A prototypicality validation of the Comprehensive Assessment of Psychopathic Personality model (CAPP).
Cooke and colleagues recently developed the lexically based model of psychopathy named the Comprehensive Assessment of Psychopathic Personality (CAPP, Cooke, Hart, Logan, & Michie, 2004). The current study was the first to evaluate aspects of the validity of a translated version of the CAPP model, which comprises 33 symptoms from six domains of personality functioning. Prototypicality ratings from 796 Norwegian community residents, forensic mental health professionals, and corrections professionals were obtained. Most CAPP symptoms were evaluated as highly prototypical of psychopathy by all three groups. Symptoms from the Self, Dominance, and Attachment domains were perceived as more prototypical than those from the Behavioral domain. Confirmatory Factor Analysis (CFA) indicated that two CAPP domains were unidimensional whereas evidence of unidimensionality was somewhat weaker for the other domains, but improved substantially after removal of problematic symptoms. Overall, the findings support the content validity of the CAPP model. This may have relevance to the current considerations regarding reformulation of the criteria for Antisocial Personality Disorder in DSM-V.
