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.

Individuals with antisocial personality disorder (ASPD) are characterized by impulsive behavior and a lack of empathy, which can eventually lead to criminal behavior. In our narrative review, we are investigating the neurological differences in the function, structure, and connectivity of those with ASPD in comparison to those without, with a major focus on psychopathic cluster B populations of ASPD individuals. We reviewed 86 published articles, and five of these met the inclusion criteria for distinct psychopathic and non-psychopathic groups. After reviewing these sources, we found deficits in function and structure leading to a lack of empathy and adherence to social norms in individuals with ASPD. Currently, there are very few treatment options for those living with ASPD. It is our opinion that with a better understanding of the structural and functional differences in those with ASPD, we might see more efficacious treatment therapies for this population group in the medical community.

UNASSIGNED: The aim of this systematic review was to synthesise research examining the relationship between autism and psychopathy to: (a) better understand the relationship between these two constructs, and (b) describe the clinical manifestation of the two when they co-occur. A systematic search of the literature returned 36 studies.
UNASSIGNED: Across all ages, autistic individuals and those with elevated autistic traits but no autistic diagnoses appeared to have increased callous and unemotional traits or psychopathy relative to the general population. Several studies evidenced that although both constructs are associated with empathetic dysfunction, the underlying mechanisms differ. In adults, psychopathy/psychopathic traits were associated with diminished affective empathy and intact cognitive empathy, whilst the opposite was seen autistic adults and those with elevated autistic traits. In children, those with autistic traits or a diagnosis of autism had diminished cognitive empathy, but not affective empathy, while the relationship between callous and unemotional traits/psychopathy and empathy amongst children was less clear. The co-occurrence of autism and psychopathy was seen to lead to additional empathic and cognitive impairment, but findings were mixed making it challenging to clearly describe the clinical manifestation.
UNASSIGNED: There remains a paucity of research investigating the interaction between autism and psychopathy and included studies were characterised by multiple measurement difficulties. Attention should be directed toward developing better methods for identifying psychopathic traits in autistic individuals to advance our understanding of the relationship between autism and psychopathy to allow for the development of appropriate care pathways for this population.

Nowadays it is important for companies to keep their profits and productivity high. This can be achieved by creating a good environment in which employees can perform at their best. Unfortunately, counterproductive work behavior (CWB) is widespread in the workplace and poses a serious threat to both organizational performance and employee well-being. Among the many potential risk factors for CWB, the Dark Triad (DT) personality traits (Machiavellianism, narcissism, and psychopathy) have received increasing attention in recent years. To assess the robustness and magnitude of the association between DT and CWB, we conducted a systematic review of the available literature on DT and CWB using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines after a thorough search of several databases, 21 papers were included. The results showed that DT and CWB are positively associated. Psychopathy exhibited the strongest positive association with CWB, followed immediately by Machiavellianism and narcissism. Moreover, Machiavellianism and psychopathy showed positive correlations with both forms of CWB (organisational and interpersonal), whereas narcissism was positively correlated only with interpersonal CWB. Our findings highlight that even though organisations could benefit from people with DT at the performance level, there could be serious implications for well-being and an appropriate work environment due to CWB.

There has been a growing interest around the broader effects of psychopathic traits, particularly in relation to deviant behaviors and the notion of so-called \"successful psychopathy\". As significant sociocultural touchstones, sporting events are often characterized by competitiveness and a sense of prestige. However, there has been limited attention towards psychopathic traits across recreational, amateur, and elite sports. Accordingly, we conducted a narrative review synthesizing primary observations on this topic, searching keywords in Scopus, APA PsychNet, and PubMed. Twenty-four academic papers were included in our results, which we thematized around demographic groups, namely: athletes and sport-adjacent non-athletes (i.e., coaches and spectators). Based on empirical findings from the reviewed papers, psychopathic traits could have medicolegal and forensic implications in relation to substance use, aggression, and violence. These could intersect with wider issues around doping, cheating, foul play, and have adverse outcomes for fellow participants, team dynamics, and spectators. Interestingly, our review also indicates that psychopathic traits may have correlations with determination and achievement in sport, echoing developing ideas around \"successful psychopathy\" in other domains. As such, increased awareness from all stakeholders and further multidisciplinary exchanges are vital to better understand the effects of psychopathic traits in sporting frameworks and their wider consequences.

This literature review aims to analyze studies published by researchers on the topic of the relationship between the psychological constructs of the Dark Triad and Cognitive Empathy. This study hypothesizes how having good cognitive empathic skills could benefit people who demonstrate Dark Triad traits, as this could facilitate the implementation of manipulative strategies. Through the process of identifying studies via databases and registers, 23 studies were included in this literature review, and the results and theories brought forward by the researchers find more agreement regarding the individual components of the Dark Triad than the whole construct: narcissism seems to have, for the most part, relatively small and typical positive correlations (more than 50% of correlations), Machiavellianism has relatively small and typical negative relationships (about 80% of correlations), and psychopathy has relatively large negative relationships (about 90% of correlations). This study conveys that Machiavellians and psychopaths, having reduced empathic abilities, use manipulation techniques that do not have to do with empathy (for example seduction, intimidation etc.), while narcissists would be, among these three dimensions, those most likely to understand others\' states of mind and thus be able to use this knowledge to their advantage-although there are doubts about the veracity of the statements and answers given by narcissists in the tests administered to them. This literature review could be a valid aid to professionals dealing with people who exhibit Dark Triad traits; understanding how those exhibiting Dark Triad traits manage their empathic abilities, the areas in which the various dimensions show deficits or not, and how they act to implement their manipulative and controlling tactics could aid in the development of more effective helping strategies to be utilized in therapy settings.

The CNV is analyzed in tasks related to EEG studies, often with participants presenting psychopathic personality traits. A systematic search of the literature was conducted, to solve some inconsistencies regarding CNV amplitude modulation by psychopathy. Nine studies (N = 317) were retrieved for analysis. Three meta-analyses were run - CNV, iCNV, tCNV. A qualitative analysis - reporting CNV amplitudes modulated by psychopathy dimensional features - was also featured. Overall effects for CNV and iCNV were not significant. Larger tCNV amplitudes were found in participants reporting higher psychopathy traits, g = -0.58, 95% CI [- 0.94, - 0.22]. These findings were surprising when confronted with previous assumptions in the literature, especially considering that no significant heterogeneity between studies was found. Neither of the studies\' characteristics was a significant moderator. Findings require the need to discuss key differences between adaptive/(mal)adjustment patterns in participants presenting psychopathic traits. Future studies dissociating iCNV and tCNV modulation by psychopathy, especially in community samples and through a dimensional lens, could help to better understand the construct of psychopathy.

Psychopathy encompasses a constellation of personality traits, including interpersonal callousness, absence of remorse and guilt, and impulsivity. While extensive research has linked psychopathy to various antisocial behaviours, there has been a scarcity of studies investigating its association with prosocial behaviours, particularly within diverse sociocultural contexts. This comprehensive review explores recent literature that delves into the intricate interplay between psychopathy, prosocial behaviours, and self-construal. The current review reveals a complex and sometimes contradictory relationship between psychopathy and prosocial behaviours. The authors also examine the role of self-construal, a crucial sociocultural aspect, in relation to psychopathy and prosocial behaviours, and imply the intricate interplay between them. Amidst the review, the interactions between key constructs and sociocultural as well as contextual factors, including group identification and public awareness, are highlighted, and their potential role in modulating individuals\' prosocial decision-making is discussed. At last, this review pinpointed notable research gaps: the potential moderating role of self-construal in the connection between psychopathy and prosocial behaviours, and a methodologically specific recommendation for future research is proposed. These findings consolidate the current evidence on psychopathy, self-construal and prosocial behaviours, and offer valuable insights into how sociocultural factors contribute to the heterogeneous expression of psychopathic traits, illuminating the directions for research on the development of culture-specific conceptualizations of psychopathy.

Psychopathy has been empirically associated with various forms of antisocial behavior including sexual assault. In fact, the lack of empathy characterizing psychopathic offenders may facilitate the perpetration of more extreme violence. This systematic review aims to explore the relationship between psychopathy traits in male adult sex offenders and the increase in recidivism risk for any type of reoffence, with a special focus on sexual recidivism. From an initial sample of 757 articles related to the topic, only 14 were selected from the current literature at the end of the inclusion process. Each of these assessed the relation between psychopathy traits (measured by PCL-R) and recidivism risk in male sex offenders (age > 18), providing an effect size (quantitative findings). The results of their analysis agree with the currently available literature: the presence of psychopathic traits in sex offenders would seem to correlate with an increased risk of recidivism of general but non-sexual. Furthermore, almost half of the included works highlighted a positive relationship between psychopathy and violent reoffences. However, the limited availability of studies and the unevenness in their results indicate the need to expand future research in this direction.

This meta-analysis aims to examine the relationship between psychopathic traits and theory of mind (ToM), which is classically and broadly defined as competency in representing and attributing mental states such as emotions, intentions, and beliefs to others. Our search strategy gathered 142 effect sizes from 42 studies, with a total sample size of 7463 participants. Random effects models were used to analyze the data. Our findings suggested that psychopathic traits are associated with impaired ToM task performance. This relationship was not moderated by factors such as age, population, psychopathy measurement (self-report versus clinical checklist) or conceptualization, or ToM task type (cognitive versus affective). The effect also remained significant after excluding tasks that did not require the participant to 1) mentalize or 2) differentiate between self and other perspectives. However, interpersonal/affective traits were associated with a more pronounced impairment in ToM task performance compared to lifestyle/antisocial traits. Future research should investigate the effects of distinct psychopathy facets that will allow for a more precise understanding of the social-cognitive bases of relevant clinical presentations in psychopathy.
