Under what condition can psychologists share patient information without consent according to the Code of Ethics?

The correct choice is founded on the principle of confidentiality in psychological practice. Psychologists have a primary obligation to protect their patients' privacy and confidential information. However, there are situations where sharing information may be permissible without consent, particularly when it is done in such a way that anonymity is preserved.

In this context, when classroom materials adequately disguise the identity of the individuals involved, psychologists may share relevant information for educational purposes, such as training or supervision, without breaching confidentiality. This aligns with educational practices and reduces the risk of harming the individual’s privacy.

The other options do not align with the accepted ethical standards. For example, the "best interest" rule is more subjective and does not provide a clear guideline for when information can be disclosed without consent. Similarly, a family member’s request for information does not constitute a valid reason for breach of confidentiality unless there is a clear legal or ethical obligation to do so. The last option deals with a situation where a patient threatens serious property damage, raising significant ethical concerns. While that scenario might allow for a breach of confidentiality in some jurisdictions under duty to warn laws, it does not pertain to general conditions for sharing patient information without consent according to the Code of Ethics.
