Effectiveness of a Blended-Learning Intervention in Teachers' Vocal Health.

OBJECTIVE: To verify the effectiveness of a blended-learning voice assistance program for elementary school teachers. STUDY DESIGN: Nonrandomized and comparative interventional clinical trial. METHODS: A total of 59 teachers participated; 33 of the 59 teachers participated in face-to-face learning (control group-CG), and 26 of the 59 teachers participated in blended learning (experimental group-EG). The Voice Assistance Program included the following for both groups: preintervention assessment, four voice workshops and postintervention assessment. The instruments used were the Vocal Production Condition - Teacher (VPC-T) questionnaire, the Screening Index for Voice Disorder (SIVD), the Vocal Health and Hygiene Questionnaire (VHHQ) and the Voice-Related Quality of Life (V-RQOL) measure. Additionally, voice samples were collected for auditory-perceptual analysis of voice quality. The workshops included theoretical and practical content for both groups. All the workshops for the CG were conducted face-to-face, while the workshops for the EG consisted of two online workshops and two face-to-face workshops. A descriptive analysis of the data was performed, and paired Wilcoxon and Mann-Whitney tests were performed using R software, with a significance level of 0.05. RESULTS: Both groups showed improved acquisition of knowledge regarding vocal health and improved voice quality, but the improvement was greater for the EG. There was a significant decrease in the risk of voice disorder in the EG. Only the CG showed significant improvement in voice-related quality of life. CONCLUSION: The voice assistance program with blended learning is effective for increasing knowledge about vocal health, reducing the risk of voice disorder and improving the voice quality of teachers.

Reporter's communicative performance, while wearing face masks, during the COVID-19 pandemic / Performance comunicativa dos repórteres com o uso de máscara facial durante a pandemia da COVID-19

ABSTRACT Purpose: to identify the impact of wearing protective face masks on reporters' communicative performance during the COVID-19 pandemic and verify whether there was an association between these aspects. Methods: a quantitative, descriptive, cross-sectional study with a sample of 32 reporters (16 females and 16 males) who worked, during the pandemic. Most participants had a bachelor's degree (n = 28; 87.5%). The sample's mean age was 35.09 years (SD = 9.41), and they had been working in the area for a mean of 10.09 years (SD = 7.62). Reporters answered an online form with 26 questions, developed by the researchers, on their self-perception of voice and communicative performance when wearing a mask, during the pandemic. Data were descriptively analyzed, and the chi-square test was applied with the Statistical Package for the Social Sciences 20 (SPSS). Results: most reporters (n = 20; 62.5%) classified their voices and speech articulation as good (n = 19; 59.4%) and reported difficulties hearing and/or being heard by interviewees in noisy places and perceived their voices were lower, muffled, or with a low volume (n = 28; 87.5%). Also, 22 (68.8%) reported having to speak louder than usually to be heard. Lastly, the questions on reporters' communicative performance were associated with wearing masks while reporting. Conclusion: wearing protective face masks, during reportage, negatively impacted reporters and was associated with their communicative performance.

RESUMO Objetivo: identificar o impacto do uso de máscara de proteção facial na performance comunicativa dos repórteres durante a pandemia da COVID-19, bem como verificar se existe associação entre esses aspectos. Métodos: trata-se de um estudo transversal, de caráter descritivo, com abordagem quantitativa. Participaram 32 repórteres que atuaram durante a pandemia, sendo 16 do sexo feminino e 16 do sexo masculino. A maioria dos participantes tinha ensino superior (n = 28; 87,5%). A amostra apresentou média de idade de 35,09 anos (DP = 9,41) e tempo de atuação na área de 10,09 anos (DP = 7,62). Os repórteres responderam a um formulário online composto por 26 questões, elaborado pelos próprios pesquisadores, sobre a autopercepção vocal e performance comunicativa do repórter com o uso de máscara durante a pandemia. Foi realizada análise descritiva dos dados e aplicado o teste Qui-quadrado por meio do software Statistical Package for Social Sciences 20 (SPSS). Resultados: a maioria dos repórteres (n = 20; 62,5%) classificou sua voz e articulação de fala como boas (n = 19; 59,4%). A maioria dos participantes relatou sentir dificuldade de ouvir e/ou ser ouvido pelo entrevistado em locais com ruído e perceber a sua voz mais baixa, com pouco volume ou abafada (n= 28; 87,5%), bem como 22 (68,8%) relataram ter que falar mais alto do que o normal para ser ouvido. Por fim, verificou-se a presença de associações entre as questões sobre a performance comunicativa dos repórteres e o uso de máscaras durante as reportagens. Conclusão: os repórteres apresentaram impactos negativos com uso das máscaras de proteção facial durante as reportagens, bem como verificou-se associação entre o uso destas com a performance comunicativa.
