© 2017 S. Karger AG, Basel. Background: Impairment in personality functioning (PF) represents a salient criterion of the DSM-5 alternative diagnostic model for personality disorders (AMPD). The main goal of this study is to analyze the relationship of the borderline personality disorder (BPD) clinical components derived from the DSM-5 categorical diagnostic model (affective dysregulation, behavioral dysregulation, and disturbed relatedness) with personality organization (PO), i.e., PF, assessed by the Structured Interview of Personality Organization (STIPO). Methods: STIPO and the Structured Clinical Interviews for DSM-IV (SCID-I and-II) were administered to 206 BPD patients. The relationship between PO and BPD components were studied using Spearman correlations and independent linear regression analyses. Results: Significant positive correlations were observed between STIPO scores and several DSM-5 BPD criteria and comorbid psychiatric disorders. STIPO dimensions mainly correlated with disturbed relatedness and, to a lesser extent, affective dysregulation components. Each BPD clinical component was associated with specific STIPO dimensions. Conclusions: Both diagnostic models, DSM-5 BPD criteria and PO, are not only related but complementary concepts. The results of this study particularly recommend STIPO for the assessment of relational functioning, which is a major domain of the Personality Functioning Scale Levels of the DSM-5 AMPD.
