This study examined the knowledge gained and behavioral changes made by vocal performers after attending a vocal hygiene education program. A single-group, pretest-posttest research design was utilized to examine the improvement of voice care knowledge and decrease of phonotraumatic behaviors in vocal performers. Data analysis involved a comparison of pretest and posttest responses from an online questionnaire. A paired sample t test revealed a statistically significant improvement in the participants' knowledge regarding the larynx, voice production, and vocal hygiene. In addition, a behavioral inventory revealed improved hydration habits, decreased caffeine and alcohol intake, and healthier responses to symptoms of throat irritation or vocal fatigue. The findings from this study will contribute to evidence regarding the benefits of having vocal performers attend a vocal hygiene education program in order to increase their knowledge about voice production and care, decrease at-risk vocal behaviors, and improve healthy vocal practices.
