The purpose of this prospective study was to perform the Brazilian Voice-Related Quality of Life (V-RQOL) version and to check its psychometric measurement properties and the relationship between vocal self-assessment and the instrument's scores. The translation and validation were performed following the guidelines of the Scientific Advisory Committee of Medical Outcomes Trust. The instrument was administered to 234 patients, 114 with vocal complaints, and 120 without vocal complaints. The instrument was submitted to validation, reliability, reproducibility, and responsiveness evaluation. Results showed that internal consistency was demonstrated with high coefficient values (P<0.001) and a statistically acceptable level of reliability (functioning 0.700; social-emotional 0.070; and total 0.108). Pre- and posttreatment results showed a significant responsiveness (Functioning 0.026; Social-Emotional 0.006; and Total 0.008). The study concluded that the Brazilian version of the V-RQOL is valid, reliable, and responsive to change and it can play an important role in the dysphonic patient's voice evaluation.
这项前瞻性研究的目的是实施巴西版嗓音相关生活质量（V-RQOL）量表，并检验其心理测量特性，以及嗓音自我评估与该量表得分之间的关系。翻译和验证工作按照医疗结局信托科学咨询委员会的指导方针进行。该量表应用于234例患者，其中114例有嗓音问题，120例无嗓音问题。对该量表进行了效度、信度、可重复性和反应度评估。结果显示，内部一致性通过高系数值得到证明（P<0.001），且信度在统计学上处于可接受水平（功能维度0.700；社会情感维度0.070；总分维度0.108）。治疗前后结果显示出显著的反应度（功能维度0.026；社会情感维度0.006；总分维度0.008）。该研究得出结论，巴西版V-RQOL量表有效、可靠且对变化有反应，它可以在嗓音障碍患者的嗓音评估中发挥重要作用。
