APA reference lists only include works that can be found by the reader. As a personal interview is not published or “findable,” it should not be included in an APA reference list. Instead, a personal interview should be referenced as a parenthetical citation. For example: (J. Smith, personal communication, May 17, 2008).
If you would like to include a personal interview as part of your APA reference list, then include the interviewee, the date of the interview, and the type of interview.
Last name, FI. (Year, Month date). Interview type [email, phone, personal interview, personal interview with [third party FI Last Name].
Cloyd, A. (2014, July 29). Personal interview.
