Introduction: Antisocial Personality Disorder (ASPD) is characterized by a pervasive pattern of disregard for and violation of the rights of others, typically emerging by age 15 years and involving behaviors such as deceitfulness, impulsivity, and aggressiveness. The present study sought to examine the prevalence of the comorbid ASPD in adult people with Alcohol Dependence Syndrome (ADS) and identify clinical characteristics associated with ASPD. Methods: A cross-sectional study of 100 consecutive subjects diagnosed with ADS was conducted. Subjects were examined between August 2023 and September 2023. Various assessments and questionnaires were employed, including the Montreal Cognitive Assessment (MoCA), Alcohol Use Disorders Identification Test (AUDIT), and Structured Clinical Interview for DSM-IV (SCIDII). A computed tomography (CT) scan of the brain was performed on 47.5% participants. Results: Out of the 100 individuals screened for the study, 20 were excluded. The study found that 35% of the examined study participants had a comorbid ASPD. Individuals with both ADS and ASPD were more likely to be younger, started drinking at an earlier age, had higher hospitalization rates, and scored higher on the AUDIT test (all P < 0.05%). Also, they had lower education levels, higher rates of unemployment, and lower marriage rates (all P < 0.05%). In addition, they reported more family members with ADS, incarceration, or mental illness and a higher frequency of traumatic experiences (all P < 0.05%). Depression, anxiety, stress (all P < 0.05%), and sleep problems (P = 0.058) were correlated with ASPD. Participants with the comorbid ASPD had lower MoCA scores (P = 0.046) and struggled with attention and linguistic subtests compared to subjects with ADS only. Conclusion: The study highlights the high prevalence of comorbid ASPD in participants with ADS, shedding light on their demographic and psychometric characteristics. Individuals with the comorbid ASPD are more likely to face cognitive deficits, especially in linguistic and attention-related tasks. The findings underline the importance of considering the comorbidity of ASPD in ADS subjects. The study implies that the understanding of the associated risk factors can aid in developing more targeted treatment interventions. [ABSTRACT FROM AUTHOR]

Psychoanalytically informed therapeutic communities constitute an important, but often forgotten, chapter in the history of applied psychoanalysis. Apart from the original experiments by analysts and educators such as August Aichhorn or Homer Lane, little is known about the vibrant and socially progressive nature of residential communities established during and in the aftermath of the Second World War. This article explores the uses of psychoanalysis in four such communities that worked with antisocial children and young people: the Hawkspur Camp, established in 1936 by David Wills and Marjorie Franklin; the Barns Hostel, a hostel for 'unmanageable' child evacuees from Edinburgh and Glasgow, active during the Second World War; the Reynolds House, a residential home for boys leaving approved schools who had no home to return to, started in London in 1963; and the Cotswold Community, a residential school for 'maladjusted' children in Wiltshire, transformed into a therapeutic community in 1967. Apart from the modifications of psychoanalytic methods made necessary by this environment, a key question posed by these communities is what constitutes healing social relationships at large, and how psychoanalysis can be instrumental in building and maintaining them.

The escalating global concerns surrounding radicalization and violent extremism necessitate a comprehensive understanding and explanation. Identifying the risk factors associated with radicalism and violent extremism is critical to the development of risk assessment, prevention, and intervention strategies. It is imperative to distinguish these risks from civic responsibilities (i.e., activism) to safeguard individual rights. This study aims to examine the association between well-established risk factors for violence—personality disorder symptoms—and violent extremist attitudes, radicalism, and activism. Findings indicate that antisocial personality disorder symptoms were linked to violent extremist attitudes and radicalism, whereas obsessive-compulsive disorder symptoms were related to activism. This suggests that obsessive-compulsive personality disorder may signify a readiness for legal and nonviolent political action; in contrast, antisocial personality disorder symptoms signify a readiness for extremist violence and illegal political action.

Adolescents with antisocial traits are more likely to commit violence and experience negative outcomes later in life. There is evidence for gender differences in the manifestations of antisocial personality features and functions of aggression, but little research has sought to assess unique gender differences that may help unravel the sequelae of antisocial traits in youth. Accordingly, this study examines gender differences in associations between the Personality Assessment Inventory Adolescent (PAI-A) Antisocial scale and its subscales – Egocentricity, Antisocial Behaviors, and Stimulus-Seeking -- and forms and functions of aggression in a sample of at-risk youth. Four hundred and sixty-four adolescents (Mage = 16.75 years, 84.9% boys) participating in a military-style bootcamp for at-risk 16- to 18- year-olds self-reported information about personality and aggression. Results revealed boys reported more antisocial features and overt, but not relational, aggression than girls. Antisocial features were linked to all aggression constructs across gender, with stronger links emerging between antisocial features and relational aggression among girls compared to boys. Gender differences also emerged in associations between specific antisocial features and aggression; egocentricity was uniquely linked to all aggression constructs only among girls, and some evidence suggests a unique link between sensation seeking and overt aggression among boys. These findings indicate specific antisocial features may be differentially linked to aggression in at-risk girls and boys, supporting a growing body of literature suggesting gender specific pathways to aggression which may be useful for identifying opportunities to disrupt negative outcomes in these youth.

This study investigates the complex relationships between parental attitudes, teacher attitudes, and self-control and their associations with prosocial and antisocial behaviour among adolescents in Bali, Indonesia. The research utilises a correlational research design with structural equation modelling (SEM) analysis to examine the relationships among variables comprehensively. A sample of 260 high school students aged 14 to 16 in Bali, Indonesia, was selected using a multi-stage cluster random sampling technique with 104 male and 156 female. The standard deviation of age is 0.49. Data were collected using adapted instruments to measure prosocial behaviour, antisocial behaviour, parents' attitudes, teachers' attitudes, and self-control. The study found positive correlations between parental attitudes, teacher attitudes, self-control, and prosocial behaviour and negative correlations with antisocial behaviour. The SEM analysis produced a predictive model for adolescent prosocial and antisocial behaviour, demonstrating strong compatibility with the model. The results indicated that parents' attitudes, teachers' attitudes, and self-control contributed significantly to prosocial behaviour among adolescents. However, while teachers' attitudes and self-control were significantly related to antisocial behaviour, no significant relationship was found between parents' attitudes and antisocial behaviour. The findings provide valuable insights into the role of parent-child relationships and highlight the potential for fostering positive behavioural outcomes. The study's contribution lies in its focus on multiple dimensions of relationships and its exploration of the impact of parental difficulties. Ultimately, this research deepens the understanding of prosocial and antisocial behaviour and its underlying mechanisms, shedding new light on the field of prosocial. [ABSTRACT FROM AUTHOR]

Although social influences have been identified that protect against the intergenerational transmission of antisocial behavior, there has been no prior research on biological protective factors. This study examines whether high resting heart rate may be one such factor. Resting heart rate was measured in 405 children of parents from a birth cohort, together with antisocial behavior in both the parent and the child. Children who were not antisocial, but had a parent high on antisocial behavior, had higher resting heart rates than all three other parent–child antisocial behavior groupings. Results withstood control for age, gender, ethnicity, body mass index, and psychosocial adversity. Robustness checks confirmed these results. Findings are the first to identify a biological protective factor against the intergenerational transmission of childhood antisocial behavior. [ABSTRACT FROM AUTHOR]

Background: Knowledge of the association between parental personality disorders and mental disorders in children is limited. To examine the association between parental personality disorders and the risk of mental disorders in offspring. Methods: We linked Danish health registers to create a cohort of children born from January 1, 1995, to December 31, 2016. Children were followed until their 18th birthday, diagnosis set, emigration, death, or December 31, 2016. Parental personality disorders according to the International Classification of Diseases (ICD) Eighth or 10th Revision. Poisson regression analyses were used to estimate the incidence risk ratio (IRR) and cumulative incidence of ICD 10th mental disorders in offspring (age 0–17). Results: The study cohort included 1,406,965 children. For girls, maternal or paternal personality disorder (MPD/PPD) was associated with mental disorders: MPD girls (IRR, 2.74; 95% CI, 2.59–2.89) and PPD girls (IRR, 2.10; 95% CI, 1.94–2.27). Likewise, the risk was increased for both MPD boys (IRR, 2.44; 95% CI, 2.33–2.56) and PPD boys (IRR, 2.04; 95% CI, 1.91–2.18). For girls and boys combined, exposure to two parents with a personality disorder was associated with the highest risk (IRR, 3.69; 95% CI, 3.15–4.33). At age 18, the cumulative incidence of any mental disorder in children of one or two parents with a personality disorder was 34.1% (95% CI, 33.0–35.1), which was twice the cumulative incidence of mental disorders in nonexposed children (15.2% [95% CI, 15.1–15.3]). Conclusion: Children of parents with a personality disorder were at a 2 to 3.5 times higher risk of mental disorders compared with nonexposed offspring. Possible mechanisms of transmission of mental disorders from parent to child involve genetic, environmental, and gene–environment pathways. More research into these mechanisms and research into preventive interventions is warranted. [ABSTRACT FROM AUTHOR]

Personality disorders refer to a collection of mental health conditions defined by persistent deviations from societal norms in thoughts, behaviors, and emotions. These deviations frequently result in challenges in interpersonal relationships, self-perception, and overall functioning, potentially causing distress in various aspects of life. The DSM-5 classifies personality disorders into three clusters. Cluster A contains paranoid, schizoid and schizotypal personality disorders which are characterized by strange and eccentric behaviors. Cluster B contains narcissistic, histrionic and antisocial personality disorders which are characterized by dramatic and emotional behaviors. Cluster C contains avoidant, dependent and obsessive-compulsive personality disorders which are characterized by anxious and fearful behaviors.

To date, characteristics of the internet "troll" have largely been explored in general community samples, which may lack representation of the sample of interest. In this brief report, we aimed to evidence the role of gender and the personality traits of sadism, psychopathy, extraversion, conscientiousness, and agreeableness in a sample of individuals who self-report having perpetrating trolling behaviours. Participants (N = 163; 50.3% women; Mage = 27.35, SD = 8.78) were recruited via social media advertisements and completed an anonymous online questionnaire. The variables explained 55.5% of variance in trolling. We found self-reported trolls were more likely to be men and have higher psychopathy, higher sadism, and lower agreeableness. Findings of this representative sample have implications for understanding, managing, and preventing this antisocial online behaviour. [ABSTRACT FROM AUTHOR]

The current study investigated in-the-moment links between adolescents' autonomic nervous system activity and susceptibility to three types of peer influence (indirect, direct, continuing) on two types of behavior (antisocial, prosocial). The sample included 144 racially ethnically diverse adolescents (46% male, 53% female, 1% other; M age  = 16.02 years). We assessed susceptibility to peer influence behaviorally using the Public Goods Game (PGG) while measuring adolescents' mean heart rate (MHR) and pre-ejection period (PEP). Three key findings emerged from bivariate dual latent change score modeling: (1) adolescents whose MHR increased more as they transitioned from playing the PGG alone (pre-influence) to playing while simply observed by peers (indirect influence) displayed more prosocial behavior; (2) adolescents whose PEP activity increased more (greater PEP activity = shorter PEP latency) as they transitioned from indirect influence to being encouraged by peers to engage in antisocial behavior (direct influence) engaged in more antisocial behavior; and (3) adolescents whose PEP activity decreased less as they transitioned from direct influence on prosocial behavior to playing the PGG alone again (continuing influence) displayed more continuing prosocial behavior (marginal effect). The discussion focuses on the role of psychophysiology in understanding adolescents' susceptibility to peer influence. [ABSTRACT FROM AUTHOR]

A paucity of cognitive and affective features of empathy can be correlated with violent behavior. We aimed to identify differences in empathy among four groups in a sample of 100 male participants: (1) 27 violent offenders with schizophrenia, (2) 23 nonviolent patients with schizophrenia, (3) 25 patients with antisocial personality disorder, and (4) 25 subjects from the general population, who formed the control group. Schizophrenia symptoms were quantified with the Positive and Negative Syndrome Scale. Empathy was measured with the empathy quotient. Theory of mind was evaluated using (a) the first-order false-belief task, (b) the hinting task, (c) the faux pas recognition test and (d) the "reading the mind in the eyes" test (revised). Differences noted among the groups were age (controls were younger) and educational status (antisocials were less educated). The empathy quotient scoring (p < 0.001) and theory-of-mind tests (p < 0.001) were distinct between the control group and the three other groups of participants, but not among the three patient groups. Patients with antisocial personality disorder, violent psychotic offenders and psychotic nonviolent patients show no remarkable differences in affective or cognitive empathy tests, but they all present deficits in empathy and theory of mind when compared to controls.

Introduction: Personality disorders have a wide impact on people's personal and social life. Aim: The present study aimed to determine the degree of differentiation of cluster B personality disorders based on interpersonal problems. Method: The design of the current research was descriptive and of a comparative causal type. The statistical population included all people with cluster B personality disorder in the 5 districts of Arak city in 2022. Based on the number of research groups and variables, 120 people were selected from among those who referred to the psychology and addiction treatment centers of Arak city using the available method and responded to the Clinical Multiaxial Scales of Milon version 4 (2015) and Interpersonal Problems (1996), people were also evaluated by Structured Clinical Interview for Personality Disorders (2016). To analyze the data, the discriminant analysis method was used in SPSS software version 26. Results: The results indicate a significant difference between the components of sociable (P=0.001), assertive (P=0.001), aggressive (P=0.001), caring (P=0.001), dependent (P=0.008), supportive (P=0.001), and involved (P=0.001) in the studied groups, but did not show a significant difference between the studied groups (P=0.14). In total, based on the evaluated components, 68.3% of the participants were correctly placed in their groups. Conclusion: Considering that in the present study, most of the dimensions of interpersonal problems were significant in people with cluster B personality disorders, as a result, this variable can be used to differentiate the personality disorders of this cluster and also the intervention plan.

Intimate partner violence (IPV), which can include physical and psychological harm toward an intimate partner, is a significant problem on college campuses with 20%–50% of college students reporting victimization during their college careers. The intergenerational transmission of violence theory suggests that Family of Origin Violence (FOV; e.g., witnessing IPV between parental figures and experiencing childhood physical abuse) increases the likelihood of perpetrating IPV as an adult. FOV is also associated with an increased risk of developing antisocial personality traits, a correlate of IPV perpetration. We examined whether antisocial personality traits explained the relationship between FOV (i.e., experiencing and witnessing) and four different types of emotional partner abuse (i.e., restrictive engulfment, denigration, hostile withdrawal, and dominance/intimidation) while controlling for sex, alcohol, and drug use/problems. Experiencing FOV positively associated with restrictive engulfment emotional partner abuse (B =.04, 95% CI [.01,.08]), hostile withdrawal emotional partner abuse (B =.07, 95% CI [.03,.13]), and dominance/intimidation emotional partner abuse (B =.04, 95% CI [.01,.09]) through antisocial personality traits. These findings have implications for the long-term consequences of FOV. [ABSTRACT FROM AUTHOR]

El presente estudio tuvo como objetivo el diseño y validación de una escala para evaluar comportamiento contraproducente en línea que incluye el análisis conjunto de conductas destructivas (antisociales) y constructivas (prosociales). Además, se propuso determinar qué rasgos de personalidad (normales, patológicos, negativos o positivos) predicen dicho comportamiento. Participaron 351 sujetos de población general argentina (156 hombres, 191 mujeres, 2 se identificaron como no binarios), con una edad promedio de 39.35 años (de = 13.79). Para el cumplimiento de todos los objetivos, aparte de la prueba construida, se emplearon los siguientes instrumentos: Big Five Inventory, Personality Inventory for DSM-5 Brief-Form, Positive Traits Inventory Short-Form, Dark Triad Scale, y una encuesta diseñada ad hoc para evaluar el uso de internet y redes sociales. El análisis factorial exploratorio reveló una estructura de dos factores orientados a la evaluación de los dos tipos de conductas, que explicaban el 57.5 % de la varianza total. Como resultado, se dio lugar a una escala de 18 ítems con muy buenos valores de fiabilidad —coeficiente omega— (conductas destructivas ω = 0.88; conductas constructivas ω = 0.79). Por último, se realizaron análisis de regresión jerárquica que determinaron que los rasgos de la tríada oscura son los que mejor predicen el desarrollo de conductas destructivas, en tanto que los rasgos positivos predicen las conductas constructivas.

Research from the social sciences suggests an association between higher temperatures and increases in antisocial behaviours, including aggressive, violent, or sabotaging behaviours, and represents a heat‐facilitates‐aggression perspective. More recently, studies have shown that higher temperature experiences may also be linked to increases in prosocial behaviours, such as altruistic, sharing, or cooperative behaviours, representing a warmth‐primes‐prosociality view. However, across both literatures, there have been inconsistent findings and failures to replicate key theoretical predictions, leaving the status of temperature‐behaviour links unclear. Here we review the literature and conduct meta‐analyses of available empirical studies that have either prosocial (e.g., monetary reward, gift giving, helping behaviour) or antisocial (self‐rewarding, retaliation, sabotaging behaviour) behavioural outcome variables, with temperature as an independent variable. In an omnibus multivariate analysis (total N = 4577) with 80 effect sizes, we found that there was no reliable effect of temperature on the behavioural outcome measured. Further, we find little support for either the warmth‐primes‐prosociality view or the heat‐facilitates‐aggression view. There were no reliable effects if we consider separately the type of behavioural outcome (prosocial or antisocial), different types of temperature experience (haptic or ambient), or potential interactions with the experimental social context (positive, neutral, or negative). We discuss how these findings affect the status of existing theoretical perspectives and provide specific suggestions advancing research in this area. [ABSTRACT FROM AUTHOR]

Although prior research has established the influence of parents and peers on adolescents' bullying behaviors, there is a void in the literature of the potential mediating effect of negative peer influence in the relationship between parenting practices and bullying behaviors among a United States sample. Using data from the Pathways to Desistance study, the present study examines the mediating role of peer antisocial behavior in the association between parenting (i.e., parental monitoring and maternal warmth) and adolescents' bullying behaviors (i.e., bully perpetration, bully victimization, bully-victim, and non-involved). Results indicate that the effect of parental monitoring on youth who engaged in bully perpetration (vs. non-involved) was mediated by peer antisocial behavior. That is, poor parental monitoring increased delinquent peer association, which in turn predicted a high risk of engaging in bully perpetration. However, peer antisocial behavior did not mediate the relationship between parental monitoring and bully victimization (vs. non-involved) nor bully-victim (vs. non-involved). The findings have important implications for adolescents' bullying behavior and possible intervention programs by informing researchers and practitioners about the mechanisms surrounding multiple types of bullying behaviors.

Aggressogenic parenting styles are associated with increased rates of callous and unemotional traits, and in turn, with antisocial behaviours. Traumatic brain injury is also associated with antisocial behaviour, but not callous and unemotional traits specifically. No study has previously investigated these three variables, aggressogenic parenting, traumatic brain injury, and callous and unemotional traits, in a single study. The study setting was Cape Town, South Africa. The sample included high school boys (N = 54), aged 13–21 years in an observational, descriptive study. We hypothesised that boys who reported that they had sustained a traumatic brain injury and who had been exposed to aggressogenic parenting would display increased levels of callous and unemotional traits, and that those with traumatic brain injury but had experienced positive parenting would display lower levels of such traits. The main measures included the Comprehensive Health Assessment Tool, the Inventory of Callous/Unemotional traits, and the Alabama Parenting Questionnaire. Results show that almost 41% (22/54) of participants reported sustaining a traumatic brain injury. Aggressogenic parenting significantly moderated callous and unemotional traits only in participants with traumatic brain injury, F(1.46) = 4.76, p = .03, while positive parenting and substance use did not. In conclusion, traumatic brain injury in the presence of aggressogenic parenting is associated with greater callous and unemotional traits in this sample of adolescent boys. [ABSTRACT FROM AUTHOR]

This is the first study to test the psychometric properties of the self-report version of the Proposed Specifiers for Conduct Disorder (PSCD) in detained youth. The PSCD is a measure of the broad psychopathy construct, with grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder (CD) components. Participants (227 males) completed the PSCD along with other measures, including a diagnostic interview to assess Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM- 5) CD. Results support the PSCD's proposed hierarchical four-factor structure. Correlations with an alternate measure of psychopathy and symptoms of CD support the convergent validity of PSCD scores. PSCD scores showed positive associations with criterion variables of emotional and regulatory functioning, aggression, substance use, and school problems. Finally, PSCD scores were unrelated to anxiety and depression, supporting the PSCD's discriminant validity. Findings indicate that the PSCD is a promising measure for assessing psychopathic traits in detained male adolescents, though its incremental validity is in need of further scrutiny.

Purpose Early-life stress can cause brain inflammation and affect social behavior in adulthood. In humans, maltreated (abused or neglected) children often exhibit antisocial behavior, including violent and sadistic behavior, in adulthood. However, it is unknown whether maltreatment behavior occurs in rodents. Here, we developed an assay system to evaluate conspecific maltreatment behavior in the mouse. Methods To assess maltreatment behavior, we devised a two-chamber apparatus separated by a transparent partition, in which one chamber was provided with a nose-poking hole that would trigger foot shocks onto the other. Lidocaine was used to inhibit neural activity in vivo. Brain oscillations were investigated by electroencephalograph. Enzyme-linked immunosorbent assay was used for protein assay. The mouse model was sequentially subjected to maternal separation (MS), social defeat (SD), and social isolation (SI) in that order (MS/SD/SI model). Results Inactivation of the anterior cingulate cortex and medial prefrontal cortex increased the level of nose-poking. Maltreatment behavior provoked changes in oxytocin, corticosterone, and brain-derived neurotrophic factor levels. MS/SD/SI mice exhibited more sustained nose-poking behavior during the experiment, resulting in increased foot shocks to the mouse in the opposite chamber. Abnormal brain oscillations were observed in the MS/SD/SI mice. Conclusion The MS/SD/SI model and maltreatment-behavior assay may be useful not only to study the relationship between social stress in childhood and antisocial behavior in adulthood, but also for study of etiology, pathology, or treatment for brain disorders, such as psychopathy.

Previous work in incarcerated boys and adult men and women suggest that individuals scoring high on psychopathic traits show altered resting-state limbic/paralimbic, and default mode functional network properties. However, it is unclear whether similar results extend to high-risk adolescent girls with elevated psychopathic traits. This study examined whether psychopathic traits [assessed via the Hare Psychopathy Checklist: Youth Version (PCL:YV)] were associated with altered inter-network connectivity, intra-network connectivity (i.e., functional coherence within a network), and amplitude of low-frequency fluctuations (ALFFs) across resting-state networks among high-risk incarcerated adolescent girls (n = 40). Resting-state networks were identified by applying group independent component analysis (ICA) to resting-state fMRI scans, and a priori regions of interest included limbic, paralimbic, and default mode network components. We tested the association of psychopathic traits (PCL:YV Factor 1 measuring affective/interpersonal traits and PCL:YV Factor 2 assessing antisocial/lifestyle traits) to these three resting-state measures. PCL:YV Factor 1 scores were associated with increased low-frequency and decreased high-frequency fluctuations in components corresponding to the default mode network, as well as increased intra-network FNC in components corresponding to cognitive control networks. PCL:YV Factor 2 scores were associated with increased low-frequency fluctuations in sensorimotor networks and decreased high-frequency fluctuations in default mode, sensorimotor, and visual networks. Consistent with previous analyses in incarcerated adult women, our results suggest that psychopathic traits among incarcerated adolescent girls are associated with altered intra-network ALFFs—primarily that of increased low-frequency and decreased high-frequency fluctuations—and connectivity across multiple networks including paralimbic regions. These results suggest stable neurobiological correlates of psychopathic traits among women across development.

How do fundamental concepts from economics, such as individuals' preferences and beliefs, relate to equally fundamental concepts from psychology, such as relatively stable personality traits? Can personality traits help us better understand economic behavior across strategic contexts? We identify an antisocial personality profile and examine the role of strategic context (the "situation"), personality traits (the "person"), and their interaction on beliefs and behaviors in trust games. Antisocial individuals exhibit a specific combination of beliefs and preferences that is difficult to reconcile with a rational choice approach that assumes that beliefs about others' behaviors are formed rationally and therefore, independently from preferences. Variations in antisocial personality are associated with effect sizes that are as large as strong variations in strategic context. Antisocial individuals have lower trust in others unless they know that they can punish them. They are also substantially less trustworthy, believe that others are like themselves, and respond to the possibility of being sanctioned more strongly, suggesting that they anticipate severe punishment if they betray their partner's trust. Antisocial individuals are not simply acting in their economic self-interest, because they harshly punish those who do not reciprocate their trust, although that reduces their economic payoff, and they do so nonimpulsively and in a very calculated manner. Antisocial individuals honor others' trust significantly less (if they cannot be punished) but also, harshly punish those who betray their trust. Overall, it seems that antisocial individuals have beliefs and behaviors based on a view of the world that assumes that most others are as antisocial as they themselves are.

This cross-sectional survey conducted in southwestern Nigeria examined the common antisocial activities among adolescents and students in developing countries, using a structured questionnaire among 300 people preparing to get married. The study was conducted from September to October 2019 with an aim to the perception of people intending to marry on eradicating students and adolescents’ antisocial behavior in developing countries. Data were analyzed with IBM-SPSS version-25. Promiscuity (41.7%) topped the list of antisocial activities mentioned, followed by indecent dressing and social nuisance (27.0%). Improper parental guidance ranked highest (41.3%) as the perceived cause of antisocial and high-risk behaviors, followed by peer pressure (29.3%). Around 48% of the respondents said the parents were to blame and 26.0% said adolescents, and 15.0% said the government was to blame. Antisocial behaviors can be reduced among students and adolescents by including parenting and moral training in the education curriculum. Also, there is a need to educate parents on the essential parenting tips and methods.

Abstract Background Antisocial Personality Disorder (ASPD) describes individuals who engage in repetitive aggressiveness, deceitfulness, impulsivity, and unlawful behavior. It has a broad impact on families, relationships, and social functioning, and also people with ASPD make heavy demands on the judicial system, social and mental health services. Even though ASPD is a common problem among incarcerated in prisons, it is not well studied in developing countries including Ethiopia. Therefore, this study aimed to determine the prevalence and associated factors of ASPD among incarcerated in prison in Dessie city correctional center. Method A cross-sectional study design was conducted among 320 incarcerated in prison at Dessie correctional center, Ethiopia. The study subjects were selected by using a simple random sampling technique and the Diagnostic and Statistical Manual 5th text revision (DSM-5) was used to measure ASPD using face-to-face interviews. Social support was assessed using the Oslo social support scale (Oslo-3). The collected data were checked for completeness and entered into Epi-data Version 3.1 and then exported to SPSS version 26 for analysis. Bivariate and multivariable logistic regressions were done to identify factors related to antisocial personality disorder. In multivariable logistic regression variables with a p-value, less than 0.05 were considered significant and, adjusted OR (AOR) with 95% CI was used to present the strength of the association. Results The current study showed that the prevalence of ASPD was found to be 30.6% (95% CI:25.6,35.9). In a multivariable analysis, being single [AOR = 2.33; 95%CI (1.39,3.89)], monthly income of 1000–2000 ETB (Ethiopian Birr) [AOR = 2.12; 95%CI (1.163,3.45)], reconviction [AOR = 2.37; 95%CI (1.08,5.19)], and alcohol use [AOR = 2.00; 95% CI (1.16,3.45)] were discovered to be predictors of antisocial personality disorder. Conclusion This study revealed that nearly one-third of incarcerated in prison were found to have an anti-social personality disorder. Being single, 1000–2000 ETB income, reconviction, and alcohol users were variables that are independent predictors of ASPD. A screening and intervention program is required and further research should be needed.

Abstract Background Anorexia Nervosa is highly comorbid with depressive, anxiety, and obsessive-compulsive spectrum disorders. However, it has not previously been reported as comorbid with antisocial personality traits, except when substance use disorder is also identified. We present an unusual case of a patient with resistant anorexia nervosa and comorbid conduct disorder. This case was also unique in that the juvenile justice system was involved during treatment. Case presentation A 13-year-old female was admitted to our pediatric hospital for the treatment of anorexia nervosa. She had a history of violent behaviors toward family members, often jeopardizing her care. During hospitalization, she physically attacked a physician on her care team shortly before she transitioned to an eating disorders treatment program. She was diagnosed with conduct disorder, and following discharge, she attacked her father in a premeditated act. This led to her entry into the juvenile justice system. While under the custody of the juvenile justice system, she was readmitted to our hospital for further treatment of anorexia nervosa. Our treatment strategy included psychotropics, positive reinforcement, close interdisciplinary coordination among the various hospital teams, and the juvenile justice system. Following discharge from her second hospitalization back to the juvenile detention system, our patient maintained a healthy weight and appeared to show improvements in the cognitive distortions related to her eating disorder. Conclusions To our knowledge, this is the first reported successful treatment of an individual with resistant anorexia nervosa and conduct disorder. It was likely a combination of weight gain, psychotropic medications, and the structured milieu provided by the juvenile justice system that led to the effective treatment of our patient. This case illustrates that a non-traditional healthcare setting can be an asset to treatment through persistence and close collaboration across institutions.

Current research supports that both psychological/physical maltreatment by parents and parent-child relationship quality strongly correlate with children's psychopathology. Less research has examined the interaction effects among these variables, especially in emerging adults. The current study analyzed the association between psychological/physical maltreatment experienced from one parent and antisocial behaviors displayed by emerging adults, as well as the moderating effect of the other parent's parent-child relationship quality. This sample included 1,364 emerging adults (953 females, 411 males) who reported on past year psychological and physical maltreatment and parent-child relationship quality. Results indicated that, when considered together, parent-child relationship quality was a stronger predictor of emerging antisocial problems than maltreatment, with the exception of the father-son dyad. Additionally, overall findings suggested that having a high-quality relationship with one caregiver was associated with lower antisocial problems in the context of high maltreatment from the other caregiver. Nevertheless, there were deviations from this norm. Unexpectedly, the lowest antisocial problems in females were associated with higher levels of paternal physical maltreatment combined with higher levels of maternal parent-child relationship quality. Moreover, the combination of low paternal psychological maltreatment and low maternal relationship quality was associated with particularly high antisocial problems in males. It is important to note the findings in the context of this sample of college students, who could be considered an advantaged group relative to some others. Since our sample might not represent our entire population of interest, which is emerging adults, it is important for future studies to examine these relationships across more diverse emerging adults. Practical implications are discussed. [ABSTRACT FROM AUTHOR]

Human needs consist of five levels, which are: physiological needs, safety needs, love needs, esteem needs and self-actualization. All these needs lead to human behavior. If the environment of a person is positive, healthy behavior is developed. However, if the environment of the person is not healthy, it can be reflected in his/her behavior. Machines are intelligent enough to mimic human intelligence by using machine learning and artificial intelligence techniques. In the modern era, people tend to post their everyday life events on social media in the form of comments, pictures, videos, etc. Therefore, social media is a significant way of knowing certain behaviors of people such as abusive, aggressive, frustrated and offensive behaviors. Behavior detection by crawling the social media profile of a person is a crucial and important idea. The challenge of behavior detection can be sorted out by applying social media forensics on social media profiles, which involves NLP and deep learning techniques. This paper is based on the study of state of the art work on behavior detection, and based on the research, a model is proposed for behavior detection. The proposed model outperformed with an F1 score of 87% in the unigram + bigram class, and in the bigram + trigram class, it gave an F1 score of 88% when compared with models applied on state of the art work. This study is a great benefit to cybercrime and cyber-security agencies in shortlisting the profiles containing certain behaviors to prevent crimes in the future. [ABSTRACT FROM AUTHOR]

Youth violence is one of the many problems facing the globe. The issue of youth violence has been declared as intolerable and catastrophic. The United Nations and the World Health organization have both agreed that effective planning and measures must be taken to guide and provide the youth a reasonable platform for a sustainable growth and development to take place. This study examined trending patterns of youth violence and criminal behaviour in Cross River State, Nigeria. The paper adopted the Robert Agnew (1991) Strain and the Gary Becker (1976) Rational Choice theory as its undercurrent in explaining the problem under study. The theories suggest that youth violence and crime is highly related to strain resulting from unequal opportunities, as well as reinforcement and perceived rewards. The method of data collection were the quantitative (questionnaire) and qualitative (key informant interview). Eight hundred (800) Likert scale well- structured questionnaires were administered and retrieved while twelve (12) Key informant interviews were administered on participants. The quantitative instruments were analyzed with the aid of SPSS version 24 in simple percentages of column and rows while the KII were analyzed using manual content analysis and ethnographic summaries. The findings revealed that youth violence is inhuman, unprogressive, criminal and deadly. The study recommends an allembracing-all-hand on deck approach, good government policies that will create employment, stabilize economy and enhance development as well as proper socialization and sensitization to correct and reduce the menace in Cross River State and beyond.

There exist extensive animal research and lesion studies in humans demonstrating a tight association between the hypothalamus and socioemotional behavior. However, human neuroimaging literature in this direction is still rather limited. In order to reexamine the functional role of this region in regulating human social behavior, we here provided a synthesis of neuroimaging studies showing hypothalamic activation during affiliative, cooperative interactions, and in relation to ticklish laughter and humor. In addition, studies reporting involvement of the hypothalamus during aggressive and antisocial interactions were also considered. Our systematic review revealed a growing number of investigations demonstrating that the evolutionary conserved hypothalamic neural circuity is involved in multiple and diverse aspects of human socioemotional behavior. On the basis of the observed heterogeneity of hypothalamus-mediated socioemotional responses, we concluded that the hypothalamus might play an extended functional role for species survival and preservation, ranging from exploratory and approaching behaviors promoting social interactions to aggressive and avoidance responses protecting and defending the established social bonds.
