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.

晕眩障碍量表摩洛哥版的跨文化改编

主要研究目的是对摩洛哥方言版头晕障碍量表（DHI-M）进行翻译和验证。方法于2021年1月至2022年1月在卡萨布兰卡大学医院耳鼻喉科对体位性眩晕患者进行前瞻性横断面研究。DHI-M问卷采用前向-后向法翻译。解放前和解放后一个星期都是满的。统计验证包括计算内部一致性与Cronbach α，结构效度，收敛效度和反应性。结果共纳入40例患者。平均DHI-M评分为43±20分。总分（α = 0.90）和个体分量表得分（情绪0.78，身体0.77，功能0.74）的内部一致性较好。DHI-M总分和分量表与FES-I有很强的相关性（rho = 0.776, 95% CI [0.58-0.89]， p小于0.001）。1周后DHI-M的反应性非常好，所有患者的效应量均大于0.8。结论DHI-M对眩晕患者具有良好的心理测量特性，可作为衡量摩洛哥体位性眩晕患者残疾程度和生活质量的指标。
