The current study investigated the relationship between psychopathy and two concepts that hold a central position in conceptualizations of this disorder, being guilt and dominance. Both constructs were measured using explicit measures (i.e., self-report), as well as indirect assessment (i.e., the Single Category Implicit Association Test; Sc-IAT). Our sample consisted of 43 psychopathic offenders, 42 nonpsychopathic offenders, and 26 nonoffender controls. Although no overall group differences emerged, the lifestyle/antisocial traits of psychopathy (Factor 2) predicted reduced self-reported guilt on a dimensional level...

We report on the psychometric properties of the Mental Health and Social Inadaptation Assessment for Adolescents (MIA), a self-report instrument for quantifying the frequency of mental health and psychosocial adaptation problems using a dimensional approach and based on the DSM-5. The instrument includes 113 questions, takes 20-25 minutes to answer, and covers the past 12 months. A population-based cohort of adolescents (n = 1443, age = 15 years; 48% males) rated the frequency at which they experienced symptoms of Attention Deficit Hyperactivity Disorder (ADHD), Conduct Disorder, Oppositional Defiant Disorder, Depression, Generalized Anxiety, Social Phobia, Eating Disorders (i...

This study investigated how well components of the psychopathy trait are measured among college students with the Levenson Self-Report Psychopathy Scale (LSRP), the Personality Assessment Inventory-Antisocial Features Scale (PAI ANT), the Psychopathic Personality Inventory-Short Form (PPI-SF), and the Self-Report Psychopathy Scale-II (SRP-II). Using Samejima (1969)'s graded response model (GRM), the subscales were found to vary in their ability to measure the corresponding latent traits. The LSRP primary psychopathy factor is more precise in measuring the latent trait than the secondary psychopathy factor...

The relevance of boldness to psychopathy has recently become a major flashpoint of scientific controversy. Although some authors have contended that boldness is a necessary (although insufficient) component of psychopathy, others have asserted that it is largely or entirely irrelevant to psychopathy. We addressed this issue by examining clinical perceptions of the relevance of the 3 triarchic dimensions (boldness, disinhibition, and meanness) to psychopathy among a sample of mental health professionals and graduate students (N = 228) using a vignette-based, person-centered methodology...

The current study employed both latent variable- and person-centered approaches to examine psychopathic traits in a large sample of sex offenders (N = 958). The offenders, who had committed a range of sexual crimes, had been assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four-factor model of psychopathy (Hare, 2003; Neumann, Hare, & Newman, 2007) provided good representation of the dimensional nature of psychopathic traits across the sample of offenders, and that the PCL-R factors significantly predicted sexual crimes...

Psychopathy is a personality disorder characterized by callous lack of empathy, impulsive antisocial behavior, and criminal recidivism. Studies of brain structure and function in psychopathy have frequently identified abnormalities in the prefrontal cortex. However, findings have not yet converged to yield a clear relationship between specific subregions of prefrontal cortex and particular psychopathic traits. We performed a multimodal neuroimaging study of prefrontal cortex volume and functional connectivity in psychopathy, using a sample of adult male prison inmates (N=124)...

AIM: To clarify the differences in views on forensic mental health (FMH) systems between the United Kingdom and Japan. METHODS: We conducted a series of semi-structured interviews with six leading forensic psychiatrists. Based on a discussion by the research team, we created an interview form. After we finished conducting all the interviews, we qualitatively analyzed their content. RESULTS: In the United Kingdom the core domain of FMH was risk assessment and management; however, in Japan, the core domain of FMH was psychiatric testimony...

The current study examined the reliability and validity of the Youth Psychopathic Traits Inventory-Short Version (YPI-S) in two different samples of at-risk adolescents enrolled in a residential program ( n = 160) and at a detention facility ( n = 60) in the United States. YPI-S scores displayed adequate internal consistency and were moderately associated with concurrent scales on other self-report psychopathy measures and externalizing behaviors. YPI-S scores were moderately related to interviewer-ratings of the construct using the four-factor model of the Psychopathy Checklist: Youth Version...

In this paper it is proposed that important components of moral development and moral judgment rely on two forms of emotional learning: stimulus-reinforcement and response-outcome learning. Data in support of this position will be primarily drawn from work with individuals with the developmental condition of psychopathy as well as fMRI studies with healthy individuals. Individuals with psychopathy show impairment on moral judgment tasks and a pronounced increased risk for instrumental antisocial behavior. It will be argued that these impairments are developmental consequences of impaired stimulus-aversive conditioning on the basis of distress cue reinforcers and response-outcome learning in individuals with this disorder...

Although many adolescent risk assessment tools include an emphasis on dynamic factors, little research has examined the extent to which these tools are capable of measuring change. In this article, we outline a framework to evaluate a tool's capacity to measure change. This framework includes the following: (a) measurement error and reliable change, and (b) sensitivity (i.e., internal, external, and relative sensitivity). We then used this framework to evaluate the Structured Assessment of Violence Risk in Youth (SAVRY) and Youth Level of Service/Case Management Inventory (YLS/CMI)...

In the past decade, extensive interest has been directed toward the Dark Triad (i.e., Machiavellianism, narcissism, and psychopathy), popularly assessed by the Short Dark Triad (SD3). Nevertheless, relatively little research has been conducted on the SD3's factor structure. We investigated the SD3's psychometric properties in three studies with three independent samples, using exploratory and confirmatory factor analyses ( N1 = 1,487; N2 = 17,740; N3 = 496). In all three studies, Machiavellianism and psychopathy items displayed large general factor loadings, and narcissism larger specific factor loadings...

The notion that antisocial behavior reflects failures of empathy has a long history in the clinical literature, yet only recently has evidence emerged to support neuroscientific accounts of empathy and the development of child conduct problems. Much of this evidence has come from research into callous-unemotional traits, which correspond to the affective component of psychopathy and therefore encompass deficits in empathy within a broader cluster of emotional impairments. In this review we integrate current evidence concerning the biobehavioral bases of empathy and callous-unemotional traits, and discuss how it may inform models of heterogeneous subgroups of individuals with early onset conduct problems...

Researchers have recently questioned the utility of the response style indicators included on many self-report measures of personality and psychopathology. We examined whether the size of convergent validity coefficients for Personality Assessment Inventory (PAI) Antisocial Features (ANT) scores depends on PAI validity scale scores. Using PAI and Psychopathy Checklist-Revised (PCL-R) scores from 477 offenders evaluated for civil commitment as sexually violent predators, we found that PAI Positive Impression (PIM), Negative Impression (NIM), Malingering Index (MAL), Defensiveness Index (DEF), and Infrequency (INF) scores moderated the association between ANT and PCL-R scores...

Antisocial youth with callous-unemotional (CU) traits exhibit a pattern of severe and persistent conduct problems and deficits in emotional processing that parallels adults with psychopathy. Aberrant emotional attention, particularly among individuals high on aggression, constitutes one such deficit; however, its robustness across race/ethnicity requires further investigation given findings that the psychopathy construct manifests differently across race (Sullivan and Kosson 2006), and emotional attention is susceptible to the influence of adverse environmental factors such as violence exposure that is more common among ethnic minority youth (Kimonis et al...

There is a paucity of Indigenous-specific research examining the reliability and validity of assessment tools routinely utilized within the justice system. Evaluating the cross-cultural reliability and validity of such tools is important for establishing generalizability as part of ethical practices; this is particularly important to address within Canada's Indigenous youth population because of longstanding effects of colonization, structural adversities, and overrepresentation in the youth justice system and the possible long-term impact of improper assessment on adult outcomes...

BACKGROUND: Psychopathy is a mental health disorder characterized by callous and impulsive antisocial behavior, and is associated with a high incidence of violent crime, substance abuse, and recidivism. Recent studies suggest that the striatum may be a key component of the neurobiological basis for the disorder, though structural findings have been mixed and functional connectivity of the striatum in psychopathy has yet to be fully examined. METHODS: We performed a multimodal neuroimaging study of striatum volume and functional connectivity in psychopathy, using a large sample of adult male prison inmates (N=124)...

Neuroscience has identified brain structures and functions that correlate with psychopathic tendencies. Since psychopathic traits can be traced back to physical neural attributes, it has been argued that psychopaths are not truly responsible for their actions and therefore should not be blamed for their psychopathic behaviors. This experimental research aims to evaluate what effect communicating this theory of psychopathy has on the moral behavior of lay people. If psychopathy is blamed on the brain, people may feel less morally responsible for their own psychopathic tendencies and therefore may be more likely to display those tendencies...

The term dark triad refers to the constellation of narcissism, Machiavellianism, and psychopathy. Over the past few years, the concept has gained momentum, with many researchers assuming that the dark triad is a prominent antecedent of transgressive and norm-violating behavior. Our purpose in this meta-analytic review was to evaluate (a) interrelations among narcissism, Machiavellianism, and psychopathy; (b) gender differences in these traits; (c) how these traits are linked to normal personality factors; and (d) the psychosocial correlates of the dark triad...

REVIEW
Rita Pasion, Carina Fernandes, Mariana R Pereira, Fernando Barbosa
In 2009, Gao and Raine's meta-analysis analysed P3 modulation over the antisocial spectrum. However, some questions remained open regarding the P3 modulation patterns across impulsive and violent manifestations of antisocial behaviour, phenotypic components of psychopathy, and P3 components. A systematic review of 36 studies was conducted (N=3514) to extend previous results and to address these unresolved questions. A clear link between decreased P3 amplitude and antisocial behaviour was found. In psychopathy, dimensional approaches become more informative than taxonomic models...

In past years, research and corporate scandals have evidenced the destructive effects of the dark triad at work, consisting of narcissism (extreme self-centeredness), psychopathy (lack of empathy and remorse) and Machiavellianism (a sense of duplicity and manipulativeness). The dark triad dimensions have typically been conceptualized as stable personality traits, ignoring the accumulating evidence that momentary personality expressions - personality states - may change due to the characteristics of the situation...
