From categorical diagnosis to dimensional assessment of borderline personality

Abstract

Recent research suggested that personality disorders could be diagnosed as a continuous phenomenon. Therefore, in our study we examined whether the dimensional model of pathological personality traits could be applied to the assessment of borderline personality 1. For this purpose, we modified an existing measure of borderline personality, the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), and scrutinized its psychometric properties (i.e., reliability, factorial structure, criterion validity). To assess criterion validity we calculated correlations with pathological personality traits. Our sample comprised 354 participants (67.8% women). Confirmatory factor analysis revealed that the modified MSI-BPD measures borderline personality as a global construct, giving one-factor structure. The reliability of the measurement was excellent (α = .90). Moreover, we found positive associations between borderline personality and all five pathological personality traits, which supports the validity of the continuous assessment of borderline personality. Our findings suggest that the DSM-5 dimensional model may be applied in the assessment of borderline personality.

Przegląd kryteriów diagnostycznych, cech i typów osobowości borderline wraz z próbą ich porządkowania

“…: współwystępowanie diagnostyczne, niespójne rozróżnienia diagnostyczne oraz heterogeniczność. Od momentu pojawienia się ujęcia dymensjonalnego badacze potwierdzają empiryczną wiarygodność i użyteczność modelu patologicznych cech osobowości w ocenie BPD (Campbell, Clarke, Massey, Lakeman, 2020;Gamache i in., 2021;Henriques-Calado i in., 2021;Huczewska, Didyk, Rogoza, 2019). Dla przykładu, Henriques-Calado i in.…”

The alternative model of personality disorders or early maladaptive schemas? Usefulness for understanding borderline features in a non-clinical adult sample

“…Researchers point to cognitive and perceptual dysregulation as a feature that should be included in the proposed set, among others, as a representation of the ninth traditional diagnostic criterion (Bach and Sellbom, 2016;Bach et al, 2016a). These studies also highlight that other characteristics (or entire domains) are essential for BPD (Bach and Sellbom, 2016;Bach et al, 2015;Huczewska et al, 2019). The coexistence of other disorders is an additional problem.…”
