title: Cross-language consistency of the Comprehensive Assessment of Psychopathic Personality (CAPP) model.
abstract: This study is the first to our knowledge to examine the cross-language consistency across the original version of the Comprehensive Assessment of Psychopathy (CAPP) and a translated version. The CAPP is a lexically based construct map of psychopathy comprising 33 symptoms from 6 broad domains of personality functioning. English-language CAPP prototypicality ratings from 124 mental health workers were compared with ratings from 211 Norwegian mental health workers using the Norwegian translation. High agreement was found across languages in regard to which symptoms where perceived as central to psychopathy or not. Multigroup confirmatory factor analyses (MGCFA) indicated that, overall, the symptoms had similar associations with the 6 proposed underlying dimensions across the 2 language versions. Finally, in general, the probability for a given prototypicality rating on an individual symptom was similar across language version samples at the same level of the underlying trait, as analyzed with Item Response Theory (IRT). Together these findings lend support to the validity of the construct of psychopathy, the validity of the CAPP as a concept map of psychopathy, and the validity of the Norwegian translation of the CAPP.
