Informed consent is the process of obtaining knowledgeable, rational, and voluntary agreement from study participants, which includes explaining the purpose, procedures, risks, and benefits of the study. Beneficence refers to the researcher's duty to minimize harm and maximize benefits to the participants. Autonomy refers to the participants' right to make independent decisions about their involvement in research. Verbal consent is a form of obtaining consent, but it may not always meet the criteria of being knowledgeable and voluntary.
