“…Items must be answered from a Likert scale of four points, ranging from “it has nothing to do with me” (1) and “it has a lot to do with me” (4). Psychometric properties of dimensions, validity evidence (based on the internal structure and external variables) and reliability indices (for internal consistency) have shown to be appropriate in studies that provide a basis for the IDCP‐2 (e.g., Carvalho et al ., , ). We also used the original dimension (Carvalho & Primi, ), consisting 13 items, as a mean to perform the equating procedure, as related in the next topic.…”

“…Dimensions are Dependency, Aggressiveness, Mood Instability, Eccentricity, Attention Seeking, Distrust, Grandiosity, Isolation, Avoidance of Criticism, Self‐sacrifice, Conscientiousness, and Inconsequence. A number of studies verifying the psychometric qualities of the instrument is published (e.g., Carvalho & Sette, ; Carvalho & Silva, ; Carvalho & Pianowski, ; Carvalho, Souza & Primi, ), and new efforts have been undertaken to find clinical cutoff for each revised dimension (e.g., Carvalho, Pianowski & Hauck Filho, ; Carvalho, Sette & Capitão, ). The present study aims to establish a clinical cutoff for the Distrust dimension, using item‐level evaluation procedures, and hence, more evidence of the psychometric properties of the instrument.…”

The Clinical Dimensional Personality Inventory 2 (IDCP-2) is a 206-item self-report tool developed for the assessment of 12 dimensions (divided into 47 factors) of personality pathology. One of the scales comprising the instrument, the Distrust scale, is intended to provide psychometric information on traits closely related to the Paranoid Personality Disorder (PPD). In the present research, we used the Item Response Theory and the Receiver Operating Characteristic curve analysis to establish a clinical meaningful cutoff for the Distrust scale. Participants were 1,679 adults, among outpatients diagnosed with PPD, outpatients diagnosed with other PDs, and adults from the community. The Wright map revealed that outpatients were located at the very high levels on the latent continuum of the Distrust scale, with a very large effect size for the mean difference between patients and non-patients. The ROC curve supported a cutoff at -1.00 score in theta standardization which yielded 0.87 of sensitivity and 0.54 of specificity. Findings from the present investigation suggest the IDCP-2 Distrust scale is useful as a screening tool of the core features of the PPD. We address potential clinical applications for the instrument and discuss limitations from the present study.

“…Several personality dimensions could be acknowledged as pertinent to BPD; however, conceptually and as in line with previous studies, 13,14 we highlight the dimensions of dependency, mood instability, and inconsequence, since they include factors related to separation insecurity, oscillation and emotional vulnerability, as well as impulsiveness and extreme reactions. [16][17][18][19] The aim of this study was to investigate the most discriminant IDCP-2 dimensions and factors to distinguish people diagnosed with BPD from people without this diagnosis. To that end, we administered three dimensions of the IDCP-2, namely dependency, mood instability, and inconsequence, also considering their individual factors.…”

“…Validity evidence (based on internal structure and external criteria) and reliability indexes were assessed for these dimensions in previous studies, indicating the psychometric adequacy of these dimensions and their respective factors [16][17][18][19][20][21]. Previous studies[16][17][18][19][20][21] found validity evidence for the IDCP-2, including coherent correlations between its dimensions and factors with the Personality Inventory for DSM-5 (PID-5). For our sample, Cronbach's alphas calculated for the dimensions varied from 0.87 to 0.91.…”

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.

“…For this study, we embrace five dimensions in eight factors of interest: Dependency (Avoidance of Abandonment and Insecurity), Aggressiveness (Violence), Mood Instability (Anxious concern and Vulnerability), Distrust (Angry distrust), and Self-sacrifice (Hopelessness and Self-devaluation and Submission). Previous studies presented the validity and reliability of these factors [26,27,[35][36][37][38][39][40]. The administered version of the IDCP-BPD was composed of 116 items.…”

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
