Volunteers are always fully informed of the study requirements, required visits, tests, procedures, etc. Additionally, volunteers are always made aware of any known or likely risks of a study or any new risks that are discovered during the study. Volunteers should ask as many questions as they need in order to feel comfortable with
participating. Make sure that you know exactly what will be required of you and that you are willing to perform the required tasks in the study.
Also make sure that you understand the benefits and risks of the study and that you can accept the risks of participating. You may also request to speak directly with the principal investigator of the study, and you may want to discuss the study with your primary care physician (PCP) prior to agreeing to participate.
One of the most important things to remember is that participation in a clinical research study is always voluntary and optional, and you can stop participating at any time. Ethical laws and regulations prevent participants of clinical research studies from being given undue influence or from being coerced into participating or continuing to participate.
