The goal of the present study was to characterize a large population of Brazilian individuals using the Brazilian Portuguese version of the Voice-Related Quality of Life (V-RQOL) Measure.
We studied a population of 2,214 Brazilian subjects who completed the V-RQOL questionnaire consisting of 10 questions from two domains: physical functioning and social-emotional functioning. The subjects were divided into two groups according to the presence of vocal complaints: group 1, with vocal complaints (1,304 individuals); group 2, without vocal complaints (910 individuals). Subject age ranged from 14 to 90 years in both groups. All subjects self-rated their voice quality upon a five-point categorical scale ranging from poor to excellent. Moreover, the respondents' professions were classified into four categories according to their level of voice usage.
Results indicate that the worse the self-assessment of the voice, the lower the V-RQOL scores, with higher significance in the group with vocal complaints. The total V-RQOL score was 97 for excellent voices, 92 for very good, 84 for good, 65 for fair, and 45 for poor voices. Main correlations for both groups were: total and physical scores (0.96), total and social-emotional scores (0.82); physical and social-emotional scores (0.69); self-assessment of the voice and total score (0.61); self-assessment of the voice and physical score (0.58), and self-assessment of the voice and social-emotional score (0.52). Two interesting negative correlations were found between age and self-assessment of the voice (-0.271), and age and social-emotional score (-0.184). Group 1, with vocal complaints, presented lower scores than group 2.
The relationship between self-assessment of voice quality and V-RQOL scores was very clear and statistically significant, especially when considering the group with a known voice disorder.
本研究的目的是使用巴西葡萄牙语版的嗓音相关生活质量（V-RQOL）量表对大量巴西个体进行特征描述。
我们研究了2214名巴西受试者，他们完成了V-RQOL问卷，该问卷由来自两个领域的10个问题组成：身体功能和社会情感功能。根据是否有声带问题，受试者被分为两组：第1组，有声带问题（1304人）；第2组，无声带问题（910人）。两组受试者的年龄范围均为14至90岁。所有受试者根据从差到优的五点分类量表对自己的嗓音质量进行自我评分。此外，根据嗓音使用水平，将受访者的职业分为四类。
结果表明，嗓音自我评估越差，V-RQOL得分越低，在有声带问题的组中具有更高的显著性。嗓音质量为优时，V-RQOL总分是97分，嗓音质量为很好时是92分，嗓音质量为好时是84分，嗓音质量为中等时是65分，嗓音质量为差时是45分。两组的主要相关性为：总分与身体功能得分（0.96）、总分与社会情感得分（0.82）；身体功能得分与社会情感得分（0.69）；嗓音自我评估与总分（0.61）、嗓音自我评估与身体功能得分（0.58）、嗓音自我评估与社会情感得分（0.52）。在年龄与嗓音自我评估（-0.271）以及年龄与社会情感得分（-0.184）之间发现了两个有趣的负相关。第1组，即有声带问题的组，得分低于第2组。
嗓音质量自我评估与V-RQOL得分之间的关系非常明确且具有统计学意义，尤其是在考虑已知嗓音障碍的组时。
