- 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.

- This study aimed to test the predictive and incremental value of psychopathic trait dimensions in early childhood. To this end, a callous-unemotional (CU)-based approach was compared to the multidimensional psychopathic personality approach in predicting future and stable conduct problems (CP) and aggression, whilst controlling for well-established risk factors for child CP. Prospective longitudinal data were collected from a community sample of 2247 children (48.6% girls) aged three to six (Mage = 4.25; SD = 0.91) at the initial assessment. Participants were followed annually for two years, with information provided by parents. Children were assigned to six mutually exclusive groups based on their baseline levels of psychopathic traits and conduct problems. Results showed that, after accounting for sociodemographic variables, temperamental features (e.g., fearlessness), and ADHD symptoms, children scoring high in all psychopathic traits and high in CP were at increased risk to display future and stable CP, reactive and proactive aggression, followed by the group of children high in CU traits and CP. Future research on child psychopathy may benefit from considering the constellation of co-occurring interpersonal, affective and behavioral psychopathic traits, and could inform developmental models aiming to explain heterogeneity in child CP.

- Various imaging techniques as well as parasympathetic and sympathetic nervous system measurement methods have allowed for the increasingly sophisticated investigation of the psychophysiology that underlies the psychopathic personality and its dimensions including Conduct Disorder. With this special section, we were interested in whether the dimensions separately tell us anything different regarding the underlying mechanisms or processes involved in the specific phenotypic expression(s) of psychopathy. Seven empirical articles address this question by examining the psychobiology of psychopathy from a multicomponent perspective. Four articles examined the heart functioning and/or skin conductance of those with elevated psychopathic traits and two studies used EEG to index and image the brain. A single study tested heart functioning in relation to the environment. Findings from the papers indicate differences with respect to psychophysiology across the dimensions and thus signal benefits to examining the broader construct of psychopathy as well as its underpinning dimensions. Those with elevated GM traits appear to have aberrations with respect to self-referential processing and fealessness in adulthood but limited impairments otherwise, whereas those with elevated CU and DI traits show impairment in associative learning and potentially fear processing and arousal. Findings from the special section articles may have implications for the etiology, treatment, and eventually diagnostic manuals (i.e., DSM-5, ICD-11). We hope that these studies in this special section lead to additional multicomponent investigations that ultimately improve our understanding of the psychobiological mechanisms of psychopathy.

Psychopathic personality, and its dimensions in the prediction of negative outcomes : Do they offer incremental value above and beyond common risk factors? Introduction to the special section

- A total of nine studies put the psychopathy construct to a stringent test by examining the predictive ability while controlling for common risk factors for negative outcomes. In this way, the special section studies shed light on the important issue as to whether psychopathy as a construct offers something above and beyond common risk factors. Eight of the nine studies showed in different ways, in different countries, with different developmental/ age periods, and with different measures and conceptualizations that psychopathic personality often was pre-dictive of negative outcomes after adjusting for common risk variables. Five studies examined the association between psychopathic personality and negative outcomes in young children. All five of these studies found psychopathic personality to be predictive above and beyond common risk factors. Three studies examined psychopathy and its relation to negative outcomes from adolescence forward. Two of the three studies in this age band found psychopathy to be predictive of negative outcomes after controlling for common risk factors. Finally, one study examined psychopathy from adulthood forward in a specialized population and found that Factor 2 of the PCL-R was predictive of recidivism above and beyond the commonly used DSM diagnosis of ASPD. These findings support the notion that individuals with psychopathic personality follow a hazardous course impacting their own well-being as well as negatively impacting society. The implications of the findings are discussed in further detail and directions for future research are considered.
