Abstract The classical nosographical approach to personality disorders leads to a set of categories that may be considered to be both conceptually and empirically problematic. In this regard, the DSM-5 includes an alternative dimensional model for which the Personality Inventory Disorders (PID-5) has been developed. Our study compares this alternative dimensional model in regards to both personality disorder categories and normal personality dimensions. The 537 participants in our study, 65.4% of whom were women, completed both the PID-5 and the International Personality Disorder Examination (IPDE) screening questionnaire. Among these participants, 273 participants (64.1% women) also completed the revised version of the NEO Five-Factor Inventory (NEO-FFI-R). A multiple factor analysis indicated that two higher-order principal dimensions described the relationships between the PID-5 and both the IPDE and the NEO-FFI-R. These relationships were analyzed in greater detail using a Principal Axis Factor Analysis. Five and four, respectively, intercorrelated lower-level factors were considered after a parallel analysis that confirmed to a certain extent that normal and abnormal personalities share a common underlying structure. Finally, a multiple regression bootstrap series confirmed the close associations between the PID-5 and both the IPDE and the NEO-FFI-R scales. Our results indicate that the PID-5 offers an alternative perspective for describing symptom syndromes with personality pathology.
