Assessing borderline personality disorder based on the Hierarchical Taxonomy of Psychopathology (HiTOP): Dimensional Clinical Personality Inventory 2 – BPD

Abstract

A new approach to mental disorder taxonomy was recently proposed, the Hierarchical Taxonomy of Psychopathology (HiTOP). The aim of this study was to develop a specific version of the Dimensional Clinical Personality Inventory 2 (IDCP-2), a self-reported measure developed in Brazil for use in pathological personality traits assessment, focused on the assessment of traits related to BPD in accordance with the HiTOP model. In step 1 we developed new factors to cover all traits of BPD according to HiTOP. In step 2, data were collected from 207 adults from the community (N = 207; M age = 35.9). Participants completed the developed measure (IDCP Borderline Personality Disorder Scale; IDCP-BPD), and selected factors from IDCP-2, PID-5, FFBI and FFHI. Exploratory structural equation modeling (E-SEM) suggested a 3-factors solution for the grouping of the fifteen factors of the IDCP-BPD.Factors and total score reliability was good. Correlations between IDCP-BPD factors and external measures were coherent, corroborating our expectations. The bootstrap two-sample t-test comparing the healthy and pathological groups suggested good discrimination capacity of the IDCP-BPD factors, mainly the Fragility and Impotence feelings factors. Favorable evidence was found for the use of IDCP-BPD to BPD traits measurement. The new factors extend the coverage of IDCP-2 in measuring BPD symptoms. Correlations suggest that IDCP-BPD factors measure the traits considered as relevant according to HiTOP. Discriminant capacity of the factors also supports the use of the measure, although future studies must replicate this in samples composed of BPD patients. personality disorders, differential diagnosis, emotional instability, psychological assessment

Validation of the hyperbolic temperament questionnaire in Iran

“…As expected, the negative affectivity strongly and disinhibition, somewhat milder, were psychopathological domains related to the HTQ. Because these two domains are strongly linked with borderline features in the Hierarchical Taxonomy of Psychopathology (HiTOP) [ 33 , 34 ], borderline features can address some pathways between them and hyperbolic temperament. The correlation between neuroticism or emotional instability as a key component of BPD [ 5 , 8 , 9 ] and HTQ points to an indirect link between borderline features and hyperbolic temperament.…”
