The task of defining boundaries and boundary violations in the therape
utic relationship is examined from several perspectives. This paper re
views the ethical rules of the major mental health associations and th
e American Medical Association to determine the professions' ethical p
ositions with regard to boundary maintenance and boundary violations.
It also analyzes judicially sanctioned causes of action for recovery b
y clients for damages suffered as a result of boundary violations. The
authors examine the ways in which fiduciary theory is used in the for
mulation of the ethical rules and to support the imposition of civil l
iability for boundary violations. The authors conclude that fiduciary
theory provides a useful paradigm for setting and evaluating boundarie
s that acknowledge and address the fiduciary nature of the therapist-c
lient relationship. The authors point out that measuring boundary viol
ations with the yardstick of fiduciary duty serves the interests of bo
th the client and the therapist. (C) 1997 by John Wiley & Sons, Ltd.
