Other info to think about when joining a study

You may see or hear the word “proxy” used in cases when participants who are legally not able to make research decisions for themselves are being recruited into a study. For example, a proxy might be needed in a situation where someone has a head injury or is so sick that that they are not able to talk or sign the consent form.

If you are a proxy for someone else, feel free to ask the study team any questions you have about the research study.
