To investigate the occurrence of self-reported vocal complaints in the professional use of the voice in professional theater actors; analyze the correlation between the presence of vocal complaint and three self-assessment protocols of the vocal problem impact; The Voice Symptom Scale (VoiSS), the Vocal Tract Discomfort (VTD) scale and the Voice Handicap Index -10 (VHI -10); verify the most robust protocols to identify dysphonia in this population.
Methods
The participants were 75 professional theater actors, men and women, between 18 and 64 years old. They answered to a questioner informing presence or absence of vocal complaint and to three self-assessment protocols: VoiSS, VTD and VHI-10.
Results
25% of the actors presented vocal complaints. The group with vocal complaint (GwVC) had more voice symptoms and higher frequency and intensity of vocal tract discomfort than the group with no vocal complaint (GnVC). No group presented voice handicap considering the VHI-10 and a very high correlation between the VTD frequency and intensity scores. The GnVC presented moderate correlation between the VoiSS and the VTD, moderate correlation between the VoiSS and the VHI-10 and, a very high correlation between the VTD frequency and intensity scores.
Conclusion
In this study, 25% of professional theater actors presented vocal complaints. The correlation between vocal complaints and protocols was positive and ranged from moderate to strong. The VoiSS and the VTD were more robust identify dysphonia in the GwVC.
