Construct Validity of the Comprehensive Assessment of Psychopathic Personality - Self-Report Form (CAPP-SR)

The Comprehensive Assessment of Psychopathic Personality (CAPP) is a concept map developed to consolidate research on psychopathy. Recently, the CAPP - Self Report form (CAPP-SR) was developed, but its psychometric properties have not been extensively or independently investigated. The current study evaluated the internal consistency, factorial structure, and construct validity of the CAPP-SR in a large sample of undergraduate and community participants. No organizational structure was superior, but a theoretically supported three factor solution representing behavioral, affective, and interpersonal traits appeared to be the optimal solution. The CAPP-SR demonstrated overlap with other preexisting psychopathy measures and the three-factor solution evinced relatively good convergent and discriminant associations with external criteria. The CAPP-SR seems to measure a similar construct to psychopathy measures, though it remains unclear whether the new measure captures meaningful information neglected by other models or outperforms them in prediction of important outcomes.
