Which of the following is not considered a violation of client privacy?

The correct answer demonstrates adherence to professional standards regarding client privacy. Documenting treatment notes within secure systems is an essential practice in psychology that protects client information. It ensures that sensitive data is stored in a manner that prevents unauthorized access, thus maintaining client confidentiality. Secure documentation practices are critical components of ethical guidelines for mental health professionals.

In contrast, the other options involve actions that compromise client privacy. Sharing information with a client’s family without consent could potentially violate the principle of confidentiality, as it involves disclosing private details to individuals who have not been authorized by the client. Discussing a client's case in a public setting can lead to unintentional revelation of identifiable information, which constitutes a breach of confidentiality. Providing case details for supervision is permissible, but only if it is done with confidentiality in mind and ideally with the client’s consent, so doing so without proper safeguards could be problematic.

Thus, maintaining the integrity of treatment notes within secure systems is vital for protecting client privacy and is not a violation in any context.
