“…These data also suggest the appropriateness of the reviewed dimension in the assessment of pathological levels of the construct. Still, these features encompassed by IDCP Eccentricity dimension are being considered relevant (Abela et al, 2015;Carvalho & Primi, 2015) to schizotypal and schizoid personality disorder (APA, 2013;Hopwood et al, 2012;Samuel et al, 2012).…”

“…The psychometrics analyses demonstrated adequate reliability coefficient for this dimension (α = .92) and for each dimension of IDCP, as well as validity evidence based on internal structure, by exploratory and confirmatory factor analysis, and rating scale model from IRT's Rasch model (Carvalho & Primi, 2015;Carvalho, Primi, & Stone, 2014); and based on external variables, as psychiatric diagnosis and psychological tests (Abela et al, 2015;Carvalho, Oliveira-Filho, Pessotto, & Bortoli, 2014;Carvalho & Primi, 2015.…”

“…The items cover the 12 dimensions of the IDCP, Dependency, Aggressiveness, Mood Instability, Eccentricity, Attention Seeking, Distrust, Grandiosity, Isolation, Criticism Avoidance, Self-sacrifice, Conscientiousness and Impulsiveness. Studies have shown the adequacy of the psychometric properties of the IDCP dimensions (Abela et al, 2015;Carvalho, Oliveira-Filho et al, 2014;Carvalho & Primi, 2015Carvalho, Primi, & Stone, 2014), including validity evidence based on internal structure (Classical Test Theory and Item Response Theory) and on the relation to external variables (NEO-PI-R and psychiatric diagnosis), and reliability coefficients for internal consistency.…”

“…The Eccentricity dimension revealed correlation with the schizotypal, schizoid (Abela et al, 2015;Carvalho & Primi, 2015) and paranoid personality disorders (Carvalho & Primi, 2016). The schizotypal disorder corresponds to a functioning with social deficits marked by discomfort in interpersonal relationships, cognitive and perceptual distortions and behavioural eccentricities; the schizoid is associated to a pervasive pattern of detachment in social relations and restrictions on emotional expression in interpersonal relationships; and the paranoid functioning exposes a durable pattern of distrust in interpersonal relationships, pervaded by suspicion of intent to others and emotional liability (APA, 2013).…”

We aimed to review of the Eccentricity dimension of the Dimensional Clinical Personality Inventory (IDCP), through two steps.The first one focused on developing new items and the second on testing the psychometric properties in a sample of 225 subjects (70.1% females), aging between 18 and 66 years, mostly undergraduate students (58.9%). The subjects answered the IDCP, and the Brazilian versions of the NEO-PI-R, PID-5 and MIS. The first step resulted in 42 items, which 22 were new. The ResumenDimensión Excentricidad del Inventario Dimensional Clínico de la Personalidad: Revisión y psicométricas propiedades. El estudio tuvo como objetivo revisar la dimensión Excentricidad del Inventario Dimensional Clínico de la Personalidad (IDCP), en dos pasos.Uno para el desarrollo de nuevos ítems y otro para probar las propiedades psicométricas en una muestra de 225 sujetos (70,1% mujeres), con edades entre 18 y 66 años, estudiantes universitarios en su mayoría (58,9%). Los sujetos respondieron el IDCP, y las versiones brasileñas del NEO-PI-R, PID-5 y MIS. El primer paso resultó en 42 ítems, los cuales 22 eran nuevos. El segundo, dio lugar a una mezcla compuesta de 18 ítems, agrupados en seis factores interpretables, Desapego interpersonal, Estilo excéntrico, Paranormalidad, Estilo persecutorio, Despersonalización y Inexpresividad emocional, con coeficientes de consistencia interna de 0,85 para el total, y entre 0,60 y 0,82 para los factores. Las correlaciones entre los instrumentos revelaron relaciones consistentes y esperadas. Los datos demuestran la idoneidad de la nueva dimensión Excentricidad del IDCP.Palabras clave: rasgos de personalidad; tests psicológicos; trastornos de la personalidad.

“…The analysis covering only the 61 items kept between the IDCP and its revised version, IDCP-2, was performed considering that (a) the items kept in the revised version are empirically those which presented higher psychometric adequacy in previous studies (e.g., Carvalho & Arruda, 2016;Carvalho, Pianowski, & Miguel, 2015;Carvalho, & Sette, 2015;, 2017;Carvalho, Sette, Capitão, & Primi, 2014;Carvalho, Souza, & Primi, 2014) and (b) despite some items shared with the analysis covering the IDCP in general, it is a different grouping of predictive variables. Similarly, in the third group of analyses, only the 27 items composing the Mood Instability dimension were used, since data presented in previous studies suggested this dimension as subjacent to pathological personality functioning in general (e.g., Abela, Carvalho, Cho, & Yazigi, 2015;Carvalho, & Primi, 2016;. Finally, for the fourth group analysis (i.e., Cohen's d) the percentile 75 (d=0.60) was arbitrarily established as a cutoff for selecting the most discriminative items.…”

Abstract:The assessment of personality disorders assumes unquestioned clinical relevance when considering the prevalence rates in the general population. Tests assessing the typical pathological traits of these disorders has been adapted to and developed in Brazil. However, there is a gap in the country of screening tools for personality disorders. Screening tools are designed to allow a fast and informative application on the likelihood of a positive diagnosis, where the consequence should be conveyed to a diagnostic assessment. Using as a base the Dimensional Clinical Personality Inventory (IDCP), developed at the national level, the objective of this research was to develop a screening tool for personality disorders, as well as investigate its diagnostic accuracy. The study included 1,196 people, aging between 18 and 73 years (M = 26.32, SD = 8.69), and 64.1% female. The sample was divided into clinical and non-clinical group. We used an empirical approach based on criteria for selection of items similar to those adopted in the development of Minnesota Multiphasic Personality Inventory was used (MMPI). The logistic regression analysis and also the calculation of Cohen´s d indicated the items that best discriminate against people with personality disorders and those without this diagnosis. We achieved a final set of 15 items with satisfactory sensitivity and specificity for screening test. We discusses the strengths and limitations of screening version of the IDCP and guidelines for further study.

A Brazilian Investigation of the 36- and 16-Item Difficulties in Emotion Regulation Scales

et al. 2016

Objective: About 10 years ago, Gratz and Roemer (2004) introduced the Difficulties in EmotionRegulation Scale (DERS), a 36-item self-report instrument measuring 6 areas of emotion regulation problems. Recently, Bjureberg et al. (2015) have introduced a new, briefer version of the DERS comprising only 16 of the 36 items included in the original version. Because no studies have yet crossvalidated the recently introduced 16-item DERS and the 36-item DERS has never been tested in Brazil, we sought to inspect the psychometric properties of scores from both DERS versions with a nonclinical Brazilian sample. Method: Participants were 725 adult volunteers aged 18-70 years (mean = 30.54, standard deviation = 10.59), 82.3% of whom were women. All were administered the DERS along with a number of other self-report and performance-based instruments. Data analyses inspected internal consistency, factor structure, and convergent as well as divergent validity of scores from both DERS versions. Results: Results show that scores from both DERS versions possess good psychometric properties. Interestingly, both versions correlated, in the expected direction, with psychopathology and showed no significant correlations with cognitive measures. Like in other studies, however, the Awareness factor of the 36-item DERS did not produce optimal validity and reliability indexes. Conclusion: Taken together, our findings indicate that the 16-item DERS may be preferred over the 36-item version and provide additional support to the differentiation between emotion regulation and cognitive tasks of emotional perception and abstract and verbal reasoning.
