Research Participant FAQ and Resources


General Information

What research involves human participants?

Different types of research projects can involve people. Investigators conduct these research projects to answer questions and gain knowledge that they hope will benefit society.

Investigators may do things to research participants with their agreement, or investigators may ask participants to do specific activities and obtain information from them to answer research questions. Research involving human participants must follow specific rules created by the US government to ensure that research participants are treated with dignity and respect, and that the research causes minimal harm.

What is a research participant?

A research participant is an individual who participates in a research study. Information (or data) is collected from or about the individual participant to help answer the question under study. Research participants may also be referred to as study volunteers.

Who can participate in research?

Each study has its own set of criteria to determine who is eligible to participate. Eligibility depends on the research questions being asked and may include restrictions based on age, behaviors, health, or other factors. Before you enroll in a study, researchers may ask questions to determine if you are eligible to participate.

What is a clinical trial?

According to the National Institutes of Health, clinical trials are research studies that are aimed at evaluating a medical, surgical, or behavioral intervention in humans participating in the studies. They are the primary way that researchers find out if a new treatment, like a drug or diet or medical device, is safe and effective in people.

What is a principal investigator?

The principal investigator or PI is the individual responsible for the planning and conduct of a research study. At UT, this person is usually a faculty member.

Who oversees research involving human participants?

UT’s Human Research Protection Program and Institutional Review Board oversee all research activities involving human participants that are conducted by faculty, students, and staff at the university. The HRPP and the IRB work together to ensure that the rights, safety, and welfare of participants are protected and that UT researchers comply with all applicable federal and state laws and regulations.

Informed Consent

What is informed consent?

Informed consent is the process of informing potential study participants about what is involved in taking part in a research study and, if they are interested, having them officially agree to participate.

Typically this process includes the following steps:

  • Asking the potential participant to review written study information
  • Giving the potential participant time to review the information and consider participation, taking it home to discuss with others if desired
  • Giving the potential participant time to discuss the information in the consent form with researchers and to ask them questions about the study

As a participant in a study, your decision to participate is voluntary and you may change your mind at any time.

What are the different types of informed consent?

Depending on the type of study, participants may be asked to sign a consent form, to give consent verbally, or to check a box online. The researcher should always give you the option to keep, save, or print a copy of the consent document.

Under Tennessee law, minors under the age of 18 are generally not allowed to consent for themselves, and parental permission may be required for them to participate in a study. In this case, the study team will also ask the child whether they want to participate in the study. This process is called obtaining assent from the child. Learn more about research involving children.

What questions should I ask before agreeing to participate in research?

You have a right to know what the study you are considering is about and to know what you will be asked to do during your participation in the study. Please do not hesitate to ask the principal investigator or other research study personnel the following questions to inform your decision:

  • Why is the research being done?
  • What will my role in the research be?
  • How will I benefit from the research?
  • What are the risks to participating in the research?
  • What will the researcher do with my information?
  • Will the research cost me anything?
  • How long will the study last?
  • What happens if I decide to leave the study early?

What Should I Know as a Research Participant?

Why should I participate?

Research at UT is designed to benefit society. While most research does not directly benefit the participant, most people participate based on the possibility of helping themselves or others in the future.

What information should I receive from the researcher?

The researcher will usually provide you with the information listed below. Information may vary depending on the type of study.

  • Why the study is being done
  • Why you are being asked to participate
  • How long your participation will last
  • What will happen during the research process
  • Any expected risks or benefits you might experience
  • Any expected costs to you
  • What you can do instead of participating
  • Reasons you might be asked to leave the research
  • Whom you can contact for questions about the research and your rights as a research participant
  • Whether your information will be used in future research
  • Your option to withdraw from the study at any time without any penalty and without having to give a reason

What can I expect if I decide to participate?

You will be given information about the study so that you can make an informed decision about whether or not to participate. You will also be given the opportunity to ask questions about the study. This process is called informed consent. Before beginning the study, you need to agree to participate (that is, provide your consent). Participation is always voluntary.

Once you provide consent, the specific procedures or activities you’ll be asked to complete can vary depending on what is being studied. All the activities you will complete will be described to you during the consent process.

Who else will know I’m participating in the research?

Members of the research team and, when appropriate, others who have permission to see your records will know that you are participating in research. If other people will have permission to see your research records, they will be listed in the informed consent for the study. Otherwise, information about your participation is kept confidential unless you choose to tell someone.

How am I protected as a research participant?

Research studies involving humans must be approved and monitored by UT’s Human Research Protection Program and Institutional Review Board. The IRB confirms the following points about each study involving humans:

  • There is a good reason to conduct the study.
  • The risks related to participating are the least possible.
  • The risks related to participating are reasonable given the knowledge that will be gained from conducting the study.
  • The plan for selecting participants is equitable (that is, everyone who is eligible has an equal chance to participate).
  • Participants will be provided enough information about the study, in an understandable manner, to make an informed decision about participation.

Will I be paid for participating?

Some studies offer payment to participants; others do not. If payment is provided, it is usually only enough to cover expenses related to participation, such as parking, transportation costs, or time, and should not be enough to convince you to take risks that you normally would not take. If the study offers payment, the arrangement and amount will be explained in the informed consent process.

If you leave before the end of the study, check the consent form and confirm with the research team about compensation.

What are the benefits of participating?

Your participation contributes to UT’s research mission to make life and lives better by finding new information and creating new solutions to societal or scientific problems. While most research may not have a direct benefit to you as a participant, it is intended to advance scientific progress and benefit society.

What happens if I leave a study?

Your participation in research is voluntary. You always have the right to leave the research at any time and for any reason, and you do not have to explain your decision to stop participating.

What happens when the study ends?

The consent form will outline what is involved in participating in the study and will let you know what to expect when the study ends. If you want to see the results from the study, you should ask the investigator about this before you enroll.

How can I file a complaint or concern about a study?

Please contact the principal investigator who is listed on the consent form. You can also contact the Human Research Protection Program at [email protected] or 865-974-7697 if you have questions about a study or your rights as research participant.
