The process of obtaining informed consent usually involves providing a written document that explains all these points, and having the participant sign it to indicate their agreement. In some cases, verbal consent may be sufficient, but this is less common and usually requires specific ethical review board approval. For vulnerable populations (e.g., children, cognitively impaired individuals), consent might need to be obtained from a legal guardian or representative.
