Prospective Teacher's Voice Questionnaire (PTVQ): Development of a Questionnaire to Assess Training-Related Voice Symptoms Among Prospective Teachers.

Aim: To develop and validate a self-administered population-specific survey, available in Spanish, Portuguese, and English, which investigates the prevalence of voice symptoms and perceptions of risk factors associated with training among prospective teachers.

From this phase, we defined five aspects of the Prospective Teacher's Voice Questionnaire (PTVQ): (1) target population, (2) research objectives, (3) questions to be included, (4) scales for the answers, and (5) relevance, comprehensiveness, clarityclarity, and understandability of the questions.
