N2 - 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.
