Quality of life related with the voice of teachers: exploratory systematic review of literature

The objective of this study was to verify, through a systematic revision of literature, the existents studies on quality of life concerning to the voice of professors. It was accepted articles of the Education Resources Information Center ( ERIC ,) LILACS, PUBMED Central (PMC) and SCIELO in Portuguese, English or Spanish, using the uniterms “quality of life’ and ‘voice’, without determination about the period of publication. The articles had been enclosed in accordance with standardized formularies. The initial search resulted in 315 articles. For articles selection were previously established inclusion and exclusion criteria applied and the Relevance Tests I and II. Articles were included according to standardized forms. The initial search resulted in 315 articles. The analysis process involved reading of headings, abstracts and complete texts; and only 13 articles had filled the inclusion criterion, involving studies of quality of life concerning to the voice of professors of the diverse levels of education (infantile, basic, average and superior) of public and private schools. The quality of life in voice was the most widely used instrument with teachers, and the physical domain of instrument was the one which impacted in a negative way in the quality of life concerning to the voice, considering speaking loud in noisy environments and the air finishes fast and needs to breathe many times while speaks. It had certain difficulty at the moment of the analyses of the articles, since that it had not presented similar standardization of techniques and criterion. There is the necessity of increasing the studies of quality of life concerning to the voice of the professor in the different levels of education and types of schools.

本研究旨在通过系统文献综述，验证现有关于教师嗓音相关生活质量的研究成果。本次检索纳入葡萄牙语、英语及西班牙语文献，来源涵盖教育资源信息中心（Education Resources Information Center，ERIC）、LILACS、PubMed中心（PubMed Central，PMC）及SciELO，检索单元词为“生活质量”与“嗓音”，未限定发表时间范围。所有文献均按照标准化表单完成收录。初始检索共获取315篇文献。文献筛选环节基于预先设定的纳入与排除标准，结合相关性测试I与相关性测试II开展，所有纳入文献均遵循标准化表单完成流程。初始检索共获取315篇文献。分析过程涵盖标题、摘要及全文阅读环节，最终仅13篇文献符合纳入标准，这些研究涉及公立与私立学校不同教育阶段（学前、初等、中等及高等教育）教师的嗓音相关生活质量。嗓音相关生活质量量表是教师群体中应用最为广泛的评估工具，而该量表的生理维度对教师嗓音相关生活质量产生了负面影响，具体表现为在嘈杂环境中需提高音量说话、气息耗竭过快且说话过程中需频繁换气。本次分析过程存在一定难度，原因在于现有研究的技术与评价标准未实现统一标准化。未来亟需针对不同教育阶段与办学类型的教师，进一步开展嗓音相关生活质量领域的研究。
