Abstract

The present research tested the four-factor Psychopathy Checklist: Screening Version (PCL:SV) latent variable model for structural invariance across ethnicity in a large sample of civil psychiatric patients. In addition, it also examined how Barratt (1994) impulsivity and Novaco (1994) anger latent variables were related to the psychopathy dimensions within and across ethnicity. The data were analyzed with Mplus (Muthen & Muthen, 2001), and results indicated that the four-factor model was invariant across Caucasian and African American males in terms of both item factor loadings and thresholds. However, differential relations between the external correlates and the psychopathy dimensions were found across groups, suggesting that the association between impulsivity and psychopathy may be moderated by ethnicity.
