The antisocial process screening device: an examination of its construct and criterion-related validity.

The clinical assessment of psychopathy in adulthood is well established via programmatic research. More recently, psychopathy has been extended to children and adolescents with correlates to maladaptive personality traits, violent behavior, and noncompliance with institutional rules. To screen for adolescent psychopathy, the Antisocial Process Screening Device (APSD) was developed as a 20-item self-report measure of psychopathy. The original validation of the APSD was limited to samples of clinic-referred and community-based children. In extending this research to delinquent populations, the current article uses two separate samples of adolescent offenders incarcerated in a maximum security facility (n = 78) and a local juvenile detention facility (n = 77). As evidence of criterion-related validity, the APSD was compared with two versions of the Psychopathy Checklist that yielded mixed results. Construct validity was examined via a confirmatory factor analysis that provided support for a three-factor model of the APSD.
