Studying Configurations of Psychopathic Traits: Exploring the Viability of Psychopathic Personality in Early Childhood

Gender Differences in Co-developmental Trajectories of Internalizing and Externalizing Problems: A 7-Year Longitudinal Study from Ages 3 to 12

The co-occurrence of externalizing and internalizing problems is acknowledged, but gender differences remain unclear. The present study examines gender differences in the longitudinal relationships between conduct and emotional problems throughout childhood. The sample, drawn from the ELISA project, included 2368 children (48.1% girls; ages 3-12). Latent growth curve models were employed to analyze the trajectories of parent-reported conduct problems and emotional symptoms separately, while parallel process latent growth curve models were utilized to compare joint trajectories. The decrease in conduct problems was consistent for girls, but not for boys. High initial emotional symptoms predicted a slower increase in emotional symptoms over time for girls. Parental positivity was a protective factor for conduct problems in girls. Grandiose-deceitful traits were more related to conduct problems in girls, while callous-unemotional traits were related to emotional symptoms in boys. This study highlights the importance of considering gender in childhood conduct and emotional problems.

Proposed Specifiers for Conduct Disorder (PSCD) scale: A Latent Profile Analysis with At-Risk Adolescents

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin in Pers Disord: Theory Res Treat 7:180-191, 2016) scale was designed to assess interrelated psychopathic trait domains in conjunction with symptoms of Conduct Disorder (CD) in children and adolescents (i.e., grandiose-manipulative, callous-unemotional, daring-impulsive). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985-992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9% White, 20.1% Black, 3.6% Hispanic, and 5.4% other) of adolescents (modal age = 17) in a military style residential facility (N = 409; Males = 80.6%). As hypothesized, a four-class solution was best, consistent with adult psychopathy subtyping research (Hare et al. in Handbook of Psychopathy 39-79, 2018; Roy et al. in Pers Disord: Theory Res Treat, in press). The PSCD subtype profiles were uniform across sex and race/ethnicity. Adolescents evincing a psychopathic trait propensity profile (elevated on all four PSCD domains) displayed the greatest number of arrests and higher overall externalizing psychopathology, compared to the other three latent classes, as well as higher internalizing psychopathology compared to adolescents with general delinquency. The PSCD provides a sound measure of psychopathic trait propensities in youth and our results offer investigators and clinicians a means for understanding person-centered psychopathic traits versus antisocial profiles among at-risk adolescents. Taken together, the current results may offer a viable approach for examining specific treatment targets based on PSCD subtype profiles.

Emotion Recognition Deficits in Children and Adolescents with Psychopathic Traits: A Systematic Review

Children and adolescents with psychopathic traits show deficits in emotion recognition, but there is no consensus as to the extent of their generalizability or about the variables that may be moderating the process. The present Systematic Review brings together the existing scientific corpus on the subject and attempts to answer these questions through an exhaustive review of the existing literature according to PRISMA 2020 statement. Results confirmed the existence of pervasive deficits in emotion recognition and, more specifically, on distress emotions (e.g., fear), a deficit that transcends all modalities of emotion presentation and all emotional stimuli used. Moreover, they supported the key role of attention to relevant areas that provide emotional cues (e.g., eye-region) and point out differences according to the presence of disruptive behavior and based on the psychopathy dimension examined. This evidence could advance the current knowledge on developmental models of psychopathic traits. Yet, homogenization of the conditions of research in this area should be prioritized to be able to draw more robust and generalizable conclusions.

Proposed Specifiers for Conduct Disorder (PSCD) self-report: Factor structure and validation in a community sample of Belgian youth

The current study examined the psychometric properties of the Proposed Specifiers for Conduct Disorder (PSCD) in a sample of school-attending adolescent Belgian youth (N = 599; M age = 16.51 years, SD = 1.27). Given the recent interest in the PSCD-Short Version (PSCD-SV), this study focused on the 13-item variant of the PSCD. Study findings showed that the PSCD-SV had a hierarchical four-factor structure including the components of grandiose-manipulative (GM), callous-unemotional (CU), daring-impulsive (DI), and conduct disorder (CD). These interrelated factors were found to be internally consistent. The study also showed that the PSCD-SV total score was positively and significantly related to an alternate measure of psychopathy. Further, the study revealed the PSCD-SV was meaningfully related to the five-factor personality domains (i.e., extraversion, conscientiousness, agreeableness) as well as peer functioning and prosocial behavior. Bivariate correlations demonstrated that the dimensions differed in their associations with external correlates (e.g., peer functioning). Regression analyses showed that the GM, CU, and CD components of the PSCD-SV were uniquely associated to externalizing difficulties, whereas only the GM and CU components of the PSCD-SV were associated with low prosocial behaviors. These findings shed light on the conceptual and developmental models for the consideration of psychopathy and conduct problems. The use of the broader psychopathy condition as well as its underpinning dimensions may have important implications for assessment, treatment, and diagnostic manuals. The implications of the current study are further discussed.

In Search of Conceptual Clarity About the Structure of Psychopathic Traits in Children: A Network-Based Proposal

Psychopathic traits in childhood have been revealed as potential identifiers of risk, being predictive of later forms of behavioral maladjustment. Yet, it is still under debate how psychopathic traits in children should be best conceptualized and which are the core dimensions for construct definition and prediction. The present study aims to examine the structure of psychopathic traits in childhood, and its predictive value, by using a combination of traditional factor analysis and more recent network-based methods. Data on psychopathic traits, as measured by the Child Problematic Traits Inventory (CPTI), were collected in a large sample of children (n = 2454; 48.2% girls), aged 3 to 6 at the onset of the study (Mage = 4.26; SD = 0.91), who were followed-up one and two years later using parent- and teacher-reports. Results showed that psychopathic traits measured via CPTI are best conceptualized as five latent factors encompassing grandiosity, deceitfulness, callousness, impulsivity and need of stimulation, a result that converged across informants and time. Callousness and grandiosity emerged as central traits using network analysis of parent-reports, while deceitfulness was most central using teacher-reports. Finally, callousness, impulsivity and deceitfulness emerged as the best predictors of concurrent, prospective and stable conduct problems. These results provide a refined structure of psychopathic traits in children that better accounts for the core elements of the construct. Additional theoretical and practical implications will be discussed in terms of assessment, diagnostic classification and tailored prevention/intervention.

Psychopathic Personality Configurations in Early Childhood: A Response to Dvoskin et al. (2022)

Dvoskin et al. (2022) offered a cautionary comment on an article published in the Journal of Personality Disorders (López-Romero et al., 2021). This comment was focused on the scientific and policy grounds of our study, and cautioned against the use of the "putative psychopathic personality" label for applied purposes. While we agree with most of their concerns and cautions, we aim to provide additional clarification on the raised concerns, noting that the purpose of our study is purely exploratory, and that its findings are not intended for applied purposes. We do expect that our study and this commentary will further clarify the importance of examining psychopathic personality from a developmental perspective, opening new ways of discussion regarding how to best conceptualize and study a construct that, while waiting for additional longitudinal research, has been shown as relevant in identifying a group of children and adolescents at increased risk for maladjustment.

Psychopathic Personality in Early Childhood: A Critical Comment on Lopez-Romero et al. (2021)

A recent article published in the Journal of Personality Disorders (López-Romero et al., 2021) described the identification of "putative psychopathic personality" in a school cohort of 3-6-year-old children from Spain. This comment offers cautionary considerations of the original article on scientific grounds and critical comments on policy grounds. We caution researchers, policymakers, attorneys, judges, and the general public about the dangers of using this label given present knowledge about the antecedents, early indicators, and stability of the adult disorder of psychopathic personality when assessed in childhood.
