Sex and Sexual Orientation Differences in Dark Triad Traits, Sexual Excitation/Inhibition, and Sociosexuality

The present study sought to investigate sex and sexual orientation differences in several traits related to sexuality and sexual behavior. Examining sexual orientation differences alongside basic sex differences to help identify correlates of sexual orientation diversity, and whether individuals with varying degrees of same-sex attraction show concurrent sex-atypical shifts in other domains. Males tend to score higher than females in the Dark Triad (DT) traits of sub-clinical narcissism, psychopathy, and Machiavellianism. Similarly, females tend to be more cautious than males in their attitudes and desires toward casual sex activity (i.e., sociosexuality). These sex differences may be related to the propensity for individuals to become easily sexually excited, which is higher in males, or to instead inhibit sexual arousal, which is higher in females. In a large undergraduate sample (N = 2047), we replicated expected sex differences in DT traits, sociosexuality, and sexual excitation/inhibition. We found that non-heterosexual females were "male-shifted" in some of these traits, but these shifts tended to be strongest among mostly heterosexual and bisexual individuals. Furthermore, we found that within-sex variation in sociosexuality, sexual excitation, and sexual inhibition was not related to sexual orientation in a linear fashion. Instead, sociosexuality and sexual excitation were related to sexual orientation in a curvilinear (inverted-U) fashion, especially among females. The fact that traits correlated with bisexuality and homosexuality were somewhat distinct is consistent with the idea that different developmental pathways may lead to these discrete sexual attraction patterns.

Marital quality improves self- and partner-reported psychopathy among Chinese couples: A longitudinal study

BACKGROUND

Psychopathy is closely related to many negative interpersonal outcomes in daily life, including violence. Therefore, psychopathy intervention in subclinical individuals has significant application value.

OBJECTIVE

Guided by the personality-relationship transaction model and social investment theory, this study examined how marital quality affects self- and partner-rated psychopathy. We also used the actor-partner interdependence mediation model to explore the mediating effect of communication.

METHODS

We examined self-reports and partner reports of psychopathy, marital quality, and communication among 260 married Chinese couples.

RESULTS

The results indicated that marital quality directly influenced couples' self-rated psychopathy, with both actor and partner effects on husbands' psychopathy and actor effects on wives' psychopathy. Moreover, verbal communication had mediating effects at time 2 between marital quality at time 1 and partner-reported psychopathy at time 3. Meanwhile, the mediating effect of nonverbal communication was not significant.

CONCLUSION

Our investigation of relationship effects on psychopathy revealed that the underlying mechanisms differed between self- and partner-rated psychopathy. The findings can highlight directions for exploring potential intervention strategies for subclinical psychopathy.

Substance use in the correctional settings: A qualitative exploration of individual and contextual characteristics and intervention strategies using the behavior change wheel framework

BACKGROUND AND OBJECTIVES

Planning and implementing prison-based substance use disorder (SUD) interventions are challenging. We wanted to understand why and how people in correctional settings (CS) use drugs and to explore what policies, environmental, and interpersonal factors influence substance use among incarcerated people. Using the Behavior Change Wheel (BCW) framework, we proposed a thematic map with intervention functions to reduce substance use in CS.

METHODS

We used the Framework Method of qualitative analysis. We did snowball sampling for the incarcerated people with drug use (PWD) and convenience sampling for the staff. The in-depth interview sample comprised 17 adult PWD, three prison administrative, and two healthcare staff. We determined the sample size by thematic data saturation. We followed a mixed coding approach for generating categories, i.e., deductive (based on the BCW framework) and inductive. The study constructed the final theoretical framework by determining the properties of the categories and relationships among the categories.

RESULTS

We identified eleven categories aligned with the BCW framework. The themes were prison routine, interpersonal dynamics of the incarcerated population, exposure to substance use, attitude of staff towards PWD, experience with prison healthcare, willingness (to reduce drug use) and coping, compassion, drug use harms, conflict between staff and residents, stigma, and family/peer support. The BCW framework aided the identification of potential intervention functions and their interactions with the organizational policies that could influence PWD's capability-opportunity-motivation (COM) and drug use behavior (B).

CONCLUSION

There is a need to raise awareness of SUD prevention and intervention among decision-makers and revisit the prison policies.

When it's not safe to be me: employee authenticity mediates the effect of perceived manager psychopathy on employee well-being

BACKGROUND

Psychopathy in managers is often measured on global scales and associated with detrimental outcomes for subordinates, such as bullying and reduced well-being. Yet some features of psychopathy, like boldness, appear to have beneficial outcomes. Using the triarchic model of psychopathy, we differentiate between adaptive and maladaptive traits in managers and model their effects on employee engagement and burnout. In addition, we test the extent to which authenticity, known to ameliorate the effect of some negative experiences on well-being, might mediate the influence of managers' perceived psychopathic traits on employee well-being.

METHODS

In a two-wave study, full-time employees (N = 246) reported on their manager's psychopathic traits (boldness, meanness, disinhibition), their own authenticity and, six weeks later, their engagement and burnout.

RESULTS

In support of our hypotheses, manager boldness enhanced engagement and reduced burnout while meanness and disinhibition reduced engagement and increased burnout. Additionally, employee authenticity was a partial mediator of the effect of managerial psychopathy on engagement and burnout.

CONCLUSIONS

Perceived psychopathic traits in managers have the potential to influence whether employees feel able to be their authentic selves at work, which consequently affects their well-being. A work culture that values authenticity can directly improve well-being and help employees to deal with managerial behaviour that stems from maladaptive psychopathic traits. We also highlight the importance of discriminating between constituent psychopathic traits to identify the potentially adaptive nature of the boldness element of psychopathy.

How Does Abusive Supervision Affect Organisational Gossip? Understanding the Mediating Role of the Dark Triad

According to the trait activation theory (TAT), personality characteristics are dormant until contextual elements stir them into action. Personality traits are expected to be activated in the context of abusive supervision. From this perspective, our paper examines whether abusive supervision affects organisational gossiping behaviour through the dark triad. To this end, this study examines the mediating effects of the dark triad on the relationship between abusive supervision and organisational gossip based on cross-sectional data gathered from two separate samples. Using the results from structural equation modelling, it is evident that abusive supervision activates the dark triad, and its context influences organisational gossip in line with the TAT. In addition, our results show that abusive supervision positively affects gossip for information gathering and relationship building, with the dark triad proving to be completely mediating. This finding implies that abusive supervision is a contextual factor, and as such, behaviours such as consistent ill treatment and non-violent, verbal or non-verbal hostile acts will have long-term and lasting effects on organisational communication in many organisations. This study offers significant policy implications concerning behavioural issues within education-centred organisations.

Psychopathic Traits in a Swedish Court-Ordered Forensic Sample: Preferential Associations of Boldness, Meanness, and Disinhibition

The construct validity of the triarchic psychopathy model has yet to be evaluated in the Swedish forensic psychiatric context. We examined associations between the three phenotypic constructs of the triarchic model of psychopathy (i.e., boldness, meanness, disinhibition), self-assessed empathy and anxiety, and clinical variables in 91 individuals undergoing pretrial forensic psychiatric evaluation in Sweden. Participants completed the Triarchic Psychopathy Measure (TriPM) and self-report measures of empathy and anxiety. Clinical variables, including psychiatric diagnoses and criminal behavior, were collected from the forensic psychiatric evaluations (FPE). All three subscales of the TriPM displayed significant and predominantly anticipated correlations with empathy and trait anxiety measures. TriPM Disinhibition was the only subscale with significant associations with the clinical variables collected from the FPEs. The results provide evidence for the reliability and construct validity of the Swedish translation of the TriPM in a pretrial forensic setting.

Dissociating cognitive and affective empathy across psychopathy dimensions: The role of interoception and alexithymia

This study examined the associations between psychopathy dimensions (triarchic phenotypes and classical factors), empathy domains (cognitive and affective), and interoception (interoceptive attention and accuracy) while accounting for the putative role of alexithymia. A community sample (n = 515) completed an online survey encompassing: Triarchic Psychopathy Measure (boldness, meanness, disinhibition); Levenson Self-Report Psychopathy Scale (primary and secondary psychopathy); Body Perception Questionnaire (interoceptive attention); Interoceptive Accuracy Scale; Toronto Alexithymia Scale. Hierarchical linear regression models were implemented for hypothesis-driven analyses examining the associations between psychopathy, empathy, and interoception while controlling for sex, age, and alexithymia. Exploratory path models were employed to investigate alexithymia and/or cognitive empathy as mediators between interoception and psychopathy. Our results largely confirmed the postulated empathy profiles across psychopathy dimensions, as meanness and primary psychopathy displayed a broad empathy impairment, while disinhibition and secondary psychopathy were only associated with diminished cognitive empathy. Importantly, boldness displayed a unique pattern (enhanced cognitive empathy and reduced affective empathy), further reinforcing its importance within the constellation of psychopathy traits. Contrary to our hypotheses, self-perceived interoceptive attention and accuracy were not associated with either psychopathy dimension after controlling for alexithymia. However, interoceptive accuracy and alexithymia were associated with cognitive empathy, while alexithymia was also positively related to all psychopathy dimensions (as expected), despite the unexpected strong and negative association with boldness. Exploratory analyses suggested significant indirect effects (mediation) between interoceptive accuracy and psychopathy via alexithymia and/or cognitive empathy. These mediating effects must be interpreted with caution and future studies should be designed to formally test this model.

Psychopathic Traits and Utilitarian Moral Judgment Revisited

To provide deeper insights into the relationships between psychopathic traits and utilitarian moral judgment, we studied N = 702 adults using three psychopathy scales: (a) the Levenson's Self-report Psychopathy Scale; (b) the Psychopathic Personality Inventory; and (c) the Triarchic Psychopathy Measure; and three measures of utilitarian moral judgment: (a) trolley dilemmas; (b) the Consequences, Norms, and Inaction (CNI) model of moral decision-making; and (c) the Oxford Utilitarianism Scale. When using the traditional approach to moral judgment (i.e., trolley dilemmas, instrumental harm, traditional score from the CNI model), we found that higher levels of psychopathic traits were associated with a higher utilitarian tendency. When using the modeling approach, we found that a higher level of psychopathic traits was related to weaker sensitivity to moral norms and less action averse in morally problematic situations. In addition, we found negative associations between impartial beneficence and all psychopathy scores.

Neurorehabilitation of Offenders, Consent and Consequentialist Ethics

The new biotechnology raises expectations for modifying human behaviour through its use. This article focuses on the ethical analysis of the not so remote possibility of rehabilitating criminals by means of neurotechnological techniques. The analysis is carried out from a synthetic position of, on the one hand, the consequentialist conception of what is right and, on the other hand, the emphasis on individual liberties. As a result, firstly, the ethical appropriateness of adopting a general predisposition for allowing the neurorehabilitation of prisoners only if it is safe and if they give their consent will be defended. But, at the same time, reasons will be given for requiring, in certain circumstances, the exceptional use of neurotechnology to rehabilitate severely psychopathic prisoners, even against their will, from the same ethical perspective.

Attention-affect interactions and triarchic psychopathy: New electrophysiological insights from the late positive potential

One of the most prominent characteristics of psychopathy is a reduced processing of emotionally relevant information. However, it is still unclear how attentional mechanisms may modulate this deficit. The current study aimed to examine the impact of attentional focus on emotion processing in relation to the triarchic constructs of boldness, meanness, and disinhibition. Participants performed two tasks in which pleasant, neutral, and unpleasant framed pictures were presented. In the first task, participants were required to indicate the color of the frame (alternative-focus task), whereas in the second task they were instructed to indicate the emotional category of the image (affect-focus task). The Late Positive Potential (LPP) was used as an index of sustained engagement of attention to affective material. Confirming a successful task manipulation, we observed reduced LPP amplitudes, particularly for affective relevant material, in the alternative-focus task compared to the affect-focus task. Most interestingly, our results evidenced that trait meanness scores were associated with blunted elaborative processing of affective material (both appetitive and aversive) when this information was task-relevant (affect-focus task), but not when it was task-irrelevant (alternative-focus task). These findings indicate that high mean individuals are characterized by blunted elaborative processing of affective stimuli when their motivational relevance is determined in a top-down manner (i.e., when it is task-relevant). Our results highlight the need for further studying of the bottom-up and top-down dynamics of emotional attention in psychopathy.

Psychopathy in Iran: Developing and Validating a Persian Version of the Comprehensive Assessment of Psychopathic Personality- Self-Report (CAPP-SR)

The Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR) is the most recent operationalization of the CAPP model which uses 33 symptoms to conceptualize psychopathic personality disorder. In the current study, we sought to examine the cross-cultural utility of the CAPP-SR in an Iranian sample. In Study 1, we translated the CAPP-SR into Persian and assessed the linguistic convergence between the Persian and original English versions using a sample of Persian–English bilingual university students in New Zealand. In Study 2, we examined the reliability and validity of the Persian CAPP-SR using a sample of university students in Iran. Our results showed that the Persian CAPP-SR has a promising pattern of convergent and incremental validity in terms of their associations with conceptually-relevant criterion measures, including those designed for the Iranian cultural context. Overall, the findings from the current study support the use of the Persian CAPP-SR as well as having implications for the cross-cultural utility of the CAPP model.

Acquiring Psychopathy and Callousness Traits: Examining the Influence of Childhood Betrayal Trauma and Adult Dissociative Experiences in a Community Sample

The study of psychopathy has largely centered on samples of incarcerated offenders with a focus on primary psychopathy traits. Less is known, however, about how experiences of childhood betrayal trauma and dissociation influence the development of these traits in non-institutionalized individuals. In the present study, we utilized structural equation modeling to investigate the relationships among childhood betrayal trauma, adult dissociation, and adult psychopathy traits and callous affect traits in a community sample (N = 746). Childhood betrayal trauma was associated with psychopathy and callous affect traits, and mediated by dissociative experiences. These results are consistent with theory and prior empirical findings associating childhood betrayal trauma with dissociation, psychopathy, and callous affect traits. The results will help influence the design of future studies that can further inform the developmental course of psychopathy.

Psychopathy and dangerousness: An umbrella review and meta-analysis

Psychopathy has traditionally been linked with heightened criminality, but the relationship of psychopathy with increased risk for dangerousness is contested. To address this debated issue, we conducted an umbrella review (PROSPERO CRD42020214761) of all available meta-analyses of psychopathy and indices of 'dangerousness' (e.g., violent or sexual recidivism, self-reported aggression). We searched PsycINFO, Web of Science, PubMed, and Scopus from inception to August 19, 2022, to identify systematic reviews and meta-analyses on psychopathy and dangerousness. Our review included 33 studies, with the quantitative synthesis including 17 effect sizes extracted from 10 studies (N = ∼77,000 participants). Overall, we observed a pooled correlation coefficient r = 0.284 [95% CI = 0.233, 0.336] for the association of psychopathy with dangerousness (equivalent to Cohen's d = 0.592). Despite considerable heterogeneity (I² = 89.9%), leave-one-out analyses had minimal impact. The effect was robust to examination of potential moderators such as study quality and sample ages. However, the relationship was stronger when psychopathy was assessed using self-report compared to clinical rating scales. The association should be interpreted as meaningful in both the short-term and the long-term and suggests that psychopathy is one of the strongest predictors of dangerousness in the realm of psychopathology.

Trajectories of Psychopathic Traits, Anxiety, and Violence Exposure Differentially Predict Antisociality in Legal System-Involved Youth

Psychopathic traits are associated with several forms of antisociality, including criminal offending, legal system involvement, and substance use. Some research suggests that primary (high psychopathic traits, low negative emotions) versus secondary (high psychopathic traits, high negative emotions and/or negative experiences and environments) variants confer different levels of risk for antisociality. However, research has not examined trajectories of co-occurring fluctuations in psychopathic traits, negative emotions, and negative experiences and environments or how trajectory membership relates to antisociality. We implemented group-based multi-trajectory modeling in a sample of 809 justice-involved male (n = 681) and female (n = 128) youth from the Pathways to Desistance Study to address these gaps. We identified four trajectories of co-occurring change in psychopathic traits, anxiety, and violence exposure spanning three years: Low (low levels of each factor); Moderate Psychopathic Traits, High Negative Emotions and Experiences (moderate-decreasing psychopathic traits and high-decreasing anxiety/violence exposure); Potential Primary Psychopathic Traits (elevated-decreasing psychopathic traits, moderate-decreasing anxiety, moderate-stable violence exposure); and High/Secondary Psychopathic Traits (high-stable psychopathic traits, elevated-stable anxiety, high-decreasing violence exposure). Compared to the Low trajectory, all trajectories predicted greater violent crime and substance use three and four years later. Additionally, compared to the Low trajectory, the Potential Primary Psychopathic Traits trajectory predicted more nonviolent offending three years later. Finally, the High/Secondary Psychopathic Traits trajectory showed the most persistent antisociality, predicting more nonviolent crime, higher substance dependence symptoms, and higher likelihood of arrest three and four years later. Youth with co-occurring high psychopathic traits, anxiety, and violence exposure appear most at risk for severe antisociality.

Which Dark Personality Traits Could Predict Insomnia? The Mediated Effects of Perceived Stress and Ethical Judgments

This study aimed to investigate the relationship between dark personality traits and insomnia by considering the mediated effects of perceived stress and ethical judgments. This descriptive and correlational study was conducted with 464 university athlete students from individual and team sports. Dark Triad Scale (DTS), Insomnia Severity Index (ISI), Perceived Stress Scale (PSS), and Moral Content Judgment in Sport Questionnaire (MCJSQ) were used. Significant correlation coefficients were observed between the dark personality traits and other variables. Regression analysis showed that psychopathy (about 19%) and ethical judgments (about 16%) could predict insomnia. It was shown that among dark personality traits, psychopathy along with ethical judgments could predict insomnia.

Situating Psychopathy Within the DSM-5 Alternative Model of Personality Disorders (AMPD) Among Italian Community-Dwelling Adults

Given growing evidence for a joint hierarchical framework of clinical and personality symptomatology, situating triarchic traits within this model would acknowledge transdiagnostic trait-related variance and provide a basis for linking the DSM-5 Alternative Model of Personality Disorders (AMPD) domains to established indicators of these neurobehavioral traits. The current study (N = 2,041 Italian adults) sought to replicate and extend recent evidence regarding the locations of triarchic traits within the AMPD and to examine relations with criterion measures at different levels of the hierarchy. "Bass-ackwards" analyses revealed a hierarchical structure of personality pathology in which triarchic traits aligned with broad dispositional domains of the AMPD. Boldness, meanness, and disinhibition were clearly situated within the Externalizing branch of the hierarchy and helped to differentiate the Negative Affect, Antagonism, Detachment, and Disinhibition domains at lower levels. The current findings support the view of psychopathy as multidimensional and encompassing developmentally meaningful and neurobehaviorally relevant traits.

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits

BACKGROUND

Psychopathic traits involve interpersonal manipulation, callous affect, erratic lifestyle, and antisocial behavior. Though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design.

METHODS

In total, 1842 adult twins from the community reported their current psychopathic traits and experiences of negative parenting during childhood. We fit bivariate genetic models to the data, decomposing the variance within, and the covariance between, psychopathic traits and perceived negative parenting into their genetic and environmental components. We then fit a genotype × environment interaction model to evaluate whether negative parenting moderated the etiology of psychopathic traits.

RESULTS

Psychopathic traits were moderately heritable with substantial non-shared environmental influences. There were significant associations between perceived negative parenting and three of four psychopathy facets (interpersonal manipulation, erratic lifestyle, antisocial tendencies, but not callous affect). These associations were attributable to a common non-shared environmental pathway and not to overlapping genetic effects. Additionally, we found that primarily shared environmental influences were stronger on psychopathic traits for individuals with a history of greater negative parenting.

CONCLUSIONS

Utilizing a genetically-informed design, we found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits. Moreover, perceptions of negative parenting emerged as a clear environmental influence on the development of interpersonal, lifestyle, and antisocial features of psychopathy.

Perceptual similarity of psychopathy and marital quality in Chinese married couples: The mediating role of couple communication

Previous studies have shown that psychopathy, one of the Dark Triad personality traits, is associated with relationship dissatisfaction. However, the similarity of psychopathy among romantic couples remains uncertain with regard to relationship outcomes. This study examined the effect of the perceptual similarity of psychopathy on marital quality in a sample of 245 heterosexual married couples, using intraclass correlation coefficients as the method for assessing couples' similarity. This study also explored the possible mediating role of couple communication based on the Actor-Partner Interdependence model. The results reveal that husbands' self-rating and wives' partner-rating of psychopathy showed negative effects on marital quality, whereas wives' perceptual similarity of psychopathy exerted both actor and partner effects on marital quality via couple communication. The current study enriches the theoretical framework of personality and relationship outcomes and emphasizes the importance of communication in a close relationship.

Perinatal and early-life factors associated with stable and unstable trajectories of psychopathic traits across childhood

BACKGROUND

This study aimed to identify perinatal and early-life factors associated with trajectories of psychopathic traits across childhood.

METHODS

Participants were 1631 children (51.5% girls) from the Quebec Longitudinal Study of Child Development. A wide range of perinatal and early-life factors were assessed from pregnancy to age 2.5 years using medical files and mothers' reports. Psychopathic traits were assessed via teachers' reports at ages 6, 7, 8, 10, and 12 years. Latent class growth analyses and multinomial logistic regressions controlling for child sex were conducted. Two-way interaction effects between perinatal/early-life factors and child sex were explored.

RESULTS

Four trajectories of psychopathic traits were identified: High-stable (4.48%), Increasing (8.77%), Decreasing (11.46%), and Low-stable (75.29%). A few perinatal factors and most child-level and family-level early-life factors significantly increased the odds of following the High-stable v. the Low-stable trajectory. Higher levels of psychotropic exposures during pregnancy, socioeconomic adversity, child's physical aggression, child's opposition, mother's depressive symptoms, and hostile parenting increased the likelihood of following the Increasing instead of the Low-stable trajectory. Higher socioeconomic adversity, mother's depressive symptoms, and inconsistent parenting were associated with membership to the High-stable instead of the Decreasing trajectory. Most associations were not moderated by child sex.

CONCLUSIONS

These results shed light on the perinatal and early-life factors that are associated with specific pathways of psychopathic traits during childhood and suggest that different factors could be targeted to prevent the exacerbation (v. low and stable levels) or the stability at high levels (v. attenuation) of these traits.

Troll story: The dark tetrad and online trolling revisited with a glance at humor

Internet trolling is considered a negative form of online interaction that can have detrimental effects on people's well-being. This pre-registered, experimental study had three aims: first, to replicate the association between internet users' online trolling behavior and the Dark Tetrad of personality (Machiavellianism, narcissism, psychopathy, and sadism) established in prior research; second, to investigate the effect of experiencing social exclusion on people's motivation to engage in trolling behavior; and third, to explore the link between humor styles and trolling behavior. In this online study, participants were initially assessed on their personality, humor styles, and global trolling behavior. Next, respondents were randomly assigned to a social inclusion or exclusion condition. Thereafter, we measured participants' immediate trolling motivation. Results drawn from 1,026 German-speaking participants indicate a clear correlation between global trolling and all facets of the Dark Tetrad as well as with aggressive and self-defeating humor styles. However, no significant relationship between experiencing exclusion/inclusion and trolling motivation emerged. Our quantile regression findings suggest that psychopathy and sadism scores have a significant positive effect on immediate trolling motivation after the experimental manipulation, whereas Machiavellianism and narcissism did not explain variation in trolling motivation. Moreover, being socially excluded had generally no effect on immediate trolling motivation, apart from participants with higher immediate trolling motivation, for whom the experience of social exclusion actually reduced trolling motivation. We show that not all facets of the Dark Tetrad are of equal importance for predicting immediate trolling motivation and that research should perhaps focus more on psychopathy and sadism. Moreover, our results emphasize the relevance of quantile regression in personality research and suggest that even psychopathy and sadism may not be suitable predictors for low levels of trolling behavior.

The Nature and Nurture of Callous-Unemotional Traits

Callous-unemotional (CU) traits, a risk factor for psychopathy, delineate youths with relatively low empathy and guilt, and identify youths with high risk for chronic and severe antisocial behavior (e.g., rule breaking, aggression). We describe work identifying nature and nurture influences on the development of CU traits. Additionally, we clarify the relationship between CU traits and psychopathy, highlight potential misinterpretations of findings on influences of “nature” versus “nurture,” and discuss treatment implications.

Surviving Senior Psychopathy: Informant Reports of Deceit and Antisocial Behavior in Multiple Types of Relationships

A prevailing view among researchers and mental health clinicians is that symptoms of antisocial personality disorder (ASPD)/psychopathy decrease as affected individuals reach middle age. In the current investigation, informants were surveyed about the behavior of individuals who they believed showed traits of ASPD/psychopathy and were over the age of 50. A final sample of 1,215 respondents rated the index individuals according to the ASPD/psychopathy traits derived from the pre-publication first draft of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition, revealing high endorsement of traits associated with ASPD. Survey respondents reported their observations that individuals who met a threshold for putative ASPD/psychopathy continued to engage in antisocial behavior after age 50, and as a result the respondents endured significant harm, including material losses, financial losses, and various self-reported mental health problems. Those who knew the index individuals both before and after the age of 50 were specifically asked whether there was a change in the individual's engagement in manipulation, deceit, and antisocial behavior; 93% of respondents reported that the behavior was just as bad or worse after age 50. Other researchers have suggested that the DSM diagnostic criteria do not accurately describe ASPD/psychopathy symptoms and behavior in older adults, and that the disorder remains stable, but its manifestation changes with age. This study supports those conclusions.

Do Triarchic Psychopathy Components of New Zealand High-Risk Parolees Predict Probation Officer Relationship Quality, Quality of Life on Parole, and Recidivism?

The Triarchic Psychopathy Measure (TriPM) is a self-report scale based on the Triarchic Model that has been little used in research in the criminal justice system. We sought to examine associations between pre-release TriPM components, probation officer relationships, and parolee quality of life, both measured after 2 months in the community, and reconviction 12 months after release. Using data from 234 New Zealand male high-risk prisoners, we tested four multivariate models each across three timepoints. Pre-release, we found Boldness was not predictive, but Meanness predicted poorer relationship quality after 2 months, both from probation officer and parolee perspectives, with the former in turn predicting reconviction within 12 months. Disinhibition predicted 12-month recidivism regardless of relationship quality or external life circumstances. This relationship to recidivism was partially explained in the final model which linked Disinhibition and poorer subjective wellbeing, with the latter in turn predicting recidivism.

The Societal Response to Psychopathy in the Community

The harm usually associated with psychopathy requires therapeutically, legally, and ethically satisfactory solutions. Scholars from different fields have, thus, examined whether empirical evidence shows that individuals with psychopathic traits satisfy concepts, such as responsibility, mental disorder, or disability, that have specific legal or ethical implications. The present paper considers the less discussed issue of whether psychopathy is a disability. As it has been shown for the cases of the responsibility and mental disorder status of psychopathic individuals, we argue that it is undecided whether psychopathy is a disability. Nonetheless, based on insights from disability studies and legislations, we propose that interventions to directly modify the propensities of individuals with psychopathic tendencies should be balanced with modifications of the social and physical environments to accommodate their peculiarities. We also suggest how this social approach in some practical contexts that involve non-offender populations might be effective in addressing some of the negative effects of psychopathy.

Is it good to be bad? An evolutionary analysis of the adaptive potential of psychopathic traits

Although psychopathy is widely conceptualised as a mental disorder, some researchers question the maladaptive nature of psychopathy, and argue that it might be advantageous from an evolutionary point of view. According to this view, psychopathy can be seen as an evolutionary adaptative strategy that relies on deception and manipulation to gain short-term reproductive benefits. Psychopathy is also identified as a fast life strategy in response to early life stress and an adaptation to harsh environments. This paper investigates the evidence that psychopathic traits are adaptive, while also addressing the limitations of current evolutionary models of psychopathy based on frequency-dependent selection and life history theory. We review recent studies on the fitness correlates of psychopathy and find that psychopathic traits present potential adaptive trade-offs between fertility and mortality, and offspring quantity and quality. On a proximate level, individual differences in stress reactivity and environmental risk factors in early development predispose to psychopathy through gene-environment interactions. We propose that environmental, developmental, social and cultural factors can mediate the relationship between psychopathic traits and fitness and therefore should be considered to make accurate predictions on the adaptive potential of psychopathy. We end by outlining gaps in the literature and making recommendations for future evolutionary research on psychopathy.

Examining the Psychometric Properties of the Expanded Levenson Self-Report Psychopathy Scale in Community and University Samples

The aim of the current study was to further examine the psychometric properties of the Expanded Levenson Self-Report Psychopathy Scale (E-LSRP; Christian & Sellbom, 2016). Specifically, its reliability, internal structure, and convergent and discriminant validity were evaluated using university (N = 367) and community samples (N = 205) from Aotearoa New Zealand. The results provided support for the reliability and validity of the E-LSRP in both samples. More specifically, the internal consistency estimates of the E-LSRP were above the meaningful threshold, indicating good reliability. Furthermore, using confirmatory factor analysis, the hypothesized three-factor structure was supported and conceptually consistent with Cooke and Michie's (2001) Psychopathy Checklist-Revised (PCL-R) three-factor model. Lastly, the results generally provided support for the convergent and discriminant validity of the E-LSRP subscales; the E-LSRP Egocentricity was associated with criteria relevant to interpersonal impairment, the Callous scale with criteria relevant to the affective psychopathy domain, and the Antisocial scale with criteria representing behavioral dysfunction. Overall, the E-LSRP is a promising tool for assessing psychopathy in nonincarcerated populations.

Some critical considerations in applying the construct of psychopathy to research and classification of childhood disruptive behavior disorders

The recent inclusion of callous-unemotional traits in the diagnostic criteria for serious conduct problems has led to renewed interest in more comprehensive integrations of the construct of psychopathy into research and clinical classification of childhood disruptive behavior disorders. There have been a number of recent reviews of research focusing the many potential benefits for this integration. However, there are also a number of issues that could reduce these benefits and even potentially lead to harmful effects. The current paper focuses on several of these issues, some of which are common when attempting to integrate research findings across areas that have been conducted independently of each other. Other issues are more specific to the construct of psychopathy. Specifically, the current paper focuses on the lack of agreement on the necessary and sufficient dimensions needed to define psychopathy, the need to consider developmental relationships among these dimensions, the implications of the different associations among the dimensions of psychopathy with conduct problems in children and adolescents, the need to consider how these dimensions relate to existing constructs used in the classification of disruptive behavior disorders, and the potential harmful effects of labeling something "a dimension of psychopathy". These issues have several clear implications for using the construct of psychopathy to guide research on and diagnostic classification of childhood disruptive behavior disorders.

Sex Moderates Reward- and Loss-Related Neural Correlates of Triarchic-Model Traits and Antisocial Behavior

Abnormalities in responses to reward and loss are implicated in the etiology of antisocial behavior and psychopathic traits. While there is evidence for sex differences in neural response to reward and loss, it remains unclear how sex differences may moderate links between these neural responses and the phenotypic expression of antisocial behavior and psychopathic traits. This study examined sex differences in associations of neural response to reward and loss with antisocial personality symptoms and psychopathic traits. Functional neuroimaging data were collected during a monetary incentive delay task from 158 participants. Among males, during loss anticipation, activation in the left nucleus accumbens was negatively associated with antisocial behavior. Among females, during loss feedback, activation in the left nucleus accumbens and left amygdala was negatively associated with antisocial behavior. These results suggest that phenotypic sex differences in psychopathic traits and antisocial behavior may in part be attributable to different etiological pathways.

Scientism, Ethics and Evil: From Mens Rea to Cerebrum Reus

Can criminology thrive on quantitative studies alone? Can evil be operationalized? Quantitative work may have, for the time being, supplanted common sense, personal experience and resulting in an improbable "Periodic Table of humanity". Has the construction of the psychopathic concept surpassed positivist "constitutional" formulations and translated into effective (re)habilitation of individuals lacking affiliative ethical behaviors? Or has it simply fueled a deterministic neo-Lombrosian truism: moral development has a brain. Has it helped so far? Has letting go of fundamental moral concepts, implicit in organized religion - but pervasive in most cultures irrespective of religious affiliation and devotion - in favor of causal explanations based solely on neuroimaging, personality inventories or structured emotional decoding tasks, made a difference in the life - or in the defense for that matter - of wrongdoers diagnosed as intrinsically evil?

Measurement Invariance of the Short Dark Tetrad Across Cultures and Genders

Abstract. The last two decades revealed a plethora of scientific examinations on the Dark Triad (narcissism, psychopathy, Machiavellianism) and Dark Tetrad traits (Dark Triad + sadism) in a variety of contexts. Short scales for the assessment of these traits have been very influential and widely used. Building upon previous research, the 28-item Short Dark Tetrad (SD4) was introduced as a measure for the assessment of the Dark Tetrad traits. A recent study found that the SD4 is invariant across genders, but little is known concerning invariance across cultures. Therefore, we tested measurement invariance (MI) between German and US participants. Additionally, we replicated extant findings on MI across genders. The analyses suggested configural MI across cultures, metric MI between genders in a US sample, and scalar MI across genders in a German sample. To address that the SD4 revealed only a modest fit in the samples, we further computed Exploratory Structural Equation Models. Those were mostly consistent with the original model structure and indicated that adding marginal cross-loadings among the factors accounts for enhanced model fit. Possible explanations for the findings related to MI were discussed.

Youth Serial Killers: Psychological and Criminological Profiles

Serial murder is a specific type of violent crime that falls into the crime category of multicide. According to the nomenclature of the Federal Bureau of Investigation’s Violent Crime Classification Manual and Academic Researchers for the Classification of Violent Crimes, most serial killers are adults. However, serial murder is also committed by young people, although to a lesser extent. Young serial killers are a topic of relevance in areas such as psychology, criminology, and the justice system. Given that the study of the variables that could be the basis of such multicide criminality is not conclusive, the need for further research is evident. The homicides perpetrated by children and young people point to a social panorama that is alarming due to their young age. This issue is prevalent enough to conduct a review. The performed review concludes the importance of psychosocial factors to better understand the process by which children and young people commit crimes as serious as serial murders. The scope of the problem of serial murders perpetrated by minors is controversial because it often depends on how the number of real cases is counted. Although official statistics indicate the low prevalence of juvenile serial killers, childhood is a period in which antisocial behaviour can have its beginning. Some authors consider that it is not uncommon for the first murder of this type to occur in adolescence. It is important to consider psychopathy as an influential factor in the various forms of serial criminal conduct committed by children and young people. The research works consulted provide evidence of the special relevance of psychopathy in the generation of serious juvenile delinquency.

Bad Is Stronger Than Good

Abstract. Organizational scholars increasingly realize the importance of a dark personality in the workplace. Although a great deal has been learned in terms of the utility of dark personality for the prediction of workplace outcomes, the field has yet to consolidate in terms of which models and measures best reflect the nature of dark personality traits. To facilitate this discussion, the present review examines and evaluates both established and emergent models and measures of dark personality. Further, to inform future research, it also summarizes evidence concerning methodological issues that have been shown to impact levels of dark traits or to moderate their relationships with work outcomes. Finally, the paper considers the implications of widespread practices in the field of dark personality and makes recommendations for future theorizing, research practices, and implementation.

Differential Item Functioning of the Youth Psychopathic Traits Inventory Across Race/Ethnicity and Gender Among a Sample of Justice-Involved Youth: An Item Response Theory Analysis

Research is yet to examine whether the items of the Youth Psychopathic Traits Inventory (YPI) function equally well across race/ethnicity and gender. The current study applies an item response theory analysis to detect differential item functioning (DIF) of the YPI subscale across White, Black, and Hispanic youth and males and females among a sample of justice-involved youth. Significant DIF was detected for several items between Black youth and White youth and Black youth and Hispanic youth. Few incidences of DIF emerged between White and Hispanic youth and between males and females. The findings suggest that subscales of the YPI provide more information for White and Hispanic youth compared with Black youth. They also suggest that while there was significant DIF in the difficulty of items, the direction of DIF did not substantially favor one group or another. Thus, the findings suggest that the YPI produces comparable estimates of psychopathic traits for females and males and for White and Hispanic youth. However, the results raise concerns about comparing YPI subscale scores between White and Black youth and Hispanic and Black youth. The findings have important implications for the use of the YPI subscales among diverse samples.

Measuring judiciarization of people with mental illnesses

The judiciarization of the psychiatric subject is a two-sided process. It could anti-discriminate people with mental illnesses but, at the same time, it could potentially provoke pathologization of mental illnesses. Current methodologies proposed to measure this important and complicated process for people with mental illnesses do not allow analysis on multiple levels (the macro, meso, and micro). In this article, to fill this gap we propose a methodological strategy that helps to investigate judiciarization of people with mental illnesses on multiple levels at once. This approach is based on critical discourse analysis of legal documents and court decisions that feature people with the poor mental health. Namely, we suggest how to measure the level or degree of judiciarization, its geographical evenness, actors in the legal process, its dimensions (the law branches of its occurrence), and linguistic content. We applied this methodology in examining 1,243 legal documents and 327,311 court decisions that were issued by agents of the Russian law system. The research findings show that judiciarization levels in Russia have been rising over the years, moving away from stigmatizing those with mental illnesses and towards anti-discrimination. Our paper could be of interest to socio-legal researchers and social policy practitioners.

The Differentiation of Narrative Styles in Individuals with High Psychopathic Deviate

The current study was designed to show the differentiation of narrative styles in individuals with high scores in Psychopathic deviate (Pd) scale and develop a method enabling identification of psychopathic personality traits based on linguistic indicators. 600 spontaneous narrations related to emotional topics have been examined for grammar, syntactic, and lexical indicators. The indicators have been selected based on a review related to language of psychopaths. The narrations were written by 200 persons who were also tested for psychopathic deviate and intelligence level, including prisoners diagnosed with antisocial personality disorder. Independent judges identified the linguistic indicators which were then counted for each person with the use of computer software. The configuration profiles of the linguistic indicators/narrative styles were established using k-mean clustering method. Then, ANOVA was performed to show which clusters differentiate the levels of psychopathic deviate. The findings show there are two configurations of language features (important: single features were not examined) associated with high levels of psychopathic deviate patterns. Two narrative styles were identified, labelled demonstrative-digressive-egocentric-emotional-dogmatic and reserved-focused on the topic-repetitive, which indicate high psychopathic deviate traits. The ROC curves were applied to establish the prediction of the narrative styles for high psychopathic deviate scores.

Selfish risk-seeking can provide an evolutionary advantage in a conditional public goods game

While cooperation and risk aversion are considered to be evolutionarily advantageous in many circumstances, and selfish or risky behaviour can bring negative consequences for individuals and the community at large, selfish and risk-seeking behaviour is still often observed in human societies. In this paper we consider whether there are environmental and social conditions that favour selfish risk-seeking individuals within a community and whether tolerating such individuals may provide benefits to the community itself in some circumstances. We built an agent-based model including two types of agent-selfish risk-seeking and generous risk-averse-that harvest resources from the environment and share them (or not) with their community. We found that selfish risk-seekers can outperform generous risk-averse agents in conditions where their survival is moderately challenged, supporting the theory that selfish and risk-seeking traits combined are not dysfunctional but rather can be evolutionarily advantageous for agents. The benefit for communities is less clear, but when generous agents are unconditionally cooperative communities with a greater proportion of selfish risk-seeking agents grow to a larger population size suggesting some advantage to the community overall.

Psychopathic Traits, Academic Fraud, and the Mediating Role of Motivation, Opportunity, Rationalization and Perceived Capability

Abstract. This study provides initial insights on the relation between psychopathic traits (disinhibition, meanness, and boldness) and academic fraud (prevalence and severity), while considering important mediators of fraud (perceived capability, opportunity, motivation, and rationalization). Based on a large sample of university students ( N = 967), two structural equation models (test and replication) were built to test the study’s main hypothesis and probe the robustness of the results. A direct link from disinhibition to prevalence was found, suggesting that disinhibition is associated with social deviance in the academic context. Higher motivation for cheating exclusively mediated this path. In meanness, rationalization explained lower rates of perceived severity of academic fraud, indicating that cognitive self-justifications trigger dishonest behavior in meanness. Boldness explained the prevalence of academic fraud via perceived capability, suggesting that low-fear, although adaptive in evaluation contexts, may increase the perceived capability for cheating. The reported significant associations support that academic fraud is part of the nomological network of psychopathy and unveil the complexity of the phenomenon.

Dark Triad but a bright future? Socially malevolent personality traits and proactive career behavior

We explored the effect of the toxic characteristics of the Dark Triad of personality traits, comprising narcissism, Machiavellianism, and psychopathy, on proactive career behavior, and the role of career adaptability as a mediator. We used two-wave lagged data from a survey conducted with 449 Master of Business Administration university students in China. Machiavellianism and narcissism were both positively related to proactive career behavior and career adaptability, but psychopathy was not positively related to either. Further, the effects of Machiavellianism and narcissism on proactive career behavior were mediated by career adaptability. Our results show that narcissism and Machiavellianism play a positive role in explaining important career-related behavior. Theoretical implications and directions for future research are discussed.

Evaluating the validity of brief prototype-based informant ratings of triarchic psychopathy traits in prisoners

The validity of self-report psychopathy assessment has been questioned, especially in forensic settings where clinical evaluations influence critical decision-making (e.g., institutional placement, parole eligibility). Informant-based assessment offers a potentially valuable supplement to self-report but is challenging to acquire in under-resourced forensic contexts. The current study evaluated, within an incarcerated sample (n = 322), the extent to which brief prototype-based informant ratings of psychopathic traits as described by the triarchic model (boldness, meanness, disinhibition; Patrick et al., 2009) converge with self-report trait scores and show incremental validity in predicting criterion measures. Self/informant convergence was robust for traits of boldness and disinhibition, but weaker for meanness. Informant-rated traits showed incremental predictive validity over self-report traits, both within and across assessment domains. These findings indicate that simple prototype-based informant ratings of the triarchic traits can provide a useful supplement to self-report in assessing psychopathy within forensic-clinical settings.
