RAMOS, Juan M.; BROCO, Laura; SANCHEZ, Aintzane  and  DOLL, Aurora. Personality as unidimensional and bidimensional vulnerability: the mediator role of cognitive variables in symptom severity in a sample of people with severe personality disorder. Clínica y Salud [online]. 2020, vol.31, n.1, pp.1-12.  Epub Feb 17, 2020. ISSN 2174-0550.  https://dx.doi.org/10.5093/clysa2019a18.

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 suggestheuristic 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.

Keywords : Personality disorder; Automatic thoughts; Dimensionality; Mediation analysis.
