BACKGROUND: The psychopathology of personality is currently undergoing a paradigm shift from a categorical to a dimensional approach. This work aimed to study the underlying structure of pathological personality traits of the DSM-5 Alternative Model for Personality Disorders (AMPD). For this purpose, the internal structure of a version of the Personality Inventory for the DSM-5 [PID-5] was examined by a Confirmatory Factor Analysis. This version assesses the five higher-order pathological personality domains (Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism) and the 25 lower-order pathological personality facets through a reduced number of items. Four alternative models were compared: five-factor oblique; second-order (five first-order factors and one second-order factor); bifactor (five specific factors and a general factor), and one-factor. PARTICIPANTS AND PROCEDURE: We worked with an Argentinean sample of n= 525 subjects from the general population who answered the Argentine version of the PID-5. RESULTS: The five-factor model was slightly superior to the second order model, and the bifactor model presented the best fit. CONCLUSIONS: These findings, while preliminary, suggest that the PID-5 facets could reflect five specific pathological personality traits (which correspond to AMPD domains) but also a general factor (which would reflect a general propensity for psychopathology).
