How should I cite my personalized MBTI report in APA Style?
Since your MBTI results are only available to you, you can consider the report as "personal communication". Personal communication (e.g., a phone call, conversation, interview, email, lecture, non-archived discussion group posting) does not provide recoverable data; therefore, the resource is only cited within the text but not in the reference list (American Psychological Association, 2010, p. 179). When citing personal communication, provide the first initial and last name of your contact or the group/corporate name, “personal communication”, and the date the communication took place. It is unnecessary to specify the type of communication within your citation. For example, (J. Greenwood, personal communication, January 15, 2004), or J. Greenwood (personal communication, January 15, 2004). In the case of your MBTI report, please cite the authors of the report as the source of the information.
