ABSTRACT
PURPOSE: To analyse the relationship between the risk of dysphonia and vocal quality in undergraduate performing arts students. METHODS: Observational cross-sectional study with 38 undergraduate students in Performing Arts. We applied screening protocols for general and specific risk of dysphonia for actors and made recordings of sustained emission of the vowel /a/, spontaneous speech and reading a text, used for perceptual analysis performed by three evaluators using the GRBASI scale. After intra and inter-rater reliability tests it was obtained final classification of the general degree of vocal deviation parameter for each participant. Comparisons were made considering groups that had or did not have other profession/activity with the use of voice, and the groups were formed from the general grade. RESULTS: Most students were at high risk for dysphonia. All had vocal alteration, with a predominance of mild degree. Students who had another profession/activity with voice use scored higher in the specific protocol for actors, and in the sum of this protocol with the general screening protocol. There was no relationship between the degree of vocal alteration and the risk of dysphonia. Students who did not yet work professionally had more moderate or severe vocal alterations, and those who did work professionally had a higher frequency of mild vocal alterations. CONCLUSION: Most students were at high risk for dysphonia. All had vocal alteration, with a predominance of mild alteration. There was no relationship between the risk of dysphonia and the degree of vocal alteration.
OBJETIVO: Analisar a relação entre o risco de disfonia e a qualidade vocal em estudantes de graduação em Artes Cênicas. MÉTODO: Estudo transversal observacional com 38 estudantes de graduação em Artes Cênicas. Foram aplicados protocolos de rastreio de risco de disfonia geral e específico para atores, e realizadas gravações da emissão sustentada da vogal /a/, fala espontânea e leitura de texto, usadas para análise perceptivo-auditiva, efetuada por três avaliadores, com o uso da escala GRBASI. Após testes de confiabilidade intra e interavaliadores chegou-se à classificação final do grau geral do desvio vocal para cada participante. Foram feitas comparações entre grupos que tinham ou não outra profissão/atividade com o uso da voz e os grupos formados a partir do grau geral. RESULTADOS: A maioria dos estudantes apresentou alto risco para disfonia. Todos apresentaram alteração vocal, com predominância de grau leve. Os estudantes que tinham outra profissão/atividade com uso da voz obtiveram maior pontuação no protocolo específico para atores, bem como na soma desse protocolo com o de rastreio geral. Não houve relação entre o grau de alteração vocal e o risco de disfonia. Os estudantes que ainda não atuavam profissionalmente apresentaram mais alterações vocais de grau moderado ou severo, e os que atuavam profissionalmente apresentaram com maior frequência alteração vocal de grau leve. CONCLUSÃO: A maior parte dos estudantes apresentou alto risco para disfonia. Todos apresentaram alteração vocal, com predomínio de grau leve. Não houve relação entre o risco de disfonia e o grau de alteração vocal.

OBJECTIVE: To propose a Dysphonia Risk Screening Protocol for Actors (DRSP-A), test its usability in conjunction with the General Dysphonia Risk Screening Protocol (G-DRSP), determine the cut-off point for a high risk of dysphonia in actors, and compare the risk of dysphonia between actors with and without voice disorders. METHOD: Observational cross-sectional study with 77 professional actors or students. The questionnaires were applied individually and the total scores were summed to calculate the final score of the Dysphonia Risk Screening (DRS-Final). The validity of the questionnaire was verified from the area under the Receiver Operating Characteristic (ROC) curve, and cut-offs were obtained based on diagnostic criteria for screening procedures. Voice recordings were collected for auditory-perceptual analysis and subsequent division into groups with and without vocal alteration. RESULTS: The sample showed a high risk of dysphonia. Higher scores in the G-DRSP and in the DRS-Final were found in the group that presented vocal alteration. The cut-off points established for the DRSP-A and DRS-Final were 0.623 and 0.789, respectively, with higher degrees of sensitivity than specificity. Thus, above these values, the risk of dysphonia is greater. CONCLUSION: A cut-off value was calculated for the DRSP-A. This instrument was proven to be viable and applicable. The group with vocal alteration had a higher score in the G-DRSP and DRS-Final, but there was no difference in the DRSP-A.
