Conventional vestibulometric techniques are inadequate for quantifying the impact of dizziness on everyday life. The 25-item Dizziness Handicap Inventory (DHI) was developed to evaluate the self-perceived handicapping effects imposed by vestibular system disease. The development of the preliminary (37 items) and final versions (25 items) of the DHI are described. The items were subgrouped into three content domains representing functional, emotional, and physical aspects of dizziness and unsteadiness. Cronbach's alpha coefficient was employed to measure reliability based on consistency of the preliminary version. The final version of the DHI was administered to 106 consecutive patients and demonstrated good internal consistency reliability. With the exception of the physical subscale, the mean values for DHI scale scores increased significantly with increases in the frequency of dizziness episodes. Test-retest reliability was high.
传统的前庭测量技术不足以量化头晕对日常生活的影响。25项头晕残障量表（DHI）旨在评估前庭系统疾病所带来的自我感知的残障效应。本文描述了DHI初步版本（37项）和最终版本（25项）的编制过程。这些项目被分为三个内容领域，分别代表头晕和不稳的功能、情感和身体方面。基于初步版本的一致性，采用克朗巴哈系数来衡量信度。DHI最终版本应用于106例连续患者，显示出良好的内部一致性信度。除身体亚量表外，DHI量表得分的平均值随头晕发作频率的增加而显著升高。重测信度较高。
