A patient's self-assessment of his/hers vocal problem and the analysis of the results of a treatment are means used to verify the effectiveness of an intervention and to develop directive procedures for clinical health practice. Psychometric instruments are the most common tools used to perform this task. Validation of self-assessment instruments may be carried out in several ways; however there should be clear and structured criteria involved in this process.
To present the validation process of three voice self-assessment instruments for the Brazilian Portuguese language: Voice-Related Quality of Life--V-RQOL, Voice Handicap Index--VHI and, Voice Activity and Participation Profile--VAPP. These instruments received respectively the following names: Qualidade de Vida em Voz - QVV, Indice de Desvantagem Vocal--IDV and Perfil de Participação e Atividades Vocais--PPAV, emphasizing their specificities and the necessary adaptations for their use in Brazil.
The three questionnaires were validated following the guidelines suggested by the Scientific Advisory Committee of Medical Outcomes Trust--SAC.
The psychometric measures of validity, reliability, reproducibility and sensitiveness were statistically demonstrated for each instrument.
The Brazilian versions of the V-RQOL, VHI and VAPP demonstrated to be valid, reliable and sensitive instruments that specifically assess patients who present voice problems. These instruments can be used in the assessment of the life quality related to voice, as well as for the analysis of treatment outcomes.
患者对自身嗓音问题的自我评估以及对治疗结果的分析，是用于验证干预措施有效性和制定临床健康实践指导程序的手段。心理测量工具是执行此任务最常用的工具。自我评估工具的验证可以通过多种方式进行；然而，这一过程应涉及明确且结构化的标准。
介绍三种巴西葡萄牙语嗓音自我评估工具的验证过程：嗓音相关生活质量量表（V-RQOL）、嗓音障碍指数（VHI）和嗓音活动与参与度概况量表（VAPP）。这些工具分别采用了以下名称：嗓音生活质量量表（QVV）、嗓音障碍指数（IDV）和嗓音活动与参与度概况量表（PPAV），强调了它们的特性以及在巴西使用时所需的调整。
按照医学结局信托科学咨询委员会（SAC）建议的指南对这三份问卷进行验证。
统计显示了每种工具在效度、信度、可重复性和敏感性方面的心理测量指标。
巴西版的V-RQOL、VHI和VAPP被证明是有效、可靠且敏感的工具，可专门用于评估存在嗓音问题的患者。这些工具可用于评估与嗓音相关的生活质量，以及分析治疗结果。
