Dimensional characteristics of DSM‐IV personality disorders in a large epidemiological sample

Abstract
Objective: To assess the five‐factor model (FFM) characteristics of young adults with Diagnostic Statistical Manual‐IV (DSM‐IV) personality disorders in a large community study. Method: As part of the eighth wave of a cohort study, 1469 young adults (mean age: 24 years) completed the NEO‐five factor inventory, 1145 of whom also had an informant‐based personality disorder assessment. Results: The prevalence of personality disorder was 18.6% (95% CI: 16.5–20.7). There were consistent positive associations with neuroticism and negative associations with agreeableness across all three clusters of personality disorder. Conclusion: In young adults, high neuroticism and low agreeableness are consistent dimensional characteristics of all personality disorder clusters.
