Informed consent is the process through which a researcher obtains, as well as maintains, the permission of a person or a person's authorized representative to participate in a research study. Informed consent is achieved when participants [a.k.a., "human subjects"] in your study receive full disclosure of the research plan and its intent, understands all of the information that is disclosed to them, voluntarily consents to participate in the study and is competent to do so, and understands that they may withdraw from the study at any time.

One of the most important ethical rules governing qualitative research applied to conducting field studies is that individuals must voluntarily give their informed consent before participating in a study. However, the conditions under which you may be required to obtain permission from those being observed varies. For example, observations taking place in open, public spaces, such as in a park or at the beach, usually does not require informed consent because there is no expectation that you cannot be observed. However, there is likely an expectation of obtaining consent in a bounded observational space, such as, a classroom, a homeless shelter, or a hospital emergency room.
In most cases, you will need to obtain informed consent from those you are studying. According to the U.S. Office for Human Research Protections, the Code of Federal Regulations requires that specific information be provided to research subjects before they participate in a study. Rules related to conducting qualitative research in the social sciences [rather than in the medical sciences] at USC are governed by the University Park Institutional Review Board [IRB]. If you are asked to write a field report involving methods of observation, be sure you speak with your professor about the preferred process for obtaining consent, if needed, and that you understand the required procedures for obtaining informed consent.
Guidelines for writing an informed consent to be signed by each participant generally includes the following:
NOTE: The informed consent forms that you and your research subjects must sign have to be written in plain language. In addition, the form should not contain any exculpatory language. That is, subjects should not be asked to waive [or appear to waive] any of their legal rights, nor should they be asked to release the investigator or the university from liability for negligence.
