Abstract: | The task of defining boundaries and boundary violations in the therapeutic relationship is examined from several perspectives. This paper reviews the ethical rules of the major mental health associations and the American Medical Association to determine the professions' ethical positions with regard to boundary maintenance and boundary violations. It also analyzes judicially sanctioned causes of action for recovery by clients for damages suffered as a result of boundary violations. The authors examine the ways in which fiduciary theory is used in the formulation of the ethical rules and to support the imposition of civil liability for boundary violations. The authors conclude that fiduciary theory provides a useful paradigm for setting and evaluating boundaries that acknowledge and address the fiduciary nature of the therapist–client relationship. The authors point out that measuring boundary violations with the yardstick of fiduciary duty serves the interests of both the client and the therapist. © 1997 John Wiley & Sons, Ltd. |
