What constitutes a breach of confidentiality in research?

A breach of confidentiality in research primarily involves the unauthorized disclosure of personal information that could identify a participant. This is critical because protecting participants' identities and personal data is fundamental to ethical research practices. If confidential information is revealed without appropriate authorization, it compromises individual privacy and can lead to adverse consequences for participants, including harm to their reputations or potential stigmatization.

The other options may suggest situations that seem related but do not define a breach of confidentiality in the same manner. For instance, unauthorized public presentations of participant data can be problematic, but it depends on whether identifiable information is shared. Accidental sharing of general research findings typically does not involve personal identifiers, while failing to anonymize responses relates to the methodology of data handling rather than directly to the breach of confidentiality per se. Each of these scenarios may raise ethical concerns, but they do not encapsulate the core aspect of confidentiality violations as effectively as the unauthorized disclosure of identifiable information does.
