The Factor Structure and Age-Related Factorial Invariance of the Delis-Kaplan Executive Function System (D-KEFS)

There has been an increased interest in the structure of and relations among executive functions.The present study examined the factor structure as well as age-related factorial invariance of the Delis—Kaplan Executive Function System (D-KEFS), a widely used inventory aimed at assessing executive functions. Analyses were first conducted using data provided in the D-KEFS technical manual and were then replicated in an independent sample of male early adolescents aged 11 to 16 years. Results revealed a three-factor solution best fit the data across groups and samples; measurement properties appeared to be invariant across age groups for certain loadings and variant for others. The three factors were labeled Conceptual Flexibility, Monitoring, and Inhibition. These findings provide better understanding of the measurement properties of the D-KEFS and contribute to the larger literature on the structure of measures intended to assess executive functions.

Exploring Callous and Unemotional Traits in Youth via General Personality Traits: An Eye Toward DSM-5

The current study aimed at better understanding callous-unemotional (CU) traits in youth within a traditional personality trait/temperament framework as well as in relation to current proposals for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Participants were 174 mothers and their sons age 11-16 years. Mothers and youth reported on youth CU traits and general personality trait/ temperament dimensions. Overall, analyses revealed significant unique associations of personality trait/temperament dimensions with CU total and subscale scores. Personality trait/temperament dimensions explained 36% to 58% of the variance in CU subscales and total score. Furthermore, specific personality dimensions differentially and uniquely predicted various CU subscales, indicating marked specificity in association such that these traits should be considered separately rather than as a single unit. Taken together, these results confirm the importance of considering traditional personality trait models to understand callous and unemotional traits and risk for psychopathy more fully. Additionally, our findings bear implications for the conceptualization and operationalization of these traits in DSM-5.

Examining the correlates of the coldheartedness factor of the Psychopathic Personality Inventory-Revised.

Coldheartedness is a subscale of the Psychopathic Personality Inventory-Revised (PPI-R) that does not load onto either of the PPI-Rs two traditional higher order factors (Fearless Dominance [FD] and Self-Centered Impulsivity [SCI]). As a result, it has been omitted from analyses in many studies. However, owing to Coldheartednesss associations with lack of empathy, guilt, and deep-seated social emotions, this subscale may be highly relevant to the construct of psychopathy. In a sample of 1,158 undergraduates, we attempted to clarify Coldheartednesss correlates within the context of a nomological network of psychopathology and personality; in addition, we examined Coldheartednesss contributions to psychopathy above and beyond FD and SCI. Coldheartedness demonstrated negative correlations with the Big Five personality factors, mixed correlations with indices of impulsivity, and largely negative correlations with measures of depression and anxiety. Regressions suggested that Coldheartedness displays substantial overlap with both FD and SCI but also contains psychologically important unique variance. Although the nature of this variance requires clarification, further research and perhaps an expansion of the Coldheartedness subscale may move the field toward a clearer understanding of the construct assessed by this measure.

Parsing the Heterogeneity of Psychopathy and Aggression: Differential Associations Across Dimensions and Gender

Psychopathy is a multidimensional construct that is broadly associated with both reactive (RA) and proactive (PA) aggression. Nevertheless, a consistent pattern of associations between psychopathy and these 2 aggression subtypes has yet to emerge because of methodological differences across studies. Moreover, research has yet to examine gender differences in the relation between dimensions of psychopathy and RA/PA. Accordingly, we examined the associations between psychopathy dimensions, as operationalized by 2 self-report instruments, and subtypes of aggression within a diverse sample of undergraduates (N = 1,158). Results confirmed that psychopathy is broadly associated with PA, as well as RA, with dimensions of psychopathy evidencing common and distinct associations with both raw and residual RA and PA scores. In both models of psychopathy, PA was significantly and positively associated with all dimensions, whereas RA was significantly negatively associated with interpersonal and affective dimensions, and significantly positively associated with dimensions related to an antisocial and impulsive lifestyle. Gender significantly moderated associations among dimensions of psychopathy and RA/PA, such that the antisocial/behavioral dimension of psychopathy was positively associated with PA for males, whereas the antisocial/behavioral dimension was positively associated with RA for females. Results suggest both generality and specificity of psychopathy dimensions as related to subtypes of aggression, as well as possible differential pathways from psychopathy to different subtypes of aggression in men and women.

Personality Disorder Features and Paraphilic Interests Among Undergraduates: Differential Relations and Potential Antecedents

We examined the relations between: (1) narcissism, psychopathy, DSM-5 personality disorder symptom counts; and (2) paraphilic interests among undergraduates (N = 608). Base rates of paraphilic interests were appreciable. The disinhibition and meanness features of psychopathy and the entitlement and exploitativeness features of narcissism were robustly associated with paraphilic interests, particularly sexual sadism, whereas the boldness features of narcissism and psychopathy were essentially unrelated to these interests. Narcissism and psychopathy features typically manifested the most pronounced relations with paraphilic interests, although antisocial personality disorder features were also strong predictors. By and large, these relations were comparable across gender. Lastly, there was no evidence that erotophilia mediated the relations between the narcissism and psychopathy features and paraphilic interests, most likely because erotophilia was generally unrelated to paraphilic interests. Relative to other dimensions of personality disorders, facets of meanness and disinhibition from psychopathy and entitlement/exploitativeness facets from narcissism were most associated with paraphilic interests.
