Abstract

Background: The aim is to validate Turkish version Rowland Universal Dementia Assessment Scale (RUDAS). Methods: One hundred forty patients (>65 years) were included. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition -V was used in all patients. Rowland Universal Dementia Assessment Scale was applied for 2 days. Results were compared with Mini-Mental State Examination; reliability, validity, and statistical values were determined. Results: Time validity was verified. Mini-mental state examination was correlated 45.3% in control and 73% in dementia group. Factor weights varied between 0.44 and 0.81; factor construct was verified as 6-item scoring. When 25 was cutoff point, sensitivity was 92.86% and specificity was 92.86%. Content validity index was found to be 100% by 7 specialists. Cronbach alpha (0.692) and test-retest reliability (intraclass correlation = 0.987) were determined. Conclusion: Rowland Universal Dementia Assessment Scale (Turkish) is validated and verified as reliable. Test could be applied for 5 minutes approximately; results are not affected by educational status, immigrant status, and language used; however, age and gender have significant effect on results.
