Personality, the Dark Triad and violence

The Dual Pathways Hypothesis of Incel Harm: A Model of Harmful Attitudes and Beliefs Among Involuntary Celibates

Incels (involuntary celibates) are an online subculture of men who form their identity around a perceived inability to form sexual or romantic relationships. This community operates almost exclusively online, often serving as an outlet for misogynistic hostility. Concerns about violence from incels have positioned them as a growing (inter)national security threat. This study, the largest primary investigation of incel harmful attitudes and beliefs to date (N = 561), recruited participants from the USA and the UK with a mean age of 26 years. Consistent with previous research, the sample showed ethnic and political diversity, poor mental health, high levels of suicidal ideation, and autistic traits. Using a 3N (needs, networks, and narratives) informed theoretical framework, our pathway analysis revealed that poor mental health and ideological adherence were twice as predictive of harmful attitudes and beliefs (e.g., displaced aggression, hostile sexism, and justification of violence) compared to networking, with a bidirectional effect between poor mental health and ideology. We also found two distinct indirect pathways to harmful attitudes and beliefs among incels: one involving experiential vulnerabilities (e.g., autism traits, low mate value, and histories of bullying and abuse) and the other rooted in dispositional traits (e.g., the dark triad and right-wing political orientation), leading us to propose the dual pathways hypothesis of incel harm. These findings suggest that interventions targeting mental health and ideology may be more effective than those focusing solely on online networking. Implications for intervention strategies, informed by these theoretical models, are discussed, including date coaching, therapy and role modeling from former incels. As issues of extremism, online radicalization, and mental health grow in importance, these insights are vital for policymakers, educators, journalists, and others addressing the challenges incels face and represent in society.

Impact of Dark Triad personality traits on COVID-19 vaccination uptake and prevention efforts: insights from the European Covid Survey (ECOS)

BACKGROUND

Even though the COVID-19 vaccination roll-out in general can be considered as one of the most successful public health campaigns in the history of medicine, general vaccination hesitancy has remained an issue of concern throughout the world. We add to a deeper understanding of vaccination hesitancy by identifying what drives primary vaccination and booster uptake, as well as adherence to simple preventive measures such as physical distancing by investigating the role of Dark Triad personality traits, i.e. Machiavellianism, narcissism, and psychopathy.

METHODS

We investigate data from Germany and the United Kingdom from the European Covid Survey which was collected from 23 December 2021 to 10 January 2022. Logit regressions and random effects regressions were performed to study the effect of dark personality traits on COVID-19-related prevention.

RESULTS

We find a statistically significant association between Dark Triad personality traits and prevention efforts, primary vaccinations, and booster uptake against COVID-19. Specifically, individuals scoring high in psychopathy are associated with a lower likelihood of having received primary immunization. The marginal effect amounts to 3.31%-points. High narcissistic personality traits are correlated with a substantially higher likelihood (4.52%-points) to refuse booster shots after having received the primary vaccinations. Dark Triad personality traits may be relevant factors associated with vaccine-related decision-making. In addition, individuals with higher psychopathic tendencies report significantly lower engagement in other simple preventive behavior, while higher scores in narcissism are associated with higher reported adherence to simple preventive measures.

CONCLUSIONS

Our findings highlight the crucial role that personality plays in pandemic-related prevention. Policymakers, health professionals, and those in charge of health messaging may take these factors into account when devising communication strategies to improve the vaccination uptake and adherence to preventive behaviors. Future pandemics and public health crises would benefit from targeted, nuanced approaches to public health messaging to promote greater public adherence and public health.

The role of worldviews, radicalization risk factors, and personality in harassment of scientists

Anti-science movements brought more than public distrust in science. Perhaps even more worryingly, these movements are also associated with instances of harassment of-and violence against-scientists. However, virtually nothing is known about individuals likely to harass or harm scientists. Across two pre-registered studies (total N = 749), we investigated the role of worldviews (e.g., political ideology, conspiracy mentality, science cynicism), radicalization risk factors (relative deprivation and threat), and personality traits and how these relate to harassment of scientists (both attitudes and behavior). We found that science cynicism-the perception that scientists are incompetent and corrupt-drives approval of scientists' harassment (attitudes), as well as harmful behavior (e.g., refusing to donate money, not signing a petition). Additionally, perceiving scientists as threatening, as well as dark personality traits (psychopathy and narcissism), contributed to approving scientists' harassment. Overall, the present research takes a first step in identifying predictors of the willingness to harm scientists.

Machiavellianism and Intimate Partner Violence Perpetration: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis estimated the size of the relationship between Machiavellianism and intimate partner violence (IPV) perpetration. Further, we explored whether the strength of this relationship varied depending on IPV type (i.e., physical, psychological, sexual, and cyber), and perpetrator gender. Systematic searches of Medline Complete, PsycInfo, Scopus, and Web of Science databases were conducted on July 4, 2023. Studies were included if they were a peer-reviewed published paper or unpublished dissertation, in English, included a measure of Machiavellianism and IPV perpetration, and reported the relationship between these variables. Study quality was assessed using the AXIS tool. Nineteen studies (N = 9,464) were included in a random-effects meta-analysis revealing a significant, weak, positive correlation between Machiavellianism and IPV perpetration (r = .16, 95% CI [0.11, 0.21], p < .001). Machiavellianism had a significant, weak, positive relationship with cyber (r = .25, 95% CI [0.17, 0.32], p < .001), psychological (r = .20, 95% CI [0.15, 0.24], p < .001), and sexual IPV (r = .10, 95% CI [0.02, 0.19], p = .020). No significant relationship was found for physical IPV. There was no significant difference in the strength of the relationship between women and men. These findings are limited by the measures being self-report, heterogeneity across studies, and the cross-sectional nature of the included studies which limits the understanding of causal pathways. Nonetheless, this meta-analysis shows a link between Machiavellianism and IPV perpetration, and future research should examine how this knowledge may be used to reduce IPV perpetration.

Dark triad personality traits are associated with decreased grey matter volumes in 'social brain' structures

Introduction

Personality traits and the degree of their prominence determine various aspects of social interactions. Some of the most socially relevant traits constitute the Dark Triad - narcissism, psychopathy, and Machiavellianism - associated with antisocial behaviour, disregard for moral norms, and a tendency to manipulation. Sufficient data point at the existence of Dark Triad 'profiles' distinguished by trait prominence. Currently, neuroimaging studies have mainly concentrated on the neuroanatomy of individual dark traits, while the Dark Triad profile structure has been mostly overlooked.

Methods

We performed a clustering analysis of the Dirty Dozen Dark Triad questionnaire scores of 129 healthy subjects using the k-means method. The variance ratio criterion (VRC) was used to determine the optimal number of clusters for the current data. The two-sample t-test within the framework of voxel-based morphometry (VBM) was performed to test the hypothesised differences in grey matter volume (GMV) for the obtained groups.

Results

Clustering analysis revealed 2 groups of subjects, both with low-to-mid and mid-to-high levels of Dark Triad traits prominence. A further VBM analysis of these groups showed that a higher level of Dark Triad traits may manifest itself in decreased grey matter volumes in the areas related to emotional regulation (the dorsolateral prefrontal cortex, the cingulate cortex), as well as those included in the reward system (the ventral striatum, the orbitofrontal cortex).

Discussion

The obtained results shed light on the neurobiological basis underlying social interactions associated with the Dark Triad and its profiles.

Parental burnout and borderline personality stand out to predict child maltreatment

Parental burnout is a severe disorder resulting from the exposure to chronic stress in the parental role, that can translate into neglectful and violent parental behaviors towards the offspring. This study (N = 1003 parents) aims to examine the relative weight of parental burnout, job burnout, depression, generalized anxiety disorder, borderline personality, sadism, psychopathy, Machiavellianism, narcissism, and child abuse potential, in predicting violence and neglect towards the offspring. Social desirability was controlled. When all predictors are entered together in the model, violence and neglect towards the offspring are best predicted by borderline personality and parental burnout. Our results also indicate that sadism is a robust predictor of violence, however weaker than parental burnout and borderline personality. These results emphasize the importance of preventing parental burnout and supporting parents with borderline personality.

How Anti-Social Personality Traits and Anti-Establishment Views Promote Beliefs in Election Fraud, QAnon, and COVID-19 Conspiracy Theories and Misinformation

Conspiracy theories and misinformation (CTM) became a salient feature of the Trump era. However, traditional explanations of political attitudes and behaviors inadequately account for beliefs in CTM or the deleterious behaviors they are associated with. Here, we integrate disparate literatures to explain beliefs in CTM regarding COVID-19, QAnon, and voter fraud. We aim to provide a more holistic accounting, and to determine which political, psychological, and social factors are most associated with such beliefs. Using a unique national survey, we find that anti-social personality traits, anti-establishment orientations, and support for Donald Trump are more strongly related to beliefs in CTM than traditional left-right orientations or other frequently posited factors, such as education, science literacy, and social media use. Our findings encourage researchers to move beyond the traditional correlates of political behavior when examining beliefs that express anti-social tendencies or a deep skepticism of social and political institutions.

Personality Traits as Predictors of Malevolent Creative Ideation in Offenders

Malevolent creativity, which can be defined as creativity that is deliberately planned to damage others, is a concept that explains how the capacity to generate novel and effective outcomes (creativity) may, on occasion, be misapplied. The present study used 130 male inmates of the Oradea Maximum Security Penitentiary in Romania to explore the ability of a set of personality variables (the dark triad, self-efficacy, and self-esteem) to predict malevolent creative ideation. The findings indicate that Machiavellianism and self-efficacy were significant predictors of malevolent creative ideation in the form of lying, while only Machiavellianism was a significant predictor of malevolent creative ideation in the form of hurting people. In addition, the present study found significant differences among subgroups in the sample, with more experienced offenders showing higher levels of malevolent creative ideation.

Falsification of the Sexual Experiences Questionnaire: No Evidence of Systemic Sexual Harassment in Academic STEM

Herein, the socio-psychological narrative of sexual harassment (SH) is critically evaluated. The notion of systemic SH in university departments of science, technology, engineering, and mathematics (STEM) is contradicted by the overwhelming (>90%) career satisfaction among female STEM academics. The Sexual Experiences Questionnaire (SEQ), central to the study of SH, inheres the nominalistic fallacy. SEQ usage deploys subjectivist methodologies, categorical ambiguity, the post hoc ergo propter hoc fallacy, and treats respondents as cyphers. Intercorrelation of SEQ factors reduces response statistics by 42%, while phase-space vector geometry indicates the SEQ does not measure SH. Personality analysis implies that serial abusers dominate the incidence of SH. The widespread notion that 20–25% of female college students suffer violent sexual assault rests on a misreading of published work. The 2016 Campus Climate Survey permits an upper limit estimate that 3.2% of female college students suffer rape at the hands of 4.3% of male student perpetrators, largely accompanied by drugs or alcohol. The 2018 National Academy (NAS) Report on sexual harassment in STEM exhibits negligent scholarship and carelessly generalizing statistics and may itself promote violation of the EEOC legal definition of SH. Despite instances of grievous sex-based abuse, there is no evidence that female STEM academics face systemic sexual harassment. Finally, evolutionary psychology and the social significance of personality provide a scientific understanding of SH.

Dark Triad Psychopathy Outperforms Self-Control in Predicting Antisocial Outcomes: A Structural Equation Modeling Approach

Dark Triad traits and self-control are considered viable causal precursors to antisocial and criminal outcomes in youth. The purpose of the present study is to concurrently compare how Dark Triad traits and self-control differ in terms of predicting self-reported juvenile delinquency, CD symptoms, proactive overt aggression, and crime seriousness. The sample consisted of 567 (M = 15.91 years, SD = 0.99 years, age range = 14–18 years) Southern European youth from Portugal. Structural-equation-modelling procedures revealed that the psychopathy factor of Dark Triad traits presented the strongest significant hypothetical causal associations with the antisocial/criminal outcomes, followed by self-control. Machiavellianism and narcissism presented the lowest causal associations. Our findings indicate that psychopathy, as operationalized in the Dark Triad, concurrently surpasses self-control and the remaining factors of the Dark Triad in terms of predicting antisocial/criminal outcomes in youth. This suggests that behavioral disinhibition, or a core incapacity to regulate one’s conduct, is central for understanding delinquency and externalizing psychopathology. Comparatively, the interpersonal component of dark personality features, such as Machiavellianism and narcissism, are secondary for understanding crime.

Evading Detection: What Do We Know about Men Charged with Extrafamilial Child Sexual Abuse following Delayed Detection?

Most child sexual abuse (CSA) remains unreported and undetected. Despite this, much of what we know about perpetrators of CSA is derived from samples of convicted CSA offenders. Significant knowledge gaps remain about those who have evaded detection. This study addresses this gap with an in-depth content analysis of the case files of ten convicted child sexual offenders (CSOs) with the longest detection lag, selected from a broader group (n = 349) of men incarcerated at the Massachusetts Treatment Center (MTC). Participants were examined on a range of offender characteristics including Adverse Childhood Experiences (ACEs), cognitive distortions, antisocial traits, indicators of pedophilia and Machiavellian or narcissistic traits, offense facilitating factors, and grooming behavior. A tentative profile emerged with the following characteristics: direct experience of childhood abuse, various cognitive distortions, specialized rather than versatile criminal history, pedophilic traits, Machiavellian traits, and engaging in a range of offense-facilitating behaviors including grooming. We provide insight into offenders who evade detection for CSA and set the foundation for further research to inform prevention strategies for law enforcement agencies and child-serving organizations.

Testing Measurement Invariance of the Dark Triad Dirty Dozen in a Belgian Adult Sample

The Dirty Dozen (Jonason & Webster, 2010) is a frequently used concise version of the Dark Triad to measure three socially aversive personality traits: Machiavellianism, psychopathy and, narcissism. The present study has examined measurement invariance in a sample of Belgian adults. The present study aims to assess measurement invariance of the Dutch version of the Dirty Dozen measure across gender in a large city-based representative adult sample in Belgium (N = 1587). Multi-group first-order confirmatory factor analysis for categorical indicators was utilized. In addition, unique associations between Dirty Dozen traits, trait self-control and, acceptance of illegitimate norms were examined in a series of structural equation models. Results indicated that the internal consistency of the Dirty Dozen subscales was good for Machiavellianism (α = 0.80) and narcissism (α = 0.80), but modest for psychopathy (α = 0.64). The hypothesized three correlated factors model with separate factors for Machiavellianism, psychopathy and, narcissism provided a poor fit for men and women. Invariance testing across gender showed evidence for weak invariance only, indicating that the underlying latent factors are measured the same way with the same metric in the two populations. However, we were not able to establish strong measurement invariance. Observed group differences should be interpreted with caution. Furthermore, Machiavellianism and psychopathy were strongly associated with trait self-control in both men and women. Strong correlations were found between acceptance of illegitimate norms and Dirty Dozen traits, Machiavellianism and, psychopathy, but not with narcissism.

The Facilitative Effect of Impulsiveness on The Dark Triad and Social Network Sites Addiction

This research investigated the relationships of the Dark Triad, impulsiveness, and social network sites (SNS) addiction with adolescents. In particular, this research examined the indirect effects of the measured motor, attentional, and nonplanning impulsiveness on the relationship of the Dark Triad and SNS addiction. To examine the possible antecedents of SNS addiction, 169 adolescents aged 14-17 were recruited for this research. After obtaining informed consents from their legal guardians, these adolescents completed the Dirty Dozen, the modified Bergen Facebook Addiction Scale, and the Barratt Impulsiveness Scale – version 11. Results showed that the Dark Triad composite score was positively correlated with SNS addiction and the different aspects of impulsiveness, while SNS addiction was positively correlated with motor impulsiveness. The indirect effect of motor impulsiveness on the relationship of the Dark Triad and SNS addiction was significant. The present findings provide theoretical insights to the development of SNS addiction.

Dark triads, tetrads, tents, and cores: Why navigate (research) the jungle of dark personality models without a compass (criterion)?

This comprehensive review summarizes and evaluates the present state of the Dark Triad research literature (or more broadly, the dark personality trait literature), and as such serves both a pedagogical purpose, by providing an introduction or primer on the dark personality literature and a scientific purpose by directing future research on key issues that still have not been sufficiently addressed. In this review, we discuss and critique current operational conceptualizations of what it means for a personality trait to be classified as 'dark'. Also discussed is the Dark Core, as well as quantitative issues such as limitations of commonly used statistical treatments, such as multivariate analyses, bifactor modeling, and composite measures, and proposed solutions to some of these issues. Based on a comprehensive and critical appraisal of the literature, future directions are suggested to drive the dark trait field towards a more organized, parsimonious, and productive future.

Measuring the Dark Core of Personality in German: Psychometric Properties, Measurement Invariance, Predictive Validity, and Self-Other Agreement

The Dark Factor of Personality (D)-the underlying disposition of aversive traits-has been shown to account for various ethically and socially aversive behaviors. Whereas previous findings support the reliability and validity of the original English item sets suggested to measure D, a thorough psychometric examination of their German translation is still pending. Using data from four different samples (total N > 33,000), this study comprehensively evaluates the German version of the D70, D35, and D16 with respect to (a) their factor structure, (b) measurement invariance across gender, (c) measurement equivalence with the original English item sets, (d) predictive validity for relevant outcomes across a six-month period, and (e) self-observer agreement. Results confirm the bifactor structure of the D70 and single-factor models for the D35 and the D16. Measurement invariance testing shows partial strict invariance across gender and language versions. Furthermore, predictive validity and a moderate degree of self-other agreement are supported. The German version of the D70 and its shorter versions thus allow for a psychometrically sound assessment of D.

Does Machiavellianism meaningfully differ from psychopathy? It depends

Machiavellianism is a personality construct characterized by cynicism, callousness, and skillful manipulation of others to achieve personal gains. We review the Machiavellianism literature with a particular focus on its measurement alongside narcissism and psychopathy in the so-called "Dark Triad" (DT). We discuss criticisms of Machiavellianism on the grounds of insufficient construct validity as well as its virtual indistinguishability from psychopathy when assessed by commonly used instruments. As a response to these criticisms, we offer the super-short form of the Five Factor Machiavellianism Inventory (FFMI-SSF) as an alternative. The goal of the present study was to evaluate the FFMI-SSF in relation to psychopathy and basic personality traits (i.e., the Five Factor Model) and to compare it to widely used measures of the DT and psychopathy in a large undergraduate sample (n = 1004).

A Common CDH13 Variant Is Associated with Low Agreeableness and Neural Responses to Working Memory Tasks in ADHD

The cell—cell signaling gene CDH13 is associated with a wide spectrum of neuropsychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), autism, and major depression. CDH13 regulates axonal outgrowth and synapse formation, substantiating its relevance for neurodevelopmental processes. Several studies support the influence of CDH13 on personality traits, behavior, and executive functions. However, evidence for functional effects of common gene variation in the CDH13 gene in humans is sparse. Therefore, we tested for association of a functional intronic CDH13 SNP rs2199430 with ADHD in a sample of 998 adult patients and 884 healthy controls. The Big Five personality traits were assessed by the NEO-PI-R questionnaire. Assuming that altered neural correlates of working memory and cognitive response inhibition show genotype-dependent alterations, task performance and electroencephalographic event-related potentials were measured by n-back and continuous performance (Go/NoGo) tasks. The rs2199430 genotype was not associated with adult ADHD on the categorical diagnosis level. However, rs2199430 was significantly associated with agreeableness, with minor G allele homozygotes scoring lower than A allele carriers. Whereas task performance was not affected by genotype, a significant heterosis effect limited to the ADHD group was identified for the n-back task. Heterozygotes (AG) exhibited significantly higher N200 amplitudes during both the 1-back and 2-back condition in the central electrode position Cz. Consequently, the common genetic variation of CDH13 is associated with personality traits and impacts neural processing during working memory tasks. Thus, CDH13 might contribute to symptomatic core dysfunctions of social and cognitive impairment in ADHD.

The Khoekhoegowab Personality Inventory: The Comparative Validity of a Locally Derived Measure of Traits

Objective: This study explores a personality inventory derived from the results of an indigenous lexical study of personality. From the 272 most commonly used personality descriptors in Khoekhoegowab, the most-spoken of extant Khoesan click languages of southern Africa, an 11-factor model of personality-trait structure was identified. Here, the Khoekhoegowab Personality Inventory (KPI) was created based on those results. Its psychometric properties, the convergent and divergent validity of its scales, and its incremental validity over Big Five and Six traits for predicting physical and mental health, religious practice and attitudes, and income are reported. Methods: Two to five key terms were selected for each of 10 KPI scales: Temperance, Prosocial Diligence, Gossip, Honesty/Morality, Temper, Implacability, Humility, Vanity, Resiliency vs. Agitation, and Courage vs. Fear. These 38 total items were administered to a large sample of adult speakers of Khoekhoegowab in Namibia (N = 632), together with five imported inventories translated into Khoekhoegowab: the 30-item Questionnaire Big Six (QB6), General Self-Reported Health, the Cascades Mental Health Assessment, the Satisfaction with Life Scale, the Duke Religion Index. The properties and intercorrelations of KPI subscales are explored, and their predictive ability for the other variables is compared to that of the QB6. Results: Due to the small number of items on each scale, poor internal consistency was anticipated, but the KPI scales' properties were somewhat better than those of the QB6. R-square change by the inventories as a whole, after accounting for age and gender, indicted that the KPI scales explained more variance than the QB6 scales in almost all criterion variables. Replication of established associations for Big Six traits was mixed: associations were largely as expected for Resiliency, Conscientiousness, and Honesty, but less so for Agreeableness and Extraversion. Conclusions: The KPI had some advantages over the QB6 in predicting physical and mental health. In particular, the four items of Resiliency vs. Agitation predicted lower scores on all physical and mental problem scales. Given psychological-care needs in Namibia, this might be used as a non-intrusive screener. Measurement challenges common to both surveys are discussed, possible solutions, and the utility of higher-order structures are discussed.

The Dark Triad of Personality's Relationship with Compliance towards COVID-19 Pandemic Recommendations along with Anxiety and Depressive Symptoms in Polish Citizens

The outbreak of the COVID-19 pandemic forced everyone to comply with rules of a sanitary regime and social distancing on a daily basis. The aim of our research was to assess the differences in the levels of Dark Triad traits between people who obeyed and disobeyed the pandemic restrictions. Additionally, we considered the possible correlation between the Dark Triad and the intensity of symptoms of depression and anxiety. A total of 604 Polish participants, whose average age was 28.95 ± 11.27 years, completed an online survey which measured Dark Triad traits using the Polish version of the Dirty Dozen test. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). The results revealed a possible relationship between personality traits and compliance with pandemic restrictions. Individuals with higher levels of psychopathy tended to disobey newly introduced rules. On the other hand, a higher level of subclinical narcissism might have contributed to a better civil compliance. The results showed a significant positive correlation between the intensity of the Dark Triad and the occurrence of depressive symptoms. Furthermore, narcissism was linked to anxiety symptoms. These results can contribute to a better understanding of behavioural patterns during the COVID-19 pandemic within the group of individuals who exhibit the Dark Triad traits. Our conclusions might help to identify individuals who are particularly vulnerable to mental health problems.

Our Vulnerable Dark Side-Two Laboratory Approaches

The Dark Triad of personality has been associated with aggression against others as a reaction to perceived provocations. However, previous work has also shown that such responsive aggression even occurs if it means harming oneself. The first of two laboratory studies aimed to investigate whether this relation between the Dark Triad and self-harming behavior also occurs in situations where no others are affected but self-harm is likely. The second laboratory study considered two different settings in a within-participants design in order to analyze the stability of self-harming behavior and to what extent the Dark Triad constructs influence this behavior. The sample for study 1 consisted of 151 students (45.7% female) with a mean age of 21.40 years (SD = 2.19); the sample for study 2 consisted of 251 students (76.0% female) with a mean age of 22.21 years (SD = 3.90). Aside from the Dark Triad's common core, depending on how self-harm was triggered (ego-threat (mainly narcissism), being alone with one's own thoughts (mainly psychopathy), or reward condition (mainly Machiavellianism)), the Dark Triad traits differed in their responsiveness but were stable over the last two conditions, thereby suggesting a vulnerable side of the Dark Triad.

The Dark Side of Human Values: How Values are Related to Bright and Dark Personality Traits

In the present research, we replicate and extend previous findings on the relations between human values and bright\dark traits of personality, using the functional theory of human values (Gouveia, 2013). Specifically, we assessed which dark traits are associated with human values and whether the dark traits explained variance in values beyond the bright traits (Big Five). While prior research has investigated the relations between the three sets of constructs mainly in Western countries, we tested whether the findings hold in Brazil (N = 819). Although values are defined as positive constructs, several value subfunctions were positively correlated with the dark traits (e.g., excitement values with narcissism), while other relations were negative. Controlling for participants' age and gender, hierarchical regressions further revealed that dark traits explain variance in values beyond bright traits, although overall bright traits were more strongly associated with values than dark traits. Together, our findings replicate previous research. Implications for our understanding of the Dark Triad and cross-cultural research are discussed.

Mentalization for Offending Adult Males (MOAM): study protocol for a randomized controlled trial to evaluate mentalization-based treatment for antisocial personality disorder in male offenders on community probation

BACKGROUND

Antisocial personality disorder (ASPD), although associated with very significant health and social burden, is an under-researched mental disorder for which clinically effective and cost-effective treatment methods are urgently needed. No intervention has been established for prevention or as the treatment of choice for this disorder. Mentalization-based treatment (MBT) is a psychotherapeutic treatment that has shown some promising preliminary results for reducing personality disorder symptomatology by specifically targeting the ability to recognize and understand the mental states of oneself and others, an ability that is compromised in people with ASPD. This paper describes the protocol of a multi-site RCT designed to test the effectiveness and cost-effectiveness of MBT for reducing aggression and alleviating the wider symptoms of ASPD in male offenders subject to probation supervision who fulfil diagnostic criteria for ASPD.

METHODS

Three hundred and two participants recruited from a pool of offenders subject to statutory supervision by the National Probation Service at 13 sites across the UK will be randomized on a 1:1 basis to 12 months of probation plus MBT or standard probation as usual, with follow-up to 24 months post-randomization. The primary outcome is frequency of aggressive antisocial behaviour as assessed by the Overt Aggression Scale - Modified. Secondary outcomes include violence, offending rates, alcohol use, drug use, mental health status, quality of life, and total service use costs. Data will be gathered from police and criminal justice databases, NHS record linkage, and interviews and self-report measures administered to participants. Primary analysis will be on an intent-to-treat basis; per-protocol analysis will be undertaken as secondary analysis. The primary outcome will be analysed using hierarchical mixed-effects linear regression. Secondary outcomes will be analysed using mixed-effects linear regression, mixed-effects logistic regression, and mixed-effects Poisson models for secondary outcomes depending on whether the outcome is continuous, binary, or count data. A cost-effectiveness and cost-utility analysis will be undertaken.

DISCUSSION

This definitive, national, multi-site trial is of sufficient size to evaluate MBT to inform policymakers, service commissioners, clinicians, and service users about its potential to treat offenders with ASPD and the likely impact on the population at risk.

Dark personality traits and cyber aggression in adolescents: A moderated mediation analysis of belief in virtuous humanity and self-control

Cyber aggressive behavior among adolescents is a widespread concern. However, little is known about the influencing factors and psychological mechanism of cyber aggressive behavior in adolescents. This study examined whether dark personality traits would be associated with cyber aggression in adolescents, whether belief in virtuous humanity would mediate the relationship between dark personality traits and cyber aggression, and whether self-control would play a moderating role in the links. A total of 675 Chinese college students completed a series of anonymous questionnaires regarding dark personality traits, belief in virtuous humanity, self-control, and cyber aggression. Results showed the following: (1) dark personality was positively related to cyber aggression in adolescents; (2) belief in virtuous humanity mediated the relationship between dark personality traits (i.e., Machiavellianism and psychopathy) and cyber aggression; (3) self-control play a moderating role in the relationship between dark personality traits (i.e., Machiavellianism and psychopathy) and cyber aggression, and the relationship between belief in virtuous humanity and cyber aggression. This study could help demonstrate the risk and protective factors and psychological mechanism of cyber aggressive behavior in adolescents. Some theoretical and practical implications and limitations were also discussed.

Der Generalfaktor der Persönlichkeit und die Dunkle Triade

Zusammenfassung. Um die komplexe Verbindung zwischen Wesenskennzeichen und Führungserfolg auf Top-Managementebene zu entschlüsseln, bietet der Generalfaktor der Persönlichkeit (GFP) eine interessante, aber bis dato eher selten genutzte Alternative zu herkömmlichen Konzepten der Persönlichkeitspsychologie. Hier setzt die vorliegende Studie an. Sie extrahiert aus den klassischen Dimensionen der Big Five einen übergeordneten Generalfaktor und verknüpft diesen mit den Persönlichkeitsmerkmalen der Dunklen Triade. Die Erhebung bei 320 deutschen Vorständen und Geschäftsführern zeigt, dass sich der Persönlichkeitsfaktor speziell für das Top-Management (GFP-E) durch die Faktorladungen und hinsichtlich der Facettenhierarchie vom herkömmlichen GFP unterscheidet. Der spezifisch für Executives ermittelte GFP-E korreliert positiv mit individuellen Erfolgs- und Zufriedenheitsmaßen sowie mit Narzissmus, einer Dimension der Dunklen Triade. Außerdem zeigen sich negative Zusammenhänge zu Machiavellismus und Psychopathie. Die Ergebnisse erlauben weiterführende Implikationen für die Forschung sowie die Auswahl und Förderung von Managern in der Unternehmenspraxis.

The Light vs. Dark Triad of Personality: Contrasting Two Very Different Profiles of Human Nature

While there is a growing literature on "dark traits" (i.e., socially aversive traits), there has been a lack of integration with the burgeoning research literature on positive traits and fulfilling and growth-oriented outcomes in life. To help move the field toward greater integration, we contrasted the nomological network of the Dark Triad (a well-studied cluster of socially aversive traits) with the nomological network of the Light Triad, measured by the 12-item Light Triad Scale (LTS). The LTS is a first draft measure of a loving and beneficent orientation toward others ("everyday saints") that consists of three facets: Kantianism (treating people as ends unto themselves), Humanism (valuing the dignity and worth of each individual), and Faith in Humanity (believing in the fundamental goodness of humans). Across four demographically diverse samples (N = 1,518), the LTS demonstrated excellent reliability and validity, predicting life satisfaction and a wide range of growth-oriented and self-transcendent outcomes above and beyond existing measures of personality. In contrast, the Dark Triad was negatively associated with life satisfaction and growth-oriented outcomes, and showed stronger linkages to selfish, exploitative, aggressive, and socially aversive outcomes. This exploratory study of the contrasting nomological networks of the Light vs. Dark Triad provides several ways forward for more principled and data driven approaches to explore both the malevolent and beneficent sides of human nature.

The social anatomy of adverse childhood experiences and aggression in a representative sample of young adults in the U.S

Objective The current study assesses the effect of adverse childhood experiences on later aggression and violence across young adult relationships contexts, including intimate partners, friends, or strangers. Method Surveys were conducted with a nationally representative sample of young adults ages 18-32, drawn from the AmeriSpeak panel, a probability-based panel with coverage of 97% of U.S. households. The weighted study sample is 2284 young adult respondents, of whom 1561 reported being in an intimate partnership. Results Rates of verbal aggression perpetrated by young adults declined with the intimacy of the relationship, such that aggression against a partner (72%) exceeded aggression directed at friends (43%) and strangers (34%). Similar rates of physical violence (about 9%) were reportedly perpetrated against partners, friends, and strangers. Adjusting for a range of personal characteristics, both adverse childhood experiences and recent stressors in these young adult lives exhibited direct associations with verbal and physically aggressive outcomes. Conclusions In models of verbal and physical aggression across relationship contexts, childhood adversity exhibits lasting effects unaccounted for by important proximal life circumstances, including recent life stressors, mental health, and substance use behaviors. These results provide empirical insights for clinical treatment of young adults prone to aggressive conflicts as well as input to positive youth development programming to foster healthy approaches to conflict.

The influence of impulsivity and the Dark Triad on self-reported aggressive driving behaviours

The present study tested the role of Dark Triad traits (DT; narcissism, psychopathy, and Machiavellianism) as potential contributors to self-reported aggressive driving alongside driving anger, general aggression, impulsiveness, and attributions of malign driving intent. Members of the general community (N = 168) completed an online survey battery measuring these characteristics, and a proxy measure of aggressive driving. Regression analyses revealed that psychopathy, a history of physical aggression towards others, and the "progress impeded" aspect of driving anger, accounted for 50.8% of the variance in self-reported aggressive driving behaviours. The remaining variables were not significant. A structural equation model found all measures fitted into a single model in which impulsivity and the DT predicted general aggression, general aggression fully mediated the effect of the DT on driving anger, and general aggression and progress impedance predicted self-reported aggressive driving (GFI = 0.925). These results indicate tendencies toward expressing aggression physically, frustration at goals being impeded, and a callous, impulsive nature can predispose an individual to aggressive driving behaviours. Implications of these findings and recommendations for research are discussed.

The Dark Triad and framing effects predict selfish behavior in a one-shot Prisoner's Dilemma

What causes us to display selfish behaviors? We explored the extent to which Dark Triad traits (sub-clinical psychopathy, narcissism, and Machiavellianism) support a selfish behavioral strategy. We related performance on a hypothetical Prisoner's Dilemma (an economic game that simulates a two-person social dilemma) to participants' (N = 1400) Dark Triad scores. Because contextual factors also impact selfish behaviors, we tested how framing (gain vs. loss; and social vs. nonsocial) shaped performance in the Prisoner's Dilemma. Participants with high Dark Triad scores were more likely to behave selfishly in the Prisoner's Dilemma. Participants were also most likely to betray their partner in loss-framed and non-socially framed contexts. These effects did not interact with Dark Triad scores. Our data are consistent with the view that seemingly negative personality traits (like those associated with the Dark Triad traits) that persist in the population may serve as evolutionarily adaptive behavioral strategies.

Machiavellianism, Relationship Satisfaction, and Romantic Relationship Quality

Machiavellianism is characterised by a manipulative interpersonal style, willingness to exploit others, and a preference for emotionally detached relationships. The present studies investigate the extent to which Machiavellianism influences relationship satisfaction and romantic relationship quality. In Study 1, 194 heterosexual partnered women completed Machiavellianism and Relationship Satisfaction measures. Women with higher levels of Machiavellianism reported lower levels of relationship satisfaction. In Study 2, 132 heterosexual partnered women completed Machiavellianism, Trust, Commitment, Control, and Emotional Abuse scales. Women with higher levels of Machiavellianism perceived their partners to be less dependable, reported less faith in their partners, and were less willing to persist with the relationship than those with low levels of Machiavellianism. With regards to negative behavior, Machiavellianism predicted each form of control and emotional abuse investigated, such that those with high levels of Machiavellianism were more likely to engage in controlling behavior and emotional abuse. Findings have important implications for the prediction of romantic relationship quality and in particular for negative behavior such as control and abuse.

The Malevolent Side of Human Nature

The term dark triad refers to the constellation of narcissism, Machiavellianism, and psychopathy. Over the past few years, the concept has gained momentum, with many researchers assuming that the dark triad is a prominent antecedent of transgressive and norm-violating behavior. Our purpose in this meta-analytic review was to evaluate (a) interrelations among narcissism, Machiavellianism, and psychopathy; (b) gender differences in these traits; (c) how these traits are linked to normal personality factors; and (d) the psychosocial correlates of the dark triad. Our findings show that dark triad traits are substantially intercorrelated, somewhat more prevalent among men than women, predominantly related to the Big Five personality factor of agreeableness and the HEXACO factor of honesty-humility, and generally associated with various types of negative psychosocial outcomes. We question whether dark triad traits are sufficiently distinct and argue that the way they are currently measured is too simple to capture the malevolent sides of personality. Because most research in this domain is cross-sectional and based on self-reports, we recommend using a cross-informant approach and prospective, longitudinal research designs for studying the predictive value of dark triad features.
