To date, numerous studies have confirmed empirical relevance of the personality trait model defined in the Alternative DSM‐5 Model for Personality Disorders. The supposed single‐factor structure of its facets and general domains across various samples, however, has not been researched thoroughly. This study focused on evaluating the hypothesized unidimensional factor structure of the lower‐order personality trait facets, as well as the validity of the higher‐order domains. The Czech version of the Personality Inventory for DSM‐5 (PID‐5) was used in a sample of 351 community volunteers and 143 psychiatric patients. The fit of the model for 25 facets could not be replicated with the original PID‐5, while a shortened version confirmed the single‐factor structure of all facets and their relevance to the five proposed domains. The findings support unidimensional structure of the modified DSM‐5 personality trait model and imply discussion of the utility of the proposed PID‐5 version. Copyright © 2018 John Wiley & Sons, Ltd.
