Consent in research refers to the process of informing participants about the purpose, procedures, risks, and benefits of a study, and obtaining their voluntary agreement to participate. This process is essential in ensuring that participants are fully informed and able to make a decision about whether or not to take part in a study. Informed consent is generally obtained through a written consent form that outlines the key information about the study and the rights of the participant. Researchers are responsible for obtaining and documenting consent from all participants before beginning any research activities. Failure to obtain proper consent can result in ethical violations and may invalidate the study results.
