Unfeeling or Uncontrolled? PCL-R Subfactor-Specific Anomalies in Psychological Processing During Criminal Behavior.

Psychopathy has been linked to insensitivity to negative affect as well as to a self-regulatory deficit. However, studies on these associations rarely involve real-life behavioral data. Using a theory-based content analysis of offense descriptions in criminal verdicts, the affective and regulatory processes that male German prison inmates (N = 109) displayed during criminal norm-violations were coded. Their PCL-R scores were split up into the interpersonal-affective (F1) and the lifestyle-antisocial (F2) factors. As expected, F1 was associated with positive (as opposed to negative) activation affect during criminal behavior (τ = .32, p < .001), while F2 was not. In contrast, F2 was associated with impulsive reactivity (τ = .14, p = .03), while F1 was not. No differential association was found with angry emotionality. Overall, the bifactorial nature of the PCL-R psychopathy construct seems to be reflected in psychological processing during real-life criminal behavior. This might indicate differential criminogenic processes.

Redemption or Manipulation? Revisiting the Art of a Serial Killer-A Dialogue.

This article revisits an ongoing dialogue between the co-authors, examining their divergent perspectives on whether the art of serial killers was used to perpetuate their psychopathic cycles after their murderous sprees were interrupted, or whether the art-particularly a piece done by one serial killer, Glen Rogers-reflects remorse and redemption. The two art therapists draw from their own clinical and professional experiences to argue their respective outlooks. After explaining what art therapy is, re-examining the concept of murderabilia, and underscoring psychopathy, this article provides an in-depth evaluation of two art pieces done by the serial killer through both of their viewpoints. Ultimately, while neither author completely changed their overall conclusions, elements from both sides of the argument were found relevant. Ultimately, this article emphasized the chaotic and messy connections between art and violence, yet through new perspectives explored on the complexities and motivations within the mayhem, mutual understandings emerged.

Will the Dark Triad Engender Psychopathological Symptoms or Vice Versa? A Three-Wave Random Intercept Cross-Lagged Panel Analysis.

INTRODUCTION: The Dark Triad (DT), including narcissism, Machiavellianism, and psychopathy, represents the dark side of human nature and has been related to psychopathological symptoms (e.g., depression, anxiety, and stress). However, little is known about how the two constructs are related longitudinally. To fill this gap and to clarify the directionality between them, we conducted a longitudinal study. METHODS: We measured DT traits and psychopathological symptoms in a large sample of university students (NT1 = 1815) annually for 3 years. We implemented random intercept cross-lagged panel models in analysis. RESULTS: Narcissism and psychopathological symptoms showed a reciprocal relationship at the within-person level: greater narcissism preceded a decline in psychopathological symptoms, while more severe symptoms preceded a decrease in narcissism. Within the same individual, increases in the DT, particularly psychopathy and Machiavellianism, were linked to concurrent escalations in the symptoms. Additionally, all DT traits were positively correlated with psychopathological symptoms as stable differences between individuals. CONCLUSIONS: This study constitutes an important step in clarifying the directionality between the DT and psychopathological symptoms, and advances our understanding of the interplay between these two constructs at both the between-person and within-person levels.

The relationship between the Dark Triad and academic burnout mediated by perfectionistic self-presentation.

Individuals with dark personality traits are more prone to burnout, but this was not yet investigated in academia. Perfectionistic self-presentation (PSPS), an interpersonal expression of perfectionism, could be an explaining factor. Therefore, we investigated the relationship between the dark triad (Machiavellianism, vulnerable and grandiose narcissism, and psychopathy) and academic burnout, and whether the PSPS total score and its dimensions (perfectionistic self-promotion, nondisplay of imperfection, and nondisclosure of imperfection) mediates this. We expected that higher dark triad traits would be associated with higher academic burnout and that this would be explained by higher PSPS. Hypotheses included expectations for each PSPS dimension as well. Questionnaires were completed by 304 bachelor/master students (Mage = 22.81 years). Mediations were performed for each dark triad trait with total PSPS and each of its dimensions separately as mediator, and academic burnout as dependent variable. Total PSPS and almost all of its dimensions positively and significantly mediated the relation between Machiavellianism as well as psychopathy and academic burnout (small effect sizes). In contrast, only the PSPS dimension nondisplay of imperfection was a significant, positive mediator of the relation between grandiose narcissism and academic burnout (medium effect size). The other mediations with grandiose or vulnerable narcissism were non-significant. Future research should investigate this further, for instance by using the standard dark triad scales. Finally, this study offers insights for interventions and prevention of academic burnout by highlighting the unique impact of each dark triad trait. For example, those high on Machiavellianism may benefit from tools to deal with cynicism and perfectionism, ultimately lowering the risk for academic burnout.

Psychopathic Traits and Romantic Attachment: The Mediating Role of Emotion Dysregulation.

Objective: Research so far has investigated the bivariate relationships between psychopathic traits, romantic attachment, and emotion dysregulation. However, no research thus far has examined these concepts in their interrelatedness. The aim of the present study was therefore to shed light on the possible linking mechanisms among these concepts, examining the mediating role of emotion dysregulation in the psychopathic traits-romantic attachment link. Method: The present study was based on an undergraduate (N = 238, M age = 20.36 years) and a community sample (N = 521, M age = 35.27 years) from the Dutch population. Participants were administered self-report measures of psychopathic traits (measured with both the Self-Report Psychopathy Short-Form and the Triarchic Psychopathy Measure), emotion dysregulation (Difficulties in Emotion Regulation Scale - Brief Version) and romantic attachment (Experiences in Close Relationships-Revised). Correlation analyses and mediation analyses using a bootstrapping approach were conducted. Results: Results showed that all the dimensions of psychopathic traits were related to both romantic attachment avoidance and anxiety, and that emotion dysregulation mediated all these associations (with only few exceptions). Except for boldness, all other dimensions of psychopathic traits were related to greater emotion dysregulation and, in turn, to insecure romantic attachment. Conclusions: It is argued that the role of emotion regulation processes deserves more attention for the theoretical and clinical understanding of psychopathic traits and their correlates in the interpersonal domain, such as romantic attachment (in)security. When their interrelationships will be better understood, emotion regulation and attachment could represent relevant targets for intervention with individuals presenting psychopathic traits.

Modeling maladaptive personality traits with unipolar item response theory: The case of Callousness.

Most IRT applications in personality assume that the measured trait is a bipolar dimension, normally distributed in the population. These assumptions, however, could be questionable for maladaptive, (quasi) pathological traits that still fall in the normal range. This study focuses on one such trait, Callousness, and uses two different instruments and samples to determine whether there is a basis for modeling it as a unipolar trait instead of a bipolar one. More specifically, the following community samples were used, recruited in several Spanish high schools: a) 719 adolescents (13-19 years old, 55.8% girls), b) 681 adolescents (13-19 years old, 44.9% girls). Callousness was assessed with the Inventory of Callous-unemotional traits and Antisocial behavior in the first sample and with the Inventory of Callous Unemotional traits in the second sample. We compared the outcomes of fitting the Graded-Response model (a bipolar-trait model) and the Log-Logistic model (a unipolar trait model) in these community samples and found that they differed considerably at the scoring level. In terms of accuracy, the conditional reliability functions had opposite patterns: it was maximum at high levels in the Graded-Response model and at low levels in the Log-Logistic model. In terms of validity, the models showed different results regarding the prediction of indirect aggressiveness and non-planning impulsiveness.

The Propensity for Deviant Sexual Behavior in the General Population: An Empirical Examination of the Motivation-Facilitation Model.

In their influential paper Wurtele et al. (2014) investigated the degree to which individuals within the general population (N = 435) express sexual interest in children. In the male population of their study (n = 173), about 6% showed a propensity to engage in sexual activity with a child. Based on a German general population sample consisting of women and men (N = 911, n = 206 males), we were able to replicate most of the results of Wurtele and colleagues (e.g., 6% of men indicated some likelihood of having sex with a child). To explain sexual offending, Seto (2019) developed the motivation-facilitation model (MFM). In our study, we were interested whether this model also translates to explaining the propensity for deviant sexual behavior in the general population. Moderated hierarchical logistic regression analyses revealed that hypersexuality and sexual fantasies had significant effects as motivating factors for deviant sexual behavior (e.g., sexually assaulting an adult), whereas we found no significant effect of psychopathy as a facilitator. For the prediction of child sexual abuse, only hypersexuality had a significant effect. Notably, after including gender in both models the effect of hypersexuality was no longer significant. Accordingly, we were able to show that the MFM is useful in explaining the propensity for deviant sexual behavior foremost in the male general population. Thus, in clinical practice an assessment of hypersexuality seems to be most relevant for the male population.

Gender differences and the association between the phenomenological characteristics of autobiographical memories and psychopathic traits in a university student sample.

The study aimed to analyse the relationship between the dimensions of the triarchic model of psychopathy (meanness, boldness and disinhibition) and the phenomenological characteristics of Autobiographical Memory (AM) in a sample of university students, examining potential gender differences. Participants (N = 260; 55.4% women; aged 18-25) performed an AM task, followed by the Autobiographical Memory Characteristics Questionnaire and the Triarchic Psychopathy Measure. We found gender differences, with men scoring higher than women in meanness and disinhibition as well as in precision, accessibility, sharing and narrative coherence of AM. Correlations showed that boldness was negatively related to the valence and emotional intensity of the memory. Meanness was positively associated with precision, sensory details, accessibility, sharing, narrative coherence, distancing and preoccupation with emotions and negatively with recollection. Disinhibition was positively related to precision, sensory details and accessibility and negatively to intensity, distancing and preoccupation with emotions. Our results suggest that psychopathic traits could predict certain characteristics of AM, highlighting the predictive value of meanness, especially regarding memory quality characteristics (e.g., precision), as well as disinhibition, concerning the emotional content (e.g., preoccupation with emotions). Our results contribute to understanding psychopathy through an autobiographical perspective, showing how psychopathic traits may shape how people remember personal events.

Psychopathy and medial frontal cortex: A systematic review reveals predominantly null relationships.

Theories have posited that psychopathy is caused by dysfunction in the medial frontal cortex, including ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex (ACC), and dorsomedial prefrontal cortex (dmPFC). Recent reviews have questioned the reproducibility of neuroimaging findings within this field. We conducted a systematic review to describe the consistency of magnetic resonance imaging (MRI) findings according to anatomical subregion (vmPFC, ACC, dmPFC), experimental task, psychopathy assessment, study power, and peak coordinates of significant effects. Searches of PsycInfo and MEDLINE databases produced 77 functional and 24 structural MRI studies that analyzed the medial frontal cortex in relation to psychopathy in adult samples. Findings were predominantly null (85.4 % of 1573 tests across the three medial frontal regions). Studies with higher power observed null effects at marginally lower rates. Finally, peak coordinates of significant effects were widely dispersed. The evidence failed to support theories positing the medial frontal cortex as a consistent neural correlate of psychopathy. Theory and methods in the field should be revised to account for predominantly null neuroimaging findings.

Psychopathy, criminogenic cognitions and emotional responses to affective stimuli among male adult offenders.

BACKGROUND: Previous research has consistently shown value in studying emotion processing with psychopathy, but the relative effect of aural and visual stimulation has hardly been considered. AIMS: Our aims were to (1) compare reaction time and self-rated valence ((un)pleasantness), arousal and sense of being dominated by affective sounds or visual images among offenders with and without psychopathy (=/>26) on the psychopathy check-list revised; (2) investigate any associations, controlling for social desirability and depression; (3) explore the possible mediating effect of criminogenic cognitions on any relationships between psychopathy and emotional responses to affective stimuli. METHODS: Professional educators invited all male offenders serving semi-open custody sentences in one prison to participate. After a semi structured interview to assess psychopathy, they self-reported on criminogenic cognition, depression and social desirability scales, before a computer task using standardised human and animal sounds and images. Using the self-assessment manikin, participants rated the emotional valence, arousal and dominance levels when pleasant, unpleasant and neutral sounds or images were presented. RESULTS: About one in three prisoners completed all the ratings-120 men, of mean age 38.8 years (SD = 11.06). All had shorter reaction times to sounds than images. Offenders with high affective-interpersonal factor scores rated all types of sounds as less pleasant. Men with high psychopathy scores took longer to respond to unpleasant images than those with lower scores. There was a positive relationship between psychopathy factors and criminogenic cognitions and the external locus of criminogenic cognitions mediated the relationship between psychopathy facets and emotional responses of valence to pleasant sounds. CONCLUSION: Our findings confirm the potential importance of emotional reactions to sounds as well as images among men with psychopathy. Given the shorter reaction times to sounds, in real life sounds could prove more provocative than images. While only small differences emerged between men above and below the PCL-R threshold, indications from facet analyses suggest that further study of sound stimuli could enhance the understanding of emotional response differences to inform interventions. Future research in this area should focus on human-related stimuli and add alexithymia measures.

Psychopathy traits explain variance shared between features of substance use disorders and violence.

BACKGROUND: There is a substantial research literature on identifying risk and protective factors for violence perpetration. Substance use disorders have long been identified as constituting a significant predictor of violent behaviour. Psychopathy traits have also been similarly recognised, but inter-relationships between psychopathy traits, features of substance use disorders and violence have been little explored. AIMS: To determine the degree to which shared variance between substance dependence symptoms and violence, as indicated by criminal charges for violent offences, among jailed men can be explained by psychopathy traits. METHODS: Features of dependence on substances in three drug classes (alcohol, cannabis and cocaine) were assessed in a sample of 682 men in a county jail awaiting trial on criminal charges, many for violent offences. Statistical comparisons of zero-order and partial correlations tested whether accounting for psychopathy total and facet scores, assessed by the Psychopathy Checklist-Revised (PCL-R), affected associations between substance dependence symptoms and violent charges. RESULTS: Total PCL-R scores accounted for a significant proportion of the shared variance between the history of criminal charges for violence offences and lifetime substance dependence symptoms in all three drug classes. At the facet level, controlling for ratings on the interpersonal and modified antisocial facets reduced the association between criminal charges for violent offences and symptoms of cocaine dependence; controlling for ratings on a modified antisocial facet also attenuated links between alcohol and cannabis dependence symptoms and history of charges for violent offences. CONCLUSION: These findings build on the sparse literature to date on the role of psychopathy traits on relationships between features of substance use disorders and violence. Given that the observed connection between substance dependence symptoms and charges for violent offences is partly accounted for by individual differences in psychopathy traits, it follows that effective treatment for those traits may be useful, perhaps essential to reducing links between features of some substance use disorders and violent offending.

Do autism and psychopathy co-occur? A systematic review and clinical discussion.

BACKGROUND: Although the prevalence is unknown, psychopathy can be a possible co-occurring condition associated with autism especially among forensic populations. However, the relationship between these two conditions remains poorly understood. AIMS: To carry out a systematic review of the available literature exploring the relationship between autism and psychopathy. METHODS: A systematic literature review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using terms for autism and psychopathy to search the literature databases Scopus, Pubmed, Web of Science, ASSIA, APA Psych Info, Medline and EMBASE from 1980 to March 2024. For inclusion, we required that a recognised measure of autism and psychopathy or associated features of the latter had been used. RESULTS: Of the 4230 potential articles identified, 37 met the selection criteria. Insufficient and inconsistent methodologies for data pooling meant that a narrative analysis was used. Although there is some overlap, four broad themes emerged relating to (1) assessment and frequency of co-occurrence, (2) behavioural and neurophysiological expressions of empathy, (3) behavioural contagion effects, mirroring, mimicry and other linking mechanisms and (4) emotional face perception and theory of mind characteristics. Within these areas there are some specific differences between the two conditions. However, the research to date examining the relationship between autism and psychopathy has mostly been with children and males, carried out with non-clinical non-forensic populations, as well as using self-report measures and parental ratings. Prior research has also largely focused on looking for differences between these conditions rather than co-occurrence. CONCLUSION: This review outlines a case for considering autism and psychopathy as distinct, but potentially co-occurring conditions and highlights the need for more research into how the two conditions interact with clinical populations. There also appears to be a need for guidelines on when and how to assess psychopathy with autistic individuals and a better understanding of the therapeutic needs and factors influencing the long-term outcomes of autistic individuals who may also present with co-occurring psychopathy.

Reliability and Validity of the Comprehensive Assessment of Psychopathic Personality-Self-Report-German Version (CAPP-SR-GV) in a German Non-Criminal Sample.

The structure of psychopathy is conceptualized differently in various models and no consensus has yet been reached. This study aimed to further clarify psychopathy's content and structure by validating the German Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR). For this purpose, we used a sample of n = 458 participants. The CAPP's six factors were replicated in an exploratory factor analysis. Further confirmatory analysis revealed recommendations for optimizing the CAPP. Thus, both an optimized version and the original CAPP-SR were examined. The construct validity of both versions was then examined using a different self-rating instrument for psychopathy, the Triarchic Psychopathy Measure. The implications of the findings and further research directions are discussed.

Perception of emotional facial expressions in aggression and psychopathy.

BACKGROUND: Altered affective state recognition is assumed to be a root cause of aggressive behavior, a hallmark of psychopathologies such as psychopathy and antisocial personality disorder. However, the two most influential models make markedly different predictions regarding the underlying mechanism. According to the integrated emotion system theory (IES), aggression reflects impaired processing of social distress cues such as fearful faces. In contrast, the hostile attribution bias (HAB) model explains aggression with a bias to interpret ambiguous expressions as angry. METHODS: In a set of four experiments, we measured processing of fearful and angry facial expressions (compared to neutral and other expressions) in a sample of 65 male imprisoned violent offenders rated using the Hare Psychopathy Checklist-Revised (PCL-R, Hare, R. D. (1991). The psychopathy checklist-revised. Toronto, ON: Multi-Health Systems) and in 60 age-matched control participants. RESULTS: There was no evidence for a fear deficit in violent offenders or for an association of psychopathy or aggression with impaired processing of fearful faces. Similarly, there was no evidence for a perceptual bias for angry faces linked to psychopathy or aggression. However, using highly ambiguous stimuli and requiring explicit labeling of emotions, violent offenders showed a categorization bias for anger and this anger bias correlated with self-reported trait aggression (but not with psychopathy). CONCLUSIONS: These results add to a growing literature casting doubt on the notion that fear processing is impaired in aggressive individuals and in psychopathy and provide support for the idea that aggression is related to a hostile attribution bias that emerges from later cognitive, post-perceptual processing stages.

Pathways from Family Functioning to Internet Gaming Disorder: The Mediating Role of the Dark Triad.

With internet gaming disorder (IGD) becoming more common, there are growing worries about the health of those it affects. This study examines how traits like Machiavellianism, psychopathy, and narcissism might connect family functioning to IGD. The research involved 1190 young adults who answered an online survey, sharing their personal experiences. To examine the mediation effects, latent variable structural equation modeling (SEM) was used, revealing complex relationships among the variables under investigation. Although all direct and indirect paths were statistically significant, the mediation effects of narcissism were positive only when Machiavellianism and psychopathy were not included as parallel mediators, but negative otherwise. The findings suggest that individuals with strong family functioning could be less likely to internalize manipulative behaviors and show a lack of empathy, traits that could contribute to their involvement in IGD. The results underscore the importance of recognizing the multifaceted nature of this phenomenon and provide valuable insights for developing comprehensive strategies to prevent and tackle IGD. Therefore, prevention and intervention efforts should consider the combined influences of family functioning, personality traits, and individual and contextual factors in the online environment to effectively address this problem.

Psychopathic Traits in Adult versus Adolescent Males: Measurement Invariance across the PCL-R and PCL:YV.

Both the Psychopathy Checklist-Revised (PCL-R) and the Psychopathy Checklist: Youth Version (PCL:YV), respectively, are established instruments for assessment of psychopathy and development of psychopathic propensity. To reliably compare scores from both instruments, measurement invariance must be established. The current study involved a combined sample of 1091 male participants (adults = 813; adolescents = 278) from correctional facilities in New Mexico. An exploratory structural equation modeling (ESEM) framework was used to test for measurement invariance. The four-factor ESEM model demonstrated good fit for the combined and individual samples. Results from the multiple group ESEM provide evidence for generally strong invariance, with equivalent factor loadings and thresholds. Adolescents exhibited decreased latent interpersonal traits but increased latent features on other PCL factors (affective, lifestyle, and antisocial) compared to adults. Findings suggest that the four-factor model and the measurement of psychopathic traits remain consistent across age groups. Implications of the findings within research and clinical contexts are discussed.

Psychopathy and Impairments in Emotion Regulation: A systematic review and Meta-analysis.

Considering the sparse but rapidly growing literature concerning the relationship between psychopathy and emotion regulation, taking stock of accumulating knowledge in a systematic review and meta-analysis of the existing results is needed. We performed a systematic search (up to May 30, 2024) following PRISMA guidelines of five scientific databases (PsycINFO, PsycARTICLES, MEDLINE, PubMed, Scopus and Web of Science). Also, gray literature was searched. After removing the duplicates, a total of 8.786 records were screened, and 73 articles were selected based on the inclusion criteria used for systematic review. The meta-analytic procedure was performed on 55 identified studies consistent with the criteria adopted, which overall comprised 29.856 individuals. The current systematic and meta-analysis review has clarified the association between impairments of emotional regulation abilities and facets of psychopathy. More specifically, analyses indicated that emotional dysregulation is associated with overall levels of psychopathic traits, as well as with both the lifestyle and affective components of psychopathy, which suggests the utility of assessing these features when designing interventions focused on modulating negative emotional states and enhancing regulation of impulsive behaviors.

The Effects of Psychopathy Facets on Treatment Involvement.

The current study explored the relations between patient characteristics and psychopathic traits in predicting treatment involvement. We rated treatment involvement using detailed archival clinical files of 218 individuals committed to the Massachusetts Treatment Center (MTC). Psychopathy Checklist-Revised (PCL-R) scores had been rated from a previous study on the same sample. Overall, PCL-R Facets 2 and 4 significantly predicted decreases in treatment involvement, suggesting the characteristics associated with these facets have the most disruptive effects on treatment involvement. Exploratory analyses were also conducted assessing the relations between the PCL-R facets and the individual treatment involvement components. Whereas Facet 2 significantly predicted lower levels in all three individual treatment involvement components, Facet 4 only significantly predicted lower levels in two, highlighting the differentiating effects of these facets. Identifying the components that have either positive or negative effects on treatment involvement can allow clinicians to tailor treatments to optimize treatment involvement and outcome.

Personality factors and pandemic-related behaviors.

Purpose: The purpose of the current study was to determine whether there are personality differences (the HEXACO model, narcissism, sadism, compassion for others) in mask-wearing, social distancing, and hoarding. Findings: Those who always wore masks were significantly higher in compassion for others and significantly lower in sadism compared to those who did not always wear masks. Those who always socially distanced (compared to those who did not) were significantly higher in openness, compassion for others, and conscientiousness. Those who hoarded were significantly lower in agreeableness than those who did not hoard. Conclusion: Perhaps physicians may use information to boost states of altruistic-type traits (agreeableness, compassion for others) while educating patients during visits in order to increase the likelihood of receiving vaccinations or booster shots.

Fair-Weather Voters: Personality and Vote Switching Intentions.

While numerous explanations for vote-switching have been proposed (e.g. declining rates of partisanship, ideological shifts, partisan ambivalence, change in policy preferences), far less work has examined the personality profile of people more likely to engage in this behaviour. In Study 1, we examined the relationship between both general (i.e. openness, conscientiousness) and antagonistic (i.e. psychopathy, narcissism, Machiavellianism) personality traits and the intent to switch one's vote in a large sample of Canadian citizens, while controlling for several established correlates such as age, income and political interest. Of all personality traits, only individuals higher in openness reported a greater intent to engage in vote switching. Despite our expectations, Machiavellianism, a trait characterized by its strategic nature, was unrelated to vote switching intentions. In Study 2, we addressed several methodological reasons for why antagonistic traits may have been unrelated to vote switching intentions in Study 1 by examining the traits at the facet level and utilizing a new measure of Machiavellianism among a separate sample of Canadian citizens. Here again, we found little evidence for a relationship between antagonistic traits, including Machiavellianism, and vote switching intentions.
