Ethics approval and consent to participate
: Ethics approval for the project was received from the Ethics Review Committee of Zhongnan Hospital of Wuhan University with the approval number 2018079. It is an online anonymous survey for which it is impossible to obtain written or verbal consent, and this was approved by the ethics review committee. In the “Ethical Approval and Consent to Participate” section we have explained that participant’s consent was obtained online in the form of requiring readers to review an informed consent statement before the questionnaire popped up. If someone refused to consent then the questions would not appear. Therefore, completion of the questionnaire implies consent. Moreover, written informed consent was obtained from the two 10-year-old girls who helped us test the readability of sf-DCS and their parents.
: We have obtained consent to publish from the participant (or legal parent or guardian for children) to report individual patient data. The information about the study included informing the participants of the intent to publish the results of the study so this was included when they checked the informed consent to enable them to proceed with the survey.
