CARVALHO, Lucas de Francisco. Review Study of the Impulsiveness Dimension of the Dimensional Clinical Personality Inventory. Univ. Psychol. [online]. 2018, vol.17, n.1, pp.58-68. ISSN 1657-9267.  https://doi.org/10.11144/javeriana.upsy17-1.rsid.

The present study aimed to review the Impulsiveness dimension from Dimensional Clinical Personality Inventory (IDCP) as well as to verify its psychometric properties in a non-clinical sample. The procedures were performed in 2-stages. Step 1 was directed at the development of new items and Step 2 intended for testing the psychometric properties of the revised version. As a result of the first step, we selected a set of 38 items. In the second step, the items were tested in a sample of 225 subjects (70.1% females), aged 18 to 66 years (M = 26.2, SD = 8.1), mostly undergraduate students (58.9%). All subjects answered the IDCP, and the Brazilian versions of both, the Revised NEO Personality Inventory (NEO-PI-R) and the Personality Inventory for DSM-5 (PID-5). As result, we obtained a set of 18 items in three interpretable factors, Inconsequence, Risk Taking, and Deceitfulness, with internal consistency coefficients (Cronbach’s α) of .89 for the total score. The correlations of the Impulsiveness factors with NEO-PI-R and PID-5 revealed consistent and expected relations. The data reveal the adequacy of the revised dimension of IDCP.
