Step-by-step explanation:
According to the Tri-Council Policy Statement Ethical Conduct for Research Involving Humans, the three general principles of consent are: Respect for Persons, Concern for Welfare, and Justice. These principles emphasize the importance of treating research participants with dignity and respect, ensuring their welfare throughout the research process, and maintaining fairness in the treatment of all participants. This reflects a broader set of ethical guidelines that include principles of autonomy, ensuring that individuals have the freedom to make informed decisions; beneficence, which is the responsibility to do good and act in the best interests of the participants; and non-maleficence, the duty to do no harm. These principles guide the ethical conduct of research, ensuring participants are entered into trials only after giving informed consent, are treated fairly, and that their information is kept confidential.
