Psychopathy and Female Gender: Phenotypic Expression and Comorbidity; A Study Comparing a Sample of Women Hospitalized in Italy's Maximum Security Facility with Women Who were Criminally Sentenced and Imprisoned,

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.     

Psychopathic traits in Finnish homicide offenders with schizophrenia

There is a paucity of studies examining psychopathy in comparable samples of violent individuals with and without psychotic illness. The main goal of the study was to assess the prevalence and nature of psychopathic traits as measured by PCL-R among Finnish homicide offenders with schizophrenia. Further, the impact of co-morbid psychopathy on the homicidal incidents, as well as the associations of psychopathy and offender background factors, among offenders with schizophrenia was investigated.A retrospective study was performed using extensive forensic psychiatric evaluation reports and crime reports as sources of information. The sample consisted of 72 homicide offenders with schizophrenia and 72 controls without psychotic illness.Psychopathic features were prevalent among Finnish homicide offenders with schizophrenia, although for the most parts to a lesser extent compared to other homicide offenders. Like non-mentally ill psychopathic offenders, offenders with schizophrenia and many psychopathic traits are likely to present early starting problems in many areas of life and they also commit homicides that resemble other psychopathic offenders' in their choice of victims, intoxication and post-offense behavior.The observed prevalence of psychopathic traits highlights the importance of psychopathy assessment among violence-prone individuals with schizophrenia. In most respects, offenders with schizophrenia and high levels of psychopathic traits seem to be similar to psychopathic offenders without psychotic illness, which has implications for early intervention and management.     

A Rorschach investigation of incarcerated female offenders with antisocial personality disorder

Although male psychopathy has been linked to histrionic, narcissistic, and antisocial personality disorders (ASPD), less is known about female psychopathy. The Psychopathy Checklist-Revised (PCL-R) and the Rorschach were used to explore the personality functioning of 45 incarcerated female offenders with ASPD delineated by their psychopathy level. Psychopaths (PCL-R > or = 30) and nonpsychopaths (PCL-R < 24) were compared on Rorschach measures of self-perception, interpersonal relatedness, and reality testing. Compared to female offenders with ASPD who were nonpsychopathic, female offenders with ASPD who were psychopathic exhibited marked disturbances in self-perception, interpersonal relatedness, and reality testing. Our findings highlight the heterogeneity of the ASPD diagnosis in women, support the utility of the psychopathy construct with female offenders, and implicate important differences between men and women with ASPD. These gender differences have relevance to the evaluation (PCL-R scoring) and treatment of female offenders. Our findings are discussed within the context of the female psychopath's hypothesized hysterical character style.     

Psychopathy and Mortality

It is not known how mortality differs between psychopathic and nonpsychopathic individuals. We linked data from subjects having been in forensic mental examinations at Niuvanniemi Hospital during 1984–1993 to the data from the National Death Registry to estimate the association between psychopathy and mortality. One hundred psychopathic individuals scoring 25 or higher in the PCL‐R scale were followed up for 20–30 years. Two control groups were used as follows: 178 offenders scoring less than 25 on the PCL‐R, and sample of general population drawn from the Finnish National Statistics database. Results reveal that psychopaths die younger than the general population, and the causes of death are more violent than in the nonpsychopath control group. There was a significant positive correlation between PCL‐R score and mortality, and the mortality among psychopaths was about fivefold when compared with general population.     

The impact of pre-treatment responsivity and treatment participation on violent recidivism in a violent offender sample

This study assessed whether pre-treatment responsivity (psychopathy, motivation to attend treatment, denial and minimisation of offending behaviour, and feelings of guilt or shame) predicted violent recidivism and/or moderated the effectiveness of a violence intervention programme. Participants were 114 male violent offenders who were referred to a structured violent offender group treatment programme; 84 offenders commenced the programme. Results showed that treatment completion did not have a significant main effect on recidivism but that psychopathy scores moderated the effects of treatment. Offenders with high scores on the Psychopathy Checklist: Screening Version (PCL:SV) who were rated as having good engagement with treatment, or who completed treatment, had similar violent recidivism rates compared to offenders with low PCL:SV scores. In contrast, offenders with high PCL:SV scores who dropped out of treatment or were poorly engaged had significantly higher rates of violent recidivism. These findings indicate that treatment effectiveness could be enhanced, and greater reductions in recidivism achieved, if programmes find ways to engage and maintain psychopathic offenders in treatment.     

Psychopathy and deception detection using indirect measures

Purpose. The goal of the current study was to examine psychopathy and indirect measures of deception detection. Methods. Undergraduate students (N=444) viewed video clips of adult male offenders telling true and false stories about crimes. For each story, participants rated indirect measures of deception (thinking hard, nervousness, emotional arousal, and attempting to control behaviour) and credibility. Participants also chose the story they believed to be true and rated the confidence in their decision. Offenders were rated on the psychopathy checklist – revised. Results. Consistent with past research, deception detection accuracy was at chance level and unrelated to confidence. Ratings on indirect measures by undergraduates did not distinguish true and false statements in offenders. Psychopathic offenders were less successful at deception than non‐psychopathic offenders. Psychopathic traits were associated with lower perceived credibility during deception and ratings of thinking harder while lying. Conclusions. The results suggest that indirect measures of deception detection may be less useful in offender samples. Further, the findings are consistent with the general inability of psychopathic offenders to demonstrate superior deception skills in empirical studies. Indirect measures of deception uniquely related to psychopathic traits offer new insight into the relationship between psychopathy and deception.     

Psychopathic personality traits,intelligence, and economic success

A wealth of research has revealed that psychopathy and psychopathic personality traits are associated with criminal involvement. Comparatively less research, however, has examined whether psychopathic personality traits influence economic outcomes in adulthood. The current study addresses this gap in the literature by analyzing data drawn from the National Longitudinal Study of Adolescent Health. The results of the analyses indicate that psychopathic personality traits are negatively related to a number of economic outcomes, including household income and employment history measures. Individuals with high levels of psychopathic personality traits were found to have lower household incomes and to be fired more frequently than individuals with lower levels of psychopathic personality traits. Unexpectedly, psychopathic personality traits were also found to be negatively associated with household debt. There was also some evidence that the effect of psychopathic personality traits was moderated by intelligence in the prediction of household income. We discuss what these findings mean for the psychopathy and economics literatures.     

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 behavior, 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.     

Preliminary Data on the Role of Emotional Intelligence in Mediating the Relationship Between Psychopathic Characteristics and Detention Terms of Property Offenders

We present preliminary data on the role of emotional intelligence (EI) in mediating the relationship between psychopathy and detention term of authors of property crimes. We assumed that the detention term is an approximation of the severity of criminal behavior. A sample of 24 property offenders were individually administered a brief anamnestic interview, the Psychopathic Personality Inventory—Revised (PPI‐R), and the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT). Information concerning the detention term was obtained from prison records. A mediation model was applied to the data showing that offenders high in psychopathic traits (i.e., total PPI‐R score and Self‐centered dimension of PPI‐R) have a low level of ability EI and this is in turn negatively associated with the duration of their prison sentence. Results encourage the investigation of ability EI as a protective factor against the antisocial outcomes of psychopathic disorder.     

Does the three-factor model of psychopathy identify a problematic subgroup of young offenders?

The present study tests the utility of the personality-based three-factor model of psychopathy according to the Hare Psychopathy Checklist: Screening Version (PCL:SV). This model of psychopathy excludes aspects of criminal behavior as opposed to other models of psychopathy. The main research question was to what extent the three-factor model of psychopathy can identify a problematic subgroup of young offenders. The sample consisted of 148 incarcerated young male criminal offenders, between 15 and 25 years of age (mean=19.07, SD=2.11) who were recruited from a central detention center for young offenders in a northern German county. Model-based cluster analysis of the three psychopathy factors showed that three different clusters labeled: (i) Unemotional/Impulsive-Irresponsible, (ii) Low traits, and (iii) Psychopathic personality, had the best fit to the data. The psychopathic personality cluster with high scores on all three factors of the PCL:SV exhibited, as expected, a significantly higher prevalence of conduct disorder and substance use problems, but was not significantly different from the other clusters on past criminality and previous incarcerations. In conclusion, the results showed that the three-factor model of psychopathy can be useful in identifying a problematic subgroup of young offenders.     

Crime profiles and conditional release performance of psychopathic and non‐psychopathic sexual offenders

Purpose. This study investigated the influence of psychopathy and sex offender subtype on criminal history, probability of being granted conditional release, and performance while on conditional release in a diverse group of violent offenders. We predicted that psychopathic sexual offenders would be associated with relatively prolific violent and sexual offending, a high probability of successful conditional release applications despite their past behaviour (resulting from ‘putting on a good show’ in a parole hearing), and poor performance in the community. Methods. Information was gathered via a correctional file review of 310 Canadian male federal offenders. Offenders were categorized into groups based on their sexual offence history (non‐sex offender, rapist, child molester, or mixed rapist/molester) and Psychopathy Checklist – Revised (PCL‐R; Hare, 2003) ratings. Their offences (sexual, violent, or non‐violent) and their complete conditional release histories were coded. Results. Psychopathy was associated with more violent and non‐violent, but not sexual, offences. A significant interaction between psychopathy and offender subtype revealed that psychopathy was associated with a greater number of sex offences within child molesters. High‐psychopathy offenders (both sexual and non‐sexual offenders) were about 2.5 times more likely to be granted conditional release than non‐psychopathic offenders. Conclusions. Psychopathy is associated with more prolific sexual offending among child molesters and – despite their extensive criminal histories and high recidivism rate – a great proficiency in persuading parole boards to release them into the community. Specialized education and training in dealing with psychopathic offenders is urgently needed.     

Examining the relationships between sub-clinical psychopathic traits with shame,guilt and externalisation response tendencies to everyday transgressions

Although many theories of psychopathy include reference to some form of emotional deficit, surprisingly little research has examined the relationships between psychopathic traits and important self-conscious moral emotions such as shame and guilt. The present study sought to examine these relationships in a sub-clinical sample, taking into account the important theoretical differences between the two emotions. Participants (N = 739) completed a measure of psychopathic traits and a measure of self-conscious affect style. Both primary and secondary psychopathic traits were found to be inversely related to guilt-proneness; however, the effect size was greater for primary psychopathic traits. Primary psychopathic traits were unrelated to shame-proneness, while secondary psychopathic traits were positively related to shame-proneness. Both primary and secondary traits were positively related to externalisation; however the effect size was greater for primary over secondary traits. The findings provide support for affective differences between psychopathy variants.     

Psychopathy and intelligence in high-risk violent women

There has been a longstanding debate and mixed evidence on the link between psychopathy and intelligence. Most of the existing research comes from male prisoners, with the literature on female psychopathy and intelligence remaining sparse. Thus, the current study explored the correlational association between psychopathy and intelligence in a sample of high-risk violent female offenders. This is the first study of its kind from the Offender Personality Disorder (OPD) pathway for women in the United Kingdom (UK). The sample includes high-risk violent women presenting with severe personality disorder. In the present study, we conducted a correlational examination between total scores, and the 2-factor and 4-facet structure of the Psychopathy Checklist-Revised (PCL-R) with intelligence using the Wechsler Adult Intelligence Scale (WAIS). No significant associations were found between total PCL-R scores, or factor 2, and intelligence. Positive associations were found between verbal comprehension and factor 1 and the interpersonal facet. Thus, the results suggest high-risk violent female offenders with interpersonal psychopathic traits demonstrate higher levels of verbal comprehension skills. This finding may help explain why psychopathic female offenders, who can be characterized by deceitful and egocentric behaviours, may be able to successfully charm and con others for their own personal gain.     

Relation of Antisocial and Psychopathic Traits to Suicide-related Behavior Among Offenders

Offenders with antisocial traits are relatively likely to attempt suicide, largely because they are more likely to have high negative emotionality and low constraint. Among 682 male offenders, we tested whether negative emotionality, low constraint, and also substance use problems mediated any relationship between antisocial personality disorder (ASPD) and psychopathy on the one hand, and suicide-related behavior (SRB) and ideation on the other. ASPD and the impulsivity/lifestyle features of psychopathy weakly predicted SRB. High negative emotionality and low constraint (but not substance use) mediated the relation between ASPD and SRB. Impulsivity/lifestyle features of psychopathy retained an independent predictive effect. Self-report psychopathy measures added unique predictive variance to the Psychopathy Checklist—Revised. We discuss implications for suicide risk assessment and prevention.

The Intergenerational Cycle of Criminality—Association with Psychopathy*

Abstract: Preventive interventions early in life are likely to lower the risk of intergenerational transmission of criminal behavior. We investigated if psychopathy among homicidal offenders is associated with criminal offending among the offenders’ offspring. The basic sample consisted of consecutive Finnish homicide offenders (during 1995–2004) who had been subjected to a forensic psychiatric examination and rated for a file‐based PCL‐R, and their offspring. Criminal behavior among both genders of the offspring was more common than in the general population. In general, the offspring’s crimes against others (e.g., threat, intimidation, deprivation of freedom, breach of domicile) were associated with their parent’s psychopathy. A grandfather’s major mental disorder was associated with a high rate of crime committed by the offspring. Especially, the sons of male psychopathic homicidal offenders had the highest rate of committing crimes, which was often expressed as vandalism. However, both genders of offspring seem to require special preventive programs to ameliorate these problems.     

Are There Ethnic Differences in Levels of Psychopathy? A Meta-Analysis

Although considerable research on psychopathy has been conducted over the past 30 years, relatively few studies have examined key issues related to potential ethnic differences in this constellation of socially maladaptive personality traits. Given recent sociopolitical and scientific developments, an issue of considerable debate is whether Black individuals possess "more" traits of psychopathy than do Whites. To address this issue, a meta-analysis of differences between these groups' scores on the Psychopathy Checklist--Revised (PCL-R; Hare, 1991) was performed, using 21 studies (N = 8,890) of correctional, substance abuse, and psychiatric samples. Blacks exceeded Whites by an average of less than 1 point on the PCL-R total score. Effect sizes for core interpersonal and affective traits of psychopathy (Factor 1) were sufficiently homogeneous to clearly interpret, although other features manifested statistically significant heterogeneity. Our finding that Blacks and Whites do not meaningfully differ in their levels of core psychopathic traits is consistent with community-based findings for self-report measures of psychopathy and clinical diagnoses of antisocial personality disorder.     

Psychopathy among prisoners in England and Wales

Most research into psychopathy among prisoners is based on selected samples. It remains unclear whether prevalences are lower among European populations. This study aimed to measure the prevalence of psychopathy, and the distribution and correlates of psychopathic traits in a representative national sample of prisoners. Psychopathy was measured using the revised Psychopathy Checklist (PCL-R) in a second stage, cross-sectional survey of prisoners in England and Wales in 1997 (n = 496). Poisson regression analysis was carried out to examine independent associations between correlates and PCL-R total and factor scores. The prevalence of categorically diagnosed psychopathy at a cut off of 30 was 7.7% (95%CI 5.2–10.9) in men and 1.9% (95%CI 0.2–6.9) in women. Psychopathic traits were less prevalent among women. They were correlated with younger age, repeated imprisonment, detention in higher security, disciplinary infractions, antisocial, narcissistic, histrionic, and schizoid personality disorders, and substance misuse, but not neurotic disorders or schizophrenia. The study concluded that psychopathy and psychopathic traits are prevalent among male prisoners in England and Wales but lower than in most previous studies using selected samples. However, most correlates with psychopathic traits were similar to other studies. Psychopathy identifies the extreme of a spectrum of social and behavioral problems among prisoners.     

The attribution of blame and type of crime committed: transcultural validation.

This study examines the relationship between type of offence and the attributions offenders make about their criminal act. The subjects were 98 Icelandic criminals who had completed the Gudjónsson Blame Attribution Inventory. Significant differences in attribution were found between offender groups. Sex offenders and those who had committed acts of interpersonal violence reported most guilt about their offence and they attributed cause for their offence more to mental factors (eg, loss of self-control) than other types of offender. Violent offenders had the highest external attribution and sex offenders the lowest. The findings with regard to the three attributions are remarkably similar to those found previously for British offenders.     

A multidimensional scaling analysis of the Hare PCL-R: Unfolding the structure of psychopathy

Abstract

Recent studies examining the Psychopathy Checklist – Revised (PCL-R) have argued for a range of factorial solutions to describe and explain the dimensions of psychopathy. This study details an empirical analysis of North American PCL-R data for 4630 male offenders, using multidimensional scaling (MDS) as a non-linear alternative to factor analysis. The emergent structure of Hare's psychopathy psychometric can be interpreted in more than one way and at different levels of specificity. The multidimensional scalograms reveal a set of facets consistent with the two- and four-factor solutions that emerge from the same data. Equally the structure of the PCL-R can be interpreted through personality theory as a set of core traits and behavioural manifestations, consistent with an evolutionary basis for psychopathic tendencies. These analyses provide support for a multidimensional structure within the PCL-R, and suggest that psychopathy can be viewed as an extreme variant of multiple dimensions of personality.
