Dual relationships exist whenever a therapist interacts with a client in any capacity beyond the one role as therapist, for example, also being their client's teacher, consultant, business partner, or sexual partner. If you perform a role other than therapist for your client, it may introduce desires and goals that are yours rather than the client's and can risk the possibility that you will place your needs above theirs. Maintaining unselfish judgment is critical to your role as an effective, professional therapist. According to APA Ethics Code (2002) 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, at the same time is in a relationship with a person closely associated with or related to the person with whom the psychologist has the professional relationship, or promises to enter into another relationship in the future with the person or with a person closely associated with or related to the person. APA states that a psychologist refrains 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. Multiple relationships that would not reasonably be expected to cause impairment or risk exploitation or harm are not unethical. If a psychologist finds that, due to unforeseen factors, a potentially harmful multiple relationship has arisen, the psychologist takes reasonable steps to resolve it with due regard for the best interests of the affected person and maximal compliance with the Ethics Code. When psychologists are required by law, institutional policy, or extraordinary circumstances to serve in more than one role in judicial or administrative proceedings, at the outset they clarify role expectations and the extent of confidentiality and thereafter as changes occur.
