Prototypicality analysis of the Comprehensive Assessment of Psychopathic Personality (CAPP): A cross-cultural perspective

The Comprehensive Assessment of Psychopathic Personality (CAPP) model is a new lexically based concept of psychopathy that has potential clinical utility. The main purpose of this research is to investigate the generalizability of the CAPP conceptual model in South Korea. In the current study, 88 experts and 1727 laypeople in South Korea were asked to evaluate the prototypicality of the symptoms of psychopathy (CAPP items) by using a Korean translation of the CAPP model (K-CAPP). In addition, 11 international prototypicality studies were systematically compared to the ratings by experts in the present study. As a result, it indicated that Korean experts and laypeople, on average, rated K-CAPP symptoms as moderately to highly prototypical of psychopathy, and more prototypical of psychopathy than symptoms theoretically unrelated to psychopathy (foils). Also, prototypicality ratings of K-CAPP symptoms made by those two groups were similar to each other as well as to ratings by experts and laypeople using the CAPP in other 11 countries. In conclusion, these results clearly show that both experts and laypeople in the current study conceptualized PPD in almost the same way as experts and laypeople from previous studies using the CAPP model.
