La Personalidad como Vulnerabilidad Unidimensional y Bidimensional: el Papel Mediador de las Variables Cognitivas en la Gravedad Sintomatológica en una Muestra de Personas con Trastorno Grave de Personalidad

Abstract

The problems of conceptualization of personality disorders (PD) and their adjustment within the rest of pathologies continue to boost a promising research and clinical effort that helps to identify transdiagnostic processes and suggest heuristic interaction models. Understanting personality from the framework of diathesis, we analized the mediating role of a number of variables in symptom severity in a sample of people with severe PD (N = 310). By means of cluster analysis, we found a two-dimension typology that divides exhaustively and exclusively 100% of the participants. Mediation analyses found that personality as a one-dimension continuum has an effect on symptomatic severity mediated by negative automatic thoughts and by cognitive fusion; its effect as a two-dimension typology (internalization and externalization) appears to be mediated only by automatic thoughts. These findings and their implications are discussed in the context of a new paradigm of a process-based clinical science.
