Program Overview

This course offers an overview of the legal and ethical issues pertaining to a therapist’s duty to warn and protect in cases where a patient may commit violence. It begins with a discussion of the 1968 case of Tatiana Tarasoff, which established legal precedent for a duty to warn. Then, using illustrative examples and interview material, it surveys how different states implement the duty to warn and protect, provides a framework for determining when and how to intervene with a potentially violent patient, and offers ethical guidance for balancing confidentiality with the safety of patients’ potential victims.

Target Audience

This continuing education activity has been designed for investigators, research team members, physicians, nurses, social workers, psychologists, therapists, and other healthcare professionals who have an interest in the legal and ethical issues pertaining to a therapist’s duty to warn and protect in cases where a patient may commit violence.

By the end of this course, participants should be able to do the following:

  • Describe the facts of the Tarasoff case
  • Explain the ethical foundations of the duty to maintain confidentiality and the duty to warn and protect
  • Distinguish among laws and policies pertaining the duty to warn and protect in different states
  • Make use of the framework of the Appelbaum method in cases where Tarasoff duties may apply

In this activity, learners will engage with the content by moving through a series of brief video lectures with links to related readings, downloadable resources, and quizzes.
