An online-based survey was conducted during the summer of 2013, where all participants
agreed to their involvement in the survey by accepting the terms of the informed consent. The
informed consent page, which was approved by the Institutional Review Board, notified the
participants that the online survey was going to be confidential and anonymous. Participants were free to end their participation at any time. The removal of incomplete or nonresponsive
surveys left a total of 255 respondents.
