Final answer:
A deliberate or intentional breach of confidentiality occurs when a therapist knowingly discloses confidential information. This action is typically only justified in specific circumstances, such as if there is an imminent risk of harm. Breaching confidentiality is a serious ethical violation in therapeutic practice.
Step-by-step explanation:
Deliberate or intentional breach of confidentiality in a therapeutic setting is indeed when the therapist is fully aware that the information is confidential, yet decides to disclose it knowingly and with deliberate intent. This could be motivated by various reasons but must typically be justified by strict guidelines such as imminent risk of harm to the client or others. In the context of therapy, confidentiality is a cornerstone of the therapeutic alliance and ethical practice, and breaches are taken very seriously within the profession.
