Abstract

This study examined the validity of the borderline construct which encompasses diagnostic criteria from the DSM-IV-TR Borderline Personality Disorder (BPD), ICD-10 Emotionally Unstable Personality Disorder (EUPD), and CCMD-III Impulsive Personality Disorder (IPD) in a sample of 1,419 Chinese psychiatric patients. Participants completed the Chinese Personality Disorder Inventory and the Chinese Personality Assessment Inventory-2 assessing various disordered personality features. Adequate internal consistency was found for the borderline construct (α = .83). Exploratory factor analysis revealed two components: (1) affective and cognitive disturbances, and (2) impulse dysregulation, which were replicated by confirmatory factor analysis. Item analysis indicated that the various borderline criteria displayed similar levels of diagnostic efficiency, which does not support the elimination of fear of abandonment and transient psychotic features from the EUPD and IPD criteria set. Findings of this study suggest that BPD, EUPD, and IPD may represent analogous diagnostic categories across classification systems.
