The main purpose of this study was to evaluate the psychometric abilities of the Norwegian version of the voice-related quality of life (V-RQOL) measure. A subsidiary goal was to examine whether the formulation of two additional questions would contribute to strengthen the test.
A total of 104 patients with voice disorders received the V-RQOL measure, voice handicap index (VHI), and a visual analog scale (VAS). Seventy-eight patients returned the forms, of which 16 were excluded because they did not meet the inclusion criteria. Analyses were carried out on 62 patients. Forty-one healthy control subjects fulfilled the V-RQOL measure, of which 36 were used in the analysis.
The V-RQOL measure showed a strong internal consistency (Cronbach alpha=.84-.91) and a good test-retest reliability (r=0.86-0.90). Construct validity was demonstrated with strong correlations to VHI (r=0.91) and VAS (r=0.78), together with a significant difference between patients and controls V-RQOL score. The two additional questions in the broadened version (V-RQOL12) had high mean scores (3.86 and 3.10) and strong item-total correlations (0.61 and 0.75), showing that these are important questions, measuring the same construct as the rest of the test.
The Norwegian version of the V-RQOL measure is a valid and reliable tool that discriminates well between voice and nonvoice patients. A broadened version of the instrument seems to strengthen the test.
本研究的主要目的是评估挪威语嗓音相关生活质量（V-RQOL）量表的心理计量学能力。次要目标是研究增加两个问题的表述是否有助于增强该测试。
共 104 名嗓音障碍患者接受了 V-RQOL 量表、嗓音障碍指数（VHI）和视觉模拟量表（VAS）的评估。78 名患者返回了问卷，其中 16 名因不符合纳入标准而被排除。对 62 名患者进行了分析。41 名健康对照组完成了 V-RQOL 量表的评估，其中 36 名被用于分析。
V-RQOL 量表显示出较强的内部一致性（Cronbach α=0.84-0.91）和良好的重测信度（r=0.86-0.90）。与 VHI（r=0.91）和 VAS（r=0.78）的强相关性以及患者和对照组 V-RQOL 评分的显著差异表明该量表具有良好的结构效度。扩展版本中的两个附加问题（V-RQOL12）的平均分较高（3.86 和 3.10），与总分的相关性较强（0.61 和 0.75），表明这些问题很重要，与测试的其余部分测量相同的结构。
挪威语 V-RQOL 量表是一种有效且可靠的工具，能够很好地区分嗓音和非嗓音患者。该工具的扩展版本似乎增强了测试。
