2.4. Questionnaire

For this survey, we built an online questionnaire using the free service, Google Forms. A pilot version of the questionnaire was tested with three SLPs in order to identify and adjust wording that lacked clarity. We estimated that it could be completed within approximately 20 min. An English translation of the final version of the French-language questionnaire is available in the Supplementary Material. The questionnaire was divided into three independent parts: knowledge and use of (1) singing, (2) melodic therapy, and (3) choral singing as therapeutic tools in ANCD. Each part consisted of closed and semi-open questions (multiple choice including “Other” with a request for precision) and an open-ended question. Some questions were presented conditionally based on answers to previous questions using the redirection system included in the online survey platform, so not all respondents had to answer all questions. The number of responses for each question is reported in the results.
