Factor structure of the Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR) in community and...

The Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR) is a recent operationalization of the CAPP model, which conceptualizes psychopathy in terms of 33 symptoms that can be thematically organized according to six theoretical domains. The current study examined the higher order factor structure of the CAPP-SR symptom scales in community, university, and offender samples derived from three separate countries. Exploratory factor analysis (EFA) indicated that a three-factor model (Antagonism/Meanness, Disinhibition, and Fearless Grandiosity) was optimal in a large population-representative U.S. community sample. EFA with targeted rotation confirmed this three-factor structure in New Zealand university and Lithuanian prison samples. Furthermore, construct validity analyses against other psychopathy measures and psychopathy-relevant criteria provided initial support for the three CAPP-SR latent factors. For instance, CAPP-SR Antagonism/Meanness was associated with other psychopathy scales reflective of antagonism, meanness, callous affect; CAPP-SR Disinhibition with other psychopathy scales reflective of behavioral psychopathy traits (e.g., impulsivity, irresponsibility), antisocial behavior, substance abuse; and CAPP-SR Fearless Grandiosity with narcissism, emotional stability, and boldness. These findings suggest that a three-factor structure provides for an alternative (to the traditional thematic domains) hierarchical interpretation of CAPP-SR scores.
