Anxiety disorders among offenders with antisocial personality disorders: a distinct subtype?

Antisocial personality disorder and associated factors among incarcerated in prison in Dessie city correctional center, Dessie, Ethiopia: a cross-sectional study

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.

Prevalence and correlates of antisocial personality disorder in older adults

OBJECTIVES

There is a paucity of research on antisocial personality disorder (ASPD) in the geriatric population and the majority of knowledge on the disorder is drawn from young adult samples. Researchers posit that the prevalence of ASPD as well as other personality disorders (PDs) is underestimated among older adults. Using a nationally representative sample, the present study examines the prevalence and correlates of ASPD in adults ages 50 and older.

METHODS

We analyzed data from the National Epidemiologic Survey on Alcohol and Related Conditions Waves I and III. Multivariate logistic regression analyses were employed to investigate associations between ASPD and sociodemographic characteristics. A series of logistic regression analyses were also conducted to study associations between ASPD and medical conditions (liver and cardiovascular disease, arthritis, and stomach ulcer), major psychiatric disorders (lifetime major depressive disorder, mania, and generalized anxiety disorder), and substance use disorders (lifetime alcohol, marijuana, cocaine, heroin, and nicotine use disorders).

RESULTS

Findings indicated that the prevalence of ASPD increases through early adulthood, with a peak at 3.91% in younger adults and decline to 0.78% in adults ages ≥65. Older adults with ASPD are more likely to be diagnosed with a substance use disorder, major depression, mania, and generalized anxiety disorder as well as each medical condition.

CONCLUSION

Older adults with ASPD experience increased rates of medical and psychiatric comorbidities. These conditions exacerbate the existing challenges associated with diagnosing and treating this population and may have serious consequences for the patient, their caregivers and society.

How do childhood conduct problems, callousness and anxiety relate to later offending and adult mental disorder?

BACKGROUND

Various combinations of childhood conduct problems, callous traits and anxiety may confer increased risk of offending, psychopathic traits and mental disorders. Knowledge of these outcomes in adulthood is limited.

AIMS

To compare adult criminal convictions, psychopathy checklist scores and mental disorders between five groups of men, variously defined in childhood by: (1) callous traits, (2) conduct problems, (3) conduct problems and callous traits, (4) conduct problems and callous traits and anxiety or (5) developing typically.

METHOD

Teachers rated conduct problems, callous traits and anxiety at ages 6, 10 and 12 years. Criminal convictions from age 12 to 24 were extracted from official records. The Psychopathy Checklist-Revised (PCL-R) and diagnostic interviews were completed at age 33.

RESULTS

Relative to the typically developing group, the groups with conduct problems, with and without callous traits and anxiety, showed 5-fold elevations in risks of violent convictions and 3 to 4-fold elevations in risk for antisocial personality disorder, while the groups with conduct problems only and with conduct problems plus callous traits plus anxiety were at increased risk for borderline personality disorder. All risk groups obtained higher PCL-R total scores than the typically developing childhood group.

CONCLUSIONS AND IMPLICATIONS

It is widely accepted that childhood conduct problems in boys are associated with increased risks of criminal convictions and poorer mental health, but our findings suggest that teachers can identify different subgroups and these have different trajectories. As some subgroups were small, replication is recommended, but our findings offer preliminary support for trialling specific interventions for at risk boys.

Developmental joint trajectories of anxiety-depressive trait and trait-aggression: implications for co-occurrence of internalizing and externalizing problems

BACKGROUND

In youth, anxiety-depressive traits (ADT) and trait-aggression (TA) are important risk factors of exhibiting maladaptive behaviors in adulthood (i.e. violence and substance use). However, the developmental co-occurrence of these traits in youth remains unknown. We thus sought to investigate the developmental trajectories of ADT and TA within a data-driven approach. The aim was two-fold: (i) to examine the developmental trajectories of ADT and TA in youth from ages 10 to 16, and (ii) to investigate both childhood predictors and problematic outcomes of the identified joint trajectories.

METHOD

The sample comprised 1354 children provided from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) Consortium. Group-based trajectory modeling was first employed to identify individual trajectory models of ADT and TA independently (from ages 10 to 16). Then, joint trajectory models were built on the found trajectories. Last, logistic regressions were used to evaluate the childhood characteristics and negative outcomes of the joint trajectory groups.

RESULTS

Our results showed five trajectory groups with varying levels of ADT and TA. A significant co-occurrence between ADT and TA was found in three of the trajectory groups. Notably, higher levels of childhood psychopathology and more severe/frequent childhood abuse were found in the groups with moderate to high ADT and high TA. The groups with higher ADT and high TA were also more likely to exhibit violence and substance use.

CONCLUSIONS

This study exposes the importance of assessing ADT and TA simultaneously and early in childhood to prevent and manage the risk of problematic behaviors in adolescence.

Offending behaviour, health and wellbeing of military veterans in the criminal justice system

BACKGROUND

A small but significant proportion of military veterans become involved in the criminal justice system (CJS) after leaving service. Liaison and Diversion (L&D) services aim to identify vulnerable offenders in order to provide them with the health/welfare support they need, and (where possible) divert them away from custody. An administrative database of L&D service-users was utilised to compare the needs of veterans with those of non-veteran L&D service-users.

METHOD

National data collected from 29 L&D services in 2015-2016 was utilised. Of the 62,397 cases, 1,067 (2%) reported previous service in the Armed Forces, and 48,578 had no previous service history. The associations between veteran status and socio-demographic characteristics, offending behaviour, health- and mental health-problems were explored. The associations between specific types of offending and mental health problems within the veterans in the sample were also investigated.

RESULTS

Veterans tended to be older, and less likely to be unemployed than non-veterans, but just as likely to have unstable living arrangements (including homelessness). Veteran status was associated with increased levels of interpersonal violence, motoring offences, anxiety disorders and hazardous drinking patterns. Veteran status was associated with decreased levels of acquisitive offending, schizophrenia, ADHD, and substance misuse. Among veterans, the presence of an anxiety disorder (umbrella term which included GAD, Phobias, PTSD etc.) was associated with increased interpersonal violence, alcohol misuse was associated with increased motoring offences, and substance use was associated with increased acquisitive offending.

CONCLUSIONS

Our study indicates that among offenders in the CJS who have been identified as needing health or welfare support, veterans differ from non-veterans in terms of their health and welfare needs and offending behaviour. These differences may be influenced by the impact of military service and the transition into civilian life. Our findings support the identification of military personnel within the CJS to provide appropriate interventions and support to improve outcomes and reduce offending.

Associations of monoamine oxidase A gene first exon methylation with sexual abuse and current depression in women

Childhood physical abuse (PA) and sexual abuse (SA) interact with monoamine oxidase A (MAOA) gene polymorphism to modify risk for mental disorders. In addition, PA and SA may alter gene activity through epigenetic mechanisms such as DNA methylation, thereby further modifying risk for disorders. We investigated whether methylation in a region spanning the MAOA first exon and part of the first intron was associated with PA and/or SA, MAOA genotype, alcohol dependence, drug dependence, depression disorders, anxiety disorders, and conduct disorder. 114 Swedish women completed standardized diagnostic interviews and questionnaires to report PA and SA, and provided saliva samples for DNA extraction. DNA was genotyped for MAOA-uVNTR polymorphisms, and methylation of a MAOA region of interest (chrX: 43,515,544–43,515,991) was measured. SA, not PA, was associated with hypermethylation of the MAOA first exon relative to no-abuse, and the association was robust to adjustment for psychoactive medication, alcohol and drug dependence, and current substance use. SA and MAOA-uVNTR genotype, but not their interaction, was associated with MAOA methylation. SA associated with all measured mental disorders. Hypermethylation of MAOA first exon mediated the association of SA with current depression, and both methylation levels and SA independently predicted lifetime depression. Much remains to be learned about the independent effects of SA and MAOA-uVNTR genotypes on methylation of the MAOA first exon.

Amygdala-orbitofrontal structural and functional connectivity in females with anxiety disorders, with and without a history of conduct disorder

Conduct disorder (CD) and anxiety disorders (ADs) are often comorbid and both are characterized by hyper-sensitivity to threat, and reduced structural and functional connectivity between the amygdala and orbitofrontal cortex (OFC). Previous studies of CD have not taken account of ADs nor directly compared connectivity in the two disorders. We examined three groups of young women: 23 presenting CD and lifetime AD; 30 presenting lifetime AD and not CD; and 17 with neither disorder (ND). Participants completed clinical assessments and diffusion-weighted and resting-state functional MRI scans. The uncinate fasciculus was reconstructed using tractography and manual dissection, and structural measures extracted. Correlations of resting-state activity between amygdala and OFC seeds were computed. The CD + AD and AD groups showed similarly reduced structural integrity of the left uncinate compared to ND, even after adjusting for IQ, psychiatric comorbidity, and childhood maltreatment. Uncinate integrity was associated with harm avoidance traits among AD-only women, and with the interaction of poor anger control and anxiety symptoms among CD + AD women. Groups did not differ in functional connectivity. Reduced uncinate integrity observed in CD + AD and AD-only women may reflect deficient emotion regulation in response to threat, common to both disorders, while other neural mechanisms determine the behavioral response.

Trait Anger, Physical Aggression, and Violent Offending in Antisocial and Borderline Personality Disorders

Antisocial personality disorder (ASPD) and borderline personality disorder (BPD) are common conditions in forensic settings that present high rates of violence. Personality traits related to the five-factor model personality domains of neuroticism and agreeableness have shown a relationship with physical aggression in nonclinical and general psychiatric samples. The aim of the present investigation was to examine the association of these personality traits with violence and aggression in ASPD and BPD. Results revealed that trait anger/hostility predicted self-reported physical aggression in 47 ASPD and BPD subjects (β = 0.5, p = 0.03) and number of violent convictions in a subsample of the ASPD participants (β = 0.2, p = 0.009). These preliminary results suggest that high anger and hostility are associated with physical aggression in BPD and ASPD. Application of validated, self-report personality measures could provide useful and easily accessible information to supplement clinical risk assessment of violence in these conditions.

Paranoid Ideation and Violence: Meta-analysis of Individual Subject Data of 7 Population Surveys

There is controversy whether associations between psychosis and violence are due to coexisting substance misuse and factors increasing risk in nonpsychotic persons. Recent studies in clinical samples have implicated independent effects of paranoid delusions. Research findings suggest that individual psychotic-like-experiences on the psychosis continuum in the general population are associated with violence; it remains unclear whether this association is due to psychiatric comorbidity. We pooled data from 7 UK general population surveys (n = 23 444) and conducted a meta-analysis of individual subject data. Further meta-analyses were performed to identify heterogeneity. Main exposure variables: 5 psychotic-like-experiences and a categorical measure of psychosis. Comorbidity was established through standardized self-report instruments. Information was collected on violence, severity, victims. Paranoid ideation was associated with violence (AOR 2.26, 95% CI 1.75-2.91), severity and frequency, even when controlling for effects of other psychotic-like-experiences. Associations were not explained by comorbid conditions, including substance dependence. Psychotic disorder was associated with violence and injury to the perpetrator but associations were explained by paranoid ideation. Individual associations between hypomania, thought insertion, hallucinations, and violence were nonsignificant after adjustments, and significantly associated only when comorbid with antisocial personality disorder. Strange experiences were only associated with intimate partner violence. Paranoid ideation on a psychosis-continuum in the general population was associated with violence. All other associations were explained by comorbidity. Further investigation should determine whether paranoid ideation among persons in the community require preventive interventions, similar to those presenting to mental health services. Nevertheless, risks are considerably increased for psychotic-like-experiences with co-occurring antisocial personality disorder.

Possible role of a dysregulation of the endogenous opioid system in antisocial personality disorder

Around half the inmates in prison institutions have antisocial personality disorder (ASPD). A recent theory has proposed that a dysfunction of the endogenous opioid system (EOS) underlies the neurobiology of borderline personality disorder (BPD). In the present theoretical paper, based on a comprehensive database and hand search of the relevant literature, this hypothesis is extended to ASPD, which may be the predominant expression of EOS dysfunction in men, while the same pathology underlies BPD in women. According to evidence from human and animal studies, the problematic behaviours of persons with antisocial, callous, or psychopathic traits may be seen as desperate, unconscious attempts to stimulate their deficient EOS, which plays a key role in brain reward circuits. If the needs of this system are not being met, the affected persons experience dysphoric mood, discomfort, or irritability, and strive to increase binding of endogenous opioids to receptors by using the rewarding effects of aggression by exertion of physical or manipulative power on others, by abusing alcohol or substances that have the reward system as target, by creating an "endorphin rush" by self-harm, by increasing the frequency of their sexual contacts, or by impulsive actions and sensation seeking. Symptoms associated with ASPD can be treated with opioid antagonists like naltrexone, naloxone, or nalmefene.

The association between childhood maltreatment, mental health problems, and aggression in justice-involved boys

The link between childhood maltreatment and adolescent aggression is well documented; yet, studies examining potential mechanisms that explain this association are limited. In the present study, we tested the association between childhood maltreatment and adolescent aggression in boys in juvenile justice facilities (N = 767) and examined the contribution of mental health problems to this relationship. Data on childhood maltreatment, mental health problems, and aggression were collected by means of self-report measures and structural equation models were used to test mediation models. We found that mental health problems mediated the link between maltreatment and aggression. Results demonstrated different pathways depending on the type of aggression examined. The association between childhood maltreatment and reactive aggression was fully mediated by a variety of mental health problems and for proactive aggression the association was partially mediated by mental health problems. We also found that reactive and proactive aggression partially mediated the association between maltreatment and mental health problems. These findings suggest that a transactional model may best explain the negative effects of childhood trauma on mental health problems and (in particular reactive) aggression. In addition, our findings add to the existing evidence that reactive and proactive aggression have different etiological pathways.

Do psychopathic traits assessed in mid-adolescence predict mental health, psychosocial, and antisocial, including criminal outcomes, over the subsequent 5 years?

OBJECTIVE

To determine whether psychopathic traits assessed in mid-adolescence predicted mental health, psychosocial, and antisocial (including criminal) outcomes 5 years later and would thereby provide advantages over diagnosing conduct disorder (CD).

METHOD

Eighty-six women and 61 men were assessed in mid-adolescence when they first contacted a clinic for substance misuse and were reassessed 5 years later. Assessments in adolescence include the Psychopathy Checklist-Youth Version (PCL-YV), and depending on their age, either the Kiddie-Schedule for Affective Disorders and Schizophrenia for School-Aged Children or the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID). Assessments in early adulthood included the SCID, self-reports of psychosocial functioning, aggressive behaviour, and criminality and official criminal records.

RESULTS

The antisocial facet score positively predicted the number of anxiety symptoms and likelihood of receiving treatment for substance use disorders (SUDs). Lifestyle and antisocial facet scores negatively predicted Global Assessment of Functioning scores. By contrast, the interpersonal score and male sex independently and positively predicted the number of months worked or studied, as did the interaction of Lifestyle × Sex indicating that among men, but not women, an increase in lifestyle facet score was associated with less time worked or studied. Interpersonal and antisocial scores positively predicted school drop-out. Antisocial facet scores predicted the number of symptoms of antisocial personality disorder, alcohol and SUDs, and violent and nonviolent criminality but much more strongly among males than females. Predictions from numbers of CD symptoms were similar.

CONCLUSIONS

Psychopathic traits among adolescents who misuse substances predict an array of outcomes over the subsequent 5 years. Information on the levels of these traits may be useful for planning treatment.

Antisocial personality disorder: a current review

The Diagnostic and Statistical Manual of Mental Disorders (DSM 5) classification of antisocial personality disorder (ASPD) describes individuals who engage in repetitive irresponsible, delinquent, and criminal behavior. The diagnosis is highly controversial, with many researchers and clinicians arguing that the category is too heterogeneous, overinclusive, and demonstrates considerable overlap with other disorders. This review focuses on recent studies that have improved our understanding of the characteristics of individuals who fit the ASPD definition by exploring how subtypes differ and how comorbid conditions influence the presentation of ASPD. In addition, we discuss research on the etiology of ASPD that has identified genetic and environmental factors that may contribute to the development and persistence of antisocial behavior, and brain imaging research that has improved our understanding of the relationships between ASPD and other psychopathology. Finally, we discuss promising preliminary research on treatment for this disorder.

Teachers' ratings of childhood behaviours predict adolescent and adult crime among 3016 males and females

OBJECTIVE

To examine associations of teacher-rated conduct problems (CP) and hurtful and uncaring behaviours (HUB) at age 6 and 10 with criminal convictions up to age 24 among 1593 males and 1423 females, and to determine whether aggressive behaviour at age 12 mediated the associations of CP and HUB with criminal convictions.

METHOD

Teachers assessed HUB and CP at ages 6 and 10 and ratings above the 90th percentile at each age and within each sex were used to assign participants to 1 of 4 groups. Teachers assessed proactive, reactive, indirect, and verbal aggression at age 12. Juvenile and adult criminal records were obtained.

RESULTS

High CP and HUB males, aged 6, were 4 times more likely than males with lower ratings to acquire convictions for violent crimes and 5 times more likely to acquire convictions for nonviolent crimes by age 24. High HUB and CP females, aged 6, were 5 times more likely than females with lower ratings to have a conviction for a nonviolent offence by age 24. Among males, both aged 6 and 10, high HUB without CP were associated with elevations at risk of convictions for violent and nonviolent crimes, while among females the elevations at risk were limited to convictions for nonviolent crimes. Different types of aggressive behaviour mediated associations of high HUB and CP with subsequent criminal convictions, but not the association of HUB without CP and crime.

CONCLUSIONS

Teachers in elementary schools rated behaviours that, from age 6 onward, significantly predicted criminal convictions into early adulthood.

Comorbidity of conduct disorder symptoms and internalising problems in children: investigating a community and a clinical sample

Previous studies have demonstrated that many children with conduct problems (CP) also show internalising psychopathology (IP). However, it remains unclear whether the presence of IP serves as a protective or risk factor for the severity and development of CP. The aim of the present study was to assess the prevalence and associations of comorbid IP in children with CP in a community and a clinical sample. Data from boys as well as girls with CP in the clinical range were obtained from a community sample (n = 1,160) and a clinical sample diagnosed with disruptive behaviour disorder (n = 193) from two European countries. In the community sample, information was obtained using the strengths and difficulties questionnaire, whereas in the clinical sample, the child behaviour checklist was used. Internalising disorders, according to ICD-10, were also assessed in the clinical sample. For both samples, age, gender, and impact of comorbid IP in the clinical range (above 90th percentile) for CP were explored. Results revealed that in both samples, participants with CP showed a high rate of comorbid IP (community sample: 35%; clinical sample: 78%). Participants with comorbid IP were more likely to experience social problems with peers. In the clinical sample, comorbid IP rated by the parents was more prevalent than internalising disorders according to ICD-10. Boys with CP and comorbid IP demonstrated a higher severity of externalising behaviour than boys without comorbid IP in the clinical sample. We concluded that in both samples, we found a high co-occurrence of CP and IP. Based on the idea that the co-occurrence of IP and CP in children and adolescents may potentially lead to increased antisocial behaviour, internalising psychopathology should be carefully investigated. Effective strategies and specific risk factors must be evaluated to treat comorbidity as early as possible in children with CP and IP.

Associations between trait anxiety and psychopathological characteristics of children at high risk for severe antisocial development

It is thought that among children at a high risk for antisocial personality disorder, the level of individual anxiety might constitute an important marker with respect to symptomatology and prognosis. The aim of the present study was to examine whether associations between anxiety and subtypes of aggression (proactive and reactive) exist in boys with early-onset subtype of conduct disorder (CD) and co-morbid attention-deficit hyperactivity disorder (ADHD). A detailed psychometric characterization of boys with ADHD and the early-onset subtype of CD (n = 33) compared to healthy controls (n = 33) was performed. The assessment included trait anxiety, internalizing and externalizing problems, symptoms of psychopathy and temperament traits, as well as subtypes of aggressive behavior. Descriptive statistics, correlation analyses, and group comparisons were calculated. The clinical group was characterized by higher levels of externalizing and internalizing symptoms. Individual anxiety was positively associated with harm avoidance, symptoms of oppositional defiant disorder (ODD), and by trend with reactive aggression. In contrast, boys with reduced levels of anxiety exhibited more callous-unemotional traits. Our results indicate that children with the early-onset subtype of CD and ADHD constitute a psychopathological heterogeneous group. The associations between individual levels of trait anxiety, temperament traits, and subtypes of aggressive behavior in children with ADHD and severe antisocial behavior emphasize the impact of anxiety as a potential key factor that might also be crucial for improvement in therapeutic strategies and outcome measures. Anxiety should be considered carefully in children with ADHD and the early-onset subtype of CD in order to optimize current therapeutic interventions.
