The purpose of this study was to adapt and determine reliability, validity, and responsiveness of voice-related quality of life (V-RQOL) for Persian. A total of 300 patients with voice disorders participated in the study. Also, 116 people without any voice disorders volunteered to participate in the study as a control group. All participants filled in the Persian version of V-RQOL. The reliability, validity, and responsiveness were studied. Results demonstrated that the discrimination coefficient is significant for all items. The V-RQOL measure showed a strong internal consistency (Cronbach alpha coefficient = 0.88-0.91) and a good test-retest reliability (r = 0.93-0.95). Pre- and post-treatment results showed a significant responsiveness (functioning, 0.000; social-emotional, 0.001; and total, 0.000). Effect size range of 1.26-1.59 and the standardized response mean range of 1.07-1.41 were obtained for V-RQOL. It seems that the Persian version of V-RQOL is valid, reliable, and responsive to change, and this questionnaire can be used for completing voice evaluation for patients with dysphonia.
本研究的目的是改编并确定波斯语版嗓音相关生活质量（V-RQOL）量表的信度、效度和反应度。共有300名嗓音障碍患者参与了该研究。此外，116名无嗓音障碍者自愿作为对照组参与研究。所有参与者均填写了波斯语版V-RQOL量表。对其信度、效度和反应度进行了研究。结果表明，所有项目的区分系数均具有显著性。V-RQOL量表显示出较强的内部一致性（克朗巴赫α系数=0.88 - 0.91）和良好的重测信度（r = 0.93 - 0.95）。治疗前后结果显示出显著的反应度（功能维度，0.000；社会情感维度，0.001；总分，0.000）。V-RQOL量表的效应量范围为1.26 - 1.59，标准化反应均数范围为1.07 - 1.41。波斯语版V-RQOL量表似乎有效、可靠且对变化有反应，该问卷可用于完成嗓音障碍患者的嗓音评估。
