Re: [Air-L] informed consent

We used two ways to collect informed consent. In our national mail survey, two documents were included: one cover letter and the other consent information. In the consent information, we indicated that when the respondent returned the questionnaire, it represented his or her consent to participate in the survey. We also set up an online version for the respondents to participate in the survey. After the respondents logged in, the same consent information appeared and the respondents must click on a button to indicate their consent before answering any questions. Best regards.
