Abstract:
The Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive assessment suitable for diverse populations. However, the test-retest reliability and internal consistency of the Arabic version of RUDAS were not examined. This study aimed to examine these aspects. The Arabic RUDAS was administered twice to a sample of 37 older adults. The intraclass correlation coefficients and the Kappa coefficient examined the test-retest reliability. The internal consistency of the Arabic RUDAS was assessed using Cronbach’s alpha. The RUDAS showed high internal consistency (α = 0.866) and test-retest reliability (ICC = 0.971), with substantial agreement between tests (Kappa = 0.78). The Arabic RUDAS is highly reliable with Palestinian older adults.
