Eccentricity dimension of the Dimensional Clinical Personality Inventory: Review and psychometric properties

Abstract

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.

Pathological personality and quality of life: Validity evidences for IDCP-2

“…This pattern, only observed in the models considering several traits at the same time (but not observed in one by one correlations), can occur as an effect related to the measurement of pathological traits, mainly Conscientiousness and Attention Seeking, as discussed previously in literature (Carvalho, Pianowski, Silveira, Bacciotti, & Vieira, 2016;Carvalho, Souza, & Primi, 2014). Indeed, these pathological traits tend to seem less impaired in comparison to other pathological traits.…”

Verification of the Internal Structure of the Dimensional Clinical Personality Inventory 2 in a Brazilian Community Sample

“…The idcp-2 is composed of 206 items distributed in 12 dimensions, with a 4-point Likert-type response scale (1 = "has nothing to do with me" and 4 = "has a lot to do with me"). Previous studies indicated the validity of idcp-2 factors (e.g., Carvalho, Pianowski & Miguel, 2015;Carvalho, Pianowski, Silveira, Bacciotti & Vieira, 2016;Carvalho, Sette & Ferrari, 2016).…”
