The Relationships between Five-Factor Model Personality Traits and Personality Disorder Features in an Australian Non-Clinical Sample

The aim of this study was to explore the relationships between personality traits from the Five-Factor Model (FFM) and personality disorder (PD) features in order to better understand personality disorders (PDs) from a dimensional perspective. An Australian non-clinical sample of 313 participants (M = 26.50 years, SD = 10.10, age range = 18-72 years) completed several self-report measures, including the NEO Personality Inventory-Revised and the Wisconsin Personality Disorders Inventory-IV. Correlations revealed unique and theoretically-meaningful relationships between FFM traits and PD features. Regressions clarified these relationships by identifying the most salient FFM trait predictors of PD features. These results have important theoretical and practical implications for understanding PDs from a dimensional perspective.
