This study examined the structure, distribution, and correlates of a new measure of self-reported callous-unemotional (CU) traits in 1,443 adolescents (774 boys, 669 girls) between the ages of 13 to 18 years. The Inventory of Callous-Unemotional Traits was subjected to exploratory factor analysis and confirmatory factor analysis. Exploratory factor analysis produced three factors: callousness, ...

Children who exhibit callous-unemotional (CU) traits are identified as developing particularly severe forms of externalising behaviours (EB). A number of risk factors have been identified in the development of CU traits, including biological, physiological, and genetic factors. However, prenatal testosterone (PT) remains un-investigated, yet could signal fetal programming of a combination of CU...

The main aim of the present study was to specify and test a structural model to examine the relationships between four psychopathy dimensions (Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Antisocial Behavior), childhood exposure to violence, and rape myth acceptance while controlling for gender, age, sample type (prisoner vs. non-prisoner), and relationship status. Partici...

The aim of the present study was to analyze the relevance of the DSM-5's Conduct Disorder new Limited Prosocial Emotions (CD LPE) specifier in incarcerated juvenile delinquents. A sample of 201 males and 98 females from the Juvenile Detention Centers managed by the Portuguese Ministry of Justice diagnosed with Conduct Disorder (CD) was used.

The current study assesses the factor structure and construct validity of the self-reported Inventory of Callous-Unemotional Traits (ICU) in 637 Chinese community adults (mean age = 25.98, SD = 5.79). A series of theoretical models proposed in previous studies were tested through confirmatory factor analyses. Results indicated that a shortened form that consists of 11 items (ICU-11) to assess c...

The current study investigated the relation of callous-unemotional (CU) traits to bullying, victimization, and proactive and reactive aggression. We also examined whether CU traits will be more strongly related to groups of children exhibiting combined or pure forms of proactive and reactive aggression and combined or pure forms of bullying and victimization. The findings suggested that the pre...

Although knowing and feeling the emotions of other people might result in less bullying, we argue that not caring about these feelings will also be important. That is, what good is empathy, if one does not care about the feelings or values of others? We examined self-reports of callous-unemotional traits (CU: Inventory of Callous-Unemotional Traits), bullying, and empathy in 201 children (ages ...
