Human subjects research is subject to approval by OU's Institutional Review Board (IRB). This approval includes reviewing your informed consent document. The informed consent form should explain how you are going to protect the privacy and confidentiality of your study participants. However, you don't want to overly restrict or prohibit sharing or preserving of the data created in the research project.
Overly restrictive language for informed consent forms
"Your responses will only be seen by the research team"
"All data will be destroyed after project completion"
"Your data will only be shared in aggregate form or in statistical tables"
