Associations Between Conduct Disorder,Neurodevelopmental Problems and Psychopathic Personality Traits in a Swedish Twin Youth Population

Previous research has found a complex relationship between psychopathic traits, neurodevelopmental problems (NDPs), and conduct disorder (CD) in children. This study explores associations between psychopathic traits, assessed with the Child Problematic Traits Inventory—Short Version (CPTI-SV), and CD in children with and without coexisting NDPs (i.e., attention deficit/hyperactivity disorder [ADHD] and autism spectrum disorder [ASD]) in a community-based sample of Swedish twins (n?=?8762). Findings indicate weak to moderately strong correlations between psychopathic traits and CD, ADHD, and ASD, respectively. Furthermore, in univariable analyses, both psychopathic traits and NDPs displayed significant positive associations with being screened positive for CD, though only the grandiose-deceitful dimension of CPTI-SV and the ADHD domain concentration and attention deficits remained significantly associated with CD in a multivariable regression model. The results are relevant to screening and assessment in child and youth psychiatry, as a grandiose and deceitful interpersonal style may also be a valid sign of children at risk of developing CD.     

Common and Distinct Associations Between Aggression and Alcohol Problems with Trait Disinhibition

Disinhibition (vs. Constraint; DvC) represents the tendency to act in an undercontrolled (vs. controlled) manner and has been shown to be strongly linked to externalizing psychopathology. Further, recent research has found lower-order DvC components to have distinct patterns of associations with important externalizing-related outcomes, suggesting that although DvC represents a general diathesis to externalizing behaviors, lower order components likely present more specific risks for particular behaviors. To further characterize the association between components of DvC and externalizing behaviors, the current study aimed to expand upon these recent findings by examining common and distinct associations between components of DvC and aggression and alcohol problems within a large, diverse sample of undergraduates (N?=?933; 36.8 % Black/African-American, 34.3 % White, 14.6 % Asian/Asian-American). Results of structural equation modeling analyses revealed that low Agreeableness and low Self-Control/Premeditation evidenced distinct patterns of associations with externalizing outcomes. Although low Agreeableness and low Self-Control/Premeditation were both associated with all externalizing outcomes, low Agreeableness was most strongly associated with Proactive Aggression whereas low Self-Control/Premeditation was most strongly associated with Reactive Aggression and alcohol problems. These associations did not vary by either race (White vs. African-American) or gender. Further, the three DvC components significantly interacted with one another in explaining these externalizing outcomes. Taken together, these findings suggest both common and distinct associations between DvC and externalizing behaviors that are generalizable to both White and African-American, as well as both male and female, participants. The current study therefore confirms the importance of focusing on lower-order DvC components in future research in service of further explicating differential DvC-related etiological mechanisms associated with various phenotypic expressions of the externalizing spectrum of behavior.     

Associations Between Parental Psychopathic Traits,Parenting, and Adolescent Callous-Unemotional Traits

Research on Child and Adolescent Psychopathology - Callous-unemotional (CU) traits (i.e., callousness, low empathy, shallow affect) have been conceptualized as a downward extension of the...     

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.     

Associations Between Religious Personality Dimensions and Implicit Homosexual Prejudice

Personality correlates of implicit and explicit attitudes toward homosexual and heterosexual individuals were examined within a sample of predominantly Protestant college students in the south-central United States. Implicit attitudes were measured with the Implicit Association Test, a computer program that recorded reaction times as participants categorized symbols (of heterosexual individuals and gay men) and adjectives (good or bad words). Participants also completed self-report measures of religious fundamentalism (RF), Christian orthodoxy (CO), right-wing authoritarianism (RWA), impression management (IM), and attitudes toward heterosexuals, gay men, and lesbians. Participants displayed fairly negative implicit and explicit attitudes toward homosexual relative to heterosexual individuals. Consistent with previous research, RF, CO, RWA, and IM were associated with increases in self-reported homosexual prejudice. Religious fundamentalism was the strongest predictor of a negative implicit attitude toward gay men relative to heterosexuals.     

Child Personality Moderates Associations Between Parenting and Relational and Physical Aggression

Although negative parenting strategies are a risk factor for relational and physical aggression, research has not previously investigated whether child personality traits moderate the association between negative parenting and relational and physical aggression. This was the aim of this study. Participants were mothers of 368 children (172 males, M_age = 11.61, SD = 0.82). Mothers reported on their parenting practices, child personality traits, and child aggression. Results indicated that 2 child personality traits (extraversion and openness) moderated the relationship between inconsistent discipline and relational aggression. Additionally, agreeableness moderated the relationship between poor monitoring and supervision and physical aggression. Specifically, children low on these personality traits showed the highest levels of aggression in the context of negative parenting. These results highlight the importance of examining child personality as a moderator of parental influences on psychopathology development, and emphasize important distinctions between parenting strategies and physical versus relational aggression outcomes.     

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.     

Exploring Associations Between Therapy Factors and Post-therapy Development After Naturalistic Psychotherapies

Earlier research on what contributes to long-term outcome after psychotherapy is scarce and scattered. Responding to this, the current study explores potential associations between therapy factors reported as salient by clients in naturalistic psychotherapy and variation in post-therapy-movement. Material from different codes and categories derived from an earlier content analysis was explored in relation to post-therapy-changes on OQ-45. In the first part of the study, two overarching themes (relational aspects and therapeutic operations) were included in a regression analysis of data from 32 clients. In the second part, more nuanced associations between material from different change- or process categories and post-therapy-movement were explored using data from 20 clients that showed reliable improvement at treatment termination but varied in later development. Reports of material related to relational aspects were recurrently associated with post-therapy improvement. Material suggesting that therapy was experienced as not fully complete (e.g., changes being superficial or wish for more treatment), as well as reports of more positive affect, correlated with later deterioration after improvement at termination. Different processes and changes appreciated by clients during therapy seem to vary as predictors of lasting gains.     

Associations Between the Rotter Incomplete Sentences Blank and Measures of Personality and Psychopathology

The Rotter Incomplete Sentences Blank (RISB; Rotter, Lah, & Rafferty, 1992) is a sentence completion test intended to detect psychological maladjustment. To investigate the construct validity of the measure, we investigated what aspects of personality and psychopathology are correlated with the RISB and also tested the incremental validity of the RISB in a combined sample of clinical (n = 72) and undergraduate participants (n = 69). Interrater reliability of the RISB was good (intraclass correlation > .80). The RISB overall adjustment score discriminated between clinical and undergraduate participants, and high scores on the RISB were associated with higher negative affect, more anxiety and depression, irrational thinking, and interpersonal problems. The incremental validity of the RISB was modest, but it did explain variance in satisfaction with life and personality disorder symptoms above and beyond an extracted measure of general psychological distress. Our findings support the construct validity of the RISB.     

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.     

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.

Investigating the Components of Psychopathic Traits in Youth Offenders

Despite widespread acceptance of the importance of psychopathic traits in youth, the relative importance of different components of psychopathy remains controversial. This study was conducted to examine whether the interpersonal and lifestyle facets of psychopathy as measured with a valid clinical measure of psychopathic traits contribute to predicting relevant external criteria on top of the contributions of the affective facet. To address this issue, we conducted multiple regressions predicting antisocial behavior, exposure to violence, and psychopathology in a sample of 225 incarcerated adolescents. Results indicated that ratings on the affective component of psychopathy were important in helping to explain variance in many of the external criterion variables but that ratings on the interpersonal and lifestyle facets also helped to explain unique variance in a range of criteria including violent and non-violent crime, exposure to violence, impulsivity, and anger expression. These studies suggest that multiple components of psychopathy are likely to be important both in predicting real world outcomes and in understanding mechanisms involved in the development and manifestation of these traits.     

Construct validity of the Psychopathic Personality Inventory in a correctional sample

The relations between the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and 4 theoretically related constructs (empathy, aggression, work ethic, and borderline personality disorder) were examined. Additionally, the relation between the PPI and heroism was explored. One hundred male inmates were administered the PPI, the Questionnaire Measure of Emotional Empathy (Mehrabian & Epstein, 1972), the Aggression Questionnaire (Buss & Perry, 1992), the Protestant Ethic Scale (Mirels & Garrett, 1971), the Self-Report for Borderline Personality Scale (Oldham et al., 1985), and the Activity Frequency Inventory (Lilienfeld, 1998). As predicted, the PPI was significantly negatively correlated with empathy and significantly positively related to aggression and borderline personality. Contrary to prediction, the correlation between the PPI and work ethic was not significant. Eight of 11 hypotheses regarding the relations of the PPI subscales to these 4 constructs were corroborated. Results support the construct validity of the PPI in a correctional sample. The exploratory analysis of the relation between the PPI and heroism revealed no significant relations.     

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.     

Inhibition and Disinhibition of Male Aggression Against Females: A Personality Moderator Approach

Three experiments examined the role of individual differences in combination with contextual factors hypothesized to moderate the level of hostility toward females evident in male participants' responses. In Study I, we manipulated survey context and examined the influence of participants' levels of rape myth acceptance (RMA) on self-reported rape likelihood. In Study 2, we examined the interactive role of target gender and participants' levels of sex guilt (SG) on aggression toward the target after exposure to an erotic film. Study 3 results suggested that high SG males have particularly negative responses to women (but not men) who enjoy erotic presentations, consistent with a "Jack-the-Ripper" interpretation of the Study 2 findings.     

Preliminary Evidence for Associations of CHRM2 with Substance Use and Disinhibition in Adolescence

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral disinhibition, during adolescence. The cholinergic muscarinic receptor 2 gene (CHRM2) is a promising candidate for studying genetic influences on broad-based risk for externalizing traits. This study examined a candidate CHRM2 polymorphism (rs1455858) in relation to substance use and personality measures of disinhibition in a sample of high-risk adolescents (n?=?124). Bivariate analyses and structural equation modeling (SEM) evaluated associations of rs1455858 with measures of drug involvement (alcohol, tobacco and marijuana) and disinhibition (indexed by impulsivity and sensation seeking scores). Bivariate analyses showed significant associations of CHRM2 with several behavioral phenotypes. In SEM analyses CHRM2 related significantly to latent measures of substance use and disinhibition; additionally, disinhibition mediated the association of CHRM2 with substance use. These results suggest that CHRM2 variants are potentially relevant for adolescent substance use and that temperamental risk factors could contribute to these associations.     

Elucidating the Construct Validity of the Psychopathic Personality Inventory Triarchic Scales

This study sought to replicate and extend Hall and colleagues’ (2014) work on developing and validating scales from the Psychopathic Personality Inventory (PPI) to index the triarchic psychopathy constructs of boldness, meanness, and disinhibition. This study also extended Hall et al.'s initial findings by including the PPI Revised (PPI–R). A community sample (n = 240) weighted toward subclinical psychopathy traits and a male prison sample (n = 160) were used for this study. Results indicated that PPI–Boldness, PPI–Meanness, and PPI–Disinhibition converged with other psychopathy, personality, and behavioral criteria in ways conceptually expected from the perspective of the triarchic psychopathy model, including showing very strong convergent and discriminant validity with their Triarchic Psychopathy Measure counterparts. These findings further enhance the utility of the PPI and PPI–R in measuring these constructs.     

Psychopathic Sexuality: The Thin Line Between Fantasy and Reality

In two studies, we explored the relations between psychopathic traits and sexual fantasy content. In Study 1, we rated content themes in the fantasy narratives of 195 men and women recruited at a Canadian university. In Study 2, we administered a sexual fantasy questionnaire to a sample of 355 Canadian undergraduate students. In Study 1, we found that psychopathic traits predicted themes of anonymous, uncommitted, and nonromantic sexual activity after controlling for participant sex. In Study 2, we found that psychopathy added to the prediction of self‐reported engagement in unrestricted, dominant, submissive, deviant, and adventurous sexual activity, even after controlling for participant sex and level of fantasizing about that activity. Furthermore, an interaction between psychopathy and level of fantasizing was observed for unrestricted and deviant sexual behavior, such that participants who reported high levels of fantasizing about these sexual themes were more likely to engage in that behavior if they also reported high levels of psychopathic traits. These findings suggest that psychopathy is related not only to interest in particular sexual behaviors, but also to whether individuals will translate these fantasized behaviors into reality.
