title: A psychometric study of DSM-IV passive-aggressive (negativistic) personality disorder criteria.
abstract: The passive-aggressive (negativistic) personality disorder (PAPD) is one of the most controversial personality disorders. In order to assess DSM-IV PAPD psychometric properties and comorbidity pattern in a mixed psychiatric sample, 379 consecutively admitted in- and outpatients were administered SCID-II, Version 2.0. Confirmatory factor analysis showed that DSM-IV PAPD is a unidimensional construct with adequate internal consistency (K-R 20 = .85). A strong, specific association (odds ratio = 10.38, 95% CI = 4.83-22.30) was observed between DSM-IV PAPD and narcissistic personality disorder (NPD). Confirmatory factor analysis showed that DSM-IV PAPD should be considered as a subtype of a broader narcissistic disorder.
