: According to Resolution 510 of April 07, 2016, from the Brazilian Health National Council (<i>Conselho Nacional de Saúde</i>), and considering the ethics, history, social, and cultural aspects related to research in the Social and Human Sciences, registration or evaluation of this research with the ethics committee of the University is not required. The first paragraph of the Resolution 510 states that “research of public opinion in which the participants are not identified” does not need to be registered nor evaluated by the ethics committee. Additionally, the informed consent from participants was obtained in the first step of the online questionnaire (please see InternalRef removed—online questionnaire). We start by explaining the terms of the research and emphasizing that the participant’s information will remain anonymous and the system will not register the names of the respondents. Then, we formally ask the participants if they are willing to partake in the study.
