What do amateur singers who perform in religious services know about vocal health and hygiene?

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Purpose

To describe the knowledge of amateur singers who perform in religious services, about vocal health and hygiene, and compare these findings at two different moments.

Methods

Descriptive, longitudinal research with 100 participants who practice amateur singing in religious services; ages between 18 and 82 years (average 33.72 years), 54 women and 46 men. Participants answered the Initial Questionnaire (Q1), which includes personal data and vocal self-assessment, and the Vocal Health and Hygiene Questionnaire (QSHV), on two occasions with an interval of 20 days and with the questions randomized. The participants were given a feed-back of the QSHV after each application i.e. the correct answers to each item. The data were analyzed descriptively and inferentially.

Results

Most singers reported some degree of self-assessed vocal alteration and reported at least one vocal symptom (mainly throat clearing and voice failure). The score was higher in the second application of the QSHV and there was no correlation between the vocal self-assessment and the score obtained in the QSHV.

Conclusion

Amateur singers of both sexes who perform in religious services demonstrated knowledge about vocal health and hygiene corresponding to that of vocally healthy individuals, above the cutoff point in both applications; however, the majority reported vocal changes and symptoms. There was an increase in knowledge about vocal health and hygiene in the second application, however discreet. The level of knowledge about vocal health and hygiene did not correlate with the degree of vocal alteration.
