Interviews are often an integral part of gathering information, and can provide insight impossible to find elsewhere. Citing interviews adds credibility to your work and allows the reader to know where to search if she wants more information. Following a few guidelines will allow you to use American Psychological Association rules to properly format interview questions.
Immediately after the interview information in text, include the respondent's first initial and last name, the phrase "personal communication" and the full date of the interview in parenthesis. For example: (L. Johnson, personal communication, July 1, 2010). Because the interview is a personal communication, APA guidelines do not require the source to appear on the reference page.
For interviews that are found in a collection -- such as an archive -- list the interviewee's last name and the year of the interview in parenthesis immediately after the in-text interview information. For interviews that are found in a printed source -- such as a periodical -- list the interviewee's last name, the year of the interview and the corresponding page number in parenthesis immediately after in-text quotations of interview information.
For example: (Michaels, 2013, p. 12).
Printed interview sources must appear on the reference page. Double-space all references and use hanging indentation. Include the author's last name and first initial, date of interview, title of interview, title of source, volume and number of source and corresponding page numbers. For example: Michaels, J. (2013). Highway to health. Shape (italicized), 32(10), 11-16.
