Categorically-based systems for assessing personality disorders (PDs) have been criticized on a number of grounds, including arbitrary cutoffs for diagnosis, heterogeneity among presentations of the same PD, overuse of PD not otherwise specified, and high comorbidity, both among different PDs, and between PDs and other types of mental disorders. The present study sought to validate the Personality Disorder for DSM-5 (PID-5), a trait-based model for assessing personality disorders. The sample consisted of 212 undergraduates and community members recruited to over-represent individuals with high and low trait fear as well as high and low trait disinhibition. Self-reported PID-5 trait scores were correlated with clinician-rated interview-based personality disorder symptoms. Personality traits specified in Section III of the DSM-5 provided excellent representation of Antisocial PD, Borderline PD, and Avoidant PD interview-based symptoms, moderate representation of Obsessive-Compulsive PD symptoms, and minimal representation of Narcissistic PD symptoms. Further traits were identified as relevant to PDs without representation in the DSM. Additionally, results indicated that the recruitment strategy augmented the base rates of Cluster B and Cluster C PDs in the sample.
