Particularities of Offenders Imprisoned for Domestic Violence from Social and Psychiatric Medical-Legal Perspectives.

Background and Objectives: It is known that there may be an interconditionality between social status, personality disorders, and aggressive behavior. This study aimed to analyze the social and psychiatric diagnosis characteristics in subjects imprisoned for domestic violence acts compared to other types of aggressive behaviors. Materials and Methods: We performed a retrospective study using psychiatric medical–legal reports at the National Institute of Legal Medicine “Mina Minovici” Bucharest from 2016 to 2020. Results: We included 234 cases in our analysis, from which 132 (56%) were domestic violence offenders (DVO), and 102 (44%) were violence offenders imprisoned for other aggressions (OVO). Overall, DVOs were older than OVOs (43.0 +/− 14.7 vs. 36.1 +/− 16.6 years-old). In both study groups, most subjects were men, but the DVO group had more women than the OVO group: 23 cases (17%) and 3 cases (3%), respectively. In 14 cases (11%), previous criminal records were found from the DVO and 31 (30%) from the OVO group. Significantly fewer DVO were chronic psychoactive substance users: 83 (63%) in the DVO group versus 78 (86%) in the OVO group. Significantly more DVO had suicidal tendencies 26 (20%) compared to OVO 9 (9%). DVO subjects had significantly less often unsocialized conduct disorder or antisocial personality disorder compared to the OVO group. Conclusions: We found that DVO, compared to the OVO, were more numerous, older, less abusive, with a less frequent history of psychoactive substance abuse and addictions, and were less frequently indifferent to the committed acts.

Longitudinal Links of Individual and Collective Morality with Adolescents\u2019 Peer Aggression

Adolescents’ aggressive behavior has been often linked to biases in morality. However, limited knowledge is available regarding the relative strength of different moral correlates, both at the individual and class-level, in predicting different types of aggressive behavior over time. To address this gap, the present study tested the prospective associations of moral identity and moral disengagement with reactive and proactive aggression in a short-term longitudinal study. The sample consisted of 1158 Italian adolescents (48.7% females; Mage = 13.6 years, SD = 1.1). Participants completed self-report measures of moral identity, moral disengagement, perceived collective moral disengagement in the fall, and reactive and proactive aggression in the fall and in the spring. Multivariate multilevel analysis indicated that, at the individual level, after controlling for the stability of aggressive behavior, T2 (Time 2) reactive aggression was higher for students who reported lower moral identity and higher moral disengagement at T1 (Time 1). For proactive aggression, a significant interaction effect indicated that the negative association between T1 moral identity and T2 aggression was apparent only at high levels of T1 moral disengagement. Moreover, proactive aggression was significantly predicted by higher perceived collective moral disengagement. At the class-level, T1 collective moral disengagement helped explain between-class variability of T2 reactive and proactive aggressive behavior. How these results expand previous research on morality and aggressive behavior and their potential implications for prevention and intervention programs is discussed.

Sex Differences in How Territory Quality Affects Aggression in Convict Cichlids.

SynopsisIn animal contests, the value an individual assigns to limited resources can directly impact the level of aggression it demonstrates. For territorial species, individuals often assess their territory quality and appropriately modify the time and energy invested in its defense. In this study, male and female convict cichlids, Amatitlania nigrofasciata, were acclimated to one of three territorial treatments representing either a low, medium, or high resource value. Territories with a “Low Value” included substrate alone, “Medium Value” territories included substrate and a nest site, and a “High Value” territory included substrate, a nest site, and constant food source. After three days of acclimation, a size-matched intruder was introduced to elicit territorial aggression and behaviors were observed. Territory quality affected one measure of low-intensity aggression (displays) in residents but had no effect on high-intensity aggression (bites and chases). Moreover, there was a significant effect of sex, with males and females differing in the types of aggressive behaviors demonstrated across all treatments. Females showed more low-intensity aggressive behaviors toward intruders than males did. Additionally, a significant interaction of sex and territory quality was observed on two measures of high-intensity aggressive behavior (bites and chases), with females more likely than males to increase aggressive behaviors along with increasing territory quality. This suggests that females may be more sensitive and/or responsive to changes in the quality of a territory, possibly due to the necessity of a suitable nest site for egg deposition within a territory.

Communicative Cyberpersonality Types of Aggressive Behaviour as a Cross-Cultural Phenomenon

The paper deals with communicative cyberpersonality types of aggressive behaviour as a cross-cultural phenomenon. The aim of the article is to distinguish and differentiate communicative cyberpersonality types of aggressive behaviour ssupported by such characteristics of the communicative cyberspace as globalism, virtuality, and anonymity. The relevance of the current investigation is determined by a constantly growing role of computer-madiated communication in a modern person’s life, by the appearance of new types of the Internet users’ interaction, by the display a communicative personality’s new qualities and by the necessity of giving a scientific background to all these appearing and changing phenomena. The analysed material comprises dictionary definitions and modern Russian an English texts selected by the continuous sampling method from different Internet genres, such as forums, blogs, social nets, web-chats, which reflect destructive speech products. The overall number of investigated material is 600 units. The material is analysed using such methods as introspection, conceptual modelling, interpretative analysis and contextual analysis. The analysed material shows that not any naming means of aggressive behaviour in a cyberspace can become a name for a communicative personality type. Communicative personality type should be distinguished on the clear lexicographical representation underlying the concept, its own communicative intensions, definitely chosen communicative strategies and tactics, certain modality and verbal and non-verbal means. Taking into consideration these characteristics one can distinguish the following communicative cyberpersonality types of aggressive behaviour: troll, holy war maker, hater, cyberbuller/cyberbully (cybermobber), shamer (blamer), griefer, cyberstalker.

Cyberbullying. Bullying and antisocial behavior among Chilean adolescents

Cyberbullying is a phenomenon that affects teenagers around the globe. Studies suggest that it has a negative impact on both victims and aggressors, becoming a public health concern. Previous studies have sought to define its predictors; however, most studies have not assessed the relationship between cyberbullying and traditional bullying or other types of aggression. Herein, we aimed to assess the association between antisocial behaviors and traditional bullying as forms of aggression that could predict cyberbullying in victims and perpetrators. A total of 791 adolescents from Santiago, Chile, were included in our study; mean age of 13.57 years old, 46.06% female. We used the structural equations model to test our model. Our results show a good fit of the model, showing a relation between antisocial behaviors and bullying, but only for the perpetrator. Bullies were associated with the roles of cyberbullying victim and cyberbullying perpetrator. Bullying victims were only associated with cyberbullying victims. Our results confirm the relation between different types of aggressive behavior, particularly for perpetrators, which could account for a unique dynamic for bullying and cyberbullying perpetrators. Prevention programs should explore more comprehensive interventions aimed at adolescents and promote a better understanding of this type of aggression.

Impact of A Mobile Health Intervention On Bullying Among Children: A Systematic Review

Bullying is an anti-social behavior carried out by individuals or type of aggressive behavior that contains intentional aspects to dominate and hurt others and caused negative impact on the victim's physical and psychological. Imbalance of strength, whether physical, age, and social status, which is done repeatedly by one or several children against other children is a characteristic of bullying behavior. This study aimed to evaluate the effectiveness of mHealth on bullying among children. The studies using PRISMA and searched in four databases that published between 2016 until 2020. Twelve articles found were used in this systematic review that contains about an antibullying program that involves several parties has the preventive efforts in cases of bullying. A majority of interventions can be used in bullying and also be used as promotive and preventive efforts in cases of bullying in schools and communities.

Nurses’ Perceptions regarding Types of Aggressive Behaviour displayed by Patients in a Selected Psychiatric Hospital in Lesotho

Aggressive behaviour of inpatients in mental health facilities occurs globally and is a serious nursing problem. Consequently, there is insufficient research studies conducted among nurses regarding the types of aggressive behaviour displayed by patients in psychiatric institutions. The purpose of this study was to determine nurses’ perceptions regarding the types of aggressive behaviour displayed by patients in a selected psychiatric hospital in Lesotho. A quantitative descriptive survey was used to collect data from 119 nurses who were selected by quota sampling. The data were collected by means of a self-administered questionnaire, analysed by using SPSS (version 25), and displayed by using tables, frequencies, standard deviations, means and Pearson’s chi-square test. The findings reported that the types of aggressive behaviour included verbal aggression (86%, n = 103), physical aggression against objects (79%, n = 94), physical aggression against self (65.5%, n = 78), and physical aggression against other people (81.5%, n = 97). This study concludes that the perceptions of the nurses were positively inclined towards violent behaviour displayed by patients. The study recommends that nurses be equipped with comprehensive psychiatric skills and information to enable them to manage and cope with patients’ aggression.

Are psychopathic traits predictive of conduct problems and aggression when other risk factors are considered? A longitudinal test among Croatian children

PurposeTo examine prognostic and incremental values of grandiose-deceitful interpersonal style, callous-unemotional traits and impulsivity-need for stimulation, and their ability to predict conduct problems and different types of aggressive behavior above and beyond well-established risk factors, including early childhood hyperactivity, aggression, and parenting styles in a community sample of very young children. MethodsUsing data from the ECLAT study, a 5-year prospective/longitudinal study of 175 elementary school children in Croatia (80 boys/95 girls; MFirst_assessment = 5.28 years and MLast_assessment = 10.33 years), hierarchical regression analyses were conducted to evaluate the utility of children's psychopathy features. ResultsAnalyses revealed that, after controlling for individual and parenting risk factors at age 5, only impulsivity-need for stimulation was an independent, albeit weak, predictor of conduct problems at age 10, but not aggression. In addition, the multidimensional child psychopathy construct (i.e., high levels on all three psychopathic traits) at age 5 in combination with concurrent conduct problems was the strongest predictor of future negative outcomes above and beyond other risk factors, but only of conduct problems. ConclusionsAfter both individual and parenting factors are taken into account, psychopathic traits individually have limited usefulness when predicting future antisocial behavior but may be important in prediction when all three psychopathic traits are elevated and co-occur with conduct problems in a community sample of young children.

A substantia innominata-midbrain circuit controls a general aggressive response

Although aggressive behaviors are universal and essential for survival, "uncontrollable" and abnormal aggressive behaviors in animals or humans may have severe adverse consequences or social costs. Neural circuits regulating specific forms of aggression under defined conditions have been described, but how brain circuits govern a general aggressive response remains unknown. Here, we found that posterior substantia innominata (pSI) neurons responded to several aggression-provoking cues with the graded activity of differential dynamics, predicting the aggressive state and the topography of aggression in mice. Activation of pSI neurons projecting to the periaqueductal gray (PAG) increased aggressive arousal and robustly initiated/promoted all the types of aggressive behavior examined in an activity-level-dependent manner. Inactivation of the pSI circuit largely blocked diverse aggressive behaviors but not mating. By encoding a general aggressive response, the pSI-PAG circuit universally drives multiple aggressive behaviors and may provide a potential target for alleviating human pathological aggression.

Aggressive Behaviors of Adult Male Atlantic Spotted Dolphins: Making Signals Count during Intraspecific and Interspecific Conflicts

Some species exhibit behavioral plasticity by altering their aggressive behavior based on their opponent. Atlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the northern Bahamas. We examined whether groups of adult male spotted dolphins demonstrated behavioral plasticity during two different types of aggressive interactions. We described and compared the types of aggressive behaviors used during intraspecific aggression and interspecific aggression with bottlenose dolphins. Between the years 1991-2004, twenty-two aggressive encounters (11 intraspecific (spotted only), 11 interspecific (spotted vs. bottlenose)) were behaviorally analyzed. Twenty-three specific aggressive Behavioral Events, further grouped into three Behavioral Types, were examined throughout these encounters. Similarities and differences in the use of the Behavioral Types occurred during intra- and interspecific aggression. Groups of male Atlantic spotted dolphins altered their behavior during aggressive encounters with male bottlenose dolphins. Spotted dolphins increased their use of the Pursuit Behavioral Type and did not use the Display Behavioral Type significantly more than the Contact Behavioral Type during interspecific aggression. The increased use of a more overt and energy intensive Behavioral Type, Pursuit, suggests that Atlantic spotted dolphins altered their behavior during aggressive encounters with bottlenose dolphins to compensate during fights with a larger species and/or to effectively communicate with a different species.

Measuring Bullying in Russian Schools: Prevalence, Age and Gender Correlates, and Associations with School Climate

This article describes the process of developing instruments to measure school bullying and school climate characteristics as well as presents the results of their evaluation on a sample of 871 middle- and high-school students from a Russian megalopolis. It is shown that bullying prevalence depends on the type of aggressive behavior and involvement, varying from 4% (involvement in physical bullying as a victim or perpetrator) to 45% (involvement in verbal bullying as a bystander). Most often, students get involved in bullying as witnesses, but the number of victims and bullies is not significantly lower. On average, 28% of school students initiate bullying and 33% get bullied once or twice a month. Occasional bullying is more typical of girls, while boys are more likely to bully their peers frequently. Middle-school students (seventh and eighth grades) are at the highest risk of being exposed to bullying in all roles. Four aspects of school climate are also analyzed, all of them being significantly negatively related to bullying involvement (regardless of the type of bullying or respondent’s role in a bullying incident).

Patterning types of aggressive behaviour of primary school children with speech disorders

In order to understand the relationship between speech disorders and aggressive behaviour, the dependence of aggressive behaviour in young school-age children on their speech disorders was studied experimentally. The study had 286 children (6 to 10 years old), 57% of them with typical psychophysical development and 43% with speech disorders in Ukrainian schools. According to the results of the summary of the scientific methods, there have been discoveries of three types of aggression and six subtypes of aggression and also their features: the self-regulating type of aggression incorporates the controlled and the competitive subtypes; covert type – defensive and depressive; behavioural type – demonstrative and physical. The findings indicate that the more complex the speech disorder is, the greater the manifestation of depressive, demonstrative and physical aggression is. The more complex the state of aggression is, the harder it is to realize it. A child cannot always overcome such states on his/her own; therefore, he/she needs co-education, adult assistance.

Patient aggression toward dentists

BackgroundWorkplace violence toward health care professionals is both widespread and widely overlooked. Only 4 studies of aggression toward dentists have been published—none in the United States—with the prevalence of aggression ranging from 29% through 80%. The purpose of this study was to provide an initial estimate of rates of patient aggression in dental practices in the United States. MethodsThe authors surveyed 98 dentists recruited from the faculty and alumni network of a college of dentistry. Participants completed a confidential online survey assessing whether they had experienced any of 21 specific types of aggressive behaviors from their patients. ResultsPast-year aggression prevalence was 22.2%, 55.0%, and 44.4% for physical, verbal, and reputational aggression, respectively. Career prevalence was 45.5%, 74.0%, and 68.7% for physical, verbal, and reputational aggression, respectively. Rates did not differ by sex, race, ethnicity, specialty, age, years practicing, or average number of patients treated per day. ConclusionsParticipants reported levels of physical, verbal, and reputational aggression at rates comparable with those of other health care professionals in the United States and abroad. Additional research with larger representative samples of dentists in the United States is necessary to confirm these prevalence estimates. Future research should also investigate predictors and outcomes of patient aggression and prevention and intervention strategies. Practical ImplicationsSubstantial rates of patient aggression highlight the need to address this problem in dental practices. The authors discuss implications for the dental profession, including proactive steps that could be taken to reduce patient aggression in dental offices.

Short-term sequences of aggressive behavior in psychiatric inpatients with psychotic disorders using Markov models

Background Aggression in inpatients with psychotic disorders is harmful to patients and health care professionals. Aims The current study introduces a novel approach for assessing short-term sequences of different types of aggression. Methods Occurrence and type of aggressive behavior was assessed retrospectively by reviewing hospital charts in a sample of 120 inpatients with psychotic disorders, admitted to the psychiatric wards of an academic hospital using the Modified Overt Aggression Scale (MOAS). Behavioral sequences of verbal aggression, physical aggression against objects, physical aggression against oneself and physical aggression against others were analyzed by using Markov models, a statistical technique providing the probabilities of transferring from one state to another. Results The Markov models showed that when patients behave aggressively, they are likely to either show the same type of aggression or to be non-aggressive consecutively. Patients are, however, unlikely to subsequently show another type of aggression. Non-aggressive behavior is very unlikely to result in physical aggression or aggression against objects. Conclusion The current study introduced a novel approach on how to investigate aggressive behavior in patients with psychotic disorders. Replication of our results in a bigger sample is needed to reliably develop a day-to-day risk assessment tool for aggressive behavior.

Вызывающее оппозиционное расстройство в детском и подростковом возрасте

Oppositional defiant disorder (ODD) and conduct disorder (CD), which usually develop at the age below 18, are considered as a sustainable antisocial and aggressive types of behavior, stepping beyond the borders of socially accepted standards. Within the recent decades, significant success has been achieved in the diagnosis and long-term predictive assessment of different types of behavioral aberrations, occurring during the childhood and adolescence. Early development of behavioral disorders forms unfavorable predictions and correlates with biological and social risk factors, such as attention deficit, impulse control disorder and unfavorable social environment. Most of the clinical observations confirm the effectiveness of different psychotherapeutic programs in the therapy of ODD/CD. The drug treatment is proposed to be used only in the severe cases, or in the cases when psychotherapeutic methods are not effective.

Altruistic and Aggressive Types of Behaviorin a Nonzero-Sum Positional Differential Gameof Three Persons

In this paper, the results of the author’s previous work concerning a nonzero-sum positional differential game of two persons with different types of the players’ behavior are extended to a game of three persons. For simplicity, the paradoxical type of behavior is not used by the players. The notions of altruistic and aggressive behavior types are generalized. As in the two-person game, it is assumed that each player chooses not only a positional strategy but also an indicator program function. The rules for forming controls for each triple of behavior types and the definition of a BT-solution are clarified. An example of a game with the dynamics of simple motion on a plane and a phase constraint is considered. It is assumed that the players can show altruism and aggression towards their partners, and the case of simultaneous aggression from all the players is not excluded. A description of BT-solutions of the game is given.

Diagnóstico de indicadores de violencia escolar en adolescentes

The adolescent manifests a set of interests that, through school violence, make up behavioral and emotional conflicts in the course of development and social adjustment, therefore, the description and measurement of the main types of violence projects a danger in school areas, especially due to the normalization of such aggressiveness. Objective: to diagnose the type of aggressive behavior of adolescents aged 12 to 15 years, through screening tests, thus integrating focus groups within an institutionalized educational framework, through a study quantitative type of descriptive-transversal cut, not experimental. Methodology: To achieve the objective, various evaluation techniques were used, the first was Resolution and perspective of school violence conflict, followed by the Instrument for School Harassment and Violence (AVE), which based the diagnosis phase in an analyzed sample of n = 568 students. Contribution: the high level of parenting neglect could be identified, as well as the deterioration of self-concept, suicidal ideas and lack of attachment to parental figures.

Sleep quality and bullying - prevalence in a cohort of Portuguese students.

The involvement of adolescents in violent behaviors is becoming an important public health problem that is concerning physicians as it is associated with a decrease in adult life quality. In this context, bullying is a type of aggressive behavior that occurs repeatedly in interpersonal relationship where power imbalance exists increasing the risk of physical and psychosocial problems in all its intervenient. Prevalence of bullying in Portuguese adolescents is estimated to be ranging from 16.2 to 27.5%. Sleep disorders are a well-known problem related to bullying situations, either as a consequence or a risk factor; estimated prevalence in adolescence is 25% worldwide. In the present study we aimed to investigate the association between sleep quality and the involvement in school bullying in Portuguese adolescents in two high schools. Data collected from a cross-sectional survey addressing questions on bullying behaviors and sleep quality was analyzed using SPSS 22.0. A two-tailed p-value of less than 0.05 was considered significant for alltests. We have included 171 adolescents, mean age of 14.39±1.149 years, 59.6% were boys; prevalence of bullying behaviors was 28.1%. Among the students 15.2% were identified as "pure victims", 8.8% as "pure bullies", 4.1% as "bully-victims" and 71.9% as "neutrals". "Pure bullies" and "bully-victims" present higher Athens Insomina Scale (AIS) scores (p=0.004) and higher prevalence of insomnia (p=0.004). The prevalence of insomnia was significantly higher in the group involved in bullying behaviors comparing with the neutrals (58.3% vs 30%, p=0.001). We verified that 65.4% of the reported bullying situations took place inside the school and 8.8% of those teachers did nothing to help the victim and in 17.5% school staff took the same attitude. We found a prevalence of bullying behaviors higher than the one reported in previous studies and a prevalence of insomnia of 38.0%, proving that bullying and sleep disturbances are two major problems in adolescence which may increase future risk for psychiatric symptoms, involvement in criminal activities, hyperactive, and inattentive behaviors. We verified a strong relation between insomnia and involvement in bullying situations with those who are involved reporting difficulties in sleep induction. The group of "bully-victims" was identified as potentially being the one with the most troubled adolescents since they combine characteristics of both bullies and victims. The authors conclude that there should be an investment in school-based interventions that help recognize and reduce school bullying and change lifestyle behaviors that may negatively influence adolescents' development.
