Are Anancastia and Disinhibition two sides of the same coin? Psychometric studies of the pathological personality traits model of the ICD-11
Transtorno de Personalidade, Modelo Dimensional, Psicometria
The dimensional model of assessment and diagnosis of Personality Disorders proposed by the ICD-11
suggests five traits that describe personality pathology. These are: Negative Affectivity, Dissociality,
Detachment, Disinhibition, and Anankastia. As it is a relatively recent model, studies indicate the need for
its improvement through psychometric studies that provide evidence of its validity and consistency. Some
studies suggest, for example, that there may be a psychometric inconsistency between the dimensions of
Anankastia and Disinhibition. The present project is a cross-sectional observational study, aiming to
examine the dimensional structure of these pathological personality traits, with a special emphasis on the
Anankastia and Disinhibition dimensions. To this end, five instruments will be administered:
Sociodemographic Questionnaire, PiC D-Br, FFiCD-Br, PID-5-BF+M, and BFI-2-S. Adults aged 18 and
over, of any gender, will participate in this study. About 1,000 participants will be recruited from various
resources available in a virtual environment. The aim is to describe the dimensional structure of
pathological personality traits according to the ICD-11 model, with an emphasis on the psychometric
characteristics of the Anankastia and Disinhibition dimensions.
