If you are considering participating in a research study, you’ll want to know what to expect about the study activities involved, the time and cost to you to participate, how you will benefit, and what might be the risks of participating. If the study is being conducted in a clinic, a member of the research team, usually a doctor, nurse, or study coordinator, will talk to you about the study and what to expect. The details of the study will be outlined in an informed consent form, which you will be asked to sign if you decide to participate in the study. Informed consent is not a contract, so you are free to withdraw from a study at any time. If the study is being conducted over the phone, on the internet, or by mail, you should still be provided with information about the study, but you may not have a conversation with the research team or be asked to sign an informed consent form.
