Abstract
Background: The dimensional approaches to personality disorders proposed in ICD-11 and DSM-5 were developed to address limitations of traditional categorical classifications. Despite growing interest in these models, cross-cultural evidence from non-Western populations remains limited.
Methods: The present study examined the psychometric characteristics of the Personality Inventory for ICD-11 (PiCD) and evaluated its associations with external variables in comparison with the Personality Inventory for DSM-5–Brief Form (PID-5-BF) within an Iranian sample. Participants included 347 university students from Tehran (61.9% female), consisting of 206 non-clinical and 141 help-seeking individuals. Participants completed the PiCD, PID-5-BF, BFI-10, LPFS-BF 2.0, SCL-25, BIS-11, and CAB. Confirmatory factor analysis (CFA), correlation analyses, and hierarchical regression analyses were conducted.
Results: The PiCD showed satisfactory internal consistency, with Cronbach’s alpha and McDonald’s omega coefficients across domains. CFA supported the five-factor structure of the PiCD after removal of four items, showing acceptable fit indices (CMIN/df = 1.44, RMSEA = .036, CFI = .90). PiCD domains were significantly associated with personality dysfunction, psychological distress, impulsivity, and externalizing behaviors. Negative Affectivity showed the strongest associations with anxiety, depression, and overall symptom severity, whereas Disinhibition was most strongly related to impulsivity and externalizing behaviors. Hierarchical regression analyses indicated that PiCD domains explained substantial variance in personality functioning, anxiety, depression, impulsivity, and criminal behavior. Overall, PiCD and PID-5-BF demonstrated broadly similar correlational patterns with external measures.
Conclusions: The results offer preliminary evidence for the reliability, structural validity, and cross-cultural relevance of the ICD-11 dimensional personality trait model within an Iranian population. The findings also indicate substantial overlap between the ICD-11 and DSM-5 dimensional frameworks in the assessment of maladaptive personality traits and associated psychopathological features.
