The aim of the study was to test the reliability and validity of the Dizziness Handicap Inventory in the Greek language (DHI).
This study was performed in a university tertiary centre. Internal consistency was estimated using Cronbach's alpha for the DHI, physical (DHI-P), functional (DHI-F) and emotional (DHI-E) subscale scores. Correlation between DHI (total and subscales) and the SOT (sensory organisation test) as well as correlation between the DHI and FGA (functional gait assessment) was tested using Spearman's correlation coefficient. Test-retest reliability was tested using ICC (Intraclass Correlation Coefficient).
Ninety (90) patients were included in the study.
Internal consistency was excellent for the total score and very good for the physical functional and emotional subscale scores. No statistically significant correlation was found between SOT and DHI. There was a moderate correlation between FGA and total DHI scores (r = -0.472; p < 0.0001) and poor to moderate between FGA and DHI subscale scores (DHI-E r = -0.342; p = 0.001, DHI-F r = -0.448 p < 0.0001, DHI-P r = -0.472 p < 0.0001). Test-retest reliability was excellent.
Greek version of DHI is recommended as a valid measure for patients with vestibular disorders.
本研究旨在测试希腊语版头晕残障量表（DHI）的信度和效度。
本研究在一所大学三级医疗中心开展。使用克朗巴哈系数对DHI、身体（DHI-P）、功能（DHI-F）和情感（DHI-E）分量表得分进行内部一致性估计。使用斯皮尔曼相关系数检验DHI（总分及各分量表）与感觉组织测试（SOT）之间的相关性，以及DHI与功能性步态评估（FGA）之间的相关性。使用组内相关系数（ICC）检验重测信度。
90名患者纳入本研究。
总分的内部一致性极佳，身体、功能和情感分量表得分的内部一致性良好。未发现SOT与DHI之间存在统计学显著相关性。FGA与DHI总分之间存在中度相关性（r = -0.472；p < 0.0001），FGA与DHI各分量表得分之间存在低到中度相关性（DHI-E r = -0.342；p = 0.001，DHI-F r = -0.448，p < 0.0001，DHI-P r = -0.472，p < 0.0001）。重测信度极佳。
推荐希腊语版DHI作为前庭疾病患者的有效测量工具。
