Ethics approval and consent to participate

: The Office of Research Compliance at Indiana University approved the study protocol data collection. Our survey method was to canvas every subject who approached the intercept point at the assigned time and location. As we intercepted each subject or group of subjects, they were given a short explanation of the study asking them to consider participating in the survey. The participants were then given an information card to access the survey online If they wished to participate. If the participant chose to access the survey online, the first question was their consent to participate in the survey and the eligibility (aged 18 years or older) to participate. No participant was asked to participate in the survey by an individual at the intercept site. Using this approach, no consent was required as it was stipulated in writing during the participants introduction to the survey. The institutional review board approved the consent procedure.
