Final answer:
The 'Duty to warn' condition requires mental health professionals to breach confidentiality to notify potential victims of serious threats by their patients, a principle from the Tarasoff v. Regents of the University of California case, overriding usual confidentiality to protect individuals from harm. The correct option is 4.
Step-by-step explanation:
The condition you're referring to when a client expresses a serious threat of violence toward an identifiable victim is known as the Duty to warn condition. This principle compels mental health professionals to breach confidentiality in order to protect the potential victim.
This condition was established by the landmark legal case Tarasoff v. Regents of the University of California. It imposes a legal obligation to warn identifiable victims of any serious threats of harm made by patients during therapy sessions.
While the Confidentiality condition typically requires professionals to preserve patient privacy, the Duty to warn overrides this when there is an immediate risk of violence. The Informed consent condition requires professionals to inform clients about the nature of therapy, its risks, and the right to refuse treatment.
Understanding these conditions is critical for ensuring ethical practices that respect subjects' rights to privacy and dignity, protect subjects from personal harm, and preserve confidentiality while also seeking informed consent.
