Aim Personality disorders (PD) have been deemed the most problematic diagnostic grouping in terms of validity and utility, which particularly applies to non‐Western societies. The current study evaluated the structural validity of PD trait domains in the Diagnostic and Statistical Manual of Mental Disorders‐5 (DSM‐5) Section III and the proposed International Classification of Diseases‐11 (ICD‐11) in the Iranian population. Methods Community‐dwelling adults ( n = 285; 66% women) were administered the Personality Inventory for DSM‐5, whereas the proposed ICD‐11 trait domains were delineated using an algorithm for Personality Inventory for DSM‐5 trait facets. The five‐factor organization and higher‐order hierarchical structure of both models were examined using exploratory structural equation modelling analyses. Results The five‐factor exploratory structural equation modelling loadings overall resembled international findings on DSM‐5 Section III traits (including Psychoticism), whereas the ICD‐11 five‐factor structure aligned with the proposed ICD‐11 domain features (including Anankastia). Additionally, we identified a hierarchical structure from one to five factors for both models that conceptually aligned with established models of personality and psychopathology. Conclusions This study provided initial support for the structural validity of DSM‐5 and ICD‐11 PD trait models in Iranian culture. Future research warrants replication in larger samples and clinical populations. Copyright © 2018 John Wiley & Sons, Ltd.
