c) the antiforce cues were salient (antiaggression video only), and (e) these antiforce cues inhibited acceptance of forced sex. Results show the value of carefully selecting and validating content when assessing socially volatile variables and provide a useful template for developing culturally valid scenarios. PMID:18252938

Conflict and conflict resolution in intimate relationships are not only among the most important factors influencing relationship satisfaction but are also seen in association with clinical symptoms. Styles of conflict will be assessed in patients suffering from panic disorder with and without agoraphobia, in alcoholics and in patients suffering from rheumatoid arthritis. 176 patients and healthy controls filled out the Styles of Conflict Inventory and questionnaires concerning severity of clinical symptoms. A cluster analysis revealed 5 types of conflict management. Healthy controls showed predominantely assertive and constructive styles, patients with panic disorder showed high levels of cognitive and/or behavioral aggression. Alcoholics showed high levels of repressed aggression, and patients with rheumatoid arthritis often did not exhibit any aggression during conflict. 5 Clusters of conflict pattern have been identified by cluster analysis. Each patient group showed considerable different patterns of conflict management.

Excessive computer game playing: evidence for addiction and aggression?

Grüsser, S M; Thalemann, R; Griffiths, M D

2007-04-01

Computer games have become an ever-increasing part of many adolescents' day-to-day lives. Coupled with this phenomenon, reports of excessive gaming (computer game playing) denominated as "computer/video game addiction" have been discussed in the popular press as well as in recent scientific research. The aim of the present study was the investigation of the addictive potential of gaming as well as the relationship between excessive gaming and aggressive attitudes and behavior. A sample comprising of 7069 gamers answered two questionnaires online. Data revealed that 11.9% of participants (840 gamers) fulfilled diagnostic criteria of addiction concerning their gaming behavior, while there is only weak evidence for the assumption that aggressive behavior is interrelated with excessive gaming in general. Results of this study contribute to the assumption that also playing games without monetary reward meets criteria of addiction. Hence, an addictive potential of gaming should be taken into consideration regarding prevention and intervention.

The relation between narcissism and laboratory aggression is not contingent on environmental cues of competition.

Narcissism has been robustly linked to self-report and lab-based measures of aggression. However, less is known about the role that a competitive context may play in the relations found between narcissism and aggression as measured in behavioral paradigms. In circumstances of competition, narcissistic individuals may be particularly attuned to external indicators of status and use aggression as a way of asserting power and a motivation to "win," rather than to do harm. The goal of the present study was to test the role of competition in understanding the relation between narcissism and related traits (i.e., psychopathy) and aggression by manipulating cues of competition. First, participants (N = 220) completed questionnaires to assess levels of trait narcissism and associated variables (e.g., psychopathy, five-factor model traits, and self-esteem). In a separate session, participants were randomly assigned to interact with an ostensible confederate under the guise of either a competitive or noncompetitive interaction, and then were given the opportunity to administer electric shocks to their partner. Results suggest that the antagonistic and grandiose features of narcissism were significantly related to aggression in both conditions, as was the antagonism factor of psychopathy and (low) Agreeableness dimension of the five-factor model. However, tests of moderation found no significant interaction effects between narcissism and condition in the hypothesized direction (and a few in the opposite direction such that narcissism was more strongly related in the noncompetition condition). Findings are discussed in terms of the importance of antagonism in predicting antisocial outcomes such as aggression. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

2017-02-01

A computerized version of an assessment of Social-Emotional Information Processing (SEIP) using audio-video film stimuli instead of written narrative vignettes was developed for use in adult participants. This task allows for an assessment of encoding or relevant/irrelevant social-emotional information, attribution bias, and endorsement of appropriate, physically aggressive, and relationally aggressive responses to aversive social-emotional stimuli. The psychometric properties of this Video-SEIP (V-SEIP) assessment were examined in 75 healthy controls (HC) and in 75 individuals with DSM-5 Intermittent Explosive Disorder (IED) and were also compared with the original questionnaire (SEIP-Q) version of the task (HC=26; IED=26). Internal consistency, inter-rater reliability, and test-retest properties of the V-SEIP were good to excellent. In addition, IED participants displayed reduced encoding of relevant information from the film clips, elevated hostile attribution bias, elevated negative emotional response, and elevated endorsement of physically aggressive and relationally aggressive responses to the ambiguous social-emotional stimuli presented in the V-SEIP. These data indicate that the V-SEIP represents a valid and comprehensive alternative to the paper-and-pencil assessment of social-emotional information processing biases in adults. Copyright © 2016.

Although many researchers have explored the topic of dating violence, limited attention has been paid to female perpetrators. Very little research has examined variables that facilitate aggression for females in dating relationships. In an effort to investigate distinct types of violent behavior, the present study separated females who experience dating violence into three categories (bi-directional aggression, perpetrator-only, and victim-only) and compared them with a control group not previously exposed to interpersonal violence. The purpose of this study was to examine variables that discriminate violent females from non-violent females. Variables that were hypothesized to be associated with aggressive behavior and investigated in the current study were interparental aggression, self-esteem, love attitudes, and alcohol use. Three hundred female college students responded to multiple self-report questionnaires examining psychological correlates of dating violence. Females in the bi-directional aggression group were more likely to have witnessed their father abuse their mother and scored significantly lower on a measure of self-esteem than non-violent controls. Females in the control group demonstrated higher scores on a measure of mature and selfless love style than did the victim or perpetrator-only participants. There were no significant group differences regarding general alcohol consumption. Implications for prevention and intervention are presented and discussed.

Driving on Indian roads is a stressful experience. A lacuna of research on aggressive driving experiences in the Indian set-up highlights the need to address this growing concern for individuals, society and mental health professionals. To explore and compare driving-related anger triggers and anger expression among high- and low-angry Indian drivers. Two hundred randomly chosen drivers from the city of Delhi were administered a semi-structured questionnaire intended to understand driving-related aggression. Honking, overtaking from the wrong side, loud music in other cars and hot and humid climate significantly increased the risk of experiencing anger among high-angry drivers. High-angry drivers were significantly more likely to engage in direct and aggressive expression of anger, including overtaking, verbal abuse, yelling and arguing, not giving space to other drivers, fighting, and hitting and bumping other cars in protest. Passive anger expressions such as holding grudges against other drivers and eating or drinking something to cool down were significantly more likely to be used by low-angry drivers. Drivers who are high on anger have a significantly higher risk of experiencing anger triggered by a variety of individual and environmental factors on Indian roads and are more susceptible to engage in aggressive driving behaviour.

Direct and indirect aggression and victimization in adolescents - associations with the development of psychological difficulties.

PubMed

Lundh, Lars-Gunnar; Daukantaité, Daiva; Wångby-Lundh, Margit

2014-01-01

Previous research has established that direct and indirect forms of aggression differ in their association with gender and type of psychological difficulties. One purpose of the present study was to test if the same applies to direct and indirect victimization. A second purpose was to study these associations not only cross-sectionally (as in most previous research) but also longitudinally. A third purpose was to test the hypotheses that there are prospective bidirectional associations not only between victimization and psychological difficulties (which has been shown in previous research), but also between aggression and psychological difficulties, and that direct and indirect forms of aggression and victimization show different associations with different types of psychological difficulties. The participants were a community sample of all students in two grades of regular school in a Swedish municipality who answered questionnaires as part of a two-wave longitudinal study with a one-year interval. The participants were 13-15 years old, and there were longitudinal data on 893 students, which represented 85% of all students. The cross-sectional associations were primarily tested by semi-partial correlations, and the longitudinal associations by hierarchical multiple regression. The results corroborated the meaningfulness of differentiating not only between direct and indirect aggression but also between direct and indirect victimization. Boys reported being more victim to direct aggression, whereas girls reported being more victim to indirect aggression. Direct aggression predicted increased conduct problems in boys, whereas indirect aggression predicted increased conduct problems in girls, and conduct problems reciprocally predicted increased direct and indirect aggression. Indirect victimization showed prospective bidirectional associations with emotional symptoms and conduct problems, suggesting the potential development of vicious cycles of escalating problems in these areas. The present results indicate that direct and indirect aggression, as well as direct and indirect victimization, may have different roles in the development of psychological difficulties in young adolescents. Further, the demonstration of prospective bidirectional associations points to a possible mechanism for the development of psychological difficulties, that may be described in terms of dynamical systems theory. This has potential relevance both for the prevention and the treatment of psychopathology.

Exposure to community violence through witnessing or being directly victimized has been associated with conduct problems in a range of studies. However, the relationship between community violence exposure (CVE) and conduct problems has never been studied separately in healthy individuals and individuals with conduct disorder (CD). Therefore, it is not clear whether the association between CVE and conduct problems is due to confounding factors, because those with high conduct problems also tend to live in more violent neighborhoods, i.e., an ecological fallacy. Hence, the aim of the present study was: (1) to investigate whether the association between recent CVE and current conduct problems holds true for healthy controls as well as adolescents with a diagnosis of CD; (2) to examine whether the association is stable in both groups when including effects of aggression subtypes (proactive/reactive aggression), age, gender, site and socioeconomic status (SES); and (3) to test whether proactive or reactive aggression mediate the link between CVE and conduct problems. Data from 1178 children and adolescents (62% female; 44% CD) aged between 9 years and 18 years from seven European countries were analyzed. Conduct problems were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia diagnostic interview. Information about CVE and aggression subtypes was obtained using self-report questionnaires (Social and Health Assessment and Reactive-Proactive aggression Questionnaire (RPQ), respectively). The association between witnessing community violence and conduct problems was significant in both groups (adolescents with CD and healthy controls). The association was also stable after examining the mediating effects of aggression subtypes while including moderating effects of age, gender and SES and controlling for effects of site in both groups. There were no clear differences between the groups in the strength of the association between witnessing violence and conduct problems. However, we found evidence for a ceiling effect, i.e., individuals with very high levels of conduct problems could not show a further increase if exposed to CVE and vice versa. Results indicate that there was no evidence for an ecological fallacy being the primary cause of the association, i.e., CVE must be considered a valid risk factor in the etiology of CD.

Data in gender differences in aggression among alcohol and drug dependent subjects are lacking, and no published data are available about gender differences among various subtypes of substance using populations. The goal of this cross-sectional study was to investigate gender differences with regard to types of trait aggression in substance dependent young populations (age: 20-35 years) compared to the general population. Subjects were selected from two clinical samples with a diagnosis of alcohol and drug dependence as well as from a representative sample of the general population. Trait aggression was measured by the four individual subscales of the Buss Perry Aggression Questionnaire (physical-PA, verbal aggression-VA, hostility-H and anger AN) whereas alcohol and drug use were characterized by the AUDIT and EuroADAD scales, respectively. Alcohol and drug dependent subjects showed higher severity on all four subscales of trait aggression compared to the general population. The male-female difference was the highest in the cannabis group. General Linear Model analysis for PA indicated a significant main effect of gender (higher PA for males, p=0.034) with no interaction between substance dependence and gender. For VA, no main effect or interaction for gender was found. Effect sizes for gender difference indicated that while males and females were similar in the control group in the severity in H and A, the level of H and AN was substantially higher in females than in males in the clinical group. These differences between the two genders reached statistical significance in the marijuana group, where female subjects showed a significantly higher severity in these two domains. Compared to the normal sample chronic substance use is associated with higher scores on certain factors of trait aggression, including hostility and anger, in females than in males. Our data suggest that aggression in substance dependent females is more provocable by chronic use of alcohol and drugs than in males. Copyright © 2011 Elsevier Inc. All rights reserved.

Background Associations between carotenoid intake and prostate cancer (CaP) incidence have varied across studies. This may be due to combining indolent with aggressive disease in most studies. This study examined whether carotenoid intake and adipose tissue carotenoid levels were inversely associated with CaP aggressiveness. Methods Data on African-American (AA, n=1,023) and European-American (EA, n=1,079) men with incident CaP from North Carolina and Louisiana were analyzed. Dietary carotenoid intake was assessed using a detailed food frequency questionnaire, and abdominal adipose tissue samples were analyzed for carotenoid concentrations using high-performance liquid chromatography. Multivariable logistic regression was used in race-stratified analysis to calculate odds ratios (ORs) and 95% confidence intervals (95%CI) comparing high aggressive CaP with low/intermediate aggressive CaP. Results Carotenoid intake differed significantly between AAs and EAs, which included higher intake of lycopene among EAs and higher β–cryptoxanthin intake among AAs. Comparing the highest and lowest tertiles, dietary lycopene was associated inversely with high aggressive CaP among EAs (OR=0.55, 95%CI: 0.34–0.89, Ptrend=0.02), while an inverse association was observed between dietary β–cryptoxanthin intake and high aggressive CaP among AAs (OR=0.56, 95%CI: 0.36–0.87, Ptrend=0.01). Adipose tissue α–carotene and lycopene (cis + trans) concentrations were higher among EAs than AAs, and marginally significant inverse linear trends were observed for adipose α–carotene (Ptrend=0.07) and lycopene (Ptrend=0.11), and CaP aggressiveness among EAs only. Conclusions These results suggest that diets high in lycopene and β–cryptoxanthin may protect against aggressive CaP among EAs and AAs, respectively. Differences in dietary behaviors may explain the racial differences in associations. PMID:27271547

Evaluation of aggression in Australian after-hours doctor home-visit services.

2018-04-01

Minimizing the risks and distress arising from aggression in after-hours house call (AHHC) services will help improve service quality in the industry. Unfortunately, no national study has ever evaluated this in Australian AHHCs. Apart from reducing this gap, findings from this work will have global relevance given the rising popularity of the AHHC industry worldwide. A survey of all 300 doctors employed by the National Home Doctor Service, Australia's largest AHHC service provider. A validated electronic questionnaire was used to examine the doctors' experiences over a 12-month period. There were 168 valid responses (56% response rate). Aggression prevalence was 47.1%, and just over half (51.8%) of the cases came from the patients. "Verbal aggression" was the commonest (48.3%). Others are "threats" (26.6%), "vexatious complaints" (13.3%), "property damage" (4.2%), "physical violence" (4.2%), "sexual harassment" (2.8%), and "stalking" (0.7%). Majority of the respondents were concerned (90.2%) and apprehensive (75.2%) regarding the risks. Doctors who have experienced aggression were more likely to express apprehension (OR = 3.99; CI = 1.54-10.31; P = 0.004), while those that have attained Postgraduate Fellowships (Vocationally Registered) were less likely to report experiences of aggression (OR = 0.28; CI = 0.09-0.84; P = 0.02). Even though a higher proportion of females were concerned (92.3% vs 89.6%) and apprehensive (82.1% vs 73.6%) compared with males, these differences were not statistically significant (Fisher's Exact Tests: P = 1.000 and 0.469, respectively). Aggression in Australian AHHC affects nearly 1-in-2 practitioners, with high levels of concern and apprehension being expressed. Concerned companies should do more to ensure that their doctors attain PG fellowships, as this is linked to lower reports of aggression. Where possible, family and friends need to be involved in patient care, as nearly half of the reported aggressions come from them. © 2017 John Wiley & Sons, Ltd.

The aim of this research is to look into the roles of families' social situation and cohesion in adolescent auto-aggressiveness in Croatia. The research was conducted on a sample of Zagreb high school students which encompassed 701 pupils of both genders aged 14-19. The basic demographic data were obtained using the Structured Demographic and Family Data Questionnaire. Auto-aggressiveness was tested using a section of the Report on Youth Aged 11-18 and the Scale of Auto-destructiveness--SAD, whereas the family cohesion was tested with the Family Adaptability and Cohesion Evaluation Scales FACES III. The obtained results show differences according to the gender: girls are more prone to auto-aggressiveness than boys (t = -3.385, df = 565, p = 0.001) and girls more often show symptoms of destructiveness (t = -3.809, df = 637, p < 0.001) and anxiety (t = -6.562, df = 640, p < 0.001), while boys show pronounced aggressiveness (t = 2.655, df = 653, p = 0.008). Significant family factors associated with auto-aggressiveness are parents' marital status (chi2 = 18.039, df = 4, p = 0.001), their financial situation (F(2.548) = 4.604, p = 0.010), alcoholic father (chi2 = 9.270, df = 2, p = 0.010), mentally ill mother (t = 5.264, df = 541, p < 0.001), as well as mentally ill father (t = 4.744, df = 529, p < 0.001), and corporal punishment by mother (F(2.542) = 8.132, p < 0.001) or father (F(2.530) = 5.341, p = 0.005). Adolescents from split families show more auto-aggressiveness. Family cohesion appears to be considerably associated with auto-aggressiveness and the adolescents that see their families as less cohesive have more mental problems (chi2 = 29.98, df = 2, p < 0.001). There is a connection between auto-destructive behavior in adolescents and family factors. Knowledge of family's social situation and cohesion may help understand, prevent and treat auto-aggressiveness in adolescents.

The aims of this study were (1) to examine differences in the level of self-esteem among adolescents with different roles in aggression involvement (aggression perpetrators, victims, perpetrator-victims and neutrals) according to gender and (2) to examine the moderating effects of depression and family support on association between aggression involvement and self-esteem. A total of 8085 adolescents in Taiwan completed questionnaires. The relationships between self-esteem and aggression involvement were examined by multiple regression analysis. The moderating effects of depression and family support on the association between aggression involvement and self-esteem were examined. The results showed that in females, aggression victims had lower self-esteem than those in the other three groups (t=-2.940 to 2.173, p<0.05); however, there was no significant difference in self-esteem among perpetrators, perpetrator-victims, and neutrals (t=0.693-0.933, p>0.05). In males, self-esteem in victims and perpetrator-victims was lower than in neutrals and perpetrators (t=-3.339 to -2.704, p<0.01); however, there was no difference in self-esteem between victims and perpetrator-victims (t=-1.115, p>0.05) or between perpetrators and neutrals (t=-1.396, p>0.05). Family support had a moderating effect on the association between self-esteem and victimization in males. Depression had a moderating effect on the association between self-esteem and perpetration-victimization and victimization in males. The results indicate that self-esteem in adolescents with different patterns of involvement in aggression is not the same as in those without involvement. The moderating effects of depression and family support should be considered when developing intervention strategies to raise self-esteem in adolescents with aggression involvement. Copyright © 2012.

Background. Nowadays, one sixth of the world's population is represented by adolescents, nearly 1.2 billion people being of age 10-19. According to the 2011 census in Iran, the estimation of adolescent population was 12 million, which represents 16% of the Iran population. Undoubtedly, adolescence is the most dominant stage of life. During this period, adolescents face biological, cognitive, and emotional changes that may be accompanied by inappropriate behavioral responses such as aggression. Considering pressures of peer groups during adolescence, assertiveness has an important role as a social skill. It seems that the success of adolescents in dealing with these problems depends on their self-efficacy. This study was designed to explore the role of self-efficacy and assertiveness in aggression among high-school students. Material and methods. This cross-sectional and correlational study was conducted among 321 first grade high-school students during 2014 and 2015. Samples were extracted from six education and training regions by a multi-stage random sampling. In this study, the questionnaire included demographic, Rathus Assertiveness, self-efficacy for children and aggression data. Results. The results showed that there was a notable negative association between aggression and assertiveness (p < 0.003) and also between assault and self-efficacy (p < 0.001). Conclusions. An increase in assertiveness and self-efficacy resulted in a decrease of aggression. So, training was recommended to reinforce self-efficacy beliefs and assertiveness behaviors for mental health promotion.

Workplace aggression remains an important source of distress among nurses and midwives and has negative effects on staff health, patient care and organisations' reputation and fiscal health. To report on the nature and extent of workplace aggression, including bullying experienced by nurses and midwives in Victoria, Australia. A descriptive study design was chosen. The Nurses Board of Victoria posted 5000 surveys to the randomly selected registered nurses and midwives in Victoria, Australia, in 2010. The participants were asked about their experiences of violence (from clients) and bullying (from colleagues) within their most recent four working weeks. In addition, the study investigated staff actions following incidents, staff training and safety at work, and what staff believe contribute to incidents. Data analysis involved descriptive statistics, including frequencies and percentages. Chi square tests and P value were used to assess differences in categorical data. 1495 returned questionnaires were included in the study (30% response rate). Over half of the participants (52%) experienced some form of workplace aggression. Thirty-six percent experienced violence mostly from patients or their visitors/relatives and 32% experienced bullying mostly from colleagues or from their managers/supervisors. Significant differences were found between those who experienced aggression from patients and those who were bullied in respect to handling of incidents; factors thought to contribute to incidents; and organisations' handling of incidents. The study suggests that staff are less worried by patient initiated aggression compared to bullying from colleagues. For all types of aggression, respondents clearly wanted better/more realistic training, as well as enforcement of policies and support when incidents arise. Copyright © 2012 Elsevier Ltd.

Early life stress has been shown to contribute to alterations in biobehavioral regulation. Whereas many different forms of childhood adversities have been studied in relation to cardiovascular outcomes, very little is known about potential associations between caregivers' verbally aggressive behavior and heart rate and blood pressure in the child. This prospective study examined whether maternal verbally aggressive behavior in early infancy is associated with heart rate or blood pressure at age 5-6. In the Amsterdam Born Children and their Development study, a large prospective, population-based birth cohort, maternal verbally aggressive behavior was assessed by questionnaire in the 13th week after birth. The child's blood pressure and heart rate were measured during rest at age 5-6 (n=2553 included). Maternal verbally aggressive behavior in infancy was associated with a higher systolic blood pressure (SBP) both in supine and sitting position after adjustment for sex, height and age (SBP supine B=1.01 mmHg; 95% CI [0.06; 1.95] and SPB sitting B=1.29 mmHg; 95% CI [0.12; 2.46]). Adjustment for potential confounding variables, such as other mother-infant dyad aspects, family hypertension and child's BMI, only slightly attenuated the associations (SBP supine B=0.99 mmHg; 95% CI [0.06; 1.93] and SPB sitting B=1.11 mmHg; 95% CI [-0.06; 2.27]). Maternal verbally aggressive behavior was not associated with diastolic blood pressure or heart rate at age 5-6. Maternal verbally aggressive behavior might be an important early life stressor with negative impact on blood pressure later in life, which should be further investigated. Possible underlying mechanisms are discussed.

"Latent" infection with Toxoplasma gondii: association with trait aggression and impulsivity in healthy adults.

Latent chronic infection with Toxoplasma gondii (T. gondii), a common neurotropic pathogen, has been previously linked with suicidal self-directed violence (SSDV). We sought to determine if latent infection with T. gondii is associated with trait aggression and impulsivity, intermediate phenotypes for suicidal behavior, in psychiatrically healthy adults. Traits of aggression and impulsivity were analyzed in relationship to IgG antibody seropositivity for T. gondii and two other latent neurotropic infections, herpes simplex virus 1 (HSV1) and cytomegalovirus (CMV). One thousand community-residing adults residing in the Munich metropolitan area with no Axis I or II conditions by SCID for DSM-IV (510 men, 490 women, mean age 53.6 ± 15.8, range 20-74). Plasma samples were tested for IgG antibodies to T. gondii, HSV-1 and CMV by ELISA. Self-reported ratings of trait aggression scores (Questionnaire for Measuring Factors of Aggression [FAF]) and trait impulsivity (Sensation-Seeking Scale-V [SSS-V]) were analyzed using linear multivariate methods. T. gondii IgG seropositivity was significantly associated with higher trait reactive aggression scores among women (p < .01), but not among men. T. gondii-positivity was also associated with higher impulsive sensation-seeking (SSS-V Disinhibition) among younger men (p < .01) aged 20-59 years old (median age = 60). All associations with HSV-1 and CMV were not significant. Aggression and impulsivity, personality traits considered as endophenotypes for SSDV, are associated with latent T. gondii infection in a gender and age-specific manner, and could be further investigated as prognostic and treatment targets in T. gondii-positive individuals at risk for SSDV.

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. 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. 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. 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. 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.

To determine whether our health care employees were undergoing mammography screening according to American Cancer Society guidelines and to determine whether aggressive outreach, education and streamlining of mammography scheduling could improve compliance. All female employees at North Shore University Hospital (NSUH) and several other health system facilities (SF) were sent mailings to their homes that included breast health education and mammography screening guidelines, a questionnaire regarding their own mammography screening history and the opportunity to have their mammography screening scheduled by the Mammography Screening Employee Inreach Program (MSEIP) coordinator. Of the approximately 2,700 female employees aged 40 and over at NSUH and SF, 2,235 (82.7%) responded to the questionnaire, and 1,455 had a mammogram done via the MSEIP. Of the 1,455, 43% either were overdue for a mammogram or had never had one. During a second year of the MSEIP at NSUH and SF, an additional 1,706 mammograms were done. People employed in health care jobs do not necessarily avail themselves of appropriate health care screening. An aggressive program that utilized education, outreach and assistance with scheduling was effective in increasing compliance with mammography screening.

Children and adolescents facing a continuous security threat: Aggressive behavior and post-traumatic stress symptoms.

There is extensive research evidence indicating that children and youth are the most vulnerable population for developing psychological symptoms relating to war and terror. Although studies have documented a wide range of detrimental emotional and behavioral effects of such exposure, much less is known about the effects of exposure to a continuous security threat for children and adolescents. Against this background, the current article examined the implications of continuous exposure to missile attacks among 1096 children and adolescents enrolled in public schools near the Israeli border with Gaza. Participants filled out quantitative questionnaires, which relate to the pathological consequences of continuous exposure to security threats, and to the role of the school and the community as a protective environment against disruptive behavior resulting from such exposure. The findings revealed that PTSS responses were mainly related to the security threat, whereas interpersonal aggression resulted from other types of traumatic events. Significant differences were found between aggression and posttraumatic symptoms, by age and gender. PTSS was found to be lower for older participants and higher for girls, whereas aggression was higher for boys and higher for older participants. Furthermore, the sense of belonging to the place of residence was negatively associated with PTSS as well as with aggressive behavior: the higher the participants' sense of belonging, the lower their levels of PTSS and aggressive responses. In contrast, the sense of belonging to the school was negatively associated only with aggressive behavior: the higher the participants' sense of belonging to the school, the lower their aggressive responses. The findings are discussed in the light of trauma theories and in light of the results of previous research. The study contributed to knowledge about the differential consequences of exposure to a security threat, and highlighted the importance of differential interventions with children who show post-traumatic symptoms versus those who show aggressive behavior. Accordingly, the security situation should not overshadow social issues that need to be addressed, such as family violence and aggression among school children. Copyright © 2017 Elsevier Ltd.

Patients' irritability and aggression have been linked to caregiver depression, but the behaviors that most burden caregivers are not yet definitively identified. This study examines the connection between behavioral and psychological symptoms of dementia (BPSD) and the burnout of caregivers caring for home-dwelling elders with dementia symptoms in Japan. 80 Japanese rural and urban family caregivers completed detailed questionnaires about their experiences in caring for demented family members. We statistically analyzed the results for correlations between types of dementia, Pines Burnout, and Caregiver Distress. BPSD symptom severity significantly correlated with caregiver distress. The dementia symptoms most strongly correlated with caregiver burnout were: aggression, irritability, abnormal motor behavior, and hallucinations. Among the commonest symptoms, apathy, anxiety, and depression did not seriously aggravate caregiver burnout. Caregivers displayed higher burnout facing agitation/aggression, irritability, aberrant motor behavior, and hallucinations. Caregivers' reported distress was surprisingly dissimilar to their burnout scores; patients' delusions and anxiety led to higher distress reporting but not to burnout. Advance diagnosis of BPSD symptoms should be helpful to support nurses and caregivers of dementia patients. Particular support should be considered for caregivers and nurses of patients expressing aggression, irritability, abnormal motor behavior, and hallucination.

The relationships between social goals, skills, and strategies and their effect on aggressive behavior among adolescents.

It is widely accepted that conflict-related goals, skills, and strategies are linked. Yet it is rarely explored how these factors relate to each other and how they jointly promote or inhibit aggressive behaviors. The aim of this study is to provide answers to these questions. Data were derived from a structured questionnaire administered to 660 male and female adolescents of an average age of 14.99 years from two urban schools in northern Israel. Findings show that goals, skills, and strategies that promote or inhibit violence are positively interrelated. Furthermore, negative association was found between violence promoting and inhibiting goals, skills, and strategies. Gender differences were also analyzed. It has been found that boys display aggressive behavior more frequently then girls. Findings also show that the rate of violence promoting goals, skills, and strategies is higher among boys than among girls, whereas that of violence inhibiting ones are higher among girls than among boys. Yet when controlling the effects of goals, skills, and strategies, girls demonstrate aggressive behavior more frequently than boys. These research findings are discussed and conceptualized within the theoretical framework of social adjustment.

The purpose of this cross-sectional study was to investigate the effect of different forms of periodontal diseases on Oral Health-Related Quality of Life (OHRQoL). Fifty-two patients with Aggressive Periodontitis (AP) or Chronic Periodontitis (CP) were included: nine patients with Localized Aggressive Periodontitis (LAP), thirty-three patients with Generalized Aggressive Periodontitis (GAP) and ten patients with Generalized Chronic Periodontitis (GCP). Oral Health Impact Profile questionnaires (OHIP-14) were distributed after a clinical examination that measured the following periodontal parameters: tooth loss, bleeding on probing (BoP), probing depth (PD), gingival recession (REC) and clinical attachment level (CAL). The global OHIP-14 score means were 10.6 for LAP, 16.5 for GAP, and 17.5 for GCP. A statistically significant difference (p < 0.01) was observed between the LAP group and the other two groups. There was significantly less bleeding and recession in the LAP group than in the patients with the generalized forms of periodontitis. LAP, GAP and GCP have an impact on patient quality of life when measured using the OHIP-14. Patients with GAP and GCP had poorer OHRQoL than LAP patients.

Intimate Partner Violence Victimization in the Cyber and Real World: Examining the Extent of Cyber Aggression Experiences and Its Association With In-Person Dating Violence.

2018-04-01

This study explores the extent of cyber aggression victimization in intimate relationships and its co-occurrence with in-person experiences of psychological, physical, and sexual partner violence. Data were collected from 540 college students who reported being in a dating relationship in the past 12 months. Participants were asked to complete an online questionnaire that included measures assessing intimate partner victimization experiences in differing social contexts (through socially interactive technology and in face-to-face encounters). Findings indicated that intimate partner cyber aggression victimization is not uncommon, as nearly three quarters of respondents reported having experienced some form of it in the past year. Multivariate analyses also indicate that such aggression may be part of a larger violence nexus given its relation to in-person psychological, physical, and sexual partner violence victimization experiences. In light of these findings, it is recommended that longitudinal research encompassing multiple violence victimization experiences in varying social contexts is completed to determine whether online experiences foreshadow offline ones and, if so, consider interaction effects on outcomes as well as potential intervention strategies to reduce harm associated with such negative experiences.

The study takes a detailed look at psychiatric patient violence towards their psychiatrists. It takes into consideration the views and opinions of Italian psychiatrists, whether they have experienced violent behaviour first hand and, if so, which type of aggression and whether this caused them to modify their behaviour towards the patient and his or her treatment. A multiple-choice questionnaire is sent to all members of the Italian Society of Psychiatry, with 1,202 psychiatrists responding (20.23% of the sample). The data are evaluated using SPSS with chi-square test calculations for discrete and continuous variables and t-testing for independent samples (significance p < .05). Almost all psychiatrists (90.9%) have experienced verbal aggression; 72% have been threatened with dangerous objects and 64.58% have suffered physical aggression. Physical aggression experiences result in a 50% increase in the probability of modifying one's therapeutic behaviour. Significant differences emerge between the psychiatrists, according to differences in age and career experience. Psychiatrists state that they do not consider themselves to be adequately prepared to deal with the violence of patients, and almost all psychiatrists felt the need for specific training in how to manage such violence.

Dormant Masculinity: Moderating Effects of Acute Alcohol Intoxication on the Relation Between Male Role Norms and Antigay Aggression

2014-01-01

Acute alcohol intoxication was examined as a moderator of the association between men’s adherence to traditional gender norms and aggression towards a gay male. Participants were 164 heterosexual drinking men between the ages of 21–30. Participants completed a battery of questionnaires that included a measure of adherence to male role norms (i.e., status, toughness, antifemininity), were randomly assigned to consume an alcohol or no-alcohol control beverage, and completed the Taylor Aggression Paradigm in which electric shocks were administered to, and received from, a fictitious gay or heterosexual male opponent. Results indicated a greater adherence to both the toughness (β = .50, p = .002) and antifeminine (β = .37, p = .023) norms predicted high levels of aggression towards a gay man only among participants who were intoxicated. This interaction effect was not detected for the status norm. Consistent with previous research, findings suggest that adherence to the toughness norm does not increase sober men’s risk of aggression toward gay men. However, this is the first study to demonstrate that alcohol intoxication may activate concepts of toughness, and thus influence men to act in line with this facet of the masculine concept. Importantly, these data support the view that men’s adherence to various dimensions of masculinity may be dormant in some contexts, only to be activated, and subsequently demonstrated, in other contexts.

Objective Although research has established childhood sexual abuse (CSA) as a risk factor for men’s perpetration of sexual aggression, there has been little investigation of the factors undergirding this association. This study represents one of the first to use a laboratory-based sexual aggression analogue coupled with an alcohol administration protocol to investigate the pathways through which CSA and alcohol influence men’s self-reported sexual aggression intentions. Method After completing background questionnaires, male social drinkers (N = 220) were randomly assigned to a control, placebo, low alcohol dose or high alcohol dose condition. Following beverage consumption, participants read a sexual scenario in which the female partner refused to have unprotected sexual intercourse, after which they completed dependent measures. Results Path analysis indicated that men with a CSA history and intoxicated men perceived the female character as more sexually aroused and reported stronger sexual entitlement cognitions, both of which were in turn associated with greater condom use resistance and higher sexual aggression intentions. Exploratory analyses revealed that intoxication moderated the effects of CSA history on sexual entitlement cognitions, such that sexual entitlement cognitions were highest for men who had a CSA history and consumed alcohol. Conclusions Findings suggest that CSA history may facilitate sexual assault perpetration through its effects on in-the-moment cognitions, and that these effects may be exacerbated by alcohol intoxication.

Patient initiated aggression is common among Chinese health-care workers, reaching over 10,000 incidents annually (Jinyang web. http://6d.dxy.cn/article/55497 . 2013), and the tense doctor-patient relationship generates stress among medical students. Because of the paucity of data (few surveys pay attention to the effects of violence perpetrated by patients on medical students), this study aimed to characterize patient initiated aggression against medical students. In this cross-sectional survey conducted at a medical school in West China in 2015, 157 medical students completed a self-administered questionnaire and the Short Form-36, which assesses quality of life. The associations between patient initiated aggression exposure and medical students' career planning or quality of life were assessed using a chi-square test. Of the 157 medical students, 48 (30.6%) reported having suffered patient initiated aggression at least once during the previous year in the form of mental abuse (20.4%), offensive threat (14.6%), physical violence (8.3%), sexual harassment (verbal: 8.3% or physical: 1.6%), and extreme violence (physical violence leading to surgical treatment or hospitalization) (0.6%). Insufficient communication was the primary reason cited (27.2%). Emotional attack (mental abuse and offensive threat) occurrence differed among age groups (χ 2  = 9.786, P = 0.020) and was ubiquitous among those aged >30 years old. Women were more likely than men to suffer physical violence (χ 2  = 6.796, P = 0.009). Patient initiated aggression was not significantly associated with medical students' career planning or quality of life. In this study, patient initiated aggression, albeit common, as in the rest of China, did not appear to be associated with medical students' career planning or quality of life. However, the characteristics described can inform policymaking and the design of programs to minimize patient initiated aggression occurrence.

2018-04-01

In substance use and psychotic disorders, socially problematic behaviours, such as high aggression may, in part, be explained by deficits in social cognition skills, like the detection of emotions or intentions in others. The aim of this study was to assess the magnitude of social cognition impairment and its association with aggression in individuals with methamphetamine (MA) dependence, methamphetamine-associated psychosis (MAP), and healthy controls (CTRL). A total of 20 MAP participants, 21 MA-dependent participants without psychosis, and 21 CTRL participants performed a facial morphing emotion recognition task (ERT) across four basic emotions (anger, fear, happiness and sadness) and the reading the mind in the eyes task (RMET), and completed the aggression questionnaire. Both MA-dependent groups showed impairment in social cognition in terms of lower RMET scores relative to CTRL participants (MA; p = .047; MAP: p < .001). Additionally, performance decrements were significantly greater in MAP (p = .040), compared to MA-dependent participants. While deficits in recognising emotional expressions were restricted to anger in the MA group (p = .020), a generalized impairment across all four emotions was observed in MAP (all p ≤ .001). Additionally, both patient groups demonstrated higher levels of aggression than CTRLs, yet no association was found with social cognition. This study supported the notion of deficits in recognising facial emotional expressions and inferring mental states of others in MA dependence, with additional impairments in MAP. Failure to detect an association between social cognitive impairment and aggressive behaviour may implicate independent disturbances of the two phenomena in MA dependence.

The use of information and communication technologies has become ubiquitous among adolescents. New forms of cyber aggression have emerged, cybergrooming is one of them. However, little is known about the nature and extent of cybergrooming. The purpose of this study was to investigate risk factors of being cybergroomed, to identify various coping strategies and to explore the associations between being cyberbullied and cybergroomed. The sample consisted of 518 students in 6th to 10th grades. The computer assisted personal interview method (CAPI method) was implemented. The «Mobbing Questionnaire for Students» by Jäger et al. (2007) was further developed for this study and served as the research instrument. While being a girl, being cyberbullied and willingness to meet strangers could be identified as risk factors; no significant age differences were found. Furthermore, three types of coping strategies - aggressive, cognitive-technical and helpless - with varied impacts were identified. The findings not only shed light on understanding cybergrooming, but also suggest worth noting associations between various forms of cyber aggression.

Background There is emerging evidence that the supplementation of omega-3 contributes to a decrease in aggressive behaviour in prison populations. A challenge of such research is achieving statistical power against effect sizes which may be affected by the baseline omega-3 index. There are no published data on the blood omega-3 index with studies of this kind to assess the variability of the blood omega-3 index in conjunction with aggression and attention deficit assessments. Objective To determine if the variance of the omega-3 index is correlated with aggressive and attention deficit behaviour in a prison population. Design 136 adult male prisoners were recruited from South Coast Correctional Centre (SCCC), NSW Australia. A 7 point categorisation was used to quantify levels of aggressive behaviour (4 weeks) from individual SCCC case notes, whereby higher scores correspond to increasingly aggressive behaviour. Study participants completed the Aggression Questionnaire (AQ) and the Brown’s Attention Deficit Disorder Scales (BADDS), provided a blood sample for erythrocyte fatty acid analysis using gas chromatography and the omega-3 index was calculated. Results The baseline omega-3 index ranged from 2.3% to 10.3%, indicating that some participants already had substantial omega-3 intake, however a median of 4.7% indicated a lower overall omega-3 intake than the general Australian population. Assessment of aggressive and attention deficit behaviour shows that there were negative correlations between baseline omega-3 index and baseline aggression categorisation scores (r = −0.21, P = 0.016); total AQ score (r = −0.234, P = 0.011); Anger (r = -0.222 p = 0.016); Hostility AQ (r = −0.239, P = 0.009); indirect aggression (r = −0.188 p = 0.042); total BADDS (r = −0.263, p = 0.005); Activation (r = −0.224, p = 0.016); Attention (r = −0.192, p = 0.043); Effort (r = −0.253, p = 0.007); Affect (r = −0.330, p = 0.000) and Memory (r = −0.240, p = 0.010). Conclusions There is a high variability in omega-3 status of a NSW prison population, and inmates with lower omega-3 index were more aggressive and had higher ADD scores. PMID:25793501

Experience-based human perception of facial expressions in Barbary macaques (Macaca sylvanus).

Maréchal, Laëtitia; Levy, Xandria; Meints, Kerstin; Majolo, Bonaventura

2017-01-01

Facial expressions convey key cues of human emotions, and may also be important for interspecies interactions. The universality hypothesis suggests that six basic emotions (anger, disgust, fear, happiness, sadness, and surprise) should be expressed by similar facial expressions in close phylogenetic species such as humans and nonhuman primates. However, some facial expressions have been shown to differ in meaning between humans and nonhuman primates like macaques. This ambiguity in signalling emotion can lead to an increased risk of aggression and injuries for both humans and animals. This raises serious concerns for activities such as wildlife tourism where humans closely interact with wild animals. Understanding what factors (i.e., experience and type of emotion) affect ability to recognise emotional state of nonhuman primates, based on their facial expressions, can enable us to test the validity of the universality hypothesis, as well as reduce the risk of aggression and potential injuries in wildlife tourism. The present study investigated whether different levels of experience of Barbary macaques, Macaca sylvanus , affect the ability to correctly assess different facial expressions related to aggressive, distressed, friendly or neutral states, using an online questionnaire. Participants' level of experience was defined as either: (1) naïve: never worked with nonhuman primates and never or rarely encountered live Barbary macaques; (2) exposed: shown pictures of the different Barbary macaques' facial expressions along with the description and the corresponding emotion prior to undertaking the questionnaire; (3) expert: worked with Barbary macaques for at least two months. Experience with Barbary macaques was associated with better performance in judging their emotional state. Simple exposure to pictures of macaques' facial expressions improved the ability of inexperienced participants to better discriminate neutral and distressed faces, and a trend was found for aggressive faces. However, these participants, even when previously exposed to pictures, had difficulties in recognising aggressive, distressed and friendly faces above chance level. These results do not support the universality hypothesis as exposed and naïve participants had difficulties in correctly identifying aggressive, distressed and friendly faces. Exposure to facial expressions improved their correct recognition. In addition, the findings suggest that providing simple exposure to 2D pictures (for example, information signs explaining animals' facial signalling in zoos or animal parks) is not a sufficient educational tool to reduce tourists' misinterpretations of macaque emotion. Additional measures, such as keeping a safe distance between tourists and wild animals, as well as reinforcing learning via videos or supervised visits led by expert guides, could reduce such issues and improve both animal welfare and tourist experience.

Associations between carotenoid intake and prostate cancer (CaP) incidence have varied across studies. This may result from combining indolent with aggressive disease in most studies. This study examined whether carotenoid intake and adipose tissue carotenoid levels were inversely associated with CaP aggressiveness. Data on African-American (AA, n = 1,023) and European-American (EA, n = 1,079) men with incident CaP from North Carolina and Louisiana were analyzed. Dietary carotenoid intake was assessed using a detailed-food frequency questionnaire (FFQ), and abdominal adipose tissue samples were analyzed for carotenoid concentrations using high-performance liquid chromatography. Multivariable logistic regression was used in race-stratified analyses to calculate odds ratios (ORs) and 95% confidence intervals (95%CI) comparing high aggressive CaP with low/intermediate aggressive CaP. Carotenoid intake differed significantly between AAs and EAs, which included higher intake of lycopene among EAs and higher β-cryptoxanthin intake among AAs. Comparing the highest and lowest tertiles, dietary lycopene was associated inversely with high aggressive CaP among EAs (OR = 0.55, 95%CI: 0.34-0.89, Ptrend  = 0.02), while an inverse association was observed between dietary β-cryptoxanthin intake and high aggressive CaP among AAs (OR = 0.56, 95%CI: 0.36-0.87, Ptrend  = 0.01). Adipose tissue α-carotene and lycopene (cis + trans) concentrations were higher among EAs than AAs, and marginally significant inverse linear trends were observed for adipose α-carotene (Ptrend  = 0.07) and lycopene (Ptrend  = 0.11), and CaP aggressiveness among EAs only. These results suggest that diets high in lycopene and β-cryptoxanthin may protect against aggressive CaP among EAs and AAs, respectively. Differences in dietary behaviors may explain the observed racial differences in associations. Prostate 76:1053-1066, 2016. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

We have analysed the MAOA-uVNTR polymorphism in the promoter region of the X-chromosomal monoamine oxidase A (MAOA) gene. The first aim was to examine the association between the MAOA genotype and the alcoholic phenotype. In the second part of the paper we have analysed the association of the MAOA genotype with impulsive and aggressive behaviour. Genotypes with 3 or 5-repeat alleles (MAOA-L-genotype) were reported to be associated with impulsive and aggressive traits. The MAOA genotype was determined in 371 male alcohol-dependent subjects and 236 male controls all of German descent. Behavioural and personality traits were evaluated using the self-report questionnaires Barratt Impulsiveness Scale (BIS), Buss Durkee Hostility Inventory (BDHI), Temperament and Character Inventory (TCI) and NEO-Five Factor Inventory (NEO-FFI). A median split in BIS, Buss Durkee Physical Assault, Buss Durkee Irritability, TCI and NEO-FFI was conducted. No association could be detected between the MAOA genotype and the alcoholic phenotype. Based on the results of the BIS questionnaire, we were able to make out an association between the MAOA-L genotype and higher levels of impulsivity (p = 0.043). Furthermore - without reaching statistical significance - we detected a very slight association between the MAOA-L genotype and higher scores in the BDHI subcategory physical aggression (p = 0.058). Taken together, these findings suggest that the MAOA-L genotype is to some extent associated with impulsive and antisocial personality traits in alcoholic men. Further studies on that question are needed. © Georg Thieme Verlag KG Stuttgart · New York.

Promoting prosocial pupil behaviour: 2-secondary school intervention and pupil effects.

Mooij, T

1999-12-01

In an earlier article (Mooij, 1999c) a theoretical multilevel model to promote prosocial pupil behaviour by stimulating specific educational conditions was developed. To carry out school interventions to check empirically whether pupil level effects occur because of educational changes at the classroom and school level. Seven secondary schools with relatively high degrees of pupil aggression were selected. Four schools took part as intervention schools, three schools served as control schools. In 1995 (pretest) and 1997 (post-test) pupils and form teachers of the first and third school years participated by completing questionnaires. Within the pupil cohorts, a longitudinal group of 352 pupils was included. Pretest questionnaires in 1995 were followed by intervention in the intervention schools. Teachers collaborated with staff and researchers to increase pupils' participation and responsibility in specifying and controlling behavioural and didactic rules, related to didactic differentiation during lessons. The validity of the intervention implementation was checked using qualitative information and quantitative data from both pre- and post-test. Longitudinal intervention effects were tested by applying two-level multiple regression analyses. After controlling for pretest and covariables in school year 1, school intervention effects were found in school year 3 with the prediction of being a perpetrator of aggressive behaviour at school, aggressive behaviour outside school, and criminal behaviour. Some small effects were found with respect to victim behaviour. Social-pedagogical and didactic class and school variables, but also home variables and support by peers without problematic behaviour, could be integrated more systematically to promote prosocial development of a pupil's behaviour from the beginning in school.

Background: The Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) was developed in an attempt to define the basic factors of personality or temperament. We aimed to assess the factor structure and the psychometric properties of its Greek version and to explore its relation to psychopathological symptoms and hostility features. Methods: ZKPQ was translated into Greek using back-translation and was administered to 1,462 participants (475 healthy participants, 619 medical patients, 177 psychiatric patients and 191 opiate addicts). Confirmatory and exploratory factor analyses were performed. Symptoms Distress Check-List (SCL-90R) and Hostility and Direction of Hostility Questionnaire (HDHQ) were administered to test criterion validity. Results: Five factors were identified, largely corresponding to the original version’s respective factors. Retest reliabilities were acceptable (rli’s: 0.79-0.89) and internal consistency was adequate for Neuroticism-Anxiety (0.87), Impulsive Sensation Seeking (0.80), Aggression-Hostility (0.77) and Activity (0.72), and lower for Sociability (0.64). Most components were able to discriminate psychiatric patients and opiate addicts from healthy participants. Opiate addicts exhibited higher rates on Impulsive Sensation Seeking compared to healthy participants. Neuroticism-Anxiety (p<0.001) and Impulsive Sensation Seeking (p<0.001) were significantly associated with psychological distress and Aggression-Hostility was the most powerful correlate of Total Hostility (p<0.001), and Neuroticism-Anxiety was the stronger correlate of introverted hostility (p<0.001), further supporting the instrument’s concurrent validity. Conclusions: Present findings support the applicability of the Greek version of ZKPQ within the Greek population. Future studies could improve its psychometric properties by finding new items, especially for the Sociability scale. PMID:25031514

Barroom Aggression Among Australian Men: Associations With Heavy Episodic Drinking, Conformity to Masculine Norms, and Personal and Perceived Peer Approval of Barroom Aggression.

Research suggests that heavy episodic drinking (HED), perceived peer norms, and personal approval of aggression influence male barroom aggression (MBA). Qualitative research suggests that conformity to hegemonic masculine gender norms also influences MBA; however, quantitative research on the direct and indirect influence of masculinity on MBA is limited. This study tested the relationships between HED, conformity to masculine gender norms, and personal approval and peer approval of MBA on MBA perpetration, as well as the indirect effect of masculine norms on MBA via HED. A convenience sample of Australian men (N = 322; mean age = 21.05 years, SD = 1.95; 76.9% university students) completed an online questionnaire, assessing HED and MBA over the previous year, and subscales of the Beliefs and Attitudes Towards Male Alcohol-Related Aggression Inventory and Conformity to Masculine Norms Inventory-46. Negative binomial regression analyses found that, overall, HED, male peer approval, and personal approval of MBA directly predicted increased risk of verbal and physical MBA perpetration. Greater conformity to specific masculine norms also increased (Power Over Women) and decreased (Emotional Control, Heterosexual Self-Presentation) risk of MBA perpetration. The masculine norms Risk Taking, Playboy, and Emotional Control were found to be indirect predictors of MBA via HED. Risk of MBA perpetration is increased primarily by HED as a direct, but also mediating, predictor. Personal and male peer approval of MBA, and specific masculine norms, further increase this risk whereas other masculine norms appear protective.

Recent studies indicate that adipose tissue and adipocytokines might affect the development of prostate cancer (PCa). Leptin would have a stimulating effect on prostate cancer cells by inducing promotion and progression, whereas adiponectin would have a protective effect. The aim of this study was to determine the relation between body composition, leptin, and adiponectin levels with the prevalence and aggressiveness of PCa in men of Mendoza, Argentina. Seventy volunteers between 50 and 80 years (35 healthy men as control group and 35 with PCa) were selected. The PCa group was subclassified according to the Gleason Score (GS). Digital rectal examination, transrectal ultrasound, and prostatic biopsy were performed; PSA, testosterone, leptin, and adiponectin levels were determined; and a nutritional interview including anthropometric measurements and a food frequency questionnaire was carried out. Statistical analysis was performed by Student t test, ANOVA I, and Bonferroni (p < 0.05). Body mass index and percentage of body fat mass were not statistically different between PCa and control groups. However, body fat mass was higher in subjects with more aggressive tumors (p = 0.032). No differences were observed regarding leptin levels between the groups. Nevertheless, leptin levels were higher in subjects with high GS (p < 0.001). Adiponectin levels showed no statistical differences regarding the presence and aggressiveness of the tumor (p = 0.131). Finally, consumption and nutrient intake did not differ in the studied groups. In conclusion, body composition and leptin are related to the PCa aggressiveness but not with its prevalence.

Pre-hospital emergency care is a particularly vulnerable setting for workplace violence. However, there is no literature available to date on the psychological consequences of violence in pre-hospital emergency care. To evaluate the psychological consequences of exposure to workplace violence from patients and those accompanying them in pre-hospital emergency care. A retrospective cross-sectional study. 70 pre-hospital emergency care services located in Madrid region. A randomized sample of 441 health care workers (135 physicians, 127 nurses and 179 emergency care assistants). Data were collected from February to May 2012. The survey was divided into four sections: demographic/professional information, level of burnout determined by Maslach Burnout Inventory (MBI), mental health status using General Health Questionnaire (GHQ-28) and frequency and type of violent behaviour experienced by staff members. The health care professionals who had been exposed to physical and verbal violence presented a significantly higher percentage of anxiety, emotional exhaustion, depersonalization and burnout syndrome compared with those who had not been subjected to any aggression. Frequency of verbal violence (more than five times) was related to emotional exhaustion and depersonalization. Type of violence (i.e. physical aggression) is especially related to high anxiety levels and frequency of verbal aggression is associated with burnout (emotional exhaustion and depersonalization). Psychological counselling should be made available to professional staff who have been subjected to physical aggression or frequent verbal violence. Copyright © 2014 Elsevier Ltd.

Genetic variants of the monoamine oxidase A (MAOA) have been associated with aggression-, anxiety-, and addiction-related behavior in several nonclinical and clinical populations. Here, we investigated the influence of allelic variation of MAOA activity on aggression-related personality traits and disease risk in patients with personality disorders. Personality disorders were diagnosed with the Structured Clinical Interview of DSM-IV and were allocated to cluster A, B, and C. Personality features were assessed by the revised NEO Personality Inventory and the Tridimensional Personality Questionnaire. The genotype of the MAOA gene-linked polymorphic region (MAOA-LPR) was determined in 566 patients with personality disorders and in 281 healthy controls. MAOA genotype was significantly associated with cluster B personality disorders (chi2=7.77, p=0.005, df=1) but not with cluster C personality disorders. In total, 26.0% of cluster B patients were hemi- or homozygous for the low-activity variant of the MAOA genotype, compared to 16.4% in the control group. Associations between MAOA variants and personality domains related to impulsivity and aggressiveness were inconsistent. Our findings further support the notion that allelic variation of MAOA activity contributes modestly to the balance of hyper- (impulsive-aggressive) and hyporeactive (anxious-depressive) traits.

In previous studies, it has been demonstrated that high parental expressed emotion (EE) is predictive of depressive, aggressive and delinquency symptoms of adolescents. Two issues have received much less prominence in EE research, these being studies of adolescent perceived EE and the measurement of the EE as a dynamic, developmental construct. This 4-year, three-wave, longitudinal study of perceived EE of adolescents from the general community examines if adolescent perceived EE measured with the traditional, one-measurement EE approach as well as adolescent perceived EE measured with a repeated measured, dynamic EE approach can predict adolescent depressive, aggressive and delinquency symptoms. Dutch adolescents (N = 285; 51% girls; M = 13 years) from the general community were prospectively studied annually for 4 years. At all waves, the adolescents completed the Level of Expressed Emotion (LEE) questionnaire and at the final wave also completed self-rated measures of depressive, aggressive and delinquent symptoms. Growth models were used to predict adolescent symptoms from adolescent perceived EE. Growth models significantly predicted adolescent depressive, aggressive and delinquency symptoms from adolescent perceived EE. This study of the LEE demonstrates that developmental characteristics of EE are predictive of adolescents' symptoms. These findings hold implications for current EE intervention therapies and the conceptualization of EE.

In this longitudinal study, attributional and social processes involved in symptoms of mental health problems (depressive symptoms and aggressive behavior) were identified by investigating anxious and angry rejection sensitivity (RS), causal attributions of self-blame and peer-blame, and responses to rejection threat of withdrawal and retribution. Young adolescents (N = 713, grades 5-7) completed questionnaires three times in their regular classrooms over 14 months. Participants who reported more self-blame for rejection were more likely to withdraw in response to rejection threat, and withdrawal and anxious RS were associated with increased depressive symptoms at T3 relative to T1. In contrast, adolescents higher in the angry form of RS and who reported more peer-blame for rejection were more likely to seek retribution, which in turn was associated with more overt/relational aggressive behavior at T3 relative to T1. Depressive symptom level measured at T1 also was associated with later RS and coping with withdrawal, and aggressive behavior at T1 was associated with later retribution. Sex of the participants did not moderate any longitudinal associations, and only one prospective path, from T1 depressive symptoms to T2 RS anxious, was moderated by age.

Neighborhood noise pollution as a determinant of displaced aggression: a pilot study.

Noise pollution is still a growing public health problem with a significant impact on psychological health and well-being. The aim of this study was to investigate the impact of noise on displaced aggression (DA) in different subgroups of residents in one of the neighborhoods of Plovdiv city. A cross-sectional semi-structured interview survey was conducted using specially designed data registration forms and 33 close-ended and open-ended questions, divided into two major panels - one original and a modified version of the Displaced Aggression Questionnaire (DAQ). The mean score for DA was 61.12 (±19.97). Hearing noises above the perceived normal threshold, higher noise sensitivity and continuous noises were associated with higher levels of DA. Low frequency and high intensity noises were also associated with higher DA scores. Multiple regression model supported these findings. Contradictory to previous research age was positively correlated with noise sensitivity and aggression. We speculated that this might be due to the relatively lower socio-economic standard and quality of life in Bulgaria. Therefore, social climate might be modifying the way people perceive and react to environmental noise. Finally, the DAQ proved to be a viable measurement tool of these associations and might be further implemented and modified to suit the purposes of psychoacoustic assessment.

The aim of this study was to understand the relationship between egalitarianism, dominance, and intimate partner violence within the context of couples’ dynamics. In particular, it was hypothesized that dominance and sexist attitudes would have both self and partner effects on relationship aggression. To test this hypothesis, gender role egalitarianism, dominance/control, sexism, power dynamics, and aggression were assessed using several measures. Questionnaires for these measures were completed by 87 heterosexual dyads. The relationship between female and male scores on the dominance, egalitarianism, sexism, and intimate partner violence scales were examined using Actor-Partner Interdependence Model (APIM). Findings indicated that the APIM model provided a satisfactory fit to the data*. For both sexes, dominance had more explanatory power than sexism and egalitarianism when all else was controlled in the model. Furthermore, contrary to our expectation, male egalitarian attitude had no significant actor or partner effect on relationship aggression, while female egalitarian attitude had significant actor and partner effects on relationship aggression. Dyadic analysis indicated that cultural pointers of patriarchy, such as egalitarianism among young college students, were not associated with male-to-female violence. The sample size might also have an effect on this result in that a larger sample with older participants might yield different results. PMID:23123589

Correlates of self-injurious, aggressive and destructive behaviour in children under five who are at risk of developmental delay.

Several behavioural correlates of self-injury, aggression and destructive behaviour have been identified in children and young adults with intellectual disabilities. This cross-sectional study aimed to further explore these correlates in very young children with developmental delay. Parents of 56 children (40 male) under the age of five years (mean age 2 years 10 months) completed a questionnaire about their child's behaviour and the presence of behavioural correlates, including repetitive, over-active or impulsive behaviour and more severe developmental delay. Parents reported very high prevalence of self-injurious, aggressive and destructive behaviour: 51%, 64% and 51%, respectively. A binary logistic regression revealed that a higher score on a measure of overactive and impulsive behaviour significantly predicted the presence of destructive behaviour. A multiple linear regression revealed that both repetitive behaviour and number of health problems approached significance as independent predictors of severe self-injurious behaviour. Despite the very small sample, several factors emerged as potential predictors of self-injurious, aggressive and destructive behaviour. These findings support the need for further investigation in a larger sample. Confirmation in this age group could help guide the development of targeted early intervention for these behaviours by identifying behavioural risk markers. Copyright © 2013 Elsevier Ltd.

Background: This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents. Methods: This nationwide study was performed on a multi-stage sample of 6–18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey. Results: In this cross-sectional study, 13,486 students completed the study (90.6% participation rate); they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65). In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001). Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied) and (20% vs. 14%, P < 0.001 for bulling to others). Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61), while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69). Conclusions: Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended. PMID:25789141

Cyberbullying is the act of using unjustified aggression to harm or harass via digital devices. Currently regarded as a widespread problem, the phenomenon has attracted growing research interest in different measures of cyberbullying and the similarities and differences across countries and cultures. This article presents the Colombian validation of the European Cyberbullying Intervention Project Questionnaire (ECIPQ) involving 3,830 high school students (M = 13.9 years old, standard deviation = 1.61; 48.9 percent male), of which 1,931 were Colombian and 1,899 Spanish. Confirmatory factor analysis (CFA), content validation, and multigroup analysis were performed with each of the sample subgroups. The optimal fits and psychometric properties obtained confirm the robustness and suitability of the assessment instrument to jointly measure cyber-aggression and cyber-victimization. The results corroborated the theoretical construct and the two-dimensional and universal nature of cyberbullying. The multigroup analysis showed that cyberbullying dynamics are similar in both countries. The comparative analyses of prevalence revealed that Colombian students are less involved in cyberbullying. The results indicate the suitability of the instrument and the advantages of using such a tool to evaluate and guide psychoeducational interventions aimed at preventing cyberbullying in countries where few studies have been performed.

Modernization of the Driver Behaviour Questionnaire.

Cordazzo, Sheila T D; Scialfa, Charles T; Ross, Rachel Jones

2016-02-01

The current study builds on previous versions of the Driver Behaviour Questionnaire (DBQ) by incorporating a larger sample of driving behaviors targeting inattention, distraction, aggressive driving, and health related to aging. The goals of this study were to determine if the resulting factor structure was consistent with a more contemporary view of unsafe driving behaviors, and to determine whether scores on the factors could predict self-reported collisions and police citations. The instrument was given to a sample of 3295 drivers ranging in age from 19 to 80+ years old. It was divided in two sections, the first to provide demographic information and driving history data and the second containing 105 driver behavior questions. An exploratory factor analysis resulted in a 65-item scale organized in four factors. The factors were labeled tentatively as Inattention Errors, Age-Related Problems, Distraction and Hurry, and Aggressive Violations. Regression analyses showed that the factors were predictors of self-reported, at-fault collisions and police citations. The factor scores found in this research are consistent with a useful theoretical framework for understanding unsafe driver actions, and demonstrate some potential to identify several individual difference variables that predict self-reported collisions and citations.

Research on paranoia in adults suggests a spectrum of severity, but this dimensional approach has yet to be applied to children or to groups from different countries. To investigate the structure, prevalence and correlates of mistrust in children living in the U.K. and Hong Kong. Children aged 8-14 years from the U.K. (n = 1086) and Hong Kong (n = 1412) completed a newly developed mistrust questionnaire as well as standard questionnaire measures of anxiety, self-esteem, aggression and callous-unemotional traits. Confirmatory factor analysis of the U.K. data supported a three-factor mode--mistrust at home, mistrust at school and eneral mistrust - with a clear positive skew in the data: just 3.4%, 8.5% and 4.1% of the children endorsed at least half of the mistrust items for home, school and general subscales respectively. These findings were replicated in Hong Kong. Moreover, compared with their peers, 'mistrustful' children (in both countries) reported elevated rates of anxiety, low self-esteem, aggression and callous-unemotional traits. Mistrust may exist as a quantitative trait in children, which, as in adults, is associated with elevated risks of internalising and externalising problems. Royal College of Psychiatrists.

Comparing the validity of the self reporting questionnaire and the Afghan symptom checklist: dysphoria, aggression, and gender in transcultural assessment of mental health

2014-01-01

Background The relative performance of local and international assessment instruments is subject to ongoing discussion in transcultural research on mental health and psychosocial support. We examined the construct and external validity of two instruments, one developed for use in Afghanistan, the other developed by the World Health Organization for use in resource-poor settings. Methods We used data collected on 1003 Afghan adults (500 men, 503 women) randomly sampled at three sites in Afghanistan. We compared the 22-item Afghan Symptom Checklist (ASCL), a culturally-grounded assessment of psychosocial wellbeing, with Pashto and Dari versions of the 20-item Self-Reporting Questionnaire (SRQ-20). We derived subscales using exploratory and confirmatory factor analyses (EFA and CFA) and tested total and subscale scores for external validity with respect to lifetime trauma and household wealth using block model regressions. Results EFA suggested a three-factor structure for SRQ-20 - somatic complaints, negative affect, and emotional numbing - and a two-factor structure for ASCL - jigar khun (dysphoria) and aggression. Both factor models were supported by CFA in separate subsamples. Women had higher scores for each of the five subscales than men (p < 0.001), and larger bivariate associations with trauma (rs .24 to .29, and .10 to .19, women and men respectively) and household wealth (rs -.27 to -.39, and .05 to -.22, respectively). The three SRQ-20 subscales and the ASCL jigar khun subscale were equally associated with variance in trauma exposures. However, interactions between gender and jigar khun suggested that, relative to SRQ-20, the jigar khun subscale was more strongly associated with household wealth for women; similarly, gender interactions with aggression indicated that the aggression subscale was more strongly associated with trauma and wealth. Conclusions Two central elements of Afghan conceptualizations of mental distress - aggression and the syndrome jigar khun – were captured by the ASCL and not by the SRQ-20. The appropriateness of the culturally-grounded instrument was more salient for women, indicating that the validity of instruments may be gender-differentiated. Transcultural validation processes for tools measuring mental distress need to explicitly take gender into account. Culturally relevant measures are worth developing for long-term psychosocial programming. PMID:25034331

We investigated whether current mood and interest/pleasure ratings in adults with moderate to profound intellectual disabilities were predictive of challenging behaviour [self-injurious behaviour (SIB), aggressive/destructive behaviour and stereotypic behaviour] and vice versa. In this combined cross-sectional and longitudinal study, staff members of a Hungarian residential facility completed translated versions of the Behaviour Problems Inventory-Short Form (BPI-S), the Challenging Behaviour Interview (CBI) and the Mood, Interest and Pleasure Questionnaire-Short Form (MIPQ-S) for 50 participants at two time points, approximately 4 to 5 months apart. Bivariate correlations from data concurrently assessed at Time-1 showed significant linear relationships between the SIB (both frequency and severity scores) and Interest/Pleasure sub-scales, and the Aggressive/Destructive Behaviour (severity scores) and the MIPQ-S Mood sub-scales (unadjusted for multiple correlations). All of these effects were found with the BPI-S data, but not with the CBI. Multiple regression analyses revealed that (1) low interest/pleasure assessed at Time-1 predicted high SIB (frequency and severity) at Time-2. (2) Interest/pleasure was not predictive of aggressive or stereotypic behaviour. (3) Mood at Time-1 did not predict any of the three types of behaviour problems at Time-2. (4) In reverse, high SIB (frequency and severity) at Time-1 predicted low interest/pleasure ratings at Time-2. (5) Surprisingly, frequent aggressive/destructive behaviour predicted high interest/pleasure. (6) Stereotypic behaviour scores at Time-1 did not predict interest/pleasure ratings at Time-2. Again, all of these effects were only found with the BPI-S data, but not with the CBI. Internal consistency, test-retest reliability and concurrent validity of the Hungarian versions of all three questionnaires had generally satisfactory outcomes. The fact that increasingly frequent and severe SIB was predicted by declining measures of interest/pleasure is consistent with previous studies. Contrary to those earlier studies, however, we found that SIB was not predicted by mood and that aggressive/destructive behaviour actually predicted future elevated mood. Implications for future research regarding the directional relationship between affective states such as mood and interest and pleasure, on the one hand, and challenging behaviour, on the other, were discussed. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Calcium and dairy product intakes have been positively associated with prostate cancer risk. An imbalance in concentrations of calcium and magnesium has been associated with multiple chronic diseases, although few studies have examined the relation with prostate cancer aggressiveness. The goal of this study was to examine the association between dietary intakes of calcium and magnesium, the calcium-to-magnesium ratio (Ca:Mg), and dairy products and prostate cancer aggressiveness. Dietary intake was assessed with the use of an interviewer-administered modified National Cancer Institute Diet History Questionnaire in 996 African American and 1064 European American men with a recent histologically confirmed diagnosis of prostate cancer from the North Carolina-Louisiana Prostate Cancer Project (PCaP). High-aggressive disease was defined as Gleason sum ≥8, or prostate-specific antigen (PSA) >20 ng/mL, or Gleason score ≥7 and clinical stage T3-T4. The comparison group was all other prostate cancer cases. Logistic regression was used to determine the adjusted ORs and 95% CIs for high-aggressive prostate cancer by tertile of diet and supplement exposures. There was a positive association across tertiles of dietary Ca:Mg intake, with odds of high-aggressive prostate cancer in the upper tertiles as follows-OR for tertile 2 compared with tertile 1: 1.38 (95% CI: 1.01, 1.88); OR for tertile 3 compared with tertile 1: 1.46 (95% CI: 1.06, 2.02). When stratified by race, the positive association was more pronounced in African American men (OR for tertile 3 compared with tertile 2: 1.62; 95% CI: 1.04, 2.53). Men who reported the highest daily consumption of whole-fat milk had a 74% increased odds of high-aggressive prostate cancer compared with non-whole-fat milk drinkers, which was attenuated after adjustment for potential mediating factors, such as saturated fat and Ca:Mg intake. Among both African American and European American men diagnosed with prostate cancer, a higher Ca:Mg and whole-milk intake were associated with higher odds of high-aggressive prostate cancer. This study was registered at www.clinicaltrials.gov as NCT03289130.

This study tested a moderated-mediation model whereby dimensions of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) differentially predict perpetration of physical intimate partner aggression (IPA) through problematic drinking in intoxicated and nonintoxicated heavy drinkers. Participants were 249 heavy drinkers (148 men and 101 women) with a recent history of psychological and/or physical IPA perpetration toward their current partner recruited from 2 metropolitan U.S. cities. Participants completed questionnaires that assessed impulsivity and problematic drinking, consumed an Alcohol or No-Alcohol Control beverage, and completed a shock-based aggression task in which they were ostensibly provoked by their intimate partner. Results indicated an indirect effect of urgency on IPA through problematic drinking that was significantly more positive in intoxicated individuals. These findings implicate a tendency to act rashly in response to emotions as the specific dimension of impulsivity associated with problematic drinking, which in turn exacerbates risk for IPA perpetration. Results also suggest acute effects of alcohol are key in facilitating this mechanism. Copyright © 2017 by the Research Society on Alcoholism.

Physicians during their work activities have been exposed to suffering physical and non-physical aggression (insults, threats, sexual assaults and even murder) by patients. The frequency of such attacks has increased in recent years. The aim of this study is to identify the risk of attacks on physicians associated with the type of work place that health institutions have assigned them for their year of social service in Mexico. A cross-sectional questionnaire survey was conducted during 2012 of 371 physicians who were assigned to work in various community health centers called type "A", "B" or "C". Having worked in a work place type "C" was associated with physical aggression (OR: 2.32; 95% CI: 1.03-5.37), threats (OR: 2.64; 95% CI: 1.43-4.93), and insults (OR: 2.28; 95% CI: 1.35-3.88). The results should be interpreted with caution, but they suggest that physicians who are assigned to work in the places type "C" (where they must care for patients in a solitary manner and at night) during the year of social service in Mexico have a significant risk of being attacked.

Can We Clinically Recognize a Vascular Depression?

2015-01-01

Abstract The vascular depression (VD) hypothesis postulates that cerebrovascular disease may “predispose, precipitate, or perpetuate” a depressive syndrome in elderly patients. Clinical presentation of VD has been shown to differ to major depression in quantitative disability; however, as little research has been made toward qualitative phenomenological differences in the personality aspects of the symptom profile, clinical diagnosis remains a challenge. We attempted to identify differences in clinical presentation between depression patients (n = 50) with (n = 25) and without (n = 25) vascular disease using questionnaires to assess depression, affect regulation, object relations, aggressiveness, alexithymia, personality functioning, personality traits, and counter transference. We were able to show that patients with vascular dysfunction and depression exhibit significantly higher aggressive and auto-aggressive tendencies due to a lower tolerance threshold. These data indicate that VD is a separate clinical entity and secondly that the role of personality itself may be a component of the disease process. We propose an expanded threshold disease model incorporating personality functioning and mood changes. Such findings might also aid the development of a screening program, by serving as differential criteria, ameliorating the diagnostic procedure. PMID:25950684

Objective This study compared women who sex trade for drugs, money, or both compared to neither (did not sex trade), and introduced the concept of trait displaced aggression to the literature on sex trading. Methods Female participants (n = 1055) were recruited from a low-income area of southern California. Measures included: the Risk Behavior Assessment (RBA), Barratt Impulsivity Scale (BIS), Eysenck Impulsiveness Scale (EIS), and the Displaced Aggression Questionnaire (DAQ). Results Women who traded sex for both drugs and money used crack cocaine, powder cocaine, and alcohol significantly more, scored higher on the BIS, and the EIS, and were significantly older. Those who only sex traded for drugs used more amphetamine, heroin, and injected drugs more days. They were also higher on the DAQ and all of the DAQ subscales. Those who traded for money only used marijuana more and were more likely to use marijuana before sex. Conclusions This study may help address specific issues unique to those who sex trade for different commodities in that the drugs used are different and the underlying personality characteristics are different.

We describe the development and psychometric characteristics of the Generalized Workplace Harassment Questionnaire (GWHQ), a 29-item instrument developed to assess harassing experiences at work in five conceptual domains: verbal aggression, disrespect, isolation/exclusion, threats/bribes, and physical aggression. Over 1700 current and former university employees completed the GWHQ at three time points. Factor analytic results at each wave of data suggested a five-factor solution that did not correspond to the original five conceptual factors. We suggest a revised scoring scheme for the GWHQ utilizing four of the empirically extracted factors: covert hostility, verbal hostility, manipulation, and physical hostility. Covert hostility was the most frequently experienced type of harassment, followed by verbal hostility, manipulation, and physical hostility. Verbal hostility, covert hostility, and manipulation were found to be significant predictors of psychological distress.

Effects of altruism and burnout on driving behavior of bus drivers.

Personality traits predict driving behaviors. However, the mechanism underlying this relationship has not been adequately investigated in professional drivers. The current study investigated the relationship between altruistic personality and aberrant driving behaviors, and the potential role of burnout. A total of 194 bus drivers completed questionnaires including measures of altruism, burnout and aberrant driving behaviors (aggressive violations, ordinary violations, errors, and lapses). The results showed that altruism was negatively correlated with burnout, and with all the four subcategories of aberrant driving behavior. Burnout fully mediated the relationship between altruism and aggressive violations, and partially mediated the relationship between altruism and lapses. These findings can be applied in the bus drivers' selection and interventions for burnout in order to improve the safety of public transport. Copyright © 2017 Elsevier Ltd. All rights reserved.

The onset of behavioral problems starts in early life. This study examined whether excessive infant crying (maternal ratings) is a determinant of emotional and behavioral problems at age 5-6 years. In the Amsterdam Born Children and their Development (ABCD) study, a large prospective, observational, population-based multiethnic birth cohort, excessive infant crying (crying for three or more hours per 24 h day over the past week) during the 13th week after birth (range 11-25 weeks, SD 2 weeks), maternal burden of infant care and maternal aggressive behavior (either angry speaking, or physical aggression) was assessed using a questionnaire. Children's behavioral and emotional problems at the age of 5-6 were assessed by Goodman's Strengths and Difficulties Questionnaire (SDQ), by the subscale of generalized anxiety of the preschool anxiety scale (PAS), and by the Short Mood and Feelings Questionnaire (SMFQ). Inclusion criterion was singleton birth. Exclusion criteria were preterm born babies or congenital disorders. Among 3389 children, excessive infant crying (n = 102) was associated with a twofold increased risk of the overall problem behavior, conduct problems, hyperactivity, and mood problems at the age of 5-6 [ORs between 1.75 (95 % CI 1.09-2.81) and 2.12 (95 % CI 1.30-3.46)]. This association was mediated by maternal burden of infant care (change in odds' ratio 1-17 %) and maternal aggressive behavior (change in odds' ratio 4-10 %). There was no effect modification by the child's gender or maternal parity. Excessive infant crying was not associated with general anxiety problems. Excessive infant crying doubles the risk of behavioral, hyperactivity, and mood problems at the age of 5-6, as reported by their mother. Maternal burden of infant care partially mediates the association between excessive crying and behavioral and mood problems. Special care for mothers with a high burden of care for their excessive crying infant, notwithstanding their own good health, can be a feasible strategy for possible prevention of mood and behavioral problems in their children later in life.

To determine the views of care home (CH) staff in relation to experiencing and managing behaviour that challenges (BtC) in dementia and their experiences of training. Cross-sectional survey using a self-report questionnaire, distributed to staff employed in a 20% sample of all registered dementia-specialist CHs in England, either by postal or direct distribution. Questionnaires were returned from 352 care staff (25%), representing 5% of all dementia-specialist CHs, half were CH without nursing. Respondents estimated caring for 14,585 residents, 9,361 with dementia and 5,258 with BtC. 30.2% of residents with dementia were estimated as being prescribed a medicine to control BtC. BtC reported as experienced by most respondents were: shouting (96.6%), verbal aggression (96.3%) and physical aggression (95.7%), with physical aggression viewed as most difficult to manage. Top behaviours experienced every shift were: wandering (77.8%), perseveration (68.2%) and restlessness (68.2%). Approaches such as assessing residents, knowing them and treating them as individuals, identifying triggers, having time for them and using an appropriate style of communication, were viewed as key to managing BtC, rather than guideline-specific interventions such as massage, aromatherapy and animal-assisted therapy. Only 38% agreed/strongly agreed medicines were useful to control BtC, which was related to the extent to which they were prescribed. Training was available, but variable in quality with on-line training being least useful and on-the job training most desirable. BtC are commonly and frequently experienced by care staff, who consider individual approaches, having time and good communication are key to successful management.

To understand the evolution of personality structure requires examining personality dimensions in multiple species using a common set of traits. Little research has been conducted on personality in wild populations of nonhuman primates. Using behavioral observations and questionnaire ratings, we examined factors influencing personality in 16 wild bonobos (Pan paniscus) at Wamba, Luo Scientific Reserve, Democratic Republic of the Congo. We extracted five factors from 31 of the items from the Hominoid Personality Questionnaire (HPQ) and three factors from observed behaviors. The HPQ factors were labeled Unemotionality Q , Friendliness Q , Aggressiveness Q , Irritability Q , and Activity Q . The behavioral factors were labeled Grooming B , Playfulness B , and Introversion B . We established the convergent and divergent validity of these factors by obtaining correlations between the HPQ and behavioral factors. We tested for sex differences and found that males were significantly higher on Introversion B and significantly lower in Irritability Q . We then tested for age differences and found that Friendliness Q was lower and Aggressiveness Q was higher in older individuals. Finally, we found that, among males, hierarchical rank was associated with higher Aggressiveness Q . These findings contrast with findings in chimpanzees in ways consistent with known species differences. For one, consistent with the more egalitarian structure of bonobo society, we did not identify a clear Dominance factor. Also, the results related to sex differences were consistent with previous findings that reveal closer bonds between female bonobos than female chimpanzees. These findings highlight the importance of studying personality in closely related species and the need to consider species' socioecology when studying personality. Am. J.

2013-01-01

The current study examined the explanatory role of satisfaction of parental psychological needs in effects of childhood aggression on various adolescent-perceived parenting behaviors in middle adolescence. Research questions were examined in a large multi-informant, prospective community study of ethnic majority Belgian families (N = 609, 49.7% girls). Aggression was rated by parents when children were in middle childhood (M age = 7.5 years) using the Child Behavior Checklist. Parents reported on satisfaction of their needs for autonomy, competence, and relatedness when children were in preadolescence (M age = 10.5 years) and early adolescence (M age = 13.5 years) using the Parenting Stress Index. Parenting behaviors were rated by adolescents in early adolescence (M age = 13.5 years) and in middle adolescence (M age = 15.5 years), using the Parenting Scale (overreactive discipline), the Psychological Control Scale, Youth Self-Report (psychological control), and the Parenting Practices Questionnaire (warmth). Mediation of associations from aggression to parenting by parents' psychological needs was examined using multiple mediation structural equation modeling analyses. Childhood aggression was related to decreased satisfaction of parents' needs for competence, relatedness, and autonomy in early adolescence. Satisfaction of parents' needs for relatedness and, to a lesser extent, competence affected later parenting, and satisfaction of all three needs affected changes in parenting. Relations were specific for the different parenting constructs but similar across parental gender. Targeting parents' psychological needs may aid effectiveness of interventions that are aimed at decreasing (psychologically, overreactive) controlling parenting and at increasing supportive parenting.

Individuals with psychopathy have an increased tendency toward certain types of aggression. We hypothesized that successful psychopaths, who have no criminal convictions but can be diagnosed with psychopathy in terms of personality characteristics, are skilled at regulating aggressive impulses, compared to incarcerated unsuccessful psychopaths. In this block-designed functional magnetic resonance imaging (fMRI) study, we sought to clarify the neural mechanisms underlying differences in frustration-induced aggression as a function of psychopathy in non-criminal populations. Twenty male undergraduate students who completed a self-report psychopathy questionnaire were scanned while they completed a task in which they either could or could not punish other individuals who made unfair offers of monetary distribution. Individuals with high psychopathic tendencies were less likely to make a decision to inflict costly punishment on people proposing unfair offers. During this decision-making, psychopathy was associated with less amygdala activity in response to the unfairness of offers. Moreover, the amygdala dysfunction in psychopathic individuals was associated with reduced functional connectivity with dopaminergic-related areas, including the striatum, when punishment was available compared to when it was unavailable. The possibility that levels of psychopathic traits in a regular population were milder than in incarcerated populations cannot be ruled out. The findings indicate that amygdala dysfunction underlies affective deficits of psychopathy. We propose that the insensitivity of the amygdala to the affective significance of social stimuli contributes to an increased risk of violation of social norms, but enhances the ability to attenuate impulses toward maladaptive aggression in successful psychopaths.

Experience-based human perception of facial expressions in Barbary macaques (Macaca sylvanus)

PubMed Central

Levy, Xandria; Meints, Kerstin; Majolo, Bonaventura

2017-01-01

Background Facial expressions convey key cues of human emotions, and may also be important for interspecies interactions. The universality hypothesis suggests that six basic emotions (anger, disgust, fear, happiness, sadness, and surprise) should be expressed by similar facial expressions in close phylogenetic species such as humans and nonhuman primates. However, some facial expressions have been shown to differ in meaning between humans and nonhuman primates like macaques. This ambiguity in signalling emotion can lead to an increased risk of aggression and injuries for both humans and animals. This raises serious concerns for activities such as wildlife tourism where humans closely interact with wild animals. Understanding what factors (i.e., experience and type of emotion) affect ability to recognise emotional state of nonhuman primates, based on their facial expressions, can enable us to test the validity of the universality hypothesis, as well as reduce the risk of aggression and potential injuries in wildlife tourism. Methods The present study investigated whether different levels of experience of Barbary macaques, Macaca sylvanus, affect the ability to correctly assess different facial expressions related to aggressive, distressed, friendly or neutral states, using an online questionnaire. Participants’ level of experience was defined as either: (1) naïve: never worked with nonhuman primates and never or rarely encountered live Barbary macaques; (2) exposed: shown pictures of the different Barbary macaques’ facial expressions along with the description and the corresponding emotion prior to undertaking the questionnaire; (3) expert: worked with Barbary macaques for at least two months. Results Experience with Barbary macaques was associated with better performance in judging their emotional state. Simple exposure to pictures of macaques’ facial expressions improved the ability of inexperienced participants to better discriminate neutral and distressed faces, and a trend was found for aggressive faces. However, these participants, even when previously exposed to pictures, had difficulties in recognising aggressive, distressed and friendly faces above chance level. Discussion These results do not support the universality hypothesis as exposed and naïve participants had difficulties in correctly identifying aggressive, distressed and friendly faces. Exposure to facial expressions improved their correct recognition. In addition, the findings suggest that providing simple exposure to 2D pictures (for example, information signs explaining animals’ facial signalling in zoos or animal parks) is not a sufficient educational tool to reduce tourists’ misinterpretations of macaque emotion. Additional measures, such as keeping a safe distance between tourists and wild animals, as well as reinforcing learning via videos or supervised visits led by expert guides, could reduce such issues and improve both animal welfare and tourist experience.

The aim of this randomized controlled trial was to investigate the effect of an Internet-delivered cognitive behaviour therapy (iCBT), which incorporated emotion-regulation and conflict-resolution techniques, on intimate partner violence (IPV). Another aim was to test the theoretical underpinnings of the treatment model using mediation analysis. Sixty-five participants with aggression problems in intimate adult relationships were recruited from the community and were randomly assigned to iCBT or to a monitored waitlist control. Participants were assessed with standardized self-report measures of IPV or aggression (Multidimensional Measure of Emotional Abuse, Revised Conflict Tactics Scale, and Aggression Questionnaire), relationship quality (Dyadic Adjustment Scale), anxiety or depression symptomatology (Patient Health Questionnaire; Generalized Anxiety Disorder Screener), at pretreatment, posttreatment (8 weeks), and 1-year follow-up. Process variables (subscales of Dysfunctional and Emotional Regulation Scale and Anger Rumination Scale) were assessed weekly over the active treatment phase. Robust linear regression analysis of all randomized participants showed significant treatment effects on emotional abuse relative to control at postassessment. Mediation analysis using growth curve modeling revealed that the treatment effect was partially mediated by changes in emotion-regulation ability. Controlled effects on secondary outcomes were also observed. Analyses of uncontrolled effects indicted that gains on IPV were maintained at 1-year follow-up. iCBT focusing on enhancing conflict-resolution skills and emotion-regulation ability has the potential to reduce IPV among self-recruited individuals with mild forms of abusive behaviour in intimate relationships. Emotion-regulation ability is potentially a key therapeutic process of change. Internet-delivered clinician-guided cognitive behaviour therapy is a viable treatment option for reducing intimate partner violence among self-recruited individuals with mild forms of abusive behaviour. For persons who display patterns of frequent and severe violence, other treatments are most likely needed. Emotion-regulation training is potentially a key therapeutic component that ought to be incorporated in interventions targeting IPV. Copyright © 2017 John Wiley & Sons, Ltd.

School violence is a growing problem that has received widespread attention. Violent behavior for elementary school children is primarily expressed as physical or verbal aggression. Various factors contribute to violent and aggression by children at homes, schools or individual risk factors. The aim of the present study is to measure the prevalence of violence, risk factors, and different forms among elementary school children, to identify consequence of violent exposure and children with abnormal behavior score. A cross-sectional study was done enrolling a total of 500 elementary students from two mixed schools (private and public) 250 from each in North Cairo Educational Zone. Data collected from students, parents and teachers were: violence behavior, home and family atmosphere, peer relation, exposure to violence at school; being victimized, witness, or initiator, and other risk factors. Standardized questionnaires were used as Achenback Child Behavior checklist, parent and teacher forms of Strength and Difficulty questionnaires (SDQ), and developmental history of child. Monthly grades of students, IQ assessment, physical examination of students were recorded. Prevalence of different forms of violence was higher in public school than private; physical violence 76%, 62% respectively. All forms of violence were higher among boys. Living with a single parent (OR = 2.3), absence of an attachment figure (OR = 13.6), instrumental delivery or cesarean section (OR = 1.9), corporal punishment (OR = 3), violent video games preference (OR = 2.5), exposure to verbal aggression (OR = 3), relations with aggressive peers (OR = 3) were risk factors for violence. Teacher's report of SDQ revealed abnormal score of student's behavior in (32.4%) and (22%) students of public and private schools respectively. The most frequent problems revealed by SDQ among victimized students of both schools was conduct problems (64.7%) in teacher's report and peer relation problems 93.6% in parent's report. Abnormal and borderline scores of SDQ are high among studied students, Follow up and supervision is needed to prevent violence among them. An effective role model to direct student's behavior should receive more concern at the school and home level.

Some antibullying interventions have shown positive outcomes with regard to reducing violence. The aim of the study was to experimentally assess the effects on school violence and aggressiveness of a program to prevent and reduce cyberbullying. The sample was comprised of a randomly selected sample of 176 adolescents (93 experimental, 83 control), aged 13–15 years. The study used a repeated measures pre-posttest design with a control group. Before and after the program, two assessment instruments were administered: the “Cuestionario de Violencia Escolar-Revisado” (CUVE-R [School Violence Questionnaire – Revised]; Álvarez-García et al., 2011) and the “Cuestionario de agresividad premeditada e impulsiva” (CAPI-A [Premeditated and Impulsive Aggressiveness Questionnaire]; Andreu, 2010). The intervention consisted of 19 one-hour sessions carried out during the school term. The program contains 25 activities with the following objectives: (1) to identify and conceptualize bullying/cyberbullying; (2) to analyze the consequences of bullying/cyberbullying, promoting participants’ capacity to report such actions when they are discovered; (3) to develop coping strategies to prevent and reduce bullying/cyberbullying; and (4) to achieve other transversal goals, such as developing positive variables (empathy, active listening, social skills, constructive conflict resolution, etc.). The pre-posttest ANCOVAs confirmed that the program stimulated a decrease in: (1) diverse types of school violence—teachers’ violence toward students (ridiculing or publicly humiliating students in front of the class, etc.); students’ physical violence (fights, blows, shoves… aimed at the victim, or at his or her property, etc.); students’ verbal violence (using offensive language, cruel, embarrassing, or insulting words… toward classmates and teachers); social exclusion (rejection or exclusion of a person or group, etc.), and violence through Information and Communication Technologies (ICT; violent behaviors by means of electronic instruments such as mobile phones and the Internet)—; and (2) premeditated and impulsive aggressiveness. Pre-posttest MANCOVA revealed differences between conditions with a medium effect size. This work contributes an efficacious intervention tool for the prevention and reduction of peer violence. The conclusions drawn from this study have interesting implications for educational and clinical intervention. PMID:27064802

Rates of aggression and delinquency are assumed to be higher among Roma and other minorities, but sound evidence of this is lacking. Our aim was to assess delinquent and aggressive behavior among Roma and non-Roma adolescents and the effects on ethnic differences of parental education and social desirability. We conducted a cross-sectional study among Roma from separated and segregated settlements in the eastern part of Slovakia (N = 330; Mage = 14.50; interview) and non-Roma adolescents (N = 722; Mage = 14.86; questionnaire). The effect of ethnicity on antisocial behaviors was analyzed using linear regression (crude) and adjusted for gender, parental education, and social desirability. Adjustment for social desirability diminished the ethnic differences in delinquency (B = 1.08; 95% confidence interval [CI] = [2.12, -0.04]), led to an increase in the differences in hostility (B = 2.43; 95% CI = [0.87, 3.99]), and led to the disappearance of differences in physical aggression (B = 0.45; 95% CI = [1.14, 2.07]). Parental education did not affect the associations in an important way. Our findings indicate that Roma are not that much different from non-Roma, in terms of antisocial behavior, which contradicts the general perception of Roma. Our findings should be confirmed in other settings. © The Author(s) 2014.

Objective: The purpose of the current research was to examine the impact of both maternal and paternal alcoholism on the relationship functioning of husbands and wives over the early years of marriage. Method: Couples (N = 634) were assessed at the time of marriage, and again at their first, second, and fourth anniversaries. Husbands and wives completed separate, self-administered questionnaires at home. Results: Results of separate repeated measures analyses of covariance revealed that, for both husbands and wives, the appraisal of their marital relationship was associated with alcoholism in the opposite gender parent. That is, for husbands, alcoholism in the mother was associated with lower marital satisfaction across the 4 years of marriage. For wives, alcoholism in the father was related to lower marital intimacy. Husbands' physical aggression was influenced by mother's and father's alcoholism; high levels of physical aggression were present among men with alcoholic mothers and nonalcoholic fathers. Interestingly, wives' experience of husband's aggression was also highest among women with alcoholic mothers and nonalcoholic fathers. Wives also reported engaging in high levels of physical aggression when they had an alcoholic mother and a nonalcoholic father, but this effect was restricted to the early part of the marriage. Finally, parental alcoholism was associated with both husbands' and wives' attachment representations. Conclusions: The present findings suggest that children raised in alcoholic families may carry the problematic effects of their early family environment into their adult romantic relationships.

The current study aimed to assess Jordanian parents' knowledge and beliefs about the effects of violent media on children's aggressive behavior. A sample of 262 parents of children aged 6-11 years completed a Media Quotient questionnaire about children's media habits, media effects, and children's aggressive behavior. Parents reported that their children spend an average of 4.83 h (SD = 2.12) watching TV, 3.20 h (SD = 2.29) playing video games, 1.07 h (SD = 0.88) listening to music, and only 0.52 min (SD = 0.67) reading for pleasure per day. Parents have a moderate level of knowledge about the media effect (M = 15.49, SD = 3.439). Children of parents who have adequate knowledge about the media effect, spend less time watching TV (r = -.355, p < .001), playing video games (r = -.265, p < .001), and listening to music (r = -.347, p < .001). Ninety-two percent (n = 241) of parents were concerned about the amount of sexual and of violent content their children see in movies or on TV. Children who spend more time playing video games (r = -.201, p = .004) show aggressive relational behavior. This study suggests that increasing parents' knowledge of media of evidence-based programs may have a protective effect on children's behavior.

Father absence and gendered traits in sons and daughters.

Boothroyd, Lynda G; Cross, Catharine P

2017-01-01

Research has previously found a number of apparently contradictory patterns in the relationship between 'father absence' (having a non-resident father during childhood) and the expression of gender roles, as well as other sexually dimorphic traits such as aggression. In the current study we measured a battery of sexually differentiated traits in relation to family background. 133 men and 558 women from the United States and Australia completed the Bem Sex Role Inventory, the Barrett Impulsivity Scale, the Fear Survey Schedule and the Buss & Perry Aggression Questionnaire. Principal components analysis found two main axes of variation in these traits. Firstly, a general 'reactivity' factor, on which aggression, impulsivity, and fear all loaded positively, was weakly associated with father absence in women. Secondly, 'masculinity' (consisting of high scores on masculine traits, low fear, and physical and verbal aggression) was not associated with father absence. Participants (except American males) reporting a poor childhood relationship with their parents also had high 'reactivity' but not higher 'masculinity'. We found some evidence of a link between father absence and earlier age of first coitus in American females (although not in Australia), but there was no link with age of menarche in either country. Overall, the current results suggest that previous findings linking gender development with father absence in girls may have arisen from a tendency towards greater externalising and reactive behaviour rather than a change in gender development per se.

It is surprising to note the evolution of success rates in Belgian universities especially in the first Year. Men are less successful than women and the differences are escalating in an alarming way. Dropouts take the same direction and women now represent a majority of the students at the university. In a previous study, we assessed 616 students in the first Year at the university of Liège with Vasev, the English name of which was TASTE, a self report questionnaire constituted of 4 factors: anxiety, self confidence, procrastination and performance value; anxiety particularly concerned somatic expression of students before and during test evaluations; self confidence was a cognitive component close to self efficacy; procrastination was the behavioral component characterizing avoidance when students are confronted with the risk of failure; performance value referred to intrinsic and extrinsic motivations. French validation of TASTE led to an abbreviated version of 50 items (THEE) consisting of 5 factors, the four of TASTE and an additional one, very consistent, at first called depression because of its correlations with this dimension, then called sense of competence on account of its semantic content. Self-competence has been described in the literature of Achievement Motivation and corresponded to expectancy and ability beliefs in performance process which was also relevant to self-efficacy except the particularity of comparison with others, which was not included in the last construct. Self-competence has been considered as an important part of the Worry component of test anxiety. Some Authors didn't hesitate to view causality flowing from self-competence to test anxiety and have conceptualized the latter as a failure of the self where one's sense of competence has been undermined as a result of experienced failure. In our study, only that factor was equally scored in women and men whereas it was scored higher in failed students. In other respects anxiety and performance value were scored higher in women, self-confidence and procrastination higher in men. Because TASTE didn't discriminate the different components of motivation (performance value referred to intrinsic and extrinsic motivations without precise distinction) we decided to use the MPS (Multidimensional Perfectionism Scale) which gave the opportunity to distinguish SOP (Self Oriented Perfectionism) ie, the self-imposed unrealistic standards with inability to accept faults in order to know and master a subject, that corresponded to intrinsic motivation; SPP (Socially Prescribed Perfectionism) ie, the exaggerated expectancies of others which are subjectively believed as imposed and uncontrollable leading to anxiety, feelings of failure or helplessness, that corresponded to extrinsic motivation; POO (Perfectionism Oriented to Others) ie, the unrealistic demands expected from significant others, which especially characterized males. We assumed that women attached more importance to succeed and submitted more to society exigencies. That way extrinsic and intrinsic motivations were probably more combined unlike men who, dreading a loss of self esteem, tried to avoid failure responsibility in using self handicapping or aggressive behaviours, so separating motivation in an extrinsic part turned to performance value and an intrinsic one more concerned by self confidence and sense of competence with the result that the motivational balance was surely disrupted in case of high competition leading to failure or avoidance. In another previous study we established a structural model illustrating, according to gender, correlations between anxiety, sense of incompetence, self-oriented perfectionism and socially prescribed perfectionism. Self-oriented perfectionism was less correlated to socially prescribed perfectionism in boys than in girls; furthermore especially by those who had never failed, it was negatively correlated to sense of incompetence, thus leading to lower scores of anxiety while in girls, by contrast, such a correlation didn't exist, thus involving higher anxiety. That way, on the one hand, intrinsic and extrinsic motivations by female students complementarily operated on the sense of incompetence and consequently on anxiety, the emotional component of test anxiety; on the other hand, by male students, intrinsic motivation had a negative correlation with the sense of incompetence and a lower correlation with extrinsic motivation, thereby shedding some light on the problem of anxiety level differences according to gender. More, that observation corresponded well to the model of self-worth where test anxiety was understood as a manifestation of perceived incompetence and as a defensive way to ward off negative self-evaluation; that model suited particularly well to boys and explained their attempts to maintain self-worth when risking academic failure. The present research assumes that independence or combination of motivation components is also correlated to different expressions of aggressiveness: hostility corresponding to threat and characterizing more girls while physical aggression is corresponding to personal challenge, a more masculine attribution. If fighting against the sense of incompetence actually characterizes men and consequently shows too the competitive aspects of performance strong enough to mobilize intrinsic motivation, what would be expected regarding the notion of threat suspected to be predominant in girls? The idea of using a questionnaire discriminating the specific dimensions of aggressiveness in fact the Aggression Questionnaire should meet the following purposes: At first establish a French version of that aggression questionnaire, perform the factorial analyses and internal consistency, compare them with other previous samples, then differentiate gender in general and in failure versus success situations. Finally include the different components of aggressiveness in the first described model and build a new one liable to define in boys the explicit pathways between test anxiety, perfectionism and aggressiveness. Statistical analyses have confirmed, in a 3 factor solution, the presence of emotional (anger), cognitive (hostility) and behavioural (physical aggression) components. Internal consistency is satisfactory. It is demonstrated that physical aggression characterizes boys (F=12.04, p=0.0001) while hostility (F=5.22, p=0.0015) and anger (F=0.49, p=0.0001) characterizes girls; furthermore it is noted that physical aggression characterizes more failed students (F=13.43, p=0.0003). Four models (see figures 2, 3, 4, 5) have been established, at first focused on the distinction of correlations between motivation and cognitive and emotional components on the samples of boys (n=268) and girls (348), then developed on the samples of successful students, male (n=193) and female (n=271). They describe the differentiated action of intrinsic and extrinsic motivations on the different components of aggressiveness and test-anxiety according to gender and without experience of failure. The dynamic process of the organizational factors is different according to gender and psychopathology resulting from the combinations of behaviors, cognitions and emotions would be assumed, prioritizing physical aggression and psychopathy by boys, anxiety and depression by girls. Anyway more explanation about the evolution of success rates of boys and girls in Belgian universities is proposed.

Explanatory style, dispositional optimism, and reported parental behavior.

Hjelle, L A; Busch, E A; Warren, J E

The relationship between two cognitive personality constructs (explanatory style and dispositional optimism) and retrospective self-reports of maternal and paternal behavior were investigated. College students (62 men and 145 women) completed the Life Orientation Test, Attributional Style Questionnaire, and Parental Acceptance-Rejection Questionnaire in a single session. As predicted, dispositional optimism was positively correlated with reported maternal and paternal warmth/acceptance and negatively correlated with aggression/hostility, neglect/indifference, and undifferentiated rejection during middle childhood. Unexpectedly, explanatory style was found to be more strongly associated with retrospective reports of paternal as opposed to maternal behavior. The implications of these results for future research concerning the developmental antecedents of differences in explanatory style and dispositional optimism are discussed.

To ensure the most efficient workplace health promotion it is essential to identify and monitor health conditions of employees and all components of the work process, as well as to recognize their cause-effect relationships. Community nurses form an occupational group with a specific type of workplace that is usually located in the patient's place of residence and thus not inspected in terms of safety and hygiene. The aim of the study was to identify working conditions of community nurses with special reference to occupational hazards. An anonymous questionnaire was used as a major tool of this survey. It contained 33 questions, concerning the work process, working conditions, work loads and arduousness, hazards and work-related complaints. The questionnaire was completed by 86 community nurses working in the Upper Silesia region. Community nurses generally assessed their work as hard. A more thorough analysis revealed that nursing and curative care, nursing and hygienic care and rehabilitation were regarded by community nurses as hard, whereas social diagnostics and curative diagnostics were assessed as much easier tasks. Excessive physical load, forced position at work, aggressive patients, patients' aggressive family members, dangerous domestic animals, low quality of technical devices in patients' homes were reported as the greatest hazards. The obtained results reveal that working conditions of community nurses do not ensure their safety at work.

We explored differences between high and low-impulsive incarcerated individuals in the context of lifetime self-mutilation, suicide ideation and suicide attempt. A total of 1265 males detained in Italian penitentiary institutions were studied between January 2006 and December 2008. The study raters were specifically trained to discriminate between suicide attempters, ideators and self-mutilators. Participants completed the Barratt Impulsivity Scale, Childhood Trauma Questionnaire (CTQ), Eysenck Personality Questionnaire (EPQ), Connor-Davidson Resilience Scale (CD-RISC), Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA) and Buss and Durkee Hostility Inventory (BDHI). Based on BIS 7 total score distribution, two extreme quarters - high-impulsive group (n=306) and low-impulsive group (n=285) - were compared. Over 42% of participants had lifetime suicide ideation, 13% attempted suicide and 17% were self-mutilators. High-impulsive subjects were younger, more often single and with more prominent psychoticism, extraversion, aggression, hostility and resilience capacity. They were more frequently diagnosed with substance use disorders and engaged in self-mutilating behaviour. There was no difference in the rate of suicide attempts between the two groups. Although high-impulsive subjects were more prone to suicidal behaviour, it was not predicted by higher impulsivity when other psychological variables were accounted for. Copyright 2010 Elsevier B.V.

We conducted a questionnaire investigation among breeding farmers to clarify the actual conditions of maternal rejection in Japanese Black cattle. We asked keeping experience of maternal rejective cows and compared occurrence patterns, rejective behavior manners, birth assistance methods, colostrum feeding method for calves, parity and rearing conditions of the cows. We found that 24% of the farms had kept rejective cows and 6% of the cows in these farms indicated maternal rejections. The most common occurrence pattern was 'Occurred from the first birth (65.6%)' and behavior manner was performing no maternal grooming with aggressive behavior (75%). Almost all the farmers assisted in each parturition (P < 0.05). There was not a significant difference among the colostrum feeding methods, but a significant difference in the rearing conditions of the cows, except for the cows with no data (P < 0.005). The parity of the rejective cows did not significantly differ in association with rejective behavior manners, birth assistance methods, colostrum feeding methods or rearing conditions. These results suggest that the occurrence rate of maternal rejection in Japanese Black cattle was approximately 6% and many of the rejective cows continuously performed no maternal grooming with aggressive behavior. © 2017 Japanese Society of Animal Science.

Seventh-grade students (N = 324) completed social cognitive maps to identify peer groups and peer group leaders, sociometric nominations to describe their peers’ behaviors, and questionnaires to assess their own behaviors. Peer group members resembled one another in levels of direct and indirect aggression and substance use; girls’ cliques were more behaviorally homogenous than were boys’ cliques. On average, leaders (especially if they were boys) were perceived as engaging in more problem behaviors than were nonleaders. In girls’ cliques, peripheral group members were more similar to their group leader on indirect aggression than were girls who were more central to the clique. Peer leaders perceived themselves as being more able to influence peers but did not differ from nonleaders in their perceived susceptibility to peer influence. The findings contribute to our understanding of processes through which influence may occur in adolescent peer groups. PMID:19763241

Are cyberbullies less empathic? Adolescents' cyberbullying behavior and empathic responsiveness.

2011-11-01

Meta-analyses confirm a negative relationship between aggressive behavior and empathy, that is, the ability to understand and share the feelings of others. Based on theoretical considerations, it was, therefore, hypothesized that a lack of empathic responsiveness may be characteristic for cyberbullies in particular. In the present study, 2.070 students of Luxembourg secondary schools completed an online survey that included a cyberbullying questionnaire(4) and a novel empathy short scale. According to the main hypothesis, analyses of variances indicated that cyberbullies demonstrated less empathic responsiveness than non-cyberbullies. In addition, cyberbullies were also more afraid of becoming victims of cyberbullying. The findings confirm and substantially extend the research on the relationship between empathy and aggressive behavior. From an educational point of view, the present findings suggest that training of empathy skills might be an important tool to decrease cyberbullying.

This study examined the relationship between parent-child social networking, connection, and outcomes for adolescents. Participants (491 adolescents and their parents) completed a number of questionnaires on social networking use, feelings of connection, and behavioral outcomes. Social networking with parents was associated with increased connection between parents and adolescents. Feelings of connection then mediated the relationship between social networking with parents and behavioral outcomes, including higher prosocial behavior and lower relational aggression and internalizing behavior. Conversely, adolescent social networking use without parents was associated with negative outcomes, such as increased relational aggression, internalizing behaviors, delinquency, and decreased feelings of connection. These results indicate that although high levels of social networking use may be problematic for some individuals, social networking with parents may potentially strengthen parent-child relationships and then lead to positive outcomes for adolescents.

This paper presents further results from a study of married women in Edinburgh who had just suffered an adverse experience: either their husband's non-fatal myocardial infarction, their husband's death or their own arrival in a Women's Aid refuge for battered women. Interviews were carried out 4-6 weeks following the adverse experience and, where possible, again approximately 3 months later. Symptoms were assessed using the 30-item General Health Questionnaire and criterion-based measures of depression and anxiety derived from it. The extent and nature of crisis support from household members and from groups of people outside the household, and also of failures in expected support, was measured at first interview. A modified version of Tyrer and Alexander's (1979) personality schedule was administered at the follow-up interview, and the resulting personality data were then reduced to six factors using principal components analysis. An interviewer assessment of how well the subject was coping was made at both interviews. The vast majority of the sample received extensive practical and emotional support from family and friends, and perhaps because such positive support was so prevalent, variations in it seemed to have little effect on symptoms. However, subjects who were unexpectedly 'let down' or criticised by friends or family tended to show higher symptom levels, although, surprisingly, this was less true for the bereaved wives than for the others. The six personality factors that emerged were labelled nervousness (similar to neuroticism) impulsivity, social withdrawal, helplessness, inferiority and aggressiveness. There was evidence that subjects high on nervousness remained symptomatic longer following the adverse experience. The aggressiveness factor showed a curvilinear trend with high and low aggressives showing higher symptom levels than middle aggressives. However, for the coronary wives the trend was linear with low aggressives having high symptoms. Subjects low on impulsivity were more affected by being 'let down' by friends and family. The interviewer-assessed coping measure was linearly related to nervousness and showed a curvilinear relationship with aggressiveness.

Background Life in the low-income urban communities of South Africa is imprinted by a cycle of violence in which young males predominantly are in the roles of both victim and perpetrator. There is some evidence that adolescents who show an attraction to cruelty can display high levels of psychosocial functioning despite the presence of posttraumatic stress symptoms. However, the role of appetitive aggression in the context of ongoing threats and daily hassles is not yet fully understood. Objective In this study, we examine the role of attraction to violence in areas of continuous traumatic stress exposure and its effect on posttraumatic stress disorder (PTSD) severity and violence perpetration. Method A sample of 290 young males from two low-income Cape Town communities was surveyed. We assessed appetitive aggression with the Appetitive Aggression Scale (AAS), PTSD symptoms with the PTSD Symptom Scale-Interview, the number of witnessed and self-experienced traumatic event types with an adaptation of the Child Exposure to Community Violence questionnaire, and the number of perpetrated violence event types with an adapted offence checklist from the AAS. Results Appetitive aggression scores were predicted by witnessed as well as self-experienced traumatic events. Higher appetitive aggression scores resulted in higher levels of PTSD severity and perpetrated violence. Conclusions Young males living in the low-income areas of South Africa may develop an attraction to cruelty in response to exposure to violence. Their willingness to fight in turn can increase the likelihood of continued violent behaviour. In contrast to previous research from postconflict areas, appetitive aggression and engagement in violence do not prevent the development of PTSD, but are instead associated with higher levels of posttraumatic stress. PTSD symptoms such as avoidance and hyperarousal, as well as an attraction to cruelty and thus the willingness to fight, might support survival in areas of ongoing conflict, but at the same time they could fuel the cycle of violence.

Suicidal behavior and self-mutilation can be regarded as the expression of self-directed aggression and both are common in prison populations. We investigated the influence of externalizing behaviors, depressive symptoms, childhood trauma, 5-HTTLPR variants on self-directed aggression (N = 145) in a group of 702 male Italian prisoners. Participants were comprehensively evaluated, including for psychiatric disorders, impulsive traits, lifetime aggressive behavior [Brown-Goodwin Lifetime History of Aggression (BGHA)], hostility, violent behavior during incarceration, depressive symptomatology [Hamilton Depression Rating Scale (HDRS)], childhood trauma [Childhood Trauma Questionnaire (CTQ)]. Logistic regression analysis showed false discovery rate corrected independent main effects of externalizing behaviors: BGHA (P = 0.001), violent behavior in jail (P = 0.007), extraversion (P = 0.015); HDRS (P = 0.0004), Axis I disorders (P = 0.015), CTQ (P = 0.004) and 5-HTTLPR genotype (P = 0.02). Carriers of 5-HTTLPR high (LA LA ), intermediate (LA LG , SLA ) activity variants were more likely to have exhibited self-directed aggression relative to the low activity (LG LG , SLG , SS) variant: high/low: odds ratio (OR) = 2.3, 95% confidence interval (CI) 1.27-4.68, P = 0.007; intermediate/low: OR = 1.96, 95% CI 1.09-3.68, P = 0.025. The CTQ main effect was driven by physical abuse. There was no interactive effect of 5-HTTLPR and CTQ. Secondary logistic regression analyses in (1) all suicide attempters (N = 88) and (2) all self-mutilators (N = 104), compared with controls showed that in both groups, childhood trauma (P = 0.008-0.01), depression (P = 0.0004-0.001) were strong predictors. BGHA, violent behavior in jail predicted self-mutilation (P = 0.002) but not suicide attempts (P = 0.1). This study was able to distinguish differing influences on self-directed aggression between groups of closely related predictor variables within the externalizing behavioral domain. 5-HTTLPR had an independent, variant dosage effect. © 2016 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

Objectives This study examined mothers’ and fathers’ reporting congruency using the Parent-Child Conflict Tactics Scales. We asked if the mother's report of the father's parenting aggression was consistent with the father's self-report of parenting aggression and if the father's report of the mother's parenting aggression was consistent with the mother's self- report of those same behaviors. We assessed moderators of parental reporting congruency: severity of the aggression, interparental conflict, child temperament, and child gender. Methods Participants were from the Child Development Project, a longitudinal study beginning when children were in kindergarten. The analyses herein included 163 children for whom 2 parents provided data about their own and their spouse or partner's behavior toward the child. Most parents (87%) were married. Mothers and fathers independently completed the Parent-Child Conflict Tactics Scale, both with respect to their own behavior toward the child and with respect to their partner's behavior toward the child. Mothers completed the retrospective Infant Characteristics Questionnaire to assess child temperament. Mothers and fathers completed measures of interparental conflict. Results Both fathers and mothers self-reported more frequently engaging in each behavior than the other parent reported they did. Parents were more congruent on items assessing harsher parenting behavior. Furthermore, there was more agreement between parents regarding fathers’ behavior than mothers’ behavior. Analyses of interparental conflict, child difficult temperament, and child gender as moderators yielded findings suggesting that mothers’ and fathers’ reports of their own and their spouses’ harsh parenting behaviors were more concordant in couples with low levels of conflict, for children with easy temperaments, and for boys versus girls. Conclusions Prior studies indicate only a moderate level of agreement in couples’ reports of violence between intimate partners and suggest that perpetrators tend to underreport their use of aggression. The results of this study suggest that parents may be more consistent in their reports of parent to child violence using the Parent-Child Conflict Tactics Scales than they are when reporting intimate partner violence. The results suggest that parental reports of their spouse's parent to child aggression are reliable. PMID:22763358

To examine the prevalence of aggression against healthcare professionals and to determine the possible impact that violent episodes have on healthcare professionals in terms of loss of enthusiasm and involvement towards work. The objective was to analyse the percentage of occupational assault against professionals' aggression in different types of healthcare services, differentiating between physical and verbal aggression as a possible variable in detecting burnout in doctors and nursing professionals. Leiter and Maslach have explored a double process model of burnout not only based on exhaustion by overload, but also based on personal and organisational value conflicts (community, rewards or values). Moreover, Whittington has obtained conclusive results about the possible relationship between violence and burnout in mental health nurses. A retrospective study was performed in three hospitals and 22 primary care centres in Spain (n = 1·826). Through different questionnaires, we have explored the relationship between aggression suffered by healthcare workers and burnout. Eleven percent of respondents had been physically assaulted on at least one occasion, whilst 34·4% had suffered threats and intimidation on at least one occasion and 36·6% had been subjected to insults. Both forms of violence, physical and non-physical aggression, showed significant correlations with symptoms of burnout (emotional exhaustion, depersonalisation and inefficacy). The survey showed evidence of a double process: (1) by which excess workload helps predict burnout, and (2) by which a mismatch in the congruence of values, or interpersonal conflict, contributes in a meaningful way to each of the dimensions of burnout, adding overhead to the process of exhaustion-cynicism-lack of realisation. Relevance to clinical practice.  Studies indicate that health professionals are some of the most exposed to disorders steaming from psychosocial risks and a high comorbidity: anxiety, depression, etc. There is a clear need for accurate instruments of evaluation to detect not only the burnout but also the areas that cause it. Professional exhaustion caused by aggression or other factors can reflect a deterioration in the healthcare relationship. © 2012 Blackwell Publishing Ltd.

There is growing evidence of the protective role of dietary intake of flavonoids and lignans on cancer, but the association with bladder cancer has not been thoroughly investigated in epidemiological studies. We evaluated the association between dietary intakes of total and subclasses of flavonoids and lignans and risk of bladder cancer and its main morphological type, urothelial cell carcinoma (UCC), within the European Prospective Investigation into Cancer and Nutrition (EPIC) study. A cohort of 477 312 men and women mostly aged 35-70 years, were recruited in 10 European countries. At baseline, dietary flavonoid and lignan intakes were estimated using centre-specific validated questionnaires and a food composition database based on the Phenol-Explorer, the UK Food Standards Agency and the US Department of Agriculture databases. During an average of 11 years of follow-up, 1575 new cases of primary bladder cancer were identified, of which 1425 were UCC (classified into aggressive (n=430) and non-aggressive (n=413) UCC). No association was found between total flavonoid intake and bladder cancer risk. Among flavonoid subclasses, significant inverse associations with bladder cancer risk were found for intakes of flavonol (hazard ratio comparing fifth with first quintile (HRQ5-Q1) 0.74, 95% confidence interval (CI): 0.61-0.91; P-trend=0.009) and lignans (HRQ5-Q1 0.78, 95% CI: 0.62-0.96; P-trend=0.046). Similar results were observed for overall UCC and aggressive UCC, but not for non-aggressive UCC. Our study suggests an inverse association between the dietary intakes of flavonols and lignans and risk of bladder cancer, particularly aggressive UCC.

Risk factors of violence perpetration in veterans include substance use and posttraumatic stress disorder (PTSD); however, it is unknown whether these factors are associated with greater risk for partner or non-partner violence. This study investigated the associations between probable PTSD, heavy drinking, marijuana use, cocaine use, and partner and non-partner violence perpetration. Self-report questionnaires assessing past-year partner and non-partner aggression (CTS2) as well as past-month substance use (SAOM), probable PTSD (PCL-C), and probable depression (PHQ-9) were administered to 810 substance using veterans entering VA mental health treatment. In bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, χ 2 =11.46, p=0.001, φ=0.12; non-partner physical, χ 2 =50.64, p<0.001, φ=0.25; partner injury, χ 2 =6.41, p=0.011, φ=0.09; non-partner injury, χ 2 =42.71, p<0.001, φ=0.23). In multiple logistic regression analyses that adjusted for sociodemographic characteristics, probable PTSD was independently associated with non-partner physical (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.97-4.05) and injury aggression (OR, 3.96; CI, 2.56-6.13). Cocaine and heavy drinking were independently associated with non-partner physical and injury aggression and non-partner injury aggression respectively. The results provide evidence that probable PTSD, heavy drinking, and cocaine use are associated with increased risk of non-partner violence perpetration in substance using veterans. These results underscore the importance of screening for PTSD symptoms and violence perpetration towards non-partners in substance using veterans presenting for treatment. Published by Elsevier Ltd.

Genetic and environmental influences on child psychopathology have been studied extensively through twin and adoption designs. We offer a novel methodology to examine genetic and environmental influences on the intergenerational transmission of psychopathology using a sample of parents and children conceived through in vitro fertilization (IVF). The sample included families with children born through IVF methods, who varied as to whether the child was genetically related or unrelated to the rearing mother and father (mother genetically related, n=434; mother genetically unrelated, n=127; father genetically related, n=403; father genetically unrelated, n=156). Using standardized questionnaires, mothers and fathers respectively reported on their own psychopathology (depression, aggression), their parenting behavior toward their child (warmth, hostility) and their child's psychopathology (depression, aggression). A cross-rater approach was used, where opposite parents reported on child symptoms (i.e. fathers reported on symptoms for the mother-child dyad, and vice versa). For mother-child dyads, a direct association between mother depression and child depression was observed among genetically unrelated dyads, whereas a fully mediated path was observed among genetically related dyads through mother-to-child hostility and warmth. For father-child dyads, direct and mediated pathways were observed for genetically related father-child dyads. For aggression, the direct association between parent aggression and child aggression was fully mediated by parent-to-child hostility for both groups, indicating the role of parent-to-child hostility as a risk mechanism for transmission. A differential pattern of genetic and environmental mediation underlying the intergenerational transmission of psychopathology was observed among genetically related and genetically unrelated father-child and mother-child dyads.

Our aim was to evaluate whether quality of life (QOL) scores at diagnosis predict survival among patients with aggressive lymphoma. Newly diagnosed lymphoma patients were prospectively enrolled within 9 months of diagnosis in the University of Iowa/Mayo Clinic SPORE and systematically followed for event-free and overall survival (OS). QOL was measured with the Functional Assessment of Cancer Treatment-General (FACT-G), which measures 4 domains: physical, social/family, emotional, and functional well-being (WB); a single item Linear Analogue Self-Assessment (LASA) measuring overall QOL; and a spiritual WB LASA. From 9/2002 to 12/2009, 701 patients with aggressive lymphoma who completed baseline QOL questionnaires were enrolled. At a median follow-up of 71 months (range 6-128), 316 patients (45%) had an event and 228 patients (33%) died. All baseline QOL measures but emotional WB were significantly associated with OS (all P < 0.04); of which all but LASA spiritual remained significant after adjusting for IPI and NHL subtype. The strongest associations were with total FACT-G (adjusted HR = 0.86, 95% CI: 0.79-0.94, P = 0.00062) and functional WB (adjusted HR = 0.88, 95% CI: 0.83-0.93, P < .0001). QOL LASA was associated with OS (adjusted HR = 0.92, 95% CI: 0.87-0.97, P = 0.0041). Patients with clinically deficient QOL (overall QOL ≤50) had a median OS of 92 months compared with 121 months for patients with QOL >50 (P = 0.0004). In this large sample of patients with aggressive lymphoma, we found that baseline QOL is independently predictive of OS. QOL should be assessed as a prognostic factor in patients with aggressive lymphoma. Copyright © 2018 John Wiley & Sons, Ltd.

In the study we conducted we aimed at investigating the relation between personality profiles and risk diet behaviors in teenagers. This study was a case-control one and we applied 2 questionnaires (Freiburg Personality Inventory--FPI with 212 items) and CORT 2004 (items Q94-Q116 of diet behavior) on a sample of 2908 teenagers (51.5% girls and 48.5% boys). Cronbach's alpha index was 0.802 for FPI and 0.730 for items Q101-Q109 of CORT. Personality profiles were built by an Excel 2003 Program. Statistical analysis was realized with SPSS 16 program applying Chi square (chi2) and gamma (gamma) correlation. Personality features of teenagers with high and without risk diet behavior were analyzed. Results obtained: personality profiles and statistical results indicated the existence of a significant statistical difference of aggressiveness and domination between teenagers with high and no consumption of butter and/or lard (Q103) (chi2 = 6.872, Sig. 0.032 and chi2 = 6.922, Sig. 0.031 respectively), of juices from the market (Q106) (chi2 = 9.055, Sig. 0.011 and chi2 = 14.571, Sig. 0.001 respectively). Aggressiveness correlated with consumption of fried potatoes (Q109) (chi2 = 6.144, Sig. 0.046) too. Correlation gamma indicated direct proportional relations of aggressiveness with: Q103 (gamma = 0.215, Sig. 0.017), Q106 (gamma = 0.224, Sig. 0.004), Q109 (gamma = 0.242, Sig. 0.012); and of domination with: Q103 (gamma = 0.234, Sig. 0.008), Q106 (gamma = 0.073, Sig. 0.000). In conclusion, there is a direct proportional relation between consumption of: butter/lard, juices from the market and teenagers' aggressiveness, domination; and a similar relation between consumption of fried potatoes and aggressiveness.

Personality traits predict treatment outcome with an antidepressant in patients with functional gastrointestinal disorder.

We investigated the relationship between personality traits and response to treatment with the tetracyclic antidepressant mianserin or placebo in patients with functional gastrointestinal disorder (FGD) without psychopathology. Forty-eight patients completed the Buss-Durkee Hostility Inventory, Neuroticism Extroversion Openness -Personality Inventory (NEO-PI), and Eysenck Personality Questionnaire (EPQ), neuroticism + lie subscales, before they were consecutively allocated to a 7-week double-blind treatment study with mianserin or placebo. Treatment response to pain and target symptoms were recorded daily with the Visual Analogue Scale and Clinical Global Improvement Scale at every visit. A low level of neuroticism and little concealed aggressiveness predicted treatment outcome with the antidepressant drug mianserin in non-psychiatric patients with FGD. Inversely, moderate to high neuroticism and marked concealed aggressiveness predicted poor response to treatment. These findings were most prominent in women. Personality traits were better predictors of treatment outcome than serotonergic sensitivity assessed with the fenfluramine test. Assessment of the personality traits negativism, irritability, aggression, and neuroticism may predict response to drug treatment of FGD even when serotonergic sensitivity is controlled for. If confirmed in future studies, the findings point towards a more differential psychopharmacologic treatment of FGD.

Evidence for early disease-modifying drugs in rheumatoid arthritis

2004-01-01

Some research evidence supports early aggressive treatment of rheumatoid arthritis (RA) using combination therapy with two or more disease modifying anti-rheumatic drugs (DMARDs) plus steroids, or even DMARDs plus an anti-TNF. By contrast, conservatively delayed DMARD monotherapy, given after non-steroidal anti-inflammatory drugs have failed, has been criticised. However, recent long-term studies highlight the complexities in evaluating whether to abandon pyramidal treatment in favour of early DMARDs. Although patients given early DMARD therapy show short-term benefits, longer-term results show no prolonged clinical advantages from early DMARDs. By 5 years patients receiving early DMARDs had similar disease activity and comparable health assessment questionnaire scores to patients who received DMARDs later in their disease course. X-ray progression was persistent and virtually identical in both groups. These negative findings do not invalidate the case for early DMARD therapy, as it is gives sustained reductions in disease activity in the early years of treatment without excessive risks from adverse effects. However, early DMARDs alone do not adequately control RA in the longer term. This may require starting with very aggressive therapy or treating patients more aggressively after early DMARD therapy has been initiated. PMID:14979927

During May, 2006, on one acute mental health inpatient unit, nursing staff evaluated each patient three times a day (i.e., once each nursing shift) using the Broset Violence Checklist (BVC). Associated data were collected using the Staff Observation and Aggression Scale-Revised (SOAS-R) if an adverse incident occurred. At the end of the data collection period, the nursing staff were asked to complete a short questionnaire anonymously to evaluate how useful they had found the instruments. N = 93 patients were admitted to the unit during the month of study. Seven incidents were reported using the SOAS-R. A slight trend was noted for higher BVC score in aggressive patients. A potential high occurrence of underreporting on incidents was observed. There was limited feedback data from nursing staff at the end of the study, but the responses received were encouraging for continued use of the instruments in practice. The pilot study fulfilled its purpose in two ways. First, it allowed staff on the unit to experience using structured instruments to support their practice. Second, it allowed an opportunity to raise awareness of potential underreporting and tolerance of aggression on the unit.

Objective The objective of the present study was to determine whether and how personality predicts the developmental course of externalizing problems, including antisocial behavior and substance dependence. Method In a large population-based longitudinal study (N=1252), the 11 personality traits assessed by the Multidimensional Personality Questionnaire were measured at age 17, and DSM diagnoses of adult antisocial behavior, alcohol dependence, and drug dependence were obtained at ages 17, 20, 24, and 29. We fit a quadratic multiple indicator latent growth model where the three diagnoses loaded onto an externalizing factor. Results This model fit the data well, and externalizing increased until it started to decline at age 24. High aggression and low control were the most significant predictors of the development of externalizing, with aggression playing a significant role in the development of externalizing across the 12-year time span, and control predicting the development from age 17 to 24. Conclusions The findings highlight the importance of considering the developmental course of externalizing in the context of personality and suggest that the specific personality traits of aggression and control might be targeted in externalizing prevention and intervention programs.

In Turkey, the cultural structure effects the gender roles in the society, and women are subject to violence in an intense manner both inside the family and in their workplaces. In nursing, which is still defined as a woman's job in our country, it is possible to encounter many aggressive and threatening behaviours. Knowing no geographical borders, aggression leads to dissatisfaction and alienation with the profession for the nurses working at the psychiatric institutions in Turkey, thus aggression is a significant health risk in physical, psychological and social dimensions. The research was carried out with 162 randomly selected nurses working in the psychiatric institutions in Istanbul using the Attitudes Toward Patient Physical Assault Questionnaire. It has been determined that nurses' rate of exposure to verbal/physical assault by the patients and their relatives is high and that they experience an intense uncertainty and conflict, especially in legal issues, and that the duration of working in the psychiatry clinics effects attitudes toward the assaults. It is concluded that the nurses working at the psychiatry clinics in Turkey are under risk in regards to safety and they need protection and support, both in emotional and in legal terms.

Workplace violence is a common risk for mental health professionals, and psychiatrists often encounter it in a variety of settings. The aim of this study was to estimate the prevalence and features of violent episodes toward psychiatrists in various mental healthcare system settings. All psychiatrists from the Region of Puglia (Apulia) were contacted (N=285) via email and were administered an on-line standardized questionnaire. The response rate by psychiatrists was 57%. The main types of violence revealed were "threats" and "verbal aggression" and, of particular importance, "stalking". Female psychiatrists seemed to be at a higher risk of becoming victims of workplace violence, especially as regards verbal abuse (OR: 2.7, 95% CI: 1.2-6.5, c2 6.7, p=0.0095) and reported more serious psychological consequences with need for rest after the episode of aggression. Our data confirm that mental health workers, particularly psychiatrists, are healthcare professionals at high risk for workplace violence. Future implementation of preventive strategies with the aim of reducing aggressive episodes towards psychiatrists should be a high priority for managers and policy-makers operating in the Italian healthcare sector.

Oppositional defiant disorder (ODD) is very frequent in preschoolers. The severity and the long-term negative outcomes make the understanding of this disorder a priority. The goal in this study was to assess the mediating role of parenting practices in the relationship between parents' psychopathology and ODD in preschoolers. A community sample of 622 children was assessed longitudinally at age 3 and age 5. Parents reported on children's psychopathology through a diagnostic interview, and on their own psychological state and parenting style through questionnaires. At ages 3 and 5, corporal punishment mediated the relationships between mothers' anxiety-depression and ODD (in girls), between mothers' aggressive behavior and ODD (in boys), and between parents' rule-breaking and ODD both in boys and girls. For both sexes, there was a direct association between mothers' aggressive behavior score and ODD. The association between fathers' psychopathology and ODD was not mediated by the fathers' parenting practices. Fathers' anxiety-depression and aggressive behavior scores were directly associated with ODD. Parents' psychopathology must be explored and, in families where such psychopathology is a relevant variable, parenting practices must be addressed with a view to the prevention and treatment of children's ODD in the preschool years.

The main objective of this study is to study the personality types in children with aerophagia. A cross sectional survey was conducted in 8 randomly selected schools in 4 randomly selected provinces Sri Lanka. From each school, all cchildren aged 13-18 years were selected after obtaining written consent from parents, school administration and provincial education office. Assent was obtained from all children recruited. Date were collected using a self-administered questionnaire administered under examination setting to ensure confidentiality and privacy. Questionnaire contained previously translated and validated Rome III questionnaire for functional gastrointestinal diseases (self-administered form for children above 10 years) and childhood personality assessment questionnaire. Trained research assistants were present during filling the questionnaire to provide assistance and to verify doubts. Aerophagia was defined using the Rome III criteria. Severities of individual symptoms were recorded in 100 mm visual analogue scale. A total of 1069 questionnaires were distributed and all of them were returned and included in analysis [males 508 (47.5%), mean age 15.3 years, SD 1.8 years years]. One hundred and thirty six (12.7%) fulfilled Rome III criteria for aerophagia and 933 children without aerophagia were considered as controls. Nineteen (13.8%) children with aerophagia and 71 (7.6%) controls had personality scores above the international cut-off value (105) for abnormal personality (p = 0.01). Children with aerophagia had significantly higher scores for different personality traits than controls; including hostility and aggression (13.2 vs. 12.2 in controls, p = 0.006), negative self-esteem (11.0 vs. 9.9, p < 0.0001), negative self-adequacy (10.6 vs. 9.6, p = 0.001), emotional unresponsiveness (10.5 vs. 9.6, p < 0.0001), emotional instability (16.9 vs. 15.7, p < 0.001), negative world view (10.9 vs. 10.1, p = 0.02) and total personality score (92.1 vs. 87.7, p = 001). In children with aerophagia, scores obtained for severity of bloating correlated with scores obtained for hostility and aggression (r = 0.22, p = 0.02). Children with aerophagia has abnormal personality traits and this fact may at least partly responsible for development and perpetuation of symptoms in them.

Development of a screening questionnaire for DSM-5 intermittent explosive disorder (IED-SQ).

2017-04-01

This study was designed to develop and test a screening approach to identify individuals with DSM-5 Intermittent Explosive Disorder (IED), a disorder of recurrent, problematic, impulsive aggression. A screening approach to diagnose DSM-5 IED (IED-SQ) was developed by combining items related to life history of aggression and items related to the DSM-5 diagnostic criteria for IED. In study 1, the IED-SQ was studied in 72 adult participants; 33 that met DSM-5 criteria for lifetime IED and 39 that did not. In study 2, the IED-SQ was given to 740 undergraduates at a US university. Measures of aggression and anger expression and anger control were assessed in both studies. In study 1, the IED-SQ demonstrated strong concordance with the best estimate diagnoses (Kappa =.80) for lifetime IED by DSM-5 criteria and good test-retest reliability (kappa =0.71). In study 2, the IED-SQ identified 4.3% of the undergraduate sample as meeting DSM-5 criteria for lifetime IED, a rate comparable to that in recent epidemiological studies. Participants identified as meeting DSM-5 criteria for lifetime IED, in both studies, had higher aggression scores, and higher anger expression, and lower anger control scores, compared to participants that did not meet DSM-5 criteria for lifetime IED. These data suggest that the IED-SQ is a useful screening tool that can quickly identify the presence of IED by DSM-5 criteria in adults. Copyright © 2016 Elsevier Inc. All rights reserved.

A self-medication hypothesis has been proposed to explain the association between cannabis use and psychiatric and behavioral problems. However, little is known about the reasons for use and reactions while intoxicated in cannabis users who suffer from depression or problems controlling violent behavior. We assessed 119 cannabis-dependent subjects using the Schedules of Clinical Assessment in Neuropsychiatry (SCAN), parts of the Addiction Severity Index (ASI), and questionnaires on reasons for cannabis use and reactions to cannabis use while intoxicated. Participants with lifetime depression and problems controlling violent behavior were compared to subjects without such problems. Validity of the groupings was corroborated by use of a psychiatric treatment register, previous use of psychotropic medication and convictions for violence. Subjects with lifetime depression used cannabis for the same reasons as others. While under the influence of cannabis, they more often experienced depression, sadness, anxiety and paranoia, and they were less likely to report happiness or euphoria. Participants reporting problems controlling violent behavior more often used cannabis to decrease aggression, decrease suspiciousness, and for relaxation; while intoxicated they more often reacted with aggression. Subjects with prior depression do not use cannabis as a mean of self-medication. They are more likely to experience specific increases of adverse symptoms while under the influence of cannabis, and are less likely to experience specific symptom relief. There is some evidence that cannabis is used as a means of self-medication for problems controlling aggression.

Does playing violent video games cause aggression? A longitudinal intervention study.

It is a widespread concern that violent video games promote aggression, reduce pro-social behaviour, increase impulsivity and interfere with cognition as well as mood in its players. Previous experimental studies have focussed on short-term effects of violent video gameplay on aggression, yet there are reasons to believe that these effects are mostly the result of priming. In contrast, the present study is the first to investigate the effects of long-term violent video gameplay using a large battery of tests spanning questionnaires, behavioural measures of aggression, sexist attitudes, empathy and interpersonal competencies, impulsivity-related constructs (such as sensation seeking, boredom proneness, risk taking, delay discounting), mental health (depressivity, anxiety) as well as executive control functions, before and after 2 months of gameplay. Our participants played the violent video game Grand Theft Auto V, the non-violent video game The Sims 3 or no game at all for 2 months on a daily basis. No significant changes were observed, neither when comparing the group playing a violent video game to a group playing a non-violent game, nor to a passive control group. Also, no effects were observed between baseline and posttest directly after the intervention, nor between baseline and a follow-up assessment 2 months after the intervention period had ended. The present results thus provide strong evidence against the frequently debated negative effects of playing violent video games in adults and will therefore help to communicate a more realistic scientific perspective on the effects of violent video gaming.

Father absence and gendered traits in sons and daughters

Boothroyd, Lynda G.

2017-01-01

Research has previously found a number of apparently contradictory patterns in the relationship between ‘father absence’ (having a non-resident father during childhood) and the expression of gender roles, as well as other sexually dimorphic traits such as aggression. In the current study we measured a battery of sexually differentiated traits in relation to family background. 133 men and 558 women from the United States and Australia completed the Bem Sex Role Inventory, the Barrett Impulsivity Scale, the Fear Survey Schedule and the Buss & Perry Aggression Questionnaire. Principal components analysis found two main axes of variation in these traits. Firstly, a general ‘reactivity’ factor, on which aggression, impulsivity, and fear all loaded positively, was weakly associated with father absence in women. Secondly, ‘masculinity’ (consisting of high scores on masculine traits, low fear, and physical and verbal aggression) was not associated with father absence. Participants (except American males) reporting a poor childhood relationship with their parents also had high ‘reactivity’ but not higher ‘masculinity’. We found some evidence of a link between father absence and earlier age of first coitus in American females (although not in Australia), but there was no link with age of menarche in either country. Overall, the current results suggest that previous findings linking gender development with father absence in girls may have arisen from a tendency towards greater externalising and reactive behaviour rather than a change in gender development per se.

Of the 122 legal medicine physicians, 39 (32%) were exposed to specific threats, 8 (6.6%) were exposed to physical action without injury, and 7 (5.7%) had experience serious incidents including threats with a weapon or attacks leading to physical injury over the previous year. Even assuming that all the nonresponders did not experience any violence, the aggression by patients affected 75% of legal medicine practitioners in the Tehran province. : Violence toward Tehran's legal medicine practitioners is very common and may be increasing. Some of the participating factors of aggression are potentially avoidable and practices should make strenuous attempts to identify such factors and remedy them. Staff training in interpersonal skills and recognizing anxious patients are essential. Doctors should avoid delays for patients by rearranging the booking policies, visit times, and duration. Victims of aggression must be followed up.

2008-01-01

The present study was designed to evaluate psychiatric risk factors for child and adolescent suicide, and to determine the association between impulsive-aggressive and other personality traits, and suicide completion in this population. Psychiatric diagnoses, impulsive-aggressive and other personality traits were assessed in 55 child and adolescent suicide victims and 55 community controls using semi-structured proxy-based interviews and questionnaires. The most significant psychiatric risk factors associated with child and adolescent suicide were depressive disorders (OR=48.414, 95% CI 6.247-375.185), substance/alcohol abuse disorder (OR=5.365, 95% CI 1.434-20.076), and disruptive disorders (OR=13.643, 95% CI 2.292-23.16). Additionally, suicide victims showed higher scores on lifetime aggression/impulsivity, and harm avoidance. However, after logistic regression, the only independent significant predictors of suicide in this age group were the presence of depressive disorders (Adjusted OR (AOR)=39.652, 95% CI 4.501-349.345), substance/alcohol abuse disorders (AOR=7.325, 95% CI 1.127-47.62), and disruptive disorders (AOR=6.464, 95% CI 1.422-29.38). Relatively small sample size, and cross-sectional design. Our findings confirm the existence of a particular clinical profile of children and adolescents at high risk for suicide. Additionally, our results reinforce the need for improved understanding of the interrelationships between stressors, depression, substance/alcohol abuse disorders, disruptive disorders and personality traits/dimensions in youth suicidal behavior.

Workplace violence prevalence has attracted significant attention within the international nursing literature. Little attention to non-mental health settings and a lack of evaluation rigor have been identified within review literature. To examine the effects of a workplace violence training program in relation to risk assessment and management practices, de-escalation skills, breakaway techniques, and confidence levels, within an acute hospital setting. A quasi-experimental study of nurses using pretest-posttest measurements of educational objectives and confidence levels, with two week follow-up. A 440 bed metropolitan tertiary referral hospital in Sydney, Australia. Nurses working in specialties identified as a 'high risk' for violence. A pre-post-test design was used with participants attending a one day workshop. The workshop evaluation comprised the use of two validated questionnaires: the Continuing Professional Development Reaction questionnaire, and the Confidence in Coping with Patient Aggression Instrument. Descriptive and inferential statistics were calculated. The paired t-test was used to assess the statistical significance of changes in the clinical behaviour intention and confidence scores from pre- to post-intervention. Cohen's d effect sizes were calculated to determine the extent of the significant results. Seventy-eight participants completed both pre- and post-workshop evaluation questionnaires. Statistically significant increases in behaviour intention scores were found in fourteen of the fifteen constructs relating to the three broad workshop objectives, and confidence ratings, with medium to large effect sizes observed in some constructs. A significant increase in overall confidence in coping with patient aggression was also found post-test with large effect size. Positive results were observed from the workplace violence training. Training needs to be complimented by a multi-faceted organisational approach which includes governance, quality and review processes. Copyright © 2018 Elsevier Ltd. All rights reserved.

The German Version of the Humor Styles Questionnaire: Psychometric Properties and Overlap With Other Styles of Humor

Ruch, Willibald; Heintz, Sonja

2016-01-01

The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16–24, 25–35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80–.89), with lower values obtained for the aggressive scale (.66–.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5–35.0% of the variance with the styles of humorous conduct and 13.0–15.0% of the variance with the comic styles. Thus–despite similar labels–these styles of humorous conduct and comic styles differed from the HSQ humor styles. PMID:27547259

Dating violence among college students represents a prevalent and serious problem. An abundance of research has examined risk and protective factors for dating violence, although only recently has research begun to focus on risk and protective factors that could be amenable to change in intervention programs. One potential risk factor for dating violence may be experiential avoidance. Using the Acceptance and Action Questionnaire - II (AAQ-II; Bond et al., 2011), we examined whether experiential avoidance was associated with male perpetrated dating violence after controlling for age, relationship satisfaction, and alcohol use. Within a sample of male college students in a current dating relationship (N = 109) results demonstrated that experiential avoidance was positively associated with psychological, physical, and sexual aggression perpetration, and that it remained associated with psychological and sexual aggression after controlling for age, relationship satisfaction, and alcohol use. The implications of these findings for future research and prevention programs are discussed. PMID:24955326

This article reports the first behavioral genetic study of relationships between alexithymia and four styles of humor: affiliative, self-enhancing, self-defeating, and aggressive. A total of 509 MZ pairs and 264 DZ pairs of twins completed the Toronto Alexithymia Scale-20 (TAS-20) and the Humor Styles Questionnaire (HSQ). Consistent with our predictions, alexithymia correlated negatively with affiliative and self-enhancing humor and positively with self-defeating and aggressive humor. All but one of the 16 phenotypic correlations that we report are significant at the 0.01 level. Also consistent with our predictions, the phenotypic correlations between alexithymia and humor styles were primarily attributable to correlated genetic factors and to a lesser extent to correlated non-shared environmental factors. Correlated shared environmental factors had no significant effect. Implications and limitations of this study are discussed.

2009-01-01

In this study we examine the reliability and validity of students' self-reports about bullying and victimization in schools. 208 5th class students of four "middle schools" in Southern Germany filled in the Bully-Victim-Questionnaire (Olweus, 1989, adapted by Lösel, Bliesener, Averbeck, 1997) and the School Climate Survey (Brockenborough, 2001) to assess the prevalence of bullying/victimization, and to evaluate attitudes towards aggression and support for victims. By using reliability and validity criteria, one third (31%) of the questionnaires was classified as "unreliable/invalid". Mean comparisons of the "unreliable/invalid" group and the "valid" group of the subscales concerning bullying/victimization found significant differences. The "unreliable/invalid" group stated higher values of bullying and victimization. Based on the "unreliable/invalid" questionnaires more students could be identified as bullies/victims or bully-victims. The prevalence of bullying/victimization in the whole sample was reduced if "unreliable/invalid" questionnaires were excluded. The results are discussed in the framework of theories about the presentation of the self ("impression management', "social desirability") and systematic response patterns ("extreme response bias").

Childhood aggression and its resulting consequences inflict a huge burden on affected children, their relatives, teachers, peers and society as a whole. Aggression during childhood rarely occurs in isolation and is correlated with other symptoms of childhood psychopathology. In this paper, we aim to describe and improve the understanding of the co-occurrence of aggression with other forms of childhood psychopathology. We focus on the co-occurrence of aggression and other childhood behavioural and emotional problems, including other externalising problems, attention problems and anxiety-depression. The data were brought together within the EU-ACTION (Aggression in Children: unravelling gene-environment interplay to inform Treatment and InterventiON strategies) project. We analysed the co-occurrence of aggression and other childhood behavioural and emotional problems as a function of the child's age (ages 3 through 16 years), gender, the person rating the behaviour (father, mother or self) and assessment instrument. The data came from six large population-based European cohort studies from the Netherlands (2x), the UK, Finland and Sweden (2x). Multiple assessment instruments, including the Child Behaviour Checklist (CBCL), the Strengths and Difficulties Questionnaire (SDQ) and Multidimensional Peer Nomination Inventory (MPNI), were used. There was a good representation of boys and girls in each age category, with data for 30,523 3- to 4-year-olds (49.5% boys), 20,958 5- to 6-year-olds (49.6% boys), 18,291 7- to 8-year-olds (49.0% boys), 27,218 9- to 10-year-olds (49.4% boys), 18,543 12- to 13-year-olds (48.9% boys) and 10,088 15- to 16-year-olds (46.6% boys). We replicated the well-established gender differences in average aggression scores at most ages for parental ratings. The gender differences decreased with age and were not present for self-reports. Aggression co-occurred with the majority of other behavioural and social problems, from both externalising and internalising domains. At each age, the co-occurrence was particularly prevalent for aggression and oppositional and ADHD-related problems, with correlations of around 0.5 in general. Aggression also showed substantial associations with anxiety-depression and other internalizing symptoms (correlations around 0.4). Co-occurrence for self-reported problems was somewhat higher than for parental reports, but we found neither rater differences, nor differences across assessment instruments in co-occurrence patterns. There were large similarities in co-occurrence patterns across the different European countries. Finally, co-occurrence was generally stable across age and sex, and if any change was observed, it indicated stronger correlations when children grew older. We present an online tool to visualise these associations as a function of rater, gender, instrument and cohort. In addition, we present a description of the full EU-ACTION projects, its first results and the future perspectives.

To assess the effects of gender and parental status of dog owners on knowledge of and attitudes toward factors associated with dog aggression directed toward children. Prevalence survey. 804 dog owners. A questionnaire was distributed to owners of all dogs examined at a university veterinary hospital between January and April 2007. Respondents were asked to indicate whether they agreed or disagreed with 37 statements regarding dog behavior and safety practices for dog-child interactions. Responses were compared between women and men and between parents and nonparents. Of 804 questionnaires that were completed, 421 (52%) were completed by parents and 598 (74%) were completed by women. There was a general lack of knowledge regarding dog behavior and safety practices for dog-child interactions. Women were more knowledgeable than men, regardless of parental status. Mothers were more knowledgeable than fathers and female nonparents regarding interactions with young children and had greater awareness than female nonparents and males (regardless of parental status) regarding interactions with infants and toddlers. Results suggested that dog owners frequently had only limited knowledge of dog behavior and often were unaware of factors that increased the risk of dog bites to children. The veterinary examination presents an important opportunity for education of dog owners regarding dog behavior, including body language, social signals, resource-guarding, and self-defense, and the risks of dog bites to infants and young children.

This study aimed to clarify the characteristics of the Japanese version of the Infant-Toddler Social and Emotional Assessment (J-ITSEA), a parentreport questionnaire concerning social-emotional/behavioral problems and delays in competence in 1- to 3-year-old children. The differences in score between genders, ages, and between the J-ITSEA and the original Infant-Toddler Social and Emotional Assessment were examined. The data of 617 participants recruited from Saitama prefecture through stratified two-stage sampling were analyzed. The Cronbach's alpha ranged from 0.76 to 0.93. Gender differences emerged for some problems and all competence scales, with boys rated higher in the Externalizing problem domain and Activity/Impulsivity subscale and girls rated higher in the Internalizing problem domain, Inhibition to Novelty subscale, and all Competence scales. The Competence domain score increased across age groups. Compared with a normative sample in the US, participants in this study rated higher in Aggression/Defiance and Separation Distress, and rated lower in Peer Aggression and most of the Competence scales. The results indicate that the J-ITSEA scores should be interpreted in comparison with standard scores assigned for gender and 6-month age groups, and that specific criteria for the cut-off points for the J-ITSEA are required instead of those in the original questionnaire.

We sought to combine parental and child reports in order to describe the behavior, self-perception, and emotional profile of children with a surgically corrected congenital heart disease (CHD). Forty-three children with a surgically corrected CHD were selected and compared to an age- and sex-matched healthy group. The parents of the CHD children completed a behavior rating scale, the Child Behavior Checklist. Children 8 years and older (n = 23) completed a self-report questionnaire concerning perceived competence, their anxiety level, and feelings of depression. Compared to parents of healthy children, those of CHD children report significantly lower school results (p < .01), more school problems in general (p < .01), and a higher percentage of their children repeated a school year (p < .01). They also reported more social (p < .01) and attention problems (p < .01) and more aggressive behavior (p < .05). On self-perception and state anxiety questionnaires, no significant differences were found between the patient group and the healthy group. On a depression scale, however, children with a surgically corrected CHD reported more depressive feelings than healthy controls (p < .01). Parents of children with CHD rate their child's school competence to be weaker than healthy peers, they report more attention and social problems and more aggressive behavior. Children themselves did not report differences on perceived competence or anxiety but they do indicate more depressive symptoms than healthy peers.

Extracorporeal membrane oxygenation (ECMO) is increasingly used to save patients with severe cardiopulmonary failure at high risk of dying, but the long-term psychiatric outcome of the treatment has not been studied. Twenty-eight adults who survived ECMO were subjected to psychiatric assessment 5 years after ECMO by means of interviews (MINI-Neuropsychiatric Interview and Montgomery-Åsberg Depression Rating Scale) and psychometrics [Neuroticism and social conformity (EPQ-N+L); General Health Questionnaire (GHQ), Hospital Anxiety Depression Scale; Aggression Questionnaire, Toronto Alexithymia Scale, and Giessener somatic symptom checklist (GBB)]. Fifteen patients (54%) suffered lifetime psychiatric disorders prior to ECMO. After ECMO, 11 subjects (39%) developed new psychiatric disorders, mostly organic mental (18%), obsessive-compulsive disorders (OCD) 15%, and/or post-traumatic stress disorders (PTSD) 11%. These 11 patients reported higher scores on Montgomery-Åsberg Depression Rating Scale (MADRS), GHQ, EPQ-N, and GBB. Disregarding the presence of psychiatric disorders at follow-up, ECMO patients reported high levels of distress, physical aggression, anger, and alexithymic traits. Severe life-threatening cardiovascular or pulmonary failure with subsequent ECMO is associated with an increased prevalence of long-term psychiatric disorders and distress. Studies addressing the etiology and prevalence of psychiatric consequences after ECMO are needed. Copyright © 2013 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

Perceived stress while driving may affect how critical driving events are handled. The current study validates a Chinese version of the Driver Stress Inventory (DSI) and explores its correlation with dangerous driving behaviors and gender. A sample of 246 drivers completed the Chinese version of the DSI and the Driver Behavior Questionnaire (DBQ). We also evaluated specific sociodemographic variables and traffic violations (including speeding, violating traffic signs or markings, driving while intoxicated, running a red light, and incurring penalty points). A confirmatory factor analysis (CFA) verified the DSI's internal structure. The DSI was also validated using questionnaires related to the DBQ, self-reported traffic accidents and violations, and sociodemographic characteristics. First, all of the DSI dimensions were moderately or weakly correlated with the DBQ subscales. Second, aggression, hazard monitoring and fatigue were weakly correlated with minor accidents. Third, drivers who had sped and violated traffic signs during the previous three years reported higher aggression and thrill seeking, while drivers who had violated traffic signs or markings during the previous three years reported decreased hazard monitoring compared with non-offenders. Finally, there were significant gender differences in driver stress. The Chinese version of the DSI will be useful for classifying and diagnosing drivers who may be at an increased risk for stress reactions. Copyright © 2015 Elsevier Ltd. All rights reserved.

2004-12-01

The aim was to study possible relationships between personality traits as measured by the Karolinska Scales of Personality (KSP), a self-report personality inventory based on psychobiological theory, and medical symptoms, in subjects with previous work history in suspected sick buildings. The study comprised 195 participants from 19 consecutive cases of suspected sick buildings, initially collected in 1988-92. In 1998-89, the KSP inventory and a symptoms questionnaire were administered in a postal follow-up study. There were 16 questions on symptoms, including symptoms from the eyes, nose, throat, skin, and headache, tiredness, and a symptom score (SC), ranging from 0 to 16, was calculated. The questionnaire also requested information on personal factors, including age, gender, smoking habits, allergy and diagnosed asthma. The KSP ratings in the study group did not differ from the mean personality scale norm scores, calculated from an external reference group. Females had higher scores for somatic anxiety (P < 0.01), muscular tension (P < 0.001), psychic anxiety (P < 0.01), psychasthenia (P < 0.05), indirect aggression (P < 0.05), and guilt (P < 0.05), while males scored higher on detachment (P < 0.001). Subjects with higher SC were found to display higher degree of somatic anxiety (P < 0.001), muscular tension (P < 0.001), psychic anxiety (P < 0.001), psychasthenia (P < 0.001), inhibition of aggression (P < 0.05), detachment (P < 0.05), suspicion (P < 0.01), indirect aggression (P < 0.01), and verbal aggression (P < 0.05). In addition, ocular, respiratory, dermal, and systemic symptoms (headache and tiredness) were significantly related to anxiety- and aggressivity-related scales. There were associations between personality scales and change of symptom score (SC) during the 9-year period. The associations between KSP personality traits and symptoms were more pronounced in females. In conclusion, there are gender differences in personality and SBS symptoms. Personality may play a role in the occurrence of symptoms studied in indoor environmental epidemiology. Our results support a view that measurement of personality could be of value in future studies and vulnerability to environmental stress. Personality and personal vulnerability should be considered in both indoor environmental epidemiology and practical handling of building with suspected indoor problem, especially when the technical investigations fail to identify any obvious technical malfunction. Moreover, personality aspects should be considered among subjects with possible vulnerable personality exposed to environmental stress, and personality diagnosis can be a complementary tool useful when assessing 'sick building patients' in the medical services. We found no evidence of severe personality pathology in among those working in workplaces with environmental problems so called 'sick buildings'.

Juvenile firesetting behavior has received relatively little research attention and previous attempts to systematically classify this heterogeneous population of children has been only partially successful. Currently there is no literature available that defines treatment and intervention needs of adolescents in residential treatment with problematic firesetting behavior and whether these needs differ from their outpatient cohorts. Data were gathered from a residential (N=17) and outpatient (N=30) sample detailing firesetting history, behavioral functioning, aggression, and personality traits associated with behavioral difficulties. Study subjects were asked to complete the Youth Self Report (Achenbach), Aggression Questionnaire, and Jesness Inventory and to participate in a structured firesetting history interview by project directors. Parents/guardians were asked to complete a Child Behavior Checklist (Achenbach). Adolescents in residential care were significantly more likely to come from a single-parent home, display increased delinquent behaviors, greater depressive symptoms, and report significantly more aggressive thoughts and attitudes than those in outpatient settings. Few differences were found on personality characteristics associated with behavior and conduct problems and few differences were found relative to fire history and firesetting characteristics. Implications for treatment and intervention within a residential setting are discussed as well as factors possibly associated with delaying and/or avoiding initial residential placement.

Objective. Violent dream content and its acting out during rapid eye movement sleep are considered distinctive for rapid eye movement sleep behaviour disorder (RBD). This study reports first quantitative data on dreaming in a cohort of patients with treated Wilson's disease (WD) and in patients with WD with RBD. Methods. Retrospective questionnaires on different dimensions of dreaming and a prospective two-week home dream diary with self-rating of emotions and blinded, categorical rating of content by an external judge. Results. WD patients showed a significantly lower dream word count and very few other differences in dream characteristics compared to age- and sex-matched healthy controls. Compared to WD patients without RBD, patients with WD and RBD reported significantly higher nightmare frequencies and more dreams with violent or aggressive content retrospectively; their prospectively collected dream reports contained significantly more negative emotions and aggression. Conclusions. The reduction in dream length might reflect specific cognitive deficits in WD. The lack of differences regarding dream content might be explained by the established successful WD treatment. RBD in WD had a strong impact on dreaming. In accordance with the current definition of RBD, violent, aggressive dream content seems to be a characteristic of RBD also in WD.

Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

To investigate (1). whether aggressive and delinquent behaviour problems predict subsequent adolescent drinking behaviour; and (2). to what extent this association is mediated by alcohol expectancies and/or peer delinquency/substance use. 147 adolescents (approximately 15 years old) were interviewed with regard to their drinking behaviour. In addition, several self-rating questionnaires were given to gather information regarding the peers of these children. As proposed by the Acquired Preparedness Model (APM), we found that behavioural problems were related to quantity and frequency of alcohol consumed, and that this relationship was mediated by alcohol expectancies. Regarding peer relations, we found positive correlations between drinking behaviour and peer delinquency/substance use, aggression/delinquency and alcohol expectancies. Furthermore, the association between behavioural problems and drinking decreased dramatically if peer delinquency/substance use was accounted for. A hierarchical regression analysis revealed that both alcohol expectancies and peer delinquency/substance use predicted alcohol consumption of adolescents at the 1-year follow-up above and beyond the effects of age, sex, family history of alcoholism and aggression/delinquency of respondents. Alcohol expectancies and peer delinquency/substance use are both crucial to the amount and frequency of adolescent alcohol use. They should be considered in designing prevention and intervention strategies in this age group.

The Relationship Between Humor Styles and Forgiveness

PubMed Central

Hampes, William

2016-01-01

Research has shown that a factor in a victim’s forgiveness of an offender is the victim’s ability to make more positive, or at least less negative, attributions of the offender’s behavior and that perspective-taking can be a factor in facilitating that process. Self-enhancing humor has been found to be positively correlated with perspective-taking empathy and aggressive humor found to be negatively correlated with perspective-taking empathy. Therefore it was predicted that self-enhancing humor would be positively correlated with forgiveness and aggressive humor negatively correlated with forgiveness. The Humor Styles Questionnaire, the Absence of Negative and Presence of Positive subscales of the Forgiveness Scale, and the Forgiveness Likelihood Scale were administered to 112 college undergraduates. Self-enhancing humor was significantly and positively correlated with all of the forgiveness measures, aggressive humor and self-defeating humor were significantly and negatively correlated with some of the forgiveness measures and affiliative humor was not significantly correlated with any of the forgiveness measures. The results were interpreted in terms of previous findings for humor styles, perspective-taking empathy, depression, self-esteem and anxiety. Future research involving the extent to which other personality variables, such as perspective-taking empathy, mediate the relationship between self-enhancing humor and forgiveness was suggested.

Little is known about how safe nurses feel on psychiatric wards across different European countries. This paper is aim to evaluate how ward safety is perceived by ward managers in Great Britain, Germany and Switzerland. We replicated a Swiss questionnaire study in Germany and Britain, which asked ward managers on adult psychiatric wards to give details about their ward including data on the management of aggression, staffing levels, staff training, standards and type of restraint used, alarm devices, treatment and management of aggression and the existence and perceived efficacy of standards (protocols, guidelines). The British sample had by far the highest staffing levels per psychiatric bed, followed by Switzerland and Germany. The British ward managers by far perceived violence and aggression least as a problem on their wards, followed by Germany and then Switzerland. British ward managers are most satisfied with risk management and current practice dealing with violence. German managers were most likely to use fixation and most likely to have specific documentation for coercive measures. Swiss wards were most likely to use non-specific bedrooms for seclusion and carry alarm devices. British wards were far more likely to have protocols and training for the treatment and management of violence, followed by Switzerland and Germany. British ward managers by far perceived violence and aggression to be a small problem on their wards compared with Swiss and German ward managers. This was associated with the availability of control and restraint teams, regular training, clear protocols and a lesser degree risk assessments, but not staffing levels.

Physical and verbal aggression against health professionals, particularly nurses, is globally serious and widespread, with the most vulnerable being nurses working in the Accident and Emergency Department. Most international research into this issue focused on quantifying aggression, describing its nature, identifying perpetrators, stratifying risk and implementing preventive or mitigating interventions. Few studies investigated the nurses' subjective perceptions. As part of the 2016 Italian National Survey on Violence against Accident and Emergency Nurses, our research team collected qualitative data to explore their perceptions of Workplace Violence. From 19th July 2016 to 19th March 2017 we distributed online a 39-item validated questionnaire to 15,618 Emergency Nurses working in 668 Italian National Health Service Accident and Emergency Departments in all 20 Italian Regions. Answers were analysed using van Kaan's method. 1100 Emergency Nurses responded to the survey and 265 replied to our focus question. There were 144 Females, 119 Males, 2 not stated, average age 42 ± 9 years, average work experience 18 ± 9 years, average Accident and Emergency Department experience 11 ± 8 years. Four major themes emerged: the nurses' perception of physical and verbal aggression, precipitating factors, consequences, and solutions. These themes confirmed previous findings and showed that Italian nursing staff's perceptions of physical and verbal aggression is the same as emergency nurses working worldwide. How Italian Accident and Emergency nurses perceive Workplace Violence adds to our knowledge of the issue and contributes to finding shared solutions. Copyright © 2018 Elsevier Ltd.

2017-08-01

The Rock and Water Program (RWP) has been implemented in some Australian schools as a means of addressing school disengagement, anger and aggression, which are significant determinants of mental illness. However, much of the evidence supporting the RWP is anecdotal. This project explored rural adolescent males' perceptions of the RWP. Questionnaires were used to gather data about the students prior to their commencement in the RWP. Focus group interviews were conducted with students at weeks 5 and 9 of the 9-week program. Data were analysed using thematic analysis. The RWP was facilitated in four schools in rural NSW over three terms for a total of 12 program deliveries. One hundred and eighty-seven rural adolescent males participated in the focus groups. The participants were identified by their school as disengaged in schoolwork and either perpetrators and/or victims of anger and aggression. Participants liked the 'learning by doing' action-oriented approach, and reported learning strategies that could reduce aggression in the school and wider community. The focus groups provided insight into why these adolescent boys engaged with this program when generally engagement in school, overall, was reported as poor. Suggestions for program improvement included more or longer sessions, and the inclusion of girls. This study found that the RWP engaged rurally based boys, who spoke positively about the action-oriented program. Future research could examine if this translates into reduced incidents of anger and violence at school and improved school engagement and overall physical and mental health. © 2016 National Rural Health Alliance Inc.

Critical incident exposure in South African emergency services personnel: prevalence and associated mental health issues

2006-01-01

Objectives To assess critical incident exposure among prehospital emergency services personnel in the developing world context of South Africa; and to assess associated mental health consequences. Methods We recruited a representative sample from emergency services in the Western Cape Province, South Africa, to participate in this cross sectional epidemiological study. Questionnaires covered critical incident exposure, general psychopathology, risky alcohol use, symptoms of post‐traumatic stress disorder (PTSD), and psychological and physical aggression between co‐workers. Open ended questions addressed additional stressors. Results Critical incident exposure and rates of general psychopathology were higher than in studies in the developed world. Exposure to critical incidents was associated with general psychopathology, symptoms of PTSD, and with aggression between co‐workers, but not with alcohol use. Ambulance, fire, and sea rescue services had lower general psychopathology scores than traffic police. The sea rescue service also scored lower than traffic police on PTSD and psychological aggression. The defence force had higher rates of exposure to physical assault, and in ambulance services, younger staff were more vulnerable to assault. Women had higher rates of general psychopathology and of exposure to psychological aggression. Other stressors identified included death notification, working conditions, and organisational problems. Conclusions Service organisations should be alert to the possibility that their personnel are experiencing work ‐related mental health and behavioural problems, and should provide appropriate support. Attention should also be given to organisational issues that may add to the stress of incidents. Workplace programmes should support vulnerable groups, and address death notification and appropriate expression of anger. PMID:16498167

Correlates of conflict, power and authority management, aggression and impulse control in the Jamaican population.

The object of this study is to establish the correlates of the phenomenology of conflict and power management in the Jamaican population. A total of 1506 adult individuals were sampled from 2150 households using a stratified sampling method and assessed using the 12 questions of the Jamaica Personality Disorder Inventory (JPDI) on the phenomenology of conflict and power management that are grouped into the psychological features of aggressive social behaviour, unlawful behaviour, socially unacceptable behaviour and financial transgressive behaviour. The database of responses to the demographic and JPDI questionnaires was created and analysed using the Statistical Package for the Social Sciences (SPSS) version 17. Of the national population sampled, 69.1% denied having any phenomenological symptoms of abnormal power management relations while 30.9% of the population admitted to having some degree of conflict and power management, ranging from mild (10.3%), to moderate (17.1), or severe (3.5%). There were 46.55% of the population which had problems with aggressive social behaviour, 9.33% had problems with unlawful behaviour, 9.58% had problems with unacceptable social behaviour and 37.74% had problems with financial transgressive behaviour. Significant gender and socio-economic class patterns for conflict and power management were revealed. This pattern of conflict and power management behaviour is critical in understanding the distinction between normal and abnormal expression of these emotions and actions. Nearly one-third of the sample population ` studied reported problems with conflict, abnormal power and authority management, impulse control and serious aggressive and transgressive behaviour.

A disruption of the oxytocin system seems to affect a variety of brain functions including emotions, mood and social behavior possibly underlying severe social deficits and susceptibility for substance use and mental health disorders. Early life adversity, such as insecure attachment in childhood, has been suggested to influence oxytocin tone contributing to a condition of neurobiological vulnerability. Aim of the present study was to investigate oxytocin serum levels in abstinent heroin addicted patients, in comparison with healthy controls, and the possible correlation with co-occurring psychiatric symptoms, aggressiveness and perception of parental neglect. Eighteen (18) abstinent patients, affected by heroin use disorders, and 18 control subjects, who never used drugs or abused alcohol, were included in the study and submitted to 1) collection of a blood sample for oxytocin assay, 2) Symptoms Check List 90 for psychiatric symptoms evaluation 3) Buss Durkee Hostility Inventory to measure aggressiveness 4) Child Experience of Care and Abuse-Questionnaire to retrospectively test the perception of parental neglect. Heroin exposure extent and heroin dosages were also recorded. Oxytocin serum levels were unexpectedly significantly higher among abstinent patients affected by heroin use disorders and positively correlated with psychiatric symptoms, aggressiveness and mother neglect scores. No correlation was evidenced between oxytocin and heroin exposure extent or dosages. Our findings appear to contradict the simplistic view of oxytocin as a pro-social hormone and confirm previous evidence concerning the peptide levels direct association with aggressive behavior and mood disorders. Considering a more complex mechanism, oxytocin would increase the sensitivity to social salience cues related to contextual or inter-individual factors, promoting pro-sociality in "safe" conditions and, in contrast, inducing more defensive and "anti-social" emotions and behaviors when the social cues are interpreted as "unsafe". This latter condition is often characterizing the clinical history of addicted patients. Copyright © 2017 Elsevier Inc. All rights reserved.

This study investigated the extent to which single mothers of children with atopic eczema experience disease-related stress. A total of 96 mothers were divided into 4 groups: mothers living with a partner, who had or did not have a child with atopic eczema, and single mothers, who had or did not have a child with atopic eczema. The following questionnaires were used to assess psychological burden: Short Stress Questionnaire (Kurzer Fragebogen zur Erfassung von Belastung; KFB), Satisfaction with Life Questionnaire (Fragebogen zur Lebenszufriedenheit; FLZ), General Depression Scale (Allgemeine Depressions-Skala; ADS), and the Questionnaire for Parents of Children with Atopic Eczema (Fragebogen für Eltern von Neurodermitis kranken Kindern; FEN). Single mothers had higher levels of helplessness and aggression due to their child's scratching behaviour than did mothers living with a partner and a child with atopic eczema. Single mothers of children with atopic eczema had the highest scores regarding experienced stress in the family and the lowest scores concerning general life satisfaction. Special care should be provided for single mothers with higher stress, in order to teach them how to deal with the scratching behaviour of their children.

Providing culturally sensitive definitions of child abuse is difficult as perceptions of what constitutes abuse can vary around the world. This study was undertaken to assess how teachers in the Republic of Palau perceived the severity of potentially abusive incidents and what types of recommendations, if any, they would have for situations judged as severely abusive. Attitudes about child rearing practices were also evaluated. Teachers (n = 141 ) were given: (1) a questionnaire consisting of 25 vignettes describing parent/child interactions that were potentially abusive and asked to rate the severity of abuse and recommended interventions for each vignette; and (2) a 40-item parenting styles questionnaires to evaluate attitudes about child-rearing practices. Teachers identified and recommended interventions for more severe forms of abuse at rates similar to other international samples. For less severe parental misconduct, teachers were reluctant to involve nonfamily and outside agencies. Sexual abuse was rated as the most serious type of abuse and when identified, intervention was highly recommended. Some traditional Palauan parenting practices that might be considered maltreatment by other cultures were not considered abusive. For parenting styles, older individuals were more likely to use guilt induction and less likely to use methods of acceptance. Aggressive parenting styles were negatively correlated with all forms of abuse, suggesting that teachers who used aggressive disciplinary styles were less likely to perceive abusive situations as harmful. These results indicate that cultural values and practices play important roles in shaping the definition and interpretation of child maltreatment.

A study on behavioral and emotional problems and competence in children and adolescents in Germany (PAK-KID study) is described. It is the first nationwide representative survey of this kind of children and adolescents aged 4 to 18 years in Germany. For children aged 4 to 10 years the parents completed the German version of Achenbach's Child Behavior Checklist (CBCL 4-18) developed by the Arbeitsgruppe Deutsche Child Behavior Checklist. Children and adolescents aged 11 years and older filled out the German version of the Youth Self-Report that is part of Achenbach's CBCL in addition to the parents completing the German version of the CBCL. A total of 2856 parent questionnaires and 1798 self-report questionnaires completed by children and adolescents were analyzed. The sample was representative with respect to the main sociodemographic variables. On all problem scales children and adolescents aged 11 to 18 years reported significantly more problems than their parents did. The frequency of internalizing problems (social withdrawal, somatic complaints, anxiety/depression) and delinquent behavior of children and adolescents reported by parents increased with the children's age, whereas aggressive behavior and attention problems decreased with age. Girls reported significantly more problems than boys on all internalizing scales of the Youth Self-Report. The effect was not totally replicated in the parent reports. In the parent reports, boys had more attention problems and more aggressive and delinquent behavior than girls.

Mobbing is characterized by the repetition, over a long period of time, of hostile behavior and unethical conduct carried out by a hierarchical superior or co-worker, against someone's physic and mental integrity, endangering one's job or disturbing the work environment. This current investigative study intends to assess the existence, frequency, and intensity of mobbing within the Portuguese nurse population, as well as its impact on their well-being and interpersonal relationships. The study carried out was quantitative, correlational, and cross-sectional. A questionnaire was used as the form to collect data. The questionnaire was sent out to 11 institutions in Portugal which were chosen at random, and it was also made available on a website for whoever wished to respond. The sample was composed of 3,227 nurses from various health institutions in Portugal. From the results obtained it was observed that on average each nurse undergoes 11 aggression conducts in their main place of work. The types of aggression suffered with greater intensity by the victims are communication blockage and being discredited at work. The predominant types of mobbing are the horizontal and the descending type. Nurses suspected the following motivations for those who had perpetrated mobbing against them: envy or jealous, not yielding or having been influenced by blackmail, not being subservient and being innovative, or entrepreneurial in the new work methods or perspectives. Almost half of the victims claim to have had health problems as a result of having suffered mobbing in their workplace.

Earlier use of tobacco in adolescence is associated with numerous adverse outcomes later in life. Although a number of studies have linked individual differences in affective functioning to adolescent smoking, these have relied primarily on self-report measures, and the contribution of different dimensions of affect to the onset of tobacco use during this period remains unclear. The current study examined these issues in a sample of 180 adolescents recruited from an ongoing prospective, longitudinal study examining emotional development. At approximately age 12, participants completed a questionnaire measure of affective temperament and took part in a family interaction task that was coded observationally to provide measures of dysphoric, aggressive, and positive behaviors. At 2 subsequent assessments, which took place approximately 2.5 years and 4 years after the initial assessment, participants completed a questionnaire measure of substance use. In total, 70 participants initiated smoking between the ages of 12 and 17. An earlier onset of smoking was predicted by more aggressive and less positive observed behavior during the interaction task, as well as lower levels of self-reported temperamental Effortful Control. There were no associations between dysphoric behaviors, or temperamental measures of negative affectivity or surgency and the onset of smoking. The findings add to a small body of literature demonstrating that behavioral components of affect can prospectively predict substance use in adolescence and suggest that different dimensions of affect show unique relationships with early substance use.

Procedures are common in pediatric emergency departments and frequently cause distress from pain and/or anxiety. The objective of this study was to describe the incidence, types, and magnitude of long-term behavior changes after procedures in the emergency setting. This is a descriptive pilot study to determine if children display negative behavioral changes after a minor emergency department procedure (abscess drainage or laceration repair). Behavior change was measured at 1 week by telephone follow-up using the 27-item Post Hospitalization Behavior Questionnaire, a well-validated instrument that measures behavior changes across 6 categories: general anxiety, separation anxiety, anxiety about sleep, eating disturbances, aggression toward authority, and apathy/withdrawal. Significant behavior change was defined as 5 or more negative behavior changes on the 27-item questionnaire. Twenty percent of children who underwent abscess drainage (n = 30) and 20% who underwent laceration repair (n = 30) displayed significant negative behavior change at 1 week. Children who displayed significant negative behavior change tended to be younger (3.6 vs 5.9 years) and trended toward being more likely to have received anxiolysis or sedation (16.7% vs 8.3%). Separation anxiety, sleep difficulties, and aggression toward authority were the most common behavior changes. In this pilot study, a significant percentage of children undergoing common emergency procedures exhibited an appreciable burden of negative behavior change at 1 week; these results demonstrate the need for further rigorous investigation of predictors of these changes and interventions, which can ameliorate these changes.

2013-12-05

This exploratory and cross-sectional study aimed to identify the prevalence of bullying in a group of students and analyze the data regarding the gender of those involved in the violence. A questionnaire adapted from Olweus was applied in seven elementary education schools in Portugal. The sample consisted of 387 students between 7 and 14 years old. Data are presented in terms of descriptive statistics and differences between proportions were analyzed using chi-square tests. The gender analysis of victimization and aggression shows that boys and girls are both victims and aggressors, and there are significant differences in involvement in bullying between genders and the roles played. Boys are victims more often when considering different types of bullying, although significant differences were only found for physical aggression. Strategies that include gender roles are a priority for prevention and careful attention to this phenomenon in the school context. The questions addressed contribute to a broader understanding of the phenomenon, emphasizing the differential participation of boys and girls in bullying.

Habituation in acoustic startle reflex: individual differences in personality.

Blanch, Angel; Balada, Ferran; Aluja, Anton

2014-03-01

This study analyzed the relationship of individual differences in personality with habituation in the acoustic startle response (ASR). Data from nine trials in ASR to white noise bursts and a personality questionnaire based on the alternative big five personality approach were modelled with a latent growth curve (LCM) including intercept and slope habituation growth factors. There was a negative correlation between the intercept and slope, indicating that individuals with higher initial ASR levels had also a more pronounced and faster decrease in the ASR. Contrary to expectations, Extraversion and Sensation Seeking did not relate with habituation in ASR. Neuroticism and Aggressiveness related asymmetrically with the habituation rate in ASR. Higher levels of Neuroticism were related with faster habituation, whereas higher levels of Aggressiveness were related with slower habituation. Further studies with the LCM should be undertaken to clarify in a greater extent the association of personality with habituation in ASR. Copyright © 2014 Elsevier B.V. All rights reserved.

2012-06-01

The present study sought to illuminate self-criticism and personal standards dimensions of perfectionism and dependency as specific cognitive-personality vulnerability factors that might contribute to a better understanding of numerous psychosocial problem areas that are relevant to coronary artery disease (CAD). One hundred and twenty-three patients diagnosed with clinically significant CAD completed self-report questionnaires. Zero-order correlations and factor analysis results revealed that self-criticism was primarily related to personality vulnerability (aggression/anger/hostility, Type D negative affectivity) and psychosocial maladjustment (depressive symptoms, worry, avoidant coping, support dissatisfaction), whereas personal standards was primarily related to adaptive coping (problem-focused coping, positive reinterpretation) and dependency was primarily related to worry. Hierarchical regression results demonstrated the incremental utility of self-criticism, personal standards, and dependency in relation to (mal)adjustment over and above aggression/anger/hostility, negative affectivity, and social inhibition. Continued efforts to understand the role of perfectionism dimensions and dependency in CAD appear warranted.

Relationship between achievement goal orientations and the perceived purposes of playing rugby union for professional and amateur players.

2000-08-01

The recent professionalization of rugby union makes it an excellent achievement context in which to examine the relationship between achievement goal orientations and the perceived purposes of sport as a function of competitive standard. During the 1996-97 season, 73 professional and 106 amateur rugby players in England completed a series of questionnaires assessing their achievement goal orientations, beliefs about the purposes of rugby and demographic information. The results of a canonical correlation analysis revealed a conceptually coherent relationship between achievement goal orientations and purposes of rugby. Specifically, a high ego/moderate task orientation was positively related to fitness, aggression and financial remuneration as significant purposes of rugby. Professional players scored higher on those purposes of rugby related to aggression, financial remuneration and fitness, but lower on sportspersonship than amateur players. Professional players also reported higher task and ego goal orientations than amateur players. The findings are discussed in terms of the differences in lifestyle and motivation of professional and amateur rugby union players.

Little work has examined the interrelations among intimate partner violence (IPV), alcohol use, and gambling behavior, and no studies have examined these relationships among males court-ordered to batterer intervention programs (BIPs). The aim of the current investigation was to explore the associations between IPV, alcohol use, and gambling behavior among 341 males court-mandated to attend BIPs utilizing self-report measures. Voluntary, anonymous questionnaires were administered and completed during regularly scheduled BIP sessions. Compared to the general population, a higher percentage of the sample met criteria for pathological gambling (9%), and problem gambling (17%). Further, males exhibiting pathological gambling were more likely to be hazardous drinkers, and hazardous drinkers were more likely to exhibit pathological gambling. Additionally, pathological gamblers were at an increased risk for the perpetration of both physical and sexual aggression. Finally, gambling behavior uniquely predicted the perpetration of sexual aggression above and beyond alcohol use, impulsivity, and relationship satisfaction. The implications of these results for future research and intervention are discussed. PMID:21516369

The role of defense mechanisms in borderline and antisocial personalities.

2010-03-01

We examined whether borderline personality disorder (BPD) and antisocial personality disorder (APD) could be differentiated based on defense mechanisms as measured by observer (Defense-Q; MacGregor, Olson, Presniak, & Davidson, 2008) and self-report (Defense Style Questionnaire; Andrews, Singh, & Bond, 1993) measures. We conducted 2 studies whereby nonclinical participants were divided into borderline and antisocial groups based on scores from the Personality Assessment Inventory (Morey, 1991). Multivariate analysis of variance results revealed significant overall group differences in defense use. Univariate analyses further showed group differences on several individual defenses (e.g., acting out, denial, and turning against self). Together, the findings suggest that in BPD, the defenses may emphasize interpersonal dependency and a tendency to direct aggression toward the self; whereas in APD, the defenses may emphasize egocentricity, interpersonal exploitation, and a tendency to direct aggression toward others. Overall, this study demonstrates important differences in defense use between borderline and antisocial personality groups across both observer and self-report measures.

The Forensic Symptoms Inventory-Revised (FSI-R Adults): Measurement and Structural Invariance Across Gender and Age Groups.

This article investigates the measurement and structural invariance of a newly developed self-report questionnaire, the Forensic Symptoms Inventory-Revised, aimed at measuring eight cognitive, emotional, and behavioral deficits (aggression, lack of social support, problematic substance use, lack of concentration, anger, poor self-regulation, impulsivity, and sexual problems) among adult forensic outpatients. The sample consisted of 716 outpatients (603 males, 113 females) with a mean age of 38.19 (SD = 12.47). Multi-Group Confirmatory Factor Analyses supported the measurement and structural invariance with respect to gender and age groups (18-23 years and ≥24 years). Between-group comparisons revealed that, compared to females, male outpatients reported more substance related problems, as well as incapacities to control verbal and/or physical aggression. Compared to adults, young adults displayed more inadequate self-regulation skills and reported more social support. These findings may promote the formulation of gender- and age-specific treatment goals.

Mechanisms Linking Violence Exposure and School Engagement Among African American Adolescents: Examining the Roles of Psychological Problem Behaviors and Gender

Voisin, Dexter R.; Neilands, Torsten B.; Hunnicutt, Shannon

2010-01-01

This study examines whether the relationship between violence exposure and school engagement is mediated by psychological problem behaviors and whether such relationships are gendered. Five hundred and sixty-three high school African American adolescents (ages 13 to 19 years) completed questionnaires which assessed two types of violence exposure (community violence and marital conflict), psychological problem behaviors (e.g., PTSD symptoms, anxiety, withdrawal, and aggressive behaviors), and school engagement (i.e., student-teacher connectedness and grade point average [GPA] obtained from school records). For male adolescents, psychological problem behaviors collectively mediated the relationship between community violence exposure and student-teacher connectedness. For female adolescents, both community violence and marital conflict exposure were negatively related to both GPA and student-teacher connectedness via aggressive behavior. Findings suggest that the differential impact of type of violence exposure and its sequela based on gender should be considered when addressing low school engagement among African American youth.

Oliveira, Queiti Batista Moreira; de Assis, Simone Gonçalves; Njaine, Kathie; Pires, Thiago Oliveira

2014-03-01

The scope of this paper is to evaluate the perpetration of psychological violence in current male and female dating relationships and their link to psychological violence experienced in other contexts of their lives, namely family, relationships with friends and dating partners. 3,205 students in the 2nd year of high school (15 to 19 years old) in public and private schools in ten Brazilian cities filled out a closed and self-administered questionnaire. The results highlight the fact that the increase in the number of psychologically violent events perpetrated by adolescents in their intimate relationships is related to greater verbal aggression of the mother and father, and the more frequent experiences of psychological violence between parents, siblings, friends and that existing in earlier dating relationships. This reinforces the notion of circularity of psychological violence in various contexts of socialization of adolescents and highlights the continuity of aggressive behavior in other dating relationships, and those between siblings, family and friends.

To compare the outcomes among war veterans who pray/do not pray and who were not suffering mental disorders after the Bosnia-Herzegovina war (1992-95). The sample consists of 100 healthy Bosnian war veterans divided in two equal groups-one, a highly religious group inside which were individuals who perform five obligatory prayers every day, and another group of individuals who do not practice any daily prayer. We used Minnesota Multiphase Personal Inventory (MMPI), Profile Index of Emotions (PIE) and Life Style Questionnaire (LSQ). War veterans who prayed had significantly higher levels for: incorporation, self-protection, and for reactive formation; but significantly lower levels for regression, compensation, transfer, no-controlling, oppositional and aggressiveness than their peers who did not pray. Practicing religion (regular performing daily prayers) is associated with reduction of tendencies towards the tendency for risk, impulsiveness, and aggression. It is also associated with successful overcoming of emotional conflicts in war veterans who practiced religion than their peers who did not practice religion.

While alcohol consumption and heavy episodic (binge) drinking are well-established predictors of male-to-male alcohol-related aggression (MMARA), the role of the father-son relationship in MMARA has yet to be explored. This study therefore examined whether fathering by the biological father rather than another father figure, negative fathering, and gender role modeled by the father figure were significant predictors of involvement in MMARA, once drinking frequency and quantity and heavy episodic drinking were controlled for. A total of 121 university students aged 18 to 25 years (M = 20.63, SD = 1.77 years) voluntarily completed the online questionnaire. The only significant predictors of perpetration of MMARA were a more abusive paternal relationship and drinking quantity (number of standard drinks usually consumed when drinking). Negative father-son relationships may play a role in fostering young men's perpetration of MMARA in the barroom context. Copyright © 2013 by the Research Society on Alcoholism.

A number of studies have reported data suggestive of a significant association between ADHD and BPD, nevertheless, the nature of this relation has not been fully understood yet. In our study, we tried to evaluate if the relationship between retrospectively assessed ADHD symptoms and adult BPD features could mediated by selected temperament/personality traits. Four hundred forty-seven in- and outpatients consecutively admitted to the Clinical Psychology and Psychotherapy Unit of the Scientific Institute H San Raffaele of Milan, Italy, were administered the Italian versions of the following instruments: Structured Clinical Interview for DSM-IV Axis II Personality Disorders, Version 2.0 (SCID-II), Wender Utah Rating Scale (WURS), Temperament and Character Inventory-Revised (TCI-R), Barratt Impulsiveness Scale-11 (BIS-11), and Aggression Questionnaire (AQ). Our mediation analyses showed that the combination of impulsivity, aggression, novelty seeking, and juvenile conduct problems completely mediate the relationship between retrospectively assessed ADHD symptoms and current BPD features.

Dreams enacted during sleepwalking or sleep terrors (SW/ST) may differ from those enacted during rapid eye movement sleep behavior disorder (RBD). Subjects completed aggression, depression, and anxiety questionnaires. The mentations associated with SW/ST and RBD behaviors were collected over their lifetime and on the morning after video polysomnography (PSG). The reports were analyzed for complexity, length, content, setting, bizarreness, and threat. Ninety-one percent of 32 subjects with SW/ST and 87.5% of 24 subjects with RBD remembered an enacted dream (121 dreams in a lifetime and 41 dreams recalled on the morning). These dreams were more complex and less bizarre, with a higher level of aggression in the RBD than in SW/ST subjects. In contrast, we found low aggression, anxiety, and depression scores during the daytime in both groups. As many as 70% of enacted dreams in SW/ST and 60% in RBD involved a threat, but there were more misfortunes and disasters in the SW/ST dreams and more human and animal aggressions in the RBD dreams. The response to these threats differed, as the sleepwalkers mostly fled from a disaster (and 25% fought back when attacked), while 75% of RBD subjects counterattacked when assaulted. The dreams setting included their bedrooms in 42% SW/ST dreams, though this finding was exceptional in the RBD dreams. Different threat simulations and modes of defense seem to play a role during dream-enacted behaviors (e.g., fleeing a disaster during SW/ST, counterattacking a human or animal assault during RBD), paralleling and exacerbating the differences observed between normal dreaming in nonrapid eye movement (NREM) vs rapid eye movement (REM) sleep.

Alpha-methylacyl CoA racemase (AMACR) is an enzyme involved in fatty acids metabolism. One of AMACRs primary substrates, phytanic acid, is principally obtained from dietary red meat/dairy, which are associated with prostate cancer (PCa) risk. AMACR is also a tumor tissue biomarker over-expressed in PCa. In this study, we explored the potential relationship between AMACR polymorphisms, red meat/dairy intake, and PCa risk. Caucasian participants from two population-based PCa case-control studies were included. AMACR single nucleotide polymorphisms (SNPs) were selected to capture variation across the gene and regulatory regions. Red meat and dairy intake was determined from food frequency questionnaires. The odds ratio (OR) of PCa (overall and by disease aggressiveness) was estimated by logistic and polytomous regression. Potential interactions between genotypes and dietary exposures were evaluated. Data from 1,309 cases and 1,267 controls were analyzed. Carriers of the variant T allele (rs2287939) had an OR of 0.81 (95% CI 0.68-0.97) for less aggressive PCa, but no alteration in risk for more aggressive PCa. Red meat consumption was positively associated with PCa risk, and the association was stronger for more aggressive disease (lowest vs. highest tertile OR=1.55, 95% CI 1.10-2.20). No effect modification of AMACR polymorphisms by either dietary red meat or dairy intake on PCa risk was observed. PCa risk varied by level of red meat intake and by one AMACR SNP, but there was no evidence for gene-environment interaction. These findings suggest that the effects of AMACR polymorphisms and red meat and dairy on PCa risk are independent. Copyright © 2010 Wiley-Liss, Inc.

The purpose of this study was to examine the satisfaction of families who participated in the Treatment of Severe Childhood Aggression (TOSCA) study. TOSCA was a randomized clinical trial of psychostimulant plus parent training plus placebo (basic treatment) versus psychostimulant plus parent training plus risperidone (augmented treatment) for children with severe physical aggression, disruptive behavior disorder, and attention-deficit/hyperactivity disorder. Parents completed a standardized Parent Satisfaction Questionnaire (PSQ). Of the 168 families randomized, 150 (89.3%) provided consumer satisfaction data. When they were asked if they would join the study again if they had the option to repeat, 136 (91%) said "yes," 11 (7%) said "maybe," and one (<1%) said "no." When asked if they would recommend the study to other parents with children having similar problems, 147 (98%) said "yes" and 3 (2%) said "maybe." Between 71% (rating one aspect of the Parent Training) and 96% (regarding the diagnostic interview) endorsed study procedures using the most positive response option. Asked if there were certain aspects of the study that they especially liked, 64 (43%) spontaneously reported parent training. Treatment assignment (basic vs. augmented) and responder status were not associated with reported satisfaction. However, responder status was strongly associated with parent confidence in managing present (p<0.001) and future (p<0.005) problem behaviors. These findings indicate high levels of satisfaction with TOSCA study involvement and, taken together with previous pediatric psychopharmacology social validity studies, suggest high levels of support for the research experience. These findings may inform research bioethics and may have implications for deliberations of institutional review boards.

Attitudes and individual difference variables of car and racing enthusiasts regarding high-risk behaviors of street racing and stunt driving have recently been investigated. Positive attitudes toward high-risk driving, personality variables such as driver thrill seeking, and other self-reported risky driving acts were associated with these behaviors. However, probable relationships among high-risk driving tendencies, everyday driving behaviors, and negative road safety outcomes have remained largely unexamined. This study aimed to investigate the associations among car and racing enthusiasts' high-risk driving attitudes, self-reported everyday driving violations (i.e., ordinary and aggressive violations), and self-reported negative outcomes (i.e., collisions and driving offense citations). A web-based survey was conducted with members and visitors of car club and racing websites in Ontario, Canada. Data were obtained from 366 participants. The questionnaire included 4 attitude measures-(1) attitudes toward new penalties for Ontario's Street Racers, Stunt and Aggressive Drivers Legislation; (2) attitudes toward new offenses of stunt driving under the same legislation; (3) general attitudes toward street racing and stunt driving; (4) comparison of street racing with other risky driving behaviors-self-reported driving violations (i.e., ordinary and aggressive violations); self-reported collisions and offense citations; and background and driving questions (e.g., age, driving frequency). Results revealed that attitudes toward stunt driving offenses negatively and general attitudes toward street racing and stunt driving positively predicted ordinary violations, which, in turn, predicted offense citations. Moreover, general attitudes toward street racing and stunt driving positively predicted aggressive violations, which, in turn, predicted offense citations. The findings indicate that positive high-risk driving attitudes may be transferring to driving violations in everyday traffic, which mediates driving offense citations.

The aim of this study was to determine the prevalence of adolescents engaged in cyber-bullying and then to identify whether students involved in cyber- and school bullying present the same characteristics of internalizing problems (insomnia, perceived social disintegration, psychological distress) and externalizing problems (general aggressiveness, antisocial behavior). Semi-structured interviews were conducted with 738 adolescents from a high-school and a middle-school (mean age=14.8 ± 2.7). The Electronic Bullying Questionnaire and the Olweus Bully/Victim Questionnaire were used to identify profiles of cyber-bullying (cyber-victim, cyber-bully, cyber-bully/victim and cyber-neutral) and school bullying (victim, bully, bully/victim and neutral). Internalizing problems were investigated using the Athens Insomnia Scale, a Perceived Social Disintegration Scale and a Psychological Distress Scale. Externalizing problems were assessed using a General Aggressiveness Scale and an Antisocial Behavior Scale. Almost one student in four was involved in cyber-bullying (16.4% as cyber-victim, 4.9% as cyber-bully and 5.6% as cyber-bully/victim); 14% of our sample was engaged in school bullying as a victim, 7.2% as a bully and 2.8% as a bully/victim. The majority of adolescents involved in cyber-bullying were not involved in school bullying. With regard to the problems associated with school bullying, internalizing problems were more prevalent in victims and bully/victims, whereas externalizing problems were more common in bullies and bully/victims. A similar pattern was found in cyber-bullying where internalizing problems were characteristic of cyber-victims and cyber-bully/victims. Insomnia was elevated in the cyber-bully group which is specific to cyberbullying. General aggressiveness and antisocial behavior were more prevalent in cyber-bullies and cyber-bully/victims. Looking at the differences between types of bullying, victims of "school only" and "school and cyber" bullying had higher scores for insomnia and perceived social disintegration than victims of "cyber only" bullying or students "non-involved". Higher general aggressiveness scores were observed for "school only" bullies and "school and cyber" bullies than for bullies in "cyber only" bullying or students "non-involved". Regarding antisocial behavior, "school only" bullies, "cyber only" bullies, "school and cyber" bullies had higher scores than students "non-involved". This study highlights the importance of investigating both school and cyber-bullying as many psychosocial problems are linked to these two specific and highly prevalent forms of bullying.

Personality is considered as an important aspect that can affect symptoms and social function in persons with schizophrenia. The personality questionnaire Swedish universities Scales of Personality (SSP) has not previously been used in psychotic disorder. To investigate if SSP has a similar internal consistency and factor structure in a psychosis population as among healthy controls and if patients with psychotic disorders differ from non-psychotic individuals in their responses to the SSP. Patients with psychotic disorders (n = 107) and healthy controls (n = 119) completed SSP. SSP scores were analyzed for internal consistency and case-control differences by Cronbach's alfa and multiple analysis of covariance, respectively. Internal consistencies among patients were overall similar to that of controls. The patients scored significantly higher in seven (Somatic trait anxiety, Psychic trait anxiety, Stress susceptibility, Lack of assertiveness, Detachment, Embitterment, Mistrust) and lower in three (Physical trait aggression, Verbal trait aggression, Adventure seeking) of the 13 scales of the inventory. In three scales (Impulsiveness, Social desirability and Trait irritability) there was no significant difference between the scoring of patients and healthy controls. The reliability estimates suggest that SSP can be used by patients with psychotic disorders in stable remission. Patients score higher on neuroticism-related scales and lower on aggression-related scales than controls, which is in accordance with earlier studies where other personality inventories were used.

The relationship between gender-related personality traits, on one hand and drinking, permissiveness towards drinking, and social as well as personal problems associated to drinking on the other, was studied in a general population sample from the City of Morelia, Mexico. Four gender-related traits scales were used for measuring assertive and aggressive masculinity and affective and submissive feminity, in addition to a standardized questionnaire for assessing drinking and other associated behavior. Some of the main results showed that people with high scores in affective feminity were less willing to allow drinking. Men who adopted a submissive feminine role and women with high masculine aggressive scores were more permissive as regards drinking. Among men, assertive masculine and affective feminine traits were more characteristic among those who drank than among abtainers. Drinking among women was related to liberal attitudes towards drinking and to aggressive masculinity. As regards the number of drinks consumed per month, assertive masculinity and liberal attitudes among men and affective feminity and liberal attitudes among women predicted the number of drinks. Affective feminity was negatively related to drinking. Regarding drinking-associated problems, frequency of drunkenness and submissive feminity among males predicted greater personal and social problems. Among women, drunkenness frequency and number of drinks were the most significant predictors. Contrary to what has been found in other countries, gender was a better drinking predictor than gender-related personality traits.

This multi-center observational study investigated the prevalence of agitation in newly hospitalized schizophrenia patients in China and its potential risk factors. It was performed in 2014 and covered 14 hospitals. Newly hospitalized patients with schizophrenia or suspected schizophrenia who met the diagnostic criteria of the International Statistical Classification of Diseases and Related Health Problems, 10th revision, were recruited. Agitation and related risk factors were evaluated by a questionnaire designed for the survey. General demographic data, disease characteristics, scores on schizophrenia rating scales and agitation rating scales (e.g., Positive and Negative Syndrome Scale-Excited Component [PANSS-EC] and Behavioral Activity Rating Scale [BARS]) were collected. Among the 1512 patients screened in the study, 1400 (92.59%) were eligible. According to the PANSS-EC and BARS, the prevalence of agitation was 60.92% (853 of 1400) and 59.00% (826 of 1400), respectively. The overall prevalence of agitation was 47.50% (665 of 1400). The most important risk factor of agitation was being aggressive at baseline (Modified Overt Aggression Scale score ≥4, odds ratio=6.54; 95% confidence interval=4.93-8.69). Other risk factors included a history of aggressive behavior, northern region of residence, involuntary hospitalization, disease severity, low level of education, living alone, being unemployed or retired.

In the Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation (COURAGE) trial, some patients with stable ischemic heart disease randomized to optimal medical therapy (OMT) crossed over to early revascularization. The predictors and outcomes of patients who crossed over from OMT to revascularization are unknown. We compared characteristics of OMT patients who did and did not undergo revascularization within 12 months and created a Cox regression model to identify predictors of early revascularization. Patients' health status was measured with the Seattle Angina Questionnaire. To quantify the potential consequences of initiating OMT without percutaneous coronary intervention, we compared the outcomes of crossover patients with a matched cohort randomized to immediate percutaneous coronary intervention. Among 1148 patients randomized to OMT, 185 (16.1%) underwent early revascularization. Patient characteristics independently associated with early revascularization were worse baseline Seattle Angina Questionnaire scores and healthcare system. Among 156 OMT patients undergoing early revascularization matched to 156 patients randomized to percutaneous coronary intervention, rates of mortality (hazard ratio=0.51 [0.13-2.1]) and nonfatal myocardial infarction (hazard ratio=1.9 [0.75-4.6]) were similar, as were 1-year Seattle Angina Questionnaire scores. OMT patients, however, experienced worse health status over the initial year of treatment and more unstable angina admissions (hazard ratio=2.8 [1.1-7.5]). Among COURAGE patients assigned to OMT alone, patients' angina, dissatisfaction with their current treatment, and, to a lesser extent, their health system were associated with early revascularization. Because early crossover was not associated with an increase in irreversible ischemic events or impaired 12-month health status, these findings support an initial trial of OMT in stable ischemic heart disease with close follow-up of the most symptomatic patients.

To evaluate the relationship between the Mandarin acceptable noise level (ANL) and the personality trait for normal-hearing adults. Eighty-five Mandarin speakers, aged from 21 to 27, participated in this study. ANL materials and the Eysenck Personality Questionnaire (EPQ) questionnaire were used to test the acceptable noise level and the personality trait for normal-hearing subjects. SPSS 17.0 was used to analyze the results. ANL were (7.8 ± 2.9) dB in normal hearing participants. The P and N scores in EPQ were significantly correlated with ANL (r = 0.284 and 0.318, P < 0.01). No significant correlations were found between ANL and E and L scores (r = -0.036 and -.167, P > 0.05). Listeners with higher ANL were more likely to be eccentric, hostile, aggressive, and instabe, no ANL differences were found in listeners who were different in introvert-extravert or lying.

Alcohol expectancies likely play a role in people's perceptions of alcohol-involved sexual violence. However, no appropriate measure exists to examine this link comprehensively. The aim of this research was to develop an alcohol expectancy measure which captures young adults' beliefs about alcohol's role in sexual aggression and victimization. Two cross-sectional samples of young Australian adults (18-25 years) were recruited for scale development (Phase 1) and scale validation (Phase 2). In Phase 1, participants (N = 201; 38.3% males) completed an online survey with an initial pool of alcohol expectancy items stated in terms of three targets (self, men, women) to identify the scale's factor structure and most effective items. A revised alcohol expectancy scale was then administered online to 322 young adults (39.6% males) in Phase 2. To assess the predictive, convergent, and discriminant validity of the scale, participants also completed established measures of personality, social desirability, alcohol use, general and context-specific alcohol expectancies, and impulsiveness. Principal axis factoring (Phase 1) and confirmatory factor analysis (Phase 2) resulted in a target-equivalent five-factor structure for the final 66-item Drinking Expectancy Sexual Vulnerabilities Questionnaire (DESV-Q). The factors were labeled (1) Sexual Coercion, (2) Sexual Vulnerability, (3) Confidence, (4) Self-Centeredness, and (5) Negative Cognitive and Behavioral Changes. The measure demonstrated effective items, high internal consistency, and satisfactory predictive, convergent, and discriminant validity. The DESV-Q is a purpose-specific instrument that could be used in future research to elucidate people's attributions for alcohol-involved sexual aggression and victimization.

Cocaine consumption can induce transient psychotic symptoms, which has been correlated with more severe addiction and aggressive behavior. However, little is known about the nature of the relationship between personality traits and psychotic symptoms in cocaine-dependent patients. This study examined the relationship between neuroticism and cocaine-induced psychosis. A total of 231 cocaine-dependent patients seeking treatment were recruited to the study. Personality was evaluated by the Zuckerman-Kuhlman Personality Questionnaire. Cocaine-induced psychosis questionnaire, SCID-I, and SCID-II were used to evaluate comorbidity and clinical characteristics. Data analysis was performed in three steps: descriptive, bivariate, and multivariate analyses. Cocaine-induced psychosis was reported in 65.4% of the patients and some personality disorder in 46.8%. Two personality dimensions (Neuroticism-Anxiety and Aggression-Hostility) presented a significant effect on the risk of experiencing psychotic symptoms (t(229) = 2.69, p = 0.008; t(229) = 2.06, p = 0.004), and patients with psychotic symptoms showed higher scores in both variables. On the multivariate analysis, only Neuroticism remained as a significant personality factor independently associated with psychotic symptoms (Wald = 7.44, p<0.05, OR = 1.08, CI 95% 1.02-1.16) after controlling for age, gender and number of consumption substances. An association between high neuroticism scores and presence of psychotic symptoms induced by cocaine has been found, independently of other consumption variables. Personality dimensions should be evaluated in cocaine-dependent patients in order to detect high scores of neuroticism and warn patients about the risk of developing cocaine-induced psychotic symptoms.

Associations between impulsivity, aggression, and suicide in Chinese college students

2014-01-01

Background Although there are accumulating data regarding the epidemiology of suicide in China, there are meager data on suicidal ideation and attempts among college students. Interestingly, elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, the objective of this research was to identify the associations between suicide and the personality factors of impulsivity and aggression. Methods This study’s sampling method employed stratified random cluster sampling. A multi-stage stratified sampling procedure was used to select participants (n = 5,245). We conducted structured interviews regarding a range of socio-demographic characteristics and suicidal morbidity. The Patient Health Questionnaire depression module (PHQ-9) was used to acquire the information about thoughts of being better off dead or hurting themselves in some ways during the past two weeks. The impulsivity symptoms in this study were assessed with the BIS-11-CH (i.e., the Chinese version of the BIS-11), and the Aggressive symptoms were assessed with the BAQ. The statistical package for social science (SPSS) v.13.0 program (SPSS Inc., Chicago, IL, USA) was used for statistical analysis. Socio-demographic variables such as ethnic and gender were compared between groups, through the use of χ2 tests. The nonparametric test (k Independent Sample test, Kruskal-Wallis H) was performed to determine differences between the personality factors of impulsivity and aggression and suicide. Results In total, 9.1% (n = 479) of the 5,245 students reported they have ever thought about committing suicide; and 1% (n = 51) reported a history of attempted suicide (attempters). The analyses detected significant differences in scores on cognitive impulsivity (p < 0.01), when comparing individuals who only had suicidal ideation and individuals who had attempted suicide. Moreover, significant differences were found between ideators only and attempters on scores of self-oriented attack (p < .001). Conclusions Suicidal ideation is prevalent among Chinese university students. Students with high aggression scores were more susceptible to committing suicide. Scores on self-oriented attack and cognitive impulsivity may be important factors for differentially predicting suicide ideation and suicide attempts. PMID:24894449

Screen time, defined as time spent watching television, DVDs, or videos or playing computer or video games, has been related to serious health consequences in children, such as impaired language acquisition, violent behaviour, tobacco smoking and obesity. Our aim was to determine if a simple intervention aimed at preschool-aged children, applied at the health maintenance visits, in the primary care setting, would be effective in reducing screen time. We used a two group randomized controlled trial design. Two- to 6-year-old children and their parents were randomly assigned to receive an intervention to reduce their screen time, BMI and parental report of aggressive behaviour. At the end of the intervention we made home visits at 2, 6 and 9 months and the parents completed questionnaire. Parents in the intervention group reported less screen time and less aggressive behaviour than those in the control group but there were no differences in BMI z scores. This study shows that a preschool-based intervention can lead to reductions in young children's television/video viewing. © 2014 John Wiley & Sons Ltd.

To investigate the presence of cyberbullying among Greek students and the efficacy of proposed preventive interventions. Three types of high schools (private, experimental and public) with different politics on on-line aggression were enrolled. All students of the aforementioned schools were asked to complete an anonymous questionnaire. Around 62 % of the high school students experienced cyberbullying by electronic means, especially by cell phone, mostly the public school students (p 0.008). The bully was a stranger in more than 40 % of the cases. Over 60 % of the victims had not seeked help but dealt with the attack on their own. Only 20 % of the victims manifested sleep or eating disorders, physical/ psychological symptoms or changes in their social life as a consequence of the cyber-attack. Cyberbullying is a usual phenomenon among high school students. The bully is frequently unacquainted to the victim. Most of the victims are not physically or psychologically affected by the cyber-attack and do not share the event with anyone. There was a slight difference in the response of the students to cyberbullying among the different school politics of on-line aggression.

Optimizing Efficiency of Psychopathology Assessment through Quantitative Modeling: Development of a Brief Form of the Externalizing Spectrum Inventory

Patrick, Christopher J.; Kramer, Mark D.; Krueger, Robert F.; Markon, Kristian E.

2014-01-01

The Externalizing Spectrum Inventory (ESI; Krueger, Markon, Patrick, Benning, & Kramer, 2007) provides for integrated, hierarchical assessment of a broad range of problem behaviors and traits in the domain of deficient impulse control. The ESI assesses traits and problems in this domain through 23 lower-order facet scales organized around three higher-order dimensions, reflecting general disinhibition, callous-aggression, and substance abuse. The full-form ESI contains 415 items, and a shorter form would be useful for questionnaire screening studies or multi-domain research protocols. The current work employed item response theory and structural modeling methods to create a 160-item brief form (ESI-bf) that provides for efficient measurement of the ESI’s lower-order facets and quantification of its higher-order dimensions either as scale-based factors or as item-based composites. The ESI-bf is recommended for use in research on psychological or neurobiological correlates of problems such as risk-taking, delinquency, aggression, and substance abuse, and studies of general and specific mechanisms that give rise to problems of these kinds.

Gwee, K P; Lim, L E C; Woo, M

2002-01-01

To our knowledge, this is the first paper that examines the sexual profile of rapists in Singapore. A semi-structured interview based on a questionnaire about sexual habits was conducted on 62 convicted rapists and a control group of 63 prisoners comprising 32 convicted for violent non-sexual offences and 31 for non-violent non-sexual offences. Significantly more rapists masturbated at least once a month and were exposed to pornography within six months before the offence when compared to non-violent controls. Violent controls did not differ significantly from rapists in any aspect of the sexual history. The greater similarity between rapists and violent controls lends support to the concept of rape as a violent rather than sexual offence. A subgroup of 17 'hypersexual' rapists were identified who were either having sex or masturbating very frequently but had still resorted to rape. Compared to the other 46 rapists, the 'hypersexual' rapists were more likely to have fantasised predominantly about rape or bondage and to cite domination, aggression or hostility as reasons for committing rape, suggesting an even stronger element of power and aggression than in their less sexually active counterparts.

Video game use has been associated with several behavioral and health outcomes for adolescents. The aim of the current study was to assess the relationship between parental co-play of video games and behavioral and family outcomes. Participants consisted of 287 adolescents and their parents who completed a number of video game-, behavioral-, and family-related questionnaires as part of a wider study. Most constructs included child, mother, and father reports. At the bivariate level, time spent playing video games was associated with several negative outcomes, including heightened internalizing and aggressive behavior and lowered prosocial behavior. However, co-playing video games with parents was associated with decreased levels of internalizing and aggressive behaviors, and heightened prosocial behavior for girls only. Co-playing video games was also marginally related to parent-child connectedness for girls, even after controlling for age-inappropriate games played with parents. This is the first study to show positive associations for co-playing video games between girls and their parents. Copyright © 2011 Society for Adolescent Health and Medicine.

Background Adolescent juvenile offenders are at high risk for problems associated with drug use, including polysubstance use (i.e., use of a variety of drugs). The combination of juvenile offending and polysubstance use presents a significant public and child health concern. Objective This study explored polysubstance use among a sample of youth incarcerated for serious offenses. We examined several risk factors for substance use and delinquency (i.e., early and frequent substance use, prior history of arrests, school expulsion, Black ethnicity), as well as the association between aggression and polysubstance use. Methods Data were collected via questionnaires from 373 serious male juvenile offenders upon intake into a secure locked facility. Youth were on average 16 years old, and minority youth were overrepresented (28.1% Black, 53.1% Latino). Poisson regressions were used to assess the associations between the risk factors, aggression, and polysubstance use. Results Consistent with the literature, Black youth reported less polysubstance use and later age of drug use onset than White and Latino youth. Findings suggest that Latino juvenile offenders and those with an early and problematic pattern of substance use are at heightened risk for polysubstance use. Aggression was not significantly related to polysubstance use, over and above the risk factors. Conclusions Given that Latino youth experience low rates of treatment for substance use, the development of culturally-sensitive interventions for these youth is needed. Interventions should also be multifaceted to address the multitude of risk factors associated with polysubstance use among juvenile offenders. PMID:26997851

Health providers, particularly nurses, are at high risk for aggression in the workplace. This phenomenon, constantly increasing, it can undermine the resilience of the health providers, increasing the burn-out and staff turnover. Highlight the frequency and characteristics of violence in different health areas. A questionnaire, the "Violent Incident Form" (VIF), was administered to 987 nurses belonging to various hospitals and emergency services of Modena. The data, divided into three groups related to health areas of origin, the emergency department, medical-surgical and psychiatric wards, grouped by risk of such violence and work characteristics, were compared with each other. 74% of respondents have suffered at least one episode of violence in the last 3 years, with the highest percentage in psychiatric area (84%). In the general hospital (64%) and in the emergency department (54%), violence was mostly verbal, acted out by patients and by members of their family, while, in psychiatric wards, has been frequently physical (40%) or physical and verbal (33%), made especially from patients with the highest number of physical consequences, never reported to the Court. Only 31% of nurses expected the attack. This study confirms, in accordance with the literature, that the aggression toward the nurses are a remarkable phenomenon, and it suggests that, to prevent such a violence, are necessary not only precautions and a structural organization, specific for the different health areas, but above all, great awareness and preparation from the health providers around this risk.

To examine stress reactivity in a sample of adolescents with prenatal drug exposure (PDE) by examining the consequences of PDE on stress-related adrenocortical reactivity, behavioral problems, and drug experimentation during adolescence. Participants (76 PDE, 61 non-drug exposed [NE]; 99% African-American; 50% male; mean age = 14.17 yr, SD = 1.17) provided a urine sample, completed a drug use questionnaire, and provided saliva samples (later assayed for cortisol) before and after a mild laboratory stress task. Caregivers completed the Behavior Assessment System for Children, Second Edition (BASC II) and reported their relationship to the adolescent. The NE group was more likely to exhibit task-related cortisol reactivity compared to the PDE group. Overall behavior problems and drug experimentation were comparable across groups with no differences between PDE and NE groups. In unadjusted mediation analyses, cortisol reactivity mediated the association between PDE and BASC II aggression scores (95% bootstrap confidence interval [CI], 0.04-4.28), externalizing problems scores (95% bootstrap CI, 0.03-4.50), and drug experimentation (95% bootstrap CI, 0.001-0.54). The associations remain with the inclusion of gender as a covariate but not when age is included. Findings support and expand current research in cortisol reactivity and PDE by demonstrating that cortisol reactivity attenuates the association between PDE and behavioral problems (aggression) and drug experimentation. If replicated, PDE may have long-lasting effects on stress-sensitive physiological mechanisms associated with behavioral problems (aggression) and drug experimentation in adolescence.

Higher testosterone levels have been positively related to a variety of social behaviors and personality traits associated with intrasexual competition. The aim of this study was to evaluate the role of testosterone levels and personality traits such as aggressiveness, competitiveness, and self-esteem on the task of choosing a fighting competitor (a rival) with or without a motivation to fight. In Study 1, a group of 119 men participated in a task for choosing a rival through pictures of men with high-dominant masculinity versus low-dominant masculinity. Participants completed three personality questionnaires and donated two saliva samples (pre-test and post-test sample) to quantify their testosterone levels. We found that the probability of choosing high-dominant masculine men as rivals increased with higher aggressiveness scores. In Study 2, the task of choosing rivals was accompanied by motivations to fight (pictures of women with high or low waist-to-hip ratio [WHR]). In this context, we observed that the probability of choosing dominant masculine men as rivals depended on the WHR of the women. Overall, average levels of post-test testosterone, aggressiveness, and high self-esteem increased the probability to fight for women with low WHR independently of the dominance masculinity of the rivals. Our results indicate that human decisions, in the context of intrasexual competition and mate choice, are regulated by physiological and psychological mechanisms allowing men to increase their biological fitness. We discuss our results in the light of the plasticity of human behavior according to biological and environmental forces.
