Prevalence and determinants of aggressive behavior among adults with problematic substance use in Northwest Ethiopia: a cross-sectional survey

BackgroundThe recent WHO data reported that a high treatment gap for behavioral illnesses (70%) in low- and- middle-income countries and the mortality rate of aggressive behavior reaches up to 32.1 per 100,000 populations in the region. However, the magnitude of aggressive behavior is not well stated in resource-limited settings. Therefore, the aim of this study was to assess the prevalence and determinant factors of aggressive behavior among adults with problematic substance use in northwest Ethiopia.MethodsA community-based cross-sectional study was employed from January to March 2019. A multi-stage cluster sampling method was used to screen a total of 4028 adults for problematic substance use by using the Cutdown, Annoyed, Guilty, and Eye-opener questionnaire (CAGE AID). Finally, 838 participants were positive for problematic substance use and interviewed for aggressive behavior using a modified overt aggression scale. Multiple logistic regression analysis was used to show the adjusted odds ratios (AOR) and p-value < 0.05 considered statistically significant. A multilevel binary logistic regressions model was employed for the hierarchical structure of two-level data for the individual and woreda/district levels.ResultsThe prevalence of aggressive behavior was found to be 37.9% (301/795, 95% CI: 34.5, 41.3). Stressful life events (AOR = 2.209, 95 CI; 1.423, 3.429), family history of mental illness (AOR = 4.038, 95 CI; 2.046, 7.971), comorbid physical illness (AOR = 2.01, 95 CI; 1.332, 3.032) and depressive symptoms (AOR = 2.342, 95 CI; 1.686, 3.253) were associated with aggressive behavior among individual with problem substance use.ConclusionAggressive behavior was found to be high among problematic substance uses. An individual with problematic substance use is recommended to be screened by health extension workers for aggressive behavior at the community level.

Underlying Familial Factors for Aggressive Behavior in Romantic Relationships: A Systematic Review.

Aggressive behavior in romantic relationship has serious effects, including both intra- and inter-personal issues. Aggressive behaviors in romantic relationships have been linked to underlying familial problems. While there have been previous reviews that studied on many interpersonal and dyadic implications of aggressive behavior in romantic relationships, there is nonetheless a lack of studies on the various components of familial factors for aggressive behavior in romantic relationships. The databases Scopus, MEDLINE, Google Scholar, and SAGE Journals were used to search for terms that are related to familial factors (family factor, family support, family relationship) as well as terms related to aggressive behavior in romantic relationships (aggression in romantic relationship, violence in intimate relationship). The articles considered for this review were original studies, samples, or subsamples of males or females who reported any underlying familial factors in childhood or adulthood that contributed to aggressive behavior in romantic relationship, and the studies must be written in English. This review has 27 papers that met the inclusion criteria. The findings from this review revealed the presence of inconsistent conclusions between familial factors and aggressive behavior in romantic relationships, with some studies failing to establish such links. These findings are reviewed with regards to the existing gaps in the literature as well as potential research options.

Current Problems of Preventing Aggressive Behavior in the Educational Environment: A Case Study of Three Schools in the Russian Countryside

Among the most acute socio-pedagogical problems facing the modern Russian school is the increasing number of aggressive manifestations in the educational environment. This situation actualizes the schools need for the prevention and correction of aggressive behavior. The article presents the results of a socio-pedagogical research, the purpose of which was to identify the types and forms of aggressive behavior in the educational environment and to explore the current state of preventive work. The study was conducted by the Institute for the Study of Childhood, Family and Upbringing in July 2021 in the form of a questionnaire survey of directors of educational organizations. The methodology of the research included a socio-pedagogical analysis of situations of aggressive manifestations among students, teachers and parents; study of social, environmental, family and personal factors of aggressive behavior; and identification of mechanisms for preventing aggressive behavior in the educational environment. The results are presented in the format of socio-psychological portraits of three schools located in the countryside, which are prominent representatives of Russian rural society. The study made it possible to draw the following main conclusions: (1) preventive work becomes an independent type of pedagogical work; (2) cyber-aggression, which was actively manifested during the period of distance learning and now requires comprehensive preventive work with students, teachers, and parents, is an over-pressing problem for educational organizations; (3) todays school is faced with the urgent task of developing and implementing programs for the prevention and correction of aggressive behavior. The ideas presented in the article can be used in the practice of educational organizations of different types.

Molecular Signatures of Chromosomal Instability Correlate With Copy Number Variation Patterns and Patient Outcome in IDH-Mutant and IDH-Wildtype Astrocytomas.

Chromosomal instability due to mutations in genes guarding the stability of the genome is a well-known mechanism underlying tumorigenesis and malignant progression in numerous cancers. The effect of this process in gliomas is mostly unknown with relatively little research examining the effects of chromosomal instability on patient outcome and therapeutic efficacy, although studies have shown that overall/total copy number variation (CNV) is elevated in higher histologic grades and in cases with more rapid progression and shorter patient survival. Herein, we examine a 70-gene mRNA expression signature (CIN70), which has been previously shown to correlate tightly with chromosomal instability, in 2 independent cohorts of IDH-mutant astrocytomas (total n = 241), IDH-wildtype astrocytomas (n = 228), and oligodendrogliomas (n = 128). Our results show that CIN70 expression levels correlate with total CNV, as well as higher grade, progression-free survival, and overall survival in both IDH-mutant and IDH-wildtype astrocytomas. In oligodendrogliomas, these mRNA signatures correlate with total CNV but not consistently with clinical outcome. These data suggest that chromosomal instability is an underlying factor in aggressive behavior and progression of a subset of diffuse astrocytomas. In addition, chromosomal instability may in part explain the poor response of diffuse gliomas to treatment and may serve as a future therapeutic target.

Comparative Analysis of Indicators of the Early Stages of Sensory and Sensorimotor Information Processing in Aggressive and Nonaggressive Schizophrenia Patients

Objective. To study the characteristics of the early stages of sensory (inhibition of the P50 event-related potential) and sensorimotor (prestimulus modification of the acoustic startle reaction (ASR)) information processing in patients with schizophrenia taking account of their behavioral characteristics. Materials and methods. Two groups of patients were investigated using oculography and electroencephalography: aggressive patients (group A, 44 subjects) and nonaggressive patients (group NA, 27 subjects); a control group of 48 healthy subjects were also studied. Patients’ mental status was assessed on the PANSS. Results and conclusions. These studies identified features characteristic of schizophrenia patients, particularly increases in the latent period of ASR, deficiency of prestimulus inhibition (PSI) (with delay intervals of 60 msec), and inhibition of P50 relative to normal. The aggressivity factor influenced the lateralized features of these deviations in ASR only in group A. Group NA showed an increase in baseline ASR amplitude and a decrease in prestimulus ASR amplitude. Analysis of P50 showed a significant increase in amplitude and a decrease in latency in responses to the second stimulus in group NA. A significant increase on the G14 scale (Poor impulse control) and the nature of its correlation with ASR and P50 measures in group A suggested that increased impulsivity was an important factor in aggressive behavior in the cohort of patients studied here. The characteristics of ASR and P50 typical of group NA provided evidence of increased sensitivity to external stimuli, which may be associated with personality features inhibiting aggression. These results led to the conclusion that measures of the early stages of information processing can be regarded as potential predictors of aggressive behavior in schizophrenia patients.

The Role of Personality Traits and Situational Factors as Determinants of Aggression

Background: Over the years, different explanations have been given for the difference between personality traits and situational factors regarding how they affect our behavior. The present study investigates the role of personality traits versus situational factors in aggressive behavior. Objective: The purpose of this research was to examine whether situations in which participants are made to feel angry are more powerful than personality traits in determining aggressive behavior. Methods: Forty-eight women students from Qatar University (M= 21.73, SD=4.43) completed the 200-item ZKA Personality Questionnaire, which measures aggressiveness, neuroticism, activity, extraversion and sensation-seeking, and the 7-item trait anger scale from the Buss-Perry Aggression Questionnaire (BPAQ). Following an experimental situation that triggered anger by an interpersonal insult, the participants were randomly assigned to an anger-induced group (experimental condition) or a nonanger-induced group (control condition). Afterwards, the participants completed the hot sauce paradigm to assess aggressive behavior. Results: The results showed a significant difference between the anger and nonanger groups regarding aggressive behavior. However, no significant correlation was found between any facets of the personality questionnaire or the trait anger scale and aggressive behavior. Conclusion: Situational influence is more powerful than personality traits and trait anger in determining aggressive behavior. These findings are discussed based on the debate addressing the influence of situational or person-specific traits in determining actual behavior.

Система соціально-психологічних чинників конфліктної поведінки сучасної молоді в медіа-просторі

In the article, on the basis of the general law of cultural development, a dynamic model of the Internet as a social and psychological object is formulated, a conceptual apparatus of research is formalized and definitions of social and psychological factors of youth aggressive behavior on the Internet and socio-psychological predisposing factors of aggressive behavior are introduced. The purpose of the article is theoretical analysis and substantiation of social and psychological factors of youth aggressive behavior on the Internet. To achieve this goal, it is necessary to solve the following main research objectives: to analyze and develop a dynamic model of the development of the Internet as an object of social and psychological research; formalize ideas about social and psychological factors of youth aggressive behavior on the Internet; to identify and substantiate the socio-psychological factors of youth aggressive behavior on the Internet and to classify them. The methodology of the work is based on the general genetic law of cultural development and the systematic general representation of cyberspace by the youth. The classification and main socio-psychological factors of youth aggressive behavior on the Internet were developed: predisposing factors (personal and cyberspace environments) and situational factors (factors reflecting the objective and subjective components of the social virtual situation). It is shown that the field of application of the results is training programs for reducing the aggressive behavior of young people in cyberspace. The problem of researching the system of social and psychological factors that determine the aggressive behavior of young people on the Internet has highlighted the urgent task - substantiation of social and psychological factors of aggressive behavior of young people on the Internet.

Assessment of aggressive behavior among preparatory school children in Tanta City

Background and aim School violence and aggression have become an increasing concern to public health professionals, clinicians, policy makers, educators, and the general public. It is a multidimensional problem with biological, psychological, social, and environmental roots. The purpose of this study was to assess the prevalence of aggressive behavior and to explore the associated psychosocial risk factors among preparatory school children. Patients and methods A multistage stratified sample of 380 students of both sexes, 12–15 years old, was collected from the preparatory schools at Tanta City through the academic year 2016–2017. Aggressive behavior was assessed by Modified Overt Aggression Scale. Arabic version of Kiddie Schedule for Affective Disorders and Schizophrenia − Present and Lifetime Version was applied to assess current and past episodes of psychopathology in children and adolescents who had high scores of aggression. Results Overall, 23.7% of the studied sample had aggression, and it was distributed as follows: 0.8% of the sample scored high on aggression scale, 5.5% moderate, 7.4% mild, and 10% minimal. Risk factors of aggressive behavior included male sex; second child of the family; smoking; drug addiction; watching action movies; history of physical abuse; no hobbies or playing sports; widowed or divorced parent; poor relationships with parents, friends, and teachers; living in extended families; family history of psychiatric illness; low socioeconomic class; a drug-addict family member; physical abuse in the family; unfavorable school atmosphere; and history of dropping class. Overall, 8.9% of aggressive students had attention-deficit hyperactivity disorder, 6.7% had conduct disorder, 6.7% had depression, 3.3% had oppositional defiant disorder, and 1.1% had substance use disorder. Conclusion School aggression and violence is a frequent and a multifaceted problem among the school adolescents.

The review of modern researches of psychogenetic factors of aggressive behavior

The review covers urgent domestic and foreign researches of psychogenetic factors of aggressive behavior. The authors consider cytogenetic mechanisms providing mental activity and behavioural activity of the person, offer the concept of the control system of information coding, and specify features of a genotype-environmental interaction in forming aggressive behavior. Classification of forms of aggression is given. Approaches to interpretation of this concept are considered. The theories explaining the nature of aggression (J. Dollard and L. Berkowitz’s frustration theory, A. Bandura’s theory of social learning, K. Lorentz and S. Freud’s theory of instinctual drives, biological theory) are analyzed.The brain mechanisms underlying different forms of aggressive behavior are described.A large number of domestic and foreign studies devoted to the problem of genetic determination of mental processes and behavior is analyzed. The authors bring forward the review of researches of genetic foundations of aggressive behavior. They describe approaches recognized insolvent today (the extra Y-chromosome theory, the “genesign” system, the “generalist genes” concept) and offer conceptions confirmed today: the role of monoamine neuromodulators (the interrelation between various forms of aggressive behavior and neurotransmitter systems of the brain), testosterone is described; the influence of the social-economic status and the environmental factors is considered. The available psychogenetic data is described from the point of view of the additive model of development. On the whole, they note a polygenic nature of the inheritance of aggression (the genes coding information of the olfactory, hormonal, mediator systems are biological factors of aggression).Perspectives of the development of this research area are outlined: the bioinformation analysis of molecular mechanisms of activity of the central nervous system by means of studying the expression of genes in brain cells; the review of the first results obtained by means of this method is offered.

Psychiatrists’ View on the Risk Factors for Aggressive Behavior in Psychotic Patients

In meta-analytic studies it was found that patients diagnosed with a psychotic disorder are at increased risk for displaying violent behavior. However, it remains largely unclear which specific factors contribute to the heightened risk for aggression in this patient group, nor what the views of psychiatrists are on this issue. A cross-sectional survey study was carried out and a survey questionnaire was developed to investigate the view of 652 psychiatrists on the relative contributions of various factors (e.g., illness related, personality, social influences) that might explain aggression in psychosis. It was found that psychiatrists generally view illness-related features as the most important determinant of aggression in these patients, followed by impulsivity/lack of insight and social influences, whereas personality characteristics are considered as least relevant. Latent class cluster analysis revealed that there are several subgroups of psychiatrists who attach different levels of importance to various types of risk factors. In these subgroups, two cluster contrasts were found: one representing differences in response style, and one representing differences in the evaluation of personality characteristics. Overall, psychiatrists seem to adopt a medical model when interpreting aggression in psychotic patients, although several subgroups of psychiatrists can be identified who have different opinions of such behavior.

Asymmetrical frontal resting-state beta oscillations predict trait aggressive tendencies and behavioral inhibition

Asymmetrical patterns of frontal cortical activity have been implicated in the development and expression of aggressive behavior. Along with individual motivational tendencies, the ability to restrain one's impulses might be a factor in aggressive behavior. Recently, a role for the inhibitory cortical beta rhythm was suggested. The present study investigated whether individual differences in resting state asymmetries in the beta frequency band were associated with trait aggression and behavioral inhibition. In addition, the selective contributions of the prefrontal and motor cortex areas to these associations were examined. Results showed that relative dominant right frontal beta frequency activity was associated with both heightened trait aggression, especially hostility, and reduced response inhibition. Moreover, asymmetries over the anterior electrode locations proved to be related most closely to trait aggression, while asymmetries over the central electrode locations were associated with response inhibition. Together these findings show that right-dominant frontal beta activity is positively associated with aggressive tendencies and reduced behavioral inhibition.

Risk Factors for Aggressive Behavior Among Psychiatric Inpatients

The evaluation of a patient's potential for aggressive behavior is an important component of care on psychiatric units. In this study, the aggressive behavior of 111 new psychiatric inpatients in Taiwan was recorded by nursing staff using the Overt Aggression Scale (OAS) during the patients' hospitalization. Psychiatrists made diagnoses in accordance with DSM-IV criteria and collected information about psychosocial risk factors for aggression. On average, aggressive patients were hospitalized longer than nonaggressive patients. After duration of hospitalization was controlled for, it was found that patients with an earlier onset of illness were more likely to be aggressive than other patients.

The Relationship of Functional Variables and Psychopathology to Aggressive Behavior in Persons With Severe and Profound Mental Retardation

A number of hypotheses have emerged regarding the etiology of physical aggression in persons with mental retardation. Although a multicomponent model is appropriate, results of functional analysis-based studies have yielded promising results in identifying instigating and maintaining factors of aggression. However, the relationship between functional variables and conditions such as psychiatric diagnosis to aggressive behavior has yet to be investigated in persons with mental retardation. We conducted a study examining the prevalence of environmental or physical factors in aggressive behavior in mentally retarded persons with and without psychiatric disturbance. One hundred and thirty-five individuals with mental retardation who exhibited physical aggression were assessed with the Questions About Behavior Function Scale (QABF) to identify environmental or physical contribution to aggressive behavior. One or more behavioral functions were identified for 75% of the participants. Additionally, of 66 of the participants scoring above the clinical cutoff on an assessment for dual diagnosis, 75% met criteria for an environmental or physical function for aggression. No significant differences in number of participants with an identifiable function of aggression were found between the no dual diagnosis and dual diagnosis groups. Our findings underscore the importance of identifying functions underlying aggressive behavior in persons with mental retardation, and the need to consider functional variables regardless of psychiatric condition in treatment planning efforts for such individuals.

Neurobiological Factors in Aggressive Behavior

The author's aim was to review literature in the neurosciences and psychiatric clinical research reports about biological factors in aggression and the pathophysiological mechanisms that accompany aggression in neuropsychiatric syndromes. Studies were located through computer searches of relevant experimental reports and review articles mainly from the last 25 years. Several studies using neuroimaging and neurophysiological and neuropathological research techniques have identified lesions in the limbic structures, temporal lobes, and frontal lobes of the brain in abnormally aggressive individuals. Several reports have associated deficiency or dysregulation of serotonin with homicidal, suicidal, and impulsive behavior. However, few studies have focused on polypeptides or second messenger systems, although abnormalities in these systems have been reported in patients with neuropsychiatric syndromes who have shown aggressive behavior. Even fewer studies focus on the correlation of brain structures and metabolic markers. The understanding of aggressive behavior in psychiatric patients is fragmented. Some explanations are speculative and extrapolated to clinical psychiatric syndromes from experimental data on the neurophysiology of cats, rats, and other mammals. Identification of biochemical markers that can be used in predicting patients' response to pharmacological interventions may be the next step in developing more rational treatment of violent patients.
