The purpose is to foster understanding of ethical standards in health care research. Each student will contribute to each of the questions posed; students are not assigned to individual questions. Group discussion will address ethical standards and approaches relevant to your own approach to research: (a) which approaches are proposed to recruit a representative sample of participants? (b) which procedures are proposed to establish informed consent? (c) which approaches are proposed to assure privacy and confidentiality of personal information? (d) which approaches are proposed to minimize physical, psychological, social, or other risks to participants?
