RESUMEN
The Comprehensive Assessment of Psychopathic Personality (CAPP) is a concept map developed to consolidate research on psychopathy. Recently, the CAPP - Self Report form (CAPP-SR) was developed, but its psychometric properties have not been extensively or independently investigated. The current study evaluated the internal consistency, factorial structure, and construct validity of the CAPP-SR in a large sample of undergraduate and community participants. No organizational structure was superior, but a theoretically supported three factor solution representing behavioral, affective, and interpersonal traits appeared to be the optimal solution. The CAPP-SR demonstrated overlap with other preexisting psychopathy measures and the three-factor solution evinced relatively good convergent and discriminant associations with external criteria. The CAPP-SR seems to measure a similar construct to psychopathy measures, though it remains unclear whether the new measure captures meaningful information neglected by other models or outperforms them in prediction of important outcomes.
RESUMEN
Only two studies to date have considered the joint effects of testosterone and cortisol on direct measures of criminal behavior. The current study extends this earlier work by incorporating the direct and interactive effects of baseline hormone measures and hormone change scores in response to social stress. The current study also extends prior work by considering distinct measures of different criminal behavior types and sex differences. Analyses based on a large sample of undergraduates indicated that testosterone had a positive and statistically significant association with impulsive and violent criminal behavior. The interaction of testosterone with cortisol had a negative association with income generating crime. Simple slopes analyses of this interaction indicated testosterone had a positive association with income generating crime when cortisol was low (-1 SD). Associations between hormones and criminal behavior were not moderated by sex.

This study investigated the ability of the Computerized Adaptive Test of Personality Disorder (CAT-PD) model to capture psychopathy in a sample consisting of U.S. (n = 565) and Australian (n = 99) undergraduates and a U.S. community sample (n = 210). More specifically, this study examined (a) the association between CAT-PD facets, particularly those consistent with DSM-5 Section III antisocial personality disorder (ASPD), and measures of psychopathy, (b) the extent to which CAT-PD ASPD traits improve on DSM-5 Section II ASPD in measuring psychopathy, and (c) the utility of measuring functional impairment in additional to dimensional traits in assessing psychopathy. Analyses revealed CAT-PD ASPD traits, including traits' associations with Section III psychopathy specifier, were strongly associated with measures of psychopathy. Furthermore, CAT-PD ASPD was found to be an improvement over DSM-5 Section II ASPD in measuring psychopathy, and the dimensional nature of the CAT-PD was found to render the addition of measures of impairment unnecessary. These findings generally support the utility of the CAT-PD in the measurement of psychopathy, particularly as it relates to the dimensional assessment of psychopathy in the DSM-5 alternative model for personality disorder.

An extensive line of research has found that children exposed to multiple forms of early life adversity are more likely to engage in high levels of delinquent behavior during adolescence. Several studies examining this association have used a range of multivariate statistical techniques capable of controlling for observable covariates. Fewer studies have used family-based research designs to additionally control for unobservable confounds, such as genetic and shared environmental influences, that may be associated with exposure to childhood adversity and delinquency. The current study analyzes self-report data on 2534 full-siblings (50% female) from the National Longitudinal Survey of Youth 1997 to conduct a sibling-comparison analysis to provide a rigorous test of the causal hypothesis that exposure to childhood adversity causes differences in developmental patterns of delinquent behavior. Results from multivariate latent growth curve models revealed that childhood adversity was associated with higher starting levels of delinquency during adolescence and slower rates of decline from adolescence to emerging adulthood. Results from multivariate sibling-comparison models, however, revealed that siblings exposed to higher levels of childhood adversity reported higher starting levels of delinquent behavior, but not slower declines over time, suggesting that childhood adversity may not be directly associated with long-term patterns of delinquent behavior after genetic and shared environmental factors are taken into account. Implications of these results for future research are discussed.

A substantial literature has investigated relations between intelligence and psychopathic traits. At the construct level, findings have been mixed, with a small negative relation found. At the facet level however, a positive relation between verbal intelligence and the interpersonal facet of psychopathy, and a negative relation between verbal intelligence and the lifestyle factor of psychopathy emerge. To date, this research has largely neglected adolescents and prior research has focused on clinical and incarcerated populations, while failing to control for psychopathology. The current study sought to address these limitations by examining the relation between intelligence and psychopathy at the construct, facet, and trait level in a sample of inpatient adolescents. At the bivariate level, verbal intelligence was related to dishonest charm, unemotionality, impulsiveness, and manipulation. In regression analyses, however, verbal intelligence lost significance as a predictor of all but impulsiveness. Gender and severity of psychopathology accounted for most significant relations.

A wealth of past research has examined the relationship between low physiological arousal and violence or antisocial behavior. Relatively little research; however, has examined the relationship between low physiological arousal and psychopathic traits, with even less having been conducted with juveniles. The current study attempts to fill this gap by evaluating juveniles' physiological arousal using resting heart rate and their levels of psychopathic traits. Results suggest that there is indeed an inverse relationship between resting heart rate and the affective traits of psychopathy (Uncaring, Callousness, and Unemotionality) as well as Thrill or Sensation Seeking in males. No significant relationship was found in females. Implications of the findings as well as study limitations and future directions are discussed.

The current study explored associations between testosterone, cortisol, and both the Levenson Self-Report Psychopathy Scale (LSRPS) and the Inventory of Callous Unemotional (ICU) traits. Data were gathered from a relatively large sample of university students (n = 522) and analyses considered direct and interactive associations between hormones and psychopathic traits, as well as interactions between these associations and the time of day at which samples were gathered and the sex of participants. Baseline cortisol had a negative association with LSRPS primary psychopathy scores. In addition, baseline cortisol interacted with the time of day in association with LSRPS total scores. Simple slopes analyses indicated cortisol had a negative association with LSRPS total scores in the morning but not the afternoon. Interactions among hormone measures were not statistically significant. There was also no evidence for the moderation of associations between hormones and psychopathic traits by sex.
RESUMEN
Rape myths are attitudes that implicitly and explicitly blame victims for their own sexual victimization. Greater adherence to rape myths is linked to several negative outcomes, including the neutralization of gender-based violence and the perpetration of sexual violence. Few studies have considered how previous life experiences and individual-level traits influence the development and greater adherence to rape myths. The current study examines how traits associated with the three-factor model of psychopathy (i.e., egocentric, callous, and antisocial dimensions) and adherence to traditional gender roles mediate the relationship between prior childhood/adolescent victimization and the acceptance of rape myths in a sample of college men and women (N = 789). Path modeling indicates that experiences of psychological victimization (before age 16) increased egocentric psychopathic traits, which then increased the acceptance of rape myths in men. In women, however, sexual victimization (before age 16) increased the acceptance of traditional gender roles, which then influenced the acceptance of rape myths. Additionally, the egocentric facet of psychopathy exerted indirect effects on the acceptance of rape myths through traditional views on gender roles in both men and women. These findings highlight the need to continue to examine egocentric personality traits in relation to the development of rape myths in adolescent and young adult populations. Directions for collegiate programming are discussed.

Despite early theorists suggesting that psychopathic traits are associated with higher intelligence, meta-analytic work has found that global psychopathy scores are actually negatively related to intelligence, albeit weakly. Furthermore, it was reported in the same meta-analytic work that the various dimensions of psychopathy were differentially related to intelligence. Importantly, virtually all of the research to date has relied on cross-sectional associations. The current study examined whether intelligence scores (verbal comprehension, nonverbal IQ, and a global intelligence composite) at age 8 were associated with psychopathy scores at age 48 in a sample of White, urban male individuals from London (analytical n = 292). Results suggested a significant, but weak, inverse association between intelligence and the affective, lifestyle, and antisocial facets of psychopathy and a nonsignificant association with the interpersonal facet, as assessed by the Psychopathy Checklist: Screening Version. These findings contribute to the growing body of evidence suggesting that psychopathy, as conceptualized in most modern models, is either very weakly inversely related to or simply not a correlate of intelligence.

Examining psychopathic traits at the factor or facet level has revealed that various aspects of psychopathy may be differentially related, even in opposing directions, to important outcomes (e.g., intelligence, emotion regulation). Empirical work on relations between psychopathy and internalizing disorders, such as posttraumatic stress disorder (PTSD) and depression, has provided evidence for a positive association with antisocial traits. However, findings for the affective domain have been more equivocal. The current study (N = 732) sought to replicate past findings of the positive association of antisocial psychopathic traits with higher levels of PTSD and depressive symptoms, and to further explore associations between affective traits of psychopathy and these disorders using two measures of psychopathy. Results confirmed prior findings of a positive correlation between antisocial features and self-reported PTSD/Depression symptom severity, but they did not provide evidence for any association with affective traits. Future research using longitudinal designs is needed to begin establishing temporal ordering of the psychopathy-internalizing relationship.

Increasing evidence indicates that the interaction between testosterone and cortisol is associated with variation in aggressive behavior. However, results are mixed. The current study further explored the association between testosterone, cortisol, and both reactive and proactive aggression in a large sample of university students. Models considered direct and interactive effects between baseline measures of testosterone and cortisol as well as change in hormones in response to a social stressor. In women, baseline cortisol had a negative direct association with reactive aggression and was further associated with reactive aggression in interaction with baseline testosterone (positive interaction). Hormones were unrelated to reactive aggression in men. Baseline cortisol had a negative direct association with proactive aggression in women. In contrast, the association between change in cortisol and proactive aggression was positive. Cortisol was not associated with proactive aggression in men. In addition, testosterone was not related to proactive aggression either directly or in interaction with cortisol in either men or women. Collectively, these results show that the association between hormones and aggression varies across aggressive behavior type and across sex.

Incarceration rates in the U.S. rank among the highest in the developed world. Large representative studies have revealed that approximately one third of individuals report having been arrested, or in some other way contacted by the justice system, at some point in their life. A natural outgrowth of this is the need to consider strategies aimed at preventing further CJ contact. Complicating the situation further is that incarcerated populations also report disproportionately high levels of both psychiatric disturbances in general, and ADHD symptomology in particular. Thus, much debate remains around the topic of preventing recidivism. We discuss the possibility of incorporating pharmacological interventions as adjuvant therapies directed toward preventing re-offending. In particular, we explore whether stimulant medications might provide additional return on investment on top of therapies already known to be effective. Given the virtual absence of evidence on this topic, we also endeavor to provide specific recommendations for designing studies that could yield convincing evidence either for, or against, the inclusion of stimulant medications in the recidivism prevention toolkit.

The current study investigated the internal structure and validity of a self-rating form for the Comprehensive Assessment of Psychopathic Personality (CAPP) model in a large sample consisting of American (n = 463) and Australian (n = 94) undergraduates along with a U.S. community sample (n = 182). More specifically, we explored the factor structure of the CAPP Lexical Rating Scale and examined its associations with measures of psychopathy, antisocial behavior, and broad pathological personality traits. Neither exploratory factor analysis nor bass-ackward analyses supported the six proposed domains. Exploratory factor analysis supported a three-factor structure, generally representing the behavioral, interpersonal, and affective domains of psychopathy. Correlations with conceptually relevant external criteria demonstrated the identified three-factor structure was not superior to the six proposed rational domains with respect to construct validity. Symptom-level analyses supported the use of CAPP symptom as measures of individual symptoms with good convergent validity. Overall, the current study supports the construct validity of the CAPP model, and the Lexical Rating Scale in particular, but more research is needed to further explore the optimal structure of the model.

Objectives: First, we test for differences in various cognitive abilities across trajectories of body mass index (BMI) over the later life course. Second, we examine whether genetic risk factors for unhealthy BMIs-assessed via polygenic risk scores (PRS)-predict cognitive abilities in late-life. Methods: The study used a longitudinal sample of Vietnam veteran males to explore the associations between BMI trajectories, measured across four time points, and later cognitive abilities. The sample of 977 individuals was drawn from the Vietnam Era Twin Study of Aging. Cognitive abilities evaluated included executive function, abstract reasoning, episodic memory, processing speed, verbal fluency, and visual spatial ability. Multilevel linear regression models were used to estimate the associations between BMI trajectories and cognitive abilities. Then, BMI PRS was added to the models to evaluate polygenic associations with cognitive abilities. Results: There were no significant differences in cognitive ability between any of the BMI trajectory groups. There was a significant inverse relationship between BMI-PRS and several cognitive ability measures. Discussion: While no associations emerged for BMI trajectories and cognitive abilities at the phenotypic levels, BMI PRS measures did correlate with key cognitive domains. Our results suggest possible polygenic linkages cutting across key components of the central and peripheral nervous system.
RESUMEN
Despite the prior linkages of low resting heart rate to antisocial behavior broadly defined, less work has been done examining possible associations between heart rate to psychopathic traits. The small body of research on the topic that has been conducted so far seems to suggest an inverse relationship between the two constructs. A smaller number of studies has found the opposite result, however, and some of the previous studies have been limited by small sample sizes and unrepresentative samples. The current study attempts to help clarify the relationship between resting heart rate and psychopathic traits in a large, nationally representative sample (analytical N ranged from 14,173-14,220) using an alternative measure of psychopathic traits that is less focused on antisocial processes, and rooted in personality traits. No significant relationship between heart rate and psychopathic traits, or heart rate and a measure of cold-heartedness, was found. It is possible that previous findings of a link between heart rate and psychopathy have been driven by the inclusion of overt antisocial behavior in many traditional psychopathy measures. Further work is needed to confirm the associations (or lack thereof) between heart rate and the behavioral, affective, and personality trait aspects of psychopathy.

The current study tested the association between physiology and aggressive behavior type in a large sample of University students (N = 509). Measures of aggression were gathered with the Reactive and Proactive Aggression Questionnaire. Analyses used raw aggressive behavior type scores and residualized measures of aggressive behavior type, which account for the overlap between reactive and proactive aggression. Measures of physiology included skin conductance and heart rate, both at rest and in response to a minor social stressor. Analyses assessed the association between aggressive behavior type and measures of physiology in the full sample and in sex specific sub-samples. Results indicated that resting skin conductance was positively associated with proactive aggression in the full sample and among females. Skin conductance in response to stress had a positive association with reactive aggression both in the full sample and among males. Skin conductance responsivity was negatively associated with proactive aggression among males. Findings further strengthen previous work suggesting that the etiologies of reactive and proactive aggression are distinct and may vary across sex.
