Datos primarios asociados al artículo enviado a Personality Disorders: Theory, Research, and Treatment, Person-centered approaches in the field of personality allow greater understanding of how different subpopulations with specific personality profiles are linked with related clinically relevant predictors or outcomes. Studies under the Five Factor Model offer consensus on the observation of a Resilient, an Undercontrolled and an Overcontrolled profile. However, studies using maladaptive traits are much more limited. The present research aimed to identify personality profiles based on the 25 maladaptative facet and examined the relationships between the profiles and personality dysfunctioning, internalizing and externalizing symptoms. A mixed sample composed of community adults (n = 742) and patients (n = 312) completed the Personality Inventory for DSM-5 Short Form, the Inventory of Depression and Anxiety Symptoms-II, Externalizing Spectrum Inventory–Brief From, the 12 items Spanish version of the WHO Disability Assessment Schedule II and Level of Personality Functioning Scale-Brief Form 2.0. Latent profile analysis was performed to identify profiles based scores on the 25 maladaptive personality trait facets scales of the PID-5-SF. The scores on internalizing, externalizing and functioning were compared across the profiles obtained, by analyzing the equality of means. Four personality profiles that differed in both level and shape emerged: Resilient, Undercontrolled, Overcontrolled, and Ordinary type. The Overcontrolled and Undercontrolled types showed higher scores on pathology scales than the Resilient and Ordinary types. While the Overcontrolled profile appeared more related to internalizing symptoms and impairment in self-functioning, the Undercontrolled profile was more linked to higher scores on externalizing symptoms and interpersonal dysfunctioning., This work was supported by the grant “Reliable and clinical relevant change of Inventory of Depression and Anxiety Symptoms II – IDAS-II: a longitudinal clinical utility study (RELY-IDAS-II)”, project PID2020-116187RB-I00 on Proyectos I+D+i 2020 “Retos del Conocimiento” provided by Ministerio de Ciencia e Innovación (Spain).

Datos primarios asociados al artículo enviado a Journal of Personality Assessment, Since the publication of the Alternative Model on Personality Disders in Section III DSM-5, literature has widely focused on providing validity evidence for the 25 facets defined in Criterion B. More recently, scientific attention has shifted towards Criterion A, with a considerable set of mixed results both supporting and disagreeing the operational definition of the model. The present study aims to provide additional evidence on the structural and relational differentiation of self and interpersonal dimensions of personality functioning using a quick screener, the Level of Personality Functioning Scale – Brief Form 2.0 (LPFS-BF 2.0), in a community and clinical mixed sample. 1074 participants (717 community adults and 357 patients) completed the LPFS-BF 2.0, the Personality Inventory for DSM-5 Short Form and the Questionnaire for the World Health Organization Disability Assessment. The internal structure of LPFS 2.0 was assessed through a series of Confirmatory Factor Analyses and bifactor modeling was applied to assess the dimensionality. Exploratory Structural Equation Modelling was used to explore the joint structure of functioning and maladaptive traits. Multiple linear regressions, controlling for age and sex, were employed to evaluate the predictive validity of LPFS scales in explaining functional impairment. Our results clearly support a two-factor structure of criterion A (self and interpersonal functioning) when measured with LPFS-BF 2.0. Results also displayed clear differences between the personality functioning factors, with the self-functioning factor more closely linked to facets of the negative affect domains and the interpersonal-functioning factor linked to several antagonistic personality traits. Moreover, our results suggested a relevant role of self-functioning in the explanation of the functional impairment along and beyond personality facets. These results lead to consider the LPFS-BF 2.0 a useful tool for clinical routine monitoring self and interpersonal personality functioning., This work was supported by the grant “Network-Psyco: Modelización a través de redes empíricas de las conexiones entre facetas y rasgos psicológicos”, project UHU-1257470 on Programa Operativo FEDER Andalucía 2014-2020, provided by Fondo Europeo de Desarrollo Regional (EU) and by Ministry of Universities of the Government of Spain (PRX21/00319).
