Revisão da dimensão isolamento do inventário dimensional clínico da personalidade

Abstract

ResumoO presente estudo teve como objetivo revisar a dimensão Isolamento do Inventário Dimensional Clínico da Personalidade (IDCP). Para tanto, o método foi dividido em duas etapas, sendo a primeira voltada para elaboração de novos itens com base na literatura, e a segunda visou a verifi cação das propriedades psicométricas do novo conjunto de itens. O IDCP em conjunto ao Inventário de Personalidade NEO Revisado (NEO-PI-R) e o Personality Inventory for DSM-5 (PID-5) foram aplicados em uma amostra de 213 sujeitos, entre 18 e 69 anos (M = 25,56; DP = 8,70), e maioria do sexo feminino (74,3%). A primeira etapa resultou em uma versão de 39 itens, dos quais 28 eram novos. A segunda, resultou em uma dimensão composta por 18 itens, em quatro fatores interpretáveis de acordo com as análises de estrutura interna, sendo, Individualismo, Isolamento Social, Evitação de Intimidade e Apatia Emocional, com coefi cientes de consistência interna de 0,88 para o total, e superior a 0,75 para os fatores. A correlação da dimensão com o NEO-PI-R e o PID-5 revelou magnitudes coerentes e esperadas. Os dados demonstram a adequação da nova dimensão Isolamento do IDCP.

Review of the Isolation Dimension of the Dimensional Clinical Personality Inventory AbstractThe present study aimed to review the Isolation dimension of the Dimensional Clinical Personality Inventory (DCPI). The method was divided in two steps, the fi rst focused on developing new items based on the literature, and the second for testing the psychometric properties of the new items dataset. The DCPI plus the Revised NEO Personality Inventory (NEO-PI-R) and the Personality Inventory for DSM-5 (PID-5) were applied in a sample of 213 subjects aging between 18 and 69 years (M = 25.56; SD = 8.70), with predominance of women (74.3%) The fi rst step resulted in 39 items, of which 28 were new. The second stage results on a composite of 18 items, in four interpretable factors based on the internal structure analysis, Individualism, Social Isolation, Intimacy Avoidance and Emotional Apathy with internal consistency coeffi cients of .88 for total, and higher then .75 for each factor. The correlations of the scale with NEO-PI-R and PID-5 revealed consistent and expected effect sizes. The data reveal the adequacy of the new Isolation dimension of DCPI.

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).…”

Development and Diagnostic Accuracy of the Screening of the Dimensional Clinical Personality Inventory

“…Thus, we sought items that contributed to the prediction of people belonging to clinical groups, emphasizing the weight and significance of items in logistical regression analyses, and also which items showed greater difference in scores between the groups. It is noteworthy that partial analyzes were included (i.e., items from the original IDCP kept in the IDCP-2 and items that make up the Mood Instability dimension) in order to support these items in the final selection of the screening, given the quality of the items kept in the IDCP-2 (e.g., Carvalho, & Arruda, 2016;Carvalho, Pianowski, & Miguel, 2015;Carvalho, & Sette, 2015;2017;Carvalho, Sette, Capitão, & Primi, 2014;Carvalho, Souza, & Primi, 2014) and in the suitability of the content of Mood Instability in the identification of symptoms of PDs (e.g., Abela et al, 2015;Carvalho & Primi, 2016). The first group of analyses, using 147 items of the IDCP, pointed out a group of 31 items as more discriminative.…”

“…It is noteworthy that for the first regression analysis, with all the items, only the forward method (wald) was used, since many predictor variables were inserted. The analysis covering only the 61 items kept between the IDCP and its revised version, IDCP-2, was performed considering that (a) the items kept in the revised version are empirically those which presented higher psychometric adequacy in previous studies (e.g., Carvalho & Arruda, 2016;Carvalho, Pianowski, & Miguel, 2015;Carvalho, & Sette, 2015;, 2017;Carvalho, Sette, Capitão, & Primi, 2014;Carvalho, Souza, & Primi, 2014) and (b) despite some items shared with the analysis covering the IDCP in general, it is a different grouping of predictive variables. Similarly, in the third group of analyses, only the 27 items composing the Mood Instability dimension were used, since data presented in previous studies suggested this dimension as subjacent to pathological personality functioning in general (e.g., Abela, Carvalho, Cho, & Yazigi, 2015;Carvalho, & Primi, 2016;.…”

Investigation of the clinical functioning of the Dimensional Clinical Personality Inventory 2 criticism avoidance dimension

“…Psychometric properties of the dimensions, evidence of validity (based on the internal structure and external variables) and reliability indices (for internal consistency) have been shown to be appropriate in studies that provide a basis for the IDCP-2. 19,[23][24][25][26][27] For the present study, we used the revised version of the criticism avoidance dimension, 19 which contains 18…”
