Voice Problems Among School Teachers employing the Tele-teaching Modality

Objectives

To assess the prevalence of voice problems among teachers in Riyadh during tele-teaching and examine the relationship between the Voice Handicap Index 10 (VHI10) scores and a variety of risk factors believed to be related to voice problems. We also assessed awareness of voice hygiene and therapy among teachers.

Study Design

An observational cross-sectional study conducted using a multistage random sampling method among Riyadh school teachers who taught by tele-teaching for a minimum of one year.

Methods

A self-assessment questionnaire which included demographic information about teachers, factors related to their teaching backgrounds, tele-teaching settings, effects of tele-teaching on the voice, medical and social histories, reports of voice and reflux symptoms, VHI10, and general knowledge about voice hygiene. This was distributed to school teachers using an SMS link through the Ministry of Education's IT department.

Results

A total 495 were included in the study after exclusions. The prevalence of teachers who had significant voice problems during tele-teaching (VHI10>11) was 21.6%. Multiple risk factors significantly increased the risk of voice problems during tele-teaching. These factors included being female, teacher age, the presence of background noise from both teachers and students, loud voices, using an open camera during the teaching, stress and anxiety, allergies, respiratory disease, reflux, hearing problems, and a family history of voice problems. Only 4.6% of respondents were familiar with voice hygiene and voice therapy, but 65% believe that it is important for teachers to be knowledgeable about them.

Conclusions

Due to the lower prevalence of voice disorders among tele-teaching compared to traditional teaching methods, tele-teaching may be a viable option for teachers who have voice problems. There are still several factors influencing voice problems among tele-teachers. To attenuate potential risks, it is crucial that teachers are aware of the concepts of voice hygiene and voice therapy.
