The Interplay between Fear Reactivity and Callous-Unemotional Traits Predicting Reactive and Proactive Aggression.

Research has indicated that youths with CU traits are fearless, and this fearlessness plays a bidirectional role in both the development of CU traits and engagement in aggressive behavior. However, research specifically testing the role of fear in the association between CU traits and aggression is scarce. The goal of the current study was to test if fear reactivity, both conscious (self-report) and automatic (skin conductance reactivity; SCR), moderated the association between CU traits and aggression subtypes (reactive and proactive aggression). Participants included 161 adolescents (Mage = 15 years) diagnosed with conduct disorder. CU traits were assessed using the self-report Inventory of Callous-Unemotional Traits. Conscious and automatic fear reactivity were measured during a virtual reality rollercoaster using the Self-Assessment Manikin and skin conductance reactivity (SCR), respectively. Hierarchical regressions found that high fear reactivity on SCR moderated the link between CU traits and reactive aggression, while feeling more excited during fear induction moderated the link between CU traits and proactive aggression. Overall, a possible explanation of our divergent findings between conscious and automatic fear may be the difference between the instinctual biological response to threat versus the cognitive and emotional appraisal and experience of threat. Implications for intervention strategies targeting emotional recognition and regulation in reducing aggression in CD populations are discussed.

Exploring changes in violence across two waves of the COVID-19 pandemic in Richmond, VA.

The first wave of the COVID-19 pandemic carried with it an increase in violence in the United States and abroad. The proportion of violence cases involving firearms also increased during this time, yet little research has examined these effects using data from the second wave of COVID infections. Explanations for these documented increases in gun violence put forward by scholars include increased firearm purchases, alcohol consumption, unemployment, and organized crime activity. The current work examined these trends in Richmond, VA. We collected data on patients (N = 1744) presenting with violent injuries from 2018 to 2022 from the emergency department of a Level-1 Trauma Center in Richmond, VA. Data were coded on the basis of whether they presented before the pandemic, during the first wave, or during the second wave. Logistic binomial regressions revealed that the risk of gunshot wounds increased by 32% during the first wave and 44% during the second wave, relative to the pre-COVID period, but that the increase between the first and second wave was not significant. These findings held after controlling for victim age, race, sex, and injury severity. Further analyses revealed that these effects were specific to violent injury, as we found no increase in firearm use among self-injury cases. The heightened violence reported during the COVID-19 pandemic was also observed in Richmond, VA. Gun violence in particular increased over time as other forms of violence (i.e., assaults, stabbings, and self-harm) decreased.

Identifying distinct profiles of impulsivity for the four facets of psychopathy.

Psychopathy comprises antagonistic personality traits and antisocial behaviors that are associated with critical outcomes for the individual and society (e.g., violent behavior). Since its inception, impulsivity has been theorized as a core feature of psychopathy. Research supports this assertion, yet psychopathy and impulsivity are both multifaceted constructs. As such, the associations commonly observed between psychopathy and impulsivity may obscure more nuanced profiles of impulsivity that are only observable at the facet-level. To address this gap in the literature, we collected data from a community sample using a clinical psychopathy interview along with dispositional and neurobehavioral measures of impulsivity. We regressed each of the four facets of psychopathy onto eight impulsivity variables. We followed these analyses with bootstrapped dominance analyses in order to determine which of the impulsivity variables shared the most variance with each psychopathy facet. Our analyses revealed that positive urgency was the most important aspect of impulsivity to all four facets of psychopathy. We further identified distinct profiles of impulsivity linked to each psychopathy facet-the interpersonal facet was typified by sensation seeking and temporal impulsivity. The affective and lifestyle facets were both typified by general trait impulsivity and affective impulsivity. The antisocial facet was typified by affective impulsivity and sensation seeking. Such distinct profiles of impulsivity suggest that specific behaviors linked with each facet (e.g., manipulativeness and the interpersonal facet) may be explained in part by the distinct forms of impulsivity aligned with them.

Psychopathy and substance use predict recidivism in women: A 7-year prospective study.

Recidivism places a significant burden on society and efforts aimed at reducing cyclical criminal justice involvement are needed. This prospective study tested the utility of psychopathic traits in predicting general, felony, and substance-related rearrest in women following release from a correctional facility. The extent to which psychopathic traits offered incremental utility in predicting outcomes, above and beyond other established risk factors, including substance use disorder, was examined. Participants included 327 incarcerated adult women who completed comprehensive clinical and psychiatric assessments prior to release from correctional facilities. Psychopathic traits and lifetime substance use disorder were measured using the Hare Psychopathy Checklist-Revised (PCL-R) and Structured Clinical Interview for DSM-IV-TR Axis I Disorders, respectively. Results showed that general, felony, and substance-related rearrest following institutional release were associated with higher PCL-R Factor 2 scores, assessing lifestyle/behavioral and antisocial/developmental psychopathic traits. Additionally, when controlling for other risk factors associated with recidivism, including age at release, number of prior adult prison terms, and substance use disorder, higher PCL-R Factor 2 scores remained significantly associated with rearrest outcomes in women. Findings inform risk prediction and treatment efforts aimed at reducing recidivism in justice-involved women. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Comparing psychopathy across measurement modalities.

Psychopathy is a collection of personality traits and behaviors that are associated with costly personal, interpersonal, and societal outcomes. The nature of this construct has been widely debated across decades of literature, and such debates have produced a multitude of instruments for the measurement of psychopathy. These measures include self-reports and clinical interviews, yet little work has examined the degree to which measurements of psychopathy may differ across these modalities and whether such potential differences may impact the associations commonly found with psychopathy (e.g., impulsivity). To this end, we applied psychometric network and item response theory analyses to data obtained from the interview-based Psychopathy Checklist: Screening Version and the Levenson Self-Report of Psychopathy in the same sample. Our results revealed similarities and differences across measurement modalities. Regarding the Psychopathy Checklist: Screening Version, Factor 2 items were more important to the psychopathy construct (i.e., the most central and contributed more information than Factor 1 items), whereas Factor 1 items were more important to the Levenson Self-Report of Psychopathy. Factor 1 items were positively linked with Positive Urgency and were either negatively associated or not associated with Negative Urgency. In contrast, Factor 2 items were positively linked with Negative Urgency in both networks. Our analyses also revealed that dishonesty and irresponsibility served as the primary bridges connecting the factors of psychopathy in both networks. We make suggestions for improving the assessment of psychopathy by implementing self-report and interview measures that allow scores to be compared directly.

Comparing forms of neighborhood instability as predictors of violence in Richmond, VA.

Violence events tend to cluster together geospatially. Various features of communities and their residents have been highlighted as explanations for such clustering in the literature. One reliable correlate of violence is neighborhood instability. Research on neighborhood instability indicates that such instability can be measured as property tax delinquency, yet no known work has contrasted external and internal sources of instability in predicting neighborhood violence. To this end we collected data on violence events, company and personal property tax delinquency, population density, race, income, food stamps, and alcohol outlets for each of Richmond, Virginia's 148 neighborhoods. We constructed and compared ordinary least-squares (OLS) to geographically weighted regression (GWR) models before constructing a final algorithm-selected GWR model. Our results indicated that the tax delinquency of company-owned properties (e.g., rental homes, apartments) was the only variable in our model (R2 = 0.62) that was associated with violence in all but four Richmond neighborhoods. We replicated this analysis using violence data from a later point in time which yielded largely identical results. These findings indicate that external sources of neighborhood instability may be more important to predicting violence than internal sources. Our results further provide support for social disorganization theory and point to opportunities to expand this framework.

Gun Violence and Psychopathy Among Female Offenders.

Research exploring risk factors of gun violence is limited, especially research involving women as perpetrators of violence. Yet, women account for 18-21% of convicted violent crime. The present study aimed to test if psychopathy, a notable risk factor for violence, was related to past convictions of gun violence, general forms of violence, and non-violent crime. In a sample of 206 female offenders, multinomial logistic regressions assessed how interpersonal, affective, and behavioral psychopathic traits increased the likelihood of women belonging to the gun violence group, a violent crime group, and a non-violent crime group. Results showed the interpersonal and affective facets increased the likelihood of women belonging to the gun violence group compared to both the violent and non-violent crime groups. The behavioral facet increased the likelihood of women belonging to the violent crime group when compared to the gun violence and non-violent crime groups. These results suggest that gun violence has different risk factors than violent and non-violent crime. This line of inquiry indicates that existing violence prevention strategies may need to be modified to address gun violence.

Skin Conductance Responses to a Discrete Threat in Virtual Reality: Associations with Psychopathy and Anxiety.

People with high levels of psychopathic traits are often described as fearless and lacking in emotional depth, particularly when evaluating threats in their environments. Skin conductance responsivity (SCR) to negative emotional stimuli represents a robust autonomic correlate of conduct problem behavior in children (Fanti et al., in Neuroscience and Biobehavioral Reviews, 100, 98-107, 2019). However, studies that have examined threat-related processing in youth with conduct problems have tended to use a variety of negative stimuli that might induce various and unspecific negative emotions. Few studies have taken in to account the moderating effects of anxiety on the relationship of distinct psychopathic traits (e.g., narcissism, callousness, impulsivity) with SCR to a fear inducing stimulus. In this study, we examined SCR to a virtual reality rollercoaster drop - that is, a discrete fear inducing event - in a sample of 75 youths (61 males; M = 14 years, SD = 1.4) enrolled in a non-mainstream school. The rollercoaster drop was used to more clearly examine an event-related response to a discrete threat, rather than examining SCR throughout the rollercoaster ride. We used the teacher-reported Antisocial Process Screening Device (Frick & Hare, in Antisocial process screening device: APSD. Toronto: Multi-Health Systems, 2001) to examine the relations of distinct psychopathic traits with SCR and self-reported anxiety. Lower anxiety was associated with higher callousness, but only in youths with low SCR to discrete threat. These findings suggest that fear and anxiety show complex and interactive relations with distinct psychopathic traits.

Fluid Intelligence Moderates the Link Between Psychopathy and Aggression Differently for Men and Women.

Research on sex differences in the association of psychopathy with fluid intelligence is limited, and it remains unknown if fluid intelligence plays a meaningful role in explaining the psychopathy-aggression link for men and women. The present study aimed to test for sex differences in the relation between the four-facet model of psychopathy and intelligence, and to assess whether fluid intelligence moderates the link between psychopathy and aggression. In a community sample of men (n = 356) and women (n = 196), we assessed psychopathy using the Psychopathy Checklist: Screening Version (PCL:SV), fluid intelligence using the Raven's Progressive Matrices, and types of aggression using the Aggression Questionnaire (AQ). Hierarchical regressions showed that the psychopathy lifestyle facet was negatively associated with intelligence and there were no sex differences. Our analyses for types of aggression revealed sex differences and similarities. For both men and women, total AQ scores were predicted by higher antisocial facet scores. Lower intelligence moderated the link between higher antisocial facet scores and aggression in men, but not for women. Physical aggression in women was associated with higher interpersonal, affective, and antisocial facet scores, whereas for men, it was only associated with higher antisocial facet scores. Verbal and indirect aggression were associated with higher intelligence in both men and women. For men only, higher antisocial facet scores were associated with verbal and indirect aggression. Higher intelligence moderated the link between the lifestyle facet and indirect aggression for women, whereas for men, it moderated the link between the affective facet and indirect aggression. This study further highlights sex differences in mechanisms of psychopathy-related aggression, which need to be considered in the development of violence interventions and risk assessment.

Interpersonal Trauma Among Women and Men Receiving Buprenorphine in Outpatient Treatment for Opioid Use Disorder.

People with opioid use disorder (OUD) are vulnerable to negative health outcomes related to substance use and psychosocial issues, such as interpersonal trauma (IPT). Participants receiving buprenorphine completed a cross-sectional survey (July-September 2019). OUD outcomes were prospectively abstracted over a 28-week timeframe. More than a third reported recent IPT (40% women, 36% men). Sexual violence was more common among women than men (p = .02). For women only, IPT was associated with substance use during follow-up (ß = 20.72, 95% CI: 4.24, 37.21). It is important for public health strategies in the opioid crisis to address IPT using sex- and gender-informed approaches.

Reflexive Gaze Shifts and Fear Recognition Deficits in Children with Callous-Unemotional Traits and Impulsivity/Conduct Problems.

The ability to efficiently recognize the emotions on others' faces is something that most of us take for granted. Children with callous-unemotional (CU) traits and impulsivity/conduct problems (ICP), such as attention-deficit hyperactivity disorder, have been previously described as being "fear blind". This is also associated with looking less at the eye regions of fearful faces, which are highly diagnostic. Previous attempts to intervene into emotion recognition strategies have not had lasting effects on participants' fear recognition abilities. Here we present both (a) additional evidence that there is a two-part causal chain, from personality traits to face recognition strategies using the eyes, then from strategies to rates of recognizing fear in others; and (b) a pilot intervention that had persistent effects for weeks after the end of instruction. Further, the intervention led to more change in those with the highest CU traits. This both clarifies the specific mechanisms linking personality to emotion recognition and shows that the process is fundamentally malleable. It is possible that such training could promote empathy and reduce the rates of antisocial behavior in specific populations in the future.

Psychophysiological underpinnings of proactive and reactive aggression in young men and women.

Reactive aggression is posited to occur as a result of hypersensitivity to threat, whereas fearlessness may drive proactive aggression. This study aimed to test if physiological fear reactivity differentially relates to self-report reactive and proactive aggression using immersive virtual reality fear (VR) induction. We collected subjective fear ratings and sympathetic (SNS; skin conductance) and parasympathetic (PNS; respiratory sinus arrhythmia) nervous system reactivity during an interactive VR horror video. Results showed that for men and women, reactive aggression was related to heightened SNS fear reactivity. For men, proactive aggression was related to hypoarousal of the PNS and SNS (coinhibition) during fear induction, whereas augmented PNS was related to proactive aggression in women. These results support the fearlessness hypothesis for proactive aggression in men, but this does not replicate in women. By contrast, hypersensitivity to fear is related to reactive aggression for both men and women.

Effects of Psychopathy on Neurocognitive Domains of Impulsivity in Abstinent Opiate and Stimulant Users.

Background: Psychopathy and substance use disorders (SUDs) are both characterized by neurocognitive impairments reflecting higher levels of impulsivity such as reward-driven decision-making and deficient inhibitory control. Previous studies suggest that psychopathy may exacerbate decision-making deficits, but it may be unrelated to other neurocognitive impairments among substance dependent individuals (SDIs). The aim of the present study was to examine the role of psychopathy and its interpersonal-affective and impulsive-antisocial dimensions in moderating the relationships between dependence on different classes of drugs and neurocognitive domains of impulsivity. Method: We tested 693 participants (112 heroin mono-dependent individuals, 71 heroin polysubstance dependent individuals, 115 amphetamine mono-dependent individuals, 76 amphetamine polysubstance dependent individuals, and 319 non-substance dependent control individuals). Participants were administered the Psychopathy Checklist: Screening Version (PCL:SV) and seven neurocognitive tasks measuring impulsive choice/decision-making (Iowa Gambling Task; Cambridge Gambling Task; Kirby Delay Discounting Task; Balloon Analog Risk Task), and impulsive action/response inhibition (Go/No-Go Task, Immediate Memory Task, and Stop Signal Task). Results: A series of hierarchical multiple regressions revealed that the interpersonal-affective dimension of psychopathy moderated the association between decision-making, response inhibition and both amphetamine and heroin dependence, albeit differently. For amphetamine users, low levels of interpersonal-affective traits predicted poor decision-making on the Iowa Gambling Task and better response inhibition on the Stop Signal task. In contrast, in heroin users high interpersonal-affective psychopathy traits predicted lower risk taking on the Cambridge Gambling Task and better response inhibition on the Go/No-Go task. The impulsive-antisocial dimension of psychopathy predicted poor response inhibition in both amphetamine and heroin users. Conclusions: Our findings reveal that psychopathy and its dimensions had both common and unique effects on neurocognitive function in heroin and amphetamine dependent individuals. Our results suggest that the specific interactions between psychopathy dimensions and dependence on different classes of drugs may lead to either deficient or superior decision-making and response inhibition performance in SDIs, suggesting that psychopathy may paradoxically play a protective role for some neurocognitive functions in specific subtypes of substance users.

Anxiety Mediates the Link Between Psychopathy and Aggression in NGRI Acquittees.

Psychopathy has been long associated with anxiety, and anxiety has been argued to play an important role in psychopathy-related behaviors, such as aggression. However, these associations have not yet been explored in Not Guilty by Reason of Insanity (NGRI) Acquittees. The goals of the present study were to test the correlations between the 4-facet psychopathy construct and anxiety, and to assess whether anxiety mediates the association between psychopathy and aggression. In a sample of 81 NGRI acquittees, anxiety was positively related to the lifestyle facet. When testing the mediating role of anxiety on the psychopathy-aggression link, the results showed that low anxiety mediated the link between the interpersonal facet and aggression. By contrast, high anxiety mediated the link between the lifestyle facet and aggression. These results highlight the disparate associations between specific psychopathy features and anxiety in predicting aggressive behavior. The present findings demonstrate that violence reduction strategies may need to become more tailored to individual needs when it comes to reducing risk among people with varying levels of psychopathic traits and serious mental illness.

Physical Abuse Explains Sex Differences in the Link Between Psychopathy and Aggression.

Psychopathy has long been associated with aggression. However, few studies have looked at differences between men and women. Studies that do exist demonstrate that psychopathy differentially relates to aggression in men and women and indicate that environmental factors may play a significant role in influencing these associations. A key environmental factor is a history of lifetime physical abuse (LPA), which has been linked to aggressive behavior in both men and women. The aim of the present study was to test if psychopathy differentially predicted physical, verbal, and indirect aggression in men and women, and if these associations were moderated by LPA. In a large community sample of men (n = 369) and women (n = 204), we assessed the 4-facet model of psychopathy (Interpersonal, Affective, Lifestyle, Antisocial) with the Psychopathy Checklist: Screening Version, LPA with the Addiction Severity Index, and self-report aggression with the Aggression Questionnaire. Results revealed sex differences and similarities. Physical aggression was associated with the affective facet of psychopathy in both men and women, though in different directions based on the moderating effects of LPA. Verbal aggression was associated with higher antisocial facet scores and LPA for men and not women. Finally, indirect aggression was associated with the antisocial facet of psychopathy for men, and the interpersonal facet for women, and these associations were not moderated by LPA. In women, low antisocial facet scores and no LPA were found to be protective for indirect aggression. These results show that LPA and psychopathy generally increase the risk of aggression, but the interaction between LPA and psychopathy differentiates the risk of aggression forms for men and women. These sex differences highlight the need for female-responsive interventions to target sex-specific risk factors for aggressive behavior.

The Impact of Parental Incarceration on Psychopathy, Crime, and Prison Violence in Women.

There is a growing interest in understanding the consequences of parental incarceration. Unfortunately, research exploring the long-term criminological and personality effects in female offspring is limited, particularly among second-generation female offenders. In a sample of 170 female offenders, we first assessed the correlations between psychopathy facets, prison violence, and types of crime. Next, we tested the association between childhood exposure to paternal and/or maternal incarceration on adulthood psychopathic traits, criminal offending, and prospective prison violence over 12 months. Correlations showed the interpersonal facet was positively correlated with fraud-related crime and prison violence. The affective facet was positively correlated with violent crime and prison violence. The behavioral facet was associated with prison violence and drug-related crime. Multinomial logistic regressions showed higher interpersonal facet scores were associated with an increased likelihood of having experienced paternal incarceration. Higher affective facet scores, violent crime, and prison violence were associated with an increased likelihood of having experienced maternal incarceration, regardless of if the father had been incarcerated or not. It is evident that having any parent incarcerated during childhood can be harmful to daughters; however, our findings dovetail with prior research showing that maternal incarceration leads to more detrimental outcomes for women.

Callous-unemotional traits and fearlessness: A cardiovascular psychophysiological perspective in two adolescent samples using virtual reality.

There has been a longstanding debate about the link between callous-unemotional traits and fearlessness. However, biological evidence for a relationship in adolescents is lacking. Using two adolescent samples, we measured emotional reactivity and cardiac measures of sympathetic (pre-ejection period) and parasympathetic (respiratory sinus arrhythmia) reactivity during 3D TV and virtual reality fear induction. Study 1 included 62 community adolescents from a stratified sample. Study 2 included 60 adolescents from Emotional and Behavioral Difficulties schools. Results were consistent across both studies. Adolescents with high callous-unemotional traits showed coactivation of the sympathetic and parasympathetic nervous system. Consistent with these results, youths with callous-unemotional traits self-reported that they felt more in control after the fear induction. Thus, in both samples, youth with callous-unemotional traits displayed a physiological and emotional profile suggesting they maintained control during fear induction. Therefore, it is proposed here that a shift in thinking of youth with callous-unemotional traits as fearless to youth with callous-unemotional traits are better able to manage fearful situations, may be more appropriate.

An Exploratory Study of Female Psychopathy and Drug-Related Violent Crime.

There is a clear link between drugs and violence, and the extensive burden drug-related violence inflicts on society. However, drug-related violence is largely understudied, especially in female populations. The aim of the present study was to explore whether women convicted of drug-related violent crime differed on individual-level risk factors from women convicted of a nondrug-related violent crime and women convicted of nonviolent crimes. One hundred and twenty-five female inmates were classified using official criminal records. Multinomial logistic regression indicated inmates higher in antisocial psychopathic traits and low level of educational attainment were more likely to be in the drug-related violent crime group. In comparison, inmates higher in callous psychopathic traits were more likely to be in the nondrug-related violent crime group. Using official records of prison misconduct, a secondary aim tested whether prison violence increased the likelihood of being in either of the violent crime groups. Results show inmates who had committed violent misconducts over a 6-month period were more likely to be the nondrug-related violent crime group. Prison violence did not differentiate inmates in the nonviolent crime group from the drug-related violent crime group. These findings are the first to explore the relation between psychopathy and drug-related violent crime, and drug-related violent crime predicting future violent behavior in female criminals. This study demonstrates the heterogeneity in female violent behavior. Furthermore, psychopathy is not only shown to be an important risk factor for violence in women but also highlights that the dimensional construct is essential for understanding context-dependent violence.

Critical call for hospital-based domestic violence intervention: The Davis Challenge.

BACKGROUND: Fifty percent of women killed in intimate partner violence (IPV) were seen by a health care provider within a year of their death. As guest speaker to Virginia Commonwealth University Trauma Center (VCU-TC), Dr. James Davis (Western Trauma Association past president) challenged VCU-TC to develop a hospital-based IPV program. This research examines the development and impact of an integrated hospital/VCU-TC-based IPV program. METHODS: The IPV survey was carried out to determine need for training and screening. Hospital forensic nurse examiners case logs were evaluated to determine IPV prevalence. An integrated IPV program-Project Empower was developed, consisting of staff education, patient screening, victim crisis fund, and interdisciplinary sexual assault/domestic violence intervention team. Between 2014 and 2018, patients admitted with an IPV consult to Project Empower were entered into a secure database capturing demographics, mechanisms, income data, and social determinants of risk. Program feasibility was evaluated on patient engagement via screening and case management. Program impact was evaluated on crisis intervention, safety planning, and community referral. RESULTS: Forensic nurse examiner data and IPV survey evaluation noted 20% IPV prevalence and lack of IPV screening and training. The IPV patients (N = 799) were women (90%), unmarried (79%) and African-American (60%). Primary mechanisms were firearm (44%) or stabbing (34%). Survivors were perpetrated by a cohabiting (42%) or dating partner (18%). Monthly income averaged US $622. Forty percent had no health insurance. Advocates provided 62% case management. Survivors received victim crisis funds (16%), safety planning (68%), crisis intervention (78%), sexual and domestic violence education (83%), and community referral (83%). Within 5 years, 35 (4%) were reinjured and seen in the emergency department. Thirty-one (4%) were readmitted for IPV-related injuries. Two deaths were attributed to IPV. CONCLUSION: Critical call for hospital-based IPV intervention programs as a priority for trauma centers to adopt cannot be underestimated but can be answered in a comprehensive integrated model. LEVEL OF EVIDENCE: Therapeutic, level I.

Which features of psychopathy and impulsivity matter most for prison violence? New evidence among female prisoners.

Prison violence is a complex and multifaceted phenomenon. While a great deal of research has been conducted in male samples, very few studies are dedicated to understanding violence committed by female offenders. Two constructs that have emerged as important predictors of violence are psychopathy and impulsivity. These constructs may be an important line of inquiry due to the close association between psychopathy, impulsivity, and violence. In a sample of 166 female offenders, we used the 3-facet model of psychopathy and 3-factor model of trait impulsivity with the goal to statistically explain two types of prison violence: official reports of violent misconducts over a 12-month period, and self-report of deliberately instigating a violent altercation. We conducted three separate regression models to test the independent contribution of psychopathy and impulsivity, as well as accounting for the overlap between psychopathy and impulsivity. When impulsivity and psychopathy were not competing within the same model, affective and behavioral psychopathic traits, and nonplanning impulsiveness predicted violent misconducts. However, when accounting for impulsivity and psychopathy within the same model, only affective psychopathic traits remained significant. When predicting if an offender deliberately started a violent altercation, separate statistical models showed affective and interpersonal psychopathic traits, and nonplanning impulsiveness were significant. When competing for variance within the same statistical model, only affective and interpersonal psychopathic traits remained as significant predictors. This suggests an overlap between psychopathic traits and nonplanning impulsivity when understanding violent misconducts in female offenders, while affective psychopathic explains female prison violence, regardless of impulsivity.
