Informatics and Cognitive Assessment: A RUDAS Scale Paradigm

Abstract

Background: Cognitive assessment is an essential element of the screening process of Alzheimer’s disease. The prevalence of dementia is increasing and so are the numbers of immigrants and elderly population relocating and in need for health diagnosis and treatment. However, most of the psychometric tools used in psychological assessments are time-consuming and suffer from biases of language and cultural restrictions. Objectives: Our objective was to create a computerized version of a multicultural cognitive screening test, which would simplify cognitive assessment of elderly multicultural population, as routine part of health check-up procedures. Methods: The application was implemented in Android Studio and was written in Java code with the use of a home PC and a tablet. Rowland Universal Dementia Assessment Scale (RUDAS) was chosen. RUDAS is a cognitive screening tool with good psychological characteristics, which was created for multicultural and bilingual populations and was free to download. The collaboration with an authorized psychologist was essential for the ethics of the psychometric science. Results: The complete computerized version of RUDAS will include the six-item questionnaire, assessing specific cognitive domains which are in high correlation with Alzheimer’s screening process, such as registration, visuospatial orientation, praxis, visuo-constructional drawing, judgment, memory recall and language. Conclusion: The utilization of informatics in making cognitive assessment a user-friendly, validated, not time- or cost-consuming procedure would add value to psychometric tools which still are administered with “pen and paper”, when this proceeds with respect to the ethics of the science.
