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

Abstract

Abstract:The assessment of personality disorders assumes unquestioned clinical relevance when considering the prevalence rates in the general population. Tests assessing the typical pathological traits of these disorders has been adapted to and developed in Brazil. However, there is a gap in the country of screening tools for personality disorders. Screening tools are designed to allow a fast and informative application on the likelihood of a positive diagnosis, where the consequence should be conveyed to a diagnostic assessment. Using as a base the Dimensional Clinical Personality Inventory (IDCP), developed at the national level, the objective of this research was to develop a screening tool for personality disorders, as well as investigate its diagnostic accuracy. The study included 1,196 people, aging between 18 and 73 years (M = 26.32, SD = 8.69), and 64.1% female. The sample was divided into clinical and non-clinical group. We used an empirical approach based on criteria for selection of items similar to those adopted in the development of Minnesota Multiphasic Personality Inventory was used (MMPI). The logistic regression analysis and also the calculation of Cohen´s d indicated the items that best discriminate against people with personality disorders and those without this diagnosis. We achieved a final set of 15 items with satisfactory sensitivity and specificity for screening test. We discusses the strengths and limitations of screening version of the IDCP and guidelines for further study.

External validity study of a personality disorders screening test in a community sample

“…Compared of the amount of individuals identified by other screening tests for personality disorders, we found very similar data to what is reported in the literature for community samples, ranging from 43% to 54.4% 17,19,20 . This suggests that the IDCP screening version is comparable to screening for personality disorders used in the world, confirming the favorable data found previously 21 .…”

“…Based on previous research 21 and in the requirement for knowing the strengths and weaknesses of a measure using external criteria 24 , this research reports validity evidence based psychological tests and relevant sample characteristics. Data suggest that the screening version of IDCP (IDCP-SV) discriminates a similar percentage of people from the community to what is found in other countries with similar tools for screening of personality disorders.…”

“…Recently, a screening test for personality disorders developed in Brazil was proposed 21 . The Dimensional Clinical Personality Inventory (IDCP) screening version (SV) was builded using the full version IDCP items 22 as a starting point.…”

“…The study of Carvalho et al 21 described step by step the development process and diagnostic accuracy indicators of IDCP-SV. However, no relationship between screening measure and other scales or external criteria was tested.…”

“…Foi aplicado o Inventário Dimensional Clínico da Personalidade -versão triagem (IDCP-triagem). O IDCP-triagem (Carvalho, Pianowski, & Reis, 2017) foi desenvolvido a partir da versão completa do IDCP (Carvalho & Primi, 2015), cujas propriedades psicométricas demonstraram adequação na literatura prévia (Carvalho, Primi, & Stone, 2014;Carvalho & Primi, 2016). A versão presentemente utilizada do IDCP visa realizar triagem de pessoas com suspeita de transtornos da personalidade.…”
