One drawback of online consent is the lack of face-to-face contact
during the consent process. As a result, the interviewer may not be
able to ensure participant understanding of the consent form in the
sameway they can in a face-to-face interaction. This is not unique to online
consent, however, as it is also true for mailed surveys. In an argument
in favor of obtaining online consent, Moreno et al. [93] suggest
that people who are accustomed to online interactions might be even
more likely to reach out to an investigator with questions than those
in a face-to-face situation.While this has not been addressed systematically,
it is possible that greater use of e-technology can improve interactions
between researchers and participants
