Translation and validation of the Arabic version of the amyotrophic lateral sclerosis assessment questionnaire (ALSAQ40-AR)

ALSAQ40-AR and the WHOQOL-BREF were reliable and valid tools to evaluate QOL in patients with ALS; we suggest that the validated ALSAQ40-AR is more suited for ALS patients because it is a disease specific questionnaire that showed higher internal consistency with no floor or ceiling effects. QOL in ALS was correlated with time since disease onset, disease stage, functional, and cognitive disabilities.
