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.
