Abstract

Abstract Introduction Borderline personality disorder (BPD) is one of the most widely studied personality disorders (PDs). It recurrently shows traits of emotional lability, anxiety, separation insecurity, depressiveness, impulsiveness, risk exposure, and hostility, mainly affecting the domains of negative affectivity and antagonism. Objectives To investigate the most discriminant dimensions of the Dimensional Clinical Personality Inventory (Inventário Dimensional Clínico da Personalidade 2 [IDCP-2]) to distinguish people diagnosed with BPD from people without this diagnosis. Methods A total of 305 participants were included in this study: psychiatric outpatients diagnosed with BPD (n = 30), psychiatric outpatients diagnosed with other PDs (n = 75), and a community sample (n = 200). BPD traits were assessed using the dependency, mood instability, and inconsequence dimensions of the IDCP-2. Results Analysis of variance (ANOVA) comparisons indicated highest mean measures in the BPD group, and mood instability factors were the most discriminant ones when considering all groups. Applying the multiple regression analysis, we found an adjusted r 2 = 0.50, and hopelessness was the most predictive measure (β = 0.32; t = 6.19; p < 0.001). Conclusions We found discriminatory capacity for factors of all dimensions, although at different levels, and more consistent results to discriminate the BPD group from the community sample.

Resumo

Resumo Introdução O transtorno da personalidade borderline (TPB) tem sido um dos transtornos de personalidade (TPs) mais estudados. O TPB recorrentemente apresenta traços de instabilidade emocional, ansiedade, insegurança de separação, depressividade, impulsividade, exposição ao risco e hostilidade, afetando principalmente os domínios relacionados à afetividade negativa e ao antagonismo. Objetivos Investigar as dimensões mais discriminativas do Inventário Dimensional Clínico da Personalidade 2 (IDCP-2) para distinguir pessoas diagnosticadas com TPB de pessoas sem esse diagnóstico. Métodos Foram incluídos no estudo 305 participantes: pacientes psiquiátricos com TPB (n = 30), pacientes psiquiátricos com outros TPs (n = 75) e amostra da população geral (n = 200). Os traços de TPB foram avaliados utilizando as dimensões dependência, instabilidade de humor e inconsequência do IDCP-2. Resultados As comparações com análise de variância (ANOVA) indicaram que o grupo TPB apresentou as maiores médias, e os fatores da dimensão instabilidade de humor foram os mais discriminativos ao se comparar os três grupos. Usando a análise de regressão múltipla, foi encontrado um r 2 ajustado = 0,50, e o fator desesperança foi o mais preditivo (β = 0,32; t = 6,19; p < 0,001). Conclusões Foi encontrada capacidade discriminativa para fatores de todas as dimensões, embora em diferentes níveis, e resultados mais consistentes quanto à discriminação foram observados para a distinção entre o grupo com TPB e a população geral.
