Reliability and Validity of Rowland Universal Dementia Assessment Scale in Turkish Population.

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 α (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.
