Development and Preliminary Validation of a Self-Report Measure of Psychopathic Personality Traits in Noncriminal Population

Research on psychopathy has been hindered by persisting difficulties and controversies regarding its assessment. The primary goals of this set of studies were to (a) develop, and initiate the construct validation of, a self-report measure that assesses the major personality traits of psychopathy in noncriminal populations and (b) clarify the nature of these traits via an exploratory approach to test construction. This measure, the Psychopathic Personality inventory (PPI), was developed by writing items to assess a large number of personality domains relevant to psychopathy and performing successive item-level factor analyses and revisions on three undergraduate samples. The PPI total score and its eight subscales were found to possess satisfactory internal consistency and test-retest reliability. In four studies with undergraduates, the PPI and its subscales exhibited a promising pattern of convergent and discriminant validity with self-report, psychiatric interview, observer rating, and family history data. In addition, the PPI total score demonstrated incremental validity relative to several commonly used self-report psychopathy-related measures. Future construct validational studies, unresolved conceptual issues regarding the assessment of psychopathy, and potential research uses of the PPI are outlined.     

Exploring Associations Between Psychopathic Personality and Components of Disinhibition vs. Constraint

Recent models of psychopathy implicate Disinhibition vs. Constraint (DvC) as one of the primary underpinnings of psychopathic traits, although little research has examined associations between specific DvC components and psychopathy facets. The present study aimed to fill this gap by examining associations between psychopathy facets, as operationalized by two widely used self-report psychopathy instruments, and lower-order components of DvC within a racially diverse sample of 1,160 undergraduates. Path analyses confirmed the broad dimension of DvC as representing a general diathesis to psychopathy, with second-order components conferring more specific risks for particular psychopathy traits regardless of the model of psychopathy employed. Further, findings suggest that associations do not vary by race. Results suggest both generality and specificity of DvC dimensions as they relate to psychopathic traits, as well as potential avenues for further investigation of the associations between psychopathy and DvC.     

Socioeconomic Status and Psychopathic Traits in a Community Sample of Youth

The current study aims to address socioeconomic status (SES) as a moderating variable between psychopathic traits and conduct problems in a sample of 2432 Dutch adolescents (M_age?=?14.50 years, SD?=?1.67, 56% male). Both family and neighborhood SES were measured, with income as a proxy for the level of SES. There were small but significant positive correlations between the behavioral and interpersonal dimensions of psychopathy and family SES, a small but significant negative correlation between the affective dimension and neighborhood SES, and a small and significant positive correlation between neighborhood SES and the behavioral dimension of psychopathy. Results further showed that the relations between youth psychopathic traits were moderated by neither family SES nor neighborhood SES. The results suggest that the relations between psychopathic traits and conduct problems are equally strong for lower and higher SES youth. Taken together, these findings warrant the conclusions that SES does not play a role as a moderator in the relation between psychopathy and conduct problems.     

Interaction between Prenatal Maternal Stress and Autonomic Arousal in Predicting Conduct Problems and Psychopathic Traits in Children

Evidence has suggested that neurobiological deficits combine with psychosocial risk factors to impact on the development of antisocial behavior. The current study concentrated on the interplay of prenatal maternal stress and autonomic arousal in predicting antisocial behavior and psychopathic traits. Prenatal maternal stress was assessed by caregiver’s retrospective report, and resting heart rate and respiratory sinus arrhythmia (RSA) were measured in 295 8- to 10-year-old children. Child and caregiver also reported on child’s antisocial behavior and psychopathic traits. Higher prenatal maternal stress was associated with higher caregiver-reported antisocial and psychopathy scores, even after the concurrent measure of social adversity was controlled for. As expected, low heart rate and high RSA were associated with high antisocial and psychopathic traits. More importantly, significant interaction effects were found; prenatal stress was positively associated with multiple dimensions of psychopathic traits only on the conditions of low arousal (e.g., low heart rate or high RSA). Findings provide further support for a biosocial perspective of antisocial and psychopathic traits, and illustrate the importance of integrating biological with psychosocial measures to fully understand the etiology of behavioral problems.     

Associations Between Symptoms of Borderline Personality Disorder,Externalizing Disorders,and Suicide-Related Behaviors

Borderline personality disorder and externalizing disorders are associated with suicide-related behaviors. The present study examined whether symptoms of borderline personality disorder mediate the relationship between externalizing disorders and suicide-related behaviors. Diagnostic interviews were administered to 344 participants (n = 233 women). Results indicated that symptoms of antisocial personality disorder, alcohol use disorders, and drug use disorders each were significantly associated with suicide threats and self-injurious behavior in women and symptoms of antisocial personality disorder were associated with suicide attempts in women. With the exception of the association between symptoms of alcohol dependence and self-injurious behaviors, borderline personality disorder symptoms mediated or partially mediated all associations between externalizing disorders and suicide-related behaviors in women. These results highlight the importance of assessment and treatment of borderline personality disorder symptoms in individuals with externalizing disorders, particularly in the presence of suicide-related behaviors.

Self-Reported Psychopathic Traits in Children: Their Stability and Concurrent and Prospective Association with Conduct Problems and Aggression

The current study investigated the 18-month stability of self-reported psychopathic traits measured through the Youth Psychopathic traits Inventory–Child Version (YPI-CV) and their concurrent and prospective associations with conduct problems and aggression in a sample of 9–12 year olds (n = 159, 52% boys) from the community. Self-reported psychopathy scores were moderately to highly stable and traits were positively related to conduct problems both concurrently and at follow-up, the latter even after controlling for initial levels of conduct problems. Higher self-reported psychopathic traits were also related to higher reactive, but particularly proactive aggression at follow-up. Finally, children with persistently high levels of psychopathic traits exhibited higher levels of conduct problems and proactive aggression at follow-up than those with unstable or stable low psychopathic traits.     

Unique and Interactive Associations of Callous-Unemotional Traits,Impulsivity and Grandiosity with Child and Adolescent Conduct Disorder Symptoms

The construct of psychopathy remains underrepresented in the clinical diagnosis of Conduct Disorder (CD) as the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) only addresses one out of the three dimensions of child psychopathy, Callous Unemotional (CU) traits. This study tests if and to what extent there are unique and interactive associations of CU traits, impulsivity, and grandiosity with child and adolescent CD symptoms. Data were collected from two separate community samples of children (N?=?1599; Mage?=?9.46, SD?=?1.65; 52% female) and adolescents (N?=?2719; Mage?=?16.99, SD?=?0.99; 49% female), who were followed longitudinally after a year. Hierarchical linear regression analyses were conducted, testing cross-sectional and longitudinal associations with CD symptoms, taking into account all three psychopathy dimensions. The cross-sectional findings indicate that only youth presenting a combination of all three psychopathy dimensions scored above the clinical cut-off score for CD. On the other hand, longitudinal findings provided evidence that the combination of high initial levels of CD and CU traits as well as the combination between CD, grandiosity, and impulsivity can lead to clinical levels of future CD symptoms. Findings also indicated that CU traits and impulsivity more strongly predicted adolescent than child CD symptoms, and that CU traits were more strongly associated with boys’ than girls’ CD symptoms. Findings support the inclusion of CU traits as a specifier for the diagnosis of CD, and provide evidence that other psychopathy dimensions can also help clinicians to better understand and treat youth with CD, and should be considered for future revisions of the DSM.     

Psychopathic Traits in Adolescence and the Five Factor Model of Personality

The present study aimed to expand work on psychopathic traits and the Five Factor Model (FFM; Costa and McCrae 1992). The associations between the three factors of psychopathy and personality traits—assessed by means of the Youth Psychopathic Traits Inventory (YPI, Andershed et al. 2002) and the Neuroticism, Extraversion, Openness Personality Inventory-Revised (NEO PI-R; Costa and McCrae 1992)—were explored in a community sample of 152 male adolescents and young adults. The unique relations of each YPI subscale with the NEO domains/facets were examined by computing partial correlations controlling for the scores on the other two YPI psychopathy subscales. The YPI Callous/Unemotional dimension exhibited negative associations with Extraversion, Openness, and Agreeableness. The YPI Impulsive/Irresponsible factor was positively associated with Extraversion and negatively with Conscientiousness. The YPI Grandiose/Manipulative factor displayed positive associations with Openness and Conscientiousness. We discuss the implications of the differential associations of the three psychopathy factors with the Five Factor domains/facets for theories of the etiology of psychopathy.     

Gender Differences in Psychopathic Traits,Types, and Correlates of Aggression Among Adjudicated Youth

The current study investigated gender differences in types and correlates of aggression among 150 adjudicated youth (M age = 15.2, SD = 1.4). In cluster analysis, consistent with past studies, one aggressive group characterized by moderate levels of reactive aggression and one characterized by high levels of proactive and reactive aggression emerged and these patterns were consistent across gender. For both boys and girls, the combined proactive/reactive aggression cluster showed the greatest levels of aggression, impulsivity, and callous-unemotional traits, supporting a severity over a typology model of proactive and reactive aggression. Girls displayed significantly higher rates of physical and relational aggression than boys. Girls were highly aggressive toward both girls and boys, whereas boys were highly aggressive only toward other boys. Girls also showed multiple indications of severity and emotionality, indexed by higher rates of negative affect, anxiety, distress about social provocations, and empathy.     

Associations Between Lower Order Facets of Personality and Dimensions of Mental Disorder

Although there is a plethora of research documenting the relations between broad personality traits and psychopathology, there is decidedly less on the relations between lower order facets and psychopathology. In the current study, we explored the associations between lower order personality traits and dimensions of mental disorder. A combined sample of undergraduates and outpatients completed self-reports of personality and mental disorder. Symptom counts of mental disorders were factor analyzed, and a higher order three-factor solution emerged. One factor was substance use disorder (SUD), and internalizing branched into distress and fear. These dimensions were regressed on facets from the Big Five model of personality. SUD was significantly predicted by high excitement-seeking from the extraversion domain and low self-discipline from conscientiousness. Distress and fear were indistinguishable from one another but showed a different pattern of relations from SUD. High anxiety and depression from neuroticism, low gregariousness from extraversion, high aesthetics and low actions from openness, low trust and high tender-mindedness from agreeableness, and low self-discipline from conscientiousness significantly predicted distress and fear. The findings demonstrate that lower order traits within a single domain have complex relations with psychopathology, which are shrouded when examining broad, higher order traits. Assessment and treatment implications are discussed.     

Disentangling the Associations Between Autistic-Like and Internalizing Traits: A Community Based Twin Study

Internalizing difficulties are prevalent in children with autism spectrum disorders (ASD), yet little is known about the underlying cause of this comorbidity. It is also unclear which types of autistic-like and internalizing difficulties are most strongly associated. The current study investigated the phenotypic and etiological associations between specific autistic-like traits and internalizing traits within a population-based sample. Parent-reported data were analyzed from 7,311 twin pairs at age 7 to 8?years. Structural equation modeling revealed distinguishable patterns of overlap between the three autistic-like traits (social difficulties, communication problems and repetitive/restricted behaviors) and four subtypes of internalizing traits (social anxiety, fears, generalized anxiety, negative affect). Although all phenotypic associations were modest (rph?=?0.00-0.36), autistic-like communication impairments and repetitive/restricted behaviors correlated most strongly with generalized anxiety and negative affect both phenotypically and genetically. Conversely, autistic-like social difficulties showed little overlap with internalizing behaviors. Disentangling these associations and their etiological underpinnings may help contribute to the conceptualization and diagnosis of 'comorbidity' within ASD and internalizing disorders.     

A General Population Twin Study of Conduct Problems and the Auditory P300 Waveform

Reduced amplitude of the P300 event-related potential has been consistently associated with a variety of externalising problems, including conduct disorder. The few available genetically-informative studies of these relationships, however, were conducted among adolescents/adults (i.e., at an age when conduct disorder has typically already become manifest). Among 200 general population twins with a mean age of 9 years (range 6–14 years), we studied the relationship between the P300 waveform elicited by an auditory oddball task and the DSM-oriented conduct problems scale of the Child Behavior Checklist 6–18. Conduct problems scores were negatively and significantly correlated (r?=??0.19, p?=?0.01) with P300 amplitude; correlations between P300 amplitude and the other DSM-oriented Child Behavior Checklist scales were non-significant, except for oppositional defiant problems (p?=?0.01). We found moderate heritability estimates for both P300 amplitude (0.58, CI:0.37;0.73) and conduct problems (0.52, CI:0.25;0.70). Bivariate twin analyses indicated that the covariation between these two phenotypes can be explained by additive genetic factors only, with a genetic correlation of ?0.33. An association between reduced P300 amplitude and conduct problems can be substantiated already in childhood, at an age that precedes the most typical onset of conduct disorder. This relationship appears to be genetic in nature. Reduced P300 amplitude can represent a valuable marker for conduct problems, and can contribute to the early identification of children at high-risk for conduct disorder.     

Untangling Intelligence,Psychopathy, Antisocial Personality Disorder,and Conduct Problems: A Meta‐analytic Review

Substantial research has investigated the association between intelligence and psychopathic traits. The findings to date have been inconsistent and have not always considered the multidimensional nature of psychopathic traits. Moreover, there has been a tendency to confuse psychopathy with other closely related, clinically significant disorders. The current study represents a meta‐analysis conducted to evaluate the direction and magnitude of the association of intelligence with global psychopathy, as well as its factors and facets, and related disorders (i.e. antisocial personality disorder, conduct disorder, and oppositional defiant disorder). Our analyses revealed a small, significant, negative relationship between intelligence and total psychopathy (r = ?.07, p = .001). Analysis of factors and facets found differential associations, including both significant positive (e.g. interpersonal facet) and negative (e.g. affective facet) associations, further affirming that psychopathy is a multidimensional construct. Additionally, intelligence was negatively associated with antisocial personality disorder (r = ?.13, p = .001) and conduct disorder (r = ?.13, p = .001) but positively with oppositional defiant disorder (r = .06, p = .001). There was significant heterogeneity across studies for most effects, but the results of moderator analyses were inconsistent. Finally, bias analyses did not find significant evidence for publication bias or outsized effects of outliers. © 2019 European Association of Personality Psychology     

Looking After Number One: Associations Between Psychopathic Traits and Measures of Social Motivation and Functioning in a Community Sample of Males

Individuals with high levels of psychopathic traits do not typically form enduring bonds with others. However, few studies have documented the associations between psychopathic traits and social functioning. This study systematically explored associations between psychopathic traits and a number of measures characterising social/material goals, social beliefs and the need for belonging, providing a comprehensive assessment of aspects of social functioning associated with psychopathic personality traits. Additionally, a novel experimental vignettes task assessed the extent to which participants identified dominance in themselves and admired this trait in others. Community males with high levels of psychopathic traits appeared not to be motivated by meaningful, long-term relationships. Instead, they seemed to be motivated by goals relating to their own image and financial success. Additionally, these individuals admired dominance in others, but did not clearly identify this trait in themselves. Thus, this study is one of the first to empirically explore multiple areas of social functioning in relation to psychopathic traits, with a view to understanding the social motivations of individuals with high levels of these traits. The findings provide empirical evidence that individuals with high levels of psychopathic traits seem motivated to look after themselves, but not others.     

Integrity Tests and Morality: Associations with Ego Development,Moral Reasoning,and Psychopathic Personality

Although past research has shown links between integrity tests and the Big Five personality traits, little is known about the relationship between integrity and other individual difference constructs used to predict moral behavior. The present study expands this research by examining the relationships between ego development, moral reasoning, psychopathic personality, and three commonly used integrity tests. Both overt and personality‐based integrity tests showed the strongest (negative) correlations with psychopathic personality but only modest correlations with ego development and moral reasoning. On the whole, these findings suggest that integrity tests may be more closely related to overt moral behavior than to moral reasoning.

Psychopathic Personality Traits as Protective Factors against the Development of Post-Traumatic Stress Disorder Symptoms in a Sample of National Guard Combat Veterans

Military personnel often experience post-traumatic stress symptoms following exposure to combat. Personality traits have been identified as possible protective and risk factors in the development of post-traumatic stress disorder (PTSD), and examination of the association between PTSD and personality characteristics provides further insight into this heterogeneous disorder. Psychopathy, frequently conceptualized as collection of pathological personality disturbances relating to deficits in emotionality, empathy, and inhibitory control, includes within its defining features components that may be adaptive in certain situations. In the current study, we sought to expand upon the literature related to personality and PTSD by exploring psychopathic traits as resiliency factors in a military sample. Specifically, facets of psychopathy were analyzed as moderators of the association between combat experience and symptoms of post-traumatic stress disorder within a sample of 292 combat-exposed National Guard and Reserve (NGR) service members. Results indicated that the relationship of combat exposure with PTSD decreased as rates of interpersonal-affective psychopathic traits increased. Impulsive-antisocial traits were also found to moderate the association between combat experience and PTSD, though interestingly there was a similar decrease in magnitude with higher levels of these traits. These findings suggest that particular components of psychopathy may serve as protective factors against the development of PTSD symptomatology within this population.
