Promise of confidentiality

A promise to a respondent or research participant that the information the respondent provides will not be disseminated in identifiable form without the permission of the respondent; that the fact that the respondent participated in the study will not be disclosed; and that disseminated information will include no linkages to the identity of the respondent. Such a promise encompasses traditional notions of both confidentiality and anonymity. In most cases, federal law protects the confidentiality of the respondent's identity as referenced in the Promise of Confidentiality. Under this condition, names and other identifying information regarding respondents would be confidential.

Research subject

A person or organization that participates in a research study. A research subject may also be called a respondent. A respondent is generally a survey respondent or informant, experimental or observational subject, focus group participant, or any other person providing information to a study.
