Cross-Cultural Adaptation of Gujarati Version of Rowland Universal Dementia Assessment Scale for Assessing Cognition in Elderly Population

Abstract

Background: The Rowland Universal Dementia Assessment Scale (RUDAS) has less educational bias when compared to other cognitive assessment scales like MMSE and MoCA. But its performance has not been adequately addressed in Indian population. Moreover, there are very less scales for cognition which are available in Guajarati language which can be taken in elderly population. Therefore, the reliability and validity of Gujarati-RUDAS in elderly population needs to be tested. Purpose: To determine the reliability and validity of the translated Gujarati version of Rowland Universal Dementia Assessment Scale (RUDAS) for assessing cognition in elderly population. Methodology: A total of 60 subjects were included in this study according to the inclusion criteria. After gaining cross-cultural adaptations, reliability was assessed with intra-rater and inter-rater reliability, analyzed by intraclass correlation coefficient (ICC). Validity was assessed with content validity, analyzed by content validity index (CVI), Result: Intra-rater reliability was having good reliability with ICC value of 0.757 and inter-rater reliability was found to be moderately reliable with ICC value of 0.700. Content validity was found to be good with CVI of 1. Conclusion: The Gujarati version of RUDAS (G-RUDAS) is a reliable and valid tool for the screening of cognitive impairment among elderly population.
