Revision of the grandiosity dimension of the Dimensional Clinical Personality Inventory and verification of its psychometric properties

Abstract

Introduction: Personality disorders are among the most common disorders seen in clinical psychology. However, in Brazil there are few instruments for assessing the pathological characteristics of personality. Results: A total of 285 new items were developed and content analysis was used to select 33 of these to comprise the final version destined for administration. The results of parallel analysis and factor analysis identified four interpretable factors. Internal consistency coefficients were deemed acceptable and varied from 0.73 to 0.84 for the factors. Additionally, the expected correlations between the IDCP Inventory and the other tests were observed. Conclusion: This study demonstrates the revised dimension's suitability for assessment of the pathological traits of narcissistic personality disorder.

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

“…For the development of new items for the Eccentricity dimension, we verified the literature considered relevant in the pathological personality field, intended to understand the pathological manifestations of the underlying construct of the dimension, replicating previously procedures (Carvalho & Arruda, 2016;Carvalho & Sette, 2015;Carvalho & Sette, in press;Carvalho, Sette, & Ferrari, 2016;Carvalho, Sette, Capitão et al, 2014;Carvalho & Silva, 2016;Carvalho, Souza et al, 2014a, 2014b. We consult the Section 3 of the DSM-5 (APA, 2013a), the facets of the Personality Inventory for DSM-5 (PID-5) (Krueger, Derringer, Markon, Watson, & Skodol, 2012), the dimensions of the Shedler-Westen Assessment Procedure (SWAP-200) (Shedler & Westen, 2004) and the model of Clark (1990) that supports the Schedule for Nonadaptive Personality (SNAP).…”

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

“…The impulsivity trait of personality is recognized to bring substantial decrease in the quality of life, especially as part of a personality disorder, as borderline or antisocial (Carvalho, Sette, & Ferrari, 2016;Millon & Grossman, 2007a, 2007b). The other two factors, Risk Taking and Deceitfulness, did not imply a decrease in the quality of life or life satisfaction, which leads to the conclusive that a high score in Inconsequence is not related to high scores in these two 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).…”
