Investigators commonly distinguish between primary and secondary psychopathy (H. Cleckley, 1976; D.T. Lykken, 1995), though there is a lack of consensus regarding the best means to achieve this distinction. To address validity using R. D. Hare's (2003) Psychopathy Checklist G. Welsh (1956) Anxiety Scale for purpose, authors used 2 measures J. A. Gray's (1987) behavioral inhibition system/behavioral activation system (BIS/BAS). Following T. Lykken (1995) C. Fowles (1980), hypothesized that...
Although prior research has examined the genetic correlates of antisocial behavior, molecular genetics influences on psychopathic traits remain largely unknown. Consequently, we investigated influence polymorphic variation at serotonin transporter protein gene (SLC6A4) and socioeconomic resources (SES) in youth across two distinct samples separate studies. In Study 1, a main effect (5-HTTLPR) genotype was associated with impulsivity dimension psychopathy. That is, individuals homozygous for...
The field of personality disorders has had a long-standing interest in understanding interactions between emotion and inhibitory control, as well neurophysiological indices these processes. More work particular is needed to clarify differential deficits offenders with antisocial disorder (APD) who differ on psychopathic traits, APD psychopathy are considered separate, albeit related, syndromes. Evidence distinct neurobiological processing would have implications for etiology-based taxonomies...
Moderate-to-severe traumatic brain injury is one of the strongest environmental risk factors for development neurodegenerative diseases such as late-onset Alzheimer's disease, although it unclear whether mild injury, or concussion, also confers risk. This study examined and genetic predictors reduced cortical thickness in regions previously associated with early their relationship episodic memory. Participants were 160 Iraq Afghanistan War veterans between ages 19 58, many whom carried...
The current study investigated how mechanisms of attention that have been well-characterized in the cognitive psychology literature (Lavie, Hirst, De Fockert, & Viding, 2004; Maylor Lavie, 1998) may be differentially associated with psychopathic traits nonincarcerated men. Previous research on cognition and psychopathy indicated primary were overfocused and/or reduced processing information peripheral to focus attention. Conversely, deficits executive functioning, such as working memory...
Evidence suggests that the combination of interpersonal-affective (F1) and impulsive-antisocial (F2) features psychopathy may be associated with borderline personality disorder (BPD), specifically among women (e.g., Coid, 1993; Hicks, Vaidyanathan, & Patrick, 2010). However, empirical research explicitly examining gendered relationships between BPD factors is lacking. To further inform this area research, we investigated hypothesis interplay two across studies. Study 1 consisted a college...
Risky behaviors increase the likelihood of premature death, long-term disability, and poor mental health outcomes. Most current measures risky behavior only assess within a single domain, fail to evaluate affective triggers for engaging in these behaviors, do not index consequences are often limited narrow developmental period. The present study developed evaluated new 38-item questionnaire-based measure, Risky, Impulsive, Self-Destructive Behavior Questionnaire (RISQ), designed address each...
Little research has examined different dimensions of narcissism that may parallel psychopathy facets in criminally involved individuals. In this study, we the pattern relationships between grandiose and vulnerable narcissism, assessed using Narcissistic Personality Inventory-16 Hypersensitive Narcissism Scale, respectively, four (interpersonal, affective, lifestyle, antisocial) via Psychopathy Checklist: Screening Version. As predicted, showed differential to facets, with relating positively...
Background DNA methylation of the SKA2 gene has recently been implicated as a biomarker suicide risk and posttraumatic stress disorder (PTSD). To examine specificity reliability these findings, we examined associations between methylation, broad dimensions psychiatric symptoms, phenotypes in adults with high levels trauma exposure. Methods A total 466 White, non-Hispanic veterans their intimate partners (65% male) underwent clinical assessment had blood drawn for genotyping analysis. CpG...
A large body of research has examined relationships between distal experiences victimization and the likelihood engaging in violence later life. Less is known about influence recent violent on risk for perpetration. To our knowledge, this first study to examine prospectively whether adulthood increases future violence. Specifically, present assessed incremental validity prediction a sample justice-involved adults with serious mental illness. The (a) (i.e., within 6 months baseline...
Posttraumatic stress disorder (PTSD) is a potentially important, yet understudied, mental to consider in models of criminal recidivism. The present study sought address this gap the literature with large-scale secondary analysis observational data from sample justice-involved persons disorders. Administrative were reviewed for 771 adult jail detainees Hierarchical logistic regression showed that PTSD was associated greater likelihood general (arrest any new charge) and serious felony...
The fifth edition of the Diagnostic and Statistical Manual includes a dissociative subtype posttraumatic stress disorder, but no existing measures specifically assess it. This article describes initial evaluation 15-item self-report measure called Dissociative Subtype Posttraumatic Stress Disorder Scale (DSPS) in an online survey 697 trauma-exposed military veterans representative U.S. veteran population. Exploratory factor analyses lifetime DSPS items supported intended structure consisting...
Recently developed indices of cellular age based on DNA methylation (DNAm) data, referred to as DNAm age, are being used study factors that influence the rate aging and health correlates these metrics epigenetic clock. This evaluated associations between trauma exposure, posttraumatic stress disorder (PTSD) symptoms, accelerated versus decelerated among military veterans. We also examined whether predicted mortality over course a 6.5-year medical record review period.
Impersonal stressors, not only interpersonal provocation, can instigate aggression through an associative network linking negative emotions to behavioral activation (L. Berkowitz, 1990). Research has examined the brain mechanisms that are engaged by different types of stress and serve promote hostility aggression. The present study whether exposure elicits more left than right frontal activity implicated in approach motivation this lateralized predicts stress-induced hostile/aggressive...
Suicidality represents one of the most important areas risk for adolescents, with both internalizing (e.g., depression, anxiety) and externalizing-antisocial substance use, conduct) disorders conferring suicidal ideation attempts Bridge, Goldstein, & Brent, 2006). However, no study has attended to gender differences in relationships between suicidality different facets psychopathic tendencies youth. Further, very little research focused on disentangling multiple manifestations suicide same...
Objective: Although many mental health courts (MHCs) have been established to reduce criminal justice involvement of persons with disorders, research has not kept pace the widespread implementation these courts. Whereas early MHCs were restricted charged nonviolent misdemeanors, now accept more serious charges for whom ameliorating risk violence is a greater concern. This study evaluated relationship between MHC participation and by using prospective design. It was hypothesized that would...
Deficits in impulse control are increasingly recognized association with posttraumatic stress disorder (PTSD). To our further understanding of the neurobiology PTSD-related disinhibition, we examined alterations brain morphology and network connectivity associated response inhibition failures PTSD severity. The sample consisted 189 trauma-exposed Operation Enduring Freedom/Operation Iraqi Freedom veterans (89% male, ages 19-62) presenting a range current Disinhibition was measured using...
ABSTRACT Converging lines of research indicate that inhibitory control is likely to be compromised in contexts place competing demands on emotional, motivational, and cognitive systems, potentially leading damaging impulsive behavior. The objective this study was identify the neural impact three challenging typically compromise self‐regulation weaken impulse control. Participants included 66 healthy adults ( M / SD age = 29.82/10.21 years old, 63.6% female) who were free psychiatric...
