Should I use an electronic signature or button based consent?
The decision is entirely yours – and will likely be heavily influenced by your institutional review board.
We find that studies that include some kind of biomedical intervention that is beyond something an individual would do on a day to day basis tend to require more than just a button based consent. Studies with experimental treatments and treatments that have a high degree of risk or side effects also require more than a button based consent.
Studies that test materials that are readily available to consumers over the counter generally do not.
Use your judgement and consult with your IRB.
