This study evaluated the psychometric properties of the Turkish version (PID-5-SF-TR) in a sample of 349 adolescents (181 community, 168 clinical). Participants also completed the Personality Belief Questionnaire-Short Form (PBQ-SF) and the Big Five Inventory (BFI). Clinical participants had higher facet scores than community participants. Exploratory factor analysis revealed a five-factor structure for both groups. Cronbach's alpha coefficients ranged from 0.72 to 0.86 in the clinical group and from 0.73 to 0.87 in the community group. PID-5-SF-TR domains correlated significantly with related BFI dimensions, except for Openness and Psychoticism. Corresponding PBQ-SF and PID-5-SF-TR subscales were significantly correlated. Test-retest reliability over 5 months showed coefficients ranging from r = 0.30 to r = 0.67. Findings support the reliability and validity of using the PID-5-SF-TR when diagnosingTurkish adolescents.eninfo:eu-repo/semantics/closedAccessAdolescentMaladaptive Personality TraitsValidityAlternative Model for Personality DisordersPersonality Inventory for DSM-5-Short FormReliabilityArticle10.1521/pedi.2026.40.1.482-s2.0-105030414872
