Brief report: Self-reported psychopathic-like features among Finnish community youth: Investigation of the factor structure of the antisocial personality screening device

The Antisocial Process Screening Device- Self-Report (APSD-SR) is a self-report measure for assessment of psychopathic traits in adolescents. The present study aimed to investigate the factor structure and internal consistency of the APSD-SR in a sample of 4855 Finnish community adolescents. A three-factor structure with factors representing impulsivity (IMP), narcissism (NAR) and callous-unemotional (CU) features was found. Internal consistency indices ranged from moderate to good. The findings provide promising data on applicability of the APSD-SR instrument to Scandinavian youth. Results have implications for researchers and clinicians interested in measuring adolescent psychopathy.
