目的/假设：其目的是开发一个简短的语音障碍评估工具，并将其与语音障碍指数（VIII）进行比较。研究设计：无嗓音障碍者和嗓音障碍者VHI的项目分析及缩写VHI的建立和验证。方法：对VHI项目进行临床共识审查，以优先考虑VIII项（共30项）中每个项目的临床价值。VHI的项目分析进行了使用100例语音问题和159名对照组的VIII响应。使用项目分析和临床共识结果选择10个最稳健的VIII项目，以形成语音障碍指数-10（VHI-10）。统计分析比较VHI-10与VHI的有效性进行了819例患者代表了广泛的语音障碍。结果如下：研究组的VHI和VHI-10评分的统计分析显示VHI和VHI-10之间没有统计学显著差异。无论诊断如何，VHI和VHI-10之间的相关性大于0.90（P= 0.01）。对各种嗓音障碍类别的VHI-10与VIII评分的比率进行了分析，发现其始终大于预期值（33%）。这表明VHI-10可能是比VHI更可靠的仪器。结论：VHI-10是VIII的一个强有力的代表，患者需要更少的时间来完成，而不会失去有效性。因此，VHI-10可以取代VHI作为量化患者对其语音障碍的感知的工具。
Objectives/Hypothesis: The objective was to develop an abbreviated voice handicap assessment instrument and compare it with the Voice Handicap Index (VIII). Study Design: Item analysis of the VHI in individuals without voice disorders and patients with voice disorders and creation and validation of the abbreviated VHI. Methods: Clinical consensus review of the VHI items was held to prioritize the clinical value of each of the VIII items (30 items in all). Item analysis of the VHI was performed using the VIII responses of 100 patients with voice problems and 159 control subjects. The 10 most robust VIII items were selected using the item analysis and clinical consensus results to form the Voice Handicap Index-10 (VHI-10). Statistical analysis comparing the validity of the VHI-10 with the VHI was performed with 819 patients representing a wide spectrum of voice disorders. Results: Statistical analysis of the VHI and VHI-10 scores from the study group showed no statistically significant differences between the VHI and the VHI-10. Irrespective of diagnosis, the correlation between the VHI and the VHI-10 was greater than .90 (P=.01). The ratios of the VHI-10 to VIII scores for a variety of voice disorder categories were analyzed and found to be consistently greater than the expected value (33%). This suggests that the VHI-10 may be a more robust instrument than the VHI. Conclusion: The VHI-10 is a powerful representation of the VIII that takes less time for the patient to complete without loss of validity. Thus, the VHI-10 can replace the VHI as an instrument to quantify patients' perception of their voice handicap.
