Abstract

The psychometric properties of the self-report version of the Antisocial Processes Screening Device (APSD; Frick & Hare, 2001), a rating scale developed to assess traits associated with the construct of psychopathy in youth, was tested in a sample of 91 non-referred young adolescents with an average age of 13.38 (SD = 1.75) at the initial assessment. The sample was recruited from a large community-wide screening, where youth with conduct problems and youth high on psychopathic traits were over-sampled. The sample was reassessed three times at yearly intervals. The self-report scores on the APSD showed moderate correlations with parent ratings of psychopathic traits, were moderately stable across 1–2 years, and showed significant correlations with measures of antisocial behavior both concurrently and predictively. One major weakness of the self-report ratings was the low internal consistency of the subscales, which were much lower than the internal consistency found on the parent report version of the scale.
