Description Within industrial psychology, there is a growing demand for tools that offer the possibility to analyze maladaptive, subclinical personality traits. Practitioners can use e.g. questionnaires capturing Dark Triad, or Dark Tetrad. Nevertheless, some attempts to adapt questionnaires that originated from a relatively novel classification of personality disorder were recorded. Traits of Dark Tetrad represent only a small part of this classification. The goal of this contribution is to introduce preliminary results regarding psychometric characteristics of a short version of The Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD) questionnaire that captures the aforementioned wider maladaptive personality traits. However, the administration of such methods is often connected with high-stakes situations (e.g. job interviews) with significant outcomes for a person. In these situations, people tend to distort their answers on rating scales. This happens both intentionally in an effort to present themselves in the best possible light and also unintentionally through a number of response biases. The shortcomings of traditional inventories caused by both intentional and unintentional distortion of responses are being to a certain degree eliminated by adopting the forced-choice (FC) format that we used for the adaptation of CAT-PD. One of the most promising approaches to modeling responses from FC questionnaires is e.g. Thustonian Item Response Theory model (TIRT). Because we also measured reaction time that we intend to utilize for a more accurate diagnosis of personality traits, we used the so-called Thurstonian D-Diffusion IRT model (TDIRT), which represents the link between TIRT and diffusion models. This model was used to validate the CAT-PD questionnaire. The advantage of D-Diffusion models lies in more accurate estimates of latent traits as well as in modeling several parameters with unique psychological interpretations (e.g. a parameter capturing the amount of information needed to make a decision). In this presentation, we discuss not only the preliminary results of the psychometric properties of CAT-PD, but we also describe the steps necessary for the adaptation of the FC format and for the application of TDIRT.
