title: Generality of Psychopathy Checklist-Revised factors over prisoners and substance-dependent patients.
abstract: The Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991) is an often-used device for assessment of adult antisociality. This research examined generalizability by replicating the 2-factor model for a sample of 326 male prisoners and assessing its congruence and relative reliability and specificity among 620 substance-dependent patients. Generality was assessed also across addiction subtypes (opioid, cocaine, and alcohol), age, gender, and ethnicity. The 2-factor model was found inappropriate for the substance-dependent samples, whereas a unidimensional model represented by the PCL-R total score was found generalizable across prison and substance-dependent samples.
