To provide an extended assessment of the affective features of psychopathy, Frick developed the Inventory of Callous and Unemotional Traits (ICU), which is a multi-informant questionnaire. Previous studies have provided initial support for the self-report version. The aim of the present study is to investigate the validity of self- as well as other report versions of the ICU and examine associations with measures of psychopathic traits, empathy, antisocial behavior and prosocial attitudes, reward and punishment sensitivity, and personality traits in a Dutch community sample of 455 adolescents (56% males). The results of the present study replicate and extend previous findings on the psychometric properties and the validity of the ICU in a sample of nonreferred youth. The three ICU subscales showed distinctive patterns of associations with key external criteria. Implications and directions for future research are discussed.

The study examined the reliability and validity of the Antisocial Process Screening Device (APSD) and the Childhood Psychopathy Scale (CPS) in a community sample of 182 Flemish adolescents in the age range of 9 to 19 years. Data were gathered by means of parent, teacher, and self-report, and the factor structure was examined by means of confirmatory factor analysis. Internal consistencies of the resulting scales and associations with measures of disruptive behavior disorders and internalizing problem behaviors were explored. Results confirmed the underlying a priori structure of both APSD and CPS.
