If it is a research interview it should never be individually cited or treated as personal communications in APA Style, because this could compromise confidentiality. Researchers are prohibited by the APA Ethics Code from disclosing personally identifying information about research participants.
You can cite from your research interviews in different ways:
- Some authors quote participants without distinguishing them at all, like this: “Indeed, a comment by one of our participants illustrates some of these complex issues: [quote follows without other attribution].”
- Others identify participants by demographic or other data: “At my age I think we know who we are and what we are. (Female participant, 69 years of age).” You can also identify participants with letters (Participant A, Participant B), nicknames (Sonny, Tracey), or by role (Manager, Worker)
Choose one that best helps your reader.
