Voice disorders in teachers have a significant impact on communication, quality of life, and economic costs to the healthcare system. We need to advance the prevention of voice disorders in teachers by testing an online telepractice model with synchronous (in real-time) and asynchronous (stored and accessed later) methods. The current study will investigate the effectiveness of the theoretically-driven Global Voice Prevention Model (GVPM) delivered by two methods; 1) online telepractice (synchronous and asynchronous) and 2) traditional, in-person for vocally healthy physical education and vocal music student teachers. Effectiveness of the model will be assessed by voice-related measures captured daily on a smartphone app during student teaching, matching the asynchronous aspects of the telepractice model and representing the effects of vocal loading from teaching.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Behavioral: Telepractice Global Voice Prevention Model | Experimental | Participants will complete the Global Voice Prevention Model (GVPM) through West Chester University's Desire 2 Learn (D2L) software program. Synchronous and asynchronous learning opportunities are provided through D2L over a four week period. The GVPM includes vocal hygiene, vocal education, and vocal training. |
|
| Behavioral: In-person Global Voice Prevention Model | Experimental | Participants will complete the Global Voice Prevention Model (GVPM) at West Chester University in-person. The GVPM will meet for 2 hours once a week for four weeks. The GVPM includes vocal hygiene, vocal education, and vocal training. |
|
| Behavioral: Telepractice, Vocal Hygiene and Vocal Education | Sham Comparator | Participants will complete Vocal Hygiene and Vocal Education through West Chester University's Desire 2 Learn (D2L) software program. Asynchronous learning opportunities are provided through D2L over a one week period. |
