Psychopathy and Mortality

COVID-19 prevention behaviour is differentially motivated by primary psychopathy, grandiose narcissism and vulnerable Dark Triad traits

Dark Triad traits (psychopathy, narcissism) are associated with nonadherence to COVID-19 prevention measures such as social distancing and wearing face masks, although the psychological mechanisms underpinning this relationship remain unclear. In contrast, high threat-sensitivity may motivate compliance, and maybe seen in relation to vulnerable dark traits (secondary psychopathy, vulnerable narcissism and borderline personality disorder). The relationship between vulnerable dark traits and COVID-19 prevention behaviour has not been examined. During April 2021, participants (n = 263) completed an online psychometric study assessing engagement with COVID-19 prevention behaviour, traditional DT traits (primary psychopathy; grandiose narcissism) and vulnerable DT traits. Potential indirect effects were fear of COVID-19, perceived coronavirus severity, belief in COVID-19 conspiracy theories and altruism. Model of path analysis identified predictors of engagement in disease prevention behaviour. Primary psychopathy, grandiose narcissism, secondary psychopathy and BPD were associated with less COVID-19 prevention behaviour, with an indirect effect of reduced coronavirus severity. Grandiose narcissism and BPD were also motivated by COVID-19 conspiracy theories, and increased prevention behaviour when fear of COVID-19 was higher. No direct or indirect effects were observed for vulnerable narcissism. The current study is the first to elucidate psychological mechanisms linking vulnerable dark traits with COVID-19 prevention behaviour.

Psychopathic Traits Are Associated with Lifetime History of Nicotine Dependence among Incarcerated Offenders

Background: Individuals scoring high on psychopathy engage in problematic patterns of alcohol and illicit substance use. However, our understanding regarding the association between psychopathy and nicotine use remains limited, which is surprising, given the detrimental consequences associated with such use. Previous studies have observed significant correlations between psychopathic traits (particularly Factor 2 scores assessing lifestyle/behavioral and antisocial traits from the Psychopathy Checklist - Revised [PCL-R]) and increased frequency of nicotine use. However, no study has investigated whether individuals scoring high on psychopathy are characterized by problematic patterns of nicotine use, including lifetime history of nicotine dependence.Objectives: The current study aimed to address this gap, specifically investigating whether PCL-R scores were associated with higher total scores from the Fagerström Test for Nicotine Dependence (FTND).Results: Across both incarcerated men and women, PCL-R total, Factor 2, and Facet 3 (measuring lifestyle/behavioral psychopathic traits) scores were positively correlated with FTND total scores. Additionally, across both samples, hierarchical linear regression analyses revealed these same psychopathy scores remained associated with higher FTND total scores when controlling for additional covariate measures (e.g., age, severity of alcohol and illicit substance use, race, ethnicity, and IQ).Conclusions/Importance: Though associated with small effect sizes, our results support the notion that lifestyle/behavioral psychopathic traits represent a general risk factor for engaging in risky behavior associated with deleterious health consequences, including nicotine use. Our results hold implications for the development of treatment approaches, designed to reduce problematic levels of substance use among individuals scoring high on psychopathy.

A Double-Track Pathway to Fast Strategy in Humans and Its Personality Correlates

The fast-slow paradigm of life history (LH) focuses on how individuals grow, mate, and reproduce at different paces. This paradigm can contribute substantially to the field of personality and individual differences provided that it is more strictly based on evolutionary biology than it has been so far. Our study tested the existence of a fast-slow continuum underlying indicators of reproductive effort-offspring output, age at first reproduction, number and stability of sexual partners-in 1,043 outpatients with healthy to severely disordered personalities. Two axes emerged reflecting a double-track pathway to fast strategy, based on restricted and unrestricted sociosexual strategies. When rotated, the fast-slow and sociosexuality axes turned out to be independent. Contrary to expectations, neither somatic effort-investment in status, material resources, social capital, and maintenance/survival-was aligned with reproductive effort, nor a clear tradeoff between current and future reproduction was evident. Finally, we examined the association of LH axes with seven high-order personality pathology traits: negative emotionality, impulsivity, antagonism, persistence-compulsivity, subordination, and psychoticism. Persistent and disinhibited subjects appeared as fast-restricted and fast-unrestricted strategists, respectively, whereas asocial subjects were slow strategists. Associations of LH traits with each other and with personality are far more complex than usually assumed in evolutionary psychology.

Female Psychopathy and Mortality

The mortality of female psychopaths has scarcely been investigated. To estimate the association between psychopathy and mortality, data from subjects having been in forensic psychiatric assessments at Niuvanniemi Hospital during 1984-1993 were linked to the data from the National Death Registry. Sixteen psychopathic females scoring 25 points or higher in the PCL-R scale (psychopaths) were followed up for a median (IQR) 21 (17-25) years and 41 offenders scoring <25 on the PCL-R (non-psychopathic offenders) for 22 (17-25) years. In both psychopath and non-psychopath offender groups, the mortality was significantly higher (p < 0.01) than in the general population, being over 12-fold among psychopathic and over 6-fold among the non-psychopathic offenders.

Psychopathy

Psychopathy is a personality disorder characterized by a constellation of affective, interpersonal, lifestyle and antisocial features whose antecedents can be identified in a subgroup of young people showing severe antisocial behaviour. The prevalence of psychopathy in the general population is thought to be ~1%, but is up to 25% in prisoners. The aetiology of psychopathy is complex, with contributions of both genetic and environmental risk factors, and gene-environment interactions and correlations. Psychopathy is characterized by structural and functional brain abnormalities in cortical (such as the prefrontal and insular cortices) and subcortical (for example, the amygdala and striatum) regions leading to neurocognitive disruption in emotional responsiveness, reinforcement-based decision-making and attention. Although no effective treatment exists for adults with psychopathy, preliminary intervention studies targeting key neurocognitive disturbances have shown promising results. Given that psychopathy is often comorbid with other psychiatric disorders and increases the risk of physical health problems, educational and employment failure, accidents and criminality, the identification of children and young people at risk for this personality disorder and preventative work are important. Indeed, interventions that target the antecedents of psychopathic features in children and adolescents have been found to be effective.

Personality traits and male vulnerability to commercial sexual exploitation victimisation

BACKGROUND

There has been little research into whether personality traits increase vulnerability to serious forms of recurring victimisation, such as commercial sexual exploitation of young people.

AIMS

To investigate whether impulsivity, emotional dysregulation or high psychopathy scale scores indicative of personality traits increase vulnerability to commercial sexual exploitation.

METHODS

Data were used from the longitudinal Pathways to Desistance Study 1170 justice-involved men who were aged 14-19 at baseline data collection. Ninety-eight (8%) reported having been commercially sexually exploited during adolescence or young adulthood. We investigated whether personality traits measured at baseline were related to such victimisation.

RESULTS

Results of binomial logistic regression among the young men in this sample indicated that Factor 1 scores on the Psychopathy Checklist-Youth Version (PCL-YV), reflecting affective and interpersonal features, are associated with having been commercially sexually exploited, while impulsivity, emotional dysregulation and Factor 2 PCL-YV, reflecting antisocial activities, were not. Having been a victim of other violence and being a member of a cultural or ethnic minority group were also independently related to being exploited.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Our findings show that individual differences in personality, such as fearless temperament and boredom susceptibility, could differentially disadvantage young people, and put them at greater risk of commercial sexual exploitation. This knowledge could be beneficial to prevention efforts supporting male adolescents at risk for victimisation by commercial sexual exploitation, and to shed new light on the theoretical understanding of vulnerability to it.
