Application of the Unfolding Model to the Aggression Dimension of the Dimensional Clinical Personality Inventory (IDCP). Rev. colomb. psicol. [online]. 2014, vol.23, n.2, pp.339-349. ISSN 0121-5469.

This article compares the suitability of the dominance and unfolding models for the analysis of the Aggressiveness dimension in the IDCP (Dimensional Clinical Personality Inventory). The study included 975 subjects, with ages ranging from 18 to 81 years (M=29.82, SD=12.28), 58.9% of which were women. The IDCP is composed of 163 items and 12 dimensions; 27 items are related to Aggression. The analysis with the unfolding model indicated the exclusion of 15 items due to standard error. Results showed a better fit for the dominance model. This result may be due to the nature of the construct, because the items assess pathological aspects of personality representing one end of the continuum.

Palavras-chave : dominance model; unidimensional unfolding model; personality; personality disorders; item-response theory.
