Establishing the reliability and the validity of the Arabic translated versions of the Effort Assessment Scale and the Fatigue Assessment Scale.

Objective: The aim was to establish the reliability and the validity of Arabic translated versions of the Fatigue Assessment Scale (FAS) and the Effort Assessment Scale (EAS).

Design: The FAS and the EAS were translated from the original English following a recommended six-step approach for translating hearing-related questionnaires for different languages. The reliability of the scales was investigated using Cronbach's alpha, item-total correlation, and inter-item correlation.
