Summary
A group Voice Program effectively reduced vocal symptoms and fatigue in teachers with voice disorders. Participants reported positive changes in vocal care habits following the intervention.
Area of Science:
- Speech and Hearing Sciences
- Occupational Health
- Educational Psychology
Background:
- Teachers are at high risk for voice disorders due to occupational demands.
- Vocal symptoms can significantly impact a teacher's professional life and well-being.
- Group interventions offer a scalable approach to address voice disorders in professional populations.
Purpose of the Study:
- To evaluate the efficacy of a group-based Voice Program for teachers with voice disorders.
- To analyze the impact of the program on objective vocal symptom measures.
- To assess self-reported changes in vocal habits and perceived vocal health.
Main Methods:
- Longitudinal study with pre- and post-intervention assessments in 23 female teachers.
- Utilized otorhinolaryngological and speech-language evaluations, including GRBAS scale, pitch, loudness, and VHI-10.
- Employed the Screening Index for Voice Disorder (SIVD) and Vocal Fatigue Index (VFI) for quantitative analysis.
Main Results:
- Statistically significant reduction in SIVD scores and reported vocal symptoms (throat clearing, cough, swallowing pain).
- Demonstrated a decrease in the overall average of Vocal Fatigue Index domains.
- Teachers reported positive self-perceived changes in vocal care and habits post-program.
Conclusions:
- The group Voice Program is effective in mitigating vocal symptoms, particularly those associated with vocal fatigue.
- The intervention promotes positive behavioral changes in vocal self-care among teachers.
- Group voice therapy is a viable strategy for managing occupational voice disorders in educators.
