Abstract: Problem considered The main study objective was the translation and validation of the Moroccan dialect version dizziness handicap inventory questionnaire (DHI-M). Methods A prospective cross-sectional study was conducted between January 2021 and January 2022, in the Otolaryngology Department of Casablanca University hospital, among patients with positional vertigo. The DHI-M questionnaire was translated according to the Forward-Backward method. It was filled before liberation and one week after. Statistical validation consisted in calculating internal consistency with Cronbach alpha α, construct validity, convergent validity, and responsiveness. Results In total, 40 patients were included. Mean DHI-M score was 43 ± 20. Internal consistency was good for total score (α = 0.90) and individual subscales scores (0.78 emotional, 0.77 physical, 0.74 functional). The total and subscales of DHI-M were strongly correlated with the FES-I (rho= 0.776, 95% CI [0.58-0.89], p˂0.001). The responsiveness of the DHI-M after one week of maneuver was excellent, with an effect size in all patient's superior to 0.8. Conclusion The DHI-M demonstrated good psychometric properties for patients with dizziness and can be recommended as a measure of disability and quality of life in Moroccan patients with positional vertigo.
