Development and internal structure investigation of the Dimensional Clinical Personality Inventory

Abstract

This study aimed to develop a dimensional instrument to assess personality disorders based on Millon's theoretical perspective and on DSM-IV-TR diagnoses criteria, and seek validity evidence based on internal structure and reliability indexes of the factors. In order to do that, a self-report test composed of 215 items, the Dimensional Clinical Personality Inventory (DCPI) was developed and applied to 561 respondents aged between 18 and 90 years (M = 28,8; SD = 11.4), with 51.8% females. Exploratory factor analysis and verifi cation of reliability were performed using Cronbach's alpha. Data provided validity evidence based on internal structure of the instrument according to the theory of Millon and DSM-IV-TR.

“…It consists of 163 items distributed in 12 dimensions: dependency, aggressiveness, mood instability, eccentricity, attention seeking, distrust, grandiosity, isolation, criticism avoidance, self-sacrifice, conscientiousness, and impulsiveness. We verified the psychometric properties of the instrument in several studies (Carvalho & Primi, 2015, in which we found favorable evidence of validity and adequate reliability indexes.…”

“…On the other hand, we calculated the IDCP factors scores based on the T-scale, i.e., mean 50 and standard deviation of 10, using as a reference the non-patients sample of Carvalho and Primi (2015).…”

“…The greater the preference for violent games, the greater is the frequency of aggressive thoughts, corroborating previous data (Chory & Goodboy, 2011;Hasan et al, 2013), besides a higher mistrust of other people's intentions, impulsivity, and emotion attribution of anger towards other people. Additionally, the most impulsive people were those who reported a preference for action games and violence, which makes sense considering the relationship of the Impulsivity dimension with sadistic and antisocial functioning (Carvalho & Primi, 2015. People who prefer live RPG had higher scores in Grandiosity that is individuals who tend to want to stand out among others, to be admired, according to the traits assessed by the dimension (Carvalho & Primi, 2015).…”

“…In this study, we employed the general emotional perception score, the general distortion score, and the scores of each of the eight emotions, i.e., frequency of each emotion. Psychometric studies with PEP demonstrated adequate accuracy and validity, and there is a relation between the ability to perceive emotions and other measures of intelligence and emotional perception, whereas there is a relation between distortions and individual frequency of emotions and personality characteristics (Miguel & Pessotto, 2016;Miguel & Primi, 2014 Dimensional Clinical Personality Inventory (IDCP): It is a self-report instrument for the evaluation of pathological personality traits designed by Carvalho and Primi (2015). It consists of 163 items distributed in 12 dimensions: dependency, aggressiveness, mood instability, eccentricity, attention seeking, distrust, grandiosity, isolation, criticism avoidance, self-sacrifice, conscientiousness, and impulsiveness.…”

“…The intelligence test assessed abstract reasoning ability (understanding relationships between concepts without previous learning) and verbal reasoning (understanding relationships between words) (Primi & Almeida, 2000). We evaluated these personality traits: dependency (feelings of inferiority and the need for others to make decisions), aggressiveness (interest in violence and aggressive behaviors), mood instability (sudden mood swings), eccentricity (perception of self as being different), (suspicion of others' intentions), grandiosity (sense of superiority and view of oneself as better than others), isolation (avoidance of social experience), avoidance of criticism (embarrassment with social situations), self-sacrifice (making oneself more available to others than to himself), conscientiousness (worry with detail and perfection), and impulsiveness (adventurous and reckless behavior) (Carvalho & Primi, 2015).…”
