Commonly Asked Questions Explained

It is research that involves people. Investigators do research to answer questions and gain knowledge that they hope will benefit society. Investigators may do things to research participants with their agreement or ask participants to do specific activities and obtain information (such as health information) or biological samples (such as blood) from them to answer the research questions.

For example, investigators may give participants new medicines to take, collect their blood, and obtain their information to see whether the new medicine is safe and works. Investigators may also ask participants to view different images to see how they respond emotionally. These are both examples of research that involve people, or human subjects research. In addition, investigators may simply study the information or biological samples already collected from people, for example, from routine medical care.

There are different kinds of human subjects research, explore the links below to learn more!

To learn more about research and research participation, review the short videos at https://www.hhs.gov/ohrp/education-and-outreach/about-research-participation/informational-videos/index.html.
