Abstract: Background: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. Objective:Our study aimed to translate, cross-culturally adapt, and validate the BADLS to the Arabic language for people with neurocognitive decline and dementia. Methods: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. Results: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). Conclusion:The Arabic BADLS is a valid scale that can used to assess the functional performance of people living with dementia.
