The present study sought to determine the validity, reliability, and responsiveness of the Brazilian Portuguese Voice Symptom Scale (VoiSS) and also identify characteristics of efficacy and cutoff values that discriminate dysphonic from vocally healthy individuals.
Cross-sectional, nonrandomized, prospective study with controls.
Thirty hundred subjects (160 with dysphonia and 140 without dysphonia) completed the Brazilian version of the VoiSS as well as a vocal self-assessment scale using a five-point rating system (excellent, very good, good, fair, and poor).
The Brazilian version of VoiSS, referred to as the Escala de Sintomas Vocais (ESV), was valid, reliable, and responsive. A score of 16 was determined to be highly sensitive (100%) and specific (100%) for individuals with dysphonia.
The Brazilian version of VoiSS or ESV demonstrated a high degree of validity, reliability, and responsiveness with regard to differentiating aberrant vocal function and was valuable as an instrument to quantify the response to treatment in patients with dysphonia. The cutoff value that discriminates individuals with dysphonia from vocally healthy subjects was 16.
本研究旨在确定巴西葡萄牙语语音症状量表（VoiSS）的有效性、可靠性和反应性，并确定区分嗓音障碍者和嗓音健康者的疗效特征及临界值。
采用对照的横断面、非随机前瞻性研究。
300名受试者（160名嗓音障碍者和140名无嗓音障碍者）完成了巴西版VoiSS以及采用五点评分系统（优秀、非常好、好、一般和差）的嗓音自我评估量表。
巴西版VoiSS，即嗓音症状量表（ESV），具有有效性、可靠性和反应性。对于嗓音障碍者，16分的得分具有高度敏感性（100%）和特异性（100%）。
巴西版VoiSS或ESV在区分异常嗓音功能方面具有高度的有效性、可靠性和反应性，并且作为量化嗓音障碍患者治疗反应的工具具有重要价值。区分嗓音障碍者和嗓音健康受试者的临界值为16分。
