Domains of psychopathy: evaluating the structure of a lexical model of psychopathic personality disorder.

This study examines the structure of the Comprehensive Assessment of Psychopathic Personality (CAPP) from a card sort perspective. The CAPP is a lexically based construct map of psychopathy comprising 33 symptoms organized by its developers into 6 broad functional domains of personality (i.e., Attachment, Behavioral, Cognitive; Dominance; Emotional, Self). Groups of mental health workers and students were asked to sort the CAPP symptoms into the model's 6 proposed domains. Overall, both mental health workers and students were able to categorize the symptoms speedily and intuitively according to model. This suggests that the CAPP model's hierarchical structure is plausible, and that the lexical nature of the model is successful in facilitating people's ability to understand features of psychopathy in a way that requires limited cognitive effort. Together, these findings support the validity of the CAPP model as a lexically based concept map of psychopathy. Yet, some exceptions to the overall pattern of agreement with model were identified.
