Prevalence and correlates of psychopathic traits in the household population of Great Britain

There are no previous surveys of psychopathy and psychopathic traits in representative general population samples using standardized instruments. This study aimed to measure prevalence and correlates of psychopathic traits, based on a two-phase survey using the Psychopathy Checklist: Screening Version (PCL: SV) in 638 individuals, 16-74 years, in households in England, Wales and Scotland. The weighted prevalence of psychopathy was 0.6% (95% CI: 0.2-1.6) at a cut score of 13, similar to the noncriminal/nonpsychiatric sample described in the manual of the PCL: SV. Psychopathy scores correlated with: younger age, male gender; suicide attempts, violent behaviour, imprisonment and homelessness; drug dependence; histrionic, borderline and adult antisocial personality disorders; panic and obsessive-compulsive disorders. This survey demonstrated that, as measured by the PCL: SV, psychopathy is rare, affecting less than 1% of the household population, although it is prevalent among prisoners, homeless persons, and psychiatric admissions. There is a half-normal distribution of psychopathic traits in the general population, with the majority having no traits, a significant proportion with non-zero values, and a severe subgroup of persons with multiple associated social and behavioral problems. This distribution has implications for research into the etiology of psychopathy and its implications for society

The Intergenerational Transmission of Criminal Offending: Exploring Gender-specific Mechanisms

The intergenerational transmission of criminal behaviour is well-recognized, but less is known about the mechanisms that may explain it. This study presents new analyses from the Cambridge Study in Delinquent Development, which examine the intergenerational transmission of criminal convictions. It then investigates mediation via psychosocial risk factors. The convictions of fathers and mothers were significantly related to the convictions of their male offspring, and this was mediated via the fathers’ drug use. However, the convictions of fathers were only indirectly related to the convictions of female offspring via the father’s cohabitation problems. The convictions of mothers were also indirectly related to those of the female offspring through harsh parental discipline. Accurate identification of the role that psychosocial risk factors play in intergenerational pathways for males and females can inform much more effective gender-specific prevention.This work is sponsored by the Home Office, the Department of Health, the Department for Education, the Rayne Foundation, the Barrow Cadbury Trust and the Smith Richardson Foundation.This is the final version of the article.

A longitudinal analysis of the criminal careers of IPV offender subtypes : results from a prospective survey of males

Using data from the Cambridge Study in Delinquent Development, a prospective longitudinal survey of more than 400 males in the United Kingdom followed from age 8 years to age 48 years, we investigated the role of Cluster B personality traits and the association with violent offending groups based on a typology theory of male intimate partner violence (IPV) perpetrators: those who committed family-only violence and the generally violent offender. We also considered whether offending/violent groups could be predicted using risk factors measured in childhood, adolescence, and adulthood. Our findings suggest that those men who are violent both within and outside the home (the generally violent men) are distinguished from those who are involved in IPV within the home only. The differences appear to be more in degree than in kind. We discuss these findings in relation to the idea of specific interventions and policy

Measuring IPDE-SQ personality disorder prevalence in pre-sentence and early-stage prison populations, with sub-type estimates

Understanding the prevalence and type of personality disorder within prison systems allows for the effective targeting of resources to implement strategies to alleviate symptoms, manage behaviour and attempt to reduce re-offending. This study aimed to determine the prevalence of personality disorder (PD) traits within a local urban high-turnover adult male prison with a remand/recently sentenced population in London, UK. The International Personality Disorder Examination–Screening Questionnaire (IPDE-SQ) self-administered questionnaire (ICD-10 version) was completed by 283 prisoners (42% completion rate). 77% of respondents reached the threshold for one or more PDs. The most common PD types were Paranoid PD (44.5%), Anankastic PD (40.3%), Schizoid PD (35%) and Dissocial PD (25.8%). These results confirm and extend existing knowledge regarding the prevalence of PD in prison populations into a high-turnover, urban, remand population. The stark comparison with community samples indicates that a more equitable standard of service delivery within the criminal justice system, focussing on preventive and early intervention services, is now required

Urban Birth, Urban Living, and Work Migrancy: Differential Effects on Psychotic Experiences Among Young Chinese Men

BACKGROUND: Urban birth and urban living are associated with increased risk of schizophrenia but less is known about effects on more common psychotic experiences (PEs). China has undergone the most rapid urbanization of any country which may have affected the population-level expression of psychosis. We therefore investigated effects of urbanicity, work migrancy, and residential stability on prevalence and severity of PEs. METHODS: Population-based, 2-wave household survey of psychiatric morbidity and health-related behavior among 4132 men, 18-34 years of age living in urban and rural Greater Chengdu, Sichuan Province, China. PEs were measured using the Psychosis Screening Questionnaire. RESULTS: 1261 (31%) of young men experienced at least 1 PE. Lower levels of PEs were not associated with urbanicity, work migrancy or residential stability. Urban birth was associated with reporting 3 or more PEs (OR: 1.63; 95% CI: 1.25-2.11), after multivariable adjustment, with further evidence (P = .01) this effect was restricted to those currently living in urban environments (OR: 1.78; 95% CI: 1.16-2.72). Men experiencing a maximum of 5 PEs were over 8 times more likely to have been born in an urban area (adjusted odds ratio [AOR] 8.81; 95% CI 1.50-51.79). CONCLUSIONS: Men in Chengdu, China, experience a high prevalence of PEs. This may be explained by rapid urbanization and residential instability. Urban birth was specifically associated with high, but not lower, severity levels of PEs, particularly amongst those currently living in urban environments. This suggests that early and sustained environmental exposures may be associated with more severe phenotypes
