Abstract
Objectives: The purpose of this study was to determine the validity and reliability of a Japanese version of the Khalfa hyperacusis questionnaire (KHQ) and proposed a threshold KHQ score for classifying hyperacusis.
Methods: In total, 112 patients with hyperacusis (group A) and 103 patients without hyperacusis (group B). The patients in group A were further classified into the following subgroups: subjects with hyperacusis as their chief complaint (n = 26, group A1) and subjects with hyperacusis accompanied by chief complaints of tinnitus and/or hearing loss (n = 86, group A2).
Results: The average total questionnaire score for patients in group A was 11.8 ± 9.7, which was statistically significantly higher than that of patients in group B, 5.7 ± 4.8. Cronbach’s coefficients for internal consistency were high for the total score (0.92). The average total scores for groups A1 and A2 were 18.1 ± 11.1 and 9.9 ± 8.4, respectively, and the difference between the groups was statistically significant.
Conclusions: We developed a Japanese version of the KHQ. It showed high reliability and validity; suggesting its usefulness in clinical practice. We propose that a total KHQ score of 16 is an appropriate cutoff for classifying hyperacusis

目的: 本研究的目的是确定日本版Khalfa 听觉过灵问卷 (KHQ) 的有效性和可靠性, 并提出用于听觉过灵分类的阈值KHQ评分。
方法: 共有112例听觉过灵 (A组) , 103例无听觉过灵 (B组) 。 A组患者进一步分为以下亚组: 听觉过灵为主要病症 (n = 26, A1组) ;听觉过灵伴有耳鸣和/或听力丧失的主要病症 (76例, A2组) ) 。
结果: A组患者平均总问卷得分为11.8 ± 9.7, B组为5.7 ± 4.8, A组比B组高, 其差异具有统计学意义。内部一致性的克朗巴赫系数对于总分 (0.92) 来说是高的。 A1组和A2组平均总分分别为18.1 ± 11.1和9.9 ± 8.4, 其差异在统计学上是显著的。
结论: 我们开发了日本版的KHQ, 它显示出高的可靠性和有效性, 表明其在临床实践中的有用性。我们建议, 总KHQ评分16是听觉过灵分类的适当截止值。
