Abstract
There are few Arabic language functional scales for patients with dementia. The Bristol Activity of Daily Living Scale (BADLS) was designed and validated for use in patients with dementia.
Our study aimed to translate, cross-culturally adapt, and validate the BADLS to the Arabic language for people with neurocognitive decline and dementia.
The original BADLS scale was translated to the Arabic language followed by face validity assessment through a pilot testing in five Arabic countries. The Arabic BADLS was assessed in a sample of 139 participants and their caregivers for concurrent and convergent validity.
The Arabic BADLS had excellent internal consistency, Cronbach's alpha 0.95 (95% CI 0.93-0.96). Likewise, the Arabic BADLS had strong convergent validity with the Montreal Cognitive Assessment (r = -0.82, p < 0.001).
The Arabic BADLS is a valid scale that can used to assess the functional performance of people living with dementia.
