Background And Objective: The voice handicap index-10 (VHI-10) questionnaire is widely used and is self-administered by the patient. It saves time for both patient and clinician as it is a 10-item questionnaire compared to the 30-item questionnaire in the original version of VHI. The purposes of the present study were to generate an Arabic version of the VHI-10, and to evaluate its validity, consistency, and reliability in normal and voice-disordered Arabic population. Setting And Design: This is a prospective study that has been carried out at Communication and Swallowing Disorders Unit, King Saud University. Subjects And Methods: The validated Arabic VHI-10 was administered to 100 patients with variable voice disorders and 165 control subjects. Internal consistency and test re-test reliability were evaluated. The results of the pathological and the control groups were compared. Results: The Arabic VHI-10 showed high internal consistency (Cronbach’s α = 0.88). Excellent test–retest reliability was found for the total scores of the Arabic VHI-10 (r = 0.920, P = 0.001). There was a significant difference between VHI-10 scores of the control and the voice disordered group (P < 0.001). Conclusion: This study demonstrated that Arabic VHI-10 is a valid tool for self-assessment of voice disorders that can be used by Arabic language speakers.
