Most online surveys or interviews require consent. The online consent
process typically comprises reading through a series of questions
and indicating comprehension of procedures, risks and benefits, and
voluntary participation by checking a box. Researchers and IRBs may
be more comfortable with online consent prior to online surveys or interviews,
which can be seen as ensuring greater confidentiality than
face-to-face interviews or paper surveys, since names and location
data (phone number, address) may not be collected.
