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.

Longitudinal trajectory classes and correlates of the Multidimensional Personality Questionnaire-triarchic psychopathy scales from adolescence to young adulthood

The present study examined longitudinal trajectory classes and correlates of triarchic psychopathy domains (boldness, meanness, and disinhibition) from age 16 to 22, leveraging Multidimensional Personality Questionnaire (MPQ)-based triarchic scales data gathered on a large community sample (ns ranging between 483 and 775 across waves) oversampled for parental substance use disorder (SUD). Growth mixture models were conducted to examine longitudinal trajectory classes for each domain, and their associations with environmental covariates (e.g., neighborhood disadvantage and parental SUD) and outcomes at age 22 (e.g., violent behavior, antisocial personality disorder, and an overall problem index capturing internalizing symptoms and social problems). For boldness, all participants fell in the same class showing relative stability over time. Comparable solutions were recovered for meanness and disinhibition (high-stable/increasing, mid-range decreasing, and low-decreasing). Links with external correlates supported well-known differences between boldness and both meanness and disinhibition and additionally revealed interesting differences between meanness and disinhibition, suggesting that environmental covariates better discriminated meanness trajectory classes. These results demonstrate considerable developmental heterogeneity in these traits across adolescence into young adulthood, which relates to outcomes associated with antisociality and general life struggles. Further, these findings support the adequacy of the MPQ as an operationalization tool for longitudinal investigations on psychopathy.

Psychopathy, pain, and pain empathy: A psychophysiological study

The present study examined whether people higher in psychopathy experienced less self-reported and psychophysiological nociceptive pressure than people lower in psychopathy. We also examined whether psychopathy affects empathy for others' pain via self-reported and psychophysiological measures. Three hundred and sixty-nine students (18-78 years; M = 26, SD = 9.34) were screened for psychopathic traits using the Youth Psychopathy Inventory (YPI). Stratified sampling was used to recruit 49 adults residing in the highest (n = 23) and lowest (n = 26) 20% of the psychopathy spectrum. Using skin conductance response (SCR) and self-report responses, participants responded to individually adjusted intensities of pneumatic pressure and others' pain images and completed self-reported psychopathy and empathy measures (Triarchic Psychopathy Measure, TriPm; Interpersonal Reactivity Index, IRI). People higher in psychopathy self-reported feeling less nociceptive pressure compared to people lower in psychopathy, yet we did not find any differences in SCR to nociceptive pressure. However, when viewing other people in pain, the high psychopathy group displayed lower SCR and lower self-reported empathy compared to those lower in psychopathy. Our results suggest psychopathic traits relate to problems empathising with others' pain, as well as the perception of nociceptive pressure. We also show support for the theory of dual harm which has been receiving increasing attention. Consequently, psychopathy interventions should focus both on recognising and empathising with the pain of others.

Clinical cut scores for the Persian version of the personality inventory for DSM-5

BACKGROUND

The cut points of psychological tools to diagnose clinical conditions are not universal and depend on the region and prevalence of the disorder. Thus, we aimed to identify the cutoff points of the Persian original version of the personality inventory for DSM-5 (PID-5; 220 items) that would optimally distinguish nonclinical from clinical groups.

METHODS

Both nonclinical (N = 634, 73% female, 34.0 ± 10.8 years) and clinical (N = 454, 29% female, 29.5 ± 7.4 years) samples from the West of Iran participated in the study. Data were analyzed using receiver operating characteristic (ROC) and Youden's index was used to determine the cutoff scores across the PID-5 domains and facets. The means and standard deviations of both the clinical male and female were compared with the nonclinical group using Cohen's d and independent t-tests.

RESULTS

All the PID-5 algorithms and facets significantly distinguished clinical from nonclinical samples with some unique findings for male and female samples. The mean score of all the PID-5 algorithms and facets in the clinical male and female samples were respectively 1.0-2.0 SD and 0.5-1.0 SD above the mean for the nonclinical counterparts. A score higher than 1.5 on ranging from 0 to 3 in each domain or facet indicated clinical status.

CONCLUSION

Raw cutting scores throughout the PID-5 algorithms can be well used to diagnose any pathology of personality and the severity of the disorder in clinical patients. The cut scores provide a useful tool for the clinical use of the original version of PID-5 in Iran.

Diagnosing callous-unemotional personality traits by heart rate orienting responses to images inducing threat and distress

The present study aimed at developing a rather easily applicable method of testing physiological reactions to images of threats and misery. To this end, rapid-changing, transient heart rate orienting responses were used for gaining physiologically based, objective responses to the images. Additionally, subjective ratings were obtained. A significant insensitivity to other's welfare and well-being was already demonstrated as a core feature of callous-unemotional personalities. Thus, physiologically based methods may supplement and possibly improve existing assessments and, in particular, may contribute to a multimodal assessment of psychopathic traits. Out of a non-forensic community sample of 122 men, we selected two extreme groups of 30 participants with the lowest and highest callous-unemotional traits respectively, ascertained by questionnaires. As expected, participants with higher scores of callous-unemotional traits showed smaller responses to distress cues in both heart rate responses and subjective ratings. Moreover, within the group with high callous-unemotional traits heart rate responses to threatening as well as distress cues did not significantly differ from responses to neutral pictures. The study provides further evidence for the idea that a lack of responsiveness to distress cues may be seen as a central feature of callous-unemotional personalities.

Blunted startle reactivity in everyday sadism and psychopathy

Two studies examined the amplitude of the startle response as a function of the Dark Tetrad of personality (narcissism, Machiavellianism, psychopathy, and sadism). We measured electromyographic activity of the orbicularis oculi muscle evoked by a startle stimulus while participants viewed images on a computer screen. Both studies revealed a negative correlation between general startle reactivity (averaged across positive, negative, and neutral images) and sadistic tendencies. In Study 2, all four dark traits were negative correlates of general startle reactivity. Study 2 also examined the personality correlates of aversive startle potentiation (ASP; indexed by greater reactivity while viewing negatively-valenced images than positive or neutral images). ASP correlated negatively with a variety of personality measures of psychopathy and sadism, their facets, and related personality tendencies (callousness, risk-taking, and restricted affect). These findings suggest that ordinary people with high levels of callousness and antagonism display physiological evidence of non-reactivity (i.e., blunted acoustic startle in general), whereas psychopathy and sadism are preferentially associated with reduced ASP.

Contemporary diagnosis and treatment of conduct disorder in youth

INTRODUCTION

Conduct disorder (CD) is characterized by repetitive and persistent antisocial behaviors, being among the most frequently reported reasons of referral in youth. CD is a highly heterogeneous disorder, with possible specifiers defined according to age at onset, Limited Prosocial Emotions (LPE) otherwise known as Callous-Unemotional (CU) traits, Emotional Dysregulation (ED), and patterns of comorbidity, each with its own specific developmental trajectories.

AREAS COVERED

The authors review the evidence from published literature on the clinical presentations, diagnostic procedures, psychotherapeutic and psychoeducational approaches, and pharmacological interventions from RCT and naturalistic studies in youth. Evidence from studies including youths with LPE/CU traits, ED and aggression are also reviewed, as response moderators.

EXPERT OPINION

Due to its clinical heterogeneity, relevant subtypes of CD should be carefully characterized to gain reliable information on prognosis and treatments. Thus, disentangling this broad category in subtypes is crucial as a first step in diagnosis. Psychosocial interventions are the first option, possibly improving LPE/CU traits and ED, especially if implemented early during development. Instead, limited information, based on low-quality studies, supports pharmacological options. Second-generation antipsychotics, mood stabilizers, and stimulants are first-line medications, according to different target symptoms, such as aggression and emotional reactivity. Developmental pathways including ADHD suggest a specific role of psychostimulants.

Construct Validity of Triarchic Model Traits in the Dunedin Multidisciplinary Health and Development Study Using the Multidimensional Personality Questionnaire

The triarchic model of psychopathy emphasizes the role of three phenotypic personality domains (boldness, meanness, and disinhibition) that have been operationalized using the well-established Multidimensional Personality Questionnaire. The present study sought to further validate the MPQ-Tri scales and examine their temporal stability and predictive validity across two time points (ages 18 and 26) from the Dunedin Multidisciplinary Health and Development Study, a population-representative and longitudinal sample (N = 1,037). This investigation necessitated modification of the MPQ-Tri scales to enable their use in a broader range of samples, including the Dunedin Study. The revised MPQ-Tri scales demonstrated good temporal stability, and correlation and multiple linear regression analyses predominantly revealed associations consistent with theoretical expectations. Overall, the findings provide support for the MPQ-Tri scales as reliable, stable, and valid measures of the triarchic constructs, which provide a unique opportunity to examine highly novel research questions concerning psychopathy in a wide variety of samples.

Parental Antisocial and Psychopathic Traits Influence Adolescent Psychopathology

The role of parental antisocial behavior in the development of adolescent psychopathology is well established in the literature. However, less is known about the role of parental psychopathic traits in offspring psychopathology. Adolescents (N = 210; boys = 107) and their parents participated in a study measuring parental antisocial behavior, psychopathic traits (i.e., callous-unemotional traits, impulsive-irresponsibility, and grandiosity), and adolescent psychopathology, including depression, anxiety, attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Results from the structural equation model suggested that maternal antisocial acts, but not anger propensity, positively predicted adolescent CD, ODD, and depressive symptoms. Paternal anger propensity mainly predicted internalizing problems, whereas paternal impulsive-irresponsibility predicted anxiety and ADHD symptoms. In addition, findings pointed to several indirect effects from maternal and paternal psychopathic traits to adolescent psychopathology, with the strongest one being between maternal impulsive-irresponsibility to maternal antisocial acts to adolescent ODD. The findings suggest that parental antisocial behaviors and psychopathic traits, and especially impulsive-irresponsibility, should be considered in interventions aiming to reduce adolescent psychopathology.

Difficulties in facial emotion recognition: taking psychopathic and alexithymic traits into account

BACKGROUND

Alexithymic and psychopathic traits are closely associated, but distinct constructs. Both have been associated with facial emotion processing deficits reflecting empathy deficits, however the underlying mechanism contributing to these deficits is not well-understood.

METHODS

This study investigated facial emotion recognition performance in a non-clinical sample (N = 110) including both male and female participants, with varying levels of psychopathic and alexithymic traits. Facial emotion recognition was assessed using a computerized task, that presented different expressions depicting five emotional states (pain, fear, sadness, anger, happiness) and neutral expressions.

RESULTS

Results suggest that the high psychopathic traits group reported lower accuracy compared to the low psychopathic traits group, indicating a more generalized deficit in facial affect recognition, across all emotions. The alexithymic groups (high vs. low) on the other hand did not differ in their performance on the task for any of the emotions presented.

CONCLUSION

These findings add to the current body of research regarding face processing categorization deficits in relation to psychopathic and alexithymic traits and can inform prevention and intervention efforts that aim to facilitate facial emotion recognition in individuals with these personality traits.

Understanding the Social Relationships of Youth with Callous-Unemotional Traits Using Peer Nominations

OBJECTIVE

The current study investigated the social and interpersonal correlates of callous-unemotional (CU) traits using peer nominations.

METHOD

Participants (N = 289) were children in Grades 3, 6, and 8 (Mage = 11.47 years, 40.1% male, 64.7% self-identified racial/ethnic minority) from two public school systems in the southern United States. Participants were asked to identify peers they believed fit a number of different characteristics hypothesized to be related to CU traits, in addition to individuals they "liked most" and "liked least." We also obtained self- and teacher ratings of CU traits and parent and teacher ratings of conduct problems (CP).

RESULTS

Factor analyses extracted three dimensions from peer nominations developed from past research describing social characteristics related to CU traits-being mean and aloof (Mean/Cold), untrustworthy and not nice (Not Nice), and dominant and manipulative (Desire for Dominance). Results indicated that CU traits were significantly associated with fewer "liked most" and greater "liked least" nominations, but not after controlling for CP. In contrast, both CP and CU traits were significantly independently associated with Mean/Cold nominations, and only CU traits were associated with Not Nice nominations when controlling for CP.

CONCLUSIONS

The findings from the current study suggest that CU traits are largely associated with traditional indices of peer rejection because of their level of CP. However, they contribute independently to perceptions of being mean, aloof, and untrustworthy. Thus, interventions focused on strengthening the social skills of children with elevated CU traits should consider ways to change these negative peer perceptions.

Psychopathic Personality in Early Childhood: A Critical Comment on Lopez-Romero et al. (2021)

A recent article published in the Journal of Personality Disorders (López-Romero et al., 2021) described the identification of "putative psychopathic personality" in a school cohort of 3-6-year-old children from Spain. This comment offers cautionary considerations of the original article on scientific grounds and critical comments on policy grounds. We caution researchers, policymakers, attorneys, judges, and the general public about the dangers of using this label given present knowledge about the antecedents, early indicators, and stability of the adult disorder of psychopathic personality when assessed in childhood.

Triarchic Model Traits as Predictors of Bullying and Cyberbullying in Adolescence

The triarchic model of psychopathy includes a disinhibition dimension related to externalizing outcomes, a meanness dimension pertaining to callous-unemotional traits, and a boldness dimension referring to emotional stability and high confidence in peer relationships. Some dimensions of psychopathy have been extensively investigated in samples of children and adolescents; in particular, the callous-unemotional (meanness) dimension has been associated with aggression and bullying in numerous studies. However, the other dimensions of the triarchic model have been relatively unexplored in samples of adolescents. Thus, we tested for associations between the triarchic dimensions and bullying and cyberbullying behaviors (i.e., proactive, goal-directed, and repetitive aggressive behaviors) in a sample of 580 high school students aged 14 to 19 years. Logistic regression analyses showed that (a) meanness and disinhibition scores were uniquely associated with traditional bullying, whereas only meanness was uniquely associated with cyberbullying; (b) boldness scores moderated the relationship between disinhibition and cyberbullying, such that disinhibition was related to cyberbullying only at low levels of boldness; and (c) these patterns were maintained when accounting for overall levels of conduct problems and were not moderated by the experience of victimization. Our findings suggest that the triarchic model of psychopathy can contribute to an understanding of youth engagement in bullying and cyberbullying.

Psychopathy: Current Knowledge and Future Directions

Research on psychopathy has progressed considerably in recent years against the backdrop of important advances in the broader field of clinical psychological science. My major aim in this review is to encourage integration of investigative work on dispositional, biobehavioral, and developmental aspects of psychopathy with counterpart work on general psychopathology. Using the triarchic model of psychopathy as a frame of reference, I offer perspective on long-standing debates pertaining to the conceptualization and assessment of psychopathy, discuss how dispositional facets of psychopathy relate to subdimensions of internalizing and externalizing psychopathology, and summarize findings from contemporary biobehavioral and developmental research on psychopathy. I conclude by describing a systematic strategy for coordinating biobehavioral-developmental research on psychopathy that can enable it to be informed by, and help inform, ongoing research on mental health problems more broadly. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Reading and reacting to faces, the effect of facial mimicry in improving facial emotion recognition in individuals with antisocial behavior and psychopathic traits

Individuals with antisocial behavior and psychopathic traits are characterized by deficits in processing facial expressions, which results in poor social adaptation and dysfunctional interpersonal relationships. However, it is not clear how individuals with varying levels of these traits differ in this emotional impairment and if these deficits are due to correctly identifying or reacting appropriately to facial expressions. The aim of the study was to examine how individuals with these traits recognized and responded to affective facial expressions by using FaceReader software (which analyses footage of faces) across different experimental conditions (imitation, suppression, and control). Imitating facial expressions was introduced to examine whether it could direct participants’ attention to the facial cues and improve participants’ performance on the facial task. A total of 643 individuals from the community were pre-screened and a sample (N = 107; M age = 21.08, SD = 1.55), differentiated on levels of antisocial personality disorder (APD) symptoms and psychopathic (PSY) traits, who were selected based on extreme scores (high/low), were invited to participate in the study. Individuals with higher levels of APD symptoms and PSY traits (APD + PSY) expressed more anger than other groups, while those in the APD-only group expressed more sadness, compared to other groups. Overall, participants were compliant in following the instructions to imitate facial expressions. However, only the group with predominantly APD symptoms and the group with combined symptoms (APD + PSY) showed improvement in their accuracy ratings specifically when instructed to imitate facial expressions, compared to when no instructions were provided. The study offers a promising direction for targeting deficits in facial emotion recognition, suggesting that the deficits found in individuals with behavioral problems (with and without psychopathic traits) can be improved by asking them to imitate facial expressions.

Understanding Emotion Regulation and Humor Styles in Individuals with Callous-Unemotional Traits and Alexithymic Traits

Alexithymia is a personality trait which is characterized by impairments in identifying and describing emotions. Both psychopathic and alexithymic personality traits have been associated with impairments in emotion processing. This study aims to clarify the conceptual overlap between psychopathic traits (focusing on callous-unemotional traits) and alexithymic traits, with emotion regulation strategies and humor styles using a community sample. A battery of self-report measures was distributed through an online platform to 538 male and female participants between the ages of 18 to 65. Hierarchal linear regression analyses demonstrated that emotion regulation strategies were the strongest predictors and accounted for the largest variance of callous-unemotional traits and alexithymic traits. More specifically, expressive suppression arose as a positive predictor while cognitive reappraisal arose as a negative predictor for both personality traits. Aggressive humor (maladaptive) arose as a positive predictor while self-defeating humor (maladaptive) and affiliative humor (adaptive) arose as negative predictors for callous-unemotional traits. In contrast, self-defeating humor arose as a positive predictor for alexithymic traits while affiliative humor and self-enhancing humor arose as negative predictors. Findings indicate that there are similarities and differences between these personality traits. The implications regarding tailoring interventions that target specific deficits associated with each personality trait are discussed.

Investigating the Validity Evidence of the Swedish TriPM in High Security Prisoners Using the PCL-R and NEO-FFI

The triarchic model of psychopathy was developed to bridge opposing descriptions of psychopathy by separating the core construct in three domains; boldness, meanness, and disinhibition. The Triarchic Psychopathy Measure (TriPM) operationalizes the model through a 58-item self-report questionnaire. The current study examined the psychometric properties of the Swedish translation by investigating intercorrelations and associations to expert-rated psychopathy, general personality and psychopathy-related traits in male high-security prisoners (n = 191). Psychopathy rated with TriPM and the Psychopathy Checklist Revised (PCL-R) demonstrated expected convergence, as did empathy and impulsivity measures. The Disinhibition and Meanness scales were highly correlated, indicating that the scales might not be adequately differentiated. Nevertheless, the divergent association patterns to other important variables, particularly neuroticism and empathy, also points to meaningful differences. However, the lack of association between Disinhibition and Boldness may put into question if these domains are related at all, especially since there was a lack of similarity in the association patterns with other clinical variables. The influence of antisocial behavior in the TriPM operationalization might amplify the similarities of the Meanness and Disinhibition scales, while diluting the associations between Meanness and Boldness. In conclusion, the Swedish TriPM is effective in measuring the domains of triarchic model in forensic settings, even though a revision of the scales might improve the psychometric properties of the instrument.

Heart Rate and Skin Conductance Associations with Physical Aggression, Psychopathy, Antisocial Personality Disorder and Conduct Disorder: An Updated Meta-Analysis

The associations between physiological measures (i.e., heart rate and skin conductance) of autonomic nervous system (ANS) activity and severe antisocial spectrum behavior (AB) were meta-analyzed. We used an exhaustive partitioning of variables relevant to the ANS-AB association and investigated four highly relevant questions (on declining effect sizes, psychopathy subscales, moderators, and ANS measures) that are thought to be transformative for future research on AB. We investigated a broad spectrum of physiological measures (e.g., heart rate (variability), pre-ejection period) in relation to AB. The search date for the current meta-analysis was on January 1^st, 2020, includes 101 studies and 769 effect sizes. Results indicate that effect sizes are heterogeneous and bidirectional. The careful partitioning of variables sheds light on the complex associations that were obscured in previous meta-analyses. Effects are largest for the most violent offenders and for psychopathy and are dependent on the experimental tasks used, parameters calculated, and analyses run. Understanding the specificity of physiological reactions may be expedient for differentiating between (and within) types of AB.

Heart-wired to be cold? Exploring cardiac markers of callous-unemotional traits in incarcerated offenders

Elevated callous-unemotional (CU) traits have been repeatedly identified in a subgroup of offenders that displays severe antisocial behavior; establishing physiological markers may help improve early identification and treatment efforts. This study examines to what extent baseline-resting heart rate (HR) and heart rate variability (HRV) can be used as markers of CU in incarcerated juvenile and adult offenders. CU traits were assessed using the Inventory of Callous-Unemotional traits. Results of the multiple hierarchical regression tests indicated that there was a small yet significant positive association between baseline HR and CU and negative association between HRV and CU in juvenile offenders with medium model effect sizes (R² = 0.115 for HR-CU; R² = 0.126 for HRV-CU). The cardiac markers were unrelated to CU in adult offenders. These findings are important because they demonstrate that impaired cardiac autonomic activity is related to CU traits in juveniles, suggesting that socioemotional processing difficulties should be considered in understanding these deficits. Future research should be conducted in large samples, under reactive and static conditions, while including cardiac covariates, to get more clarity on the interplay between biological systems and behavioral expression.

Dispositional characteristics in firearm ownership and purchasing behavior during the 2020 purchasing surge

RATIONALE

In 2020 the U.S. saw a firearm purchasing surge that was synchronous with the onset of the SARS-CoV-2 (COVID-19) pandemic and notable community unrest. Extant literature has highlighted a potential cohort effect among 2020 firearm purchasers and the importance of characterizing these individuals to inform policy and interventions. Dispositional traits have received minimal attention in the firearm literature overall, despite research that indicates dispositional traits impact intervention interest, access, and effectiveness.

OBJECTIVE

The current study examined two dispositional traits indicated as important in firearm research - threat sensitivity (THT) and disinhibition (DIS). We hypothesized that 1) firearm owners overall would have lower THT and higher DIS relative to non-firearm owners, 2) mean levels of DIS (but not THT) would be higher among firearm owners who purchased during the 2020 purchasing surge relative to firearm owners who did not and non-firearm owners, and 3) DIS (but not THT) would be related to future plans for purchasing such that mean levels of DIS would be highest amongst those who have plans.

METHODS

This study used an online-recruited sample (N = 3500) matched to 2010 US Census data.

RESULTS

Firearm owners demonstrated lower THT and higher DIS than non-firearm owners. 2020 firearm purchasers had higher DIS compared to non-firearm owners and non-purchasing firearm owners, while firearm owners who did not purchase had lower THT compared to non-owners and 2020 purchasers. Plans to purchase in the next 12 months was associated with higher DIS relative to those undecided or without plans.

CONCLUSIONS

In combination with prior research, findings suggest elevated DIS may drive purchasing as a danger and distress management strategy, while low THT may protect against emotion-based firearm purchasing. Further research is needed to clarify the directionality of these relationships and to identify other dispositional characteristics of those purchasing firearms in 2020.

Give me your password! What are you hiding? Associated factors of intimate partner violence through technological abuse

The present study explored the associated factors of intimate partner violence through technological abuse (ITPV) in a sample of 1113 participants aged 18 to 65 (71.3% females). Our research's primary questions were the following: 1). Is there a significant link between relationship attachment styles and ITPV perpetration or victimization?; 2). Is there a significant link between participants' demographic and relationship characteristics (i.e., relationship length and partners' fidelity), online behavior (i.e., benign and toxic disinhibition), moral disengagement, psychological distress), and ITPV perpetration or victimization?; and 3). Did the COVID-19 pandemic increase ITPV perpetration or victimization?. We analyzed our data by creating three different groups, depending on participants' answers concerning ITPV, i.e., the overall sample, abusers' and victims' groups. Our main results suggested significant, positive correlations between ITPV perpetration and victimization, moral disengagement, psychological distress, and online disinhibition. Age negatively correlated with IPVT victimization and perpetration. We also found significant associations between participants' dominant relationship attachment style and their own and partners' cheating behavior, as well as ITPV-victimization and perpetration. Finally, 13.7% to 23% of participants in all three groups considered that the Covid-19 increased the frequency of ITPV behaviors (for both abusers and victims). Results are discussed considering their theoretical and practical implications for domestic violence and the potential related prevention and intervention strategies.

Adult attachment and psychopathic traits: Investigating the role of gender, maternal and paternal factors

Individuals with psychopathic traits have been identified to display insecure attachment. However, it is not clear which attachment dimension contributes more to high psychopathic traits, and more specifically to callous-unemotional (CU) traits, which parental relationship is more influential and if this differs across gender. This study examined the associations of adult attachment dimensions (avoidance and anxiety) and parental factors (regard, responsibility and control) with CU traits (N = 1149) using Hierarchical Linear Regression. The relationship with both parents was assessed separately to identify their unique contribution to CU traits in males and females respectively. The avoidant attachment positively predicted while the anxiety attachment dimension negatively predicted CU traits and this was the case for both male and female participants. Interestingly, maternal regard was a negative predictor of CU traits in males only, whereas paternal responsibility arose as a positive predictor of CU traits in females only. Attachment dimensions explained the largest variance in both males and females. Findings point to the importance of attachment dimensions contributing to CU traits even in an adult sample. Parental variables were less influential on CU traits compared to attachment related variables and findings suggest that there are differences between males and females. These findings have important implications for gender differentiated attachment based interventions for individuals with CU traits.

Pursuing the developmental aims of the triarchic model of psychopathy: Creation and validation of triarchic scales for use in the USC: RFAB longitudinal twin project

The triarchic model was advanced as an integrative, trait-based framework for investigating psychopathy using different assessment methods and across developmental periods. Recent research has shown that the triarchic traits of boldness, meanness, and disinhibition can be operationalized effectively in youth, but longitudinal research is needed to realize the model's potential to advance developmental understanding of psychopathy. We report on the creation and validation of scale measures of the triarchic traits using questionnaire items available in the University of Southern California Risk Factors for Antisocial Behavior (RFAB) project, a large-scale longitudinal study of the development of antisocial behavior that includes measures from multiple modalities (self-report, informant rating, clinical-diagnostic, task-behavioral, physiological). Using a construct-rating and psychometric refinement approach, we developed triarchic scales that showed acceptable reliability, expected intercorrelations, and good temporal stability. The scales showed theory-consistent relations with external criteria including measures of psychopathy, internalizing/externalizing psychopathology, antisocial behavior, and substance use. Findings demonstrate the viability of measuring triarchic traits in the RFAB sample, extend the known nomological network of these traits into the developmental realm, and provide a foundation for follow-up studies examining the etiology of psychopathic traits and their relations with multimodal measures of cognitive-affective function and proneness to clinical problems.

Sensation seeking and its relationship with psychopathic traits, impulsivity and aggression: a validation of the Dutch Brief Sensation Seeking Scale (BSSS)

Sensation seeking is a personality trait that manifests as a preference for change, variety and novelty. Sensation seeking has been positively associated with different externalising behaviours. However, its associations with psychopathic traits, impulsivity and aggression are unclear. These associations were examined via the psychometric properties of the Dutch version of the Brief Sensation Seeking Scale (BSSS) using individuals from the general population and forensic patients. The results show that the BSSS has good psychometric properties, including test-retest reliability and a four-factor structure. Additionally, the results support associations between sensation seeking and psychopathic traits, impulsivity and total scores of aggression but revealed no specific associations with different types of aggression (e.g. proactive and reactive). The Dutch BSSS is a valuable tool for assessing sensation seeking in both the general population and forensic patients. Future research should further examine its utility and explore the role of sensation seeking in antisocial conduct.

In the eyes of the beholder: investigating the effect of visual probing on accuracy and gaze fixations when attending to facial expressions among primary and secondary callous-unemotional variants

Individuals with callous-unemotional (CU) traits show deficits in facial emotion recognition. According to preliminary research, this impairment may be due to attentional neglect to peoples' eyes when evaluating emotionally expressive faces. However, it is unknown whether this atypical processing pattern is unique to established variants of CU traits or modifiable with intervention. This study examined facial affect recognition and gaze patterns among individuals (N = 80; M age = 19.95, SD = 1.01 years; 50% female) with primary vs secondary CU variants. These groups were identified based on repeated measurements of conduct problems, CU traits, and anxiety assessed in adolescence and adulthood. Accuracy and number of fixations on areas of interest (forehead, eyes, and mouth) while viewing six dynamic emotions were assessed. A visual probe was used to direct attention to various parts of the face. Individuals with primary and secondary CU traits were less accurate than controls in recognizing facial expressions across all emotions. Those identified in the low-anxious primary-CU group showed reduced overall fixations to fearful and painful facial expressions compared to those in the high-anxious secondary-CU group. This difference was not specific to a region of the face (i.e. eyes or mouth). Findings point to the importance of investigating both accuracy and eye gaze fixations, since individuals in the primary and secondary groups were only differentiated in the way they attended to specific facial expression. These findings have implications for differentiated interventions focused on improving facial emotion recognition with regard to attending and correctly identifying emotions.

Triarchic Neurobehavioral Correlates of Psychopathology in Young Children: Evidence from the Healthy Brain Network Initiative

Recent initiatives emphasize the need to consider developmental and transdiagnostic contributions of temperamental variation to psychopathological expression. Triarchic neurobehavioral trait dimensions (boldness, meanness, disinhibition), which demonstrate compatibility with established temperament models and can be quantified using items from different existing inventories, are well-suited to pursuing these goals. We undertook to develop item-based scales for indexing these traits in 285 children (ages 5-10) tested in the Child Mind Institute's Healthy Brain Network (HBN) study, and evaluated their psychometric properties in two separate samples of similar-aged children: 519 others from the HBN study and 261 for whom parental-informant ratings were obtained through MTurk. Associations with psychopathology measures provided evidence for a) transdiagnostic utility of the triarchic scales, b) (reversed) boldness as the strongest predictor of internalizing problems, c) meanness as related to both internalizing and externalizing problems, d) disinhibition as the strongest predictor of externalizing problems, and e)a moderating effect of meanness level on disinhibition's relationship with externalizing problems. This research demonstrates that the triarchic traits can be effectively represented in young children and show expected relations with clinical outcome measures. As such, this work provides a foundation for developmental research clarifying the role that core neurobehavioral dispositions play in mental health.

Social Problems in Children: Exploring the Contribution of Triarchic Traits and Parenting

Social problems are transdiagnostically relevant in the development of various forms of psychopathology. It is thus important to consider contributing factors both at the individual and contextual level. Among 110 children (M_age = 8.85 years), we examined the contribution of triarchic trait dimensions (boldness, meanness, disinhibition) and parenting to the explanation of social problems. Using existing parent-report scales, triarchic scale-level representations were developed and validated. Significant main effects emerged for all three trait dimensions; meanness and disinhibition positively, boldness negatively, associated with social problems. Higher levels of disinhibition and meanness were associated with increased social problems in the context of higher levels of negative, or decreased levels of positive parenting; boldness acted as a protective factor in these contexts. Results suggest that the triarchic trait dimensions (1) can be studied in children, (2) act as risk and protective factors, and (3) interact with parenting to contribute to social problems.

The Abbreviated Psychopathy Measure-2: associations with normal-range and maladaptive personality traits

Background

The aim of the study was to validate an updated form of the Abbreviated Psychopathy Measure which is based on the triarchic model of psychopathy. Revisions were made to improve indexing of the triarchic scales. The study focused on examining the relationships between the APM-2 scales with lower-order personality traits associated with psychopathy, as well as with antiso-cial intent, a correlate of antisocial behavior.

Participants and procedure

A convenience sample of participants (N = 190) was recruited from Amazon’s Mechanical Turk (MTurk). Construct validity of the APM-2 scales was examined using Pearson’s r correlation and multiple regression analyses to determine the relationships between APM-2 scales and criterion measures.

Results

The APM-2 Total score was associated at moderate to high levels with core personality features associated with psychopathy. APM-2 Boldness was associated with both positive adjustment (social potency, emotional stability), and negative adjustment (both dangerous and calculated sensation seeking). APM-2 Meanness was associated with measures of callousness, hostile aggression, and manipulativeness, as well as with a measure of antisocial intent. APM-2 Disinhibition was associated with measures of impulsive, norm violating behavior, negative emotional disposition, and antisocial intent.

Conclusions

The associations between APM-2 scales and personality traits replicated certain key findings reported in the literature regarding psychopathy-relevant traits indexed by the Triarchic Psychopathy Measure (TriPM). Thus, this study provides a preliminary indication, albeit with a limited range of personality and antisocial behavior variables, that the nomological networks of the APM-2 scales may parallel the nomological networks of the TriPM scales.

Affective startle modulation and psychopathology: Implications for appetitive and defensive brain systems

Startle reflex potentiation versus startle attenuation to unpleasant versus pleasant stimuli likely reflect priming of the defensive versus appetitive motivational systems, respectively. This review summarizes and systemizes the literature on affective startle modulation related to psychopathologies with the aim to reveal underlying mechanisms across psychopathologies. We found evidence for psychopathologies characterized by increased startle potentiation to unpleasant stimuli (anxiety disorders), decreased startle potentiation to unpleasant stimuli (psychopathy), decreased startle attenuation to pleasant stimuli (ADHD), as well as a general hyporeactivity to affective stimuli (depression). Increased versus decreased startle responses to disorder-specific stimuli characterize specific phobia and drug dependence. No psychopathology is characterized by increased startle attenuation to standard pleasant stimuli or a general hyperreactivity to affective stimuli. This review indicates that the defensive and the appetitive systems operate independently mostly in accordance with the motivational priming hypothesis and that affective startle modulation is a highly valuable paradigm to unraveling dysfunctions of the defensive and appetitive systems in psychopathologies as requested by the Research Domain Criteria initiative.

Disinhibition as a unifying construct in understanding how personality dispositions undergird psychopathology

Disinhibition has been a construct of interest for decades, as evidenced by its inclusion in most prominent models of general personality functioning and its link to personality pathology, other psychopathology, health behaviors, and public health concerns. Disinhibition is manifest in behavioral, task based, and physiological measures, and common etiologies are a major reason for the coherence of the domain across a variety of assessment modalities. The current review will provide a summary of the conceptualization of the construct across prominent models, its link to psychopathology and maladaptive behaviors, and its etiology. Finally, we provide discussion on its clinical application utilizing disinhibition to aid in understanding comorbid psychopathology and through a description of its potential use in treatment.

N2 amplitude modulation across the antisocial spectrum: a meta-analysis

Despite the accumulated knowledge on antisocial behavior and the positive event-related potential peaking around 300 ms (P3), less is known about the preceding negative electrophysiological response around 200 ms (N2). A systematic search of the literature was conducted to analyze the N2 modulation across the antisocial spectrum. Thirty-seven studies (n = 1199) were retrieved to the quantitative analysis. Reduced N2 amplitudes were found in the more severe antisocial manifestations (violent behavior and antisocial personality disorder), which is consistent with previous findings on P3 alterations and N2 reduced amplitudes in externalizing disorders. Findings on psychopathy were mixed, also in accordance with previous P3 results. From a dimensional lens, this supports the heterogeneity of the psychopathic personality structure: impulsivity features are a closer attribute of antisocial behavior and thus may be associated with N2 reduction, while adaptive psychopathic traits may be associated with intact (or even increased) N2 amplitude. The increased N2 amplitudes observed in impulsive behavior challenge, however, the previous meta-analytic findings. As most of the studies on impulsivity include subclinical samples, it leads to the hypothesis that some compensatory mechanisms can still occur at a subclinical level, reflecting the need for heightened allocation of brain resources to yield similar performances. Importantly, inhibition was the core deficit to explain N2 blunted amplitudes, alongside with deficits in the frontal brain region. From our findings, the reduction in P3 amplitude across the antisocial spectrum may be detected in the previous N2 time window.

Not Just for Adults: Using the Triarchic Model of Psychopathy to Inform Developmental Models of Conduct Problems in Adolescence

The triarchic model of psychopathy was advanced to reconcile differing historic conceptions of this condition and alternative approaches for assessing it. The current study was undertaken to expand the empirical evidence base for the triarchic model by examining its correlates in adolescents, with measures of particular relevance to developmental theories of antisocial behavior. Self-report scales assessing the triarchic constructs were administered along with measures of conduct problems, callous-unemotional traits, attachment style dimensions, negative emotionality, and hyperactivity/inattention to 608 Italian adolescents (272 girls; M age = 16.70 years). The disinhibition dimension of the triarchic model was related most highly to general externalizing outcomes, such as conduct problems and hyperactivity-inattention, in this adolescent sample. The meanness dimension was selectively related to callous-unemotional traits and other measures of limited prosocial emotions and to affiliation motives that emphasize social gain. Triarchic boldness was associated with greater emotional stability and greater confidence in peer relationships. Of interest, an interaction between meanness and boldness was evident in predicting a lower need to understand one's own and others' emotions. These results provide a valuable illustration of the potential of the triarchic model to help advance developmental models of antisocial behavior in youth. Public Significance Statement This study examined how dimensions of psychopathy described by the triarchic model relate to measures of problem behaviors and affective-interpersonal style in an adolescent sample. Scores on the three triarchic dimensions-disinhibition, meanness, and boldness-showed meaningful contrasting relations with conduct problems, hyperactivity/inattention, callous-unemotional traits, emotional proclivities, and attachment style dimensions. This work illustrates how the triarchic model conceptualization can help advance developmental models of the emergence of antisocial behavior.

Adolescent psychopathy, heart rate, and skin conductance

Researchers have advocated for a greater focus on measuring neurobiological underpinnings of serious psychological conditions such as psychopathy. This has become particularly important to investigate early in the life span, when intervention efforts for psychopathy-related behavior like conduct disorder (CD) are more successful. Given that psychopathy is a complex syndrome, it is also important to investigate physiological processes at a dimensional level. Using a sample of 56 adolescent male offenders (M_age = 15.92; SD = 1.31), this study explored the relationship between the Psychopathy Checklist-Youth Version (Forth, Kosson, & Hare, 2003), heart rate (HR), and skin conductance (SC). A white noise countdown task was used to measure autonomic activity across a baseline, anticipatory (prenoise), and reactivity (postnoise) period. Findings revealed no significant associations between psychopathy and HR activity across the time intervals. However, results revealed a positive association between grandiose-manipulative traits and SC activity and a negative association between callous-unemotional traits and SC activity. The results indicate that autonomic processes may contribute to distinct psychopathic traits in different ways, implicating slightly differential brain functioning. The findings suggest that, in order to better understand and treat youth with CD, future research should continue to examine the biological correlates of psychopathy at the broader construct level but perhaps especially at the component level.

An Examination of Triarchic Psychopathy Constructs in Female Offenders

This study sought to expand scientific knowledge on psychopathic personality traits in female offenders by evaluating the relationship between MMPI-2-RF triarchic scales and self-reported external variables in a sample of 205 female offenders. Results indicated that boldness was inversely related to internalizing dysfunction, including suicidal behavior, psychosis, youth conduct problems, problems stemming from alcohol use, and a history of outpatient mental health treatment. Meanness was positively related to internalizing dysfunction as well as youth conduct problems, anger, prison disciplinary reports, and psychosis. Disinhibition was associated with a history of abuse in childhood, suicidal behavior, internalizing dysfunction, problems associated with alcohol and drug use, family history of mental illness, prison disciplinary reports for violence, number of previous criminal charges, and anger. Consistent with views of psychopathy as a configural condition, interactive effects of boldness with disinhibition and meanness were observed for multiple key external variables (e.g., conduct problems, substance use, nonsuicidal self-injurious behavior). This study provides further evidence for the triarchic conceptualization of psychopathy in female offenders and lends additional support for the validity of MMPI-2-RF triarchic psychopathy scales.

Psychopathic personality traits as a form of dispositional capability for suicide

The capability to enact lethal self-harm has recently been highlighted as a critical risk factor for suicidal behavior. Klonsky and May's (2015) three step theory of suicide (3ST) expanded upon the construct of the capability for suicide by dividing it into categories: dispositional, acquired, and practical. The current study examined constructs of Patrick and colleagues' (2009) triarchic model of psychopathy as indicators of dispositional capability in gun owners, a sample at heightened risk for death by suicide (Anestis and Houtsma, 2017). We anticipated that specific psychopathic traits would exhibit robust associations with other components of the capability for suicide. In a sample of 300 gun-owning adults, Boldness was uniquely related to all indicators of practical capability in both male and female gun owners, and a Boldness*Meanness interaction predicted the highest levels of some capability components. These results are consistent with theoretical conceptualizations of the triarchic model. Our findings indicate that, among US gun owners, dispositional factors may impact comfort with and aptitude with guns, which may enhance our understanding of which gun owners are at the greatest risk of gun suicide should they develop suicidal thoughts.

Dimensions of youth psychopathy differentially predict concurrent pro- and antisocial behavior

Objective:

To investigate the unique contribution of narcissism and impulsivity, in addition to callous-unemotional (CU) traits, in explaining concurrent prosocial and antisocial behavior.

Method:

Two hundred and forty-nine schoolchildren (53% female; age 9-12 years) completed the self-report Strengths and Difficulties Questionnaire (SDQ) and the Antisocial Process Screening Device (APSD). Two statistical models were tested, predicting conduct problems (CP) and prosocial behavior (PB). In the first one, CU traits and gender were entered into the equation. The second model added narcissism and impulsivity.

Results:

Gender, narcissism and impulsivity, but not CU, were statistically significant predictors of CP in the second model (F_3,226 = 45.07, p < 0.001, R² = 43.7%; betas: gender = -0.20, narcissism = 0.29, impulsivity = 0.36, CU = 0.06). PB was significantly predicted by all domains except gender (F_3,226 = 42.57, p < 0.001, R² = 42.4%; betas: gender = 0.08, narcissism = -0.16, impulsivity = -0.23, CU = -0.41).

Conclusion:

Our results confirmed that CU traits refer to a distinct manifestation of psychopathy in youth, but we also found that narcissism and impulsivity are equally important when predicting CP. Previous reports of sex differences on APSD and SDQ domains were also corroborated.

Studying Delusions Within Research Domain Criteria: The Challenge of Configural Traits When Building a Mechanistic Foundation for Abnormal Beliefs

Our understanding of belief formation, maintenance, and change is in its infancy, yet it is absolutely essential to make progress in understanding these processes to parse the puzzle of psychotic delusions. In this companion to Bebbington and Freeman, I consider a number of Research Domain Criteria constructs that may be helpful for exploring these processes but ultimately conclude (following Risen) that delusions are likely the result of several systems failing. I close with 4 recommendations for making progress: (1) prepare to study a variable space defined by several relevant constructs, (2) include the study of "unsanctioned" constructs, (3) examine the relationships between brain regions, rather than the local abnormalities, and (4) develop rigorous computational models of delusions.
