What is a research study?
研究是医生和科学家了解预防和治疗状况的新方法，并找到有关健康，疾病或人类行为的许多问题的答案。作为研究的参与者，您在改善医疗保健和未来治疗方面发挥着关键作用；但是，这也是一个重要的个人决定。
Some participants may have a disease or condition the researchers are studying, while other participants are healthy volunteers. In each research study, there are requirements regarding who can participate. This is called inclusion criteria. There also are reasons why someone might not qualify, known as exclusion criteria.
Being part of a research study is completely voluntary, and you can change your mind at any time.
The research team
Every study has a research team who work together to follow what's called a "protocol" — a detailed plan for the study. The protocol balances the potential benefits and risks to participants, and answer specific research questions.
研究team members include:
- Principal investigator (PI): The PI, who is often a doctor or scientist, is responsible for the entire study. This person plans the study, makes sure activities are done safely and correctly, and decides what each research team member does. The PI supervises all research activities and all of the members of the study team. The PI also makes sure everyone on the team has the proper training.
- Co-Investigators:许多研究都有与PI合作的研究人员（通常是医生或科学家）。共同投资者可能会帮助PI设计或监督研究，但对整个研究不承担任何责任。
- 研究护士：A research nurse often has special training and experience. Many studies that involve medical or clinical research have a research nurse on the team who helps carry out the study, focusing on the care and safety of research participants, and is often involved in coordinating daily study activities.
- 研究coordinator/research assistant:The research coordinator/research assistant is a person who works with the other research team members to organize and help with daily study tasks.
Other individuals also may help with a research study, such as pharmacists, lab technicians, dieticians who help with participants dietary needs, social workers and office staff.
