Coverage of the DSM-IV-TR/DSM-5 Section II Personality Disorders With the DSM-5 Dimensional Trait Model

Section III of DSM-5, for emerging measures and models, includes a five-domain, 25-trait model, assessed by the Personality Inventory for DSM-5. A primary concern with respect to the trait model is its coverage of the DSM-IV-TR personality disorder syndromes (all of which were retained in DSM-5). The current study considered not only total scale scores of three independent measures of DSM-IV-TR personality disorders but also the coverage of each diagnostic criterion included within six personality disorders: antisocial, borderline, avoidant, dependent, narcissistic, and obsessive-compulsive. Participants were 425 community adults, all of whom had received mental health treatment (36% currently; 75% within the past year). Results provided support for the coverage of the diagnostic criteria for the antisocial, borderline, avoidant, dependent, and narcissistic personality disorders. Coverage could perhaps be improved for a few of the criteria for obsessive-compulsive personality disorder.
