The PersoniCAT Project

Supporting specialized psychiatric care in remote areas: A computer-adaptive interview for the assessment of personality pathology.

About the project

The goal of this project is to develop an adaptive instrument for assessing personality disorders. The instrument that we are developing is based on principles of computerized adaptive testing. This means that the instrument is governed by an algorithm and adapted real-time, so that only the questions that are relevant and contribute important information needed to make the diagnosis are selected. Using the adaptive algorithm will allow for delivering a relatively short, yet precise, personalized test; while ensuring adequate content coverage.

We aim to develop an instrument that will be more intuitive to use than the current generation of semi-structured interviews. Over the last 18 months, we developed and tested different algorithms that could guide the selection of questions during test administration, and compared their performance using simulated data. The best performing algorithm will be implemented in the final version of the adaptive test. In addition, we interviewed Norwegian clinicians about their experience with diagnostic instruments for personality disorders. The focus was on identifying the strengths and weaknesses of these instruments; allowing us to take these into account when developing our adaptive test - which we want to be as user-friendly as possible.
