Empirical survey data

The vocal stigma questionnaire was developed in consultation with an expert panel, including: (a) a speech-language pathologist with over 10 years of experience working with clinical voice disorders; and (b) three professional vocal performers (one actor, one singer, one actor/singer; each with over 20 years of experience) from the Alliance of Canadian Cinema, Television and Radio Artists (ACTRA) or the National Association of Teachers of Singing (NATS). The questionnaire consisted a total of 64 items to survey individuals’ demographics (6 items), occupation and training (3 items), vocal health history (14 items), IMB profile (30 items, 10 each for information, motivation, and behavioral skills), experiences of vocal stigma (10 items, 5 each for social-stigma and self-stigma) plus a single, open item for feedback.
