Abstract
Background: There is considerable debate about the underlying factor structure of the Psychopathy Checklist: Screening Version (PCL: SV). An established view is that it reflects a unitary construct underpinned by two correlated factors. More recent research has, however, undermined this conceptualisation.
Aims: Our aim was to compare 10 competing models of the PCL: SV in a sample of civil psychiatric patients. Method: Ten distinct factor models were specified and tested using conventional confirmatory factor analytic techniques, along with confirmatory bifactor modelling. Results: A bifactor model, including two general factors (interpersonal-affective and antisocial-lifestyle), and four subordinate factors (interpersonal, affective, antisocial, and lifestyle) provided the best fit to the data. The reliability of the conceptualisation was supported through the use of composite reliability, and the differential relationships exhibited between the general factors and measures of personality, impulsivity, and mental health. Conclusions: The results suggest that two general factors should be taken into account when interpreting the PCL:SV for clinical purposes.
