APA stance is that a psychologist should refrain from entering into a multiple relationship if the multiple relationship could reasonably be expected to impair the psychologist's objectivity, competence, or effectiveness in performing his or her functions as a psychologist, or otherwise risks exploitation or harm to the person with whom the professional relationship exists.
A multiple relationship occurs when a psychologist is in a professional role with a person and at the same time is in another role with the same person,
In such a situation as above The psychologists would be expected to choose one role and leave the other role to another psychologist since his effectiveness would be impaired
